LANSBURY MCZ LIBRARY Oxford University Museum, United Kingdom NOTES ON THE MARINE-FRESHWATER GERRID GENUS RHEUMATOMETROIDES (HEMIP TERA, SEP 1 4 1999 HARVARD UNIVERSITY GERRIDAE) OF PAPUA NEW GUINEA Lansbury, I., 1992. Notes on the marine-freshwater gerrid genus Rheumatometroides (Hemiptera, Gerridae) of Papua New Guinea. — Tijdschrift voor Entomologie 135: 1-10, figs. 1-43, tables 1-4. assN 0040-7496]. Published 15 July 1992. The marine-freshwater gerrid Rheumatometroides Hungerford and Matsuda from Madang Province, Nagada Harbour were studied in February-March 1990 and the results compared with data from West New Britain, Kimbe area. Rheumatometroides serena sp. n. is described from Negada Harbour, and compared with À. brown: Hungerford and Matsuda, originally de- scribed from Solomon Islands and now recorded from West New Britain. Variation between females of R. browni from West New Britain and Solomon Islands is commented upon. Notes are given on the habitat preferences of both species in Papua New Guinea and their localised distribution compared with other marine bugs (Gerridae and Veliidae). I. Lansbury, Hope Entomological Collections, University Museum, Oxford, OX1 3PW, United Kingdom. The genus Rheumatometroides Hungerford and Matsuda (1958) was described from the Solomons Islands, Kolombangara. No comment was made on the habitat of this genus. E. S. Brown, who collected the original series, describes the habitat in his field notes as ‘surface of river running into lagoon (Jack Harbour). Slow flowing’. Specimens were collected on the Ist and 14th October, 1954. Matsuda (1960) redescribed the genus comparing it with other genera of the Trepobatinae Matsuda. Andersen and Polhemus (1976) refer briefly to Rheumatometroides and a closely related genus Stenobates Esaki, com- menting that such records as there are indicate that both are marine occurring in estuaries and nearshore localities. Lansbury (1989) briefly summarises textual references to date. In 1990 I visited the Christensen Research Institute (cri), Madang, Papua New Guinea and the north coast of West New Britain, Kimbe area, to study marine bug. A new species of Rheumatometroides was found at Nagada Harbour (cri) and À. browni Hungerford and Matsuda was found in both freshwater and the intertidal zone in West New Britain, and what appears to be a form identical with that from Nagada, offshore in West New Britain. 24 Christensen Research Madang, Papua New Guinea. ' Publication nr. Institute, Samples were collected both by handnet during daylight and other samples were obtained using a light trap run from the end of the CRI jetty. Two immature stages of À. browni and a late instar of the new species are briefly described. SYSTEMATICS Rheumatometroides serena sp. n.

This species is dedicated to Mrs Serena Jebb, wife of the Director, Dr. M. Jebb of the Christensen Research Institute, Madang, P. N. G. Remarks. — R. serena with R. agaaga Lansbury and R. metawa Lansbury (Solomon Islands) form a dis- tinct group based on the male front tibia, which is strongly produced, whereas that of R. browni is not so produced. The omphalium of À serena is in the cen- tre of the metasternum as are all the foregoing insects. According to Matsuda (1960) the omphalium of the closely allied Stenobates is more conspicuous and lo- cated at the intersegmental suture between the meso and metasternum. Andersen (1982) distinguishes Stenobates from Rheumatometroides by the former having the metasternum distinctly produced, whereas the latter is not produced. Rheumatometroides serena is distinguished from À. agaaga and À metawa (only males known) by the colour pattern. The 3rd and 4th antennal segments of R. metawa are almost subequal as are those of À. sere- na, wheras R. agaaga has the 4th segment longer. Rheumatometroides serena also resembles R. metawa. However, R. serena has as shorter mesonotum 2 me- dian pronotal length compared with R. metawa, mes- onotum 2.75 X longer than median pronotal length. The anterior suture between the meso and metaster- num of R. metawa is antero-mesially produced, in R. serena it is evenly rounded.

Remarks. — The series from West New Britain compared with those from the Solomon Islands ap- pear to be very similar externally, especially the colour pattern and general external morphology. The differ- ences noted in the female ovipositor and ancilliary structures of the two populations (shape of gonocox- al plate, length of paired styli, distribution of blunt serrations and apparent absence of a ventral spatulate projection on 2nd gonapophyses, as figs. 27, 29), principally may indicate that the form from West New Britain may be distinct from the Solomon Islands form. The male genitalia appear to offer little to support this hypothesis at present. LANSBURY: Rheumatometroides of Papua New Guinea MISCELLANEOUS BIOLOGICAL NOTES Between 23 February and 16 March, R. serena was collected on a number of occasions. The first speci- men was recorded on 22 February, when a female was collected from beneath the CRI jetty walkway at 5 pm. Subsequent searches for a number of days starting at 7 am through to late afternoon failed to find any more specimens in the intertidal zone and more exposed areas, although occasional specimens were seen most days in late afternoon in the shade of the walkway. Scattered adult Halobates Eschscholtz (Gerridae) and aggregations of Halovelia Bergroth s. l. (Veliidae) (adults and immatures) were frequently seen. Eventually numbers of À. serena were found in the interstices of a coral rubble wall built to prevent erosion (8-9 March). This species appears to shun di- rect sunlight and exposed areas. A number of samples were collected at light (mvlt) between 25 February and 16 March. The light was run between 8-9.30 pm from the end of the jetty over water always in excess of two m deep. The largest number was found on 27 February (11 males, 6 females, 28 immatures), low ti- de 1.2 m, high tide 1.45 m, and on 1 March (10 ma- les, 14 females, 10 immatures), low tide 1 m, high ti- de 1.5 m. It is not clear if the samples taken at light came from the populations living amongst the coral rubble, or another population which was living bene- ath the main landing stage. This structure is sup- ported by a series of piers made of tyres filled with concrete. Between each tyre a layer of concrete was used, which has numerous crannies. The area around the landing stage provides shelter for many Halobates and veliids. A mvlt sample collected on 13 March in- cluded approximately 70 adult and 360 immature Halobates and about 200 veliids. An aggregation ta- ken on 1 March during daylight within one m of sho- re included 200 immature Halobates, 500 Halovelia adults and 1700 immature, but no Rheumatometroides. Colonies of Halovelia were set up in large tanks to study their behaviour. Inadvertently small numbers of R. serena were also introduced. Veliid mortality was extremely high under these conditions, whereas the gerrids survived. Adult À. serena were watched grooming, the tip of the rostrum is ‘cleaned’ with the tarsi of the front legs, longer middle legs are used to groom the hind legs. At rest, the gerrid supports itself on the tarsi. The first antennal segment is held curv- ing outwards, the second and third are always aligned in a more or less straight line, the fourth curved over at internodial piece, the alignment forming a shallow sickle-like outline. Live gerrids which were inadver- tently transferred to diluted sea water quickly suc- cumbed and drowned in the laboratory. Rheumatometroides browni appears to be far more tol- erant of lower salinities. Specimens were found up to TIJDSCHRIFT VOOR ENTOMOLOGIE, VOLUME 135, 1992 200 m upstream in West New Britain, Tamari Creek. Habitat preferences from both regions (Solomon Islands and West New Britain) seem to be similar, À browni occurring in the zone where freshwater flows into the sea. At Dami Creek, at low tide the creek ap- pears not to receive any inflow of sea water, but the freshwater continues to flow down the beach into the sea (pers. obs.). Rheumatometroides tends to skate across the surface in a series of short fast spurts. Unlike Halobates, it does not leap across the water to avoid the net. The colony living amongst the coral rubble proved diffi- cult to collect as individuals would run across the rub- ble hiding in small cracks or getting behind the rub- ble where the substrate was moist. Between 22 February and 16 March no pairs were seen in copula and no females were seen ovipositing.

