A KEY TO THE GENERA OF THE MENOPONIDAE (AMBLYCERA : MALLOPHGA : INSECTA)

By THERESA CLAY

SYNOPSIS

A review of the characters which have been used in the diagnosis of the genera of the Meno- ponidae is given, together with a number not previously used. A discussion of their taxonomic value is included, followed by a key to the genera and subgenera of the family.

PART I INTRODUCTION

IN formulating a key to the genera of the Menoponidae an attempt has been made to use characters which not only define each genus but also place at least some of the genera in larger groupings; these may prove in some cases to be phylogenetic. The greater number of species now available has shown that many of the former key characters cannot always be used or have only a limited application. These include presence or absence of postpalpal and antero ventral head processes; ctenidia on the 3rd femur and sternites; asters of spiniform setae on sternite II of Myrsidea; subdivisions of the flagellum ; number of prosternal setae ; shape of head and abdomen ; the characters of the dorsolateral margin of the head and hypopharyngeal sclerites. These characters may vary within groups of otherwise similar species or may be common to otherwise dissimilar genera. It is hoped that this key may give a clearer conception of the generic characters and their reliability in the taxonomy of the family. Only those structures of ectodermal origin and which can be seen satisfactorily without sections have been considered; the task of sectioning and examining a sufficient number of specimens of each genus would have been impossible and a number of the genera are represented only by specimens mounted on slides. Some characters have obviously been missed; also omitted are those which could not be seen clearly in all the available material or the morphology of which could not be correctly interpreted. There are also other characters which need further material and time for study, such as the segments and sensilla of the flagellum.

There follows a review of the characters of various parts of the body with a discussion of their taxonomic importance. These characters fall into four groups: those which are found throughout the Menoponidae and which are of little interest here, but are mentioned when they have been or might be included in generic descriptions; those which vary throughout a genus and are of specific value only; those which can be used for generic separation ; and those which group similar genera together. The same character can of course be specific in one group and generic in another. Two cases have been found in which a character, apparently unique for the Amblycera, is of no more than specific or of species-group value (see Comatomenopon elbeli Emerson abdomen and Meromenopon head setae). It is appreciated that the term ' generic character ' is not very meaningful considering how the generic concept

differs among workers on Mallophaga at the present time; elsewhere (Clay, 1947 : 457- 477 i I95I : I7I~I75 ) r953 : 5^i i 1966 : 332-333) the present writer's views on the genus have been made clear and need not be repeated. It is felt that at present there is little to be gained by attempting to group the genera into various families and other divisions.

Head

i. The Head Capsule. The basic structure of the head is similar throughout the Menoponidae (Buckup, 1959; Haub, 1967), but the form of the dorsolateral margin (Text-fig. 4) and its junction with the temple margin, the presence or absence of a preocular notch or slit, position of the eyes and the form of the antennary fossa provide useful generic characters. The presence or absence of a narrow preocular slit is usually constant in a group of otherwise similar species, but in Menopon there is variation from a deep narrow slit (M. interpositum Ansari) to a shallow narrow slit (M. gallinae] to an approximately straight margin (M. jellisoni Emerson). M. interpositum, for instance, with the abdominal characters typical of Menopon has the dorsolateral margin of the head similar to that of Amyrsidea perdicis. Variously developed ventral sclerotized processes arising near the anterolateral margin may be present or absent (e.g. Pacifimenopon Price) or occasionally present in genera in which such processes are not usually found (e.g. Machaerilaemus raggianae Price & Emerson, Kurodaia quatei Price); they are probably of little phylogenetic value. Processes arising near the base of the maxillary palp (postpalpal processes, Text-fig. 5) are usually more constant within genera, but may be present or absent in Nosopon and Pseudomenopon, for example; in the latter genus and in Colimenopon they may be present in the nymph and absent in the adult; it is also doubtful whether their presence or absence forms good generic characters for some of the species infesting the Galliformes. The presence of these processes is therefore only specific in some genera, but in others is probably generic (e.g. Kelerimenopon, Apterygon Clay and Hohorstiella) . The gular region has two or more setae each side and may or may not have a well-sclerotized plate; the form of this plate is a generic character in Pseudomenopon and Colimenopon.

The tentorium has been described by Symmons (1952 : 365) who showed its similarity in the species of Menoponidae she examined belonging to the genera Colpocephalum, Menopon, Menacanthus, Myrsidea and Ancistrona. In mounted specimens it is generally possible to see the anterior and posterior pits, the anterior tentorial arms and the tentorial bridge; differences are shown in the width of the bridge relative to the size of the head and the size of the posterior pits, but it is doubtful whether these will provide useful characters for the recognition of genera. In Eureum and Dennyus the bridge is narrowed centrally, but in some species this tends to be rather wider and would probably grade into that of some species of Myrsidea, for instance, which is broader than is usual in Dennyus but less broad than in some species of other genera. Symmons (1952 : 375) showed that there were some differences in the tentorium of Trinoton, mainly of muscle attachments, and of Piagetiella, in which parts of the bridge and anterior arms are difficult to see owing to some lack of sclerotization and to the heavy sclerotization of parts of the head.

KEY TO GENERA OF MENOPONIDAE 5

The degree of pigmentation of the internal carinae gives a characteristic appearance to the head and may be correlated with other characters to help in generic groupings. However, it seems to be a rather variable character; the quill-inhabiting species, for instance, having a tendency to lighter pigmentation (e.g. Comatomenopori).

2. The Head Setae and Sensilla. These tend to form constant patterns (Clay, 1960 : 573) and the dorsal head setae expecially may be useful for the recognition

of genera and generic groupings. They have been used extensively in the key, being referred to by numbers e.g. seta 23 ; those of taxonomic importance have been labelled in Text -figs. 1-4. On the anterior region of the dorsum there may be extra setae in some species of a genus or in one sex only and the setae of this region have not therefore been used. The lengths of 10 and n (the preocular setae) are useful specific characters ; the addition of one or more setae to this pair may be specific (Adornithophilus crinitus Clay) or generic (Meromenopon). Ancistrona has a row of fine setae along the inner dorsolateral margin (Text-fig. 20) not seen in any other

genus. Numbers 14-16 (setal complex and dorsal seta of Price & Beer, 1963 : 851) usually form a characteristic group, their position in relation to each other often being of specific importance. The size and position of 17 and 18 (the mid-dorsal head setae) may form generic (Cuculiphilus] or specific characters (e.g. Colpocephalum) ; the absence of 18 is a generic character in Myrsidea. The two ocular setae (19 and 20) seem to be always present : 19 usually lies near the division of the two ommatidia (when apparent) ; 20 is usually small and often marginal and difficult to see ; in Dicteisia it is well developed (Price, 1968) . The posterior marginal or submarginal temporal and occipital setae are numbered from the centre outwards as the first ten form useful taxonomic characters, whereas the anterior temporal setae are not always constant in number, and in mounted specimens may get confused with the ventral. The occipital setae (21-22) are always present and their relative length and thickness may form specific or generic characters. Seta 23 may lie anterior or anterolateral to 22 (Text- fig, i) or in a straight line with 21 and 22 (Text-figs. 2-3), often some considerable dis- tance across the temple; it is important to identify it correctly and not confuse it with 24 or 25. In Myrsidea seta 23 is always absent and in Bucerophagus it may be min- ute. Of the seven following marginal or submarginal setae (24-30), 29 and 30 in nearly all species can be recognized as 30 lies near and submarginal to 29, either being on the outer or on the mediad side ; in Trinoton it is nearer seta 27 ; in Numidicola it is marginal. The next marginal seta is 28, usually short and fine; followed by 27 and 26 which are either separated or have their alveoli contiguous or nearly con- tiguous; in this last condition 26 is usually fine and significantly shorter than 27. The position of these two setae is a constant feature within genera and groups of genera and is a useful key character. However, it does separate Bucerophagus, in which 26 and 27 are closely associated, from the otherwise similar genera Chapinia and Bucerocolpocephalum Elbel in which they are not. This leaves two setae, 25 and 24, one or both of which may be minute to medium to very long; the length of these setae may be a useful character, but in Machaerilaemus one or both may be missing and in other genera the lengths may vary. In those species with one long and two short setae between 23 and 27 (Text-fig, i) it is not always possible to number the long seta; it is usually submarginal to the two short marginal setae and may vary in its position relative to them. Ancistrona has extra setae: three long and two short between 23 and 28. In addition to these temporal setae, one of the setae anterior to 30 (here called 31) may be long and stout. The number of long setae may be generic (three in Eomenopon] or specific (two or three in Kurodaia, Price & Beer, I963 : 851). The lengths of the head setae are not always key characters owing to the known and potential variation and to the subjective interpretation of ' long ' and ' short '.

The dorsal head sensilla may be five in number (Text-fig, i), but there are more usually three: a. is not always apparent as it lies on the margin just anterior to seta 9; b. just posterior to 9 is useful for the identification of this seta; c. is usually present and associated with setae 14 and 15; d. associated with seta 16 and e. with 17 are less commonly present. The presence or absence of e. is a group character in Austromenopon, being present only in the species infesting the Alcidae; d. is absent in Actornithophilus species from the Lari, being present in species from other hosts; in

KEY TO GENERA OF MENOPONIDAE 7

Menacanthus from the Galliformes d. may be present or absent in different species. The absence of c. may be a generic or group character: in the Colpocephalum-complex c. is usually present, but appears to be absent in the species infesting the Galliformes and in a few of those on the Ciconiiformes.

The ventral head setae are mainly constant in number and position throughout the Menoponidae. The labral setae comprise a posterior row of usually closely arranged setae and an anterior row often with i, 3, 6 and 7 short and the remainder longer (Text-fig. 4). An examination of many species, however, shows that there is no clear distinction between ' long ' and ' short ' setae and there are many exceptions. This is not therefore usually a useful character, but in Ancistrona these setae are

diagnostic, being all minute with the exception of one long seta each side. In all species examined there are two setae, one long and one short, at the anterior end of the ventrolateral margin (Text-fig. 4 a .), posterior to these are one or more setae (s. subocular setae, Ryan & Price, in press), followed in most genera by the subocular comb row ( = lateroventral head fringe, Clay 1966 : 330). The first or only seta in group s. is frequently elongate and sometimes flattened and somewhat hyaline (e.g. Eidmanniella ; PI. 4, fig. 20) ; in Meromenopon from the Meropidae this seta is flanged with at least one tooth (PI. 3, figs. 15-16), being unlike any other seta seen in the Mallophaga ; in the congeneric species from the Coraciidae the seta is normal. The presence of only one seta in group s. may be a specific or generic character; in Eomenopon and Pacifimenopon the elongate seta may not be the most anterior one. In some cases it is not always possible to separate some of the setae of group s. from the comb row. The subocular comb row (PI. 4, fig. 19) is characteristic of the

8 THERESA CLAY

Menoponidae, but is absent or atypical in Microctenia, Machaerilaemus and A ncistrona ; in the latter genus its function may have been taken over by the row of setae along the inner edge of the dorsolateral margin. In some genera (e.g. Colpocephalum) there is a ventral patch or line of submarginal setae on the anterior region of the temple (PI. 4, fig. 21) ; this should not be confused with the subocular comb row and the seta continuous with this row which in mounted specimens may appear submar- ginal. In Kelerimenopon a band of thickening runs inwards from the ventrolateral margin with at least one seta. The histology of the setae and integument of the Menoponidae is discussed by Neuffer, 1954.

3. The Antenna. In all Menoponidae the antenna (PL I, fig. i) comprises the scape, pedicel and a flagellum of usually two segments, the terminal one sometimes being subdivided. The distal anterior angle of the scape and pedicel may be produced laterally (Trinotori) or the pedicel alone (Mimemamenopon Carriker) forming generic characters; the latter condition may also be only specific (Ciconiphilus, Hohorstiella). In one species of Eidmanniella three of the distal setae of the pedicel are broad and hyaline (Ryan & Price, in press). The first segment of the flagellum is always pedunculate or wineglass-shaped. Ferris (1923 : 57) discussing Menopon and Tendeiro (1967 : 384) Chapinia, considered that this segment was divided into two, the first being small and formed by a line across the ' stalk ', the part proximal to the line being darker in colour. This condition is apparent in many species belonging to many genera : in Bucerophagus productus there is no sign of an external structural division (PL I, fig. 2) and no break of the internal marginal thickening; the apparent segmentation may be due only to the difference in pigmentation. In Myrsidea cornicis and Pseudomenopon pilosum in which this line is apparent, reconstructions of the antennae from sections by Buckup (1959) and Haub (1967) show no break in the pedunculate segment, these authors describing it as a single segment. It would therefore be more satisfactory to treat it as such. Keler (1958 : 82) in the original description of Eidmanniella stated that the antenna appeared three-segmented as there was only a trace of the line of division between the two segments of the flagellum; stereoscan photographs of this type of antenna (PL i, fig. 4) show a definite division, but perhaps not so marked as in some other species (PL 3, figs. 13-14). The second segment of the flagellum, usually referred to as the terminal antennal segment, may be globose to elongate, the shape frequently being similar in the species of a genus. The surface of this segment is ridged (PL 2, figs. 7-12) and it is these ridges when deep and in a straight line which may give a false impression of a subdivision of the segment. It is possible that the form of these ridges and the sculpturing of their edges (PL i, fig. 3) may provide further taxonomic characters. The distance apart of the ridges, visible with the light microscope, has been used in the key to separate two groups (PL 3, figs. 13-14). The form of the sculpturing of the third segment may also prove to be a taxonomic character. Distally there are a number of setae, sometimes cone-shaped (PL 3, fig. 13) and two sensilla which seem to be sensilla coeloconica (PL 3, fig. 13; PL 7, fig. 42). In species with the last segment subdivided, one of these sensilla is proximal to or near the dividing line (Cuculiphilus, PL I, fig. 3), suggesting that the primitive condition may have been a three-segmented flagellum with a sensillum on each of the two terminal segments. Whether the last

KEY TO GENERA OF MENOPONIDAE 9

segment is subdivided or not has frequently been used as a generic character, but it now appears that this may not always be reliable. In Cuculiphilus there is a well marked division internally and externally (PL i, fig. 3). In Bucerophagus productus there is an internal break in the marginal thickening and the part proximal to this is slightly more darkly pigmented, but externally there is no definite division (PL i, fig. i); one of the sensilla lies proximal to the internal division. Some species of Menacanthus also show a break in the internal marginal thickening of the terminal segment without any other indication of a division, so that the presence or absence of an internal break may not be relevant. It would seem that in B. productus the appearance of a division is partly due to the slight change in pigmentation and partly to a deep furrow between the ridges (PL 2, figs. 7-9). In B. africanus similar photographs (PL 2, figs. 10, 12) suggest that there is a definite division; there is also a marked difference in pigmentation in this species, the part proximal to the line of division being darker in colour. This segment in some species of Colpocephalum resembles that of B. productus in having the proximal part more darkly pigmented and the two sensilla widely separated. In Plegadiphilus the presence of a subdivided terminal antennal segment has again been incorrectly used as a generic character (Clay, 1947; Blagoveshtschensky, 1964). In some species of this genus the pigmentation and the ridges, together with the position of the proximal sensillum and an internal break in the marginal thickening, gives the impression of one or more subdivisions (PL 3, fig. 14). In Plegadiphilus plegadis, in which this segment is short there is no indication of a division and the two sensilla are close together. In Austromenopon one species (A. affine] shows internally and externally a line of division with the sensillum just proximal to the line, others show some indication of a line of division, while others show none. It is not possible therefore to use this character as a major division in the key.

A preliminary study of the position of the sensilla and their associated setae as possible generic characters has shown considerable variation within groups of otherwise similar species. In many species the two sensilla are near each other at the distal end of the segment and their surface apertures are similar; in Bucerophagus the two sensilla are widely separated and the proximal one lies in a circular pit (PL 2, fig. n). Menacanthus stramineus has the terminal antennal segment (PL 3, fig. 13) typical of a number of species of Menacanthus from the Galliformes and Passerif ormes ; in this the distal sensillum is on the end surface of the segment with the majority of the setae, while the proximal is nearby with two or three setae which arise from a slight indentation. This differs from the elongated last antennal segment of Menopon and Amyrsidea in which there is no indentation and the two sensilla and the two lateral setae are close together on the end of the segment. However, other species of Menacanthus (that from Arborophila, for instance) in which the segment is elongate, the condition is similar to that of Menopon; and the Menacanthus from Alectoris in which the last segment is short, the sensilla are close together and the setae are merged with the group of terminal setae and no longer associated with one of the sensilla ; this arrangement is also found in many of the species parasitic on the Passeriformes. Thus, the position of the sensilla is not necessarily dependent on the length of the segment ; there is some indication that the wide separation of the sensilla

io THERESA CLAY

is associated with a tendency in the group towards subdivision of the segment. In Austromenopon the proximal sensillum may be near the distal end or at various positions in the distal part of the segment, being found nearest the base in A. affine, in which it lies near the line of division. The species of this genus probably all have two of the stout setae placed near the middle of the lateral margin of the terminal segment. It is apparent from the above survey that these characters will not provide any major divisions for the key but further studies of all the antennal characters may reveal some patterns of taxonomic interest.

4. Eyes. Wundrig (1936) has shown that the Amblycera have two ommatidia each side and these show all stages from eyes with well-developed biconvex lenses (PI. i, fig. 6) to those with no lens. As it is doubtful whether without sections it is possible to state the exact stage of development of the ommatidia, the character of ' eyes present or absent ' has not been used. The lenses are usually located on the dorsolateral margin but in Pseudomenopon and part of Eidmanniella (new genus, Ryan & Price, in press and see Clay, 1957 : 143) the eyes are more towards the centre of the head (PI. i fig. 5).

5. Mouth Parts. With the exception of the hypopharynx these are similar throughout the Menoponidae (Buckup, 1959; Haub, 1967). The maxillary palp is four-segmented, the last segment usually having two well-marked sub-terminal setae, the relative sizes of which may be a specific character (Clay, 1968, PL i, figs. 6-7). The alveoli of these setae are usually contiguous, but may be separated by a definite gap, this appearing to be a constant character in Dicteisia, Clayia and Somaphantus; both conditions are found in species of Menacanthus parasitic on the Passeriformes. In some species these setae are not apparent and perhaps merge with the terminal setae; in Cuculiphilus sens. lat. there is a third seta associated with this pair (PL 7, fig. 45). Each labial palp has five anterior setae, in Neomenopon one is fine and not apparent in all specimens. The number of setae on the prementum appears to be constant ; the lengths of one of these setae has been used as a species- group character in Actornithophilus (Clay, 1962 : 237). The postmentum usually has four setae each side; (Text-fig. 5) ; in a few genera (e.g. Myrsidea, Text-fig. 4) the most posterior seta each side is missing and in Nosopon milvus Tendeiro it is replaced by a clump of four to six small setae. The hypopharyngeal sclerites and the functionally associated epipharyngeal crest show various degrees of development which appear to be of little phylogenetic importance (Clay, 19626 : 220) : otherwise similar species may have the sclerites well-developed or reduced (Austromenopon, Clay, 1959 : 159; Myrsidea, Clay, 1966, PL 2, figs. 1-2). In Neomenopon the form of the hypopharynx is unusual and may prove to be a good generic character. The distinctive epipharyngeal organs (Buckup, 1959 : 262) appear to be present in all the Menoponidae.

Thorax

Especial attention has been paid to the thorax and legs which provide many useful generic and subgeneric characters. A detailed study has been published by Mayer (1954) and only those characters of taxonomic value will be discussed here.

KEY TO GENERA OF MENOPONIDAE n

I. Prothorax. The transverse carina of the pronotum (Text-fig, i) is apparent in all genera with the exception of Rediella ; the vertical carina shows various stages of development. In some species there is a vertical groove each side of the pronotum giving the so-called ' winged ' or ' lobed ' prothorax. The postnotum (sens. Mayer, 10,54 = mesonotum sens. Cope, 1941) in the majority of genera is a well pigmented oblong sclerite (Text-fig. 8), often distorted in mounted specimens; it may not be apparent (Numidicola) or it may be of a different shape (Ancistrona). The prosternal plate varies from being well developed to greatly reduced ; in Eidmanniella a posterior

process of the prosternal plate may be strongly or weakly sclerotized or absent. There are usually two pairs of central pronotal setae (dps) lying on or near the transverse carina, but in some species-groups (Clay, 1962 : 237) or genera (Myrsidea) they are reduced to one pair or absent. Although the number and lengths of the posterior marginal setae of the pronotum may be useful specific or species-group characters, they are not necessarily of generic importance. All species have two small central prosternal setae; additional setae may be of generic importance, but in some genera both conditions may be found (e.g. Ciconiphilus, Clayia).

2. Mesothorax. The mesonotum is developed to a greater or lesser extent, the differences not being sufficiently clear cut to use as a generic character. There are two different types of mesosternum: in the majority of genera (Text-fig. 7) the sclerite (part of the episternum) bearing the inner articulation of the leg is separated

12 THERESA CLAY

from that of the other side by a distinct mesosternal plate or by an area without a definite plate. In the other type (Myrsidea, Cuculiphilus] the mesonotum, pleura and mesosternum are fused to form a sclerotized ring round the body (Clay, 1966, PI. i, fig. 6). The anterior mesonotal setae may be four in number clustered round the distal end of the postnotum (Text-fig. 8); in some species of Odoriphila the setae of the pair each side of the postnotum lie close together and in some specimens one seta may be hidden below the other giving at low power the appearance of only two. Less commonly the outer setae may be widely separated from the inner (Actornithophilus, Text-fig. 9) or there may be only two (Myrsidea). These setae are constant in position and number within genera and form useful key characters. In addition, the mesonotum has at least one other seta each side, lateral or postero- lateral to the anterior mesonotal setae, and it is important to identify these before deciding whether there are two anterior mesonotal setae or four widely spaced ones. The centre of the mesosternum usually has four or more setae, but in some genera there are only two (Austromenopori) ; this is usually a constant character within a genus or groups of genera but in Bucerophagus there may be two or more setae.

3. Metathorax. In Myrsidea some species may have the metanotum strongly modified while in other similar species it is normal, this character therefore seems to be of little phylogenetic importance (Clay, 1966 : 331). In Clayia and at least some species of Menopon, there is a variously developed central vertical line of thickening in the anterior part of the metanotum ; however, some of the species of Menopon are based on specimens not in sufficiently good condition to say whether this thicken- ing is present, but it may prove to be a good character for these two genera. The outer seta at each end of the posterior marginal or submarginal row of metanotal setae is long or the longest of the row ; it is sometimes anterior to the rest of the row. The presence of many central setae on the metanotum may be a specific character (Actornithophilus}. There is usually a central metasternal plate with setae.

The species of Trinoton have two large thoracic sternal plates with many setae; caudad to the posterior plate is a bilobed flap appearing white in untreated specimens (PI. 5, fig. 25). Species of Eureum also have a white flap arising from what is probably the metasternum and a similar one on abdominal sternum I (PI. 5, fig. 26) and in Dennyus on the metasternum and a number of the abdominal sterna. In Trinoton the surface sculpture (PI. 5, figs. 28, 30) of the flap is similar in specimens parasitic on species belonging to five genera of the Anseriformes, but differs from that of the flaps in Eureum (PI. 5, figs. 27, 29) and Dennyus (PL 3, fig. 17). The function of these areas is unknown. Species of Trinoton also have a conspicuous white area surrounding the gular plate (PI. 5, fig. 25), but the surface sculpture is quite distinct from that of the metasternal flap (PI. 3, fig. 18).

Legs

The gross morphology of the legs is similar throughout the Menoponidae (see Mayer,

1954)-

i. Coxa. These are attached to the ventral part of the thorax except in those genera (e.g. Trinoton, Eureum) with wide sternal plates which cause the articulation

KEY TO GENERA OF MENOPONIDAE

to be more lateral; in the former genus the usual anterior prolongation of the first coxa is greatly reduced. The first coxa frequently has four or five posterior setae (Text-fig. 7.), but in certain genera (Austromenopon) or groups of genera there are more; however some of the species may have only one or two extra setae with the occasional specimen without these (in Eidmanniella) ; this character cannot therefore always be used. Those species with many setae on coxa I may also have a greater number on II and III.

2. Trochanter. Ventrally there are a number of well marked sensilla associated with two setae (Text-fig. 13), the most usual number on legs II and III being four to five, but some genera (Bonomiella) or species-groups appear to have a constant number of three. The number is of doubtful general use in the key as it is sometimes only specific (Nosopon) or there is the occasional specimen in which it varies on differ- ent legs; however, in some species groups of Menacanthus (see below, p. 18) the number is correlated to a certain extent with other characters.

3. Femur. The most important taxonomic character of this segment is the ventral chaetotaxy of the third femur. This may be in the form of patches of irregularly arranged setae (brushes, Text-fig, n) or regular rows of stout spine-like setae (combs

or ctenidia, Text-fig. 14, PI. 6, fig. 31) or a few scattered setae. The form tends to be constant throughout groups of otherwise similar species and frequently provides useful generic characters. The presence of ctenidia is a group character in the Colpocephalum-complex, but they are also found in other genera : Bucerocolpocephalum with ctenidia is otherwise similar to Bucerophagus and Chapinia without; in Piagetiella they may be present or absent in different species. Microctenia, in addition to a brush of setae, has the venter of the third femur covered with rows of comb-like outgrowths (PI. 6, fig. 32).

4. Tibia. Here again the chaetotaxy shows good taxonomic characters: the number of outer dorsal setae may form useful specific characters (Clay, 1962 : 195 ; 1966 : 334, Text-fig. 10). Many species in which there are many outer dorsal setae on tibia I, have only a few on II and III (Text-fig, n), while in others (Colpocephalum- complex) there are numerous marginal and submarginal setae in this position (PI. 6, fig. 33). Hoazineus and Heleonomus (PI. 6, fig. 34) have a row of short regular setae along the outer margin of I-III. In some genera the extra tibial setae may be present or absent (Falcomenopon, Emerson & Elbel and some species of Kurodaia) and in Osborniella the number of the tibial setae is fewer than in most species of the Colpocephalum-complex. There is considerable difference in the size and position of the terminal ventral tibial setae, but no clear distinctions could be found as they grade from relatively fine to thick spine-like setae and the distance between them shows all stages from two of the alveoli being contiguous to all four being widely spaced; it was decided that this is not a practical generic character. One genus (Piagetiella) has a tibial spur in the male.

5. Tarsus. Keler (1952, 1955) and Mayer (1954) give descriptions of this joint in some species of the Menoponidae. The tarsus comprises two segments, the proximal being small and the distal being longer and of various proportions. The pretarsus bears two claws which articulate with the well-sclerotized unguifer; the shape of the claws may be diagnostic (Bonomiella, Microctenia) . The unguitractor in the adult is in the form of two plates to which is attached the tendon-like apodeme of the retractor muscle of the claws, usually visible in specimens treated with KOH. Distally the dorsal part of the unguitractor may be elongated laterally forming two pointed processes (Neomenopon, Hohorstiella) or there may be a central comb-like area (Bucerophagus). Arising from the ventral part of the unguitractor on legs II and III is a hyaline, sometimes tuberculate process (PI. 6, fig. 35), the empodium (sens. Keler, 1952) ; the shape of this may be diagnostic (Clay, 1966) ; it may be small and is sometimes not apparent and perhaps absent. Owing to the difficulty of seeing its true form in mounted specimens, the empodium has not been used here as a taxonomic character. The first tarsal segment has a pair of setae usually hyaline and sometimes flattened; just distal to these is a pad-like lobe, the euplantula (sens, Keler, 1952). Examination of sections and of the whole structure with the light and scanning electron microscopes (PI. 7, figs. 37-41) suggests that the euplantula, in at least some species, has an outer ventral membrane covering a honey-combed area within which is a framework of vertical strands (PI. 7, fig. 41) or of vertical and hori- zontal strands giving a characteristic banded appearance (PI. 7, fig. 40). The form of these strands may be useful taxonomic characters and appears to be constant

KEY TO GENERA OF MENOPONIDAE 15

within genera and groups of genera ; all the members of the Colpocephalum-complex, for instance, have the vertical strands only; other genera not belonging to this complex also with vertical strands only are Microctenia, Hoazineus, Bonomiella and Trinoton. However, it is not possible to use this character for basic divisions in the key as there are a number of genera in which no internal striations can be seen and in Menopon it has been possible to see the striations in only some of the species. The euplantula of the second tarsal segment may be similar to that of the first (e.g. Bucerophagus) or show considerable differences : in some of the species in which euplantula I shows vertical striations only, II may be elongated to more than half the length of the tarsus with vertical striations and deeply serrated margins (e.g. Turacoeca] . In this position in Pseudomenopon there are rows of comb-like processes (PL 6, fig. 35) ; Keler (1952 : 581) suggested that this structure was homologous with euplantula II. Its presence enables the nymphs of Pseudomenopon, in which the characteristic gular plate is not developed, to be recognized generically. Examination of this area with the scanning electron microscope suggests that in some species the form of the processes may prove to be a diagnostic character. The characters of euplantula I, are probably similar on all three legs, but are usually best seen on the first leg as in mounted specimens this is more often lying in the dorsoventral plane. Pad-like structures along the inner side of the claw can be considered as pulvilli; it is not possible to say whether their degree of development is of taxonomic use. Certain other characters of the tarsus are not used owing to the difficulty of seeing them in all species or in all specimens of a species.

Abdomen

The abdomen varies greatly in shape and in those species in which the plates are not heavily sclerotized the proportions can be affected by the treatment of the speci- mens. The shape of the abdomen (together with the rest of the body) may be an adaptation to some particular factor of the environment, such as the inside of the quill (Clay, 1962 : 192; Tuff, 1967 : 247). A genus based on such characters might have been derived from different stocks (e.g. Somaphantus, see below, p. 19) and the species might have lost many of the characters showing their affinities: Rediella with a distinctive appearance, resembles Actornithophilus from the same host order in the characters of the male genitalia and the spacing of the anterior mesonotal setae.

There are six spiracle-bearing segments (III-VIII) and two (I-II) anterior to these; posteriorly to tergite VIII, there is usually a single sclerite, but some species have two. In Myrsidea females the terga may be strongly modified and tergite I not apparent or with II, greatly reduced in size; these modifications, as that of the meta- notum, seem to be no more than specific (Clay, 1966 : 331) ; members of the Colpocephalum-complex may also show tergal modifications in the female. Sternite I is usually apparent but is not so in Aegypiphilus; sternites II-VI appear as discrete central plates; VII may be fused or partly fused with the following sternites to form a subgenital plate ($ Myrsidea, Clay, 1966, fig. 26; Chapinia, both sexes) or VII may be separated from the subgenital plate (<$ Myrsidea, Clay, 1966, fig. 27;

16 THERESA CLAY

Actornithophilus, both sexes); in females of the Austromenopon species parasitic on the Procellariformes both conditions of VII are found, so that this is not necessarily a generic character. Rarely the males show modifications of the sternites as in Cacamenopon Price (sternites VI-VII) and Holomenopon goliath Clay (sternites VIII-IX). Post vulval sclerites may or may not be apparent; their chaetotaxy is sometimes a constant and generic character (Kurodaia and Nosopori).

The pleurites are usually in the form of discrete plates separated from the sternites by a membraneous area, frequently sculptured, and from the tergites by a narrow suture. In Piagetiella there may be some fusion between pleurites and tergites, either sexual or specific ; in the female Myrsidea with modified abdomens they may be reduced, absent or modified in various ways. In Comatomenopon elbeli the female has sucker-like organs on pleurite III. The inner postero ventral angle of some or all of the pleurites may be prolonged as a process (Text-fig. 26) ; this character appears to be generic in some groups (Plegadiphilus) , but is present or absent in others (Menacanthus from the Gallif ormes) . Patterns of internal thickening of the pleurites and lateral areas of the tergites may be only of specific value (in Austromenopon for instance) and are perhaps not useful generic characters.

The female anogenital region shows considerable variation: the typical anal corona may be present or absent in the species of Austromenopon parasitic on the Procellariformes (Clay & Moreby, 1967 : 158) ; some species of the Galliformes- infesting Menoponidae may also lack the typical anal corona and show various other modifications of the venter of the terminal segments; however, these are not always correlated with other characters showing differences and may not be of any phylo- genetic significance. The lateral edges of the anus may show various setae-bearing processes which appear to be constant in certain groups and generic in character (Turacoeca, Chapinia). The male genitalia may be similar throughout a genus or genera, with the occasional species being distinct (e.g. Menopon). In dealing with such males and females it does not seem reasonable or useful to erect a new genus because one sex shows some unique character, while the other sex is not separable from the rest of the group. This is illustrated by the genus Menopon in which there is much diversity of the female anogenital region and the male genitalia. In M. gallinae the terminal segment of the female abdomen is elongated, the anterior (ventral) margin of the anus is widely separated from the posterior (dorsal) margin which is terminal and beset by a row of spine- like setae; in pattens and interpositum the anal margins are not so widely separated and the anus appears more normal; in spinulosum the last segment is not elongated, the setae surrounding the anus form a triangle, the terminal margin of the abdomen does not bear the posterior anal setae, but has a number of long and short setae. The male genitalia also show considerable difference between the typical gallinae form and those with the greatly enlarged and asymmetrical parameres of the spinulosum group.

Various structures associated with the female genital chamber (Clay, 1961, fig. 7«z; Price, 1966 : 18) and the form of the bursa copulatrix (Clay, 1968 : 207) provide useful specific and sometimes generic characters. Although the presence or absence of spermatophores in the male cannot be used as a key character it is possible that their distribution within the genera of the Menoponidae may be of taxonomic

KEY TO GENERA OF MENOPONID AE 17

interest. They are probably present in all Myrsidea (Clay, 1968 : 207) and have also been seen in species belonging to other genera (e.g. Austromenopon, Ciconiphilus, Dicteisia) .

The spiracles usually open on the tergites, but in some species of Myrsidea they open on the pleurites or the membraneous area between tergite and pleurite; in Colpocephalum heterosoma the spiracles open on the pleurites in the female and on the tergites in the male (Price, 1965 : 128). Although the presence of crop teeth has been used as a generic character they seem to be present in all the Menoponidae : further dissections of suitable material are necessary to see whether they will show any taxonomic characters.

The Chaetotaxy of the A bdomen. All species examined have a small anterolateral seta each side of tergite I and II. At each end of the posterior row of seta, or somewhat submarginal to it, on tergites II-VIII is the post-spiracular seta with the two small associated setae (Clay, 1954 : 716) ; on tergite I the seta in this position is usually long and is included under the post-spiracular setae. A generally constant character is the presence or absence of a small seta laterad to each of the long outer setae on tergite I or to the post-spiracular setae on one or more tergites. Setae may be present or absent on sternite I in different species belonging to the same genus (e.g. Myrsidea}. The presence of ctenidia on one or more sternites is usually associated with similar ones on the venter of the third femur (Colpocephalum- complex); in a few genera (e.g. Piagetiella, Eomenopon) there may be abdominal ctenidia but none on the femur. The position and the number and size of the setae in the sternal brushes may be a useful generic character.

Part II

KEY INTRODUCTION

The key includes all the generally recognized genera and subgenera (with the exception of those belonging to the Colpocephalum-complex and the Menacanthus- complex) even where it is considered that there is no advantage in the recognition of some of these taxa. The Colpocephalum-complex, as interpreted here, comprises all those genera with ctenidia on the venter of the 3rd femur with the exception of Cuculiphilus sens, lat., Bucerocolpocephalum, Piagetiella, Turacoeca and Odoriphila; it is possible that the last genus should be included. Dicteisia may belong to the complex but is separated in the key. Other characters common to the complex are the contiguous alveoli of head setae 26 and 27 ; setae 24 and 25 are usually minute to short, in a few species they are longer, but do not reach to the end of the pronotum; the presence of a vertical patch of submarginal setae on the temples; head sensilla c. usually present; four anterior mesonotal setae; usually more than two central mesosternal setae; mesosternum normal; tibiae II-III usually with submarginal patch or row of outer distal dorsal setae, euplantula with vertical striations only; ctenidia on one or more sternites. Baiter (personal communication and see Baiter, 1968) has found that the operculum of the egg opens diagonally in species of the complex from the Galliformes, Falconiformes, Ciconiiformes, Pelecaniformes,

THERESA CLAY

Psittaciformes and Passerif ormes ; in addition this character is found in the eggs of Nosopon, but not of Osborniella or any of the species of Ciconiphilus examined.

The Menacanthus-complex comprises Menacanthus, Amyrsidea, Argimenopon Eichler, Cracimenopon Carriker and Desumenopon Carriker, its species being parasitic mainly on the Galliformes and Passeriformes. Divisions within this complex are dependent on which characters are used, these include : width of head and form of its dorsolateral margin; form of gular and prosternal plates; development of the hypopharynx; presence of postpalpal processes; shape of the antennal segments; number of setae on coxa I; number and position of the sternal brushes of setae; presence of sternal spiniform setae; position of the post-spiracular setae on tergites I-II; degree of development of the internal tergal and pleural thickening; presence of a prolongation of the posteroventral corner of the pleurites; terminal segments of the female abdomen and the male genitalia. A distinctive species group (including

the type species of Menacanthus) parasitic on the Passeriformes has long postpalpal processes; an approximately rectangular, strongly pigmented gular plate with or without a central thinner area; two to four setae anterior to the subocular comb row; three ventral sensilla on the trochanter; and spiniform setae laterally on the posterior margin of the sternites. Another group (e.g. M. alaudae), also parasitic on the Passeriformes, has short postpalpal processes; gular plate various; four to five setae anterior to the comb row, two of which are long; four ventral sensilla on the trochanter; and no spiniform setae on the sternites. This group, in addition to being found on the Passeriformes, is found on the Picidae (the species may have

KEY TO GENERA OF MENOPONIDAE 19

fewer setae anterior to the comb row and rather longer head processes) and on the Galliformes (length of processes varies). Amongst other species parasitic on the Passeriformes are those showing characters intermediate between the two groups: a species from one of the Parulidae has the characters of the first group but the post- palpal processes are small ; Menacanthus crateropus has shorter processes than in the first group, no sternal spiniform setae, three setae anterior to the comb row and three sensilla on the trochanter; the species on Salpinctes (Troglodytidae) has small processes, four to five setae anterior to the comb row; no sternal spiniform setae and three sensilla on the trochanter. Elsewhere (Hopkins & Clay, 1955 : 180) the possibility has been discussed that some of the species of Menacanthus from the Galliformes are nearer to species of Amyrsidea than to other species included in Menacanthus, being separable only by the presence of the postpalpal process.

It is possible that Menopon, Clayia and Somaphantus also belong to the Mena- canthus-complex. It has already been suggested that the species of Somaphantus might be derived from more than one Galliformes-infesting stock, the similarity being due to the environment of the quill inside which they live. This would explain some of the differences between the species such as the position of the post-spiracular setae and chaetotaxy of the head ; spencei Emerson is the only species with a circular structure within the genital chamber. S. kingi Emerson and Price (no specimens seen) resembles other species of Somaphantus in the tubular abdomen, but differs in the number of the sternal brushes and does not have the typical Somaphantus head; its affinities lie perhaps with such species as Amyrsidea elbeli Emerson and Stojanovich; the female of this latter species resembles Menopon gallinae in the prolongation of the last segment and the form of the anus. S. kingi is not included in Somaphantus in the key.

These genera of Menoponidae found on the Galliformes are possibly derivatives from a single ancestral stock perhaps parasitic on an early Galliformes stock; the evolution of the parasites may have included not only divergence with the divergence of their hosts but also perhaps secondary infestations from host to host at the specific and supra-specific level.

Notes

Illustrations. In preparation of this paper use has been made of the Stereoscan scanning electron microscope (S.E.M.) and this has made possible the elucidation of certain structures. Although most of these can be seen with the light microscope, especially when once identified and elucidated with the scanning electron microscope, photographs taken with this latter instrument are the most accurate method of representing small structures.

In order to save space authors of genera and species appearing in Hopkins & Clay, 1952, 1953, 1955 are not cited and only those references which do not appear in Keler, 1960 are listed.

SYNOPSIS

An alphabetical catalogue is given of the 156 species and infraspecific taxa of Tachinidae described by N. Baranov, with an account of all located type-material on which the names are based. Sixty-one lectotypes are newly designated. Manuscript names of Baranov that have appeared in print, some of which have been validated by later authors, are enumerated and briefly discussed. The references given include a complete bibliography of Baranov's papers on Tachinidae.

INTRODUCTION

BETWEEN 1926 and 1942 the Slav dipterist N. Baranov — who was born in Russia but worked mainly in Jugoslavia — published a series of papers on the taxonomy of Calyptrate Diptera, many of them in rather inaccessible Yugoslav journals. In these he described and named a total of 26 genera, one subgenus, 183 species, and 17 infraspecific taxa, distributed as follows : 19 genera, one subgenus, and 145 species (plus n infraspecific taxa) of Tachinidae ; 6 genera and 32 species (plus 6 infraspecific taxa) of Sarcophagidae ; one genus and 5 species of Calliphoridae ; and one species of the Muscidae. Our present paper is concerned only with the Tachinidae, the vast majority of which were described from the Oriental and Australasian Regions ; Baranov described only a few taxa from the Palaearctic Region, and none from Africa or the New World. For each species-group taxon we give an account of all the type-material that we have been able to locate, but we have not attempted to assign the species to currently recognized genera or to investi- gate possible synonymy (this will be done by Crosskey at a later stage for the systematic catalogues of Oriental and Australasian Tachinidae in preparation). The paper is presented in two parts : Part I contains the properly proposed and

30 C. W. SABROSKY & R. W. CROSSKEY

available species-group names of Baranov, and Part II contains the 32 manuscript names of Baranov that have appeared in print ; of the latter a few were cited in synonymy by Baranov himself, but most were published by someone else. Occasionally the other authors have given some descriptive matter and have thus made some of the Baranov manuscript names nomenclaturally available under the International Code of Zoological Nomenclature, 1961, so that authorship must be credited to them (under Article 10) and not to Baranov. However, as the names appear in the literature credited to Baranov it is desirable to account for them in the present work. In addition to the names given in Part II we have discovered, during preparation of this paper, a number of specimens in different museum collections that are sometimes labelled as types and bear manuscript names of Baranov that have never (so far as we can trace) appeared in print ; at least 23 such names are known to us, but as they are unpublished manuscript names only we are not recording them.

All names given in Parts I and II are listed alphabetically in their original com- binations. For each nominal species-group taxon in Part I the entry is arranged to show the following information in the sequence indicated : —

Name ; author ; date and page reference of original publication ; status and sex of primary type ; authority for lectotype designation (if relevant) ; data of primary type (when available in the sequence : locality, altitude, date of collection, host information, name of collector) ; type-depository ; location of genitalia in the case of male primary types (as ' genitalia in situ ' or ' geni- talia on slide ').

Number and sex of paralectotypes or paratypes, with data and depository information as for primary types. (It has not been considered necessary, however, to specify whether male genitalia are present on or removed from paralectotypes or paratypes.)

Explanatory comments or annotations if considered necessary. The type data as we record them do not necessarily conform exactly in spelling or sequence with the data labels. Geographical names are given as on the data labels (e.g. Buitenzorg and not the modern equivalent of Bogor), except for the correction of obvious misspelling and a modern terminology for sovereign states (e.g. Thailand instead of Siam). The major islands of the former Dutch East Indies are shown by their well known names such as Celebes, and not by their very new names. The names of plants and insects cited in the host information are given as on the data labels and have not been checked for their modern equivalents. Collectors' names are given with full initials when these are known, even if not all are shown on the data labels (e.g. R. J. A. W. Lever instead of R. A. Lever). Baranov spelt his own name with either a terminal ' v ' or ' ff ' in his papers on Tachinidae, but almost always used the ' ff ' ending on his type labels and deter- mination labels ; we have not differentiated in this paper but have adopted the ' v ' ending throughout, except when quoting his labels.

Much of Baranov's type-material from H. Sauter's collecting in Formosa is labelled either ' Kankau ' or ' Kankau (Koshun) ' ; we have uniformly used both names as the village of Kankau (now Koko) is in the district of Koshun, with the

co-ordinates 22° oo' N. and 120° 49' E. (locality traced from Gazetteer (No. 13) Formosa (Taiwan), U.S. Navy Department, Hydrographic Office Publication No. 393. 139 PP-. 1944)-

Recognition of type-material and interpretation of its status are often difficult with Baranov species, especially in the face of variant usage in both practice and publication. Certain conclusions need some discussion.

Baranov consistently placed an identification label in his handwriting on each specimen (we interpret the very few exceptions found as due to loss of labels), usually with ' n.sp. N. Baranoff ' after the specific name. However, sometimes some of such material was not mentioned in the original publication. We have felt obliged to exclude from the type-series all material that differs from that speci- fied in the published data except where there seems to be a reasonable explanation for a discrepancy, such as a typographical error or a misread label. All such instances are annotated.

Baranov did not use the term ' holotype ' in publication or on labels, although his ' Typus ' is sometimes that. Usually ' Typus ' was not mentioned in publication, however. Some series have a ' Typus <$ ' and a ' Typus $ ' and ' Cotypen ', but some have only ' Cotypen ' so far as we can discover. Occasional examples are labelled ' Paratypisches Exemplar '. We have regarded all such series as consisting of syntypes and have designated lectotypes when not already designated ; usually, when available, we have selected Baranov's ' Typus <$ ' as the lectotype. Each lectotype has been clearly labelled as such, and 61 lectotypes are newly designated.

Hennig (1941) mentioned many of Baranov's specimens in his list of the Diptera of Formosa, but he was only a recorder of data on specimens in the Deutsches Entomologisches Institut collection and not a reviser or designator of lectotypes. His use of ' Typus ' merely indicates the presence of one specimen, as opposed to ' Typen ' for more than one ; this is clear from his multiple use of ' Typus ' under those species where there were single specimens from two or more localities. Townsend (1934-1942, Manual of Myiology, 12 Parts, Itaquaquecetuba) has some- times cited ' Ht [i.e. holotype] in DEI ', but he did not see Baranov material or label specimens, and apparently he listed ' holotypes ' by assumption from the literature. If there is only one male in the series, in such a case, we have accepted, albeit reluctantly, Townsend's action as fixation of the lectotype. However, when two or more syntypes of the designated sex are available Townsend's published designation is not an ultimate restriction to a single specimen and we have then designated a lectotype.

Designation of a lectotype automatically converts all other syntypes into para- lectotypes, even if they are never labelled as such and even if not conspecific with the lectotype. In Baranov's work mixed type-series rarely occur and we have recorded the few cases known to us. We have labelled all available syntypes remaining after lectotype designation as paralectotypes, even for mixed series. We should, however, comment here that there may be other paralectotypes that we have not seen, and indeed we consider this probable for the following reason : many of the species described by Baranov from an unstated number of specimens

32 C. W. SABROSKY & R. W. CROSSKEY

were based upon material submitted to him for identification by the Imperial (now Commonwealth) Institute of Entomology, and in the years from 1932 until 1940 he received all the material of Oriental Tachinidae coming to this Institute from British-administered territories ; this often consisted of series of reared specimens sent by departments of agriculture or forestry in India, Ceylon, Burma, Malaya, Solomon Islands, or Fiji, and undoubtedly some original specimens were returned (after identification and description) to collections in the territories of origin. It is therefore likely that some insect collections in the countries mentioned still contain specimens that are paralectotypes of species described by Baranov.

The status of certain material is sometimes difficult to determine, and we have decided each case individually. For some species an expression in the original publication such as ' Weitere Exemplare ' seems to be merely a way of recording additional type-material and we have accepted these specimens as syntypes. In other cases it seems clear to us from Baranov's words that the additional specimens cited did not form part of his type-series, nor was the description based upon them. All such cases have been annotated. Should later differences of opinion arise our lectotype designations will nevertheless stand, and any other specimens later believed to be part of the type-series will be additional paralectotypes.