Representatives of the gerrine genus Limnometra are restricted to tropical Asia, although three speci- mens have been recorded from Tanzania (Hun- gerford & Matsuda 1958). We presume that the spec- imens from Africa are incorrectly labelled, since they belong to a large species never collected in that area again. The present paper is mainly based on material re- cently collected in Sulawesi, where several species oc- cur as a frequent component of the surface fauna of streams. When we started working up the material it soon turned out that we had several new species at hand. The examination of unidentified material from Malesia in several museum collections revealed even more species, so that we decided to report on this ge- nus separately. A paper on the remaining Gerridae from Sulawesi is in preparation. MATERIAL AND METHODS Specimens from Sulawesi were mainly collected by J.P. Duffels (zma), J. van Tol (RMNH) and N. Nieser. Localities sampled by Nieser have numbers starting with N89 followed by two digits. All were taken in Sulawesi Tenggara (SE Sulawesi) and Buton in 1989. Details of localities can be found in Nieser & Chen (1991). In addition, specimens from G. Zimmer- mann's collection (zc), collected within the fra- mework of Project Wallace 1985, and by Dr. I. Lansbury (oxum) from other places in Southeast Asia have been studied. Although the number of species in the genus Limnometra is apparently large, there are very few dis- tinctive characters. The colour pattern on head and thorax, which is usually very striking, is, apart from a few exceptions, very uniform. The parameres are all of the same shape, small, rod-like with the base slight- ly broader than the apex. The general shape of the genital segments is also quite similar in most species. In various cases identification has to rely on relative measurements, pilosity of the legs and annulation on legs and antennae. In addition, we found that the en- dosomal sclerites, especially the lateral pair, provide specific characters in some cases. For this purpose the endosoma has to be cleared, for which we used hot 10% KOH, and made free from the basal plate and phallotheca which enclose it. As the endosoma has to be studied from various angles, permanent micro- scopic slides are less appropriate than keeping it in a drop of glycerin in a microvial. There are usually four sclerites, a medio-dorsal and a ventral one, which are usually seen as one sclerite forming a wide arc within the endosoma. Secondly, there is a symmetrical pair of smaller lateral sclerites. We consider the open end of the arc as posterior and the thicker posterior Y- shaped part of the arc as dorsal, which corresponds to the active condition of the endosoma. Measurements are in millimeters, presented as the range or the average value of five specimens (of each sex). Measurements were taken from specimens of the sample containing the holotype. In case of small sam- ples additional specimens from other sites were used. The width of the head is measured across the eyes, the thoracic width is measured across the mesoacetabula. 11 TiJDSCHRIFT VOOR ENTOMOLOGIE, VOLUME 135, 1992 Depositories NC Nieser collection, Tiel, The Netherlands.

Some workers, e.g. Hungerford & Matsuda (1958), consi- der it to be a distinct genus, while Matsuda (1960) and Andersen (1982) rank it as a subgenus in Tenagogonus Stal. Although Limnometra and Tenagogonus are structurally very close, due to reduc- tion of the abdomen in Tenagogonus, they can be kept apart at first sight. For our present purpose the actual taxonomic status is not important. Limnometra and Tenagogonus can be distinguished from other SE Asian Gerrinae by the following set of characters (adapted from the key by Andersen 1982): Length less than 25 mm. Pronotum with a dark median stri- pe, venter generally pale. Third segment of rostrum reaching mesosternum. Metasternum without lateral scent channels (from scent orifice to metacetabula), metathoracic spiracle located much more than its own length away from base of fore wing. The difference between Limnometra and Tenagogonus is as follows (adapted from Hungerford & Matsuda 1958): 1. Connexival spines normal, as in fig. 37 (except L. minuta Mayr from Nicobar Islands). Male abdo- men not reduced. Last ventral abdominal seg- ment plus genital segments shorter than preced- ing four segments.

The lateral endosomal sclerites are also pe- culiar in that they are posteriorly broadened and in- cised (fig. 2). The posterior triangular part of prono- tum seems to be somewhat shorter than in the very similar L. insularis Hf. & Mats. We need, however, longer series of fresh specimens of both species to ver- ify whether this is a specific difference or is related to development of indirect flight muscles.