Some comment is necessary on the slide preparations of male genitalia which exist in several museum collections and associate with pinned type-specimens. Baranov was one of the first workers on the Tachinidae to recognize the great value of the male genitalia for distinguishing between closely allied species, especially among the Exoristine and Goniine forms in which few other really reliable characters exist, and he frequently published figures of the genitalia drawn from permanent slide-mounts. Many of Baranov's male type-specimens have had the whole hypo- pygium neatly extracted and mounted on labelled glass slides, and it is usually possible to associate slides of the genitalia with the actual specimens from which they were made. In the text for each nominal taxon listed in Part I of the present work we have indicated whether the genitalia of the male primary type are in situ on the specimen or separately slide-mounted ; we have been able to locate the associated slides for almost all primary types from which they have been removed, but there are a very few (indicated where necessary) for which the slide-mount appears to be lost. In the course of our work it was found that several slides were still among Baranov's own collection (now in the U.S. National Museum) although the associated type-specimens were correctly located elsewhere, and in these cases the slides have now been sent to the museum collections in which the type-specimens themselves are deposited. The statement ' genitalia on slide ' given in the text for any holotype or lectotype therefore implies that the slide will be found in the same collection as the pinned primary type.

Baranov's type-material is scattered among several museum collections. The

bulk of it is in London, Eberswalde (East Germany) and Washington D.C., but

some type-specimens are in Bogor (Indonesia), Ottawa, Warsaw, Amsterdam,

Dresden, and Brisbane. Specimens mentioned by Baranov as being located in the

museum at Stettin are now in the Zoological Institute of the Polish Academy of Sciences, Warsaw. In some of his papers Baranov has mentioned specimens in the Instituut voor Plantenziekten, Buitenzorg (now the Central Institute for Agricultural Research, Bogor) but from a detailed list of Tachinidae in the collection of that Institute (very kindly sent to us by Dr. Ida Njoman Oka : see Acknowledgements) it appears that no actual syntype specimens are present there. There are, however, several holotype, lectotype and paralectotype specimens in the Museum Zoologicum Bogoriense. Specimens mentioned by Baranov as belonging to the Imperial Institute of Entomology are in the collection of the British Museum (Natural History). To condense the text we have used the following abbreviations for the main type-depositories :

BMNH British Museum (Natural History), London.

CNC Canadian National Collection, Ottawa.

DEI Deutsches Entomologisches Institut, Eberswalde.

IZPAN Instytut Zoologiczny, Polska Akademia Nauk, Warsaw.

MZ Museum Zoologicum Bogoriense, Bogor, Indonesia.

USNM United States National Museum, Washington, D.C.

Baranov's own collection was acquired by the United States National Museum in 1960, and the depository abbreviation USNM is applied to material that correctly belonged in the former Baranov collection.

ACKNOWLEDGEMENTS

It gives us much pleasure to acknowledge the helpfulness and generosity of the colleagues who have assisted us with the loan of type-specimens or with valuable information in reply to our enquiries.

We are especially indebted to Dr. Gunther Morge for the loan of the very large number of Baranov types, together with genitalia slides, from the collection of the Deutsches Entomologisches Institut, and to Dr. S. Somadikarta for the loan of types from the Museum Zoologicum Bogoriense, Indonesia.

For confirmation of the presence of types in other collections, and for details of their data, we are most grateful to Dr. A. Draber-Monko (Zoological Institute, Polish Academy of Sciences, Warsaw), Dr. W. Ellis (Zoological Museum, Amsterdam), Dr. R. Hertel (Staatliches Museum fur Tierkunde, Dresden), and to Mr. G. E. Shewell and Dr. D. M. Wood (Entomology Research Institute, Canadian Department of Agriculture, Ottawa). Dr. L. P. Mesnil kindly furnished us with information on a few types from the DEI collection that are temporarily in his care at the Commonwealth Institute of Biological Control, Delemont, Switzerland, and Dr. J. d'Aguilar kindly confirmed that the missing holotype of Voria edentata was not on loan to him.

We thank Dr. D. Mikacic, Department of Parasitology and Parasitic Diseases, Faculty of Veterinary Medicine, University of Zagreb, for confirming that so far as he can trace there are now no Baranov type-specimens in Zagreb, Yugoslavia, none can be found in the Naturhistorisches Museum, Vienna (to which it was

34 C. W. SABROSKY & R. W. CROSSKEY

thought that some material could have been moved from Zagreb during the last war).

Dr. Ida Njoman Oka provided us with a most valuable list of the Tachinidae identified by Baranov that are in the collection of the Central Agricultural Research Institute (Lembaga Pusat Penelitian Pertanian) in Bogor, Indonesia, and we take this opportunity of expressing our particular appreciation of this in view of the large amount of work that its preparation entailed.

Asiocarcelia pseudocaudata Baranov, 19340" : 4°7- Holotype <$, FORMOSA : Tainan, iv.igio (H. Sauter) (USNM). Genitalia on slide.

The holotype is labelled by Baranov as ' Carcelia pseudocaudata n.sp. N. Baranoff TYPUS '.

Bactromyia crassiseta Baranov, 19386 : 409. Holotype $, AUSTRALIA : Queensland, Biloela [publ. as Biloala], 14.41.1927 (G. A. Currie) (BMNH).

Bactromyia fransseni Baranov, 19340 : 45- Lectotype $, by designation of Crosskey (1963 : 6), CEYLON : Peradeniya, 8.viii.i928, pupal par. of Psara bipunctalis (J. C. Hutson) (BMNH). Genitalia on slide.

Paralectotypes : 2 $, 7 $, same data as lectotype (BMNH). i $, same data as lectotype (USNM). i $, CEYLON : Peradeniya, 2i.vi.i9ig, ex Nacoleia annubilala (J. C.

Baranov annotated the original description as follows : ' Originalfundort Java. Cotypus <J in der Sammlung des Instituuts voor Plantenziekten in Buitenzorg. Cotypus $ in meiner Sammlung ' ; nevertheless we consider that the material listed before the description is part of the syntype series, as there is no evidence to show that the description has not been partly based upon it, and we hold Crosskey 's (1963 : 6) designation of a lectotype from Ceylon as valid. The female ' Cotypus ' from Java alluded to by Baranov as in his collection is now in the USNM (see list of paralectotypes above) and in fact bears a Baranov label reading ' Allotypus $ '. We have been unable to confirm whether Baranov's male ' Cotypus ' from Java with the date 29.iii.i932 is in the collection at Bogor (formerly Buitenzorg), but the slide of the male genitalia from this specimen is at present in the USNM collection.

Bactromyia fransseni solomonica Baranov, 19380 : 170. LECTOTYPE <$, SOLOMON ISLANDS : Russell Island, vi.ig32 (R. J. A. W. Lever) (BMNH). Genitalia on slide.

Paralectotype : i $, same data as lectotype (USNM).

There was no evidence from the original description of solomonica that Baranov had more than one specimen, and Crosskey (1963 : 7) assumed that the single specimen in the BMNH collection was the holotype. It has now been found that Baranov's collection in the USNM contains a second specimen with identical data, so that present designation of a lectotype is necessary (see above) . The lectotype is in poor condition with loss of one wing, several legs, and the abdomen is separately card-mounted ; Baranov's original label on the lectotype reads ' solomonicola ', but solomonica was the published spelling.

Bezziomyiobia nigripes Baranov, 19380 : 172. Holotype $, SOLOMON ISLANDS : Tulagi, 16 [publ. as 6]. xii.i934 (R- J- A. W. Lever) (BMNH).

Blepharipoda eutachinoides Baranov, 19320 : 92. LECTOTYPE <J, FORMOSA : Sokutsu, ix.i9i2 (H. Sauter) (DEI). Genitalia on slide.

Paralectotype : i <$, same data as lectotype (USNM).

Cadurcia leefmansi Baranov, 1933 : 153. Holotype (as ' Protograph ', figured specimen) (J, JAVA : Buitenzorg, ex caterpillar of Brachartona catoxantha Hampson (Leefmans) (probably lost, whereabouts not traced, but slide-mount of genitalia in USNM).

Paratypes : i <£, i $, same data as holotype (USNM). i $, same data as holotype (MZ, Bogor) .

This species was described from five specimens of both sexes (number of each not specified), of which one male was referred to by Baranov as the ' Protograph ' and the other four as ' Cotypen '. The unfamiliar term ' protograph ' as used by Baranov is clearly equivalent to holotype and refers to the single specimen from which the illustration of the male genitalia was drawn (after removal of the hypopygium) ; this specimen was stated by Baranov to be in the Instituut voor Plantenziekten in Buitenzorg, Java (now the Lembaga Pusat Penelitian Pertanian, Bogor) and the slide preparation of its genitalia in his own collection. The ' Protograph ', i.e. holotype, specimen cannot now be found in this institution in Bogor, or at the Museum Zoologicum Bogoriense, and it is not among Baranov's own collection, and must be considered probably lost ; but the slide of the genitalia, labelled ' Protograph ', from Baranov's own collection, is present in the U.S. National Museum.

Of the ' Cotypen ' specimens (i.e. paratypes) two are in USNM collection and one (a com- plete but teneral male) has been located in the Museum Zoologicum Bogoriense. Baranov noted in the original publication that C. leefmansi had earlier been identified by Bezzi as ' Degeeria albiceps Macquart ', and the paratype specimens in USNM and MZ all bear this name as well as Baranov's original labels.

In an earlier work Crosskey (1963) referred to four syntypes of Cadurcia leefmansi in error : as noted above, there were five original specimens of which one is acceptable as holotype.

Cadurcia vanderwulpi Baranov, 19386 : 410. Holotype $, INDIA : U. P., Haldwani, Chakrata Range, 4 [publ. as i8].vi.i93o, ex pupa of Hapalia machaeralis (S. N. Chatterjee) (BMNH).

Baranov published the name vanderwulpi as a ' nom. nov. ' for the misidentified ' Argyro- phylax zetterstedti, v. d. Wp., nee. B. B., nee Villeneuve '. It is not a replacement name for a junior homonym, but is an available name for a nominal species based upon the three-line description given by Baranov ; the sole cited specimen (data above) is the holotype.

Calotheresia (Calotheresiopsis) orientalis Baranov, 19321? : 214. Holotype $, CELEBES : Tomboekoe [publ. as Tomboegoe] (USNM). Genitalia on slide.

Carcelia aberrans Baranov, 19310 : 27. Holotype $, FORMOSA : Koshun, Kankau, 7-viii.i9i2 (H. Sauter) (DEI). Genitalia on slide.

The Baranov collection in USNM contains a male specimen of caudatella labelled by Baranov as ' n.sp. ', but it has the data ' Karimen Djawa, v.ig26 (Dammerman) ' (not cited in the original publication) and is not a type-specimen.

Carcelia distincta Baranov, 19310 : 32. Holotype <$, FORMOSA : Sokutsu, ix.i9i2 (H. Sauter) (DEI). Genitalia on slide.

At the time of writing the holotype is temporarily in the collection of Dr. L. P. Mesnil, at Delemont, Switzerland.

Baranov described octava in two forms, A and B. The lectotype and all above-listed paralectotypes are of ' form A ' and are so labelled by Baranov. The DEI collection contains in addition one paralectotype of ' form B ', labelled as such by Baranov, and with the same data as the lectotype, except for the date viii.i9i2.

Carcelia pilosa Baranov, 19310 : 29. LECTOTYPE $, JUGOSLAVIA : Bosnia, Sarajevo (USNM). Genitalia on slide.

We have not seen the second original syntype, locality unknown to us, stated by Baranov to be in the Riedel collection, but Mesnil (1944 : 29) has noted that it is very close to Carcelia excisa (Fallen).

In the original description Baranov treated Carcelia prima as two forms, prima A in which there are two reclinate orbital setae and prima B in which there is only one reclinate orbital seta ; he did not state the number of specimens of either form, but the specimens we have located and recorded above must represent most of the original syntype material for both forms. In a later paper Baranov (19340" : 396-39?) considered A and B to be distinct species and he retained the name prima for the species represented by B ; we have therefore selected a specimen of form B as the lectotype of Carcelia prima (see above). Baranov (19340") treated his form A in synonymy with Eucarcelia kockiana (Townsend), but we are not able to say at this time whether this is correct.

We have not seen the specimen of prima A from Tsingtau cited by Baranov in the original publication, but this will be another paralectotype if it is ever located.

It should be noted that the female paralectotype from Taihorinsho in the DEI collection is wrongly associated and has the hind coxa bristled and a ventral submedian seta on the middle tibia (in all the other material the hind coxa is bare and the mid tibia lacks a v sub- median seta) . The lectotype, all paralectotypes from prima B, and most of the paralectotypes from prima A, have the basicosta a clear yellow-orange colour, but in some of the paralecto- types of prima A the basicosta is darker and distinctly browned on the fore margin (so it is possible that prima A paralectotypes could be an admixture of specimens from two very closely allied species). The lectotype and paralectotypes of prima B have only one pair of reclinate orbital setae, and the paralectotypes of prima A have two pairs of reclinate orbital setae, but it is not fully certain, despite Baranov's (19340") treatment, whether this is evidence that two species are involved.

Carcelia quarta Baranov, 193 10 : 33. Holotype <J, FORMOSA : Gebiet des Sh'shastammes, v-vi.igi2 (H. Sauter) (DEI). Genitalia on slide.

Carcelia quinta Baranov, 19310 : 33. LECTOTYPE £, FORMOSA : Koshun, Kankau, ix.i9i2 (H. Sauter) (DEI). Genitalia in situ. Lectotype designated from ' quinta A ', see discussion below.

Baranov described quinta in two forms, A & B, denned by differences in the relative widths of the interfrontal area and parafrontals ; the number of original specimens of each form was not stated, but so far as we can tell the four specimens cited above form the complete type-series for both forms. The lectotype and each of the paralectotypes in USNM and BMNH is labelled by Baranov as ' quinta A ', and the paralectotype in DEI collection is labelled by Baranov as ' quinta B '.

The Baranov collection in USNM contains two males from Formosa (no other data) that are here not considered to be part of the type-series. After listing the type, Baranov stated ' Auch von Formosa mir bekannt ', without giving details and without clearly including the specimens in his type-series.

Baranov (i934c : 475), in a second paper in the same month (August 1934), published records of four males of D. solomonensis, giving two localities not mentioned for the original series ; these males appear to be additional material, and are presumed to be not type- material. In this second paper (Baranov, 1934^) there is a figure of the male genitalia, but no diagnosis in words, and under the International Code of Zoological Nomenclature, 1961 (Article i3a (i)) the name solomonensis would be nomenclaturally unavailable from this second paper even if it should be found to be the earlier of the two publications.

Beeson & Chatter] ee (1935 : 173) had already published this name, prior to Baranov's description, and had given a figure of the entire fly together with an account of the life history, but these authors gave no description and the name is therefore nomenclaturally unavailable from Beeson & Chatterjee (1935) under Article i3a (i) of the International Code of Zoological Nomenclature, 1961.

We accept the two males from Takao (in USNM collection) as syntypes as they are labelled as ' n.sp.

We accept Baranov's ' cotypus ' specimens from Kavadar with the date 5.vii.iQ27 as paralectotypes, but it should be noted that in the original publication Baranov cited this date for specimens from Skoplje : we consider that Baranov probably made a slight error in recording the data. Baranov noted specimens from Belje (22.vi.-5.vii.i923), Bitol (9.ix. 1928) and Struga (y.ix.i928) in the original publication but none of these have been located ; they will be additional paralectotypes when found.

There was no evidence from the original description of bezzii that Baranov had more than one specimen, and Crosskey (19676 : 103) cited the specimen in BMNH collection as holo- type. It has now been found that Baranov's collection in USNM contains a second specimen with identical data, so that present designation of a lectotype is necessary (see above).

Paralectotype : i <$, JAVA : Idjen, Blawan, 950 m, vi.i924 (Dammerman) (USNM).

In the original description Baranov cited the locality simply as ' Java ' without additional data, and stated ' Typus im Zoologischen Museum in Buitenzorg '. The collection of the Zoological Museum in Bogor contains one male specimen but it is actually labelled as ' Para- typus ', and the male specimen in USNM collection is labelled as ' Typus '; however, the slide preparation of the genitalia from the USNM collection is labelled as ' Cotypus ' and not as ' Typus '. We consider that the two males are syn types, and the specimen in MZ, Bogor has been designated as lectotype to conform with Baranov 's statement of the depository.

The USNM collection contains a female specimen with the same data as the lectotype (except that the date is given ambiguously as both iii and vi), but as only the male sex was mentioned in the description and as the female specimen is labelled as ' aureifrons mihi N. Baranoff ' (i.e. not with an original ' n.sp. ' label) we consider that it is not an original syntype.

Baranov (19380! : 171) later recorded specimens from the Solomon Islands as Eutachina quadrisetosa Bar. and compared them with Formosan quadrisetosa, but this is a lapsus and clearly an erroneous subsequent spelling of quadriseta Baranov.

Eutachina rusticella Baranov, 1936 : 108. LECTOTYPE <$, FORMOSA : Takao, 28. xi. 1907 (H. Sauter) (IZPAN, Warsaw). Genitalia on slide.

Paralectotypes: i Q\ same data as lectotype (USNM) . i $, SUMATRA: [no other locality data] 8.ix.i93o (USNM : genitalia preparation only).

In the original description Baranov recorded ' Sumatra (Imperial Institute of Entomology) ' among the original material seen, and there must therefore have been at least one syntype from Sumatra. We have been unable to locate a complete specimen from Sumatra, but the Baranov collection in USNM contains a slide preparation of the male genitalia of a specimen of rusticella labelled by Baranov as from Sumatra, with the date 8.ix.i93o, and with the abbreviated words ' Imper. Inst. ', and we consider this slide to confirm that there was at least a male syntype from Sumatra ; we therefore record it above as one of the paralectotypes. Tachinid material handled by Baranov from the Imperial (now Commonwealth) Institute of Entomology was normally deposited in the British Museum (Natural History) collection or returned to the sender, but in this case (as the body of the syntype has not been found) the genitalia slide preparation is retained in the USNM collection, whence it can be returned if the associated specimen is found.

The USNM collection also contains a male specimen of rusticella from the same locality as the lectotype, but with the date 6.xii.i9O7 ; this date does not fit with the original published data and the specimen is considered not to be a syntype.

In the original publication Baranov mentioned a total of five specimens (2 <$, 3 9) but did not mention the month date ' xi '. We have traced a total of six specimens (see above), two of which have the month date ' xi ' ; all are labelled as ' n.sp. ' by Baranov and we consider all to be original syntypes. We consider the discrepancies to be due to inadvertent lapse by Baranov in recording the material.

Although Baranov headed the original description of quadrimaculata with a ' 6* ' sex symbol only, we have accepted two female specimens as part of the original syntype series and have listed them as paralectotypes above. Our reasons for this are, firstly, that these females have similar data to the males and bear Baranov's usual type of ' n.sp. ' label ; and, secondly, that elsewhere in the same paper Baranov has introduced a note on the ' Weibchen ' in descriptions headed ' 6* ' only, in such a way that the descriptions appear to be based only on the male but were actually drawn from both sexes. We therefore infer that Baranov had both sexes before him but that the symbol ' $ ' was inadvertently omitted.

In addition to the two specimens above mentioned the USNM collection contains a male specimen with data ' Sejeme, Croatia, 2. viii. 1929 ', but this is not considered to be an original syntype ; Baranov's description mentions only specimens with month dates ' VI.— VII.' and collection in August would probably be too late for citation of the material in a paper published in the same year.

There is a female specimen in the USNM collection labelled as new species but with the data ' Dammerman N.O. Soemba, Kambera, 4.111.1925 '. No such specimen is mentioned in the original description and it is not a syntype.

Paralectotypes : i <$, same data as lectotype (USNM). i o*> i ?, same data as lectotype, except dates 8.vi. and 17^1.1930 respectively (BMNH).

Although Baranov headed the original description of atkinsoni with a ' <$ ' sex symbol only, we have accepted one female specimen as part of the original syntype series and have listed it above as a paralectotype. Our reasons for this are, firstly, that the specimen has identical data with the lectotype (except for slight difference in date) and bears the usual type of Baranov ' n.sp. ' label ; and, secondly, that elsewhere in the same paper Baranov has introduced a note on the ' Weibchen ' in descriptions headed ' $ ' only, in such a way that the descriptions appear to be based only on the male but were actually drawn from both sexes. We therefore infer that Baranov almost certainly had the female before him at the time of description, and accept it as an original syntype (see similar situation discussed under Exorista quadrimaculata Baranov) .

The USNM collection contains a specimen of this species bearing the label ' Ilia mirabilis g.n. sp.n. N. Baranoff ' in Baranov's writing, but it is not mentioned in the original publica- tion and is not a type-specimen. The data are : $, SOLOMON ISLANDS : Savo Island, Tasimania, 500-700 ft., 24^1.1935 (R. J. A. W. Lever).

In addition the following paralectotypes that are not conspecific with the lecto- type (see discussion) : 2 $, FORMOSA : Tainan, iv.igio (H. Sauter) (DEI & USNM).

It is not clear from the format in the original publication how many specimens were avail- able to Baranov at the time of description, for he cited only the following information : ' FORMOSA : einige Exemplare im Deutschen Entomologischen Institut in Berlin- Dahlem. — Tainan, iv.igio und Takao, xii.igo7 (H. Sauter) ; Museum in Stettin '. Normally this punctuation would indicate in Baranov's work that he saw some specimens in the DEI collection from unspecified localities, and also specimens in Stettin from Tainan and Takao ; in fact the Stettin collection (now in Warsaw) contains specimens only from Takao, and the DEI collection contains specimens from Tainan and Toa Tsui Kutsu (a locality not actually cited by Baranov at the time of description, but recorded later by Hennig, 1941 : 198 as the locality of one of Baranov's types). In addition there are specimens from Baranov's own collection that are now in the USNM or BMNH collections, and altogether we have located seven specimens (all males) that we consider to be original syntypes and have listed

above ; these include the specimen from Toa Tsui Kutsu which we consider to be one of ' einige Exemplare ', and have selected as lectotype.

It is important to note that hemimacquartioides type-material is mixed, and consists of two very closely similar species : in one species the male head is without proclinate orbital setae and the scutellum has small upwardly-directed crossed apical setae, and in the second species the male head has two pairs of proclinate orbital setae and the scutellum lacks apical setae. The latter species, because of the proclinate orbital setae, has the male head extremely like that of the normal female Tachinid in which these setae are present, and we think that Baranov cited ' $ ' as well as ' £ ' at the head of the description of hemimacquartioides in error (as we have found no female specimens among the syn types). In the original descrip- tion Baranov wrote of the scutellum that ' Die gekreuzten, aufgerichteten Apikalborsten sind fein ', and we have therefore selected the lectotype from specimens showing this charac- ter (i.e. from the species in which the male lacks the proclinate orbital setae). The specimens in which the male possesses proclinate orbital setae are both from the Tainan locality cited in the original description ; one is in the DEI collection and the other in USNM (see above) .

The lectotype lacks the genitalia and the slide preparation has not been located. How- ever, it may be noted that the conspecific male paralectotypes from Takao in the USNM and BMNH collections are both intact, and that although both males from Takao in the IZPAN collection at Warsaw are without genitalia there is a slide preparation in that collec- tion that must associate with one of the two specimens.

Paralectotypes : 2 $, same data as lectotype, but with month date ' i ' (USNM). 4 $, FORMOSA : Kosempo, v.igi2 (H. Sauter) (DEI, two ; BMNH ; USNM).

Baranov's original description reads as though all syntypes (number unstated) of both sexes were from Kosempo, but the specimen bearing his red handwritten ' Typus ' label (here designated as lectotype) has no locality data other than ' Formosa I. ' ; only the female syntypes have the locality Kosempo on the data labels. Since there is more than one male, and none from Kosempo that we have been able to locate, Townsend's (1938 : 41) citation of ' Ht male ' does not provide a valid fixation of a lectotype.

The original material consists of one male and one female syntype, of which Townsend (1939 : 43) cited the male as ' Ht ' (= holotype) and the female as ' At ' (— allotype). Townsend's action restricts the name to a single primary type, and we accept it as providing valid fixation of a lectotype.

TYPE-MATERIAL OF TACHINIDAE 47

In the original publication there is definite reference only to specimens of oculata from Formosa, but Baranov added that the species was known to him from Java and South India (' Auch von Java mir bekannt aus Baoris bada Moore geziichtet und aus Siidindien aus Plusia sp. gezogen '). We have not located any specimens from these additional localities that could have been seen by Baranov, but we consider that they would in any case be without type status (as there is no evidence that they were available to Baranov at the time of description).

Meigenia tnutabilis nobilis Baranov, 19266 : 168. LECTOTYPE <$, JUGOSLAVIA : Serbia, Golubac, 3o.iv[publ. as vi].ig25 (USNM). Genitalia on slide.

The original publication shows no evidence of how many specimens Baranov saw at the time of description, but the single male of nobilis in Baranov's collection conforming to the original data bears a red Baranov label reading ' Typi ' ; we deduce from this that he had more than one original specimen, and accordingly designate the available specimen as lectotype.

Meigenia tnutabilis pilosa Baranov, 19266 : 168. Holotype <$, JUGOSLAVIA : Serbia, Golubac, 24. vi. 1925 (USNM). Genitalia on slide.

There is no evidence that the original type-material of subspecies pilosa consisted of more than one specimen, and the male in the USNM collection having the data as published by Baranov is considered to be the holotype.

Baranov did not state the number or sex of his original specimens, but gave the date as i6.viii.i923- We consider all the above-listed specimens to be original syntypes, but it should be noted that none of them bears the day and month date ' i6.viii ' cited in the original publication.

Beeson & Chatterjee (1935 : 177) published this name before Baranov's description, but gave only four lines on the life history and no description ; the name is nomenclaturally unavailable from Beeson & Chatterjee (1935) under Article i3a (i) of the International Code of Zoological Nomenclature, 1961.

Townsend (1941 : 291), for M. bezziana, cited ' Ht ' (= holotype) male and ' At ' ( = allotype) female in London without further information ; since there are at least two male original syn types Townsend 's statement does not restrict the name to a single specimen and is not a valid lectotype fixation. A lectotype is therefore here newly designated.

Phorocera magna Baranov, 19340 : 46. LECTOTYPE $, INDONESIA : Moluccas, Batjan, viii.1929 (W. Roepke) (USNM : genitalia slide only).

This species was described from material obtained by W. Roepke in July and August, 1929, while investigating the parasites of Thosea moluccana Roepke, 1935 (Lepidoptera : Limacodidae), a serious pest of coconut in Batjan island, Moluccas. The description of Phorocera magna by Baranov (19356) was published as an unpaginated appendix following the last page (p. 38) of Roepke's (1935) account of his work in Batjan, and was based upon four syntypes (2 <$, 2 $) with the data cited by Baranov as ' Molukkeninsel Batjan, vii, 1929 (W. Roepke) '; this description, which Baranov intended to be the original description, had however already appeared in print in an earlier paper (Baranov, 19340) while Roepke's work was still in press. The name Phorocera magna is therefore nomenclaturally available from the 1934 paper here cited.

Baranov (19340), as we^ as repeating the description, mentioned two small specimens of P. magna from Ceylon, but we do not accept these specimens (which, in any case, we have been unable to locate) as original syntypes because the description was made only from the Moluccan material.

Unfortunately we have been unable to locate any of the four original syntypes, but a slide preparation of the male genitalia of one of them is in USNM (ex Baranov collection) and this we have fixed as lectotype. However, there are four specimens of P. magna in the Museum Zoologicum Bogoriense and four specimens in the Central Agricultural Research Institute, Bogor, which were all collected by Roepke in Batjan and reared from Thosea moluccana ; none of these other eight topotypic specimens existing in Bogor have been labelled by Baranov and all have the date ' xii.i92g ' (the original material was collected in July or August), and there is no evidence that any of them are syntypes. Furthermore, each of them has a locality label reading ' Penamboean, Batjan ', and it is unlikely that Baranov would have omitted the first of these words in his unusually full citation of data for P. magna if some of these specimens were his original material. Thus we are convinced that none of the specimens now in Bogor represent type-material. It is especially surprising that Baranov's own collection at the U.S. National Museum does not contain at least one complete syntype, as Baranov normally retained part of his type-series if this consisted of several specimens. Finally, we should record that Baranov (19340) cited the month date of the original syntypes as ' VIII ', but in the later description published (Baranov, 19356) he gave it as ' VII '. In the absence of syntypes we are unable to say for certain which is correct, but the lectotype genitalia slide has the August month date and we accept this as correct. The month date ' xii ' on specimens in Bogor might also possibly be in error for ' vii ' or ' viii ', but we have no evidence on this.

The specimens of P. magna in the Museum Zoologicum Bogoriense are three females and one male, but we do not know how many of each sex are present among the four specimens in the Central Agricultural Research Institute, Bogor.

Sauter) (J ? USNM, ? DEI).

The paralectotype series is mixed and consists of two species of Phorocerosoma Townsend (see Crosskey, 1966 : 108-109). The two females in the DEI collection with the data ' Toa Tsui Kutsu ' and ' Kankau ix.i9i2 ' are actually specimens of Phorocerosoma vicarium (Walker) and are not conspecific with the lectotype of anomala and most of the paralecto- types (which have four strong marginal setae on the third abdominal tergite and are actually specimens of Phorocerosoma postulans (Walker), the senior synonym of anomala). The lectotype and all paralectotypes of anomala bear the name ' Exorista anomala ' in Baranov's writing.

Baranov (1936 : 99) makes it clear that the description of anomala is based solely on Formosan specimens, although he cited the data (' i $, Ugi Is., 6.V.I934, leg. R. A. Lever ') of a specimen from the Solomon Islands. This specimen is in the BMNH collection and was cited by Crosskey (1966 : 108) as a syntype of anomala : we now consider, however, that it has no type-status.

At present the name anomala is in synonymy with postulans, but it should be noted that if again treated as valid in combination with Phorocerosoma the correct spelling will be anomalum (under Article 34(b) of the International Code of Zoological Nomenclature, 1961).

In the original publication Baranov mentioned fourteen specimens (n <J, 3 $) ; we have located this total, but 12 <J and 2 $. One of the males in USNM collection has a pair of proclinate orbital setae and may have been mistaken for a female, thus accounting for the discrepancy. The female paralectotype from Kankau in DEI collection, and one of the males from Kanshizei in the same collection, have lost the abdomen. The male paralecto- type from Sokutsu is mis-associated with the lectotype, and is a specimen of Zygobothria atropivora (Robineau-Desvoidy) ; the male paralectotype in DEI with date 7.viii.i9i2 from Kankau is also mis-associated and is a specimen of a Sisyropa species.

Baranov based the original description on two males and a female, all from Tainan. The female syntype has not been located. The Baranov collection in USNM contains four males that have the same data as the lectotype and are all labelled by Baranov as ' n.sp. N. Baranoff ' in his usual style of label. Not all of these can be regarded as syntypes, since the original description mentions only two males (i.e. one in addition to the lectotype) ; one of them, however, has had the hypopygium extracted and it is considered that this one is the second specimen of the original pair (it is therefore listed as male paralectotype above, and has been labelled as such).

Sturmia unguicularis Baranov, 19340 : 480. Holotype <J, JAVA : Ngantang (Frau Neuhaus) (USNM).

The holotype lacks the genitalia and the slide preparation has not been located. In the original description Baranov mentioned a second specimen from New Caledonia which he expressly excluded from the type-material by the following statement : ' Vorliegende Beschreibung bezieht sich auf das javanische Exemplar und das neukaledonische Exemplar, welches in ziemlich schlechten Zustande ist, betrachte ich nur als Idiotype und nicht als Cotype '. This specimen, in poor condition as Baranov said, is in the BMNH collection and has the following data : <£, NEW CALEDONIA : Noumea, 17^.1928 (T. D. A. Cockerell).

Not all of the dates of the paratype material were recorded by Baranov in the original publication, but we are nevertheless satisfied that all the specimens (other than the holotype) listed above are acceptable as paratypes.

Baranov did not state the number of male specimens on which the description was based, but Townsend (1939 : 145) assumed that the specimen in DEI collection was the ' Ht ' ( = holotype). We do not accept this as a valid lectotype fixation because there are other male syntypes with Baranov's ' n.g., n.sp. ' labels in other collections, and we therefore here fix the lectotype of T. sauteri by present designation.

Tricholyga psychidarum Baranov, 19340 : 47. Holotype $, SUMATRA : Pematang Siantar, Naga Hoeta Estate, 1750 ft., io.x.i93i, ex larva of bagworm (R. I . Nel) (BMNH). Genitalia on slide.

In the original description Baranov characterized psychidarum as having hairy eyes, but mentioned that most specimens of the type-material had the hairing rubbed off (' bei den meisten Exemplaren Behaarung abgerieben '). From our own examination of the holotype and paratype material we are sure that two separate species are involved, one having the eyes virtually bare in the natural state and the other having the eyes conspicuously long haired, for the eye difference is associated with quite different forms of male genitalia ; other material of the complex now available also confirms this conclusion. The holotype has bare eyes, and the name psych-idarum therefore applies to the species with this character. Most of the above-listed paratypes have bare eyes and are conspecific with the holotype, but two of the female paratypes are hairy-eyed and mis-associated : these are the USNM specimen with date 2.1.1932 and the BMNH specimen from Mardjandi Estate, 24.1.1932. No applicable name is known to us for the hairy-eyed species, which appears at present to be undescribed. The BMNH collection contains a hairy-eyed male with data ' Sumatra, Naga Hoeta Est., P. Siantar, 8.xii.3o R. I. Nel ' but it bears a determination label in Baranov's writing as ' Eutachina psychidarum Baranoff ' and is evidently not an original paratype. The same collection also has a hairy-eyed female with data ' Malaya, Chebiot Estate, Labu, 28.9.1928 ', but is also labelled by Baranov as ' Eutachina psychidarum Bar. ' and is presumed not to be the paratype mentioned in the original publication from ' Malaya, 28. ix. 1928 ', which has not been seen.

Vibrissina hokkaidensis Baranov, 19350 : 554. LECTOTYPE $, JAPAN : Hokkaido, Sapporo, 19 [publ. as 12]. x. 1923 (S. Takano) (USNM). Genitalia in situ. Paralectotype : i 9, same data as lectotype (USNM).

Voria edentata Baranov, 19320 : 83. Holotype <$, FORMOSA : Koshun, Kankau, 22. vi. 1912 (H. Sauter) (not located and possibly lost : formerly in DEI).

Baranov described this species only from the single specimen recorded above and cited the DEI collection as the type depository. The holotype was later seen and recorded by Hennig (1941 : 192), who also cited the locality and date as ' Kankau, VI ' for the type and men- tioned three other specimens in the DEI collection (another specimen from Kankau and two

54 C. W. SABROSKY & R. W. CROSSKEY

just with the data ' Formosa '). We have been unable during the preparation of the present work to locate the holotype specimen and consider that it is possibly lost ; furthermore, the DEI collection now contains only two of the three other specimens recorded by Hennig (viz. a male with data ' Kankau y.vii.igia H. Sauter ' and female with data ' Formosa I Sauter ', both determined by Baranov as Voria edentatd).

In a revision of Old World Voriini the data of the ' type ' of edentata has been cited by d'Aguilar (1957 : 2^2) as ' 1 '^e de Taiwan : Kankau, recolte en juillet-aout 1912, par H. Sauter ', but Baranov clearly cited the holotype date as ' 22. vi. 1912 ' in the original publica- tion and Hennig also found the month date to be June. Thus probably d'Aguilar did not see the true holotype from DEI, but may have seen the later determined specimen from Kankau in DEI collection (recorded above), although this specimen bears no month date August. Dr. d'Aguilar (personal communication) has kindly confirmed that the specimen seen by him was returned to DEI, and Dr. L. P. Mesnil has confirmed that the holotype is not on loan to him at Delemont.

It should be noted that the slide preparation of the male genitalia from the specimen of V. edentata with the date ' Kankau y.vii.1912 ' is also in the DEI collection, but not the slide preparation from the holotype.

In the original publication Baranov recorded a specimen from New Britain that is now in the BMNH collection and has the following data : $ (without abdomen) NEW BRITAIN : Rabaul, 29.1.1934, ex lepidopterous larva (/. L. Froggatt). This specimen, however, has only a Baranov determination label as ' Zenillia roseanella Baranoff ', and it is not a syntype because Baranov expressly stated that the description was based on ' Exemplare ' from Formosa which he was publishing in the 1936 paper (' hier an dieser Stelle ') as it had not yet appeared elsewhere. Thus the name is based on syntypes from Formosa, of which only one (here fixed as lectotype) has been located.

PART II.— BARANOV'S MANUSCRIPT NAMES THAT HAVE BEEN PUBLISHED.

We bring together in the following alphabetical list all those manuscript names of Baranov that have appeared in print, either as nomina nuda or as species-group names made available by the action of later authors. The available species-group names are shown in bold type.

Actia mallochiana Gardner, 1940 : 178 (Actia mallochiana Baranov MS). Available name, attributable to Gardner.

TYPE-MATERIAL OF TACHINIDAE 55

Gardner described the puparium of a species of Tachinid fly under Baranov's hitherto unpublished manuscript name Actia mallochiana. Under Article 10 of the International Code of Zoological Nomenclature, 1961, the name mallochiana is made available by, and must be attributed to, Gardner.

Allophora dubiosa Baranov in Hennig, 1941 : 187. Nomen nudum.

Hennig listed without description (as ' Phasia dubiosa Baranoff ') a specimen in DEI collection from Formosa that bears a Baranov label as ' Allophora dubiosa n.sp. N. Baranoff ' ; the name was not published by Baranov and remains a nomen nudum.

Argyrophylax rufitibialis Baranov in Hennig, 1941 : 196. Nomen nudum.

Hennig listed, under this name and without description, a specimen from Hoozan in Formosa in DEI collection ; the name was not published by Baranov and remains a nomen nudum. Mesnil (1944 : 27) also cited the name, but did not validate it by description.

Bactromyia compsiluroides Baranov in Baranov, 19386 : 409. Nomen nudum.

Baranov mentions compsiluroides as a Formosan species in his original description of Bactromyia crassiseta Baranov, 1938, but without characterizing it, and the name remains a nomen nudum.

Cossidophaga kalshoveni Baranov in Baranov, 1934/1 161. Manuscript name cited in synonymy, unavailable.

This name was cited by Baranov in synonymy under Cossidophaga atkinsoni (Aubertin), a species described by Aubertin (1932) as Podomyia atkinsoni. Baranov (19347 : I^i), when describing the new genus Cossidophaga for atkinsoni, abandoned his intended specific name kalshoveni for this species but published the latter name in synonymy ; it is unavailable under Article n (d) of the International Code of Zoological Nomenclature, 1961.

Crocuta taiwanica Baranov in Hennig, 1941 : 195. Nomen nudum.

Hennig listed without description (as ' Siphona taiwanica Baranoff ') four specimens in the DEI collection from Macuyama and Toa Tsui Kutsu in Formosa ; the name was not published by Baranov and remains a nomen nudum.

Ctenophorocera sturmioides Mesnil, 1950 : 126 (Prosopaea sturmioides Baranov MS). Available name, attributable to Mesnil.

Mesnil (1950 : 126) described Ctenophorocera sturmioides as a new species based upon a male holotype specimen (in DEI collection) labelled by Baranov as ' Prosopaea sturmioides n.sp. N. Baranoff' and with the data : — Formosa : Sokutsu, vi.igia (H. Sauter). Mesnil placed the species in his subgenus Parapales Mesnil, and the holotype is labelled (in addition to Baranov's label) as ' Parapales sturmioides Mesn. ' in Mesnil's writing.

Hennig (1941 : 196) listed the name Prosopaea sturmioides Baranoff but gave no descrip- tion ; he mentioned three specimens in DEI collection from Formosa, one without further data, one from Toa Tsui Kutsu, and one from Sokutsu, of which only the last was seen by Mesnil (i.e. the holotype cited above). It should be noted that the month date of the holo- type specimen from Sokutsu is ' vi ' as given by Hennig, and not ' v ' as given by Mesnil (1950 : 127).

Cuphocera varia form formosana Baranov in Baranov, 1936 : 98. Manuscript name cited in synonymy, unavailable.

This name was cited by Baranov in synonymy under the true Cuphocera varia (Fabricius), and is unavailable under Article 1 1 (d) of the International Code of Zoological Nomenclature, 1961.

Cuphocera varia form malayana Baranov in Baranov, 1936 : 98. Manuscript name cited in synonymy, unavailable.

56 C. W. SABROSKY & R. W. CROSSKEY

Dolicholon ater Gardner, 1940 : 177 (Dolichocolon ater Baranov MS). Available name, attributable to Gardner.

Gardner described and figured the puparium of a species of Tachinid fly under Baranov's hitherto unpublished manuscript name Dolichocolon ater. Under Article 10 of the Inter- national Code of Zoological Nomenclature, 1961, the name ater is made available by, and must be attributed to, Gardner.

Euhapalivora indica Gardner, 1940 : 179 (Euhapalivora indica Baranov MS). Available specific name, attributable to Gardner.

Gardner described and figured the puparium of a species of Tachinid fly under Baranov's hitherto unpublished manuscript name Euhapalivora indica. The specific name indica, even though published in combination with an unavailable genus-group name, is available under Article n (g) (ii) of the International Code of Zoological Nomenclature, 1961, and is attributable to Gardner under Article 10. The generic name Euhapalivora (as mentioned by Crosskey, 19670: 13) is not accompanied, however, by a definition of the generic taxon and is a nomen nudum which is unavailable under Article 13 (a).

The species indica has been assigned to the genus Pseudoperichaeta Brauer & Bergenstamm by Crosskey (19676).

Exorista apicalis Baranov in Hennig, 1941 : 193. Nomen nudum.

Hennig listed without description 20 specimens in DEI collection from Kankau and Sokutsu in Formosa ; the name was not published by Baranov and remains a nomen nudum. Mesnil (1950 : 153) cited Exorista apicalis Baranov as a synonym of Sisyropa soror Mesnil, 1944, but it is nevertheless unavailable from Mesnil under Article n (d) of the International Code of Zoological Nomenclature, 1961.

Exorista grisellina Gardner, 1940 : 177 (Exorista grisellina Baranov MS). Available name, attributable to Gardner.

Gardner described and figured the puparium of a species of Tachinid fly under Baranov's hitherto unpublished manuscript name Exorista grisellina. Under Article 10 of the Inter- national Code of Zoological Nomenclature, 1961, the name grisellina is made available by, and must be attributed to, Gardner.

Exorista maculiventris Baranov in Hennig, 1941 : 194. Nomen nudum.

Hennig listed, under this name and without description, two specimens in DEI collection from Kankau in Formosa ; the name was not published by Baranov and remains a nomen nudum. Mesnil (1950 : 154) cited Exorista maculiventris Baranov as a synonym of Sisyropa thermophila (Wiedemann, 1830), but it is nevertheless unavailable from Mesnil under Article ii (d) of the International Code of Zoological Nomenclature, 1961.

Exorista pulchra Baranov. See Zenilliana pulchra Mesnil.

Exorista simulator Baranov in Hennig, 1941 : 194. Nomen nudum.

Hennig listed, under this name and without description, three specimens in DEI collection from Formosa, two without further data and the other one from Toa Tsui Kutsu ; the name was not published by Baranov and remains a nomen nudum. Mesnil (1949 : 66) cited the name ' simulator Bar. (in litt.) ' as a synonym of Phorocerosoma forte Townsend without noting the generic name used by Baranov ; it is nevertheless unavailable under Article ii (d) of the International Code of Zoological Nomenclature, 1961.

Exorista winthemioides Baranov. See Nemosturmia winthemioides Mesnil.

Gymnodexia orientalis Baranov in Baranov, 19340 : 49. Nomen nudum.

Baranov (19340 : 49), in the original description of Gymnodexia atkinsoni, made the statement : ' Am nachsten zu orientalis mihi (in litteris) ', but nowhere published a descrip- tion of orientalis. Hennig (1941 : 191), under the name Gymnodexia orientalis Baranoff but without description, listed three specimens in the DEI collection from Formosa. The name remains a nomen nudum.

Hyalomyodes orientalis Baranov in Hennig, 1941 : 189. Nomen nudum.

Hennig listed, under this name and without description, a specimen in DEI collection from Tainan in Formosa ; the name was not published by Baranov and remains a nomen nudum.

Kosempomyia sauteri Baranov in Baranov, I934/ : 165. Manuscript name cited in synonymy, unavailable.

This name was cited by Baranov in synonymy with Kosempomyiella rufiventris Baranov, and is unavailable under Article 1 1 (d) of the International Code of Zoological Nomenclature, 1961. Hennig (1941 : 187) listed the name without description, and mentioned three speci- mens in DEI collection, two from Formosa without other data and one from Kosempo in Formosa.

Leskia deaurata Baranov in Hennig, 1941 : 190. Nomen nudum.

Hennig listed, under this name and without description, a specimen in DEI collection from Sokutsu in Formosa ; the name was not published by Baranov and remains a nomen nudum.

Masicerella indistincta Gardner, 1940 : 178 (Masicerella indistincta Baranov MS). Available specific name, attributable to Gardner.

Gardner described and figured the puparium of a species of Tachinid fly under Baranov's hitherto unpublished manuscript name Masicerella indistincta. The specific name indistincta, even though published in combination with an unavailable genus-group name, is available under Article n (g) (ii) of the International Code of Zoological Nomenclature, 1961, and is attributable to Gardner under Article 10. The generic name Masicerella (as mentioned by Crosskey, 19670 : 18) is not accompanied, however, by a definition of the generic taxon and is a nomen nudum which is unavailable under Article 13 (a).

Medinodexia formosana Baranov in Hennig, 1941 : 190. Nomen nudum.

Hennig listed, under this name and without description, a specimen in DEI collection from Tainan in Formosa ; the name was not published by Baranov and remains a nomen nudum.

Meigenia setosa Baranov in Hennig, 1941 : 193. Nomen nudum.

Hennig listed, under this name and without description, a specimen in DEI collection from Hoozan in Formosa ; the name was not published by Baranov and remains a nomen nudum.

Nemosturmia winthemioid.es Mesnil, 1949 : 76 (Exorista winthemioides Baranov MS). Available name, attributable to Mesnil.

Mesnil (1949 : 76) described Nemosturmia winthemioides as a new species based upon a male holotype specimen from Formosa in the DEI collection labelled by Baranov as ' Exorista Winthemioides ' ; Mesnil erroneously attributed authorship of the name win- themioides to Baranov, but Baranov did not publish the name, and authorship of the name winthemioides is attributable to Mesnil.

Hennig (1941 : 194) listed the name ' Exorista winthemioides Baranoff ' and mentioned the single specimen in DEI collection (now the holotype of Nemosturmia winthemioides Mesnil), but he gave no description.

Paradionaea orientalis Baranov in Hennig, 1941 : 189. Nomen nudum.

Hennig listed, under this name and without description, a specimen in DEI collection from Kankau in Formosa ; the name was not published by Baranov and remains a nomen nudum.

Phasia dubiosa Baranov. See Allophora dubiosa Baranov.

Phorinia flavipalpis Baranov in Hennig, 1941 : 194. Nomen nudum.

Hennig listed, under this name and without description, five specimens in DEI collection from Kankau in Formosa ; the name was not published by Baranov and remains a nomen nudum.

Phoriniophylax fetnorata Mesnil, 1957 : J4 (Phoriniophylax femorata Baranov MS). Avail- able name, attributable to Mesnil.

58 C. W. SABROSKY & R. W. CROSSKEY

Hennig (1941 : 196) listed, under this name but without description, two specimens in DEI collection from Tainan in Formosa that are determined by Baranov as ' Phoriniophylax femorata ', but Baranov never published this name. Later Mesnil (1944 : 27) placed the name femorata Baranov in combination with Argyrophylax Brauer & Bergenstamm, but without validating it by description so that it remained at that time (1944) a nomen nudum. In a more recent work, however, Mesnil (1957 : 14) appended to the description of his new subspecies Argyrophylax nova novella Mesnil the following remark : ' il est probable que Phoriniophylax femorata Baranov est congenerique de cette espece [Argyrophylax nova Mesnil]. Elle s'en distingue par ses pattes jaunes a tarses noirs '. We consider that this statement purports to give characters differentiating the taxon femorata, and that the name is nomenclaturally available under Article 13 (a) (i) of the International Code of Zoological Nomenclature, 1961 ; under Article 10 it takes the authorship and date of Mesnil, 1957.

Prosopaea sturmioides Baranov. See Ctenophorocera sturmioides Mesnil.

Siphona taiwanica Baranov. See Crocuta taiwanica Baranov.

Sumpigaster formosensis Baranov in Hennig, 1941 : 190. Nomen nudum.

Hennig listed, under this name but without description, three specimens in DEI collection from Formosa (no other data) ; the name was not published by Baranov and remains a nomen nudum.

Zenilliana pulchra Mesnil, 1949 : 68 (Exorista pulchra Baranov MS.) Available name, attributable to Mesnil.

Mesnil (1949 : 68) described Zenilliana pulchra as a new species based upon a male holotype specimen from Sokutsu, Formosa, in the DEI collection, but erroneously attributed author- ship of the name to Baranov ; however, Baranov did not publish it, and authorship of the name pulchra is attributable to Mesnil.

Hennig (1941 : 194) listed the name ' Exorista pulchra Baranoff ' and mentioned the single specimen in DEI collection (now the holotype of Zenilliana pulchra Mesnil), but he gave no description ; hence Exorista pulchra Baranov in Hennig is a nomen nudum.

BOMBYLIIDAE, AND A FIRST RECORD OF NEMESTRINIDAE FROM SOKOTRA (DIPTERA)

D. J. GREATHEAD

SYNOPSIS

The Bombyliidae of Sokotra are reviewed and new species described as the result of the examination of a new collection of specimens from the island made by K. M. Guichard in 1967. The first record of a Nemestrinid, Atriadops cinnamonea Brunetti, is also reported.

THE first collections of Diptera from Sokotra were made by W. R. O. Grant, pub- lished by Ricardo (1903), and by O. Simony, published by Becker (1910), both in the same year, 1899. No subsequent collections of Diptera were made until 1967 when a collecting expedition to Southern Arabia and Sokotra was made by K. M. Guichard. New material of all the described species from the island has thus become available as well as material of other species both new and not previously known from the island. This new material was collected between March and May, whereas previous visitors who collected Bombyliidae were there in December to February. This difference in timing has not, as far as can be inferred from the Bombyliidae, made a marked difference in the species in flight.

All three collectors travelled in the relatively flat northern part of the island. No specimens of Bombyliidae are available from the higher parts of the Haggier moun- tains or the southern coastal area. Popov (1957) has provided a description of the vegetation, which can be classified as subdesert and, like the fauna, includes a high proportion of endemics.

The Bombyliidae now known from the island comprise 16 or 17 species, of which 9 are not known from outside Sokotra and Abd-el-Kuri. The remainder are all recorded from the arid adjoining areas of the African mainland and four from Southern Arabia. Of the endemic species only one, Bombylius socotrae, is not clearly allied to species known from neighbouring parts of Africa and Arabia. As, however, very little is known of the Bombyliidae of the Somali Peninsula any detailed comparison is premature. Examination of the material leaves a general impression of a tendency to greater size and more striking colouring than mainland counterparts, thus Petrorossia sokotrae is on average much larger than any African species and the specimens of Hemipenthes inauratus and Anthrax fuscipennis are all at the upper limit of size found on the mainland. Villa dioscoridae and Exoprosopa punctipennis both show the latter tendency to a striking extent.

The record of a Nemestrinid from the island is of interest both because it adds a new family to the faunal list and because it is apparently the same as a species described from Malawi. However, the extent of the distributions of Nemestrinidae cannot be assessed as they are seldom captured.

Family BOMBYLIIDAE Bombylius mollis Bezzi

Bombylius mollis Bezzi, 1921 : 15.

The specimen listed as Bombylius sp. by Ricardo (1903) has been examined ; although the proboscis is missing and the dorsal surface largely denuded, there is no doubt as to its identity. B. mollis is a widespread species ranging from Ethiopia to Transvaal.

SOKOTRA : Adho Dimellus, 3500 ft, i <£, 9.11.1899 (W. R. 0. Grant), BM(NH).

Bombylius socotrae sp. n.

A single female Bombylius, the only other specimen of the genus from Sokotra, represents a remarkable new species with a combination of characters not fitting into any of the groupings erected by Bezzi (1924). It is nearest to the B. minor group in its pale whitish pubescence, pale legs with black spines, hyaline wings and black body. These characters, as well as the brown antennae, black proboscis and complete absence of black hairs or bristles except on the legs distinguish it from other species.

Head : black with heavy grey tomentum except for the buccal margin which is yellowish grey. Eyes separated by almost three times the width of the ocellar tubercle at the vertex, which is tumid and separated by a groove from the frons. All hair and scales white, shaggy on frons and face, shorter elsewhere and with a broad band of scales surrounding the eyes. Antennae with third segments missing, first and second reddish brown to greyish, first three times the length of second, hairs on first white, second bare except for minute yellowish spicules. Proboscis black, with a reddish base twice the length of the head, palpi reddish brown with colourless spicules. Thorax : black, heavily dusted with grey-brown tomentum on the dorsal surface and grey elsewhere, densely covered in greyish white hair, macrochaetae glistening white. Legs : coxae black, remainder brown, lighter on the femora and tibiae, darker on the tarsi which are blackish at their tips. Hair on femora and scales white, spines and spicules well developed, black. Fore and mid femora unarmed, hind with a row of six anteroventral spines as well as apical spines above and a single anterodorsal and a single posterodorsal one near the apex. Claws mostly missing, posterior ones black with a reddish base, pulvilli white, almost as long as the claws. Wings : hyaline but tinged opaque yellowish at the base in costal cell and in first basal cell. Veins reddish brown at fore border, paler towards the posterior margin where they are yellowish brown. Venation ; middle crossvein almost at middle of discoidal cell, first posterior cell blunt at apex and stalk long, longer than penultimate section of vein. Squamae and alulae white with white fringes. Hal teres brownish tinged. Abdomen: black with a brownish grey tomentum, tergites reddish at their sides and yellowish on the posterior margins, more broadly at the apex than base. Hairs and bristles white, the latter inconspicuous, weak, hairlike. Ovipositor concealed in a dense tuft of yellow hair.

Length of body 9 mm ; of wing 8 mm ; of proboscis 4 mm.

BOMBYLIIDAE, AND NEMESTRINIDAE FROM SOKOTRA 69

Systoechus somali Oldroyd Systoechus somali Oldroyd, 1947 : 105.

This species, which is well known as a predator of the desert locust, Schistocerca gregaria Forskal, is common in Somalia, the Ogaden in Ethiopia and northern Kenya (Hynes, 1947 ; Greathead, 1958). Only a single specimen was collected in Sokotra, but it shows no differences from mainland specimens.

The species belongs to the group with hyaline wings, entirely pale bristles on the legs and no abdominal bristles in the male. The male is distinguished from other species by the entirely blackish hair on the frons and face, dark brown pleural hair, and pale, almost white, silky abdominal hair. The female has white facial hair, three grey vittae on the thorax and the abdomen with pale hairs and dense rows of dark bristles across the tergites.

SOKOTRA : Hammadero, noo ft, i $, 18.^.1967 (K. M. Guichard], BM(NH).

Geron sp. $

Hesse (1938) has shown that the species of Geron are remarkably similar in external characters and can only be distinguished with difficulty except by the characters of the male genitalia. He has also shown that, at least in southern Africa, there are many more species than was formerly believed. It is thus impossible in the present state of our knowledge to identify females from other regions reliably. The present specimens however run to G. nigrifacies in Hesse's (1938) key and approximate to his description. From G. nigrifacies they differ in that the fore tibiae are paler, the brassy scaling extends over the scutum and the hyaline wings have paler yellowish to yellowish brown veins.

SOKOTRA : Hammadero, noo ft, 2 ?, 8.^.1967 (K. M. Guichard), BM(NH) and author's collection.

These specimens may be conspecific with the pair identified by Becker (1910) as G. gibbosus Meigen, which it has not been possible to trace.

Phthiria sp.

Ricardo (1903) reported two male Phthiria sp. from Sokotra. No specimens of this genus are present in Guichard's material and unfortunately the specimens collected by Grant can no longer be found in the British Museum.

Chiasmella sica sp. n.

The genus Chiasmella was erected by Bezzi (1924) for the single species brevipennis Bezzi from Southern Yemen. Doubt has been expressed whether the genus was distinct from Chionamoeba Sack, but Greathead (19670:) showed that it is a distinct genus of uncertain affinities, possibly closest to the Tomomyzinae in which he pro- visionally included it. The present species agrees in most characters with C. brevipennis, differing most notably in that the wing has an infuscated fore border, and that the tomentum and hair on the frons is gold in the male. It is a darker, more powerfully built species resembling a There vid in appearance.

70 D. J. GREATHEAD

<J. Head : black, but frons red-brown and buccal rim yellowish. Occiput above and vertex covered in brown tomentum and blackish brown hair, frons with dense glittering gold tomentum and fine gold hairs, face with greyish tomentum and white hair and lower part of occiput with white hair, which is flattened and adpressed at the margins of the eyes. Antennae with first segment brown, second and third blackish, hairs pale yellowish. Styliform part of third longer than in C. brevifacies, equal in length to that of the rest of the antenna. Proboscis and palpi black, labella brown, hairs colourless.

Anthrax sokotrae Ricardo, 1903 : 367. Thyridanthrax sokotrae (Ricardo) Bezzi, 1924 : 22.

This species, which clearly belongs to the genus Petrorossia, was unaccountably listed by Bezzi (1929) under Thyridanthrax. It is one of the largest species of the genus but very variable in size ; the present specimens range between 5 and 12 mm. It belongs to the P. fulvipes Loew section of the genus but lacks a distinct wing pattern, the wings being tinged brownish, darker at the base and along the fore border and identical in both sexes.

Head : black, with grey tomentum except on the vertex and upper part of the frons, which are velvety black. Ocellar tubercle prominent, vertex almost three times its width in the male and only slightly wider in the female, and with a deep sulcus behind the ocellar tubercle separating the inflated halves of the occiput. Hairs on vertex, frons except for a few at the base of the antennae, and on the upper part of the sides of the occiput to the level of the antennae, black,

Anthrax fuscipennis (Ricardo)

Argyramoeba fuscipennis Ricardo, 1903 : 366. Anthrax fuscipennis (Ricardo) Becker, 1910 : 132.

Becker (1910) placed his A. dentata as a synonym of A. fuscipennis ; as thus accepted the species is widespread in the Mediterranean region, Arabia and north eastern Africa. Although many species of Anthrax are widespread and subject to variation in details of the colour pattern, this interpretation of the species should be treated with caution until the hypopygia of males from a number of localities can be checked with those of males from Sokotra. Unfortunately this is not yet possible as no male specimens have been captured on the island. The form of the hypopygium of material from northern Ethopia has been illustrated (Greathead, 19670).

Three female specimens of a species of Spogostylum, in rather poor condition, appear to belong to 5. ventrale Bezzi ; however as the species of this genus are notoriously difficult to identify on external characters and many are apparently restricted to small areas and replaced by closely similar species in adjoining areas, the identification is regarded as provisional.

H . inauratus is now known from localities in Ghana (Bowden, 1964) east to Somalia (Bezzi, 1924) and from Arabia (Klug, 1832) but has not previously been reported from Sokotra. It is one of the most beautiful Bombyliidae and is at once recognized by the purplish black head and thorax, dimidiate black wing pattern and golden scaling of the dorsal surface of the abdomen. The Sokotra specimens fall within the variation indicated in the quoted descriptions and are thus not morphologically distinct from continental specimens.

Villa dioscoridae sp. n.

(Text-figs. 3-5)

Anthrax hottentotta Linnaeus, 1758 : 590 ; Ricardo, 1903 : 368 [Mis-identification]. Hemipenthes circumdatus Meigen, 1820 : 143 ; Becker, 1910 : 133 [Mis-identification].

Recent work, taking a more critical view of Villa spp. and making use of the characters of the hypopygium, has suggested that there are more species in the hottentotta - circumdata group than was formerly recognized (Lyneborg, 1965). Ricardo (1903) even regarded circumdata as a synonym of hottentotta. For the present purpose it is sufficient to state that the Sokotran species is distinct and not a form of one of the Palaearctic members of the complex. Neither is it conspecific with the allied African species galla Greathead (1967 a) to which it is closest.

From all the other species of the complex it differs in the brighter, more golden and less yellow pubescence, and the more clear cut, contrasting black and yellow banding of the abdomen, in having black hair on the face, black scales only on the legs, and black bands of scales across the sternites.

Holotype <£. Head : black, as V. hottentotta (sensu Engel, 1932-7) or V. galla, except that all the hairs and scales on the frons and face are black, only those on the occiput being yellow and that the third antennal segment is tinged reddish. Thorax : similar to the other species but the hairs shorter than that of V. hottentotta and more richly coloured than either species ; that of the collar, dorsal surface and prealar callus deep golden yellow with a reddish tinge, that on remaining parts of the pleura straw-coloured. Legs : dark reddish, clothed in black scales and hairs except coxae ; fore and mid coxae with yellow hairs on basal half and black hairs and bristles on apical half, hind coxae mainly with yellow pubescence and only a few blackish bristles at the apex. Wings : veins darker, blackish, basal comb covered in black scales except for a patch of silvery ones at the base in addition to the silvery ones of the ' epaulette '. Venation normal. Squama opaque white with a pale yellow fringe. Halteres pale yellow-brown with a cream knob. Abdomen : hair short as V. galla but scales more distinctly yellow and denser, so that the pattern of light and dark bands is sharper. First tergite with shiny black scales, second with pale straw-yellow scales on basal third, remainder black, third with a narrow band of pale scales at the base, remainder black, fourth basal two-thirds pale, apical third black, fifth and sixth black with fringes of pale scales and tufts of long black

Thyridanthrax argentifrons (Becker) comb. n.

Hemipenthes argentifrons Becker, 1910 : 133.

Becker (loc. cit.) described the species from two males. The present material consists of three rather denuded females, which agree more or less with Becker's description except that there are few silver scales on the posterior abdominal tergites. As such characters are liable to sexual dimorphism (e.g. T. cunamae Greathead, 19670) there is little doubt that the present specimens represent the female of T. argentifrons. It is one of the group of Paragus-\ike species, as noted by Becker, but is at once distinguished from other known species by the heavy silver scaling on the frons combined with the absence of yellow hair or scaling from the abdomen with its contrasting black and white pattern. The following des- cription is based on the females and includes differences from the males as described by Becker.

Head : black, facial cone bluntly rounded at its apex, face convex, frons two and a half times the width of the ocellar tubercle at the vertex (in male twice the width) . Hair on frons and face short, sparse, glistening black. Scales on lower half of frons large, dense, silver, projecting over bases of antennae, on upper part of frons and occiput small, silvery, opalescent, on face similarly opalescent but appearing glistening black when viewed from some angles. Antennae black, first and second segments cylindrical with short black hair except on the underside of first where it is longer, third one and a half times length of first and second, broad at base and closely applied to the second, tapering rapidly to a thick styliform part about two-thirds the length of the segment and terminating in a minute spicule. Proboscis black at base, brown towards apex, tips of labella projecting beyond buccal cavity. Palpi dark brown with brown hairs. Thorax : black with a brown tomentum. Hair of collar and noto- pleural tuft pale brownish yellow, not red-brown as described by Becker for the male. Dorsal surface denuded but according to Becker the males have red-brown hair and metallic golden scales. Notopleural stripes well developed, white, metapleural tuft and plumula also white. Remaining areas of pleura bare or possibly denuded. Prosternum with a row of stiff black hairs. Macrochaetae long, robust, black. Legs : black. Coxae with stiff black hair, femora with sparse fine brown hair below, spines and claws black and scales glistening black. Fore and mid femora unarmed, hind with three to four spines on the underside at the middle and one subapical one. Wings : hyaline. Veins brown, basal hook and vestigial basal comb black. Venation ; middle cross vein at basal third of discoidal cell, which is small and narrow, so that the posterior cells are long, contact of third and fourth posterior cells with discoidal cell about equal. Squama brownish at base, yellowish at margin, with a fringe of translucent white scales. Abdomen : black with glossy black scales and stiff black hair at the sides and across the hind margins of the tergites, except for the first which has white hair and two bands of white scales, a narrow one along the hind edge of the first tergite [on second according to Becker] and a broader one across the anterior third of the third tergite ; however the fourth to seventh tergites are badly denuded and there are traces of silver scales intermixed with the black ones. Sternites black, first four with opalescent whitish scales and brownish hair, remainder with glossy black scales and black hair. Ovipositor exposed, with five reddish spines on each side.

Thyridanthrax sp. ? argentifrons (Becker)

Three of the four female specimens from Abd-el-Kuri identified by Ricardo (1903) as Anthrax sp. have been examined. They are all badly denuded, rather faded and greasy, which makes certain identification impossible, but the general close resem- blance to the preceding species suggests that they probably belong to it or to a divergent subspecies developed in response to isolation on Abd-el-Kuri.

They differ from T. argentifrons females in that they are larger, 9-10 mm, the cuticle is not completely black but tends to have reddish areas, antennae dark reddish, the upper part of the pleura are densely covered in yellowish brown hair, the legs are dark reddish, the hair at the base of the abdomen is pale yellowish, the terminal abdominal segments show signs of extensive silver scaling and that the sternites are all covered in pale hair and silvery scales.

Thyridanthrax alatus (Becker) comb. n.

Hemipenthes alatus Becker, 1910 : 134.

The species was described from a single female and is represented by a female in the present collection. It is a pale-haired species with brown areas on the body and a shiny black vertex with indistinct ocellar tubercle, a combination of characters allying it with T. capella Greathead and T. pallescens Greathead, a species-group which seems, as far as it has been recognized, to be characteristic of the desert areas bordering the Palaearctic and Ethiopian regions (Greathead, in press).

Head : irons to region of antennae, and a triangular area between the antennae, genae and occiput black, lower parts red-brown, face conical, eye indentation barely indicated, bisecting line very short, vertex broad, three times the distance between the posterior ocelli in width, ocellar tubercle indistinct. Vertex glossy black, bare except for sparse black hairs, frons with sparse black hair on the black area and fine opalescent scales, face and pale parts with short yellowish hair and opalescent scales except for a tuft of short black hairs at the apex of the facial cone, occiput with short pale yellowish hair and also with opalescent scales. Antennae ; first segment red, remainder black, hairs on first and second segments black above, brownish yellow below, third broad, strap-like, tapering sharply to a minute style at the apex, twisted so that it is vertically flattened at the base and horizontally flattened at the apex. Proboscis projecting, labral part red, labial part black, palpi brown elongate with yellowish hairs. Thorax : black but with extensive brownish areas on the pleura, and scutellum red except for the extreme base. Hairs of collar and pleura pale white, tinged yellowish, dorsal surface denuded but showing traces of short golden brown hair and fine scales. Scales among the hairs at the sides of the dorsal surface white, tinged buff. Macrochaetae yellow-brown. Metapleura and hypopleura bare. Legs : black, except for upper surfaces of femora and coxae, which are brown. Hair and scales on coxae white, spines, spicules and scales on remaining parts black. Claws black with red bases. Wings : base, entire costal, basal and anal cells and marginal and discoidal cells to level of middle crossvein tinged pale yellow, remainder smoky hyaline. Veins yellow-brown. Upper branch of third vein straight at base and bent at right angles at the first bend. Discoidal cell truncate, the vein between it and the second basal cell long almost as long as the cell is wide at the wing margin, contact of discoidal and fourth posterior cells equal to that of the latter with the second basal cell. Basal hook brown, comb black with whitish scales. Squama and alula translucent yellowish with white fringes. Abdomen : black along the midline and bases of tergites, and sternites merging to red-brown on the remainder

giving the appearance of red-brown with an ill denned black median stripe. Hair on first segment and sides of basal half of second segment white, fine scattered hair on dorsal surface of segments 2-4 and hair rows at the margins of tergites on the dorsal surface black, those at the sides and on the apical segments yellowish ; scales at the bases of the tergites white gradually becoming yellow at the apex, however the pattern is difficult to distinguish as the specimen is rather denuded. Sternites with white scales and fine sparse yellowish hairs. Ovipositor red-brown with three weak spines at each side. Length of body n mm, of wing 9 mm.

Exoprosopa punctipennis Ricardo

(Text-figs. 6, 7) Exoprosopa punctipennis Ricardo, 1903 : 364.

This seems to be one of the commonest and most striking Bombyliidae from Sokotra. It is very similar in appearance to E. punctulata, a common and wide- spread species on the African mainland. It differs in being larger (10-15 rnm), more brightly coloured and heavily marked, in having dark-haired pleura, in that the abdomen is only obscurely reddish at the sides, and in that a short appendix juts into the discoidal cell from the recurrent angle of the vein separating it from the third posterior cell. None of these differences is an important character, and as it has spicules on the fore tibiae, like E. punctulata but unlike most other species of the genus, it is concluded that its resemblance to this species is one of close relation- ship and that E. punctipennis is probably derived from it. Ricardo (1903) draws attention to the appendix jutting into the discoidal cell from the vein dividing it from the third posterior cell. This character, like many minor instabilities of wing venation, does not invalidate the proposed relationship with E. punctulata, as an examination of a series of this species shows that this vein is variable in length and angularity and in the development of an appendix in one or both wings. Similarly E. disrupta (Walker) which also belongs to the E. punctulata group (Greathead, 1967^ ; E. disrupta also has spiculate front tibiae, a point not previously mentioned) shows a tendency to the development of an appendix into the discoidal cell.

Head : brownish black with a reddish buccal rim and a heavy red-brown tomentum. Face conical, its sides and base forming an equilateral triangle in profile. Eyes separated by three and a half to four times the width of the ocellar tubercle in both sexes. Eye indentation barely indicated, bisecting line very short. Hairs sparse, black on vertex, frons, face and under- side of head, on frons and face with scattered opalescent scales beneath, occiput with very short brown hairs and dense silvery scales at the posterior margins of the eyes. Antennae with first segment red-brown, two and a half times the length of the second, which is dull brown, shorter than wide, third dull brown, as long as first and second segments together, with a rounded base and tapering to an elongate red-brown style three-quarters the length of the third segment, style with a distinct spicule at its apex. Proboscis black shagreened, as long as the greatest length of the head, thus it is conspicuously projecting. Palpi black with fine black hairs. Thorax : black except apical two-thirds of scutellum, which is red heavily dusted with brown tomentum. Hair of collar above between notopleural stripes pale yellow, the hairs darker

yellow at their tips, sparse hair on dorsal surface, hair on pleura except upper parts of meta- pleural tuft, black, also with dense stripes of white scaly hairs along notopleura, upper part of metapleural tuft and plumula white. Scales on dorsal surface very sparse opalescent, macro- chaetae black. Legs : black including all hairs scales and spines. Fore tibiae spiculate, only hind femora with spines below, these with a complete row. Wings : base, costal cell, first basal cell, submarginal cell except broad apical part, basal half of submarginal and second basal cells, extreme base of first posterior cell, basal third of anal and base of axillary cell all infuscated chocolate-brown; also with chocolate-brown spots at the bases of the second and third submarginal, discoidal, second, third and fourth posterior cells. Basal hook and comb black, squama white, its fringe and fringe of alula also white. Venation with veins separating submarginal cells angularly bent, not smoothly curved, vein between discoidal and third basal cell long and contorted, bent twice almost at right angles into the third basal cell (thus giving a broad apex to the discoidal cell) and into the discoidal cell where a short appendix is emitted into that cell. Abdomen, <$ : conical, tergites black, obscurely reddish at the sides, first tergite with white hair except for a line of black hairs along its margin on the dorsal surface, second tergite with white hair at the sides of the basal two-thirds and with a narrow band of white

Exoprosopa insularis Ricardo

(Text-figs. 8, 9) Exoprosopa insularis Ricardo, 1903 : 365.

Ricardo (1903) compared this species with E. disrupta but as shown above E. dismpta is related to E. punctulata and E. punctipennis while E. insularis lacks the special characters of this group ; in contrast the front tibiae are not spiculate, the proboscis is short and the abdomen black, broad and flattened. Ricardo's other comparison with E. venus Wied. [sic], in fact E. venosa Wied. sensu Loew (described by Hesse, 1956, as E. leucothyrida), is more apposite. E. insularis has the highly contorted venation between the submarginal cells, narrowed first posterior cell, unstable venation tending to emit appendices either into the discoidal or third posterior cells and concentration of the infuscation along the margin of the veins, dark colouring and other body characters of species of the subgenus Acrodisca Bezzi. It seems to belong more properly with this grouping than with the E. punctulata group. As suggested by Bowden (1964) and accepted by Greathead (19670;), there is room for a regrouping of species within the genus, relying more on general similarities than single venational characters which are not always reliable. On this basis both E. insularis and E. leucothyrida belong in a grouping centred on Bezzi's subgenus Acrodisca.

Head : black with brown tomentum, brown around ocellar tubercle and in two stripes running from it to the antennae, genae and buccal rim yellow-brown. Sparse short hairs on occiput above, vertex, frons and face black. Hair at sides of occiput and fringing the posterior margin pale yellow. Scales on vertex and frons glossy black, on face mixed glossy black and dull gold, and on occiput dull gold. Eyes separated at vertex by three times the width of the ocellar tubercle, which is set forward of the narrowest point at the top of the head. Eye indentation straight-sided, shallow, so that the emargination is symmetrical and angular, bisecting line short. Facial cone triangular in profile, the apical angle being almost a right angle. Antennae ; first segment red with black hair, second black about half length of first with black hair, third slightly longer than first two segments together, upper surface straight, lower sloping upwards so that it is conical, with the apex over the circumference of the base, lower surface grooved, black above narrowly red below, style about two-thirds length of the third segment, black and

Thorax : black with brown tomentum and a paler median stripe of tomentum along the length of the scutum. Dorsal surface with sparse black hair and shiny black scales. Notopleural stripe and margin of scutellum marked by dull golden elongate scales.

SYNOPSIS

Thirty species of Thysanoptera are recorded from the Solomon Islands. Nine of these species are widespread across the world, two are widespread in the Western Pacific, two are known from other parts of Melanesia, and seventeen are known only from the Solomons. Fifteen new species are described, four new genera are defined, and seven new synonymies are established. The new species were collected in leaf-litter and a discussion is included on the structure, collecting methods and distribution of leaf-litter species.

INTRODUCTION

ONLY two species of Thysanoptera have been described from the Solomon Islands (Euoplothrips carcinoides Hood, 1937 and Mecynothrips snodgrassi Hood, 1952), and the present author has seen published records of only three other species from this area (Haplothrips priesnerianus Bagnall in Mound, 1968, and Thrips tabaci Lindemann and Selenothrips rubrocinctus (Giard) in Lever, 1968). In the present account a further twenty five species are recorded, of which fifteen are described as new, and notes are included of fragmentary material of several other species which have also been seen during the course of this work.

Most of the material discussed here was extracted from leaf-litter on the ground through berlese funnels, either by the government entomologist, Dr. John Greenslade (P.J.M.G.), or by Mr. P. N. Lawrence (P.N.L.) who visited the Islands with the Royal Society Expedition in 1965, or by collectors from the Bernice P. Bishop Museum, Hawaii. A single gall containing very large numbers of a single species was collected by Mr. J. Grant on the Royal Society Expedition, and three species were submitted for identification to the Commonwealth Institute of Entomology by the Solomon Islands Department of Agriculture. Unless stated to the contrary the material referred to in this paper is deposited in the British Museum (Natural History).

Thrips were extracted from moss, soil, leaf-litter and plant debris through eight- inch diameter plastic funnels. Several samples were taken at each site and these were placed in funnels beneath electric lights. The insects dropped into tubes of

alcohol pushed on to the bottoms of the funnels. The extractions were carried out at Kukum Agricultural Research Station, near Honiara, Guadalcanal, not at the various collecting sites, and Dr. Greenslade has suggested that at least some of the species were attracted either to the lights or to the alcohol of the funnels. This is probably true of some thripid specimens, but most of the Phlaeothipidae recorded here are apparently leaf -litter dwelling species and some were accompanied by larvae and apterae.

Because most of the species discussed here were extracted from leaf -litter, it is not possible to discuss the thrips fauna of the Solomon Islands in general terms. The few species known from surrounding areas were mainly collected from flowers or green leaves or dead wood, and these habitats have not been examined for thrips in the Solomons. Conversely the thrips of leaf -litter are unknown from Fiji and New Guinea, although some species have been described from Indonesia. However Moulton (1944) does not record the genera Ecacanthothrips, Machatothrips and Mecynothrips from Fiji, and in view of the large size of the species and the frequency with which they have been taken in the Melanesian area, it would be reasonable to expect collectors to find them if they were present. These forms may not extend across the Pacific, although Rhaebothrips is known from Formosa to Samoa and Eastern Australia. The apparent absence of the conspicuous flower-living Aeolo- thripidae from the Melanesian area is rather surprising, as this family is well developed in Australia and also occurs in New Zealand, New Caledonia and Southern India. Similarly no Merothripidae were taken in the Solomon Islands, although these inconspicuous thrips are readily taken in leaf-litter in Australia and also occur in New Zealand.

Some species that live in leaf-litter have a rather unexpected geographical range. Bradythrips hesperus is now known from Guyana, Southern India and the Solomon Islands, and species of the genus Psalidothrips are known from Java, the Solomon Islands and Brazil. The author has recently collected unidentified species of Allothrips and Pseudocryptothrips in Australia and both these genera occur in North America. These distributions may be natural but could be the result of man's activity. Leaf-litter thrips feed on the fungi associated with dead leaves and it seems likely that such fungi have extensive ranges. Unlike phytophagous insects which are limited by the range of their host plants, these fungus-feeding thrips have a continuous habitat wherever there are dead leaves and a suitably drained soil. However it is likely that man has also influenced the distribution of some species during the last three or four hundred years. The present author has commented elsewhere (1968 : 140) on the possibility that Nesothrips propinquus has been distributed around the Southern Hemisphere in hay used on board ships, and it is suggested below that Hoplandrothrips flavipes has similarly been distributed in firewood on ships. Lindroth (1957) in an account of the faunal relationships of North America and Europe has produced evidence to show that some species, particularly of carabid beetles, have been distributed by man in the soil and gravel used as ballast on sailing ships. Similar studies have not been made in tropical regions but ballast was carried by all sailing ships in varying quantities in order to

88 L. A. MOUND

maintain vessels at a suitable level in the water, thus more ballast was needed with a light cargo than a heavy cargo. Captain Cook records loading the Endeavour with eight tons of ' iron ballast ' before leaving England in 1768, but he also records taking on twenty tons of ' stone ballast ' at Tahiti, and unspecified amounts in New Zealand, Eastern Australia and Java (Beaglehole, 1955). Such stone ballast probably included quantities of soil and plant debris. In North Atlantic ports ships were not permitted to throw ballast into the water, as it could have blocked the harbour, but had to offload it on to the quayside. Similar regulations were probably in operation in tropical ports. Once the ballast was on the quay, it was then available to the next ship, so creating the opportunity for organisms to be moved in ballast from port to port. Although European settlers and plant collectors undoubtedly moved very large numbers of tubs of soil containing plants from place to place, this traffic in ships' ballast is probably more important to zoogeographers because of its sheer bulk. Lindroth (1957 : 161) states that according to the records of Poole Harbour in Southern England, 1180 tons of ballast were supplied to ships sailing from Poole to Newfoundland in the year 1815. With the vast tonnage of sailing vessels in operation during the eighteenth and nineteenth centuries there were thus ample opportunities for soil-living organisms to be moved around the world.

There are several morphological characters which seem to be associated with the leaf-litter habitat in the Phlaeothipinae. The species of Baphikothrips, Psalido- thrips, Mystrothrips and Solomonthrips are bicoloured, usually yellow with one or more transverse brown markings. The wings of most of these species are narrow, not constricted medially, with widely spaced cilia and few or no accessory cilia. Baphikothrips, Psalidothrips and Solomonthrips species have a narrow bell-shaped pelta as in Adraneothrips and Hoplandrothrips species. Surface reticulation is frequent in leaf -litter species such as Solomonthrips, Mystrothrips and the Glypto- thripini, but it is not restricted to such species nor are all leaf -litter species reticulate, e.g. Psalidothrips. An interesting negative characteristic is the apparent absence of oedymerous forms in these species. Fungus-feeding Phaleothripinae living under bark frequently show a very great range of body form, e.g. Ecacanthothrips. The leaf-litter species are also fungus-feeders but none of the species referred to here are known to produce strongly oedymerous individuals. The major males of Solomon- thrips greensladei described below have larger femora with tubercles than the minor males but they do not show any great difference in body size.

Most of the specimens referred to in this paper were treated briefly with 5% sodium hydroxide solution prior to dehydration and mounting in balsam. This treatment facilitates clearing but destroys the hypodermal pigments, and so the notes on colours of the species refer only to cuticular colour. The head lengths which are quoted are based on measurements of total head length from the base of the head to the interantennal projection. The text-figures were drawn at various magnifications, the heads and pronota using a Wild drawing tube and the remainder using a Zeiss camera lucida. Mr. B. R. Pitkin drew text-figures 10-12, 24, 25 and 28-32, and the others were drawn by the author. This paper could not have been

completed without the advice and generous loan of material from Dr. H. Priesner of Linz, Miss Kellie O'Neill of the U.S.D.A., Washington, and Dr. Paul Arnaud of the California Academy of Sciences.

THRIPIDAE

Included among the few thripids taken from leaf-litter were two female Scirto- thrips from Mt. Austen, Guadalcanal, one female Pseudodendrothrips from New Georgia, and four females and one male of the Thrips /Taeniothrips group from Guadalcanal and Kolombangara. The condition of these specimens was too poor for accurate study below the generic level at the present state of knowledge of the Melanesian fauna.

PHLAEOTHRIPIDAE

In addition to the species which are discussed below under the two subfamilies Phlaeothripinae and Megathripinae, a number of rather poor specimens have been seen which cannot be adequately distinguished. In the author's opinion, no useful purpose is served by describing species on inadequate material in unrevised genera which are known to include highly variable species. Two specimens of undescribed Androthrips and fifteen unidentified Haplothrips have been seen, also single speci- mens of Adraneothrips, Dicer atothrips, Horistothrips and Karnyothrips. Of more interest, but still not worth describing, were three specimens of a genus between Nesothrips and Dicer atothrips, and three specimens of a genus close to Malacothrips.

THYSANOPTERA FROM SOLOMON ISLANDS 91

This new genus resembles Baphothrips in many ways but in the opinion of the present author this is probably superficial. Baphikothrips is very close to Adraneo- thrips but has larger eyes, which are more extensive dorsally than ventrally, and moreover has the postocular setae rather close together. Adraneothrips and Baphikothrips both have a maxillary bridge, whereas in Baphothrips and Malaco- thrips the maxillary guides approach each other at their anterior ends as in more typical members of the Phlaeothripina (Priesner, 1960). It seems more likely that Adraneothrips and Baphikothrips are derived from Haplothrips-like stock by the loss of the praepectus and degeneration of the fore wings in association with their cryptic habitat, than that they have evolved from members of the Phlaeothripini and developed independantly a maxillary bridge. Moreover, these two genera, in common with Haplothrips, do not have antennal segment eight sharply constricted into a basal neck as is found in Baphothrips and Phlaeothripina such as Phlaeothrips, Ecacanthothrips and Hoplandrothrips. For these reasons the author would place Adraneothrips and Baphikothrips in the Haplothripini.

BAPHOTHRIPS Priesner Baphoihrips Priesner, 1933 : 69-70. Type-species : B. tricolor Priesner, by monotypy.

The unique female, from soil in Java, upon which this genus is based has been studied and compared with the new species described below. The genus may be defined as follows : —

Cuticle bicolored, brown and yellow ; wings weakly banded. Cheeks incut behind large compound eyes ; postocular setae long ; first ocellus directed forward between bases of antennae ; maxillary stylets close together in middle of head, maxillary bridge absent. Antennae long, eight-segmented, segment IV longest, VIII constricted at base ; three sense cones on III and IV. Pronotum transverse, epimeral sutures complete ; anteroangular setae rather close to midlaterals ; praepectus absent, mesopraesternum well developed but weakly sclerotized. Lateral mesonotal setae well developed. Metanotum reticulate, one pair of long setae wide apart near anterior margin. Fore wings moderately broad, weakly constricted medially, with accessory cilia ; three sub-basal setae in straight line. Pelta weakly sclerotized ; tergites II-VII with two pairs of wing-retaining setae and several lateral setae anterior to BI ; tergite IX with accessory seta between BI and 62 well developed, more than half as long as BI ; tube shorter than head.

This genus belongs in the Phlaeothripina close to Malacothrips, but most of the species placed in that genus are not known to the present author. Baphothrips apparently has larger, more rounded eyes, the cheeks are less constricted behind the eyes, and the maxillary stylets are retracted further into the head. Adraneothrips and Baphikothrips are readily distinguished by the presence of a maxillary bridge and the weaker fore wings. Moreover these two genera do not have the eighth antennal segment constricted into a basal neck and the pronotum is relatively longer.

Bagnall described the unique holotype of this species, which was dry on a card point, as having yellow antennae. This specimen has now been mounted into

THYSANOPTERA FROM SOLOMON ISLANDS 97

balsam and not only are the distal antennal segments brown but also segments three and four have light brown shadings near their apices. The antennae of inermis were also described as being yellow. Buffa's unique holotype has not been studied but the description does not separate it from spinipes, and as this species is apparently common in New Guinea, inermis is here regarded as a synonym. The unique holotype of bagnalli, which is a medium-sized male, and the type series of guinea- ensis, three very small females, have been studied and compared with the material listed below from New Guinea and the Solomon Islands.

This species can be distinguished from sanguineus Bagnall, the type-species of the genus, by the unarmed fore femora of the female and the broader reticulations laterally on the pelta (Text-figs. 5-7). The male has two subapical fore femoral teeth, a small and variable dorsal one overlaying the larger ventral tooth (cf. fig. in Priesner, 1930). However the species varies considerably in size, even within a population, and the smallest individuals can appear very different from the larger ones, as is known in sanguineus. In large females the fore femur bears a series of stout thorn-like setae on the inner dorsal surface, the fore tibia has about five tubercles on the inner margin, the sense cones on antennal segment three are dark, and the pelta has broad lateral reticulations. Medium-sized females are similar to the large ones, but very small females have no stout setae on the fore femur, no tubercles on the fore tibia, pale sense cones on the antenna, and the lateral margins of the pelta are eroded into small chitinous islets (Text-fig. 5).

There are four other nominal species of Ecacanthothrips with unarmed fore femora in the females. Neither piceae Ishida nor inarmatus Kurosawa from Japan have been studied, although according to the descriptions they are very similar to each other. The unique holotype of leai Moulton from Malaya, which is a very small female, has been compared with a rather large female paratype of coniger Priesner from Borneo, but because of the size-difference and the poor state of the leai holo- type, it is not possible to state how these species differ. From spinipes they differ in having the third antennal segment brown.

The holotype of gracilicornis from Nigeria has not been examined but the material listed below under this name was determined by Dr. Priesner. The characters given by Moulton to distinguish the Fijian species flavitibia from flavipes are not correct, and although the types have not been studied, the synonymy given by Ananthakrishnan is accepted here. Specimens determined by Dr. Ananthakrishnan as indicus have been studied but not the unique holotype of that name. Moulton (1947 : 175) has recorded a female of claratibia from Finschhafen, New Guinea ; Bianchi (1953 : 106) records both sexes from Samoa, and the species is here recorded for the first time from the Solomon Islands, Sumatra, and Malaya. There is no record of the species from the Neotropics but it is now known from Hawaii to West

THYSANOPTERA FROM SOLOMON ISLANDS 99

Africa. It probably feeds on fungus growing on dead wood and may well have been distributed round the world on the wood stored in ships as firewood. The Indian specimens listed below have fewer accessory wing cilia (6-8) than African or Solomon Islands specimens (10-12), and Moulton states that flavitibia has sixteen. The tubercle at the apex of the fore femur is not developed in very small males.

The species is placed in Hoplandrothrips rather than Phlaeothrips because the fore wings are weakly constricted medially. The antenna with the four fat sense cones on segment three has been figured by Ananthakrishnan, Priesner and Mound, and the following notes are intended to amplify the other descriptions.

Colour brown, median abdominal segments paler ; all tibiae, tarsi and femoral apices yellow, extreme base of mid and hind femora pale ; major pronotal setae dark ; wings weakly shaded, cilia dark ; antennals III, IV, V and sometimes VI shaded apically but much paler in teneral specimens. Head reticulate ; postoculars long, broadly expanded at apex ; vertex with about six pairs of fine submedian setae, cheeks with one pair of stout sub-basal setae ; stylets close in centre of head. Antennal III with four fat sense cones ventrally, IV with four stout sense cones. Pronotum reticulate near posterior margin particularly in large individuals ; pronotal setae long, expanded ; praepectus absent, mesopraesternum absent medially ; female with minute fore tarsal tooth, male with large tooth. Lateral mesonotal setae well developed ; metanotum reticulate. Pelta bell-shaped ; abdominal tergites with two pairs of wing-retaining setae ; tergite IX with BI and 62 more than two thirds as long as tube, weakly expanded at apex ; terminal setae as long as tube.

The following redefinition of this genus is based on a paratype of dammermanni from Java and the new species described below. According to Stannard, clavatoris Hood from Brazil, the only other species in the genus, has knobbed setae on the antennae and legs. The present author has taken at least one species of this genus in leaf-litter in Queensland, Australia.

Body strongly reticulate, all major setae broadly expanded except on antennae. Head longer than broad, concave at posterior dorsal margin, deeply incut behind eyes ; postocular setae short and expanded ; one pair of postocellar and mid-dorsal setae present ; cheeks tapering slightly to base of head, each with about five fine recurved setae ; maxillary stylets wide apart, retracted about halfway into head ; antennae eight-segmented, segments sculp- tured, three sense cones on III and IV, terminal seta longer than VIII. Pronotum reticulate, epimeral sutures complete ; anteroangular and midlateral setae about as far apart as the length of one seta ; praepectus very weak but apparently present ; mesopraesternum weakly sculptured, broadly boat-shaped ; fore tarsal claw slender, slightly curved, length equal to half the tarsal width. Mesonotum with lateral setae well developed, broadly expanded. Median setae of metanotum slender ; three pairs of basal wing setae with expanded apices. Pelta broad, reticulate, withdrawn into concave anterior margin of tergite II. Tergites II-VII with two pairs of sigmoid wing-retaining setae ; BI and 62 on IX long with broad round apices, BS acute ; tube faintly sculptured with overlapping scales, terminal setae shorter than tube ; sternites with a row of about twelve accessory setae, marginal seta BI shorter than 62.

$ (micropterous) . Colour yellowish, shaded brown on tergite II, at sides of head, apex of tube, and antennal segments I, II, VI-VIII and apical half of V. Head very similar to dammer- manni (see fig. in Stannard, 1955 : 101); postocellar setae fan-shaped, little smaller than postoculars ; sensorium on antennal II near apex (Text-fig, n). Tergites and sternites fully sculptured (Text-fig. 12) ; tube with faint sculpture, like overlapping scales.

Pronotum, length no ; width 270 ; epimeral seta 20 long, 13 wide at apex. Tergite IX, BI no ; 62 130. Tube, length 135 ; terminal setae 80. Antennal segments : 42 ; 50 ; 70 ; 68 ; 68 ; 58 ; 42 ; 42.

Holotype $. KOLOMBANGARA : near Kuzi, 1500 ft., leaf -litter in mossy wood,

Although this new species resembles dammermanni not only in the characters given in the generic definition but also in the colour pattern, it can be distinguished by the shorter, more broadly expanded, fan-shaped setae particularly on the head and pronotum. In dammermanni the postocellar setae are small with acute apices and the prothoracic epimeral setae about three times as long as broad apically.

PSALIDOTHRIPS Priesner

Psalidothrips Priesner, 1932 : 61-62. Type-species : P. amens Priesner, by monotypy.

This genus was erected for the species amens from Java, which was based on a single female, and the author is grateful to Dr. Priesner for the loan of this holotype. The following definition of the genus is based on a comparison of amens with the two new species from the Solomon Islands described below, but the other four species in Psalidothrips, described by Hood (1955) from Belem, Brazil, have not been studied.

Slender, weakly sclerotized, bicoloured thrips. Head as broad as long, cheeks rounded, narrowed to base, eyes well developed ; ventral surface with only one pair of long setae, arising between tentorial pits not at base of head ; postocular setae long, close to eye, postocellars

THYSANOPTERA FROM SOLOMON ISLANDS 101

about as long as ocellar traingle ; maxillary stylets not deeply retracted into head, without maxillary bridge ; maxillary palps very small, scarcely longer than labial palps ; mouth cone short and rounded. Antennae eight-segmented ; sensorium on II near apex. Pronotum with anteromarginal and anteroangular setae minute, posteroangulars about twice as long as epimerals ; epimeral sutures complete ; mesopraesternum complete, praepectus absent with cuticular islets arranged linearly in a regular pattern. Meso- and metanotum faintly sculptured, without major setae ; ventral thoracic setae minute. Fore femora thickened in both sexes, fore tarsus unarmed in female, with stout tooth in male. Fore wing cilia widely spaced, distal half of wing parallel-sided without accessory cilia ; two pairs of small sub-basal wing setae, BI minute. Pelta not constant in shape, margin frequently broken up into cuticular islets. Tergites II-VII with two pairs of wing-retaining setae, these setae curved but not sigmoid ; BI and 62 on IX almost as long as tube in both sexes ; terminal setae shorter than tube ; fustis of female short and weak. Sternal accessory setae less than iO[j. long, each sternite with less than six accessory setae ; sternite VIII of male with transverse glandular area ; sternite VI of male frequently with a pair of deeply reticulate areas.

Priesner originally placed this genus in the Haplothripini near to Adraneothrips. However the wing form of Psalidothrips is probably an adaptation to the leaf-litter habitat. The genus has subsequently been placed in both the Phlaeothripina and Mesothripina, but it is probably related to Sagenothrips, another Melanesian leaf- litter form, and should come into the Hoplothripina. Most Phlaeothripidae have a pair of long setae near the posterior ventral margin of the head, but in Psalidothrips these setae are short and there is a pair of long setae between the tentorial pits. The genus is also unusual in the small size of the maxillary palps and the anterior setae of the pronotum, as well as the few sternal accessory setae.

The three species in this genus known to the author may be distinguished by means of the following key. Unlike many fungus-feeding species of thrips, the two new species are remarkably constant in body size and the lengths of their major setae.