Distribution. — Maluku. The record ‘Celebes; Halmaheira’ by Hungerford & Matsuda (1958) is confusing, as Halmaheira is not on Sulawesi, but one of the islands of Maluku (the Moluccas). Actually there are two records outside Maluku (Hungerford & Matsuda 1958): the type locality ‘Java’ and 2 d 2 9 from ‘Jawa Gunung Gede(h), Frühstorfer’. The label of the type seems to be a mistake of Mayr (1865) as the type series bears labels ‘Amboina, Dr. Doleschal 1859’. Frühstorfer's labels are reported to be quite of- ten incorrect. It is unlikely that this species occurs on Jawa because it should have been collected more of- ten.

Etymology. — Aploos (Greek adjective meaning simple) refers to the lack of striking characters in this species. Comparative notes. — At first sight L. aploa looks like small specimens of L. genitalis sp. n. Apart from the smaller average dimensions, the genital segments and female connexival spines are relatively smaller and middle and hind femur shorter than length of body in L. aploa. L. aploa differs from L. annulicornis Breddin, also known from Sulawesi, by its smaller size, the fourth antennal segment distinctly longer (1.3 X longer than the first (subequal in L. annulicor- nis), the connexival spines in the female pointing dor- sally, and the shape of the endosomal sclerites (figs. 1, 15-16).

NIESER & CHEN: Revision of Limnometra Middle and hind femur slightly longer than body. Etymology. — Genitalis (a latin adjective meaning fertile, marked out to propagate) refers to the large genital segments in male. Ecology. — N89412, N8942 and N8944 are small streams at shaded hilly sites in forests. L. genitalis was found on quiet pools. N8935 is a larger more open stream (over 10m wide), also in forest, with a small artificial waterfall (probably to retain some water dur- ing dry periods). Comparative notes. — This species runs to L. annu- licornis and L. kallisto with the key by Hungerford & Matsuda (1958), but does not seem to be related. The long first genital segment in males and the strongly converging and upward pointing connexival spines in females separate this species from other Limnometra. Limnometra lepta sp. n.

Etymology. — Leptos, a Greek adjective meaning slender, refers to the relatively slender body of this species. Comparative notes. — In the key by Hungerford & Matsuda (1958) this species runs to L. nigripennis, but it is a much more slender species. From other similar species L. lepta differs by characteristics of width of fore femur and leg ciliation as indicated in the key. The apex of the abdomen of the male is very similar to that of L. annulicornis Mayr (Hungerford & Matsuda 1958, pl.15 fig. 26), with which it forms mixed populations in Dumoga Bone National Park. L. annulicornis differs, however, in having a stouter fore femur, middle femur distinctly ciliated and apex of middle and hind femur with distinct light bands. Limnometra melanochroa sp. n.

Hemielytra reaching beyond the apex of abdomen, leaving tips of connexival spines uncovered in both sexes. Etymology. — Melanochroos (a greek adjective meaning dark skinned) refers to the dark general colour compared to other species in the genus. Ecology. — So far only known from altitudes over 1000m apparently in more or less undisturbed forest in SE and Central Sulawesi. Comparative notes. — Due to its dark colour and pale markings on connexiva, L. melanochroa is, at first sight, similar to some species of Aquarius, e.g. À. ven- tralis (Fieber). Closer examination of colour pattern and the position of the metathoracic spiracle, howev- er, assign this species to Limnometra. By its coloration it is not similar to any other Limnometra.

Etymology. — Hysterema, a Greek noun meaning ‘- that what is lacking’, refers to the absence of small peg rows in apical part of middle femur in males of this species. Comparative notes. — Similar to L. annulicornis, L. monochroma and L. arachnis. The latter is much larg- er and more solidly built. All three differ in having one or two short rows of small pegs apically on the middle femur of male and the black setae in basal part of the middle femur not modified. 24 DISCUSSION Although we have not seen all species of the genus, some remarks on species groups can already be made. Limnometra includes several apparently isolated spe- cies, e.g. L. femorata Mayr with aberrant colour pattern, a peculiar midfemoral spur in the male and elongate lateral endosomal sclerites (fig. 5), L. octo- punctata Hungerford with peculiar ventral markings similar to Tenagogonus quinquemaculatus Miyamoto, but not to any species of Limnometra, and an aberrant lateral endosomal sclerite (fig. 9). A further example is L. melanochroa with a colour pattern reminding so- mewhat of L. rossi Hungerford & Matsuda. The latter species falls outside the scope of this paper. It is one of the smallest species in the genus, has lateral endoso- mal sclerites of the L. insularis type, and a relatively more stout build. L. ciliata and L. cursitans form a small group, char- acterised by uniformly coloured antennae and legs and a tendency of having broad dark sublateral bands on the pronotum. Unfortunately we have not seen the male of L. cursitans, so we are unable to comment upon the endosomal sclerites. L. insularis, L. borneensis and L. pseudoinsularis form a group of slender species with a remarkably similar colour pattern, of which the lemon coloured caudolateral margin of the pronotum is striking. In addition, they have rather broad lateral endosomal sclerites without a twisted tip (figs. 2, 6, 44). L. bru- neiensis is associated with this group by its lateral sclerites, but its more solid build reminds of the next group. Finally there is a large group of medium-sized to large species: L. annulicornis, L. arachnis, L. aploa, L. genitalis, L. hysterema, L. kallisto, L. lepta, L. mono- chroma and L. pulchra. They have in common a very uniform general build (except for size) and colour pattern. In addition, the apex of the lateral endosomal sclerites is twisted (figs. 1, 7, 10, 16, 22, 28, 34, 50, 56). This group has so far only been found on Sulawesi where the genus has its highest species diver- sity eastward to the Solomon Islands. Up to now, we have studied two genera, Enithares (Notonectidae) and Limnometra, with several appar- ently closely related species in Sulawesi and Buton. In Enithares we have found four closely related species occurring in Sulawesi and Buton, with restricted ranges. E. horvathi Kirkaldy in SW Sulawesi, E. cae- saries Nsr. & Chen in Central Sulawesi, E. lansburyi Nsr. & Chen in SE Sulawesi and £. skutalis Nsr. & Chen on Buton (Nieser & Chen 1991). In Limnometra we have found in the same area five closely related species, viz. L. annulicornis in N Sulawesi (and ? S Sulawesi), Z. lepta in N and NE Sulawesi, L. aploa in E Sulawesi, L. arachnis in E Sulawesi and on Buton and L. genitalis endemic to Buton. A similar pattern has been found in the gerrid genus Prilomera Amyot & Serville (Polhemus & Polhemus 1986, cited in Whitten et al. 1988). The genus Rhagovelia Mayr (Veliidae) seems to have a more complex distributional pattern in Sulawesi (Polhemus & Polhemus 1988), with a greater num- ber of ecologically separated species in a given area. The actual distributional ranges of the species of the three genera Enithares, Limnometraand Ptilomera show considerable similarity, possibly characterising areas of endemism for aquatic Heteroptera. We sup- pose that the presence of watersheds rather than a his- torical separation of Sulawesi Selatan with slightly higher sea level, was the most important causing fac- tor for speciation in stream-dwelling insects. The lat- ter phenomenon has been used in part for the expla- nation of speciation and subspeciation in macaques (Macaca, Cercopithecidae cited in Whitten et al. 1988), which also have similar distributional pat- terns. At present our knowledge of the distribution of aquatic Heteroptera is insufficient to make further comments. Some of these restricted ranges may ap- pear artificial after more intensive collecting in unex- plored parts of Southwest Sulawesi and the eastern is- lands as Banggai, Sula and Talaud.