1 Antennal segments with lines of sculpture ; segments III and IV with two sense

cones ; maxillary stylets subparallel, retracted about half way into head ; head, antennae, mesothorax and abdominal segment II brown, rest of body yellowish,

Antennal sense cones shorter, on IV about one half as long as segment ; major setae acute or softly rounded at apex ; head pale medially, deeply shaded between eyes and along cheeks ; male macropterous . . . minor sp. n. (p. 103)

According to the descriptions given by Hood (1955) the four species from Brazil may be distinguished as follows ; dissidens and umbraticus have three sense cones on antennal III and four on IV, and dissidens is almost uniformly brown ; retifer has three sense cones on both III and IV but the head is reticulate all over ; con- ciliatus has two sense cones on III and IV as in grandisbut the segments are apparently not reticulate and the sense cones are more than half as long as the segments.

Although the females of this species are macropterous, many specimens had the distal half of the fore wings broken. This condition was so common that it is possible the wings are broken naturally in the field.

In the larva the anterior margin of the pronotum bears very small setae as in the adult.

SOLOMONTHRIPS gen. n.

Type-species : Solomonthrips greensladei sp. n.

Small slender species, light brown or frequently yellowish with brown markings, metanotum and at least part of head reticulate. Usually macropterous but micropterous and hemimacrop- terous individuals found. Antennae eight-segmented, almost moniliform, VIII always distinct, usually constricted at base ; two sense cones ventrolaterally on III and IV, sensorium on II near apex ; apical seta on VIII very long, usually longer than VII -f- VIII. Eyes well developed, cheeks sharply incut behind eyes without major setae ; vertex reticulate at least in part, postocular setae well developed ; mouth cone short and rounded apically, maxillary palps small ; stylets deeply or barely retracted into head, usually with maxillary bridge.

Pronotum transverse, weakly sculptured, epimeral sutures complete ; only four pairs of major setae present, anteroangulars (? or midlaterals) absent, posteroangulars not close to epimeral sutures ; major setae broadly expanded apically. Mesonotum reticulate, without major or elongate setae. Metanotum with elongate triangular band of reticulation, median setae not enlarged. Praepectus present, sometimes weak ; probasisternum large and pig- mented ; mesopraesternum not small but weakly sclerotized. Fore femora moderately en- larged, sometimes with indistinct irregular hump on inner margin ; fore tibiae unarmed in female ; fore tarsi armed in both sexes. Fore wings weakly expanded at base, distal two thirds slender and parallel-sided ; cilia widely separated except around apex, no duplicated cilia ; third sub-basal wing seta distant from one and two.

Pelta reticulate, bell-shaped ; tergites III to VIII with two pairs of wing-retaining setae, only one wing-retaining seta on tergite II ; tergites laterally frequently with sculpture. Setae on tergite IX shorter than tube, BI and 62 expanded apically ; terminal cilia of tube short

Although superficially resembling both Malacothrips and Adraneothrips, this

io6 L. A. MOUND

new genus can be distinguished from them both by the presence of the praepectus. Mystrothrips is also similar but has three sense cones on the third and fourth antennal segments, and has the lateral mesonotal setae well developed. The thoracic chaetotaxy of Solomonthrips is unique and moreover the development of wing- retaining setae on the eighth tergite is unusual. However the genus is probably derived from a genus like Sagenothrips. The author has examined the unique holo- type of Sagenothrips gracilioornis through the courtesy of Dr. Priesner, and this specimen has no major mesonotal setae and the third sub-basal wing seta is more than twice its length from the second. The pronotal anteroangular and midlateral setae are very reduced, less than ion l°ng- Contrary to Stannard (1955 : 79) the anteromarginal setae are present, i6ji long, the right hand one being displaced submarginally and the left hand one partially obscured by the pigment of this imperfectly cleared individual. Although the heads of both genera are more or less reticulate, neither Sagenothrips nor Solomonthrips belong in the Glyptothripini. The reticulation of the body and the weak structure of the wings are probably functional adaptations to the leaf -litter habitat.

KEY TO THE SPECIES OF SOLOMONTHRIPS

1 Tergite VIII with BI not large and expanded as on tergite VII but acute and curved,

closely parallel to marginal wing-retaining setae (Text-fig. 24) ; fore femur in both sexes with irregular hump on inner margin (Text-fig. 23) ; major males with subapical fore tibial spur (male not known in striatus) ; two pairs of long ventral interocular setae, as long as antennal III ....... 2

Tergite VIII with chaetotaxy closely similar to tergite VII, BI major straight with expanded apex (Text-fig. 25) ; fore femur without an irregular hump on inner margin, male without a subapical fore tibial spur ; ventral interocular setae not as long as antennal III although sometimes longer than remaining ventral head setae .............. 3

2 Sternal reticulations on V-VII anterior to median row of accessory setae with internal

longitudinal striations (Text-fig. 30) ; median area of vertex between postocular setae clearly reticulate (Text-fig. 20) ; antennal III much paler than IV, head without median longitudinal dark stripe ..... striatus sp. n. (p. 113) Sternal reticulations without internal longitudinal striations ; median area of vertex between postocular setae without sculpture or with very faint reticulations (Text- fig. 19) ; antennal III not much paler than IV, head usually with median longitudinal dark stripe greensladei sp. n. (p. 107)

3 Antennals III and IV with dorsal setae expanded apically (Text-fig. 27) ; head fully

reticulate both dorsally and ventrally (Text-fig. 22) ; ventral interocular setae no longer than remaining ventral head setae ; probasisternum fused into single plate ; abdominal sternites with more than twelve long accessory setae ; major body setae very broadly expanded, lateral abdominals almost as broad as long ; maxil- lary stylets barely retracted into head, maxillary bridge absent . setifer sp. n. (p. in) Antennal segments with major setae acute ; head not fully reticulate ; ventral interocular setae longer than remaining ventral head setae ; probasisternal plates separate ; abdominal sternites with accessory setae small, less than a quarter as long as sternal marginals ; lateral abdominal setae longer than width of apical expansion ...... ...... 4

width ; major setae short with expanded smooth apex, basal wing setae less than half basal width of fore wing ; tergite IX setae BI rather short, two thirds of B2.

intertnedius sp. n. (p. no)

Upper surface of head not sculptured between postocular setae but with transverse band of reticulations at base (Text-fig. 21) ; stylets low in head, maxillary bridge more than half of head width ; major setae long, expanded apices fimbriate, basal wing setae more than half basal width of fore wing ; tergite IX setae BI more than two thirds as long as 62 ....... fimbrii sp. n. (p. no)

The development of the major seta BI on tergite eight as an additional wing- retaining seta in greensladei and striatus is not always complete. Although weak and sigmoidal in all the specimens studied, this seta in a few individuals is very weakly expanded or " soft " at the apex instead of acute. The characters given in the key suggest that setifer is quite distinct from the other species, but it appears to be merely an extreme specialization within the group. The probasisternal plates are large and heavily pigmented in the other species and so their fusion in setifer is not particularly surprising. Similarly the placement of the maxillary stylets and the extent of the reticulation on the vertex is variable between the other species and the condition in setifer can be regarded conveniently as an extreme of a series.

Solomonthrips greensladei sp. n.

(Text-figs. 19, 23, 24, 26, 34, 35)

The specimens on which this species is described are variable both in colour and the lengths of some major setae. These specimens were collected at several different sites in the Solomon Islands and although the two main colour forms were collected together on both Guadalcanal and Kolambangara there is a possibility that local populations may eventually be found to be specifically distinct. For this reason a male has been selected as holotype, and this individual is weakly oedymerous and has the aedeagus exposed (Text-fig. 35).

<J (macropterous) . Colour yellowish, thoracic sternites and coxae brown, head with lateral margins and median longitudinal stripe brown ; antennae light brown, darkening distally ; fore and hind wings and major setae shaded ; mid and hind tarsi yellow, rest of legs variable pale brown ; abdominal segments weakly shaded posterolaterally, tube darker apically.

Head reticulate at base, weakly sculptured medially (Text-fig. 19) ; maxillary stylets low ; antennals III, IV and V with two ventrolateral sense cones, a small dorsal sense cone on V (Text-fig. 26). Pronotum wider than long, weakly scupltured medially (Text-fig. 19), epimeral sutures complete. Fore femora weakly incrassate, interior margin with indistinct rugose hump, fore tibia with apex thickened or with a spur in major males, fore tarsus with stout claw (Text-fig. 23). Mesonotum reticulate near posterior margin, without long or expanded setae. Metanotum reticulate medially with one pair of weak setae near anterior margin. Fore wing typical of genus.

Pelta longer than wide, weakly reticulate (Text-fig. 34) ; tergites III-VIII with two pairs of wing-retaining setae, the posterior pair much stouter than the anterior pair on anterior seg- ments ; major seta BI on tergite VIII fine and curved, usually with acute apex, parallel to wing-retaining setae (Text-fig. 24) ; BI on tergites II-VII with broadly expanded assymetric apex, sculpture anterior to BI with stout dentate microtrichia, tergites weakly reticulate medially ; BI on IX shorter than or sub-equal to B% with moderately expanded apex, B2

Paratype $ hemimacropterous and 3 larvae, SAN CRISTOVAL : 6 miles S.E. of Wainoni, in moss-forest litter at 2325 feet, 3.viii.i965 (P.N.L.).

This species is very similar to greensladei although the sternal reticulations are apparently quite distinctive. These striations may not be evident in specimens that have not been fully cleared however.

Larvae taken with this species are very similar to larvae taken with greensladei but have abdominal segment nine all brown, the head and pronotal shield bear minute microtrichia, and the major setae are shorter and more broadly expanded at the apex.

SOPHIKOTHRIPS gen. n.

Type-species : Sophikothrips malaitae sp. n.

Head small, broader than long ; eyes large ; postocular setae absent ; stylets retracted into base of head ; antennae eight-segmented, III with three sense cones, IV with four. Pronotum twice as long and twice as broad as head ; praepectus very weak, mesopraesternum absent ; fore tarsus with tooth ; fore wing without accessory cilia ; major setae short, apices expanded. Pelta divided into a small dark anterior portion and a transverse poorly defined posterior sclerite ; sternites with no accessory setae ; tergites with one pair of straight wing-retaining setae ; tube as long as head, apical setae shorter.

Nine species have been described in the genus Sophiothrips Hood, and some authors place Nanothrips Faure with three species and Zaxenothrips Crawford with one species in synonymy with this genus. Seven of the Sophiothrips species were described as having two long dorsolateral sense cones on antennal segments three and four, although both bicolor and vorticosus apparently have only one sense cone on segment three. The species included in Zaxenothrips and Nanothrips are des- cribed as having one sense cone on segment three and two on four, and these sense cones are shorter than those found in the other species. Eleven of these thirteen

114 L- A- MOUND

species have well developed interocellar setae and a laterally displaced stout post- ocular seta ; however 5. vorticosus is described as having small postocular and interocellar setae, and N. breviceps is figured as having three small pairs of postocular setae. The small head and wide pronotum may be an adaptation to the leaf-litter habitat. The new species described below, although similar to this group, has three long sense cones on antennal segment three and four on segment four, no postocular setae except a minute one on the cheek, and moreover the maxillary stylets are not restricted to the mouth cone.

Allotype (J and numerous specimens of both sexes and immature stages taken with the holotype (69 $ $ and 16^,^ mounted on slides).

The gall in which this species was collected was spherical, about six inches in diameter, composed of a solid mass of highly convoluted non- woody tissue. This is apparently the largest gall caused by thrips which has been recorded. Only one species has been found in the gall but there may be 10,000 individuals in this single colony. The body size was found to be remarkably constant.

The leaf-feeding Phlaeothripinae of the Melanesian region are poorly known and the generic classification of this group is rather difficult to interpret. The type- species of Eothrips is not known to the present author but annulicornis Karny has

n6 L. A. MOUND

been studied and this genus apparently is distinct on account of the striate metano- tum, long sense cones, and unarmed fore tarsi of the male. The new species granti cannot be placed in Teuchothrips or Gynaikothrips (sensu strictu) on account of the short head and reduced eyes, and moreover the short-headed Gynaikothrips citritibia Moulton, 1940 from New Britain should be placed in Eothrips (comb. n). In citritibia, of which the author has recently studied the holotype and allotype, the sense cones on antennals III and IV are three quarters as long as the segments, and the fore tarsus of the male does not have a tooth. Similarly granti cannot be placed in Eugynothrips as the species of that genus have long sense cones and short anterior pronotal setae.

The antennae, the sculpture and the chaetotaxy of granti are very similar to smilacis Priesner, which is a common species, rolling the leaves of a climbing plant Smilax australis in Eastern Australia. This is the only species at present placed in the genus Tolmetothrips Priesner, 1953. In smilacis the maxillary stylets are wide apart, low in the head and the eyes are not so reduced as in granti.

Priesner (1960) places the leaf-feeding, gall-forming species of the Gynaikothrips I TeiichothripsjLiothrips complex in the same subtribe as the fungus-feeding species of Hoplothrips. In the opinion of the present author, Hoplothrips can be dis- tinguished from the leaf-feeding forms not only by its biology but also by the greater number of sense cones on the third antennal segment and the constricted neck at the base of segment eight. In these respects this genus is similar to the genera around Hoplandrothrips, and Hoplothrips is probably a reduced and highly successful offshoot from the fungus-feeding Phlaeothripina.

This is the second species to be included in the genus Atractothrips. It differs very considerably from bradleyi Hood, 1938 from Panama, and may eventually have to be placed in a separate genus (see Stannard, 1957 ; 93-94). Four paratypes of bradleyi have been studied and that species differs from solomoni as follows :

Antennal segment II with sensorium and two stout setae at apex ; sense cones on III minute ; antennal segments long and slender, dorsal setae small and acute ; lateral ocellar setae long, interocellars small ; eyes reduced, angular in outline ; postocular setae not distinct, dorsal surface of head with about 10 pairs of setae ; pronotal midlateral setae very small, close to anteroangulars ; three small setae along anterior margin of epimeral suture ; praepectus absent ; fore tarsi unarmed in both sexes ; basal wing setae absent ; anterior angles of meso- thorax projecting ; lateral metanotal sclerite with large expanded setae ; tergites with three pairs of setae at margin including wing-retaining seta and posteroangular seta ; median tergal setae and pores large ; tergites sculptured in front of antecostal ridge ; tube very long ; BI on IX about one quarter as long as segment ; sternal accessories not in a regular transverse row.

Females in this genus have a series of tubercles on the fore femur although these are not present in the males. Because the type-species of Adiaphorothrips is the male of the type-species of Machatothrips, several species which were described in Adiaphorothrips, particularly from Australia, are now referred to the older genus although they do not belong there. The following species are at present placed in Machatothrips.

One paratype of spatiata from Dr. Priesner 's collection has been studied and compared with the type specimens of haplodon. M. isshikii is not recognizable as a member of this genus from its description. The species artocarpi, celosia, heveae and montanus are not at present clearly denned, and the unique holotype of celosia has not been studied, although type material of all the other species has been used in the preparation of the following key.

The statement in the original description that the mid-dorsal head setae are ' very small, hardly one fourth the length of postoculars ' is not correct. In the holotype these setae are almost erect but their length has been calculated by using a microscope with the vertical movement calibrated in microns. The mid-dorsal setae are about Son and the postoculars i8ou.

The species is apparently widespread in the Western Pacific, but as indicated above it is not clearly different from heveae or montanus. The females from the

Species of Mecynothrips are also known from New Guinea, Kei Islands, Manus Island, New Britain and Eastern Queensland. The genus has recently been revised and snodgrassi, which is only known from the Solomon Islands, can be distinguished by the apical expansion of the fore tibia lying parallel to the fore tarsal claw.

OMMATIDOTHRIPS gen. n.

Type-species : Ommatidothrips lawrencei sp. n.

This genus is erected for a species in which the head is strongly sexually dimorphic, but in which both males and females have an area of clear cuticle on each cheek posterior to the compound eyes, apparently representing a single isolated ommatidium. Eyes of this type have not previously been described in the Thysano- ptera, but apterous females of a second species of this genus have been collected by the author on dead grass in Northern Queensland, Australia.

Large brown, non-sculptured species, feeding on fungal spores. Head long, dorsally elevated, eyes rather small, with one ommatidium separate on each cheek ; cheeks convex with stout spines in male, weakly concave with fine setae in female ; postocellar and postocular setae long ; stylets approach each other in middle of head, mouth cone rounded with large maxillary palps. Fore tarsus armed in both sexes ; wings, when present, of equal width with few accessory cilia. Pronotum emarginate anteriorly, anteroangular setae not arising at margin ; epimeral sutures complete, praepectus present. Tube almost as long as head, with many fine setae ; both sexes with B2 on tergite IX less than half as long as BI ; abdominal tergites with one pair of wing-retaining setae.

The relationships of this new genus within the Megathripinae are not clear. The long head with the maxillary stylets approaching each other medially suggests Megalothrips, but in that genus there is a stout seta on the cheek behind each eye

and the males have a pair of drepanae on abdominal segment six. The new species is unusual in the subfamily in having the seta 62 on tergite nine of the male less than half as long as BI, and in this character it resembles Abiastothrips. Several genera which Priesner (1960) places in the Cryptothripina are regarded by Stannard (1957) as being quite unrelated and as belonging in the subfamily Phlaeothipinae. Certain of these genera have the head elevated in the midline and do not have three equally long pairs of setae on tergite nine in the males. The present author considers that at least Abiastothrips belongs in the Megathripinae, near to Crypto- thrips, and it is to these forms that the new genus is most closely related.

Rhaebothrips lativentris Karny

Rhaebothrips lativentris Karny, 1913 : 128-129.

The genus Rhaebothrips was erected by Karny for the species lativentris, based on a single male from Formosa. Two further species have been described in the genus, major Bagnall, 1928 from Samoa, and fuscus Moulton, 1942 from Guam, Fiji and the Torres Straits. Karny (1924) recorded lativentris from Queensland, and there are specimens determined as that species by Karny in Dr. Priesner's collection from Ponape. Moulton (1944) recorded major from Fiji but did not refer to his species fuscus in that paper, although his remarks on the variation in major would appear to include fuscus as a variety. The unique holotype of major is lost (Mound, 1968), but Bianchi (1953) states that Moulton's specimens from Hawaii and Fiji can be separated from new specimens available from Samoa.

At present it is not possible to be certain of the specific identity of the Solomon Islands representatives of this genus, but it seems that there is just one widespread species involved. The specimens from Ponape mentioned above vary greatly in size, both within and between sexes. In the specimens listed below, it has been noted that the tube is shorter than the head in micropterae but longer than the head in macropterae. However the tube is relatively longer in males than in females.

SYNOPSIS

The African genus Catoptropteryx Karsch is fully revised and a key is given to the species. Three specific synonyms are newly established and seven new species are described.

INTRODUCTION

KARSCH erected the genus Catoptropteryx in 1890 for a single new species, C. guttatipes, from Cameroon. In 1896 he described a further six new species and suggested that closely related to these were three of the four African species described in Caedicia Stal, of which, however, he formally transferred only Catoptropteryx afra (Karsch). Kirby, in his catalogue of 1906, listed eleven species of Catoptropteryx Karsch and included all the African species of Caedicia Stal. No new species has been recorded since 1896, with the exception of C. latipennis Chopard, 1955, which is considered here to belong to another genus (see below). Although up to the present time the genus Catoptropteryx Karsch has been remarkably homogeneous and easily recognized, there has always been considerable difficulty in the separation of the species. The present work, while attempting to remove this difficulty, inevitably extends the morphological and geographic boundaries of the group, making it more heterogeneous and less readily characterized. Over 1200 specimens have been examined, including all the type material. Seven new species are described, three specific synonyms are newly established and lectotypes are desig- nated for C. signatipennis Karsch and C. neutralipennis Karsch. In the course of examining the ovipositor as a source of taxonomic characters it was necessary to homologize its parts in order to establish a terminology generalized enough for use in taxonomic studies on other Tettigoniidae.

Catoptropteryx latipennis Chopard, as mentioned above, is incorrectly placed in this genus and is removed from it by the following synonymy, based on an examina- tion of the type-specimens :

REVISION OF CATOPTROPTERYX 131

TREATMENT

It has been found necessary in attempting to provide a reliable means of identifica- tion of the species of Catoptrapteryx Karsch to make use of a few characters hitherto not commonly employed in taxonomic work on the Tettigoniidae. One class of characters that may deserve comment is that based on the coloration of the integu- ment. Many workers still tend to regard colour characters as unreliable in the sense that they are so often subject to individual variation as to be of dubious value in differentiating the species. However, the level of significance of differences in coloration, as with any other type of structural difference, varies from group to group, and there is no doubt that within this genus alone a particular feature of the colour pattern may show a consistent difference between a certain two species while in other species the same difference is embraced by intraspecific variation. In using the present revision, therefore, where a colour character is in the same state in all the examined material of a species, the value of this should not be under- estimated but assessed as a function only of the number of specimens on which the description is based.

Much work has been done, especially in recent years, on the acoustic behaviour of Orthoptera and the high taxonomic significance of song patterns is widely recognized. However, although the nature of sounds produced by Ensifera is clearly dependent in part on the structure of the stridulatory organ, and although this structure can be fairly readily examined in dead specimens, very little use has been made of this as a source of characters in systematic work on the group. The present work makes use of the three most easily examined attributes of the stridula- tory file, namely its gross appearance, length and number of teeth. The drawings of files were made from stained and cleared preparations of actual specimens, using a microprojector. The measurement of tooth number and file length was made on nitrocellulose replicas of a subsample of each species. The technique for making the replicas was essentially that described by Ragge (1969 : 172). A drop of 5% ammonia solution containing a trace of detergent as a wetting-agent was used to relax the wing base. To obtain sufficiently robust replicas from this genus it was necessary to coat the whole of the proximal centimetre of the ventral surface of the wing. The replicas were examined by diffuse transmitted light. ' Tooth number ' (T) includes all the teeth, however rudimentary, that can be discerned under the low power (xioo) of a microscope. ' File length ' (F), which was measured using a screw micrometer eyepiece, is the linear distance between the first and last tooth. The measurements made on replicas do not differ significantly from those made on the wing itself. Both tooth number and average tooth density (T/F) were found to be useful characters. The interspecific and infraspecific variation in these variates is shown in the scatter diagrams of tooth number on file length (Text-fig, i). In any one species, there is a broad correlation between tooth number and file length, as might be expected, but for the genus as a whole there is no such significant correlation owing to the large variation of average tooth density between species. For example, the sample mean of this last variate is 24-56 (teeth per mm) for C. aurita sp. n. and 63-51 for C. nanus sp. n., producing widely separated clusters of

points for these two species. While there is of course considerable overlap, lor the samples plotted each species does have a characteristic distribution of points and many pairs of species can be clearly differentiated by simultaneous consideration of tooth number and file length.

Although the form of the ovipositor valves is frequently used in the systematics of the Phaneropterinae, little use is made of the more complex assembly of sclerites at their base. This constitutes a mechanism for the control of the movements of the valves, in particular during oviposition, and its structure probably relates closely to oviposition behaviour. This aspect is peripheral to the present study except insofar as it is suggested that the form of the basal mechanism, like that of the valves themselves, is likely to be maintained within narrow limits of variability, and for this reason may be expected to provide reliable characters for the identifica- tion of the species. The shape of the basal sclerites is complex in many Phanerop- terinae, and almost always so in those genera, like Catoptropteryx Karsch, in which the valves are abnormally small, and whatever the functional significance of the form may be its variation from species to species is often discrete and readily per- ceived. Too commonly in the Tettigoniidae the males of a group of species may be easily distinguished by clear differences in their genitalia, while identification of the females relies heavily on their topographic association with identifiable males. In many such cases study of the basal mechanism of the ovipositor reveals good specific characters, and on the assumption based on this observation, that further use will be made of this structure in future work on phaneropterine taxonomy, I have considered it advisable to establish a morphological nomenclature at once rather than lay the foundation of a confusing diversity of terms by constructing an ad hoc terminology on a purely descriptive basis. Apart from the retention of the terms ' dorsal valves ' and ' ventral valves ', already commonly used and un- ambiguous in meaning, in preference to ' gonoplac ' and ' first gonapophysis ', the ovipositor is described using the nomenclature of Scudder (19610, 19616, 1964). Scudder and Harz intend to propose the terms ' supragonangulum ' and ' infra- gonangulum ' for the anterodorsal and posteroventral divisions of the gonangulum of the Tettigoniidae (Scudder in lit.} and I am anticipating the publication of their work by adopting these terms here. The structure, interrelationships and homologies of the sclerites of the ovipositor of Catoptropteryx Karsch were determined by examin- ation of examples of all the species well represented in the available material. The abdomens of dried specimens were macerated in 10% potassium hydroxide and studied under isopropyl alcohol and in cleared and stained slide preparations. The results of this investigation are summarized diagrammatically in Text-fig. 2. The most useful specific differences in the basal mechanism are to be found by examining the form and relative sizes of the lobe of the infragonangulum (iga) and the first gonocoxa (gc i), and the spatial relationship of these sclerites to each other. The supragonangulum (sga) and second gonocoxa (gc 2) also show specific differences but these tend to be less well defined and the sclerites are not always so readily examined in dried material. The subtlety of shape of the ovipositor parts makes verbal diagnosis difficult and this has therefore been minimized in the species

descriptions, reliance being placed almost entirely on the text-figures for comparison of ovipositor characters. When comparing specimens with the text-figures it is essential to bear in mind the possible effects of a number of factors, the operation of which leads to a misleading diversity in the appearance of ovipositors of the same species. All the drawings have been made from dried specimens in which the process of drying causes variable distortion of sclerites, variable lateral displacement of the subgenital plate, and variation in the degree to which the anterior part of the basal mechanism is concealed by the ninth and tenth abdominal tergites. Further, as the ovipositor in life consists of a system of moving parts, the positions of the parts relative to one another are subject to variation ; for example, in Text-fig. 2, anticlockwise rotation of the plate formed by the fused gonangulum and first gonocoxa would result in an anterior displacement of the second gonocoxa and dorsal valve, posterior displacement of the ventral valve, and partial concealment of the supra- gonangulum beneath the ninth abdominal tergite. This sort of change produces an unexpectedly large diversity in the gross appearance of the ovipositor.

Every species description includes the ranges in the material examined of certain linear measurements commonly found to be useful in tettigoniid taxonomy at this level. All measurements are given in millimetres. Means are not given for two reasons : the samples are extremely heterogeneous and the relative contributions of geographic and intrapopulational variation to the value of the mean are not

assessed ; even in a (biologically) homogeneous sample knowledge of the mean alone, with no estimate of the variance or skewness of the distribution, is not very useful. Measurements were made using calipers, with the exception of the file length (see above) and the median length of the pronotum, for both of which a screw micrometer eyepiece was used. ' Total length ' means the distance from the most anterior part of the head (excluding its appendages) to the tip of the flexed hind wings. ' Length of fore wings ' is the distance from the distal margin of the second axillary sclerite to the apex of the wing, and is conveniently measured by inserting one point of the calipers into the small notch in the wing extending distad from this sclerite.

In descriptions of the legs and antennae the terms ' internal ', ' external ', ' dorsal ' and ' ventral ' refer to these appendages in standard positions, the antennae and fore legs directed forwards and the mid and hind legs directed backwards.

The wing- venation is described using the nomenclature of Ragge (1955). The veins used in the diagnosis of Catoptropteryx spp. are illustrated and named in Text- fig. 65.

TAXONOMIC STRUCTURE

It may be necessary to stress that throughout this paper, where expressions such as ' affinity ' and ' related ' are used without qualification no phyletic meaning is intended, such terms referring only to the degree of morphological resemblance observed. Whether phyletic information can be inferred from the evidence of the few morphological characters studied in this revision is another matter.

Text-fig. 3 is a schematization of the affinities of the species of Catoptropteryx Karsch based on an intuitive selection of characters from the ovipositor, fore wing venation, eyes, tympanic organs and male cerci. It is not based on a rigorous phenetic analysis but is merely an attempt to give visual form to a largely subjective assessment of the relations among the species. It can be seen that the genus falls into three principal species-groups comprising respectively i) extensipes, 2} aurita and serrifera, and 3) the remaining twelve species. The second group is linked to the third both morphologically and geographically by C. serrifera sp. n. The third and largest group subdivides itself fairly readily into the following three subgroups : i) nanus, ramulosa, capreola and naevia ; ii) apicalis, afra and neutralipennis ; iii) ambigua, nigrospinosa, punctulata, guttatipes and occidentalis. Of these, ii) and iii) are strongly linked through C. neutralipennis Karsch.

C. aurita sp. n. is the only species in which the internal auricle of the tympanic organs is at all developed. Although in the Phaneropterinae this most commonly has the status of a generic character, the inclusion of C. aurita sp. n. in this genus, with the consequent heterogeneity of the latter, is justified by the observation that C. serrifera sp. n., which has no tympanic auricles, is rather more closely related to the auriculate species than it is to the rest of the genus. I can find no real justification for the attachment of special taxonomic significance to the difference in the tympanic organ of these two species. Morphogenetically, the difference might readily be assumed to be trivial in that the auriculate form could be simply derived from the

136

J. HUXLEY

open form by a slight expansion of the ventral internal rim of the tympanic opening. The reverse transformation is equally feasible. A decision as to which may be the primitive and which the derived form of this structure might be of some biogeo- graphic interest, as the auriculate species is the only one with an East African distribution. This decision clearly cannot be based on the kind of evidence available here. However, one purely speculative possibility is that the auriculate form is primitive and the open form derived from it. It might be supposed for example that in an environment in which predation pressure is high, selection would favour reduction of the auricle to give completely open tympana, which could be the more

efficient condition for nondirectional defence responses. If, moreover, the population density were high, reduction of mating efficiency by a reduction of the efficiency of directional responses to acoustic stimuli might not be a dominant selective factor. On the other hand, under conditions of low predator density and sparse populations, directional response capabilities may be favoured over nondirectional, and the auricle retained.

BIOLOGY

Nothing has been published relating to the biology of any of the species of Cato- ptropteryx Karsch. Moreover, since all the properly documented material examined was collected in light-traps, I have virtually no evidence in respect of ecological information. Enquiries made of collectors have not enabled any conclusions to be reached on this issue. The collecting localities almost all lie within areas of moist lowland forest or forest-savanna mosaic and several collectors suggest that it is likely to be a forest-dwelling genus. Dr. M. C. Eluwa, formerly of the University of Ibadan, however, has suggested (in lit.) that the principal habitat of the genus may be the bushes characteristic of farm lands. A few of the specimens examined had feculae attached and microscopic examination of these has revealed plant material only, without any trace of animal parts. In his laboratory Dr. Eluwa has fed specimens of an unidentified species of Catoptropteryx Karsch with tender leaves of Ficus sp. The dense sensory bristles of the valves of the ovipositor and their lack of teeth in the majority of species indicate that eggs are not usually deposited within plant tissues, and the small size of the valves argues against the use of deep crevices in soil or bark as oviposition sites. Dr. Eluwa supports this deduction with a single observation of oviposition in the laboratory. A row of 29 eggs was deposited along a vein on the abaxial surface of a Ficus leaf (see Plate i, fig. i).

All spurs and spinules blackened, at least apically.

While Catoptropteryx Karsch is rather easily recognized (see Plate i, figs. 2-3), it is not easy to make a brief list of diagnostic features distinguishing it from its closest relatives. It resembles quite closely Caedicia Stal from which it seems to be principally distinguished by its more globular eyes (or very much larger eyes in the case of C. extensipes Karsch) and less prominent antennal scrobes. Confusion of these genera is in practice unlikely as Caedicia Stal has an Australian and Austro- oriental distribution. Dapanera Karsch, however, is extremely similar and has a similar distribution to Catoptropteryx Karsch. The former genus may be dis- tinguished by the fore wings which are broader and have a denser, more opaque archedictyon, by the well developed ovipositor, and (except from C. aurita sp. n.) by the auriculate inner tympanum. The most useful characters distinguishing the species of Catoptropteryx Karsch are undoubtedly to be found in the basal mechanism of the ovipositor (see p. 133), the male cerci and stridulatory organ (see p. 131) and the coloration of the fore wings and pronotal lobes (see p. 131). It is essential, however, for reliable determination to take into account all the characters treated in the diagnostic descriptions.

The distribution of the genus falls into two distinct areas of tropical Africa (see Text-fig. 4). C. aurita sp. n. has an East African distribution, while the rest of

the genus has a distribution characteristic of many West African Tettigoniidae, extending from Sierra Leone and Guinea to Angola, Congo and Uganda.

KEY TO THE SPECIES

The characters employed in the key are chosen partly for convenience in use, and are not always those on which the most weight is placed in the diagnoses of the species. Hence, the key does not provide a complete diagnosis of each species, this being a function of the descrip- tions. Every specimen, therefore, needs to be compared with the description indicated by the key before the identification can be considered reliable.

C. ramulosa sp. n. is very closely related to C. nanus sp. n., from which it can be readily distinguished by the many-branched MA , pectinate Rs and more conspicuous pattern of the archedictyon of the fore wings, and by the coloration of the pronotal lobes. C. nanus sp. n. and C. ramulosa sp. n. may possibly be shown by the evidence of further material to be geographic variants of the same species. However, in the absence of unequivocal evidence in this direction at the present, and since the two forms are clearly delimited in the available material, I prefer to treat them here as separate species rather than give them subspecific status.

C. ramulosa sp. n. is known only from eastern Congo (Kinshasa).

C. capreola Karsch has a very strong affinity with C. naevia sp. n., from which it is most reliably distinguished by the coloration of the external spinules of the hind femora. It also differs from that species in the coloration of the pronotal lobes, the shape of the male cerci viewed in their plane of principal curvature, and the number and distribution of teeth in the stridulatory file (see Text-fig, i). The differences between the two species in the gonangulum of the ovipositor are not always as clear as in the specimens figured here, being of a similar magnitude to intraspecific variation and variation in distortion through drying.

The known range of C. capreola Karsch extends across West and Central Africa from western Liberia to Uganda and northern Angola.

This species is very similar to C. capreola Karsch, from which, however, it shows a consistent distinction in the coloration of the external spinules of the hind femora, and also in the number and distribution of teeth in the stridulatory file (see Text- fig, i). Other real though perhaps less clear-cut differences exist in the coloration of the pronotal lobes and the shape of the male cerci. The infragonangulum of the ovipositor tends to be more inflated than in C. capreola Karsch, but this is a rather subtle distinction that may be masked by the distortion of the basal sclerites due to drying. Although there is an overlap of the ranges of all the dimensions measured, C. naevia sp. n. is appreciably larger on average than C. capreola Karsch.

C. naevia sp. n. is distributed in West Africa from Sierra Leone to Ghana. Holotype^. LIBERIA : Marshall Territory, 30. vii. 1955 (Fox) (ANS Philadelphia).

C. apicalis (Bolivar) is very similar to C. neutralipennis Karsch. The males of the two species are distinguishable clearly only by the form of the apex of the cerci. Female specimens may be very difficult to distinguish and it is sometimes necessary to place some reliance on their association with identifiable males. See also dis- cussions under C. neutralipennis Karsch and C. afra (Karsch).

The known range of C. apicalis (Bolivar) extends across tropical Africa from Sierra Leone to Uganda.

The identity of the holotype is not at all plain. It resembles C. apicalis (Bolivar) in size and general appearance, but the form of the basal mechanism of the ovi- positor is not distinguishable from that of C. neutralipennis Karsch, and in the coloration of the fore wing base it differs slightly from either of these species. C. afra (Karsch) is almost certainly a synonym of either C. apicalis (Bolivar) or C. neutralipennis Karsch (in fact, the last two may also prove to be one species — see discussion under C. neutralipennis Karsch) ; however, without males that could be confidently associated with the holotype, I have been unable to resolve the problem here. The four other females that I have included under this species agree with the holotype in the form of the ovipositor and the coloration of the fore wings and hind femora, but are considerably smaller.

C. afra (Karsch) is known only from Nigeria.

This species can be distinguished with certainty from C. apicalis (Bolivar) only by the shape of the cereal apex in the male. Identification of female specimens may be impossible, for while the ovipositors of the two species may have quite different superficial appearances, their structure is essentially similar and many specimens appear intermediate when compared with the figures given here. The differences may be due to the effects of very slight differences in the relative growth rates of the basal sclerites on the manner of distortion of the integument during development. Such small differences in relative growth rates need not of course be between species, and are quite likely to be intraspecific. They are also likely to be related to the absolute dimensions of the adult insect, and since C. apicalis (Bolivar) is larger on average than C. neutralipennis Karsch, a size-related feature could falsely appear to be a specific character. There are some grounds for believing that this is probably the case here, and since the females have been segregated entirely on the appearance of the basal mechanism of the ovipositor, the division into ' species ' may be in effect no more than a separation of the larger specimens from the smaller, and as such does not necessarily correspond in any way to the division between the two male forms, which is based on a discontinuity in the form of the cerci. In both sexes the two species are so similar in all other features that the possibility must be borne in mind that they and C. afra (Karsch) may all belong to one species, dimorphic in the male sex over part of its range, and highly variable in size. At present, however, there is not sufficient evidence to justify synonymizing the three names.

C. neutralipennis Karsch is distributed in West Africa from Sierra Leone to Cameroon.

C. ambigua sp. n. is similar in many respects to C. neutralipennis Karsch and to C. pundulata (Karsch). There is no possibility of confusion with the latter species which has a unique coloration of the fore wings. It may be distinguished from C. neutralipennis Karsch by the ovipositor, the coloration of the hind legs, and the pronotal stria when this is present. The ovipositor is rather similar to that of C. nigrospinosa (Brunner) but may be distinguished easily enough. The locality may be helpful in identifying difficult specimens (e.g. badly discoloured males), since the range of the species does not appear to overlap those of its most easily confused relatives.

This is one of the most clearly defined species in the genus, being conspicuously unique in the coloration of the fore wings, and the form of the male cerci, stridulatory file and ovipositor valves. The basal mechanism of the ovipositor is very similar to that of C. guttatipes Karsch, differing from this chiefly in the deeper concavity of its first gonocoxa. It is best distinguished from this species by the more slender ovipositor, the depressed cerci of the male, and the type of basal mark of the fore wings. The number and depth of colour of the dark cells of the fore wings are very variable, and the isolated spots characteristic of the species are not always easily discerned ; a piece of white paper held behind the wing is sometimes helpful in detecting these in badly faded specimens.

The known range of C. punctulata (Karsch) extends across tropical Africa from Sierra Leone to Uganda.

The ovipositor of this species is extremely similar to that of C. punctulata (Karsch), differing chiefly in its more strongly concave first gonocoxa and much less slender valves. Male specimens could be confused with C. occidentalis sp. n. and may best be distinguished by their shorter, more strongly sinuose cerci. Two male specimens from Congo (Kinshasa) and one female from Cameroon have two con- spicuous fuscous bands, one apical, in the distal half of the hind femora. The males are set apart from the rest of the material examined also by the high number of teeth (79 and 82) in the stridulatory file. These two males are linked tenuously to the other 27 examined, among which the highest tooth number recorded was 55, by one specimen with 63 stridulatory teeth (see Text-fig, i), and with no trace of dark bands on the hind femora. None of these unusual individuals differs sufficiently from the other material in any other characters to be considered specifically distinct, and the variation seems to have no broad geographic significance, so no formal nomenclatural recognition is indicated.

C. guttatipes Karsch appears to be sparsely distributed in Central Africa from eastern Nigeria to Uganda, but is also recorded here from two localities in southern Guinea.

C. occidentalis sp. n. is nearest morphologically to C. guttatipes Karsch with which the males could sometimes be confused ; the cerci, however, are usually much longer and rather less sinuose than in the latter species. The females are easily dis- tinguished by the form of the basal mechanism of the ovipositor, which is quite unlike that of any other species.

This species is known only from Liberia and Ivory Coast.

The form of the lateral lobes of the pronotum, the absence of black markings from the pronotum and from the base of the fore wings, and the absence of tympanic auricles, taken in combination distinguish this species from its congeners. The female is additionally characterized by the distinctive, though somewhat variable, form of the basal sclerites of the ovipositor, and its toothed dorsal valves.

This species presents a morphological link between the typical species of the genus and the East African species with its tympanic auricles, its affinity with the latter species being manifest in the toothed ovipositor, the form of the basal sclerites and the shape of the pronotal lobes.

When the material from north of the Congo River is compared with that from the south side, differences in dimensions, and subtle differences in the ovipositors, are apparent. In the southern group the apical teeth of the ovipositor are bigger, the appearance of the basal sclerites is somewhat different and the length of the fore wings relative to that of the hind femora is less (see Text-fig. 95). It would not be

unreasonable to suppose that the Congo River might sufficiently restrict gene-flow between the northern and southern populations for stable subspecific distinctness of the two groups to be maintained. Carcasson (1964) stated : ' Very often the ranges of two vicariants will be separated by a partial geographic barrier which may not have been the cause of the original disjunction, but may help to stabilize their respective ranges . . . The Congo River and the Rift Valleys of East Africa are also important dividing lines, though not necessarily effective barriers '. In the present case, however, I consider there is not sufficient justification for introducing subspecific names into nomenclature, and any conclusions based on the morphological discontinuity between the groups must have regard to the small number of specimens examined.

C. serrifera sp. n. is known only from the lowland forest zone of Central Africa (Text-fig. 94).

C. aurita sp. n. is very clearly distinct from the rest of the genus, having a rudimen- tary to quite well developed auricle on the internal side of the tympanic organ. The distribution has no intersection with that of any other species. C. serrifera sp. n. provides a geographical and morphological bridge from this to the typical species, having the unusual form of the pronotal lobe in common with C. aurita sp. n., an ovipositor in many respects intermediate, and a tympanic organ of the typical form. In C. aurita sp. n. the teeth of the ovipositor are larger and more regular in shape than in C. serrifera sp. n., and the form of the basal mechanism, though similar, can be distinguished easily enough ; however, the best distinguishing feature of specimens with poorly developed tympanic auricles is the number of teeth in the stridulatory file. The variations in coloration, size, and form of ovi- positor and tympanic organ have no apparent geographic correlations.

C. aurita sp. n. is known only from East Africa, ranging from southern Kenya to southern Rhodesia and Mozambique (Text-fig. 4).

This species differs from the rest of the genus in so many characters, the most striking of which are the form of the eyes, cercus and fore wings, that one may suspect that the discovery of the female could make the erection of a new genus desirable for it. As it is, without the evidence of the female, and more particularly of the structure of the ovipositor, the species rests not too uncomfortably in Catoptro- pteryx Karsch, and it is most conveniently left here for the time being. There is some geographic variation in the pronotal coloration and the form of the cerci and eyes. At the western and eastern edges of the range the pronotal stria is absent, and in specimens from Cameroon and Fernando Poo the eyes are narrower (Text- figs. 5 and 8) and the cerci less strongly curved (Text-fig. 79).

Catoptropteryx extensipes Karsch has a West African distribution, ranging from Sierra Leone to Cameroon and Fernando Poo.

SYNOPSIS

A list of the type-specimens of Odonata in the British Museum (Natural History), belonging to the eleven above-mentioned families has been prepared. Four hundred and two taxa are dealt with and lectotypes are designated for one hundred and thirteen of these taxa.

This list completes those published in 1968, Bull. Brit. Mus. nat. Hist. (Ent.) 22 (7) : 277-305, and 1969, op. cit. 23 (7) : 287-314. The present list was completed in May 1969.

paulina Drury (Libellula), 1773 : pi. 40, fig. 4.

Calvert (1932 : 4) was unable to trace the type of this species. McLachlan's collection, however, contained a single example, lacking head and abdomen, without locality label but bearing one of his type labels and labelled by him 'Palaemnema paulina Drury'. The apical brown wing markings are rather more extensive than in Drury's figure, extending basally by about the length of the pterostigma. If it is Drury's specimen, I suspect that it has been re-pinned. I have no information as to how this example came into McLachlan's possession, but see Kimmins (1969 : 306) under titia. Selys (1886 : 146) states 'Patrie: Mexique. Honduras d'apres Drury; coll. Selys, Mac-Lachlan.' There is no indication that McLachlan's specimen was Drury's type, and I am of the opinion that it may have been labelled Type by McLachlan in error. I am retaining it in our type-collection in case information should come to light as to its history.

This taxon has a strange history. Strict application of priority of publication would make it Coeliccia fraseri Fraser, since a description of it appeared in Fraser's Indian Dragon- flies, published on 15 Feb. 1932, with reference to Laidlaw, 1931. Laidlaw's paper was delayed and did not appear until March 1932. Fraser states 'type in B.M.' and Laidlaw 'At present in my collection ; the types will be deposited in the British Museum.'

The BMNH has a specimen, presented by Fraser in 1937, with all the labels in Fraser's writing, which he had marked as type ; the year of capture does not agree with the description, and I am considering it at present as a possible syntype. I understand that part of Laidlaw's collection was acquired by the late John Cowley, and it is therefore possible that additional syntypes or even the actual type may be amongst his papered material (now in BMNH). I propose therefore to defer any decision on the type of this taxon until it has been possible to examine the Cowley Collection in detail.

Lieftinck quotes the number as 89, but by comparison with the allotype $, which has the number on the right hand end of the label, I think that the type should be 68.

[lieftincki Laidlaw (Coelicci a), 1932 : 32-33. In May 1931, prior to publication, a $ and $ were presented to BMNH by Laidlaw, who stated in his letter (3^.1931) 'C. lieftincki is at present a MSS name.' It was naturally assumed that these were the types and they have been so marked since that date. In the preparation of these type-lists, it was noticed that collecting dates differed from those given in the description, and that the types were stated to be in the Lieftinck Collection. Dr Lieftinck has informed me that he does have the types, and the BMNH examples are therefore merely additional material, not of the type-series. The male is in very poor condition, lacking most of abdomen.]

The (J lectotype has had the 7-10 segments of the abdomen re-attached with glue at some time, probably by McLachlan.

We have in our collection an example labelled by Asahina 'Cercion sieboldii Selys = quadrigerum Selys, det. Asahina, !953' so presumably this is a variable character.

I do not regard Calvert's statement (1901 : 65) concerning the incomplete example from McLachlan's collection (labelled 'Type') and studied by Calvert, as a designation of lectotype, since McLachlan so labelled all the type-series in his collection. I do not know of any later type-designation and have therefore designated the above complete example as Lectotype.

PSEUDOLESTIDAE

inopinata McLachlan (Thaumatoneura), 1897 : 131. Holotype <$ (incomplete). [No locality data] / Thaumatoneura inopinata McL. (Type).

The specimen was purchased by McLachlan, without locality data and with abdominal segments 5-10 lacking.

The lectotype lacks segments 7-10 of abdomen. The name J. T. Thomasson on the label is that of the donor; the material was collected by J. Whitehead. There is a seventh ex- ample, by the same collector, in the BMNH from the Crowley Bequest. This is complete, but cannot be included in the type-series. In view of this additional example, I have labelled the paralectotypes.

In describing this species, Calvert states 'Mr F. D. Godman has recently acquired for the Biologia Centrali- Americana six males of this genus, taken at Carrillo, Costa Rica, by Mr F. C. Underwood. Four are T. inopinata McLachlan, two are new.' The specimen in our collec- tion is part of the BCA collection, which was acquired by the BMNH in 191 1. It was labelled COTYPE by Calvert, but one would assume that Godman would have had the type in the BCA collection. I do not know of any earlier selection of type for this species and I have therefore designated the BMNH example as Lectotype.

I consider that Montgomery, by his statement 'Type: 3- Intaj, Ecuador .... In Br. Mus., ex coll. McLachlan' in effect designated the BM(NH) example (which then carried a holotype label) as the Lectotype.

SYNOPSIS

A preliminary survey is made of the genera and species of Asilidae known to occur within the geographical area of the Congo Basin. Keys are given to tribes and genera : wherever possible, keys are given to all the African species of the genus (S. of the Sahara), but in some genera at this stage it is possible only to give keys to the species known to occur in the Congo Basin. A few big genera — notably Ommatius and Neolaparus — are so poorly known that keys are useless until a generic revision has been undertaken. Three new genera and 39 new species are described.

INTRODUCTION

THE present paper originated in an invitation to examine and report upon the Asilidae taken in the Garamba National Park, in the extreme north-east corner of the Congo Basin. At the time I had on loan a good deal of material from the Muse"e Royal de 1'Afrique Central, in Tervuren, and from the Institut Royal des Sciences Naturelles de Belgique, and collections from Urundi and from Kasai made by my friend Monsieur Frans Francois. All the authorities concerned kindly agreed that I should write a combined report on their material, which should be published in the series of volumes of the Exploration du Pare National de la Garamba : Mission H. De Saeger.

Unfortunately changed circumstances made it impossible for the paper to appear in this form, and the Editors of the Bulletin of the British Museum (Natural History) generously agreed to accept it for publication in their series. The collections of the British Museum (Natural History) are rich in Asilidae from most parts of Africa except the Congo Basin, and the present collections fill a noticeable gap, in the centre of the African continent. It is hoped, therefore, that this preliminary

210 H. OLDROYD

review will give some indication of what genera and species of Asilidae occur within the Congo Basin, and form convenient links with other papers on genera and species from other parts of Africa, south of the Sahara, which will be necessary before the Asilidae in the British Museum (Natural History) can be adequately identified.

The expression ' Congo Basin ' is used loosely to cover the geographical area drained by the Congo River. Biologically the fauna of the north-eastern corner (where the Garamba National Park is situated) has links with that of Uganda and Kenya ; species of the Congo Basin proper also extend into the rain forest areas of the Cameroons and southern Nigeria ; while the fauna of the Katanga uplands is linked with the Rhodesia highlands rather than with the lowland rain forest.

ASILIDAE

Asilidae (Robber Flies) are attractive to the collector of insects because they are usually easily seen, and because they behave in interesting ways. All known members of the family are predatory, adults of both sexes feeding by sucking the body-fluids of other insects, and occasionally of spiders. Most of them capture their prey in flight, grasping it with the fore legs, piercing it with the proboscis, and sucking it dry. They feed either in continued flight, or after first alighting with their prey.

That this habit is well-established in the evolution of the Asilidae is shown by the degree to which their structure is adapted to an aerial, predatory life. The head, in particular, is highly functional in its structure. All Asilidae have the eyes separated, though sometimes closely approximated at one point. A characteristic of the family, by which Asilidae may be distinguished from, say, Therevidae, is the way in which the vertex of the head is sunk beneath the level of the eyes. Another way of expressing this is to say that the eyes are raised above the level of the head, and this is a more significant description, indicating that the eyes are specially developed in this family.

The eyes are of such a shape that a considerable area of each eye faces forwards, and these areas are equipped with facets larger than the rest (Text-figs 56, 57, 60). The appearance is such as to suggest a special acuity of vision in a forward direction, correlated with the need to identify prey, and to catch it in the air. Compared with many other Diptera, the eyes of Asilidae are generally flattened in front, thus

ASILIDAE OF THE CONGO BASIN 211

exposing a greater proportion of the facets to the front and relatively few to the side, though these lateral facets are strongly curved, and so command a wide field of view.

These characteristics of the eyes are most exaggerated in the tribe Xenomyzini, where the effect of large, flattened eyes and tiny frons and face is usually described as being ' goggle-eyed '.

The legs of Asilidae are developed for the pursuit of prey. In general, they are stout and strong, in contrast to the fragile legs of such aerial insects as Bombyliidae. Nearly always they are covered with hairs and strong bristles, which obviously fulfil a practical function in holding the struggling prey, and preventing it from injuring its captor ; the characteristic ' moustache ' of the Asilidae, a mass of bristles just above the base of the proboscis, similarly keeps the prey away from the eyes and antennae of the robber fly.

In a few genera the legs have acquired additional devices for grasping prey. The most advanced example is in the genus Gonioscelis, where the fore femur is expanded basally and its ventral surface is heavily armed with spines and bristles, which meet the tibia to form a crab-like prehensile organ (Text-fig. 49). In Hoplopheromems the mid-femur and tibia are equipped with long, spiny bristles. Many genera have the hind femur swollen and strong, with its curved tibia closing firmly on to it. This development has occurred, obviously independently, in genera of all tribes, sometimes, as in Hoplistomerus, with the spines carried on warts or other processes of the femur.

One of the most enigmatic of such devices is the fore tibial spur of certain genera of Saropogonini, including Saropogon itself. This formed the basis of Hermann's group Acanthocnemini : a convenient device for quick identification, but an unsatisfactory basis for a classification, since we still cannot say whether this tibial spur is a practical device — thus showing similarity of habit, or of prey — or a functionless relict from some ancestor, and thus an indicator of affinity. Some species of Microstylum (Mimoscolia) have a similar spur and terminal process on the mid- tibia (Text-fig. 39).

The wings of Asilidae are of primary importance in the taxonomy of the family, though the range of venational pattern is comparatively restricted. A discal cell is always present, and an almost full set of longitudinal veins : Sc, R\, RZ+Z, ^4+5, MI, MZ, MZ, M4, Cui, i A. Variations in venational pattern arise from the meeting of adjacent veins before they reach the wing-margin, and thus the closure of certain cells, of which the most important is the marginal cell, lying between the veins R\ and RZ+S (Text-fig. 69).

The marginal cell is closed, with a short terminal stalk, in Asilini, Ommatiini, Atomosiini, and most Laphriini ; it is open, with veins RI and RZ+S reaching the wing-margin separately, in Leptogasterini, Saropogonini, Stichopogonini and Xenomyzini. In certain genera related to Laphystia this cell is normally open, though vein R2+3 has a characteristic retrograde curve. These genera comprise Hermann's group Prytaniinae and Hull's tribe Laphystiini, transitional between the old subfamilies of Laphriinae and Dasypogoninae. In most respects they are most closely related to Laphriini, and are here treated as belonging to that tribe.

212 H. OLDROYD

It is generally assumed that open cells are a more primitive condition, and closure of cells is a specialization ; though of course this specialization has occurred in- dependently in many different lines of evolution. The most generalized venation occurs in the Leptogasterini, where often all the cells are open, including the anal cell. The last is particularly variable, being sometimes divergently open, almost as in some Nematocera, but sometimes closed far from the wing-margin. Leptogasterini have lost the alula, and the shape of the wing and of individual forks and cells show clearly that being generalized cannot necessarily be equated with being primitive.

Leaving aside the Leptogasterini, which are a peripheral group, whether primitive or advanced, the central group of the family is the Saropogonini with Stichopogonini and Xenomyzini as specialized offshoots. Saropogonini include a diversity of genera, all of which have an open marginal cell, even though other venational specializations occur, e.g. in Microstylum.

The generally robust structure of Laphriini extends to the wings, where additional strength is often provided by the closure of both the first and fourth posterior cells (Text-figs 18-20). These must give considerable rigidity along the posterior area of the wing. On the other hand the actual wing margin, which in Asilidae is normally sclerotized into an ' ambient vein ', is membranous in a number of genera, especially in Laphystia and related genera.

Among Asilini the conspicuous peculiarity lies in the genera Promachus, Alcimus, Philodicus and Apoclea, where an additional vein unites the fork of R^+5 with the stem of Rz+3, producing three submarginal cells. Since Asilini are clearly an advanced tribe, which at specific level show signs of recent evolution, it would be reasonable to visualize this additional vein as a new structure, perhaps giving additional rigidity to the radial field of the wing. However, many Brachycera in different families have a stump vein on the radial fork, and sometimes a complete cross-vein : for example, some Bombyliidae, including the entire tribe Exoprosopini.

There has therefore been a temptation to look upon three submarginal cells as a primitive condition in Brachycera, from which the more usual two submarginal cells are derived by reduction. Shannon and Bromley (1924) regarded the Promachus-group of genera as evidence that the proper numbering of the branches of the radial sector should be : RI, RZ, ^3+4, ^5. In this way Shannon & Bromley accepted it as axiomatic that the additional vein in these genera is a true vein, one of the ancestral complement.

In fact, supernumerary veins often occur in Brachycera. In Nemestrinidae they are a regular feature of certain genera. In Syrphidae the ' spurious vein ' is a family characteristic. Among Asilidae it is quite common to find supernumerary cross-veins, sometimes only in one wing. The small anterior cross-vein (r-m) is often duplicated. There is evidence that such veins appear during the pupal period, and are the result of sclerotization of a fold. On this interpretation it is suggested that the stump vein from the radial fork, when this is present, and even the complete vein in Promachus and its allied, are no more than this, and give no indication of phylogeny.

The thorax and abdomen of Asilidae show no remarkable features. The abdomen varies from slender and elongate in Leptogasterini, most Asilini and many other

ASILIDAE OF THE CONGO BASIN 213

genera, to the extremely squat abdomen of genera such as Sisyrnodytes, in which the abdomen is short, broad, flattened, and bee-like in form.

With few exceptions, the genitalia of both sexes are exposed, and readily examined for purposes of classification. Female terminalia may be simple, or they may take the form of an ovipositor. Although an ovipositor may appear highly characteristic it is an adaptive character, suited to the requirements of egg-laying. The larvae of Asilidae live either in soil or in wood, but the eggs are laid in a variety of special sites. They may be simply dropped on to the ground, in which case the ovipositor is of very simple, lamellate structure. Many eggs are concealed in flowers, leaf-axils, or even inside a slit cut into the tissue of a plant : it seems that the object is conceal- ment and protection of the egg, and possibly of the first instar larva. Many of the more striking ovipositors, which are most frequent in the advanced tribe Asilini, are adapted to the circumstances of oviposition. The manner of oviposition may be quite different in related genera, or even within a single genus, and so ovipositors are unreliable indicators of relationships.

Male genitalia present a complicated problem. They are constructed mainly from the ninth segment. The ninth tergite, or epandrium, is sometimes entire, sometimes split into the superior forceps. From the ninth sternite arises a pair of inferior forceps (gonopods) which often appear double because each bears on its inner surface an accessory lobe, the clasper. Within the two claspers appear the aedeagus and its two parameres. The basic pattern is thus that of a trifid median structure, flanked by three pairs of lobes, and topped (dorsally) by a median pad formed from the paired anal lamellae (proctiger).

The variations upon this basic structure are extensive, and are made more confusing by partial or complete inversion. Thus in Laphriini the typical genital structure is boat-shaped, the apparent hull of the boat consisting of the undivided ninth tergite (epandrium), which has become inverted and appears to house the other (ventral) appendages (Text-figs 3-36).

The problem of rotation of male genitalia in Diptera, leading to inversion, has received undue prominence in textbooks, more especially in regard to muscoid flies. Rotation may be a source of confusion in comparative morphology, but — at least in Asilidae — it is usually possible to distinguish between the true dorsal aspect, with the lamellae, and the true ventral aspect, with the gonopods and claspers. As an indication of relationships, rotation is an unsafe guide. In many genera rotation occurs during mating : i.e. the genitalia of the two sexes are engaged, and then the male changes position, twisting the genitalia in the process. This rotation may be partial or total, depending upon the mating attitudes, and may or may not persist during later life, or after death. Consequently no attention should be paid to rotation per se, beyond ensuring that the correct orientation of the parts is under- stood before they are compared with others.

The specific identification of Asilidae is much more difficult than is generally thought, and possibly for this reason this attractive family has not been as exten- sively studied as, say Syrphidae. No large scale revision of African Asilidae has ever appeared, and in every genus the student is faced with a dilemma : if few species are known, then material is scarce, and comparison difficult ; if material is

214 H. OLDROYD

abundant, as in Ommatius and Neolapams, the variation is so great that specific identification is not possible until the whole genus has been revised.

Substantial progress in knowledge of African Asilidae will come only from com- plete revisions of successive genera.

THE ASILIDAE OF THE CONGO BASIN

The collections of the British Museum (Natural History) include much material from Africa south of the Sahara, but for historical reasons little of this comes from the area of the Congo Basin. The writing of the present paper seemed to provide an opportunity to review the Asilidae of this larger and important natural region of central Africa, which would be complementary to later studies that it was hoped to make of Asilidae from the rest of the Ethiopian Region.

Unfortunately as the work progressed it became evident that a number of genera were insufficiently known for a definitive review to be possible. The outstanding example is the genus Neolaparus, flies of deceptively simple appearance which so far have resisted all attempts at a classification. Only a thorough study of all the African species, with an attempt to find new taxonomic characters, will make it possible to rationalize this genus. Ommatius is more tractable, but there is an abundance of species, many of which are clearly of wide distribution. These and several other genera must be revised for the entire region before it will be possible to deal adequately with any faunistic survey.

The material described in the present paper, therefore, consists of the collections of the Mission H. De Saeger from the Pare National Du Garamba, together with such other material as could be handled satisfactorily at the same time. Whenever possible I have given a key to species, from this collection, or from the Congo Basin, and in some genera a key to all the known species from the Ethiopian Region.

One fact that clearly emerges from this study is that there is no fauna of Asilidae that is characteristic of the Congo Basin, or even of the equatorial forest belt as a whole. The distribution of Asilidae resembles that of Tabanidae : both families seem to flourish best in savanna country, with an open, mixed vegetation, which provides a multiplicity of habitats.

There are interesting parallels between the tribe Laphriini of the Asilidae and the genus Chrysops of the Tabanidae. Chrysops spp. are known as ' deer flies ' in North America because their typical habitat is the open woodland in which deer abound, and Laphriini, with their wood-living larvae, are characteristic of this habitat. Chrysops has invaded the high forest by way of the tree-canopy, coming down to ground level where the canopy is broken by rivers, by clearings, or by the out- cropping of rocky or mountainous areas which bring ground level up to the canopy of the surrounding forest. It would be interesting to discover whether the high canopy of the Congo Basin also supports a large population of Laphriini, which fly among the tree-tops and prey upon the Hymenoptera and other insects feeding on the flowers of the forest trees.

The Pare National du Garamba is not situated in high forest, and has not much open woodland. It is mostly park savanna, i.e. predominantly grassland with scattered trees (Exploration du Pare National du Garamba ; Afdelung Introduction,

ASILIDAE OF THE CONGO BASIN 215

p. 101 ; pis. III-XII). It is noteworthy that Laphriini are poorly represented within the confines of the Pare, though they are numerous among collections from elsewhere in the Congo Basin.

The Asilidae of the Pare National du Garamba are mainly Saropogonini, Stichopogonini, Xenomyzini and Asilini, and belong to genera which have a wide distribution throughout the savanna areas of Africa. It is these genera (e.g. Neolaparus, Ommatius) that cannot be comprehensively treated in the present paper, because the Garamba fauna is a small and unrepresentative sample of a very ex- tensive and difficult range of species.

Tribe LEPTOGASTERINI

Members of this tribe have a characteristic habitus, which sets them apart from nearly all other Asilidae. The abdomen is long and slender, usually slightly clubbed apically. The wings are generally narrow, with the anal lobe and alula evanescent, and with a simplicity of venation in which even the anal cell is often wide open. The legs are slender and elongate, especially the hind pair, of which the femora and tibiae may be clavate. Pulvilli are always absent, and the empodium may be absent or greatly reduced. The metanotum and postmetacoxal area are flattened obliquely, in such a way that the coxae are pushed forwards, and the base of the abdomen raised, contributing to what has been called the ' agrionid ' appearance of these flies. The thorax of many Leptogasterini is further distorted by having the dorsum compressed into a hump, arid by the development of a pair of processes on the mesonotum which overlap the pronotum ; in the genus Euscelidia a process of the pronotum lies between them.

1 For a fuller account of tribal classification, and a bibliography see Oldroyd (1963).

216 H. OLDROYD

To a great extent these features of Leptogasterini are clearly adaptive. The tarsi, for instance, are adapted for curling securely round a grass stem, in which process they are actively assisted by the long, curved claws, and by the loss of pulvilli.

Dipterists who have specially studied Leptogasterini have been led to emphasize the differences between these and all other Asilidae. Janssens (1954 : 114) stated an extreme view : ' Je considere . . . qu'il y avait lieu peut-etre d'instituer pour Leptogaster et quelques voisins une famille qui formera avec les Asilidae une super- familie ASILOIDEA '. Martin (1968) developed this view at some length, but Oldroyd (1969) examined Martin's argument in detail, and endorsed the view of Hull (1962 : 296) that : ' All these characters are collectively found in Lepto- gasterinae, but are singly shared with other asilids '.

The subdivision of Leptogasterini into genera is also unexpectedly difficult. The key given by Oldroyd (1963 : 8) is unsatisfactory in some particulars, and fails to locate generically any species with the following combination of characters : occiput with fine hairs only, without bristles ; no bifid pronotal process ; and no swollen or plumate hind legs. Such specimens might be regarded either as Lepto- gaster without occipital bristles or as Euscelidia without the pronotal process ; sometimes the general impression is of the former, sometimes of the latter.

In the present paper the genera are interpreted as in Janssens' papers, and all species which lack the pronotal process, and have the anal cell widely open, are classed as Leptogaster, whether or not they have strong occipital bristles.

Very few species of Leptogaster had been recorded from the Congo Basin until Janssens described twenty-five species in a series of papers (1952-57). Many of these are known from unique specimens, and only a study of much more extensive

material will make it possible to indicate the extent of intraspecific variation, or the distribution of species within the area. In the meantime the following key, compiled from the published descriptions, is offered as a guide to provisional identification. In addition to Janssens' species there are L. ludens Curran (1927 : i) — a single female from Banana, at the Congo mouth — L. bicingulata Bezzi (1905 : 279) described from Eritrea and recorded by Janssens from Kitega ; and L. picti- pennis Loew (1857 : 353) described from S. Africa, and also recorded by Janssens from Bururi.

EUSCELIDIA Westwood Euscelidia Westwood, 1849 : 232. Type-species : Euscelidia rapax Westwood, monotypic.

220 H. OLDROYD

Species of Euscelidia are usually recognizable by their general appearance, as robust and shining Leptogasterines. The type-species and a few others have hairy hind legs, which could lead to confusion with Lasiocnemus, but the existence of a vertical process of the pronotum projecting between the two processes of the mesonotum is diagnostic.

About eight or nine species of Euscelidia have been recorded from the Congo Basin, most of them described in various papers by Janssens. The differences in colour and pattern are more subtle than in Leptogaster, and it is not practicable to attempt a key compiled from descriptions. Only a detailed study of species both in the Congo Basin and outside it, with comparisons of genitalia, will make such a key possible. Meanwhile species must be named by direct comparison with Janssen's descriptions and figures.

The collection from the Garamba National Park contained two of Janssens species and two others that are clearly new.

Euscelidia moyoensis sp. n.

(Text-fig. 2)

A species with shining black thorax, and legs extensively marked in black, distin- guished from the other species known to me by the distinct black band at the extreme tip of the hind femora. From E. lucida Oldroyd it differs in the much less evident pattern of tomentum on the thorax, the more prominent silky hairs of the anterior sternopleuron, and the more abundant pale hairs of the moustache. It also has close affinities with E. datis (Walk.) from Sierra Leone, but cannot be compared in great detail because the unique type of the latter is too badly damaged : the fore and middle legs of moyoensis seem to be much more heavily infuscated.

cj Head. Frons and face with golden tomentum ; moustache a row of 15-20 white bristles on mouth-margin : no other facial or frontal hairs. Antennae (broken), palpi and proboscis black, with black hairs. Occiput with golden tomentum and fine yellow hairs.

Thorax. Mesonotum mostly shining black, with yellow tomentum only at extreme sides, and particularly anteriorly, and on humeral slopes ; long, golden hairs lie vertically, and long, yellowish white hairs arise from tomented areas ; rest of dorsum with short, black hairs. Scutellum covered with yellowish white tomentum, with erect, curved yellowish hairs on disc and on margin. Pronotum, including median lobe and twin lobes of mesonotum, covered with whitish tomentum, which also covers pleura. Mesopleuron, pteropleuron and anterior part of sternopleuron also with conspicuous tufts of long, snow-white hairs.

A bdomen in ground colour black, with yellow basally on third and fourth segments, the whole covered with whitish tomentum. Hairs mostly white, some black dorsally, longer laterally and on sternites, which are a little more yellow than tergites. Male genitalia (Text-fig. 2) black.

FIG. 2. Euscelidia moyoensis. Male genitalia.

ASILIDAE OF THE CONGO BASIN 223

Legs. A pattern of whitish yellow, deep honey-yellow, and black-brown. Black-brown covers extreme tips of fore and hind femora, most of mid femora except bases, a median ventral patch on inner face of each hind femur, anterior and posterior stripes on all tibiae, tips of all basitarsi, and all other tarsomeres. Hind femora with narrow, whitish yellow stem, deep yellow, elongate knob, and small, apical, black-brown band. All basitarsi conspicuously whitish yellow, except for extreme tip, which is black-brown. White bristles on tibiae, but tarsal bristles black.

DOLICHOSCIUS Janssens

Dolichoscius Janssens, 1953 : 2. Type-species : Dolichoscius francoisi Janssens, 1953, mono- typic.

Janssens has described two species of Dolichoscius in two separate papers. He clearly intended the type-species to be longipes, from the Upemba National Park, but unfortunately this paper (1954) did not appear until after the description of francoisi from Urundi, which becomes the type-species by monotypy.

Although Janssens (1952 : 6-10) records several species of Lasiocnemus from the Congo Basin, including such species as L. lugens Loew, which were originally des- cribed from distant parts of Africa, there were no species among the material from the Upemba National Park (Janssens, 1954), and none in the collections from Garamba.

For the sake of completeness in this review, therefore, I can only quote Janssens' key to the species recorded by him from the Congo Basin.

Tribe LAPHRIINI

More than one third of the species recorded in the present paper belong to the tribe Laphriini. Although this proportion is exaggerated by the fact that certain big genera of other tribes — notably Neolaparus and Ommatius — cannot at present be reported upon so fully, yet the abundance of Laphriini underlines the fact that these genera flourish among trees. Many, perhaps most of them, spend their larval life in the stumps of fallen logs, often in the burrows made by wood-boring beetles and carpenter-bees.

Most Laphriini are distinctive in appearance, broadly built, often with the ab- domen basally constricted ; wings strong, with stout veins, marginal and fifth posterior cells closed ; legs often stout, with inflated femora and curved tibiae ; and antennae stout, often clavate. The body surface is toughly sclerotized, and often punctate, giving the appearance of a strong, aggressive insect, with more than a superficial resemblance to a wasp or a bee.

Laphriini can usually be recognized by the combination of closed marginal cell and styliform antennae, in contrast to the aristiform antennae of the Asilini, and the open marginal cell of other tribes. It has been explained above (Introduction) that the present concept of Laphriini includes not only the tribes Andrenosomini and Ctenotini of Hull (1962), but also the more controversial ' Prytaniinae ' of Hermann, the tribe Laphystiini of Hull and others. On the other hand the Atomosiini, apparently only slightly separated by the small details of wing-venation, sustain this distinction on a world scale, though they are scarce in tropical Africa, and only one species is included in the present paper (see below).

LAPHRIA Meigen

Laphria Meigen, 1803 : 270. Type-species : Asilus gibbosus Linnaeus, by designation of Latreille, 1810.

Although nearly thirty species of Laphria have been recorded from the Ethiopian Region (Hull, 1962 : 323) this genus is not well represented in collections, either from the equatorial forest or from the savannah areas. The flies are among the most conspicuous of Asilidae, and easily attract the attention of collectors. To some extent their apparent scarcity may be a reflection of their feeding habits, which may take them in pursuit of wasps and bees high up in the trees.

The genus Laphria shares with Storthyngomerus and Dasyllina a characteristic type of proboscis, laterally flattened, with an acute edge both dorsally and ventrally, like a paper-knife. Presumably this has some relation to the nature of the prey, though its significance is not obvious : other Laphriine robber-flies, notably the genera Proagonistes and Hyperechia, will attack big Hymenoptera, but these have a proboscis of quite a different shape.

No species of Laphria is among the material that I have received from the Pare National du Garamba, but I have seen a number of species from other localities in and around the Congo Basin. It seemed useful, therefore, to give details of these, and to present a key that includes as many as possible of the species of Laphria recorded from the Ethiopian Region.

STORTHYNGOMERUS Hermann

Nusina Curran, 1927 : 7 ; Bromley, 1935 : 411. Type-species : Laphria dymes Walker, by original designation.

Each of these two genera was described in a brief note, indicating the type-species, but saying little about the limits of the genus, or of its affinities. The interpretation that I have put upon Storthyngomerus is that given by Lindner (1955).

The type-specimen of Laphria dymes Walker is in the BMNH, so that Nusina can be denned precisely. There can be no doubt that N. dymes is conspecific with Storthyngomerus tridentatus (Fabr.), and that only females have so far been assigned to these. On the other hand, Nusina aurea Bromley is known only from males, and it seems clear from material in the BMNH that most of these are also con- specific with dymes and tridentatus. Confusion is caused by the sexual dimorphism of the legs, the femora being all orange in the females and heavily darkened in the males. One male in the BMNH, with legs entirely orange like the females, has distinctive genitalia and is clearly specifically distinct.

The fact that the orange-legged females are conspecific with the dark-legged males and not with the orange-legged male is supported by the other characters mentioned in the key below.

Laphria testacea Macquart was transferred to the genus Storthyngomerus by Engel (1924), who did not give any reason for doing so, and it is difficult to understand why. The description of testacea Macquart agrees quite well with specimens of Trichardis testacea Hermann (q.v.), whereas the statement that the antennae are ' assez courtes ' does not suggest Storthyngomerus.

Lindner (1955) described Storthyngomerus minor, a very much smaller, black species, which seems incongruous with the much bigger typical species. Yet it shares the generic characters of Storthyngomerus which, besides the elongate antennae, include the absence of scutellar bristles and the presence of spiny tubercles beneath the hind femora, somewhat like those of Trichardis (q.v.).

(Text-figs 12, 14)

The solitary known male of this species is superficially very similar to males of S. tridentatus, but differs in having the legs entirely orange ; in S. tridentatus the females have orange legs, but the males have at least the middle and hind femora with broad black bands. The proboscis is distinctly shorter than in tridentatus, being only three-quarters as long as the height of the head instead of rather longer than this distance. In corroboration there are very clear differences in the male genitalia. (Text-figs 12, 14.)

o* Head. Facial knob prominent, occupying lower half of face and separated by a distinct hollow from the prominent tubercle on which the antennae stand. First antennal segment twice as long as second (third segment broken off). General colour of head black. Frons, vertex and upper occiput bare, shining black, with sparse black bristles. Face with yellowish grey tomentum except for a bare patch on facial knob. Hairs yellow, more scaly on middle of eye-margins. Stronger bristles of moustache black. Proboscis and palpi black : palpi with black hairs, base of proboscis with longer white hairs. Behind the eyes a broad strip of yellowish white tomentum, with black bristles on dorsal two-thirds, fine yellow hairs ventrally.

Thorax. Pronotum black with about eight strong black bristles. Mesonotum and scutellum black, uniformly covered with short, fine, black, bristly hairs and short, golden, silky hairs. Humeri with some longer black hairs, and prehumeral hollows with white tomentum ; one notopleural and one supra-alar black bristle ; no long marginal scutellars. Pleura black, covered with white tomentum except for mesopleuron, which has a large, bare, shining black area almost reaching to anterior margin, and so with the anterior white margin much less obvious than in S. tridentatus ; one black mesopleural bristle. Metapleural tuft before halteres black, bristles strong and dense.

Abdomen. Dorsum with reduced first segment and entire second segment black, with short black hairs ; second segment laterally with yellow hairs and a tuft of two or three strong orange bristles. Rest of abdomen, including genitalia, orange, with yellow or pale yellow hairs. Genitalia as in Text-fig. 12, distinct from those of <$ tridentatus in having lower forceps flattened and acutely tipped, with one long bristle and a short, subapical spine. No dorsal process curving round clasper. (Genitalia rotated through 180. °)

Legs. Trochanters black ; rest of legs entirely orange, with nearly all hairs and bristles yellow, except for a few on tarsi and a large patch of black dorsally on femora (S. tridentatus <$ has yellow hairs even over the black femoral patches).

Wings. Infuscation— both staining and microtrichiae — almost uniform all over, without clearer centres in basal, anal and axillary cells. Halteres orange.

Length of body 15 mm ; of wing 13 mm.

SMERYNGOLAPHRIA Hermann

Smeryngolaphria Hermann, 1912 : 226 ; Bromley, 1935 : 410 ; Hull, 1962 : 331. Type- species : Laphria melanura Wiedemann, 1828, by original designation.

Smeryngolaphria is a small and rather ill-defined genus from South and Central America. Bromley (1935) considered that it should be extended to include the Oriental species for which Hermann had erected the genera Anisosis and Orthogonis ; and the BMNH collection contains a number of red-and-black Laphriine species that were placed in Smeryngolaphria by Miss Ricardo.

Bromley also described Smeryngolaphria pallida from a single male from the eastern Congo. A second specimen from the same area is before me, and there is no doubt that it belongs to pallida Bromley. The generic assignment is less certain.

ASILIDAE OF THE CONGO BASIN 235

According to Hull (1962), and to specimens in the BMNH, it seems at least equally likely that it should be placed in the genus Cenochromyia Hermann (1912 : 115), another genus of yellow or reddish Laphriine flies from New Guinea and adjacent areas. It will not run to Smeryngolaphria in my key to African genera (Oldroyd, 1963 : n) because the metanotal slopes are hairy. In Hull's interpretation these slopes should be bare in Smeryngolaphria, though Bromley considered that they might be either hairy or bare. Bromley specifically mentions that they are hairy in his species pallida.

A clear decision about the genus of this fly cannot be made in isolation, and will have to await a more general study of the Laphriini.

LAXENECERA Macquart

Laxenecera Macquart, 1838 : 77 ; Hermann, 1919 : 337-358. Type-species : Laxenecera albibarbis Macquart (an Indian species), by designation of Hermann, 1919, loc. cit.

Acurana Walker, 1851 : 107. Type-species : Acurana sexfasciata Walker, monotypic.

Dyseris Loew, 1857 : 357 ; 1860 : 122. Type-species : Laxenecera andrenoides Macquart, by designation of Loew, 1860 : 122.

Laxenecera is most easily recognized by the fairly long, narrow third antennal segment, which bears a distinct fringe of hairs dorsally as well as ventrally. Macquart says that the name expresses the hairiness of the antennae. Unfortunately the antennae of Asilidae are prominent, and are easily destroyed in dried specimens, and then it is necessary to rely upon a combination of other characters. Moreover, dorsal hairs on this antennal segment also occur in some Hoplistomerus and Trichardis.

Laxenecera has the proboscis triangular in cross-section, the palpi very slightly clubbed at the tip, and usually the hind femora swollen with the hind tibiae corres- pondingly curved. Many of the species look like small bees.

There is one widespread, common, and variable species (albicincta Loew), and a number that are more locally distributed. There is considerable variation between individuals, and this is one of the most difficult genera to present in the form of a key to species. The male genitalia can be examined to some extent without dis- section, and show some differences between species, but I have not found these much use in identification. A confusing factor is the very great sexual dimorphism that is generally present : e.g. in albicincta the male is a slender black fly, with white hairs and no abdominal bands ; the female is a stout fly with rusty yellow hairs and bristles, and conspicuous bands on the abdomen. The leg-pattern is the most reliable way of associating males and females, but individual variation must be allowed for.

236 H. OLDROYD

The two species originally included by Macquart were from India, but as we know it today the genus is predominantly an African one. Loew erected the genus Dyseris for some of the African species as a result of an error in the numbering of a Plate in one of Macquart's works ; the error was pointed out by Hermann (1919).

Laxenecera abdominalis sp. n.

The male is distinguished from all other Laxenecera known to me by having the first three abdominal segments mainly or entirely covered with whitish hairs, while the rest of the abdomen has the hairs almost exclusively black.

o* Head. Clothed with golden hairs, except for a black tuft on each side of frons, close to antennae, and a black tuft in middle of occipital margin. First antennal segment with yellow hairs, other two with black hairs.

Thorax black. Ground colour of mesonotum and scutellum almost obscured by short, recumbent, whitish or yellowish hairs. Bristles longer, fine and hair-like, black on disc of mesonotum, whitish laterally and posteriorly, and on margin of scutellum. Pleura mostly obscured by brownish tomentum. Mesopleuron shining black, with a vertical posterior band of yellowish tomentum, and some black some yellow bristles.

Abdomen black, obscured by short, recumbent yellow hairs. On first segment and a broad posterior band on second and third, these are silky white, but on anterior half of second and third segments, and almost entirely on other segments, they are black. Venter black-brown with mainly yellowish hairs.

Legs mainly black, but tibiae and tarsi of fore and middle legs are extensively orange, with numerous yellow hairs and bristles. Hind femora black, with mainly black hairs, but with a few white ones dorso-apically, hind tibiae with dense and moderately long white hairs dorsally and ventrally ; hind tarsi with black hairs ventrally and a conspicuous fringe of dense silvery ones dorsally.

Laxenecera misema sp. n.

Closely allied to rufitarsis Bezzi (funditor Curran), from which it is distinguished in the male by the conspicuous fringes of the hind legs. In both sexes it is further distinguished by having the fore and middle tibiae orange, without a black stripe, and by having the occipital bristles all yellow, without a black tuft.

cJ Head with some black hairs on second and third segments, and on tips of palpi, otherwise all hairs of head yellow.

Short hairs golden, and closely recumbent, longer hairs and fine bristles mostly golden, but some black ones. Supra-alar and postalar bristles strong, yellowish, postalar callus a little reddish. Pleura, except for the usual bare mesopleural area, with brassy yellow tomentum and yellow hairs and bristles.

Abdomen black, each segment becoming dull reddish towards posterior margin. On hind margin of each is a triangular patch of whitish hairs at each corner, extending towards middle line ; adjacent to these is a band of yellow hairs, which cover whole of first and second tergites, but the others have black hairs over most of disc.

Legs of male with conspicuously swollen hind femora, and stout, bowed hind tibiae, with a brush of black hairs ventrally on apical half of femora and on full length of tibiae. Hind femora black with red apex and base ; tibiae red ; both femora and tibiae obscured by short black hairs. A few strong yellow bristles stand out among black hairs, especially on tibiae.

ASILIDAE OF THE CONGO BASIN 241

Laxenecera nigrocuprea Walker, 1855 : 572. Dyseris zonata Loew, 1857 : 358 Laxenecera stuhlmanni v. Roder, 1893 : 205. Laxenecera splendida Hermann, 1919 : 341.

The male and female of this species are normally so different that they might be mistaken for quite distinct species. Typically the male is black, with almost entirely black bristles, and no more than a trace of whitish bands laterally on the abdomen. The female is a more bulky insect, with obvious bands of whitish grey or yellowish grey on the abdomen, and with the hairs of the head, thorax and legs predominantly rusty yellowish. In particular the postalar tuft is rusty yellowish, and stands on a tawny callus.

The female has quite a close resemblance to the bee Megachile felina Gerst.

The variation in this species is most obvious in the male, where the presence of any white or yellowish hairs is more conspicuous than it is in the female. Hermann (1919) gave it as his opinion that stuhlmanni v. Roder was no more than a variety of albicincta, distinguished from the typical form by the somewhat differently coloured hairs, especially those of the legs. In Hermann's own variety splendida there is less difference between the sexes than in typical albicinda, and some males from the Congo Basin have taken on much of the superficial appearance of the females, especially in the rusty yellow postalar bristles, and in the pale moustache. Somewhat similar variation occurs in specimens from the Gold Coast collected by Dr John Bowden. These males seem to have genitalia indistinguishable from those of the typical form.

Laxenecera albicinda is common and widely distributed in eastern and southern Africa, from ETHIOPIA to NATAL and ZULULAND, and round to the mouth of the River Congo. Although it occurs round the fringes of the Congo Basin, and occasionally on the river itself, it is not properly a forest species.

NUSA Walker

Nusa Walker, 1851 : 105. Type-species : Nusa aequalis Walker, by designation of Hermann,

1912 : 239. Dasythrix Loew, 1851 : 21. Loew, 1860 : 124. Type-species : Laphria (Dasythrix) inornata

Loew, by original designation. Halictosoma Rondani, 1873 : 298. Type-species : Halictosoma puella Rondani, monotypic.

Hermann (1912) was misled by the original drawing of Nusa aequalis Walker into accepting this as an earlier name for Andrenosoma Rondani, but Ricardo (1927) after studying the type in the BMNH, rightly removed Nusa into synonymy with Dasythrix Loew, 1851, over which it was shown to have three months' priority.

Loew divided his genus Dasythrix into two sections, making inornata, a South American species, type of the first section, and infumata, a South African species, type of the second. Loew gave no distinctions between his two sections, and I have not seen the S. American inornata, which clearly must be the type of any restricted genus Dasythrix. Nusa aequalis Walker is from India, and is congeneric with the African species. Hence, if at a later date it should prove that Loew's two sections are not congeneric with each other, section i, type inornata, would retain the name Dasythrix, and section 2 would still be called Nusa.

Ricardo (1925 : 278) described 'Nusa africana <$, Hermann in litt., sp. n.', and stated that this species was congeneric with Andrenosoma boranica Corti from East

244 H- OLDROYD

Africa, accepting at that time Hermann's view of the synonymy between Nusa and Andrenosoma. Later (1927 : 206), when she realised the true identity of Nusa Walker, Miss Ricardo renamed her species Andrenosoma africana, but examina- tion of the series in the BMNH, including the types, shows that even this is in- correct. Nusa africana Ric. belongs to the genus Proagonistes , and is not congeneric with boranica Corti, which is a true Andrenosoma.

Nusa, as correctly denned, is distinctive in appearance. The wing-margin is membranous shortly beyond R^, the first and fourth posterior cells typically closed with a long, or very long stalk, and the veins tending to fade before reaching the wing-margin. The characteristic appearance of flies of this genus is enhanced by the stiff bristles on all parts of the body, including the head.

Species have been recorded in the genus Dasythrix from all the zoogeographical regions except the Nearctic, but it is by no means certain that they all belong properly in Nusa. Among the African species there is extensive sexual dimorphism, the males tending to be distinctly blacker than the females, and with black hairs everywhere instead of white ones. There is, however, variation in this, and among a complex of specimens there are many males with black moustache and some with the moustache white, though no clear differences can be seen in the genitalia. It seems likely that Loew's three species from the Cape — infumata <$, brachyptera $ and stenura $ — may be synonyms, but this cannot be determined until types can be examined.

No species of Nusa has yet been recorded from the Pare national du Garamba. The genus is unlikely to occur in the forested areas, but may be found in the savanna fringe close to the border with the Sudan. Besides the S. African infumata-com- plex, mentioned above, which extends as far north as the Katanga, there are five other described species from the Ethiopian Region : nigrapex Bigot from Natal ; dispar Gerstaecker from Zanzibar ; vittipes Bezzi from Somaliland ; ruficornis Wulp from South Yemen and albicans Engel from Rhodesia.

PERASIS Hermann

Perasis Hermann, 1905 : 37 ; Engel, 1924 : 104-5. Type-species : Perasis sareptana Hermann,

1905, monotypic. Saucropogon Hull, 1962 : 103. Type-species : Perasis transvaalensis Ricardo, 1925, by original

designation.

This genus was clearly defined by Hermann, but has been misinterpreted by Hull (1962 : 93), who removed the S. African Perasis transvaalensis Ricardo to be the type of his new genus Saucropogon (1962 : 103). Hull saw the type and other specimens of transvaalensis in the BMNH, and he also gives drawings of sareptana Hermann, though he did not see this species in the BMNH, where it is not represented.

The characters given by Hull (1962 : 103) to define Saucropogon, and to differ- entiate it from Perasis, concern mainly the wing-venation and the head-structure, and in fact are the very characters by which Hermann himself defined Perasis (1905 : 37). Hermann's fig. 28 shows the venation that Hull says is characteristic

ASILIDAE OF THE CONGO BASIN 245

of Saucropogon. It seems evident that Hull has based his interpretation of Perasis on specimens that were not P. sareptana Hermann, since, among other things, he says that they have lateral bristles on all the abdominal segments, whereas Hermann's Perasis has bristles on the first segment only.

The type material of transvaalensis Ricardo agrees with Hermann's definition of Perasis, and must therefore revert to that genus. This makes Saucropogon Hull, type transvaalensis Ricardo, an absolute synonym of Perasis Hermann.

The species of Perasis are few and poorly known, scattered from Transcaspia across North Africa. Hermann (1920 : 177) gave a list of four names in addition to the type-species : postica Becker and violacea Becker, both from Algeria ; Dasypogon maura Macquart from Oran ; and Perasis meridionalis Hermann from the Transvaal. Engel (1925 : 104-5) explained that this last name was a nomen nudum, no description having been published, and that it appeared to refer to specimens in Hermann's collection which at the time Engel saw them bore the manuscript name capensis. In the same year Ricardo (1925 : 245) described Perasis transvaalensis from the Transvaal, and also recorded meridionalis Hermann as a nomen nudum.

The theory that Dasypogon maura Macquart, 1849, *s really a Perasis appears to come from Hermann (1920 : 177) but he gives no reasons for believing this. Bigot (1878 : 221), in whose collection the type was deposited, thought that it might belong to Habropogon.

No Perasis is known to me from within the boundaries of the Pare National du Garamba, but the BMNH possesses a specimen from the Bunyoro district of Uganda that is specifically distinct from transvaalensis, and Monsieur Francois collected a number of the same species from Urundi.

Perasis carpenteri sp. n.

Closely allied to Perasis transvaalensis Ricardo, but with several constant colour- differences. Most obviously, the pleura are uniformly covered with yellow-grey tomentum over a black and red ground colour ; whereas the pleura of transvaalensis are distinctly striped, with the anterior-facing areas of mesopleuron and sterno- pleuron shining black through thin brown tomentum, and the posterior-facing areas covered with thick yellow-grey tomentum. In carpenteri the whitish hind margins of the abdominal segments are uniform in breadth, whereas in transvaalensis they are expanded laterally and constricted in the middle.

$ Head black. Frons and face with a dense tomentum or pile, which is white when the light falls from one direction. Moustache limited to about ten strong black bristles on mouth- margin and a few scanty hairs above this ; most of face with tomentum only, no strong hairs or bristles. A few white hairs in beard, otherwise hairs and bristles of head are black. Anten- nae black or a little reddish, palpi and proboscis black, all with black bristles.

Thorax. Mesonotum black, reddish only on humeri and postalar calli. These areas have some whitish tomentum, which spreads across hind margin of mesonotum, immediately before scutellum. Mesonotum otherwise with very short, adpressed, dark brown hairs ; scutellum, in contrast, with yellowish adpressed hairs. Pleura reddish in ground colour, but with a big black area anteriorly on meso- and sternopleura ; the whole pleural area covered uniformly

246 H. OLDROYD

with yellowish grey tomentum, without the rather bare vertical stripe that is seen in trans- vaalensis. Metapleural tuft of black bristles.

Abdomen. Dorsum dull black, obscured by very short, adpressed, black hairs. Each segment posteriorly with a narrow band of uniform width, reddish in ground colour, with whitish tomentum. Venter similar, black hairs rather longer.

Legs. Coxae reddish in ground colour, with pale yellowish hairs. Femora black with short black hairs ; tibiae and tarsi dull reddish, covered with yellowish white hairs, but all leg- bristles black.

Wings. Veins black, not partly yellowish as in tmnsvaalensis. Fairly uniformly stained brown, only slightly paler towards wing-margin. Venation as in transvaalensis, but with stalks of closed cells a little longer.

Length. Body 13 mm ; wing n mm.

$ Generally similar, but with a few differences. Frons and face with more yellowish white hairs, especially in space between membrane and bases of antennae. Mesonotum covered with adpressed yellowish grey hairs like those of scutellum, and with a very narrow median line and a pair of postscutellar spots formed from dark brown hairs. Femora dull reddish in ground colour and covered with adpressed pale hairs instead of dark.

HOPLISTOMERUS Macquart

Hoplistomerus Macquart, 1838 : 59, Oldroyd, 1940 : 307. Type-species : Laphria serripes Fabricius, 1805, monotypic.

In 1940 (loc. cit.) I published a synopsis of the species of this genus, demonstrating how the genus extends over the Ethiopian Region, with the exception of the equatorial forest. A miscellany of species exists in eastern Africa, from Lake Nyasa to the Red Sea, and from this nucleus one species, H. serripes Fabricius, has spread through the northern savannas to the Gambia, while another, H. nobilis Loew, goes southwards to the Cape and S.-W. Africa.

The presence of a species of Hoplistomerus in the Pare National du Garamba is therefore rather surprising, until one looks at the description of the localities con- cerned : 483 — savane arborescente, sur les herbes ; 529 — galerie forestiere seche ; 3282 — savane arborescente ; 3298 — herbacees sur le pourtour d'une prairie. In localities such as these a savanna fauna is able to establish itself within the confines of the Pare.

Hoplistomerus garambensis sp. n.

(Text-figs 26, 27)

Most closely resembles H. erythropus Bezzi, from Somalia, from which species it differs in having black stripes on the femora ; in the abdominal colouring, which is more normal for the genus than it is in erythropus ; and in the male genitalia. (Text- figs 26, 27).

$ Head. Black, obscured by thick, yellowish tomentum, except for a bare patch of variable extent in centre of face. Hairs and bristles all yellow or whitish. Antennae blackish or dull reddish, with yellowish hairs. Palpi pointed and rather swollen, with hairs mainly black, some

ASILIDAE OF THE CONGO BASIN 247

yellow ; proboscis black with silvery hairs at base (part of beard) and deep yellow ones at apex. Beard silvery, occipital bristles yellow.

Thorax black. Mesonotum heavily punctured, with little or no tomentum, but covered with golden yellow hairs, white at sides ; a row of 5-6 supra-alar and one postalar bristles yellow or whitish, otherwise dorsum without bristles. Scutellum covered with yellow tomentum and very short, golden yellow hairs ; a deep, transverse groove is bare, shining black ; no marginal bristles. Pleura black with thick white tomentum ; meso- and sternopleura with a large shining black area.

Abdomen black^ Each segment narrowly shining black basally, otherwise covered with long, adpressed, curled, golden yellow hairs. Laterally a patch of these adpressed hairs is silvery white. First five complete segments each has 1-4 strong bristles laterally. Venter rather bare, black-brown, with thin grey tomentum and sparse pale hairs. Male genitalia as in Text-fig. 27.

Legs. Coxae like pleura, black with thick white tomentum and white hairs. Trochanters, femora, tibiae and tarsi orange, only femora with dorsal black stripe over middle part of their length. Short clothing hairs white, even on tarsi ; bristles yellow. Ventrally on hind femora the tubercles as usual in Hoplistomerus.

Wings. Venation normal for genus. Marginal cell closed on margin, vein Rz+3 recurrent. First and fourth posterior cells closed with short stalk. Dark microtrichiae form the usual two cross-bands across base of discal cell, and from radial fork to apex of wing, the two united posteriorly. Veins blackish brown in dark areas, orange in clear patches.

TRICHARDIS Hermann

Trichardis Hermann, 1906 : 137 ; 1920 : 177. Type-species : Laphria testacea Macquart,

1838 ( = Trichardis testacea Hermann, 1906), by designation of Hermann, 1923.3 Strobilothrix Becker, 1907 : 42. Type-species : Strobilothrix albipila Becker, 1907, monotypic.