Keywords. — Gracillariidae, Caloptilia, Phyllonorycter, Cameraria, new species, Salicaceae, Central Asia, checklist. The Gracillariidae form a large family of leaf-min- ing moths, known from all continents except Antarctica. About 600 species of this family occur in the Palaearctic (Kuznetzov 1981). As far as known, the larvae of most Gracillariidae are leaf-miners of woody and herbaceous angiosperms belonging to 56 families of Dicotyledones (or Magnoliopsida; Takhtajan 1987). Only one species, Spulerina corticicola Kumata, 1964, has been record- ed as a bark-miner of members of Pinaceae (Gymnospermae). The majority of species feed on Fagaceae and Rosaceae (almost 45-50% of the Palaeartic species). Further many species are special- ized on Fabaceae, Betulaceae and Salicaceae. Most species are oligophagous. As an example, all species (except Caloptilia stigmatella (Fabricius)) feeding on Salix and Populus are restricted to Salicaceae. Only C. stigmatella has also been noted in addition on Betulaceae and Myricaceae (Kumata 1982). The study of the Gracillariidae of Central Asia was initiated by Gerasimov (1930, 1931, 1932). He not- ed 13 species from Central Asia, including eight new taxa. Later, one new species was added by Danilevsky: Parornix persicella Danilevsky, 1955 and many more species, including seventeen new species were added due to Kuznetzov’s investigations (1956, 1975, 1978, 1979, 1981, 1985). Furthermore, some papers con- taining faunistic or ecological data on Gracillariidae from Tadzhikistan were published by Sherniyazova (1975, 1982, 1984, 1988). In the course of our own investigations in Tadzhikistan, Turkmeniya, Uzbekistan and southern Kazakhstan from 1986 to 1991, ten species were re- corded for the first time from Central Asia. One of them, Dialectica scalariella (Zeller), had earlier been known from southern Europe, North Africa and the Middle East (Wapshere & Kirk 1977). Eight species were described as new (Noreika 1991; Noreika and Puplesis in press). The gracillarid fauna of the southern part of Central Asia is poorly known. Five species have been found in Iran (Deschka 1979; Triberti 1985, 1986, 1989) and four species are known from Afghanistan. Two species are known from northern Pakistan: Phyllonorycter montanella Bradley, 1980 (Bradley 1980) and Parornix compressa Triberti, 1989 (Triberti 1989). No species are known from Mongolia or the centralasiatic part of China. Most of these species mine leaves of various plant-families: Caprifoliaceae, Rosaceae, Plantaginaceae, Fabaceae, Fagaceae, Betulaceae, Viburnaceae and other ones. As yet, no Salicaceae feeding species have been recorded from these countries. A vegetation type, dominated by Salicaceae, is widespread in Central Asia and forms a characteristic aspect of its vegetation. It is often predominant along rivers and streams, forming a forest type called “Tugai’. As many as ten species out of the 72 species of Gracillariidae known from Central Asia are record- ed as feeding on Salicaceae and apart from one spe- cies, restricted to this family. Only one species, Caloptilia stigmatella (Fabricius, 1781), appears to be disjunct oligophagous, since in other regions this spe- cies has also been noted on Myricaceae and Betulaceae (Kumata 1982).

Scale 1 mm. 28 siatic fauna are the topic of this paper. The treatment of species feeding on related host plants follows a tra- dition in Gracillariidae (compare Kumata 1963, Kuznetzov 1981, Ermolaev 1982, 1988) and is espe- cially useful for diagnostic purposes. However, the polyphyly of such an ‘ecological group’ is evident. MATERIAL AND METHODS Methods for the preparation of the genitalia large- ly follow Falkovitsh & Stekolnikov (1978). The ge- nitalia were studied with the help of a Biolam micro- scope and a MBS-10 stereomicroscope. The material studied has been collected during ex- peditions (from 1986 to 1991) in various regions of Central Asia, including previously unexplored areas (Kugitangtau mountains in eastern Turkmeniya and the valley of Vakhsh in southern Tadzhikistan). In addition, the collection of the Zoological Institute of the Russian Academy of Sciences in St. Petersburg (ZIAS) was studied. In the genera Phyllonorycter and Cameraria the fe- male genitalia are not described, since in these genera they have little diagnostic value, and are rarely used for taxonomy or identification. Locality names are spelled in accordance with the Times Atlas of the World (comprehensive edition 1975 and later). Botanic nomenclature follows Cherepanov (1981) and Takhtajan (1987). Under ‘Material examined” only centralasiatic material is listed. The type specimens of the new species are deposit- ed in the collection of the Minological Research Laboratory of the Zoological Department of the Pedagogical Institute, Vilnius, Lithuania (ver), and in the National Museum of Natural History, Leiden, The Netherlands (RMNH).

In male genitalia, resem- bling Caucasian Ph. armeniella (Kuznetzov), but dif- fering by valva being broader, not bilobed apically, and with horn-like spine, and by longer aedeagus. In male genitalia, Ph. pastorella also closely resembles the Japanese Ph. pulchra (Kumata), which feeds on Rosaceae, but pastorella is easily separeted from this species by its long aedeagus. External characters (fig. 7). — Wingspan 6.7-9.00 mm. Face and labial palpi white. Tuft on head white. Scapus white with tuft of white scales at base. Flagellum shining white. Thorax bright white, some- times with pale ferruginous-brown spot at its centre. Forewing with pale ferruginous-brown and white pat- tern. Basal streak and dorsal streak touching forming together one white spot, which does not reach costa of forewing, with some ferruginous-brown scales al- most at its centre. In medial and apical part of fore- Noreika & PupLesis: Gracillariidae wing, five costal and four dorsal white strigulae; these proximally edged brown or black. First pair of strigu- lae oblique and situated almost at middle of forewing. First costal strigula reaching dorsal strigula, frequent- ly joining each other. Second costal strigula almost equal in width as first costal streak, but shorter. Second costal strigula situated proximal to the tip of the dorsal strigula. Apical three costal and dorsal strig- ulae slightly oblique. Second dorsal is widest among all other strigulae of distal region. Brown-blackish ap- ical spot present. Cilia line at apex of forewing black- ish-brown. Cilia whitish. Hindwing grey cilia whit- ish. Abdomen ferruginous grey, but in distal part yellowish white and laterally whitish. Male genitalia (fig. 18). — Symmetrical. Uncus reaching apex of valva. Vinculum triangular, and shorter than width of valva. Valva simple, broad, and in apical third narrowed, with horn-like spine on apex. Near this spine small cluster of strongly sclero- tized small spines present. Transtilla symmetrical and U-shaped.

Abstracts provided have been arranged per aspect (systematics, ecology). The many indices (classification, taxonomic, species, author, subject, geographical) make this publication a welcome resource for anyone starting a study on ant- arctic invertebrates. The work seems to be compiled carefully and certainly gives many references which cannot be traced easily from abstracting services. Just one remark. The publication is spaciously printed in a unnecessarily large typeface on luxurious paper. | would suggest that an organisation working in area where raw material for the production of paper is vir- tually non-existent, adheres to a more reserved use of paper.

From volume 25 onwards the series Fauna Entomologica Scandinavica is published in the size of Tijdschrift voor Entomologie, also using a two-col- umn format. Although this is certainly an advantage from many points of view, the author will regret that the design of his work, published in at least six parts, has changed for a second time. Descriptions and illus- trations have the same high standard as the previous works of the author. Keys are provided for the genera and the species alike, with separate keys for the apter- ous viviparous females, the alate viviparous females and the oviparous females, whenever needed. Printing as well as contents make this book a valu- able addition to every biological library. [J. van Tol] Hansen, M., 1991. The Hydrophilid Beetles.

[ISSN 0366-3612, ISBN 87-7304-226-9. Price 700 Danish Crowns]. 42 Publication of “The Hydrophilid Beetles’ addresses several long standing problems in the study of this group of insects. Although many papers about Hydrophiloidea were published by authors as d'Orchymont and Balfour-Browne, an overview of the group (146 genera, ca 2400 species) was not avail- able up to now. Furthermore there was no agreement as to the definition of the group as a whole. The paper consists of three major parts: (1) a phy- logenetic analysis of the Hydrophiloidea leading to a reclassification of the group, (2) descriptions of and keys to all genera and suprageneric taxa, (3) a cata- logue of genus- and family-group names of Hydrophiloidea with nomenclatorial details. A detailed comparison of all known hydrophiloid genera has not been published since the description of tropical genera started in the 19th century and was therefore long overdue. Most of the proposed classifi- cations were rather subjective and usually without any argumentation. Hansen's attempt towards a clas- sification based on arguments is a large step forward. The last supraspecific classification for the whole group on a worldwide basis was published in 1924 by Knisch in an issue of the Coleopterorum Catalogus. From that time on numerous new genera were de- scribed and articles treating supraspecific taxa or re- gional faunas published. Newcomers attempting to identify a tropical hydrophilid to at least generic level were convicted to wade through decennia of the ‘Zoological Record’, usually ending with the conclu- sion that the particular group one was looking at was badly in need of revision. The keys, descriptions and figures in Hansen's new book will in most cases en- able an unambiguous identification to genus. For each genus a description, a habitus illustration, the number of species included and the global distribu- tion is given. It is unfortunate that a summary of the distributional data in a biogeographic analysis has not been tried. The extensive catalogue of family and genus group names is especially important. It will most certainly contribute to the nomenclatorial stability of the group. The book is well printed and bound. The quality of the figures is excellent. Separate indexes are provided on species, generic and suprageneric level. This book is a must for everybody who's interest in Hydrophiloidea goes beyond a regional fauna. Besides I recommend it to anybody interested in the general classification of Coleoptera. It may also be useful for ecologists who need to sort samples from more exotic locations. J.

All families except the Rhinophoridae are split into a number of groups, most of which are given subfamilial status, and terminal taxa are scored for a total of 50 characters. Outgroups are Anthomyiidae and Muscidae. The favoured cladogram lists the Sarcophagidae as the sister group of the Tachinidae, the Oestridae as the sister group of the Calliphoridae, and the Rhinophoridae as the sister group of the clade Calliphoridae + Oestridae. The monophyly of all taxa of family rank and above within the Tachinidae family- group is corroborated by explicit listing of apomorphic character states. Implications of various interpretations of character states and transformation series are discussed. Mystacinobia zelandica Holloway, 1976 is accepted as a member of the Tachinidae family- group, but excluded from the analysis because of difficulties in interpreting character state ho- mologies.