Closely allied to Hoplistomerus Macquart, and not easy to separate clearly from that genus. Hermann's first two species, testacea and picta, were distinguished by the absence of the conspicuous wart-like excrescences beneath the hind femora, but in other species which he later assigned to Trichardis the ventral spines arise from smaller, but distinct protuberances. As I recorded in 1940 (p. 310, note), the late Dr S. W. Bromley considered that Trichardis was only a subgenus of Hoplistomerus, but I am still not sure that I agree with this view. In general facies the two genera seem to be distinguishable, Hoplistomerus being more robust. Probably they can be formally separated by the different relative length of the first segment of the hind tarsus, as well as by the male genitalia, Hoplistomerus having the claspers prominent and usually hooked.

Since Trichardis does not appear to penetrate into the Congo Basin proper, this is hardly the place in which to attempt a detailed study of the genus, but one new species from the south-eastern uplands may be noted.

3 Engel (1924 : 106) stated categorically that Laphria testacea Macquart was a Storthyngomems, and was quite different from Trichardis testacea Hermann. This is not in agreement with Macquart's original description, in which the antennae are described as 'assez courtes'. Dr. L. Tsacas has very kindly examined Macquart's type in Paris and confirms: (a) that it is definitely a Trichardis and not a Storthyngomerus ; and (b) that it agrees with the description of Trichardis testacea Hermann.

Very closely resembling T. cribrata Loew, but distinguished by the much larger bare area of the mesopleuron (Text-figs 28, 29), and by the larger and more con- spicuous white patches in the posterior angles of the abdominal tergites.

<J$ Head. Black with thin white tomentum. Four strong black ocellar bristles ; sides of frons with one or two short black bristles, but also softer white ones. Moustache consisting of a few black bristles on mouth-margin, and longer, silvery hairs and fine bristles rooflike above these, extending at sides almost up to bases of antennae. Centre of face with some fine black hairs. Antennae may be entirely black, or more or less reddish, especially first two segments. Proboscis and palpi black, but with hairs mainly silvery. Fine, silvery hairs in beard and over occiput, but postocular bristles strong and black.

HYPERECHIA Schiner

Hyperechia Schiner, 1966 : 673 ; Marshall, 1902 : 287-584 ; Griinberg, 1907 : 515-524 ; Thorpe, 1927 : 177-185 ; Lamborn, 1927 : 44-47 ; Engel, 1929 : 147-162 (larva) ; van Bruggen, 1962 : 313-317. Type-species : Laphria xylocopiformis Walker (an Indian species), by original designation.

Flies of this genus are well-known because of their close resemblance to Xylocopid bees. They are short and broad, with strong legs fringed with long pile, and with wings broad basally, pointed at apex. The head is broad, the third antennal segment long and clavate. The flattened, leaf-like palpi are characteristic of those genera which Hull (1962 : 349) unites into the tribe Andrenosomini. The genus Hyperechia is characterized by general appearance rather than by any diagnostic character. Systropalpus Hull (1962 : 355), mentioned in the key to genera, is based on a single male from Ethiopia, which I have not seen.

The various species differ in the distribution of white, yellowish or reddish pile on the mesonotum, scutellum, abdominal segments 1-3, and legs. Several species bear a startlingly close resemblance to particular species of Xylocopa, and to this

250 H. OLDROYD

extent they may be said to mimic the bees, especially as the larva of the fly lives in the burrows of the bee, and the adult flies are found in association with the adult bees. Yet Hyperechia adults are often taken in association with Xylocopa other than the species to which they bear a mimetic resemblance. An example of this occurs in the collections from the Musee du Congo, where a specimen of Xylocopa flavorufa Deg. from Abok in the Ituri is labelled as having been taken in association with Hyperechia imitator Grim. ; but the species of Hyperechia which imitates this species of Xylocopa is H. bomboides Loew, which occurs at Tchad and similar drier regions.

The following key is presented as an interim guide to the species, more particularly those of the Congo Basin, or which might occur there.

PROAGONISTES Loew

Proagonistes Loew, 1857 : 362, 367 ; 1860 : 170 ; Bromley, 1930 : 209-224. Type-species : Proagonistes validus Loew, monotypic.

These large, aggressive-looking robber-flies are distinguished by their powerful, sickle-like proboscis, usually upturned at the tip, and by their bare, elongate appear- ance, mimicking some of the bigger wasps, especially Psammocharid wasps of the genus Salius.

Neave (quoted by Bromley, 1930 : 213) associated flies of this genus with forest, or at least with woodland, and wrote : ' I have never found them except in associa- tion with trees.' Specimens from the Congo Basin suggest that Proagonistes is not typical of high forest, but occurs along the great rivers, on the forest fringe, and in savanna woodland.

The genus is quite closely related to Andrenosoma Rondani, and it is not easy to indicate constant differences between the two genera, though each has a recog- nisable fades. Proagonistes is more elongate, with long, slender legs, and cylindrical abdomen which is scarcely constricted basally. In the wing the first posterior cell is wide open, with veins R$ and MI parallel, or even diverging slightly. Andreno- soma is typically more bee-like, the abdomen broader, and often constricted basally ; the hind legs stouter, with distinct long hairs on tibiae and tarsi in addition to stout

252

bristles ; and in the wing the first posterior cell is narrowed, often closed and stalked.

Bromley (1930 : 209-224) published a revision of the genus Proagonistes, to which may be added two species of hitherto doubtful affinities : Nusa africana Ricardo, and Proagonistes igniferum Engel and Cuthbertson, both of which have at some time or other been assigned to Andrenosoma. One new species from the Congo Basin is described in the present paper.

Shares with P. apicalis (Curran) and P. redimiculum Speiser the orange, black- banded mesonotum, but is distinguished from apicalis by the wholly dark wings, and from redimiculum by the conspicuous red tip to the black abdomen. This involves the sixth and following segments, and the ovipositor is distinctly shorter than that of $ redimiculum.

$ Head. Red. Ocellarium has a small, black patch running longitudinally, not transverse as in redimiculum. Frons otherwise rather bare and shining brown ; rest of head, including buccae and occiput, orange with orange tomentum, bristles and hairs ; only a small tuft of whitish hairs in beard. Palpi red with orange hairs. Proboscis red at base, shining black for most of its length, but with orange hairs. Antennae orange with orange hairs, third segment about twice as long as first two segments together.

Thorax. Orange with black pattern. On mesonotum a pair of longitudinal black stripes from anterior margin almost to reach scutellum ; on each side a roundish black spot before transverse suture and an elongate triangular black spot posteriorly. Scutellum entirely orange. Sides of pronotum, propleuron, mesopleuron and sternopleuron with round black spots ; otherwise pleura orange with tomentum that is mostly white, especially ventrally and pos- teriorly. Postnotum (' metanotum ') orange with a pair of black spots.

Abdomen. First five segments dorsally and ventrally black with black-brown tomentum and predominantly black short hairs ; some orange hairs laterally on tergites, where there are one or two orange bristles on all five segments. Sixth segment and posteriorly bright orange with orange hairs.

Legs. Coxae like pleura but with white hairs as well as white tomentum ; legs otherwise entirely orange, with orange or yellow hairs ; only claws apically black.

Wings. Entirely black-brown, with orange hairs on base of costa. Halteres orange.

Length of body 23 mm ; of wing 20 mm.

The rest of the colour- pattern is so striking, with the bright red head, thorax and legs, coupled with black pleura, abdomen and wings, that I think we must accept the two as conspecific.

ANDRENOSOMA Rondani

Andrenosoma Rondani, 1856 : 160 ; Hull, 1962 : 349. Type-species : Asilus ater Linnaeus, 1758, monotypic.

The affinities of this genus are discussed briefly under Proagonistes. Andrenosoma occurs in all the major zoogeographical regions, but is an enigmatic genus every- where ; the huge Andrenosoma of Australia and South America have little obvious affinity with the three distinctive Palaearctic species. The species of tropical Africa have been particularly obscure, since they have never numbered more than one or two, and these have been questioned, and in some cases transferred to other

At present only two remain, separable as follows :

ASILIDAE OF THE CONGO BASIN 257

Tribe ATOMOSIINI

The tribe Atomosiini is a compact group of Asilidae, which look rather like small solitary bees. They are united by a peculiarity of wing-venation, in which the veins forming the posterior, apical angle of the discal cell form a cross +, or a dis- placed crossing -y. Though apparently trivial, and occasionally to be found in other tribes, this detail is a very constant point of recognition. Hull (1962 : 369) points out that almost diagnostic of this tribe is the sclerotization of the area immediately behind the hind coxae, but this detail is not so easily observed as the wing- venation.

Atomosiini are divided into a very large number of genera, most of which are confined to South America. Hermann (1912) established most of them. These genera are justified by the number of structural variations that occur, especially in the head and antennae, but it is doubtful how far these differences are of generic value. The tribe is generally placed in the subfamily Laphriinae, but a much fuller study is needed to establish its true relationships, (cf. Karl, 1959).

In the Ethiopian Region only a very few species of Atomosiini have been des- cribed. Hermann created the genus Goneccalypsis for Atomosia argenteoviridis Hermann from the Transvaal. Engel (1929) described Loewinella nigripes from Southern Rhodesia as a variety of the Palaearctic L. virescens (Loew), but it seems clear that this should be treated as a distinct species. Loewinella aphaea Se"guy (1950) comes from the oasis of Air (Agades) in the Sahara, and Curran (1927) described an Atractia arcuata from Stanleyville.

The last species is well represented in the collection of the Muse"e du Congo, and is not "an Atractia (as, indeed, Curran suspected) ; it is clearly congeneric with Loewinella nigripes Engel.

Tribe SAROPOGONINI

Modern attempts to improve upon Loew's division of the Asilidae into four sub- families find most difficulty in subdividing Loew's Dasypogoninae. Workers in each region tend to give prominence to genera that are peculiar to their own region : thus G. H. Hardy (1934), a pioneer of tribal classification in Asilidae, erected tribes Phellini, Chrysopogonini and Brachyrrhopalini that are all restricted to Australasia ; while Carrera (1952) recognized a tribe Megapodini for certain S. American genera.

The world classification of Hull (1962) goes further than any other, breaking the old Dasypogonihae into twelve tribes. At the present stage of knowledge of the

258 H. OLDROYD

African Asilidae it is not profitable to comment critically upon this arrangement, beyond saying that it appears to raise problems in placing certain genera. I shall therefore continue to use the classification set out in my earlier paper (Oldroyd, 1963), and divide the old Dasypogoninae into three tribes : Saropogonini, Sticho- pogonini and Xenomyzini. Of these, Saropogonini are recognized by having the prosternum completely separated from the pronotum, and appearing as a small sclerite surrounded by membrane. This is usually visible from the side, or below, though it may be necessary first to brush off some of the obscuring hairs.

Out of the 26 genera included in my key to African Saropogonini (Oldroyd, 1963 : 6) the present collection contains only eight, together with one new genus, Dogonia. There is therefore little point in reprinting the key, but a few notable absences may be recorded. Sisyrnodytes and Acnephalum, Saropogon and Steno- pogon are generally associated with somewhat arid terrain ; Habropogon, Holopogon and Heteropogon are essentially subtropical or Mediterranean genera : Hypenetes, Lycostomus, Teratopus, Hermanella and Spanurus are found in more southerly parts of Africa, although any one of these may yet be found within the Congo Basin.

NEOLAPARUS Loew

Laparus Loew, 1851 14; [nee Laparus Billberg, 1820, Lepidoptera] . Type-species : Laparus

tabidus Loew, by original designation. Neolaparus Williston, 1889 : 255 [new name]. Cenopogon Wulp, 1898 : 120. Type-species : Cenopogon bifidus Wulp, monotypic.

Specimens of Neolaparus are abundant in collections of African Asilidae, and are extremely difficult to classify. Structurally they are remarkably uniform. The face bulges a little below the antennae, and projects as a rim on the epistoma, but has no clearly defined knob, and the moustache is very sparse, generally consisting of two or four stiff bristles with at most a few fine hairs. Only rarely is there a more extensive moustache. The third antennal segment is usually clubbed, and is elongate only in one or two species. The male terminalia are fairly elaborate, and show some inter-specific variation, but only rarely is this decisive enough to be diagnostic. The wing-venation is primitive, and remarkably uniform.

The species therefore are mostly defined by colour and pattern, chiefly of the thorax and abdomen. These are reasonably reliable in well preserved specimens, but unfortunately are quickly ruined by bad preservation. A great majority of all specimens available for study are badly greased, and one can only guess at their natural appearance.

As long ago as 1860 Loew made very similar comments about the difficulty of classifying species of this genus, which he divided into two sections, one with only two strong bristles on the epistoma, and the other with four or even six. Bromley (1956 : 140), while using this arrangement in his key, wrote : ' This is not a good grouping, as the number of bristles may vary within a species '. There is, never- theless, evidence of a division of the genus into two groups of species, the one con- sisting of larger and darker flies, the other more fragile and paler in colour. The first group have the alula of the wing larger, and with a distinct posterior angle,

ASILIDAE OF THE CONGO BASIN 259

whereas the flies of the second group have the alula smaller, and with its posterior margin only slightly convex.

Hull (1962 : 256) says that : ' Both sexes of Lagodias may be separated from the related Neolaparus and also from Pegesimallus by the absence of the ventral hypopleural patch of dense pile '. This is true of the type-species of each genus, but is not a valid generalization. This patch of pile is widespread among many genera of this and other tribes, e.g. Laphria, but it appears sporadically, and may be present or absent in species that are clearly congeneric.

The species of Neolaparus are in such confusion that it seemed better in the present paper to mention only those few specimens that come from the Pare National du Garamba, deferring a more general account of the Neolaparus for a more com- prehensive revision. Curran's key (1934) is a useful guide if it is used with caution, but no really satisfactory key to the species of Neolaparus has yet been produced.

Neolaparus decoratus sp. n.

A well-marked species, of distinctive pattern. Resembles ophion Speiser in having microtrichiae entirely covering the wing, and not confined to an apical area, but differs in having a clear-cut abdominal pattern, and in the bicoloured, strongly clubbed antennae.

$ Head. Pronto-facial area broad, not greatly narrowed at antennae, black in ground colour, but obscured by thick tomentum. On frons this tomentum is brassy brown, more yellow along eye-margins and just above antennae, where there is a short, vertical black stripe. Face quite prominent at epistoma, but triangular in profile, with flat upper surface, tomentum yellow-

260 H. OLDROYD

brown, white laterally ; only two strong, pale bristles on epistoma, and a few short, pale yellow hairs. Probosics and palpi black, with black hairs. Antennae with first two segments yellow- brown, short, subequal, with yellow bristles ventrally, black ones dorsally ; third segment strongly clavate, pale yellow at base, black on expanded portion. A pair of yellow postvertical bristles. Occiput with yellow tomentum and a few yellow hairs.

Thorax olive-brown, with indistinct, divided, median stripe, outlined by very narrow dark brown lines, as in ophion. Very short black hairs, each arising from a dark spot, run along lines of dorsocentrals, and cover a large posthumeral area, as well as the rather paler lateral margins of the mesonotum. Bristles yellow, very strong, restricted to one notopleural, one supra-alar, and one postalar. Scutellar disc concolorous with mesonotum, but rim dark red-brown ; short hairs in line with dorsocentrals, but no bristles.

Pleura with brassy yellow tomentum, through which the ground colour is visible : pronotum and propleuron, mesopleuron, sternopleuron, hind coxae and a little of the other coxae show a dark ground colour ; pteropleuron, mesopleuron and metanotal callosities have a yellow ground.

Abdomen black, with a dull sheen, and therefore contrasting strongly with thorax. Dorsally first segment and base of second with bronze tomentum, leaving bare the bulla on the second segment (a feature of Neolaparus and Lagodias). Segments 2-6 each has a pair of spots of white tomentum : on second segment these are short, transverse lines, and occur at half-way position ; on each succeeding segment they become further forward until on sixth they are small spots on fore margin. These segments also have on extreme lateral margins a spot on anterior border and a short band in posterior angle. Hairs very short, very scattered, black. Venter shining black with grey hind margins. Segments 7, 8 shining black, forming an ovipositor.

Legs. Long, slender, all femora and tibiae slim on basal half, distinctly thickened towards tip. Generally chestnut-brown in colour, but femora pale on narrow basal stalk and black- brown over thicker apex. Clothing hairs black, long bristles yellow.

Wings. Venation normal, all cells open. Microtrichiae cover entire wing membrane, as in ophion, and do not form a grey tip. Alula very shallow, gently curved.

Length of body 13 mm ; of wing n mm.

LAGODIAS Loew

Lagodias Loew, 1857 : 345 ; 1860 : 69. Type-species : Lagodias albidipennis Loew, 1857 ; by monotypy.

The males of Lagodias are conspicuous in having some part of the legs, and especially of the hind legs, with a spectacular fringe of flattened, scale-like hairs. Apart from this feature they are typical Neolaparus, and the females are very difficult to recognize as Lagodias. Hull (1962 : 256) claims that both sexes of Lagodias can be distinguished from Neolaparus by not having the small, dense tuft of short hairs on the hypopleuron, but, as we have already seen, this is not found in all species of true Neolaparus.

The practical effect of this feathering of the legs is an interesting question. Hermann (1906 : 144) stresses that this is a secondary sexual character, and that the extent of the feathering varies in different species. It may be found on the tarsus only ; on the tarsi and apically on the tibiae ; on tarsi and tibiae, but not on femora ; or on all segments of the hind and middle legs. The shape of the individual scales varies, too, from slightly flattened hairs to large scales, flattened like a paddle- blade or a banana leaf.

ASILIDAE OF THE CONGO BASIN 261

Hermann also speculates about the possible function of the feathered legs : ' Then one can hardly avoid the conclusion that this monstrous feather-apparatus must seriously handicap the insect, which is far from robust, and it can therefore be imagined that the insect possibly hunts its prey over the smooth surface of water, and that when the feathers are erected they may form a swimming paddle.'. He wisely adds that this remains mere speculation until observations on the habits of these flies can be recorded — observations that are still wanting, nearly sixty years later. On the whole Hermann's guess seems rather unlikely, the more so since both sexes seem to have the same hunting habits. Is it not more likely that the ornamentation of the legs of the males contributes to sexual display, and that the so-called genus Lagodias is no more than a collective name for those species of Neolaparus in which the males have developed such sexual ornamentation : com- pare, for example, the genus Dolichopus?

The collection from the P.N. Garamba contains only a single specimen, which cannot be referred to any known species.

Lagodias griseus sp. n.

Distinguished from most of the known species of Lagodias by the fact that the scales of the middle and hind legs completely cover the tarsi and the tibiae, but there are none on the femora. There is at least one other unidentified species with this type of ornamentation, but the present species is unique in having the thorax almost entirely dusted with white, and only indistinctly darker paired longitudinal stripes are visible. Wings nearly white, with pale veins.

c£ Head. Shaped as in those species of Neolaparus that have a broad front, and have facial hairs in addition to the two strong bristles. Fronto-facial area almost as broad as one eye, scarcely narrowed at antennae. Evenly covered with white tomentum, and with white hairs. Two strong, white bristles on epistoma, and many white hairs forming a moustache, but not extending more than half-way to antennae. Proboscis and palpi black with mainly black hairs. Antennae blackish, with pale constrictions between the segments, and at base of third segment : hairs long, white ventrally, shorter and black dorsally. Occiput uniformly covered with white tomentum, and with numerous silvery white hairs, among which the pair of white postverticals are almost lost.

Thorax black, with a thick covering of white tomentum, with no pattern except for a paired longitudinal stripe which appears blackish because the tomentum is thinner there. Abundant very fine white hairs curled upwards (compare Pegesimallus) . Strong bristles are i notopleural, i supra-alar, and i postalar. Scutellum with erect, soft, white hairs all over disc, but no strong bristles.

Abdomen. Dorsum shining black, with a purplish sheen. White tomentum covers first tergite, and surrounds bulla on second, as well as forming a pair of prominent white spots of segments 2-6. Venter shining black with yellow segmentations. Genitalia black, epandrium reddish.

Legs. Elongate and slender, femora and tibiae swelling to a knob at apex. Femora and tibiae yellow basally, otherwise legs red-brown or dark brown. Fore legs without ornamenta- tion. Middle and hind legs each with no scales on femora, and with a broad, conspicuous, double fringe of dense black-brown scales, which continue without diminution to apex of fifth tarsal segment. Normal vestiture of short black clothing hairs and white stiff bristles present on all legs.

PEGESIMALLUS Loew

Pegesimallus Loew, 1857 : 344 '• 1860 : 69. Type-species : Pegesimallus ursinus Loew, monotypic.

As stated above, Pegesimallus is closely related to Neolaparus, and only to be distinguished by being covered with abundant, rather long, soft hairs. Hull's claim that Pegesimallus, like Neolaparus, has the small, compact hair-tuft on the hypopleuron, whereas Lagodias has not, is apparently not valid. The present specimen has no such tuft, although in proportions of body and head, as well as in general hairiness, its affinities clearly lie with Pegesimallus ursinus rather than with the stark, bare flies that are typical of Neolaparus.

Three species have been described in Pegesimallus, all from southern Africa. The present species differs from all of these in the much greater length and density of the hairs clothing the hind leg (Text-fig. 37). Neolaparus morio Bezzi from West Africa, and one or two undescribed allied species, ought perhaps to be transferred to Pegesimallus, if this genus is to be maintained at all.

Pegesimallus saegeri sp. n.

(Text-fig. 37)

A dull black, or black-brown species, with brown antennae and legs. Middle and hind legs exceptionally hairy, but not scaly as in Lagodias, hairs longer and denser than in any other species.

o* Head. Fronto-facial area parallel-sided, about two-thirds as broad as one eye. Antennae at upper third. Frons black, with thin brown tomentum. A row of black hairs on each side runs from vertex and crosses diagonally to base of each antenna. Face produced at epistoma about as far as length of palpi, but with a flat profile, no facial hump (compare Lycostomus). Covered with dense brown-grey tomentum. Moustache black, composed of two strong bristles and a mass of black hairs, which does not quite extend up to antennae. Palpi cylindrical, or very slightly thickened at tip, first segment tiny and inconspicuous ; black, with very long black hairs. Proboscis black. Antennae chestnut-brown ; first two segments subequal ; third constricted basally, slightly clavate, microsegment at tip almost undetectable, with a small apical spine ; hairs and bristles black, third segment with a number of short black bristles dorsally and externally. Occiput with brown tomentum and a mass of fine black hairs, a pair of strong black postvertical bristles, and one or two others concealed among the fine hairs.

Thorax. Mesonotum strongly convex, but in a uniform curve, not projecting anteriorly ; covered with thick, black-brown tomentum, with only faint traces of a pair of median longi- tudinal stripes, and more reddish on lateral margins. The mane of fine black hairs is less dense than in Pegesimallus ursinus Walker, and is confined to the dorsocentral stripes, a large area behind each humeral lobe, and broad lateral margins. Strong black bristles comprise one notopleural, one supra-alar, and one postalar, with some bristly hairs nearby. Scutellum with

ASILIDAE OF THE CONGO BASIN

no bristles, and with a tuft of hairs on each side in line with supra-alars (as in many species of Neolaparus). Pleura black-brown, with rather long black hairs on most sclerites, but no trace of a dense little patch on hypopleuron.

Abdomen black, only faintly reddish at sides of first three tergites. Covered with black tomentum, seventh tergite with a pair of large areas of shining black. Hairs both dorsally and ventrally long, dense, and erect. Abdomen a little narrowed basally into a waist, but after fifth segment it is laterally compressed. Male genitalia of similar construction to those of Neolaparus, mostly shining black, but epandrium and aedeagus red.

Legs. Long and moderately slender, chestnut-brown. Hind femora a little stouter than in typical Neolaparus, but made to appear more so by the long, dense, black hairs, as shown in Text-fig. 37. Bristles few, and scarcely to be distinguished from the surrounding hairs. Middle legs similar, fore legs rather less hairy. Coxae with tomentum and hairs like those of pleura.

Wings. Venation normal, only anal cell closed on wing margin. Alula small, rounded. Membrane stained almost uniformly yellow-brown.

Length of body 15 mm ; of wing 12 mm.

This is another very large and difficult genus, in this respect resembling Neolaparus, and equally in need of a thorough revision, taking into consideration all the species throughout the Ethiopian Region. The study of Microstylum is further complicated

by the existence of a large number of species in Madagascar, where they form a striking part of the Asilid fauna. Some species are amongst the biggest flies in the world.

The present collection from the Pare National du Garamba contains only three specimens of Microstylum, belonging to two species, both of which have a spur-like prolongation of the tip of the middle tibia (Text-fig. 39). This brings them into Mimoscolia Enderlein, which Hull (1962 : 160) regards as a full genus, though other authors have considered it to be at most a subgenus of Microstylum. Its status may be even less than that : it is possible that those species with some form of prolon- gation of the middle tibia are not even a species-group, but merely unrelated species that happen to have this detail in common. This view receives support from the fact that M. cilipes Macquart and M. mydas Engel, both from Madagascar, have a process of a sort, not on the tibia, but on the basitarsus of the middle leg, perhaps serving a similar practical purpose. Hull (1962) puts mydas in Microstylum and cilipes in Mimoscolia, though Engel (1932) puts them into the same couplet of his key.

Bezzi (1908) described two genera from the Congo Basin that are very closely allied to Microstylum. Eclipsis, monotypic for maculiventris Bezzi, is distinguished from Microstylum by having the first posterior cell of the wing closed, and the costal vein not extending much beyond R± ; while EpibUpharis , monotypic for pedunculata Bezzi, has the second posterior cell, of characteristic shape in Microstylum, pedun- culate rather than sessile on the tip of the discal cell. Hull (1962 : 158, 159) rightly suspects that these may be no more than anomalous species of Microstylum. One badly preserved specimen from the Mayumbe, in the collection du Muse"e du Congo, could be Epiblepharis pedunculata, but if this is correctly identified it supports Hull's view, because the second posterior cell is sessile in one wing, and barely pedunculate in the other.

The following key is extremely incomplete, especially in regard to species des- cribed by the older authors from the Cape. It is given because it covers most of the species described from the Congo Basin or areas immediately adjacent, and because the existing keys deal mainly or partially with the many Microstylum from Madagascar.

Microstylum pollex sp. n.

(Text-fig. 39)

A species of moderate length (19 mm), rather small for a Microstylum ; black, with dark wings, and heavily tomented abdomen. Belongs to the group Mimoscolia Enderlein because of its spur to the middle tibiae. Nearly all the known members of this group occur in Madagascar, and apart from the distinctly banded helenae (see above), the only mainland species recorded is braunsi Engel from the Cape. This differs from pollex in the shape of the mid-tibial process, the colour of the legs, and the predominance of black bristles on the head.

Microstylum ricardoae sp. n.

Long ago, Miss Ricardo set aside two female Microstylum in the BMNH collection from Kambove, in the Katanga, as ' $ of nigribarbatum Bigot, or sp. nov.' In the collection of the Musee du Congo Beige is a series of females of the same species, and one male, clearly conspecific, and all from the vicinity of Elisabeth ville. It thus becomes apparent that Miss Ricardo's species is not the female of Bigot's, but should be described as new. It is easily distinguished from nigribarbatum by having the hind femora and hind tibiae conspicuously clothed with white hairs.

$ Head black, thickly covered with yellowish grey tomentum, more brownish on frons, paler on face. Frons with bristly black hairs in multiple rows along each eye-margin. Face bare except for a dense moustache of stiff bristles which may be either bright yellow or whitish, on a tubercle that occupies lower half of face. Palpi and proboscis black with black hairs. Beard silky, black ; occipital bristles and hairs nearer eye-margins, black ; inner part of occiput with silky white hairs.

Thorax dull black, with rusty brown tomentum and black hairs and bristles. An abundant covering of fine hairs as well as strong bristles at sides of mesonotum and on scutellum (2 strong, 2 sometimes weaker) ; no supra-alars. Pleura also with many fine black bristles, including pteropleuron which, however, has no strong bristles.

A bdomen black, dorsally and ventrally sharply divided into a dull anterior half and a shining posterior half. First four segments entirely obscured by black tomentum, but with short white clothing hairs. Segments 5-8 shining black, bare.

Legs. Black : coxae with dense, long, black hairs, no obvious strong bristles ; rest of legs with predominantly white clothing hairs, especially on hind femur, tibia and basitarsus ; else- where with some black hairs and bristles.

Wings uniformly rusty brown. Halteres black.

Length of body 27 mm ; of wing 21 mm.

cJ very similar, except that all the abdominal segments are dull, without a shining black tip.

DOGONIA gen. n.

Type-species : Dogonia saegeri sp. n., by present designation.

Related to Scylaticus Loew and to Cyrtopogon africanus Ricardo, but easily dis- tinguished from both by having the metanotal callosities hairy. Hull's key (1962 : 119) to his tribe Stenopogonini recognizes only seven genera of this tribe that have hairy metanotal callosities, and three of these belong to Microstylum sensu lat. In Hull's key the new genus runs down to Neodysmachus Ricardo, but is quite different in appearance from that elongate, bristly, Australian genus. In general appearance Dogonia looks like a Saropogon, but without the fore tibial spurs.

Head (Text-figs 42, 44). In profile eyes shallow, occiput conical, exposing a large surface, which has long, fine hairs but no stiff bristles. Seen from in front, face is parallel-sided, almost one quarter of head-width ; eye-margins excavate above antennae (Text-fig. 44). Ocellar tubercle large, but sunk below level of vertex. Antennae with two rather short, subequal segments, then an awl-shaped third segment, ending in a short, conical, microsegment, and a distinct apical style. Face gently convex in upper half, lower half expending smoothly into a distinct knob ; moustache confined to this knob. Palpi two-segmented, little longer than epistoma ; both segments subequal, second a little swollen basally, narrowed apically, with apical pit and style. Proboscis as long as height of eye.

Thorax not structurally remarkable.

Abdomen. Depressed cylindrical, tapering a little apically, like that of Saropogon. Bare, shining, with narrow band of tomentum on extreme lateral margins only. Male genitalia compact, with pointed lobes, rotated through about 90° anticlockwise. Female with rather long, slender acanthophorites.

Legs. No spurs on tibiae, and no other structural peculiarities. Femora and tibiae slightly swollen in one species, less so in other.

Wings. Of primitive shape : i.e. broad, with costal cell broad, and all cells open on wing- margin, including anal.

Dogonia saegeri sp. n.

(Text-figs 42-44)

A rather small species, with dark head, thorax and wings, red abdomen and legs. It differs from the following species, D. nigra sp. n. in coloration and in the male genitalia. (Text-figs 41, 43).

270 H. OLDROYD

(J Head. Black. Frons and face with dense yellowish tomentum. Frons with multiple row of bristly hairs along eye-margins, and another row leading from each antenna to ocellar tubercle : mostly pale yellowish, a few brownish or black ; ocellar tubercle with two or three pairs, some black. Face similar, but with no hairs dorsal to facial tubercle ; all hairs and bristles concentrated into a moustache, which is confined to facial tubercle, and almost entirely pale yellowish or white, with only one or two black ones. Palpi black with black hairs. Proboscis black or mahogany-red, with yellow hairs. Antennae black, with pale yellowish hairs. Occiput black with whitish tomentum and silky whitish hairs, no strong bristles.

Thorax. Ground colour black with some reddish areas, notably humeri, postalar calli and posterior parts of pleura. Covered with brown tomentum, yellow laterally. Pronotum with long, fine yellowish hairs, and no strong bristles. Mesonotum clothed uniformly and fairly densely with black hairs, which are slightly longer than first antennal segment. Scutellum with no true apical bristles ; with fine discal bristles and a submarginal row of 6-8 longer, erect. Pleura patchily black and red, covered with dense yellowish tomentum except for a large area of shining black on mesopleuron. Pleural tufts of hairs pale yellowish, except those before halteres, which may be partly black.

Abdomen bright orange : dorsum bare and shining, except for a narrow strip of whitish tomentum along each side. Face black, rather long, clothing hairs distributed over entire dorsum. Male genitalia (Text-fig. 43) red with black tips, and with long black hairs.

Legs. Coxae like pleura, with whitish hairs. Rest of legs mahogany-brown or irregularly blackish, with black bristles, and clothing hairs that are uniformly whitish. Pulvilli light brown ; claws black, reddish at base.

Dogonia nigra sp. n.

(Text-fig. 41)

Distinguished from D. saegeri by its black colour, and by the different shape of the male terminalia (Text-figs 41, 43).

<J Head black, with dense white tomentum, a little brownish on vertex. Bristles a little stronger, perhaps, than in saegeri, in some rows on frons, along eye-margins, and from antennae to ocelli ; mostly pale yellowish, but with isolated black ones. Moustache confined to facial knob, composed of white bristles with a single black one at each side. Palpi and proboscis black with yellow-brown and black hairs. First antennal segment black, second and third dark reddish ; first two segments with yellowish hairs. Occiput with white tomentum and silky white hairs.

Thorax. Pronotum speckled brown-grey, with fine, pale yellowish hairs. Mesonotum with thick tomentum, black-brown in two longitudinal stripes and paired lateral spots, yellowish in between ; entirely clothed with rather long black, bristly hairs, individually spaced, and hardly to be distinguished from the thicker bristles. Scutellum ashy dark grey, with sparse, curved clothing hairs, and with 4-6 submarginal bristles, curved upwards, and the middle pair even crossed. Pleura black, with ashy yellowish grey tomentum, leaving bare a large, shining black patch on mesopleuron. Hairs mostly pale, but with some black bristly hairs on mesopleuron.

Abdomen. Dorsum shining black-brown ; entire first segment, side-margins of rest, and a narrow hind margin of seventh tergite with grey tomentum. Venter shining black-brown.

Elasmocera Rondani, 1845 : 153. Type-species : Elasmocera cingulata Rondani, 1845, mono- typic.

This distinctive genus is easily recognized by the most peculiar shape of the proboscis (Text-figs 44-48), short, pointed, backwardly curved, and when seen in profile, resembling a comma, or a parrot's beak. The genus occurs in the Palaearctic, Ethiopian and Oriental Regions, and is remarkably constant in general characters which, except for the proboscis, are close to those of Scylaticus (q.v.).

It seems evident that the characteristic proboscis must be related to some peculiarity of diet, but as far as I know no-one has attempted to speculate what it might feed upon. Some observations on this proboscis will be the subject of a separate small paper.

At least 22 species of Ancylorrhynchus exist in the Ethiopian Region, but only A . crux Bezzi is recorded from the Congo Basin, and that from an unknown locality. The collections from the P. N. du Garamba contain no Ancylorrhynchus ; M. Fran9ois collected A . crux and an undescribed species from Urundi.

Ancylorrhynchus striatus sp. n.

One of the rather few species of Ancylorrhynchus to have bicoloured legs, this species is distinct from all others in having a narrow black longitudinal stripe on all the femora, which are otherwise red.

$ Head in ground colour black, covered with dense yellow tomentum, leaving only a small bare spot beneath the antennae, and one on each side of mouth-margin. Hairs of frons and face pale yellow, including a shallow moustache on mouth-margin, linked with tracts of longer hairs on each side of face. Hairs and bristles of occiput and beard, in contrast, deep red, bristles strong and dense. Antennae red, third segment with blackish stripes, first two segments with yellow hairs and bristles. Palpi reddish with black bristles. Proboscis red.

Thorax. Pronotum red anteriorly, black posteriorly and laterally. Mesonotum red, with usual cruciform black markings, its transepts triangular, and a distinct brown median line ; behind each humerus a barrow black crescent ; scutellum red with a transverse black basal band ; bristles yellow, 4 notopleurals, 3 postalars. Entire dorsum covered with a white, powdery dusting, which greatly obscures the pattern. Pleura entirely black with brown tomentum, except for a reddish area beneath hind spiracles and halteres.

Abdomen. First six segments black, each becoming more reddish posteriorly, and with a narrow red hind margin. Thick brown or yellowish brown tomentum, and numerous pale yellow clothing hairs, but no strong bristles. Last two segments and terminalia orange, with orange spines.

Legs. Coxae like pleura. Legs otherwise red, femora each with a narrow black stripe along dorsal surface. Bristles yellow, becoming black on fore tibiae.

Wing. All cells open on margin, including anal (narrowly). From anterior cross-vein to wing- tip is brown, and a further brown band runs across base of discal cell. Halteres bright yellow.

Length of body 16 mm ; of wing 12 mm.

SCYLATICUS Loew

Scylaticus Loew, 1858 : 346, 349. Type-species : Scylaticus zonatus Loew, by designation of Engel, 1929 : 369.

A genus of distinctive flies, bristly, with rounded head and inflated occiput. Obviously closely related to Ancylorrhynchus, but having a straight, acute proboscis of normal type instead of the characteristic beak-like proboscis of Ancylorrhynchus. The third antennal segment, too, is different.

Scylaticus is a genus of rather arid places, and in the Ethiopian Region the species are known from South Africa as far north as Nyasaland. Other species occur in

ASILIDAE OF THE CONGO BASIN 275

the Sahara and the eastern Mediterranean, as well as in India and in S. America. It seems likely that the two populations in North and South Africa may be linked through Kenya and Tanzania.

There are no specimens of Scylaticus in the collections from the P. N. du Garamba, and only three specimens, all different, from the Katanga. These will be left for future consideration, along with the S. African species. Engel (1932 : 276) pub- lished a key to those species known to him.

GONIOSCELIS Schiner

Gonioscelis Schiner, 1866 : 670. Type-species : Dasypogon hispidus Wiedemann, 1819, by original designation.

A very distinctive genus, generally resembling a small Stenopogon but recognized at once, in both sexes, by the characteristic development of the fore femora (Text-fig. 49). This is obviously a highly efficient apparatus for seizing and holding prey. The proboscis, though short, is stiff, acutely pointed, and slightly curved. The eyes are close together, as in Stenopogon, and there is the same dusty, bristly appearance and sandy colouring, appropriate to hunting in scrubby, arid areas.

There are no Gonioscelis in the collection from the P. N. du Garamba, but species occur in Urundi and in the Congo Basin.

Gonioscelis occipitalis sp. n.

(Text-fig. 49)

A red-legged species, with dull ashy grey-brown abdomen, distinguished from related species by the white-tomented occiput, with black triangles and entirely black, proclinate bristles.

$ Head. Even more strongly compressed than is usual in this genus, irons and upper part of face forming a parallel-sided strip scarcely broader than the two antennae together. Frons black, with bronze tomentum, and with proclinate hairs on each side, just above antennae. Upper part of face, above facial hump, similar, with a band of strong black bristles medially ; facial hump only moderately prominent, covered with white tomentum except at extreme lower angles, where there is a bare, black spot on each side. Moustache mainly of strong black bristles, with white ones on mouth-margin. Occiput covered with white tomentum, except for a pair of large, shining black, bare triangles just behind vertex. From these triangles arise very strong, proclinate, black bristles, with finer black bristles surrounding them, and a single row of straight black bristles parallel to eye-margin, but some distance behind it. Beard yellowish white ; palpi and proboscis black with black and white hairs. Antennae with first two seg- ments blackish with black hairs (rest missing).

Marginal scutellars black, one strong pair and one weaker. Pleura with no strong hairs or bristles.

Abdomen dully shining black-brown through thin ashy grey tomentum, and covered with short, stiff black bristles, with longer tufts at sides of first and second segments. Segments 7, 8 shining reddish brown and forming part of ovipositor. Venter similar.

Legs. Coxae like pleura. Fore and middle coxae with strong white bristles, third with a few black bristles. Fore femora black basally on anterior surface ; mid femora a little so ; legs otherwise reddish yellow, even to tips of tarsi. Short clothing hairs white, bristles black.

Gonioscelis tomentosus sp. n.

A black, dark-winged species, in general appearance resembling only G. nigripennh Ricardo, but distinguished from that species by having the thorax not shining black, but covered with tomentum, that of the pleura especially being dull bronze. From G. lacertosus Engel, which also has dark wings, G. tomentosus is distinguished by the leg-colour, the legs of lacertosus being almost entirely orange.

Gonioscelis congoensis sp. n.

(Text-figs soa, 5ob)

This species is described, in spite of the poor condition of the available material, because it is confusingly close to genitalis Ricardo, from South Africa. The two species may be distinguished by the male genitalia (Text-figs 5oa, 5ob).

cJ Head. Frons and face very narrow, hardly diverging towards mouth-margin. Ground colour black, covered with tawny tomentum and tawny hairs and bristles. Ocellar tubercle with a few black bristles.

Occiput with yellow tomentum and two large, diamond -shaped, shining black patches (cf. occipitalis sp. n.) ; occipital bristles mixed black and yellow, a multi- serial row some distance behind eye-margin. Antennae, proboscis and palpi black, with black hairs.

Thorax black with brassy yellow tomentum. Mesonotum without pattern, though with faint indications of a median stripe. Covered with very short black bristles ; 5 pairs of long, strong black supra-alars ; a notopleural supra-alar row of 4-5 black ; 2 postalars, yellow or black.

RHABDOGASTER Loew

Rhabdogaster Loew, 1858 : 346, 351 ; Engel, 1929 : 168. Type-species : Rhabdogaster nudus Loew, monotypic.

Described both by Loew and by Engel as resembling a Leptogaster, but with complete pulvilli, and with acanthophorites in the female. The male genitalia are of a rather distinctive structure, with the epandrium divided into two large lobes, and with long, curved aedeagus (Text-fig. 52). Posterior to the hind coxae, beneath the base of the abdomen, is a heavily sclerotized arch instead of the usual membranous area : according to Hull's key (1962 : 119) this character distinguishes Rhabdogaster from related genera.

Two of the known species of Rhabdogaster — nudus Loew (1858) and maculipennis Engel (1929) — are both small or very small (7-8 mm), delicate flies, pale yellow in colour. The new species is larger than this (10 mm), and shining black, and so is close to nitidus Hull (1967), from S.W. Africa, which I have not seen.

$ Head in front view relatively broad, but not as broad as that of Xenomyza : breadth of frons : height of frons + face = 2:1 instead of 2-5 : i. Frons and face parallel-sided, more than half as broad as an eye ; shining black in ground colour, with sparse yellow tomentum. Face has no perceptible facial knob, but a moustache of sparse white hairs occupies basal half, and is surmounted by very short, scaly yellow hairs which reach up to antennae. Hairs and weak bristles on ocellar tubercle, vertex and occiput, all white or pale yellowish. Proboscis

ASILIDAE OF THE CONGO BASIN 281

and palpi black, with whitish hairs. Antennae black, with yellow hairs, third segment slender, pointed, as long as first two together ; style almost two-thirds as long as third segment.

Thorax. Mesonotum shining black, with only small areas of yellow tomentum, of which humeral triangles are the most conspicuous ; a narrow line of tomentum in suture at base of scutellum, and at extreme lateral margins of mesonotum. Extremely short, fine yellow hairs along lines of acrostichals and dorsocentrals, and on transverse suture. Two strong noto- pleurals, a cluster of four or five prescutellars, but no marginal scutellars. Scutellum shining black, rather convex, with a deep submarginal groove. Pleura also shining black with very thin white tomentum : tufts of white hairs on pronotum, propleuron, upper sternopleuron and before halteres.

Abdomen elongate, cylindrical, much longer than wings, which reach only to tip of fifth segment. First five segments bare, shining black ; sixth-eighth segments with dark brown tomentum ; all tergites with short black hairs. Venter with pale yellowish tomentum and whitish hairs. Genitalia as in Text-fig. 52, prominent.

Legs predominantly black, but knees and hind tibiae and metatarsi red or reddish, especially posteriorly. Hairs and bristles of legs almost entirely white.

Wings. Venation simple : anal cell closed, with short stalk, but all other cells open on wing- margin ; discal cell long and narrow, its origin almost as far back as fork of RI/RZ+S. Veins brown or black. Membrane clear and apparently colourless, but with microtrichiae scattered over most of area except basally. Halteres orange.

Length of body 10 mm ; of wing 7 mm.

Tribe STICHOPOGONINI

This is a small tribe of interesting Asilidae, set apart from Saropogonini by having the prosternum complete, or nearly so, and firmly bridged to the propleuron. The female terminalia are characteristic (Text-figs 54, 55), with the eighth sternite produced like the hull of a boat, and often with a distinct keel, surmounted by a crown of spines, and sometimes terminated with a dense brush of silky hairs. Though some Saropogonini have a similar structure it is not so fully developed.

The most obvious characteristic of this tribe is the saddle-shaped excavation of the vertex, as a result of which the eyes are much more widely separated at the vertex than opposite the antennae (Text-figs 53, 56, 57, 60).

Hull (1962 : 104) recognizes thirteen genera in this tribe, including Eremodromus Zimin and Turkmenomyia Paramonov, which were unknown to Hull, and omitted from his key. Lasiopogon, though apparently correctly assigned to this tribe, stands apart from the rest, and is a genus of Holarctic robber-flies that hunt in grassy areas from shrubs and low herbage. The rest of the tribe are essentially xerophilous, and are to be found sitting in full sunlight on sand, or on the stones of a dry stream-bed. For concealment they rely on their cryptic grey colouration and on the dazzling effect of the light. They sit motionless until potential prey flies overhead, and it may be that the characteristic broadening of the frons and separation of the eyes at the vertex is a device to improve stereoscopic vision directly overhead.

282

H. OLDROYD

Apart from Lasiopogon, the other genera are basically very much alike, and should perhaps be reduced to subgenera of Stichopogon. The differences are small details of antennal structure, of the arrangement of the moustache, of the wing- venation, and of the presence or absence of pulvilli. The last character is somewhat elusive outside the tribe Leptogasterinae, occurring sporadically, and perhaps not even of generic significance ; for instance in the genus Glyphotriclis.

Though especially characteristic of arid areas, Stichopogon occurs throughout all the tropical and warm-temperate countries of the world, and is often found in stream-beds in well-watered country. In such areas, however, the number of species appears to be small, and individual species have a wide, if scattered, dis- tribution.

Hull (1962) records seven species from the Ethiopian Region. Of these Dasypogon dilutus Walker was removed to Stenopogon by Miss Ricardo ; 5. grossus from the Durban Bluffs is clearly a Clinopogon, and is possibly a synonym of C. nicobarensis Schiner, widely distributed round the shores and islands of the Indian Ocean. The remaining five species may be separated as follows:

Tribe XENOMYZINI

These are the ' goggle-eyed ' flies referred to in the Introduction, distinguished to the naked eye by the reduction of frons and face, and antero-posteral flattening of the head into a disc in which the eyes are large and prominent.

These features differ only in degree from conditions in many other genera of Asilidae, and are sometimes difficult to assess : it is generally easy to say when flies are ' goggle-eyed ', but not so easy to be certain when they are not. In the Ethiopian Region the prosternum is fully bridged to the pronotum in Xenomyzini, but this is not necessarily true in other Regions.

My key to genera (Oldroyd, 1963 : 7) recognized eight genera in this tribe, but a later revision of the genus Rhipidocephala (Oldroyd, 1966) rejected Holcocephala as not African, and merged Margaritola and Paroxynoton into Rhipidocephala. This

XENOMYZA Wiedemann

Xenomyza Wiedemann, 1817 : 60. Type-species : Damalis planiceps Fabricius, 1805, by

designation of Coquillet, 1910. Damalis auctt. nee Fabricius, 1805 : 147.

The name of this genus is usually Damalis, but the original concept of Damalis confused Asilids and Empids, and Westwood, 1835 designated as type of Damalis the first species, D. curvipes Fabr., which is an Empid. I therefore follow the example of Carrera, and use Wiedemann's name Xenomyza for this genus in Asilidae.

The species that have been described from Africa are nearly all from Southern Africa, and none of them appear to conform with any of the four species recognized below, which are all therefore described as new. The four are easily separated on genital characters as well as by colour differences, though, as I explain under the specific description, it is probable that specimens I have included in taciturna sp. n. should be separated into more than one species.