Shewell I (1987b: 1162) was of the opinion that ‘biological and NTRODUCTION All recent regional Diptera catalogues (Nearctic: Stone et al. 1965, Neotropical: Papavero 1966-?, Oriental: Delfinado & Hardy 1977, Afrotropical: distributional data suggest [that the Sarcophagidae] are younger than both the Calliphoridae and the Tachinidae’. In strict cladistic terms, this hypothesis implies that Shewell considers the Sarcophagidae to be 43 TIJDSCHRIFT VOOR ENTOMOLOGIE, VOLUME 135, 1992 the sister group of either the Oestridae, the Rhinophoridae, or both — although this actually may not have been the intention. Only McAlpine (1989) has made an attempt of fully resolving the phylogeny at the family level and he considered the clade [Calliphoridae + Mystacinobiidae] + Sarcophagidae as the sister group of the clade Oestridae + [Rhino- phoridae + Tachinidae]. The primary objective of the present paper is to test these hypotheses through reconsideration of available data and incorporation of additional data. In order to be as objective as possible and to facilitate and en- courage future retesting, I have applied a numerical cladistic approach including close to all (non-redun- dant) characters for which I have been able to obtain clearcut scorings. Several characters of potential phy- logenetic value are discussed but not included in the analyses because of my uncertainty with regard to their proper scoring. It is hoped that the detailed an- notations for most characters will serve as the basis for extensive discussions on character (state) interpreta- tion as well as promote a search for additional mor- phological, behavioural and biochemical evidence. The Tachinidae family-group contains the well known blowflies, botflies, flesh flies, tachinid flies, and woodlouse flies. Whether this entire group is giv- en rank of family (Griffiths 1972), family-group (Griffiths 1982) or superfamily (Hennig 1958, McAlpine et al. 1981, Pape 1986a) is of minor con- cern for the present discussion, and I have simply fol- lowed current use of family rank for the subgroups in- cluded. It should be mentioned that the Tachinidae family-group in the present sense equals the Calliphoroidea of Hennig (1958), the Tachinoidea of Rohdendorf (1977) and Pape (1986a), and the Oestroidea of McAlpine et al. (1981). The latter is formally correct in the sense of the International Code on Zoological Nomenclature as the oldest fam- ily-group name within this taxon is based on Oestrus Linnaeus (C.W. Sabrosky, in prep.). Griffiths (1972) used Girschner's (1893) broad definition of the ‘Tachinidae’ for this taxon but later modified the name to the “Tachinidae family-group’ (Griffiths 1982). I have adopted the latter suggestion rather than applying a formal superfamily as I prefer to ap- ply superfamily level much further down the clado- gram of Diptera, as has been done by Griffiths (1972), Crosskey (1980a), Woodley (1989), and Thompson (1990). Furthermore, I prefer “Tachinidae family-group to ‘Oestridae family- group’ as the former is already in use (Griffiths 1982, Thompson 1990), and the latter may easily be mis- interpreted as a group consisting of what is here con- sidered subfamilies of an Oestridae sensu lato, like the Oestroidea of Hackman (1980) or the even more re- stricted Oestroidea of Papavero (1977). 44 Paraphyletic assemblages of families arising when excluding the Tachinidae family-group from more inclusive clades, e. g. from the Calyptratae, are here described as ‘non-tachinoid’, e.g. non-tachinoid cal- yptrates. ‘TERMINOLOGY, METHODS AND CHOICE OF TERMINAL TAXA Terminology is straightforward and follows in ge- neral McAlpine (1981) and Teskey (1981). The only important exception is in the terminology of the structures of the male terminalia, where I have fol- lowed Michelsen (1988) and Wood (1990, 1991). The character matrix (table 2) was analysed with the computer package Hennig86 (version 1.5, copy- right J.S. Farris 1988) on an IBM PS/2-30 (8086 mi- croprocessor). Cladograms (trees) were generated with ‘mh*;bb*;’ rather than any combination of im- plicit enumeration (ie) and branch-swapping (bb). As noted by both Farris (1988: Hennig86 documenta- tion) and Fitzhugh (1989), this includes the possibil- ity of not finding all minimum-length cladograms, but it may be a convenient trade-off as it is consider- ably faster and therefore will allow many more trials. The procedure chosen was judged to have no family- level impact on the resulting equally most parsimoni- ous cladograms, although this hypothesis needs cor- roboration. All character states were treated as unordered when producing a first set of cladograms (changing the Hennig86 default by ‘cc-.;’), and a successive weight- ing procedure (‘xsteps w; in combination with ‘mh*;bb*; and ‘cc; until weights no longer change) was applied to any initial set of equally most parsimo- nious cladograms. The latter procedure, which weights characters according to their best fit to the cladograms concerned through multiplying consis- tency and retention indices and scaling these in the range 0-10, means that clades based on more reliable characters are given higher priority (Fitzhugh 1989). Thus, the resulting cladogram(s) may be different from any of the initial ones. Where successive weight- ing could not reduce the number of equally most par- simonious cladograms to one, a Nelson consensus tree was produced by the ‘nelsen;’ command. As dis- cussed by Carpenter (1988), any of the equally most parsimonious cladograms will represent a stronger hypothesis than the Nelson consensus tree, but I have chosen the latter due to lack of good arguments for selecting amongst these (often numerous) resulting cladograms. Transformation series for characters involving more than two states were deduced from the weight- ed Nelson consensus tree obtained through the proce- dure outlined above. With this new input of phyloge- netic information, data were reanalyzed. The number of characters (here defined as transfor- mation series, see for example Mickevich (1982) and Platnick (1979)) in biological taxa is usually very large, and any phylogenetic analysis can only take a fraction of these into consideration. Exclusion of those characters that would be scored identically for all terminal taxa analysed and thus carry no phyloge- netic information is straightforward. Similarly, those unique (autapomorphic) character states in a given analysis that define terminal taxa may be excluded as well, as they have no impact on the relationships between the taxa. In between is a potentially large number of characters that possess phylogenetic