Xenomyza taciturna sp. n.

(Text-figs 61, 62)

A variable species, by far the most numerous in the present collections, and showing a considerable range of size and colour. It may be that more than one species is confused here, but the characteristic male genitalia vary between the two types shown in Text-figs 61, 62, without any constant differences.

o* Head. Ground colour brown, covered with brown tomentum ; frons entirely tomented, except for ocellar tubercle ; face mostly bare and shining brown except for upper third. Vertex with long and fairly dense black hairs. Face with very sparse brown hairs and a moustache consisting of only 5-6 black bristles in a single row. Antennae black-brown with black hairs. Proboscis and palpi black-brown but with pale hairs. Occiput with grey tomentum and white bristles.

Thorax brown, entirely covered with tomentum except for edges of humeri and of postalar calli. Tomentum of mesonotum whitish, with a pattern of three stripes in brown. Scutellum covered with whitish tomentum. Pleura with grey tomentum and a dense tuft of yellow hairs on metapleuron ; other pleura with only sparse yellowish hairs.

Abdomen black-brown in ground colour, covered uniformly with yellowish grey tomentum except for a transverse band basally on second segment. Hairs sparse, yellowish, but not noticeably longer laterally. Venter similar. <$ genitalia as in Text-figs 61, 62, shining red- brown, contrasting with dull, blackish abdomen.

Legs clear mahogany-brown with rather long, yellowish clothing hairs, and a few fine black bristles. Hind femora as in Text-fig. 66.

Wings clear, colourless. Halteres yellow, including knob.

Length of body 8 mm ; of wing 7 mm.

This species shows considerable variation in size and colour, partly arising from differences in the age and state of preservation of the specimens, but with un- usually large variations even after allowing for these factors. This is particularly true of the specimens in the collection of the Muse'e R. de 1'Afrique centrale, many of which are considerably bigger and more yellow than the specimens from the P.N.G. For the present I provisionally identify all specimens with the male genitalia notched as in Text-figs 61, 62 as belonging to taciturna, but I feel sure that eventually it will be possible to set aside two, if not three species in this complex. The Congo specimens include a good series from Kifumashi (most nearly resembling the typical series from P.N.G.) ; Kapanga ; Mayumbe ; Stanleyville ; Elisabethville and Mayidi. I do not list these doubtful specimens as paratypes.

Xenomyza poseidon sp. n.

(Text-figs 64, 66)

A brilliant little species, with most of mesonotum and legs shining black. It has hind femora like those of scutellata sp. n., but has the colour-differences shown in the key.

c£ Head shining black in ground colour, with dense pale yellow tomentum, which leaves certain clearly denned areas bare, shining black : a narrow triangle surrounding ocellar tubercle ; a transverse line through bases of antennae ; lower third of face, underlying all swollen facial tubercle. Moustache consisting of 4-6 isolated black bristles ; short hairs pale, present only at vertex and on parafacial areas. Antennae black, third segment and apex of second more mahogany-brown, apical half of arista white ; first two segments with black hairs, third segment elongate, tapering. Palpi black with black bristles ; antennae black-brown with yellow hairs. Occiput entirely tomented grey, with a single row of light yellowish occipital bristles.

Thorax shining black, with dense yellowish white tomentum, which leaves certain areas bare and shining black ; mesonotum with a broad, divided, median stripe, flanked by the usual double spot on each side, but all stripes end abruptly opposite wing-bases. Scutellum covered with tomentum except for a very narrow black rim. Numerous very short black bristles in clusters, especially thick on upper supra-alar area. Pleura similarly covered with tomentum,

but without short spines, leaving bare two large areas, one on mesopleuron and one immediately behind it, on pteropleuron. Pronotum, propleuron and metapleuron with fine pale yellowish hairs. No marginal scutellar bristles are visible.

Abdomen without a constriction (cf. amphora sp. n.), but second segment distinctly grooved transversely. Abdomen, like thorax, black in ground colour, with areas of white tomentum anteriorly and laterally on each segment (only laterally on second segment), and with areas of short spines posteriorly and laterally on all segments. Venter shining black with posterior tomentum on each segment, and with short yellowish hairs. Genitalia as in Text-fig. 64.

Legs black, middle and hind tibiae orange, darker at tip. Hind femora as in Text-fig. 66, swollen along whole length, and with a double row of strong black spines ventrally. Other femora less swollen, and with only isolated spines. Bristles and most hairs black, but many clothing hairs yellow.

Wings almost uniformly brown, alula a little paler. Halteres orange including knob.

Length of body 10 mm ; of wing 9 mm.

Xenomyza scutellata sp. n.

(Text-fig. 67)

Shares with poseidon sp. n. the uniformly swollen hind femora, with double row of ventral spines, but instead of being shining black, the entire legs are honey- brown, with long, recumbent clothing hairs ; differs also in having the mesonotum more tomented but the scutellum, in contrast, bare, shining brown.

<J Head black-brown, covered with dense brown tomentum, frons and face with no clearly defined bare areas. Venter with a small number of long, black hairs : frons without long hairs ; face covered with rather long, pale yellow hairs, which are reclinate, and grow upwards along face. Moustache consists of a double row of yellow bristles on mouth-margin. Antennae black : first segment with a long, black bristle ; second with a shorter brown one ; aristiform extension long, white apically. Proboscis and palpi black with yellow hairs.

Thorax shining black in ground colour, entirely covered with tomentum, but in preserved

specimens this may be rubbed away in irregular areas. Tomentum is bronze, more yellow towards sides and posteriorly : in contrast, humeri, posterior calli and scutellum are all bare, shining brown. Yellow bristles, though fine, are relatively strong for the genus Xenomyza, and follow lines of dorso-centrals and acrostichals, as well as clustering laterally. Scutellum with 5-6 quite strong yellow marginals. Pleura covered with tomentum, yellowish, partly brownish, and with unusually abundant pale yellow hairs on pro-, meso- and metapleura.

Abdomen shining black in ground colour, with bronze tomentum. First segment with well- developed transverse membranous area, posteriorly bare and shining ; other segments only irregularly shining where rubbed. Almost bare of hairs on disc, but tufts of longer yellowish hairs laterally ; ventrally with whitish tomentum and pale yellowish hairs. Genitalia as in Text-fig. 67.

Legs honey-brown, femora and tarsi rather darker than tibiae. Hind legs noticeably long and thick compared with those of fore and middle legs ; hind femora strongly and uniformly swollen, with a double row of short, black spines ventrally. Otherwise legs mostly covered with rather long yellow bristles and long, recumbent yellow clothing hairs ; only tarsi with substantial numbers of black bristles.

Wings smoky black-brown, more intensively so anteriorly. Halteres yellow with whitish knob.

OLIGOPOGON Loew

Oligopogon Loew, 1847 : 497. Type-species: O. hybotinus Loew, monotypic.

This is a strange, small genus, which has attributes of both Stichopogonini and Xenomyzini. The female genitalia closely resemble those of Stichopogon (Text-fig. 68), but the head is quite unlike the characteristic saddle-shaped vertex and scaly moustache of the Stichopogonini. Instead, it is goggle-eyed, with a fringed antennal style, and is much like Rhipidocephala of the Xenomyzini. In fact, Oligopogon looks like a head and thorax of Xenomyza, with an abdomen of Stichopogon and legs of a Saropogonine genus such as Holopogon. Engel (1929 : 372) says that Oligopogon has strong discal bristles on the abdomen, and in his key he gives these as a means of separating Oligopogon from Rhipidocephala, but there are no such bristles in any specimen that I have seen.

One constant character of Oligopogon is the small size of the discal cell (Text-fig. 69), a feature which excludes 0. atrum Bigot from the genus.

The type-species, 0. hybotinus Loew, was described from the island of Rhodes,

69

ASILIDAE OF THE CONGO BASIN 295

and this was the only Palaearctic record known to Engel (1929 : 372) ; the BMNH has one female of hybotinus from Turkey. Efflatoun (1937 : 290) described a dis- tinct species nitidus from the Red Sea coast (Gebel Elba), which forms a link be- tween the Palaearctic hybotinus and the other species of Oligopogon in the Ethiopian Region.

In 1858 Loew extended Oligopogon to the Ethiopian Region by describing 0. penicillatus from Caffraria. Engel (1932) added 0. pollinosus from Rhodesia, and Engel & Cuthbertson (1937) described 0. nigripennis from the Vumba Mountains of S. Rhodesia. 0. nigripennis, with its dark wings and rather robust appearance sounds as if it might, in fact, be a Rhipidocephala, but I have seen no specimen of it, and include it in the key from the description, for the sake of completeness.

Finally, Rhipidocephala hyalipennis Oldroyd (1959), from Madagascar, is properly an Oligopogon. It seems, therefore, that Oligopogon extends from the eastern Mediterranean down to the Cape, and it is not surprising that the present collections should include a new species from the Katanga, as well as a series of specimens from Urundi that I am unable to separate from the Palaearctic hybotinus Loew.

The following key includes all the species of Oligopogon at present known to me, but these small, obscure flies easily escape notice, and it is very likely that other species will subsequently be discovered.

Oligopogon harlequini sp. n.

Distinguished from all the other species of Oligopogon by the conspicuous orange and black bands of the antennae and legs.

o" Head. Eyes in dried specimens often rusty brown with distinct and symmetrical black spots. Face and frons almost parallel-sided, about two-thirds as broad as one eye ; black- brown, covered with dense brassy tomentum. Ocellar tubercle large, also covered with brassy tomentum, but with one pair of long, black, ocellar bristles, and several smaller pairs. Frons with fine, inconspicuous short brown hairs ; moustache covering lower half of face, but rather sparse, with a few stronger bristles, and a number of fine bristles, all yellow. First two antennal segments black, with brassy tomentum and yellow hairs ; third segment orange on basal two- thirds, black on apical third ; first segments of style yellow, bare ; second segment of style black with black hairs. Proboscis and palpi black with yellow hairs. Occipital bristles in a single row, longer and black dorsally, shorter and yellow ventrally. No distinct beard.

Thorax densely covered with brassy tomentum, with an unusual arrangement of bare, shining black spots, all in posterior half of mesonotum : a short median stripe, flanked by crescentic spots extending into supra-alar area, and a small spot on each side just in front of suture ; postalar calli partly bare ; two small spots of brown tomentum anteriorly ; scutellum bare posteriorly, tomented anteriorly. Mesonotum clothed with short, erect, fine hairs, black anteriorly and medially, yellow posteriorly and laterally ; two strong, yellow notopleural bristles, otherwise no strong bristles, even on scutellum. Pleura, including postscutellum, entirely covered with brassy yellow tomentum, with fine yellow hairs on mesonotum, and bristly yellow hairs in mesopleural fringe.

Abdomen mostly shining. Dorsally each segment brown anteriorly, black posteriorly, the proportion of black greatest on basal segments, and least towards tip of abdomen. Third to sixth segments also with a narrow basal band of white tomentum, which extends along extreme lateral margin. Hairs fine, yellow, semi-recumbent. Venter mostly light brown, with thin white tomentum, and each segment with a pair of large, bare spots. Male terminalia black or brown, with yellow hairs.

Legs yellow-brown, with distinct black bands : each femur has a broad preapical band, and each tibia a prominent black tip.

Wings clear, hyaline, no grey patches. Halteres orange.

0. hybotinus was described from the island of Rhodes in the Eastern Mediterranean, and has hitherto not been known from anywhere else. In the BMNH is a female specimen from TURKEY : Antalya, Kaldivar nr Gasipazo, c. 750', 2O-22.vii.i963 (E. James). I have no doubt that the specimen from Turkey is correctly identified as hybotinus, but I am not satisfied that the examples from Urundi are really con- specific. It is not possible to decide finally until male specimens of hybotinus from the Palaearctic Region are available to me.

Oligopogon superciliatus sp. n.

Somewhat resembling 0. penicillatus Loew, but distinguished by the excessively long rays of the antennal style, which are as long as the entire third antennal seg- ment, and by the strong contrast between the orange tibiae and tarsi and the black femora, orange only at base and tip.

$ Head. Frons and face covered with dense yellow tomentum, rather long, and divided by a vertical median line on the frons. Two long, strong, black ocellar bristles, other hairs of frons weak and yellow. Moustache of sparse but strong black or blackish bristles. Antennae notable for the excessive length of the cilia of the style : all segments brownish, covered with yellowish tomentum, basal segments with black hairs. Proboscis and palpi black with yellow hairs. Occipital hairs in a single row : black, longer and proclinate dorsally ; white, shorter and straighter ventrally.

Thorax entirely covered with yellowish grey tomentum, in which there are bare, shining black spots of irregular extent in posterior half of mesonotum. Postalar calli brownish, bare. Scutellum with white tomentum anteriorly, shining black posteriorly ; hairs fine, erect, black, no strong marginals. Pleura black-brown in ground colour, entirely covered with yellowish grey tomentum ; metapleuron with a vertical row of long, yellowish bristles, and a few long yellow hairs on sternopleuron, otherwise pleura without hairs.

Abdomen dorsally shining black, each segment with an anterior band of white tomentum, broken in middle into two spots, which are extended laterally as narrow white margins ; hairs of dorsum short, white on tomented areas, black elsewhere, longer and paler at sides. Venter black-brown with thin white tomentum and yellowish anterior margin to each segment.

Legs. Femora black, red at base and apex ; tibiae and tarsi orange, only indistinctly darker towards tips of tarsi. Many short yellow hairs, but longer hairs and bristles mainly black.

Wings clear, hyaline, veins yellow anteriorly, black posteriorly . Halteres pale yellow.

Length of body 6 mm ; of wing 5 mm.

Tribe ASILINI

This complex tribe of many genera is the most advanced in the family. It is characterized by the universal closure of the marginal cell, and by the third antennal segment ending not in a style, but in an arista, sometimes long, but always bare. The members of the tribe Ommatiini are distinguished from Asilini by having the antennal arista conspicuously feathered, but it is doubtful how much significance should be attached to this character (see under tribal heading Ommatiini).

Most Asilinae are elongate flies, with slender abdomen, and a generally dusty,

298 H. OLDROYD

appearance. The genera fall into various groups, of which one of the most distinc- tive is the Promachus-group.

4

The PROMACHUS-GROUP

Characterized by having three submarginal cells in the wing in place of the usual two. The significance of this in the evolution of Asilidae has already been discussed in the general part of this paper. The genera of this group have a rather curious distribution : Promachus itself occurs in every zoogeographical region, with a complexity of subgenera ; Apoclea is located in the middle eastern arid belt ; Philodicus and Alcimus are Indo-ethiopian ; and in central and tropical South America there is a small complex of bee-like genera centred round Mallophora. Apart from the distinctly bee-like habitus of the Mallophora subgroup, the principal distinctions are in the wing-venation. Although these differences seem trivial when described, they are remarkably constant, and they are reinforced by other differences in appearance which confirm that the genera of this group — or at least the prinicpal genera already mentioned — are really distinct.

PROMACHUS Loew

Trupanea Macquart, 1838 : 91, nee Schrank, 1803. Type-species : Asilus maculatus Fabricius,

by original designation. Promachus Loew, 1848 : 390. Type-species : Asilus maculatus Fabricius, by designation of

Coquillet, 1910.

A large and complex genus, which occurs in all the zoogeographical regions, and is easily recognized by the particular shape of the three submarginal cells.

Although distinctive at generic level, Promachus includes a great diversity of species. Hull (1962) recognizes six subgenera (not five as he says), but the status of these is uncertain. The subgeneric differences are mostly in the antennal arista and in the form of the ovipositor : the former is often variable between closely related species, and the latter appears to be an adaptive character, related to the site of oviposition, and thus not necessarily indicative of relationships.

The African species have never been revised in their entirety, as yet. Miss Ricardo (1920) published partial keys, but besides being incomplete they were ill- constructed and difficult to use. At the present time (1969) Mr. P. Blasdale, who revised the African species of Philodicus in 1957, has work in progress on the species of Promachus, and has kindly examined the species of Promachus taken in Garamba by the Mission H. De Saeger.

THE F^SC/^TC/5-GROUP

This is a striking group of species centred round Pro machus fasciatus (Fabricius), 1775, and recognized by having the first three tergites of the abdomen adorned with double fringes of white or golden hairs.

The present collection contains four females of this species-group. The males have distinctive genitalia, and may be identified by using an excellent paper by Hobby (1936 : 182-199, 231-249, 274-278). Unfortunately the females cannot be confidently identified, except by association with males, and so the females in this collection can only be listed, as follows :

302 H. OLDROYD

HELIGMONEURA Bigot Heligmoneura Bigot, 1858 : 357, 662. Type-species : H. modesta Bigot, monotypic.

Engel (1927 : 135) discussed the definition and relationships of this genus, and especially its distinction from Neomochthems, for which he presented a table. Heligmoneura is one of several genera in which the vein ^5 of the wing has a pro- nounced angle at mid-length ; it has pilose metanotal callosities, and a low facial hump, which becomes nasiform through the narrowing of the face. In the male the upper forceps (epandrium) is forked, and often conspicuously so (Text-figs 70-72). The ovipositor is short and downturned.

Seven species from Africa and Madagascar remain in Heligmoneura after making allowances for past confusion with other genera such as Neomochtherus and Neolophonotus. The present collection contains three species, only one of which is from the P.M. Garamba. The three species are easily separated by the very dis- tinctive male genitalia (Text-figs 70-72) ; a key to species using other characters, and applicable also to females, awaits a fuller study.

Heligmoneura laevis Engel

death ; Engel (1927) attributes the species to ' Hermann in litt.', but it appears that Engel was the author of the published description, and hence of the name.

The form of the male genitalia (Text-fig. 70) appears distinctive, but small variations occur, and it is possible that more than one species has male genitalia of this type. A particular problem is N eomochtherus litoralis Lindner (1955), which is annotated in the original paper ' Auch nach Oldroyd " not laevis Engel, probably new ". .' I saw the specimen afterwards made type of litoralis, which was from Dar-es-Salaam, but it is not now before me. From the description and figure it is certainly a Heligmoneura, not N eomochtherus, and very close to H. laevis. It appears to differ from laevis in having more pale hairs and bristles on the thorax, but clearly this needs to be corroborated by evidence from more specimens.

H. laevis was described from the Waterburg District of the Transvaal, and is known from Malawi. The present record of the species from the P.N. du Garamba extends the range considerably, with litoralis in Dar-es-Salaam as a possible link.

Heligmoneura rodhaini sp. n.

(Text-fig. 72)

A single male, abundantly distinguished from the preceding two species by the genitalia (Text-figs 70-72). The upper forceps are less deeply cleft than in those species, and suggest the even less elaborate male genitalia of H. africana Ricardo, from Nyasaland. This raises the question of the separation of Heligmoneura from N eomochtherus, readily apparent between typical species of each, but less certain when the genitalic differences are smaller.

CONGOMOCHTHERUS gen. n.

Type-species : Congomochtherus lobatus sp. n., by present designation.

The type-species bears a deceptive resemblance to Machimus hirsutus Ricardo, being generally black and grey, with distinctive reddish bands basally on the tibiae. M. hirsutus, however, is a true Machimus, with dorsocentral bristles extending forward of the transverse suture, and ovipositor flattened, bare, with free anal lamellae. Congomochtherus is distinguished by having the presutural dorsocentrals weak or absent, and by the spiny anal lamellae of the female (Text-fig. 73).

The male of Congomochtherus has an enlargement of the ninth sternite (hypan- drium), which is quite different from the sclerotized process of the eighth sternite which is found in many Machimus (Text-fig. 74). In Congomochtherus the ninth sternite bears a brush or pencil of stiff black hairs, and in the species lobatus the sternite is extended posteriorly as a rounded lobe, which is yellow and of mem- branous appearance.

Congomochtherus is clearly allied to Machimus in facial and general structure ; the genitalia somewhat resemble those of Neomochtherus, which also has no pre- sutural dorsocentrals, but the spiny lamellae of the ovipositor have no counterpart except in genera such as Alcimus and Proctacanthus, which are not close related to Neomochtherus and Machimus. Vein R$ is distinctly angled in the middle, and the metanotal lobes bristly.

Congomochtherus penicillatus (Speiser)5

Machimus penicillatus Speiser, 1910 : 100.

Distinguished from lobatus by the male genitalia and the leg-colouring. Ninth sternite well developed, and with a tuft of black bristles (as in Text-fig. 74), but lacking the yellow median lobe. Legs black with reddish rings at bases of tibiae, and at bases of femora as well.

This species bears an extraordinary resemblance to Machimus hirsutus (Ricardo), the scanty and ill-preserved type-material of which was collected on the Mara River in Kenya by Capt. A. O. Luckman ; yet hirsutus has neither the spiny lamellae of the female nor the extended ninth sternite of the male.

HOPLOPHEROMERUS Becker

Hoplopheromerus Becker, 1925 : 241.

Tsacas and Oldroyd (1967) revised this genus, which has an interesting distribution in Africa and in the Far East. They described two new species from the Congo Basin, and discussed relationships with Heligmoneura and Neomochtherus.

5 While this paper was in the press, Dr. Tsacas has been kind enough to indicate to me certain specific differences between this species and one of the syntypes of Machimus penicillatus .Speiser which he has been able to examine. It is possible, therefore that future study of the syntypical series, with selection of a lectotype, may require a renaming of the species recorded above as penicillatus Speiser.

MACHIMUS Loew

Machimus Loew, 1849 : i. Type-species : Asilus chrysitis Meigen, 1820, by designation of

Coquillet, 1910. Tolmerus Loew, 1849 : 94. Type-species : Asilus pyragra Zeller, 1840, by designation of

Coquillet, 1910. Conosiphon Becker, 1923 : 36. Type-species : Dysmachus pauper Becker, 1907, by original

designation.

Typical Machimus has a distinctive structure, though no item of this is exclusive to this genus. Even the question whether or not the dorsocentral bristles extend ahead of the transverse suture is debatable : in typical Machimus there are one or two strong presutural dorsocentrals, but not as many as in Dysmachus.

The ovipositor of Machimus has the anal lamellae simple and free, not inserted into the ninth tergite as in Dysmachus, and not spiny as in Congomochtherus. In the male it is the eighth sternite that is prominent, not the ninth as in Congomocherus, and this sternite is often drawn out into a conspicuous process (Text-fig. 76) : con- versely, it may be without process (Text-fig. 77).

Machimus has the metanotal lobes of the thorax hairy or bristly, and vein R$ of the wing has a more or less conspicuous kink. These two characters separate Machimus clearly from the Neolophonotus-group of genera, as well as from Ommatius.

The species fall fairly easily into two groups : Machimus (sensu stricto) with a ventral process in the males, and with four or more scutellar bristles ; and those species that have no ventral process, and only a single pair of scutellar bristles. The latter may conveniently be referred to the subgenus Tolmerus, though a formal separation of the two subgenera is difficult.

The Machimus of the Ethiopian Region are mainly located in eastern tropical Africa, perhaps as an offshoot from the Palaearctic Region.

ASTOCHIA Becker

Astochia Becker, 1913 : 538. Type-species : Astochia metatarsata Becker, monotypic.

Typical specimens of Astochia are distinctive. The male genitalia are character- istically pendulant, with the upper forceps rather widely set apart from the lower forceps and claspers (Text -fig. 78). In the female the telescopic ovipositor incor- porates the seventh to ninth segments, as in Neoitamus. Typically, in both sexes, the anterior basitarsus is swollen and very bristly.

Astochia closely resembles Neoitamus which, typically, can be easily separated from Astochia by the proclinate postoccipital bristles, the different male terminalia, and the normally developed basitarsi. These differences are shown clearly by the

type-species of the two genera, Astochia metatarsata Becker of the Oriental Region, and Neoitamus cyanurus of the Palaearctic. The species of the Ethiopian Region do not fall so easily into the two genera, and the following assignments are provisional.

Astochia armata (Becker)

Neoitamus armatus Becker, 1910 : 22. Originally described from Voi, in KENYA.

GARAMBA NATIONAL PARK : P.N.G., 1461, II/fc/i8, 2 <j>, 28.iii.i95i ; 415, I/a/i, i $, 20.iii.i95o (IPNC).

Astochia strachani sp. n.

(Text-fig. 78)

Distinguished by the leg-pattern, and by the characteristic male genitalia (Text- fig. 78). All femora are black on anterior face and dorsally, with a red ring basally, which is absent in related species neavensis Ricardo and armatus Becker ; posterior and ventral faces of femora reddish yellow.

cJ Head. Black, obscured by thick tomentum. Tomentum of frons brassy, including ocellar tubercle ; 2 long ocellar bristles and 2-4 small ones, as well as vertical row along each eye- margin, all black. Face with more brownish white tomentum ; facial tubercle low but long, ending abruptly about as far below antennae as length of first segment. Moustache black above, but mostly white ; no other hairs on face. Occipital bristles very strong, black, one or two slightly proclinate at tip ; occipital hairs and beard white. Antennae black, with black hairs. Palpi and proboscis black, with white hairs.

FIG. 78. Astochia strachani, $ genitalia.

ASILIDAE OF THE CONGO BASIN 313

Thorax. Mesonotum entirely tomented : brownish grey, with the usual partially divided median stripes, reaching back to scutellum, and lateral stripes interrupted at transverse suture ; clothed with short, bristly black hairs, and strong, black bristles. Scutellum entirely grey, with white hairs, and two marginal black bristles. Pronotum brownish grey, with rather weak bristles, some of which are black, and with white hairs. Pleura grey, a little more brownish dorsally : bristles black in front of halteres, mostly yellowish elsewhere.

Abdomen. Dorsum grey, each segment with a median brown spot and a pair of lateral ones which become larger posteriorly. Clothing hairs mostly black and bristly, white ones laterally ; each segment laterally with one or more strong white discal bristles, and on first tergite with a tuft of white hairs and a row or cluster of bristles, usually black. Venter brownish grey, with whitish hairs and bristles.

Legs. Coxae like pleura, with yellow or whitish hairs and bristles. Femora reddish yellow, posteriorly and ventrally, black anteriorly and dorsally, leaving a narrow reddish ring at base.

by designation of Coquillet, 1910. Neoitamus Osten-Sacken, 1878 : 82, 235.

Comments have already been made, under Astochia, about the difficulty of separating the two genera Astochia and Neoitamus. The following species seems more likely than the others to be properly placed in Neoitamus.

Tribe OMMATIINI

Members of this tribe are characterized by the plumed antennae, which have a ventral fringe of long hairs on the arista (Text-figs 79-81). It might be doubted whether this single character is sufficient to define a tribe, but the few genera com- prised in Ommatiini are distinctive even when the antennae are broken. Hull

314 H. OLDROYD

(1962 : 433) regards the chitinized postmetacoxal arch as a tribal character. These genera have much in common with certain genera of Asilini, notably N ' eomochtherus and Heligmoneura, but recognition of Ommatiini as a tribe is convenient.

In the genus Ommatius Wiedemann the antennae are similar to those of Asilini, with short, seedlike third segment, but with the addition of a ventral fringe on the arista. Cophinopoda Hull, 1958 segregates a small group of species that are distri- buted from Madagascar eastwards to China and Queensland. Michotamia Macquart, 1838 (Allocotosia Schiner, 1866) comprises a number of Oriental and Australian species which are characteristically either yellow or purple in colour, and in which the third antennal segment itself is elongate, with correspondingly shorter, fringed arista (Text-fig. 80). A single species from the Congo, described in the present paper, seemed at first to be the only African representative of Michotamia, but it later proved to be a new genus Thallosia, differing from Michotamia in the genitalia (which resemble those of Cophinopoda), and in having antennae that are intermediate between those of Michotamia and those of Ommatius (Text-fig. 79).

The genus Ommatius is one of the most difficult genera of Asilidae, in spite of the complex genitalia of many of the species. About fifty species occur in Africa south of the Sahara, and what is known of their distribution suggests that some species at least may occur over a wide area. For these reasons the present report of this genus has been confined to the species of Ommatius that actually occur within the Pare National du Garamba, leaving the larger and more diversified collection of Ommatius from the rest of the Congo Basin to form part of a projected revision of the African species of Ommatius, to be made at a later date.

THALLOSIA gen. n.

Type-species : Thallosia congoicola sp. n., by present designation.

Differs from the varied assortment of species of Ommatius in the head structure as a whole. Antennae as in Text-fig. 79, with the third segment and arista about equal in length to each other, and to the first two segments combined. Face with a distinct but small tubercle, occupy- ing less than half of face, and bearing a sparse moustache of only a few strong bristles (Text-fig. 82). Occipital bristles strong, but few in number ; beard unusually sparse. Proboscis long, spade-like (i.e. dorsoventrally flattened) and arising from a stout base, which bears a small clump of strong bristles ventrally. Palpi cylindrical, with fine hairs.

Thorax with a strongly developed pronotum, with distinct 'collar'. Scutellum rather small, with a deep transverse furrow on its disc, and another immediately before scutellar suture. Male genitalia of the unique species remarkably like those of Cophinopoda, distinguished by the long, curved appendage to the upper forceps (epandrium) (Text-fig. 83).

Legs slender, without special features ; pulvilli square at tip as in Michotamia. Wings rather broadly rounded at tip. Vein R$ ending at, or shortly behind, wing-tip.

Thallosia congoicola sp. n.

(Text-figs 82, 83)

A mainly yellow species with distinctly patterned thorax. Male genitalia as in Text-fig. 83.

cj Head black in ground colour, vfrons with dark brown tomentum, including ocellar tubercle, but a small yellow patch just in front of this tubercle. Two black postocellar bristles, and a very few small frontal bristles, black. Face entirely covered with tomentum, which is whitish, a little brownish beneath antennae. Moustache confined to facial tubercle, consisting of only a few white hairs and bristles, and one or two black bristles dorsally. Extensive clypeal region (Text-fig. 82) bare, shining brown. Palpi cylindrical, shining black-brown, with yellowish hairs. Proboscis shining black, with a conspicuous clump of brown hairs ventrally near base. Antennae entirely yellow-brown with black bristles. Upper occiput with strong, moderately long, yellow bristles ; lower occiput with fine yellowish hairs, beard pale, unusually sparse.

Thorax entirely tomented. Mesonotum golden brown with a distinct pattern of darker brown, consisting of two widely separated longitudinal stripes, which end in middle of scutum and are succeeded by a single median stripe, and flanked by three well defined lateral spots. Scutellum yellowish brown, with sparse, stout yellow hairs but no marginal bristles. A few very strong black thoracic bristles : 2 notopleural, i supra-alar, i postalar, and one dorsocentral well ahead of scutellar suture ; only a few, sparse very fine black hairs aligned as dorsocentrals and acro- stichals. Pleura covered with yellow tomentum, but bare of hairs except for a strong ptero- pleural bristle and weak bristles ahead of halteres.

Abdomen dorsally reddish brown, without pattern, but more yellow basally, especially on second segment. Hairs black dorsally, yellow laterally ; hind margins of segments with longer, slender bristles, and laterally with at least one, quite strong, yellow bristle. Venter reddish yellow, with yellowish hairs. Male genitalia as in Text-fig. 83 ; upper forceps with long, curved process, recalling that found in Cophinopoda (Oldroyd, 1964).

Legs slender, entirely reddish yellow, except for slight darkening of last tarsal segment. Hind femora ventrally with a row of six short, black bristles.

Wings slightly and uniformly smoky. Marginal cell with a very short stalk ; stalk of fourth posterior cell long. Halteres reddish yellow.

Length of body 8 mm ; of wing 8 mm.

OMMATIUS Wiedemann

Ommatius Wiedemann, 1821 : 213. Type-species : Asilus marginellus Fabricius, 1781, by

designation of Coquillet, 1910. Ommatinus Becker, 1925 : 84. Type-species : Ommatius pinguis Wulp, 1872, by original

designation.

This genus originally contained only three species, marginellus Fabricius, auratus Fabricius and fulvidus Wiedemann. The two last have been removed to other genera, auratus to Michotamia and fulvidus to Cophinopoda. The type-species, marginellus, is one of a great range of tropical species of Ommatius which can only be resolved by a more detailed study. The following are merely the species taken by the Mission H. De Saeger in the P. N. du Garamba.

Ommatius vittatus Outran

(Text-figs 84, 85) Ommatius vittatus Curran, 1927 : 13.

There is a complex of species related to 0. variabilis Engel, and notable for the swollen hind femora of the males (Text-fig. 84). The exact number of species involved is obscure, but the present material clearly belongs to vittatus Curran, and should be known by that name until a study of the whole genus is possible.

A small, delicate species, with slender abdomen and yellow legs the male by the characteristic genitalia (Text-fig. 87).

$ Head. Eyes rather widely separated. Frons entirely covered with dark chocolate-brown tomentum, with several long, proclinate, black occipital bristles, and with long black hairs along eye-margins. Face with dense yellow tomentum, only slightly rounded in profile, without any distinct tubercle ; moustache with white or yellowish hairs and bristles near mouth-margin, and continued up to bases of antennae by a double row of black bristles, flanked with slender black hairs. Antennae black, with some black and some yellow hairs and bristles ; third segment short, little longer than first. Occipital bristles black and strongly proclinate ; lower occipital bristles and beard yellowish.

Thorax. Mesonotum entirely tomented, without definite pattern, though anteriorly and medially it is darker than postero-laterally. Thoracic bristles longer than usual, mostly yellow ; 2 notopleural, i supra-alar, sometimes one or two dorsocentrals ; fine hairs in positions of dorsocentrals, acrostichals, humeral and lateral areas are also exceptionally long and fine, longer than total of three antennal segments. Scutellum grey, with long, curved yellow hairs on disc, and several bristly yellow hairs, but no strong bristles, on margin. Pronotum and pleura grey, with entirely yellow hairs and bristles ; bristles are present on pronotal collar, and before halteres, and in a vertical row on posterior margin of mesopleuron.

Ommatius garambensis sp. n.

(Text-fig, go)

Apparently one of the vittatus-variabilis group of species, but distinguished from others by the male genitalia (Text-fig, go), with the square-tipped upper forceps, and by the colour of the femora, which are black with a dorsal or postero-dorsal reddish stripe.

(J Head. Frons and face relatively broad, narrowest at vertex, broadest at mouth-margin. Frons with brassy brown tomentum over a black ground ; ocellar tubercle shining black dorsally, with short black hairs on each side ; a single pair of black postocellar bristles on each side ; a single pair of black ocellars. Tomentum of frons paler, more yellowish ; facial tubercle occupying lower third of face, with a strong moustache of mainly black bristles, with white hairs and bristles on mouth-margin. Antennae black, with black hairs and bristles ; proboscis and palpi black with whitish hairs. Upper occipital bristles strong and black, lower occiput and beard with white hairs.

Ommatius caligula sp. n.

(Text-figs 91-93)

Superficially resembling digittatus sp. n., but distinguished in both sexes by the genitalia, and in the males by the arrangement of strong bristles on sternites 3, 4, 5 of the abdomen (Text-fig. 93). From drusus sp. n., both digittatus and caligula are distinguished by having the femora and tibiae entirely reddish yellow.

with fine, yellowish discal hairs, and two long, yellow, marginal bristles. Pleura with thin, golden brown tomentum on dorsal half and whitish tomentum ventrally. Hairs and bristles mostly yellowish ; a distinct pteropleural bristle, and a vertical row posteriorly on meso- pleuron, as well as before halteres.

Abdomen dorsally with dense brown tomentum, more greyish anteriorly, more reddish brown posteriorly, with fine yellow hairs becoming more bristly laterally, but without true bristles on tergites. Sternites 4, 5 bare, shining, others covered with tomentum. A remarkable arrange- ment of strong yellow bristles : a single pair on segment 2 and an arrangement on segments 3, 4, 5 as shown in Text-fig. 93.

Male genitalia very long, shining black, shaped as in Text-fig. 91.

Legs. Coxae like pleura, trochanters black. Femora entirely reddish yellow : fore femora ventrally with a row of about 4 powerful yellow bristles. Tibiae and basitarsi also reddish yellow, tarsi then becoming progressively darker.

Wings. Uniformly greyish, with a coating of microtrichiae. Halteres reddish brown.

Length of body 7 mm ; of wing 6 mm.

$ closely resembles male, except that ventral bristles on abdomen — evidently a secondary sexual character — are much less strongly developed. Female genitalia as in Text-fig. 92, eighth tergite strongly convex and overlapping sternite, giving this species a distinctive appearance.

ASILIDAE OF THE CONGO BASIN

0. canicoxa Speiser was described from the Kamerun, near Duala, and as far as can be decided from the description alone, it is represented in the BMNH by a small series from the Cameroons and Nigeria. The material agrees with Speiser's descrip- tion in the general colouring, and in particular in the wings, which are brownish antero-apically, and have the costal margin dilated, [die Ausbuchtung des Vorder- randes, welche vielen Ommatius- A.rten zukommt. . . .]

East African specimens resembling these were recorded by Oldroyd (1939 : 42) and by Lindner (1955 : 44), with a note of interrogation. Although there is con- siderable individual variation in chromatic characters as well as in size, it seems possible to distinguish two species by the dilation or not of the costal margin in the male, and in both sexes by the extent of the reddish base of the hind femora. Both species occur in the present collection ; those listed immediately above are the specimens believed to be true canicoxa, and the others, including Oldroyd's and Lindner's specimens, are referred to a new species, Ommatius drusus sp. n.

Ommatius sp. near canicoxa Speiser ; Oldroyd, 1939 : 41. Ommatius aff. canicoxa Speiser ; Lindner, 1955 : 44.

Closely similar to canicoxa Speiser, and with almost identical male genitalia (Text-figs 94, 95), but distinguished by not having the costal margin of the wing noticeably dilated, and usually by having the hind femora dimidiate, i.e. divided in the middle into a reddish yellow basal half, and a black apical half, with oblique border between the two colours.

H. OLDROYD

cJ Head. Frons narrower than in canicoxa, vertex less deeply excavated ; tomentum of frons light golden brown, ocellar tubercle shining black, prominent, and with two very strong black bristles ; hairs along eye-margins extremely small and inconspicuous ; face high and narrow, tomentum pale yellowish, moustache white on mouth-margin, extended towards antennae as two rows of black bristles. Antennae black, with black bristles ; third segment short. Pro- boscis and palpi black with yellow hairs. Upper occipital bristles black, proclinate ; lower occipital bristles and scanty beard whitish.

Scutellum with brassy yellow tomentum, weak and indistinct pale discal hairs, and one pair of black marginal bristles. Pronotum brownish medially, laterally pale yellowish like pleura ; pronotal collar of weak black bristles ; pleura with fine, pale, yellow hairs and stout black bristles, including a pteropleural bristle.

Abdomen. Dorsally cinereous, with dull reddish posterior margins to segments. Clothing hairs black, longer on hind margins, replaced laterally by yellowish hairs and one or more long marginals. Venter similar, with fine, yellow hairs. Male genitalia as in Text-fig. 95, black, but sometimes reddish.

Legs. Coxae somewhat yellowish in ground colour, with yellow hairs and bristles. Tro- chanters reddish. Femora reddish yellow with black markings : fore and middle femora black anterodorsally ; hind femora black apico-dorsally, with an oblique line of division between black and reddish areas (extent of colour varies, as well as distinctness of division between the two areas). Fore and middle tibiae and basitarsi reddish, with black tips ; a dorsal black stripe on tibiae and segments 2-5 of tarsi black. Hind tibiae reddish on basal half, blackish apically, tarsi blackish.

Wings. Costal margin not appreciably dilated ; sometimes only dark brown over a small stigmal area, otherwise mostly pale greyish as a result of microtrichiae which cover all cells except second basal. Halteres with yellowish stalk and deep red knob.

Length of body 10 mm ; of wing 9 mm.

UELE : Aba, i $, 2o.iv.i9i4 (Dr. Rodhain) (MRAC).

This species is very variable in the colour of the hind femora. It is provisionally identified with longipennis Lindner, though no information is given in Dr. Lindner's description about the genitalia. Confirmation of this identification must await a fuller study of the genus Ommatius in Africa.

Ommatius imperator Oldroyd

Ommatius imperator Oldroyd, 1939 : 45.

UELE : Bambesa, i <J, i 9. io.x.i933 (/. Leroy) (MRAC).

This species was described by me many years ago from specimens collected in Uganda by Neave and by T. H. E. Jackson. As far as I am aware, this is the first time that any other specimens have been noted, and so I record them in this paper.

0. imperator is perhaps the most striking species of the genus Ommatius, having the black body and yellow, black-tipped wings that are common to a whole complex of aposematic insects of various Orders.

ACKNOWLEDGEMENTS

I am deeply indebted to the late Dr. V. van Straelen for inviting me to study this most interesting material, and for originally agreeing to publish it, with the addition of other relevant material from the Congo Basin ; to Dr. P. Basilewsky for courteously allowing me to incorporate large collections of specimens from the collection of the Musee Royale de I'Afrique centrale, and to Monsieur F. J. Fran£ois and the authorities of the Institut R. des Sciences naturelles de Belgique for similar courtesies in respect of material collected in Urundi by Monsieur Fran£ois.

I am also indebted to Mr. Philip Blasdale for determining the specimens of Philodicus and Promachus and to Dr. L. Tsacas for advice about specimens of Neomochtherus, which he will incorporate into his own studies of that genus.

SYNOPSIS

In these lists, 171 taxa of Plecoptera and 74 taxa of Megaloptera are considered. Lectotypes are designated for 43 taxa of Plecoptera and 21 taxa of Megaloptera. The types of 8 other taxa of Plecoptera are either unlabelled and not recognizable from the descriptions, or have not been traced, being possibly in other collections.

INTRODUCTION

THIS list follows the general pattern of my previous Odonata Type Lists, but as the Plecoptera and Megaloptera are relatively small orders, I have not considered it necessary to present separate lists for the various families, all the taxa being dealt with alphabetically under the respective orders, and a combined list of references is given.

NOTES

1. The recognition of the individual types of the Plecoptera and Megaloptera described by Stephens presents some difficulties, since at some time since its presentation to the BMNH, the Stephens Collection was re-arranged by what McLachlan has described as a 'non-expert'. The specimens in most cases bore only a Stephens Collection label and were arranged over a small handwritten determination label. In few cases was there any indication of locality. During this re-arrange- ment, the various synonyms were placed together and the determination label placed on one of the series, with the result that it is almost impossible to differentiate the various type-series. In labelling types, the example bearing a determination label has been accepted as type, unless there is definite evidence to the contrary.

2. In the case of some of the Leptoperlid types from Australia, reference is made to the wings being mounted in de Faure's medium, a water-soluble mountant. This was recommended to me by the late Dr F. W. Edwards in the early j_94o's. It works quite well for wings and other very thin objects, particularly if the mounts are ringed with varnish. I found it however quite unsuitable for use with thicker mounts, such as whole Leptoperlids. Shrinkage of the medium in drying caused

air to be drawn in and these preparations had eventually to be dissolved in warm water, dehydrated and cleared and remounted in Canada balsam.

3. The Walker Type label is circular, bearing the word 'Type' and ringed with a green line. McLachlan's type label is small, rectangular, pink, red or purplish, bearing the word 'Type'.

Rules, 2nd edition). He gives St Martin's Falls, Albany River, Ontario as the type-locality, but there is no such indication on the specimen. Barnston's label gives the specific name as 'sonnans' , but the published name is 'sonans' ' .

350 D. E. KIMMINS

There is one paralectotype $.

The selection of a type-specimen for this species has been something of a problem, which has been made more difficult by the fact that Westwood himself did not publish a description of the species, Griffith's account being based upon notes supplied by Westwood.

The first description (1832 : 348) is very brief 'The body is dark brown, the upper wings pale, with a brown spot in each cell; the anterior margin purplish brown, and with a whitish fasciae rather beyond the centre: the hinder wings red, with a very broad bluish-black margin.'

The second description, by Newman (1839 : 33) is more detailed and agrees well with the two examples in BMNH determined by Westwood (and probably seen by Newman before they reached the BMNH). One was received from Westwood in exchange in 1841 and the other from the Entomological Club in 1844. The chief differences in the two descriptions are that Griffiths (1832) does not mention the conspicuous reddish streak along the radius in the fore wing, and the specimens do not show a pale fore wing with a brown spot in each cell. They are in fact brownish with a purple tinge, the cross-veins finely bordered with white. It is possible that Griffiths meant that the cells were almost entirely filled with brownish.

Tillyard based his interpretation of the species on these two examples, which were long ago labelled as syntypes, and I have therefore made the above lectotype selection, which is in conformity with current usage.

spio Newman (Chloroperla), 1839 : 86. Holotype <$. Sierra Leone / Chloroperla Spio Newman, Mag. Nat. Hist. n.s. Ill p. 86 [with on reverse], presented by the Revd. D. F. Morgan.

The locality 'Capel Curig' is in fact in the Welsh county of Caernarvonshire. Currently placed in the genus Isoperla.

suffusa Walker (Perla), 1852 : 154. LECTOTYPE $. Walker type label / Nepal, with on reverse 'Hardwicke Bequest' / Perla suffusa Walker, $ Lectotype, D. E. Kimmins det. 1969.

The type-series consists of two $ syntypes, both from Nepal. Walker's description agrees fairly well, although one venational character agrees only in one out of four fore wings. This is the number of cross-veins in the terminal areolet (space between costa and RI beyond the termination of Sc), which is said to be seven. The numbers are actually 4, 5, 5 and 7. I have selected as Lectotype the example which has seven cross-veins in the terminal areolet of one fore wing. The second example becomes a paralectotype.

Currently placed as the type-species of Brahmana Klapalek, 1916.

sulcicollis Stephens (Nemoura), 1836 : 143. Syntype [?sex]. Stephens Coll. / Nemoura sulcicollis Steph., D. E. Kimmins det. 1969.

In the Stephens Collection there is one example (now lacking abdomen) which agrees reasonably well with the original description, and although it does not carry a specific label from the Stephens Collection, I am prepared to accept it as at least one of the syntypes. Stephens' collection of Nemouridae was studied by Morton (1894 : 571) and sulcicollis was placed by him as a synonym of Nemoura cinerea Olivier, 1811. The latter is a homonym of Nemoura cinerea (Retzius, 1784) and Brinck (1949 : 37) has used the name Nemoura sulcicollis Stephens, 1836 as the first available synonym for Nemoura cinerea Olivier, 1811. Currently placed in the genus Amphinemura.

SYNOPSIS

The genus Macrotermes, including the genus Bellicositermes of some authors, is revised for the Ethiopian Zoogeographical Region. Of 23 species and n forms or varieties found in the literature, the varieties have not been retained ; ten specific names are found to be synonymous and three more are dubious. Since one variety has been given specific status and one species has been split into two, this leaves 12 recognized and redescribed species. M. ukuzii and M. mossambicus have been given specific status (the latter being a senior synonym of M. michaelseni) , M. falciger is another senior synonym (of M. goliath), M. natalensis has been split into M. bellicosus and M. natalensis, M. subhyalinus replaces M. bellicosus. Keys are given to the species ; notes are provided on their distribution and biology.

INTRODUCTION

AMONG the ten genera of the subfamily Macrotermitinae Kemner (1934), Macro- termes, like Microtermes and Odontotermes, occurs both in the Indo-malayan and the Ethiopian Zoogeographical Regions, the other genera being endemic to the Ethiopian

366 J. E. RUELLE

Region. One of the latter, Ancistrotermes, was recently revised (Harris, 1966) ; from the same region, 82 species of Odontotermes and 34 of Microtermes were recorded (Bouillon & Mathot, 1966). This paper deals with the African Macrotermes, which are represented by a very abundant material.

Smeathman (1781) described the first known species of this genus (Termes belli- cosus). Holmgren (1909, 1910) introduced the name Macrotermes as a subgenus of Termes. Various generic names were attributed to the Ethiopian Macrotermes from 1910 to 1926 (year of Sjostedt's last revision). The three genera recognized by Sjostedt, with 22 species altogether, were reduced in Snyder's catalogue (1949) to one (Macrotermes}, with 23 species. After 1949, two new species were described (M. angolensis, M. ivorensis) and two synonymized (M. convexus, M. jeanneli] .

Type-specimens, i.e. theholotype, lectotype, syntypes, paratypes or paralectotypes, where available, have been studied. One type-collection (M. ivorensis) has not been accessible ; three neotypes have been selected : M. bellicosus, M. subhyalinus and M. kibonotensis, the latter a junior synonym of M.falciger. In three cases (M. niger, M. gratus, M. ituriensis ; Sjostedt, 1898, 1900, 19240) the loss of the type-material and the impossibility of selecting a neotype leave the concerned species as nomina dubia. The words 'LECTOTYPE' and 'NEOTYPE' in capitals indicate designation in this paper.

MATERIAL

A total of 2,123 nest series from all parts of Africa have been examined, con- taining each from one to sometimes more than one hundred insects. The study started with the material of the British Museum (Natural History) (B.M.(N.H.)), much of which had been collected by the members of the Termite Research Unit. The following institutions have also been visited :

Muse'e Royal de 1'Afrique Centrale, Tervuren (Terv.) ; American Museum of Natural History, New York (A.M.N.H.) ; Institut Royal des Sciences Naturelles, Bruxelles (I.R.S.N.) ; Easier Museum, Abteilung Entomologie ; Museum National d'Histoire Naturelle, Paris.

Through the courtesy of specialists and others mentioned in the acknowledgements, types and other specimens have been borrowed from :

Naturhistoriska Riksmuseum, Stockholm (Stockh.) ; Zoologisches Museum, Berlin ; Zoologisches Staatsinstitut und Zoologisches Museum, Hamburg (Hamb.) ; Museum of Zoology, Cambridge ; National Collection of Isoptera, Plant Protection Research Institute, Pretoria (N.C.I.) ; Museu do Dundo, Lunda, Angola (Dundo) ; Lamotte collection, Museum de Paris (on loan at the A.M.N.H.).

Private collections (M. G. Bingham, J. Deligne, D. H. Kistner, C. Noirot, J. M. Pasteels) and unidentified specimens both from the N.C.I, and from the collections of the Lovanium University, Kinshasa (U.Lov.), where this work has been com- pleted, must also be mentioned here, as totalizing nearly 900 of all the nest series examined.

The abbreviations given in brackets indicate the museum of deposit, when listing material in the text ; if the specimen concerned has not been examined by the author, the museum of deposit is given in brackets. Localities not indexed in the

TERMITES OF THE GENUS MACROTERMES 367

Times Atlas, vol. IV, or homonymous within the same country (e.g. Katanda, Congo) are specified by their co-ordinates of latitude and longitude.

METHODS

The species involved in this revision have been redescribed and a full set of illustrations has been prepared. Previous descriptions have been translated or quoted whenever the characters involved have been found both useful and clearly expressed ; in such cases they are integrated into the standardized layout that has been adopted throughout this work.

Many characters utilized in earlier descriptions of species have been found un- necessary for this generic revision ; others have proved more variable within one species than was previously thought ; the following have been newly used or found of greater importance than hitherto recognized :

Imago : density of setae on head capsule

Soldiers : head profile

shape of metanotum pilosity of gula

The figures have been drawn with the aid of a camera lucida, from ethanol- preserved specimens immersed in ethanol ; three scales are used, each of the two larger being twice the next smaller. The largest scale is used only to illustrate the inner margin of the left mandible in the minor soldiers (Text-figs 18, 19, 90) ; the smallest, for the major soldiers throughout, the major workers (Text-figs 20-22) and the minor soldiers, with the exception of M. ivorensis (Text-figs 46, 47) which is on the intermediate scale, as are the imagos. In some cases (e.g. Text-figs 70, 123) the drawings include details of the light marks on the cuticle. Antennal segments have not been illustrated and the setae are usually omitted, except when conspicuously dense.

With regard to the measurements, it should be noted that the length of the pronotum has been taken on the median line in the imagos, on the longest lateral lobe (left or right as the case may be) in the soldiers. The head-width across eyes in the imagos is measured in dorsal view, from the extremes of curvature of the eyes ; in the soldiers it is the greatest width, wherever it occurs. Similarly the depth of the head capsule in the soldiers is taken as the distance in profile view from the postmentum (or the lowest point of curvature of the ventral genae, whichever protrudes most) to the highest point of curvature of the vertex, in a line perpen- dicular to the longitudinal axis of the head. The length of the fore wing is measured from the suture line to the apical point ; the diameter of the eye is its greatest one ; the length of the ocellus includes its posterior, non-translucent part ; and, when measuring the length of the hind tibia (usually the left one), care was taken to put it at an angle with the femur in order to get the full length of the chitinized sheath. For the abbreviations used and for other specifications (concerning the head length and the length of left mandible in the soldiers), see the keys to species. Finally, as experience has shown that various people using various optical devices may find slightly different values in measuring the same object, the upper and lower ranges of dimensions incorporated in the keys have been checked for possible

discrepancies of the kind.

The colour scale adopted in this work ranges from pale yellow to pitch-black, with (reddish yellow, amber, orange-brown, chestnut-brown) or without (brownish yellow, brown, smoky brown, sepia-brown) a red shade.

Imago. Large, width of head across eyes 2-8 to 4-5 mm, length of fore wing 24 to 43 mm ; head oval, postclypeus same colour as, or lighter than, head capsule, barely to distinctly inflated ; fontanelle inconspicuous to distinctly protruding ; distance ocellus ex eye 1/4 to 4/3 of ocellus major diameter ; a subsidiary tooth on the first marginal of the right mandible ; antennae ig-jointed ; pilosity variable, but without microsetae distinct from the longer bristles.

Pronotum trapezoidal, index length/width 0-4 to 0-6.

Wings translucent to smoky brown ; mediana of the anterior wing isolated from the scale onwards ; intersegmental membrane of the abdomen in queens without setae.

(The characters of right mandible, pilosity, and mediana of fore wing are useful in separating Macrotermes from Odontotermes.)

Soldier. Dimorphic. Head length (without mandibles) of the major soldier 4-0 to 7-7 mm, of the minor 2-05 to 4-77 mm ; labrum widest at or before its middle, with a well-developed hyaline tip (acute to obtuse, sometimes lanceolate, faintly suggesting a trilobed one) ; mandibles swordlike, more or less slender and incurved, but without any conspicuous tooth near the middle of inner margin ; antennae 17 to i8-jointed ; gula narrow, at least twice, often three times longer than wide, sides subparallel to concave.

Pronotum sellate, distinctly bilobed, middle region of front margin more or less deeply incurved, but never with forward projecting spines.

Head capsule in major soldiers rectangular to pear-shaped, the length exceeding the maximum width by 15 to 50% of the latter. Pilosity variable. (Again, no macro- and microsetae.)

Minor soldier : size about half that of major soldier, similar in general appearance, but with mandibles more slender, antennae and legs often proportionately longer. Colour usually lighter.

(The overall size, the ubiquitous dimorphism of the caste with a general similarity between major and minor soldiers, the mandibles, the pronotum and the hyaline tip of the labrum are among the most important of the generic characters of Macrotermes soldiers.)

Worker. Dimorphic. Mandibles similar to those of the imagos. Head capsule rounded, width in the major caste 2-05 to 3-50, in the minor 1-33 to 2-41 mm.

Holmgren (1909) first created the genus Macrotermes with Termes lilljeborgi as type-species by monotypy ; subsequently (1910, 1911) he reduced it to subgeneric status and erroneously designated another species, M. carbonarius, as the type- species. In 1912 he listed all Indo-malayan species under this subgenus, while

TERMITES OF THE GENUS MACROTERMES 369

stating that the soldier of M. gilvus does not have its head constricted in front like the other Macrotermes ; his other subgenus, Termes, included T. bellicosus, T. goliath, T. michelli, T. natalensis and T. nigeriensis.

Fuller (1921) pointed out that the name Termes was invalid for this particular genus, and proposed instead the name Macrotermes.

Sjostedt (1926) created the genera Hepilitermes and Amplitermes in addition to Macrotermes. In the same work, however, he acknowledged (p. 366) the priority of the subgenus Bellicositermes, created by Emerson (1925).

Emerson (1928), while maintaining Macrotermes and Bellicositermes as subgenera of Macrotermes, expressed his doubts about the value of this subgeneric division. In his later publications as well as in his private communications, he dropped the name Bellicositermes altogether.

Grasse" (from 1937) and Noirot have maintained a generic division between Macrotermes and Bellicositermes up to the present day, although they noted (Grasse" & Noirot, 1951 : 330) that the Asiatic species did not fit very well in this distinction. In describing M . angolensis, Noirot (1955) remarked that the species had some mixed characters.

These authors have not taken into consideration M. vitrialatus, a widely variable form including several formerly recognized species as synonyms. This species finally invalidates any attempt to divide the genus into two, because it spans the inter-specific gap postulated by Grass6 & Noirot in both its ecology and morphology. It confirms the impression gained from the Asiatic and Indo-malayan species that this is one genus.

Some kind of infra-generic grouping may be valid and useful for descriptive purposes, but it is thought that this should be of an informal kind without nomen- clatural status.

DISTRIBUTION

This study being restricted to the Ethiopian species of one genus, the phylogeny of the group is not discussed here. The density of individual species throughout their geographical distribution is another point about which no definite, let alone quantitative, conclusions can be drawn, since a few countries only have been systematically searched. With these restrictions, the following may be noted :

Macrotermes has been collected over the whole of the Ethiopian Region, in a variety of habitats from rain forests to subarid zones bordering either the Sahara or the Kalahari deserts. It extends north-east to Southern Arabia, but records from Madagascar, already considered as doubtful by Emerson (1928 : 445), have not been confirmed.

The forest species : M. ivorensis, M. lilljeborgi, M. muelleri, M. nobilis (Emerson, 1928 : 441 ; Grass6 & Noirot, 1951 : 309), seem indeed restricted to sheltered habitats, although they are not strictly confined to the lowland coastal or equatorial zones. M. muelleri does occur in many a riverine or secondary, low-canopied forest of minor area in the Congo basin, as illustrated by Weidner (1961 : 34) from Dundo, Angola. (Incidentally, no forest Macrotermes have been recorded south of this latter locality.)

370 J. E. RUELLE

The most widely distributed species, after the splitting of M. natalensis, is M. subhyalinus (formerly M. bellicosus). This species tolerates drier conditions than does M . bellicosus, as Grasse" & Noirot (1961 : 325) have already stated. The same authors, however, make it clear (loc. cit. and PI. XV) that M. subhyalinus can thrive in the equatorial forest.

M. bellicosus tolerates relatively dry conditions in West Africa, being found from the forest edge to the Sahel savanna (800-400 mm annual rainfall). Its abundance from Senegal to Uganda and in the Congo basin makes it hard to explain its absence from further south, although it should be noted that specimens from Congo forest clearings are larger than those from Northern Nigeria, suggesting a more favourable environment in the sub-climatic zones with abundant rains.

M . falciger, which ranges mainly in eastern and southern Africa, seems to have somewhat higher humidity requirements than M. mossambicus and M. natalensis. From the extensive collections made by the Plant Protection Research Institute of Pretoria, it appears that the two latter species, together with M. subhyalinus, are living in many places in South -West Africa where no M. falciger has been recorded.

Little can be said here of M. herus and M. ukuzii, in view of their limited dis- tribution. M. vitrialatus, through the range of climates under which it has been collected, compares most closely with M. falciger but for the fact that it extends farther to the north-west than the latter, while being apparently absent from Tanzania.

Additional notes, together with the distribution maps, will be found under the description ol each species, but more data are needed about the nutritional habits of Macrotermes before deciding whether and to what extent the presence or absence of some vegetation type regulates the geographical distribution of the individual species. Similarly, their soil requirements, if any, have failed to show up clearly in the course of this revision.

KEYS TO SPECIES

' The increased understanding of the variability of all castes has led to difficulties in constructing suitable keys to species. ( . . ) Some of the species are represented by very small numbers of specimens, and it is anticipated that discovery of new material may necessitate the reassessment of the validity of key characters in these cases.' (Sands, 1965 : 17). This holds true with Macrotermes. However, in species where numerous specimens could be examined, it has been found that mean numerical values are worth mentioning in the following keys. The text-figures should also help in appreciating some qualitative characters.

The above synonymy contains only entries of nomenclatural significance.

To correct all the subsequent misidentifications in the synonymy would obscure the nomenclatural entries. It is therefore to be noted that citations of the species- name natalensis under the generic headings of Amplitermes, Macrotermes or Bellicosi- termes in the literature (e.g. Sjostedt, 1926 ; Emerson, 1928 ; Grasse & Noirot, 1951, 1955, 1958, 1961) and not included in the material examined in this revision, should henceforward be referred to M. bellicosus, but only if recorded from the geographical range of this species.

Head rounded, numerous setae on head and pronotum, with light dots around base. Frons flat, not depressed around fontanelle ; fontanelle conspicuous, on top of a small hump, without any anterior median ridge (opp. natalensis). Eyes broadly oval, large, but less rounded than in subhyalinus and less inflated than in mossambicus. Ocelli nearly circular, not more than about J of their diameter distant from the eyes (£ in natalensis). Postclypeus wider and more inflated than in subhyalinus. Antennae ig-jointed, third segment longer than second and fourth.

Pronotum with anterior margin flat, posterior broadly indentated ; proportionately wider than in subhyalinus.

Variation. Lateral expansions of the mesonotum may make it occasionally wider than the metanotum, in the major soldiers. In a sample of 50 specimens from 19 localities, this was the case with 27 specimens. In point of size, the West African specimens are smaller than those from Central Africa, the average difference being 0-2 mm for head width of imago and head length of minor soldier, 0-5 for head length of major soldier, 6 • o for length of fore wing in alates. But the only non-overlapping figures are those of the wing length and this character alone does not seem to warrant a subspecific distinction.

The termites from the oldest collections of the Linnean Society (London) include one unlabelled major soldier of M. bellicosus and two minor soldiers, labelled : ' Termes bellicosus milites Smeathman, Termes fatalis L. milites '. These two minor soldiers belong to one species of Macrotermes, the specific determination of which could not be ascertained. Since there is neither an indication of locality nor any resemblance of the writing on the labels to Solander's writing, it has been concluded that Smeathman's types are lost. A neotype from Sierra Leone has been selected from the B.M.(N.H.) collections. Although Freetown is nearer to the place where Smeathman had made his observations, a sample from a mature colony at Njala has been chosen, since the material available from Freetown is less satis- factory (immature colonies).

Evidence obtained in the course of this revision has revealed both a morphological and a geographical gap between what used to be called M. natalensis in West and Central Africa and the species described by Haviland ; hence the present splitting.

The type imago of Termes nigeriensis Sjostedt could not be found in the Stockholm collections ; the ' topotype ', as labelled by Dr A. E. Emerson (unpublished), and any other samples of ' M. nigeriensis ' from the same region are indiscernible from M. bellicosus.

Termes carboniceps Sjostedt, known by the soldier caste only, is a larger than

Neither Dundo nor a few other, not listed above, records from the Ivory Coast (Abidjan, Bingerville, Kouibli, Man) or former French Equatorial Africa (Bossem- bele1, Makoua) have been substantiated by redetermination and the localities have not been plotted on the distribution map. The determinations, however, are thought reliable (Weidner, 1956 ; Grasse", Grasse" & Noirot passim], the name ' natalensis ' meaning ' bellicosus '.

The biology and the ecology of M. bellicosus have already been extensively studied (Smeathman, 1781 ; Grasse", 19370, 1944 ; Kutter, 1943 ; Grass6 & Noirot, 1951, J955.

Major worker. Head dark chestnut-brown, posterior margin rounded ; width (138 speci- mens from 36 localities) : range 2-64-3-50, mean 2-99 mm.

Variation. This species is generally darker in colour than M. subhyalinus, but not always. Neither can one rely on the index mesonotum width/metanotum width or on the concavity of the hind margin of metanotum in major soldiers to separate M. falciger from M. subhyalinus. Although the evidence is as yet inconclusive, paler specimens and shorter wings seem more frequent in South Africa than elsewhere.

The type-collection of M. falciger in the Hamburg Museum had been considered in 1898 by Sjostedt as Termes bellicosus (date of hand-written label found with the sample). The re-determination by the present author was first communicated to Dr H. Weidner and published by him (1966 : 224) as follows : Nach J. E. Ruelle in litt. : Macrotermes goliath (Sjostedt). According to the law of priority, the name ' goliath ' can not be maintained.

Sjostedt's note (1926 : 85) on T. michelli von Rosen has proved right. T. swaziae and M. usutu Fuller were already regarded as possible synonyms of M. falciger by Dr A. E. Emerson (in litt.) ; and, indeed, the samples from South Africa are even closer to those from East Africa than the samples of M. bellicosus from Nigeria are to those from the Congo. Tumulitermes kibonotensis had entirely disappeared from Sjostedt's work between 1924 and 1926. No type material of this species has been found and it must be presumed lost. A neotype has thus been selected to establish this synonymy.

M. falciger is predominantly a woodland species. Its typical habitats in Zambia and Rhodesia are the Brachystegia woodlands on hillsides and it seems to require

very well-drained soils (M. G. Bingham, in litt.}. The workers occasionally leave their mud galleries to forage in the open, even in broad daylight (Fuller, 1915 : 466 ; Bingham and W. G. H. Coaton, in litt.},

This species is not the only Macrotermes that can be collected from huge, massive mounds. Specific behaviour (Harris, 1956 ; 1961 : 35 ; Coaton, 19620) is not involved here and the large termite hills, found to contain M. subhyalinus (Grasse & Noirot, 1957, 1961), M. bellicosus, Pseudacanthotermes and other genera (own

observation) , in various parts of Africa, are, like those of M. falciger, the result of a long story of successive recolonizations at the same site. The name ' goliath ' has been misleading.

It is still not clear whether the architectural potential of M. falciger, under similar circumstances, differs from that of the partially sympatric M. subhyalinus. P. B. Kemp (1955 : 130) found no differences between their nests in North-Eastern Tanzania. Pictures published by Coaton (1962 : 68, 69) suggest that M. falciger in Zambia builds low hummocks whereas M . subhyalinus erects tall, spired mounds. This, however, was negated by the determination of the insects concerned.

More data are also wanted about the regular presence of a royal chamber. The published evidence is inconclusive, for M. falciger (Sjostedt, 19074:, pi. 3 ; opp. Fuller, 1915 : 466) as well as for M. subhyalinus (Grassd & Noirot, 1961 : fig. 14 ; opp. Weidner, 1961 : 38). In comparison, M. bellicosus regularly builds such a cell ; M. muelleri does not.

Finally, the swarming behaviour of M . falciger has already been described from Tanzania, Kilimandjaro and Malawi, Somba (? Zomba) by Sjostedt (19000 : 95 ; 1926 : 84). In Zambia, this species emerges just after dark, M. subhyalinus around midnight (M. G. Bingham, in litt.}.

Major worker. Similar to that of M. subhyalinus, but smaller ; head width (47 specimens from ii localities) : range 2-02-2-75, mean 2-48 mm.

Variation. The darker specimens of this species have been collected at higher altitudes (up to 7,800 ft) in Ethiopia. The backward location of the fontanelle is in fact too variable to provide a specific distinction from the closely similar M. subhyalinus major soldiers, but it does suggest a transition between the Ethiopian and the Indo-Malayan Macrotermes (of which six species, cursorily examined at the B.M.(N.H.), had their fontanelle at between 38 and 53% of HL ; the highest value found in M ' . herus — and in any Ethiopian Macrotermes — being 42).

J. E. RUELLE

The specimens listed below, when previously identified at all, had been labelled in the collections examined as ' bellicosus ' (7 samples), ' natalensis ' (4), even ' herus ' (2). This suggests that M. herus is very close to M. subhyalinus and M. bellicosus. However, to say nothing of the dark coloration (because it may simply be correlated with altitude), the eyes and ocelli are definitely smaller and farther apart in M. herus images than in those of M. subhyalinus, and the hind tibiae are also shorter. The difference between soldiers is more a matter of size than of proportions, although the head is somewhat more flattened and the mandibles less incurved in M, herus major soldiers than in M. subhyalinus. With respect to M. bellicosus, the head- depth, the ridge and grooves in front of the fontanelle and the sclerotization of the thoracic nota usually provide a good distinction. While realizing that further research may reduce M. herus to a local variant of M. subhyalinus, the evidence at

The following notes should be added to the original description :

Soldiers. Head capsule definitely more setose than in M. muelleri ; major soldiers usually lighter than those of M. nobilis ; minor soldiers with a head thicker and less elongate than that of M. muelleri, the anterior third of the gula in side view diverging more from the underside of the head capsule, the gula itself being proportionately wider (being also wider than the gula of M. nobilis minor soldier).

Major worker. Similar to, but smaller than, those of M. muelleri and M. nobilis ; head width (17 specimens from 4 localities) : range 2-21-2-67, mean 2-47 mm.

With regard to the figures published by Grass£ & Noirot, it will be noted that they extend the upper range of the head length in major soldiers to 6 mm, of the head width in the same to 5-15, and of the hind tibia in minor soldiers to 3-92. As compared with the figures found in the course of this revision, this last result is not too surprising, since another forest Macrotermes has yielded precisely the same range for the similar segment in samples from the same locality (M. muelleri, mature colonies from Mondongo, Congo : 3-26 to 3-97 mm ; the overall range for this latter species being still larger).

The major soldier of M. lilljeborgi has very long mandibles. Even with the 4-14 mm measured by Emerson (1928 : 442), the whole range is still beyond that of any other Macrotermes.

Sjostedt (19000 : 84, 91) mentions the deep indentation of the front margin of the pronotum in the major worker. This has also been observed in the soldier caste ; the segment, however, remains quite different from that of Pseudacanthotermes.

A total of 9 nest series were examined. Two samples, from Kribi (Mus. Berlin ; Sjostedt, 19000 : 87) and San Benito River (Museum Paris ; Sjostedt, 1904 : 49), could not be examined ; the determinations being thought reliable, the localities have accordingly been reported on Map 5, above.

Neither Sjostedt (1896) nor Silvestri (1914) could find the nest, and the imago of M. lilljeborgi is therefore unknown. Since this caste has not been collected, the minor workers do not seem to accompany the foraging expeditions.

The geographical range of the species is thought to extend from the Cameroon to primary forest regions of the Congo, near the Equator. The scanty material suggests that other forest Macrotermes, esp. M. muelleri, are much more abundant than M. lilljeborgi, or at least much easier to find.

Major worker. Head capsule reddish brown, in plan view posteriorly rounded ; head width (126 specimens from 35 localities) : range 2-11-2-91, mean 2-54 mm.

Variation. In the images, Sjostedt (i9i4«) had noticed that the pronotum is wider than the head across eyes ; this does not constitute a specific character. Neither is the fore wing always wider in M. mossambicus than in M. subhyalinus. Otherwise, in this and in the soldier caste, no consistent geographic variation has been found worth mentioning.

This species is similar to M. subhyalinus ; the ranges of quantitative characters overlap broadly. However, in the images the pilosity of the head capsule and the large size of the eyes and ocelli, in the major soldier the overall size, the curvature of the left mandible and the profile of the head capsule, in the minor soldiers the width and the angular shape of the metanotum usually allow a correct identification at first glance. (The difference between mesonotum and metanotum width in major soldiers is not a reliable character, although the metanotum is, more often than not, wider than the mesonotum in M. mossambicus.}

In addition to specimens of M. michaelseni, the junior synonym, the material listed below includes quite a few samples (from Malawi, Rhodesia and South Africa) that had been identified by Fuller as ' M. bellicosus ' or a variety of it.

Climatic data (Coaton, private communication) indicate that M. mossambicus can live in fairly dry sub-regions : Okahandja (annual rainfall range, 350-400 mm), Usakos (150-200 mm). In Zambia and Rhodesia, this species is common only in the Zambezi valley area, has not been found at altitudes higher than 1200 m, and tolerates poorly drained, alluvial soils (M. G. Bingham, in litt.). In South Africa, it has not been found at higher latitudes than the north-eastern corner of Natal.

The mounds have been described as tall, hard, conical by Michaelsen (in Sjostedt, 1926 : 88) ; Weidner (1961 : 42) records a height of 3-5 m from Angola ; Bingham (in litt.) has measured in Zambia a mound 3 m high and 3 x 2 m at the base. No queen cell has hitherto been described, but Fuller's collecting data (1922 : 73) seem to imply its presence.

Alates have been caught near Rekomitjie, swarming soon after dark in the last days of November. Little else is known on the behaviour and ecology of M. mossambicus.

After shifting the species to Macrotermes, he took the species-name Miilleri again (1926). He was entitled to do this, since Termes Mulleri von Ihering lacks a description and therefore is not valid.)

Pronotum with four light marks on the limit between anterior and posterior lobes. Abdominal sternites lighter than tergites and femora lighter than tibiae. Wings smoky brown, with darker veins.

Head in plan view oval, strongly tapering towards anterior end, with a very few, scattered bristles. Fontanelle depressed, inconspicuous and not surrounded by small hairs. Eyes relatively small, not prominent ; ocelli broadly oval, distant from the eyes by a little less than their major diameter. Postclypeus almost flat. Antennae ig-jointed, third segment distinctly longer than others.

Pronotum more than twice as wide as long, but usually narrower than head across eyes ; front margin straight to concave, barely emarginate in the middle, hind margin emarginate, a few short hairs on margins.

Major worker. Head capsule reddish brown, darker above antennal sockets ; in plan view paraboloid, maximum width near external articulation of mandibles ; this width (89 specimens from 17 localities) : range 2-50-2-93, mean 2-73 mm.

Variation. In spite of Text-fig. 70, which is given as an example, the light marks on the pronotum are not species-specific : they are simply more conspicuous in dark-coloured speci- mens throughout the genus. The major soldiers of this species may be darker or lighter ; in the minor soldiers, the difference of coloration between thoracic and abdominal tergites may be nil to distinct. Some imagos (Emerson, 1928) have their pronotum wider than the head, but this is not the rule. The antennae may be i8-jointed in the soldier caste, both the minor (Weidner, 1961 : 33) and the major (Emerson, 1928 : 443). In the latter, the metanotum has always been found wider than the mesonotum.

Lastly, some samples from the Western part of the Congo (Text-fig. 72) are smaller than average ; no distinct subspecies, however, could be recognized.

The de-alated imagos of M. muelleri resemble those of M. vitrialatus ; their eyes, however,

TERMITES OF THE GENUS MACROTERMES

407

are usually bigger, their ocelli more elongate and their pronotum proportionately wider. The mean index pronotum length/pronotum width in the major soldier is the highest of the genus. The index hind tibia length/head width in minor soldiers, as studied by Grass6 & Noirot (1951 : 332), has been checked with the figures now available, and found slightly lower than previously thought : 1-95 (2-0). For comparison, M. bellicosus yields a value of i-oi, M. vitrialatus 1-44.

A total of 104 nest series were examined.

This species is the most abundant of the forest Macrotermes ; its distribution has already been discussed above. In view both of its habitat and of the extensive collections carried out in Nigeria and in southern regions of Africa, it is unlikely that further research will reveal significant differences from the present geographical range.

The nests have already been described (Grasse" & Noirot, 1951 ; Weidner, 1961 after de Barros Machado) ; but neither a queen cell nor even a physogastric queen could be found. An earlier account (E. Luja, quoted in Wasmann, 1911) is un- reliable, since the collector appears to have mixed M. bellicosus and M. muelleri in his field notes. Recently (1966), reproductive imagos were collected in the

TERMITES OF THE GENUS MACROTERMES

409

Congo (Mondongo) from two mounds, 2 -5 and 3 -o m high ; in both cases the queen was found in an ordinary nest chamber (well above ground level) and the male escaped detection. This, with previous fruitless efforts, and the literature cited, support the conclusion that M. muelleri usually does not enclose its royal pair in a distinctive chamber.

The circular or semi-circular leaf cuttings, brought home from the foraging expeditions and illustrated among others by Grass6 & Noirot (1951 : 315), are found

What has been said about M. bellicosus could be repeated here to help sorting out the misidentifications in the literature, such as those of Tragardh (1904 : 6), Was- mann (1911 : 92), Sjostedt (1913 : 363) (1915 : 12), Emerson (1928 : 447), Grasse" (19370, 1944), etc.

Imago. Head capsule chestnut to smoky brown, with lighter area around fontanelle ; post- clypeus lighter, with dark median line ; base of mandibles intermediate between head capsule and postclypeus, tip black. Pronotum slightly lighter than head, with a sometimes con- spicuous moth-shaped mark. Abdominal tergites and sternites not distinctly lighter than thorax. Tibiae darker than femora. Wings smoky.

Head in plan view rather short (i.e. the width across eyes is great in relation to the distance between the anterior margin of the postclypeus and the posterior margin of the head capsule), its hind margin regularly convex. Fontanelle in a depression, not very conspicuous, but surrounded by short setae and followed anteriorly by a median carina ; the head otherwise sparsely pilose. Eyes sub-pentagonal, neither large nor particularly prominent. Ocelli sub- circular to elongate, distant from the eye by about £ of their major diameter. Postclypeus wide (slightly wider and less inflated than in bellicosus}. Antennae ig-jointed, 3rd segment twice as long as 2nd.

Pronotum ' subsemilunar ' (Haviland), front and hind margins not or barely emarginate, lateral corners rounded, sides convex.

Hind tibia short.

Major soldier. Head capsule yellow to dark ferruginous brown, apical part darker than base, ventral side as often as not same colour as dorsal side ; gula, however, darker than ventral genae. Mandibles usually black throughout. Thorax lighter than head, margins of nota smoky brown. Tibiae barely, if at all, darker than femora ; tarsi darker than tibiae.

Head capsule in plan view ' ovate-quadrate ' (Haviland) to ' horseshoe-shaped ' (Fuller), sides moderately convex ; fontanelle more conspicuous than in M. bellicosus, i.e. wider and slightly protruding ; frontal grooves shallow, but sometimes similar to those of M. subhyalinus.

Sides of hyaline tip of labrum straight to convex. Mandibles long, upturned from the base (not really upcurved, as is the case with M. mossambicus) , moderately and fairly regularly incurved, left one not much wider than right. Antennae 17- to i8-jointed, ist segment longer than 3rd, 3rd longer than 4th, 2nd the shortest. Pilosity variable, rather sparse on head and thorax, often dense on abdomen ; lighter area around base of setae rarely conspicuous.

Anterior and posterior margins of pronotum equally indented, lobes rounded, antero-lateral sides notched ; meso- and metanotum nearly as wide as pronotum, sides rounded, hind margin of metanotum concave to straight ; the thoracic nota, on the whole, distinctly more chitinized than in M. bellicosus.

Abdominal sclerites slightly paler than thorax ; femora lighter than abdomen, tibiae same colour, tarsi darker.

Outline of head capsule in plan view similar to that of major soldier, although shorter and more rounded. Fontanelle conspicuous, but not protruding. Left mandible more incurved than right, and a little more near the tip than in basal part ; in ventral view without any distinct serration of the inner edge.

Sides of thoracic nota rounded, metanotum in most cases not distinctly wider than mesonotum.

Variation. Statistics on the variability of some quantitative characters can be found in Warren (1909, 1916). The ' natalensis — durbanensis ' variety, although somewhat larger than average, is not really different from the ' natalensis s. str.', ' nat. transvaalensis ' and other forms described by Fuller ; even specimens from South West Africa cannot be distinguished from those collected on the other side of the Kalahari desert.

This species has long been confused with M. bellicosus. The major soldiers nevertheless present a distinctive pattern in the dimensions of the left mandible, the hind tibia and the thoracic nota ; such differences were implied in Dr Emerson's unpublished comment on a sample of M. bellicosus from Sierra Leone (above). Also, the size of the minor soldiers is larger in M. natalensis. The imagos are usually separated by the pilosity and the width of the head capsule, the diameter of the eye (and the distance between eye and ocellus) and the length of the hind tibia ; the index length/width of the pronotum is less reliable.

A certain similarity with M. subhyalinus prompted Fuller's opinion (1915 : 458) on the probability of M. natalensis being a synonym of ' M. bellicosus ' ; more recently, Noirot (1960) identified as ' Bellicositermes bellicosus ? ' a sample of Macro- termes from the Outeniqua Mts (Cape Province). This tentative determination could not be checked, but in view of the geographic distribution found, and of the measurements taken, in the course of this revision, the doubtful sample most probably belongs to M. natalensis. As a matter of fact, this species has rarely been collected together with M. subhyalinus, but can easily be recognized from the latter in such cases by the mandibles of the major soldiers.

A lectotype imago and a morpholectotype major soldier have been selected from Haviland's type material ; they are listed below with some of the collecting localities.

A total of 551 nest series were examined.

This species is tolerant both of dry climates (some collecting localities in S.W. Africa have an annual rainfall range of 550 to 150 mm) and of cold seasons ; no other Macrotermes has been found in the Cape Province and the Orange Free State.

The nests have been described by Fuller (1921) and Coaton (1947) among other authors ; the reproductive images are usually enclosed in a distinct chamber. Swarming takes place in the second half of November, the alates emerging immedia- tely after dark (Fuller, 1915) .

Major worker. Head same colour as minor soldier, with a conspicuous white dot around the fontanelle ; in plan view nearly semi-circular, the maximum width (19 specimens from 5 localities) : range 2-52-2-88, mean 2-65 mm.

This species is closest to M. muelleri. The head capsule of the imago is less elongate, the ocelli more elongate, the postclypeus proportionately wider, the third antennal joint shorter, the pronotum proportionately shorter and the index hind tibia length/head width smaller. It should be noted, however, that the truly specific differences can not be asserted before the discovery of new material. In the major soldiers, the most obvious differences between the two species are the head shape and the lengths of the left mandible and of the hind tibia. The head of M. nobilis is narrower and less convergent, its mandible and hind tibia are definitely shorter. In addition, the pattern of light marks on the mesonotum seems different from that found in M. muelleri. The minor soldiers cannot be safely recognized ; the gula in M. nobilis is proportionately wider than in M. muelleri and the difference between the widths of meso- and metanotum is smaller ; but the left mandible and the hind tibia are here unreliable as taxonomic characters.

The nest structure and fungus combs of M. nobilis have been described from the Cameroon (Grasse & Noirot, 1951). A note by J. Deligne with his sample from Belinga Forest (Gabon) states : ' clay hummock '. Observations made while collecting the imago in a swampy area of primary forest confirm that the nests are low, dome-shaped, barely 50 cm high with a diameter exceeding 2 m ; which is strikingly different from the tall, mamillated mounds of M. muelleri in the same forest. (Each species has, incidentally, its own vernacular name). No distinctive queen cell was observed and the king could not be caught. The fungus combs are as figured by Grasse & Noirot (1951, PI. II, fig. 15 [not 14]).

As with M. bellicosus, the above synonymy contains only entries of nomenclatural significance. To list all the misidentifications that have followed Hagen's publica- tion would be beyond the scope of this revision. Suffice it here to quote some taxonomic papers (Silvestri, 1914 : 12, under the name of goliath ; Grasse, 1937^, 1944 ; Harris, 1936, 1948, 1957, 1963 ; Weidner, 1956, 1961), and to state that any citation of the species-name bellicosus under the generic headings of Amplitermes , Bellicositermes or Macrotermes in the literature and not included in the material examined or in the references cited in this revision, should be referred to M. sub- hyalinus.

Neotype, $ imago. Head capsule chestnut-brown ; postclypeus lighter than head, with a thin, dark, not very conspicuous median line. Pronotum same colour as head, a light T-shaped mark in the middle and two light dots near the antero-lateral corners ; abdominal tergites same colour as pronotum, sternites lighter. Legs less reddish-tinged than head capsule, tibiae slightly darker than femora. Wings yellowish brown.

Head capsule in plan view showing a distinctly depressed, semi-circular area around fontanelle; fontanelle itself protruding, surrounded by short setae, followed anteriorly by a narrow median ridge towards clypeus ; in side view vertex of head capsule evenly convex, rather than hog-backed (opp. bellicosus). Eyes big, not very prominent, rounded. Ocelli slightly elongate, distant from the eye by about ^ of their major diameter. Postclypeus moderately inflated. Antennae (in other specimens than the neotype) ig-jointed, 3rd segment the longest, and and 4th equal.

Major worker. Head capsule rich chestnut-brown ; in plan view, sides slightly convex, posterior margin rounded (Text-fig. 22). Head width (335 specimens from 114 localities) : range 2-18-3-27, mean 2-75 mm.

Variation. The imagos are smaller in West Africa (head width, 3-15-3-45 mm) than in East Africa (3-30-3-87), the specimens from Central Africa being intermediate ; the wings, in this last sub-region, are longer : 35-0-40-0 mm (East : 30-0-43-0, this upper limit being excep- tional ; West : 29-0-35-0). No variation clines in coloration or pilosity could be determined. The sculpturing of the head capsule as it appears in plan or oblique view is one of the most constant characters. No imagos were available from South-West Africa.

The largest major soldiers have been found in Central Africa, the smallest in South-West Africa (mean head length of 28 specimens from this sub-region, 5-55 mm). The index head depth/length of left mandible is more often inferior to i in Central Africa (80% of the specimens) than elsewhere (West and East Africa, 40%) : in other words, the head capsule appears flatter and/or the left mandible longer in Central Africa. In 182 randomly selected specimens from

82 localities, the index mesonotum width/metanotum width has been found greater than i in 115 cases : in other words, the mesonotum is often, not ' nearly always ' wider than the metano- tum (Grasse & Noirot, 1961). There are likewise many exceptions to the character ' hind margin of metanotum not concave '.

The largest minor soldiers have also been found in Central Africa, but they are only slightly larger than those of West Africa.

The images of M. subhyalinus usually have longer but fewer setae on the head capsule than those of M. bellicosus ; the T-shaped mark on the pronotum is often more conspicuous and the ocelli are bigger and more elongate ; the major soldiers of both species can be recognized by the overall size, the sculpturing of the forehead and the thoracic nota ; the minor soldiers mainly by the size and the left mandible ; the major workers by head shape and colour. The images of M. falciger, usually larger than those of M. subhyalinus, have proportionately smaller eyes and longer tibiae, the depressed area around the fontanelle also differs in shape ; major soldiers of falciger are usually darker and are furthermore characterized by their huge thoracic nota, their wide head, thick antennae and conspicuous pilosity of the gula ; the minor soldiers have longer tibiae and more incurved mandibles. The case of M. mossambicus has already been discussed.

The identification of specimens from some collecting areas : Ubangi-Uele- Uganda (bellicosus), Katanga-Zambia (falciger), South- West Africa (mossambicus), where M. subhyalinus has been found with the species given in brackets, can still be difficult. In the absence of any reliable evidence of inter-specific hybridization, this is attributed to the specific variability.

While meaning to complete Smeathman's description, Hagen (1855-1858) mistook specimens of M . subhyalinus for M. bellicostis. Most of the material examined by him — notably the Imhoff collection — has not been found in the European institu- tions ; but some of Rambur's and Latreille's specimens that had been passed to the Selys Longchamps collection (Desneux, 1915) were studied at the I.R.S.N., Bruxelles. The next available name for the species described by Hagen was T. subhyalinus Rambur (not T. capensis Latreille, 1804, since the latter author, mis- takenly quoted by Snyder (1949 : 209), was not describing a new species). The holotype has been lost, but the only other Macrotermes from the same country in the same collection belong to that species : hence the neotype and morphotype that have been selected and are listed below.

Types or syntypes of T. tumulicola Sjostedt and Bellicositermes bellicosus var. rex Grasse* & Noirot have also been examined.

Variation. The major soldiers have a strikingly pilose head capsule ; specimens from southern Tanzania, however, do not (see discussion below).

This species is closely related to M. natalensis. In the images, the postclypeus is more inflated and definitely longer in proportion to its width ; the ocelli are closer to the eyes and these are proportionately bigger ; the median ridge in front of the fontanelle is lower, not higher, than the fontanellar hump. The head capsule of

the major soldier, apart from its small size, is narrow (index head length/head width close to 1-5, the highest value in the genus) and pilose.

The holotype major soldier of T. parvus Holmgren is unusually small, even for M. ukuzii ; it agrees, however, with Fuller's specimens and the additional material examined. The probability that all of those nest series would be aberrant samples of a widely distributed species like M. mossambiciis or M. natalensis is not excluded, but is considered too low to prevent recognizing M. ukuzii as a distinct species. Hybrids, as Fuller (1927) seems to imply, are also possible, but this is a matter for field study.

The identity of the 3 samples from Tanzania is less certain, for reasons of geo- graphical gap, scarce pilosity of head capsule in major soldiers and large size of minor soldiers. Pending further evidence, however, they are assigned to M. ukuzii.

From the collecting dates, this species swarms in Transvaal at night, around the middle of November. (M. natalensis swarms at the same time, at least in Komatipoort.)

Variation. The outline of the head capsule in the major soldier is variable (Text-figs 139- 146). Besides a denser pilosity found in some South African specimens, other samples from Western Congo are smaller and more rounded. Still others, from Kwango and adjacent Angola, have a trapezoidal outline with sides nearly straight ; the lateral corners of the pronotum are also more acute and the mandibles less incurved than usual. Imagos are not distinctive to the same extent. However, it is worth noting that native people from northern Angola use different vernacular names for the specimens from Dundo (the usual form, called ' lungo ') and for those from Camissombo-Capaia and Caluango (this variant, called ' Ikhala '). These observations have been communicated, with some doubts, by a well-known field naturalist (A. de Barros Machado, in lift.). It is thus anticipated that a new subspecies may be created when more,

and more complete, samples, including all castes and collected in the same locality, will be available. For the time being, the evidence is still considered insufficient.

The following notes are added here to the comparison already made between this species and M. muelleri (above) : The imago of M. vitrialatus has the smallest eyes in the whole genus : index H/E 3-93 (in M. muelleri 3*38, in M. bellicosus 2-87) ; the postclypeus also looks relatively longer and slightly more prominent than in M. muelleri. The major soldier's head capsule in M. vitrialatus is less narrowed in front, the pronotum is proportionately wider and its sides are more rounded than is the case with M. muelleri. The gula in the minor soldier is shorter and wider than in M. nobilis and M. muelleri ; the 3rd antennal joint is longer than the 4th in muelleri. (Incidentally, it may be noted that seven of the species redescribed in this work have in the major soldiers a left mandible that averages more than half of the head length : falciger, herus, ivorensis, lilljeborgi, muelleri, natalensis, vitria- latus.}

A total of 89 nest series were examined.

This species was described under six different names from 1899 to 1955 ; in the collections, some samples had been identified as M. natalensis and one other mis- identification should be quoted here (Sjostedt, 1911 : 143 ; ' Termes bellicosus ').

The case of T. imperator parallels that of T. carboniceps with samples of unusually large soldiers. (At the lower range we have here M. angolensis.) T. vitrialatus and A. mozambicanus were first represented by alates only and collected far apart. It may be noted that M. schoutedeni had already been considered as a synonym of M. vitrialatus before this revision was undertaken (A. E. Emerson, private com- munication). As regards M. waterbergi, sufficient evidence has been gathered from Transvaal and Rhodesia since Fuller's time to leave little doubt about its status, in spite of its somewhat more conspicuous pilosity. The specimens from some parts of Angola have been discussed above.

M. vitrialatus may be more abundant than it looks from the distribution map ; its nests indeed are often inconspicuous, even completely subterranean. They are aptly described by Fuller (1921, 26) as mounds ' of loose soil, not unlike that of new grave ' : this has been confirmed since in South Africa and Angola (Coaton, de Barros Machado, in litt.) as well as in the Congo, near Kinshasa. Harder hummocks do occur, however, on more clayey soils, e.g. the region around Thysville. (The fig. 3 in Noirot, 1955 : 144, which looks like a nest of M. bellicosus, could unfortunately not be checked by redetermination of the sample.)

Although this is not a forest species, its major workers cut leaf fragments in a fashion similar to that observed with M. muelleri, as has already been noted. Reports from South Africa and Rhodesia (Coaton, Bingham, in litt.} agree with the observations made in the Congo.

TERMITES OF THE GENUS MACROTERMES

439

The foraging behaviour in broad daylight, as observed with the type collection of T. imperator, has also been observed near Kinshasa ; according to Bingham and Coaton, it further occurs with M. falciger in Rhodesia and South Africa. This ethological trait is not, therefore, a characteristic of the forest Macrotermes.

The evidence available suggests that M. vitrialatus, unlike other Macrotermes, does not swarm at the onset of the rainy season (alates have been collected towards the end of it, in the Congo) ; as far as is known, the images would take off immedi- ately after dark rather than in the morning.

ADDENDUM : DOUBTFUL PLACES

It has proved impossible to trace some localities on the maps available. Those which have not been cited in this work as : X. (co-ordinates unknown) are listed below with the species concerned and the place of deposit. Vague indications such as ' Kafferlandet ', ' Deutsch Ost-Afrika ' and the like — including 33 nest series- have been omitted altogether (save for the type specimens).

ACKNOWLEDGEMENTS

First of all I thank Prof. Albert Bouillon, of the Lovanium University, Kinshasa, for starting my interest in Macrotermes early in 1959 and for providing all kinds of facilities — including financial support — throughout this study.

Next I wish to express my gratitude to Dr W. V. Harris, Officer-in-Charge, Termite Research Unit, British Museum (Natural History), for access to the London and Cambridge collections since 1962, not less than for helpful advice and encourage- ment ; to Mr W. A. Sands, of the same unit, I owe much of the enlightening remarks and constructive criticism in the preparation of this revision.

My special thanks go to Dr A. E. Emerson for liberal communication of his long experience and unique collection of data on termites as well as for his hospitality at home ; in the same year (1967) I enjoyed staying at the American Museum of Natural History, New York, with all the facilities generously provided by Jerome G. Rozen Jr., Curator of the Department of Entomology, and especially with the warm helpfulness of Dr Kumar Krishna.

Among other curators, Dr P. Basilewsky, Department of Entomology, Musee Royal de 1'Afrique Centrale, Tervuren, should have been mentioned first ; for he not only welcomed me to work on his rich termite collections in 1965, but at the same time enabled me to borrow, thanks to the kindness of Dr E. Kjellander, Stockholm and of Dr H. Weidner, Hamburg, the all-important collections kept in the latter institutions. Special circumstances (my usual residence in the Congo) made the sojourn at Tervuren the more valuable.

In spite of the insecurity attributed to the same Congo, Dr W. G. H. Coaton, of the Plant Protection Research Institute, Pretoria, did not hesitate to send to Kinshasa the bulk of the N.C.I, collections, of which many specimens have been donated by him to Lovanium University ; this, and the useful collecting notes he added, well deserve a detailed acknowledgement.

Dr Cooreman, Institut Royal des Sciences Naturelles, Bruxelles, and Prof. C. Noirot, Faculte des Sciences, Universite de Dijon, have helped me in providing access to, and in sending samples from, their invaluable accessions. To Prof. Noirot I will add Messrs A. de Barros Machado and M. G. Bingham, when it comes to acknowledging not only the liberal communication of samples, but also the very interesting field notes gathered by experienced observers in parts of Africa that I was

TERMITES OF THE GENUS MACROTERMES 441

unable to visit myself. I am also grateful to Drs J. Deligne, D. H. Kistner, and J. M. Pasteels for their collections ; not to forget the help received at Basel from Dr Eb. Ernst.

Finally, my thanks are due to Miss M. Van Hove for help with the drawings and the distribution maps, and to other people working in the laboratory of Prof. A. Bouillon.