infor- mation in the given context. Of these, some are left unscored simply because they remain unknown to the observer, or because severe problems with regard to interpretation of homology or proper delimitation into states defer clearcut decisions. Therefore, the present data matrix (table 2) contains only those non- redundant characters for which I have been able to obtain ‘reasonably unambiguous’ scorings. In the present analysis, these characters are mostly well known and generally used in descriptive works, but the scorings — which are the heart of the analysis — represent hypotheses that should be tested through more information (morphological, biological, phylo- genetic, etc.) on the terminal taxa considered. All scorings are meant as features of the hypotheti- cal ancestor of the group in question, and I have used ‘groundplan state unknown’ (scored simply as —') whenever a character is inapplicable or when more than one state occurs in a pattern that does not sug- gest one to be a more probable groundplan feature than the other(s). When scoring larger groups one almost always has to deal with exceptions, i.e. one or more species with- in a group showing a character state differing from that of the hypothetical groundplan chosen. Rather than scoring every deviating member separately, which would create an excessive number of terminal taxa; or using ‘state unknown’ for all instances where exceptions were found, which would greatly reduce the amount of information actually at hand, general- izations have sometimes been made. These are dis- cussed in the annotations. Concurrently with the emergence of explicit hypotheses on the basal splits within each of the terminal taxa, these generalizations — and thereby the hypotheses emerging from them — become open to rigorous testing. Two non-tachinoid members of the Calyptratae have been included in the analysis: the Anthomyiidae and the Muscidae. Both families were designated as outgroup relative to the Tachinidae family-group (outgroup = 0.1;’). The Fanniidae are sometimes in- cluded within the Muscidae or considered their sister Pare: Phylogeny of the Tachinidae family-group group, but they are here excluded from the analysis. All Fanniidae have the first anal vein (A, + CuA, or just A,) shortened and may for this reason be consid- ered as members of a group also containing the Muscidae and the Tachinidae family-group. The re- duction of A,, however, is associated with a strongly curved second anal vein (A,), and this feature puts se- rious doubt on the interpretation of the shortening of the first anal vein as homologous to the condition seen in the Muscidae. Pont (1986a: 41) even men- tioned that the Fanniidae ‘may be the primitive sister- group of the rest of the Muscoidea, or even of the Calyptrata’, which finds interesting support in the analysis of ribosomal RNA phylogeny provided by Vossbrinck & Friedman (1989). McAlpine (1989) treated the Fanniidae as the sister group of the Muscidae, but he did not apply a numerical cladistic approach and his hypothesis needs testing by inclu- sion of more data. Non-tachinoid calyptrate phyloge- ny is beyond the purpose of the present paper and I have simply accepted Pont's statement cited above. Anyway, the in- or exclusion of this family in the phy- logenetic analysis presented below would probably have no impact on groundplan estimates for the Tachinidae family-group nor on hypotheses of phylo- genetic relationships between its members. Except for the Rhinophoridae, which have been scored as a terminal taxon, I have split the tachinoid families into a number of subgroups to enhance the corroboration of family groundplan estimates. Note that my use of subfamilial (or tribal) endings should not necessarily be taken as an endorsement of subfa- milial (or tribal) rank for these groups; they are sim- ply more easily referred to as such for the present pur- pose. These subgroups generally equal named and well-known subfamilies or tribes, but a special case is made for the Tachinidae, the subfamilial classifica- tion of which is highly premature in so far as few cur- rently recognized subfamilies emerge as well corrobo- rated monophyletic groups. Crosskey (1980b: 822-823), for example, was of the opinion that the ‘- traditional’ Tachininae ‘almost certainly [are] polyphyletic’. According to Wood (1987c: 1201) ‘the Dexiinae is the only subfamily that can be defined on the basis of a synapomorphy, and Tschorsnig (1985b: 120) stated that the monophyly of the Tachininae as well as the Exoristinae is unsupported (Die Monophylie sowohl der Tachininae als auch der Exoristinae kann nicht begriindet werden’). Still, however, recent suggestions on how to divide the Tachinidae into major subgroups and hypotheses of the phylogenetic relationships between these are al- most exclusively restricted to the traditional concept of the four subfamilies Phasiinae, Exoristinae, Tachininae and Dexiinae (e.g. Shima 1989, Richter 1991) 45 TIJDSCHRIFT VOOR ENTOMOLOGIE, VOLUME 135, 1992 For the present analysis I have applied a much wid- er concept of the Tachininae than the one referred to above, namely by uniting all species which embryo- nate (or are suspected to embryonate) their eggs in the uterus for at least some time after fertilization. This concept was originally proposed by Wood (1985: 8), who regarded the ‘possession of a distensible ovisac for embryonating eggs .... as a synapomorphy of those tachinids that possess it.” I have recognized the Phasiinae as applied by Wood (1987c), and a ‘rest- group’, here named the ‘Exorista genus-group’, in- cluding the non-embryonating, non-phasiine Tachinidae (mainly genera like Aplomya Robineau- Desvoidy, Exorista Meigen, Medina Robineau- Desvoidy, Meigenia Robineau-Desvoidy, Phorocera Robineau-Desvoidy, and Winthemia Robineau- Desvoidy, see Wood (1972, 1985)). This latter group is thus possibly para- or even polyphyletic, but the classification is considered superior to the more tradi- tional division of the Tachinidae into four subfami- lies as the suspected non-group is much less inclusive in terms of genera and species. The Dexiinae will thus be subordinate within the present Tachininae and are not scored separately. The Rhinophoridae need some minor comments. The genus Mimodexia Rohdendorf was described in the Sarcophagidae (Rohdendorf 1935) and later con- sidered a distinct subfamily, Mimodexiinae, of the Calliphoridae with a sister group relationship to the remaining members of this family (Lehrer 1970). Tschorsnig (1985a: 16) proposed Mimodexia as a sen- ior synonym of Callidesia Kugler (Rhinophoridae). The phallus is highly rhinophorid-like and possesses the apical bend of the median sclerotization listed by Pape (1986a) as a synapomorphy for Tromodesia Rondani and Callidesia, and features like wing pat- tern, wing venation, and narrowing of frontal vitta al- so agree with this proposal (Rohdendorf 1935: figs. 79-82, Kugler 1978: figs. 10-11). Thus, I accept the synonymy and thereby the assignment to the Rhinophoridae. Also, I prefer to include the New World Bezzimyia Townsend and the Oriental Malayia Malloch in the Rhinophoridae. Crosskey (1977) discussed the famil- ial assignment of Bezzimyia and considered this genus in the Tachinidae (exclusive of the Rhinophoridae), because ‘the head facies … is conspicuously tachinid, and the enlarged fore tarsi of the female are of the minthoine type’ (p. 13). This was accepted without further comments by Pape (1986a). However, still more evidence is accumulating in favour of an inclu- sion in the Rhinophoridae (Pape, unpubl.). The phal- lus of what appears to be an undescribed species of Bezzimyia (Mexico: Chiapas, El Triunfo, 1 male, 13- 15.v.1985, A. Freidberg, deposited in the Depart- ment of Zoology, University of Tel Aviv) is strikingly 46 similar to the phallus found in the Rhinophoridae (fig. 3), and as subscutellum, lower calypteres and ab- dominal sternite 2 agree more with the Rhinophoridae than with the Tachinidae, I prefer to include Bezzimyia in the former. The rhinophorid ap- pearance may have been the reason why Sabrosky & Arnaud (1965) put Bezzimyia in the Rhinophorinae (as a subfamily of the Tachinidae). Crosskey (1976: 163, 209) listed Malayia as a genus incertae sedis within his possibly polyphyletic Tachininae (i.e. the traditional concept), but also Malayia possesses the rhinophorid-like features here given for Bezzimyia. Admittedly, they do not fit easily into the cladogram of rhinophorid genera produced by Pape (1986a), but lack of evidence does not corroborate anything. Thus, the only argument for treating these rhinophorid-like genera as Tachinidae is that they possess characters not found in any (? other) rhinophorid but which are encountered scattered in the Tachinidae, e.g. a later- ally compressed fore tarsus (many Bezzimyia, some undescribed Malayia), heavily setose facial ridges that are elongated ventrally (Bezzimyia busckii Town- send), or a lobate first flagellomere (some undescribed Bezzimyia). But as long as they cannot be shown to share but a few possibly derived character states with any specific group of Tachinidae, the many apomor- phic character states which are shared with the Rhinophoridae make an affiliation with this family most corroborated. Most probably, the description of either mature eggs or the first instar larvae of Malayia and Bezzimyia — still unknown for both genera — will provide definite clues to their systematic position. Apart from Bezzimyia and Malayia, some other unde- scribed species of Neotropical and Australasian Rhinophoridae have turned up lately (Pape in prep.), and as these do not fit easily in the cladogram of Pape (1986a), the family groundplan remains uncertain for some characters. The lack of a well corroborated infrafamilial clas- sification of the Calliphoridae urges some explanation of the subgroups used. I have treated the Toxotars- inae as including the Sarconesiinae, Kuschelomyinae and Netinae of Lopes & Albuquerque (1982), but distinct from the Chrysomyinae and Rhiniinae, with which they share a row of setae on the posterodorsal surface of the stem vein (remigium). This is not be- cause I endorse subfamily rank for these taxa, but simply because a splitting will bring more detailed scorings and therefore result in better corroborated hypotheses of groundplans and therefore of phyloge- netic relationships. The Auchmeromyiinae of Patton (1935a) [originally spelt Auchmeromyinae] is here widened and synonymized with the Bengaliinae as used by James (1966) and the Bengaliinae and Tricycleinae used by Lehrer (1970). This taxon will probably, in addition to Auchmeromyia Brauer & Bergenstamm and Bengalia Robineau-Desvoidy, con- tain the genera Booponus Aldrich, Cordylobia Grünberg, Hemigymnochaeta Corti, Neocordylobia Villeneuve, Pachychoeromyia Villeneuve, Termi- toloemus Baranov and Tricyclea Wulp, the species of which all are exclusively yellowish or brownish (Rognes 1991, pers. obs.). Moreover, all members may have the spermathecal ducts arranged in the ‘all separate’ configuration (see discussion under charac- ter 25 below), and all genera of this taxon examined by me (Auchmeromyia, Bengalia, Cordylobia, Termitoloemus, Tricyclea) have an elongated first anal vein (A, + CuA,), reaching, or almost reaching the wing margin (see also Villeneuve (1924)). Rognes (1991) mentions that the complete first anal vein is a possible autapomorphy for the Auchmeromyiinae, al- though he simultaneously proposes to maintain the equally equipped genus Bengalia in a subfamily of its own. I know of no character states shared by the non- bengaliine Auchmeromyiinae, which may corrobo- rate their monophyly. A similarity between Auchmeromyia, Cordylobia and Bengalia was, in fact, already noted by Patton (1935a: 229), who men- tioned that ‘practically all the chaetotactic characters lof Auchmeromyia) are common to Bengalia and Cordylobia as well’. The monophyly of the Ameniinae and Mesem- brinellinae, respectively, seems corroborated beyond any doubt (Crosskey 1965, Guimaräes 1977), and the Phumosiinae, including Euphumosia Malloch and Phumosia Robineau-Desvoidy, may be defined by the character states macro- (or uni-) larviparous repro- duction (Ferrar 1978), elongated spermathecae, and the ‘all separate’ configuration of spermathecal ducts. The Helicoboscinae were dealt with by Rognes (1986), with whom I fully agree. Note that already Patton (1939: 107) suggested a calliphorid affiliation of this taxon: ‘It is not possible at present to be certain of the systematic position of Helicobosca muscaria and Helicobosca distinguenda, one point, however, is cer- tain they do not belong to the subfamily Sarcophaginae; the terminalia suggest relationships with the Calliphorinae’. Verves (1990) transferred the genus back into the Paramacronychiinae, but without a detailed discussion on how to explain the absence of the diagnostic sarcophagid groundplan features in this taxon. The subfamilies Calliphorinae, Luciliinae, Mela- nomyinae, and Polleniinae have received a detailed and precise treatment by Rognes (1991) and need no further comment in this context. The subfamilial and tribal phylogeny proposed by Lehrer (1970) will not be thoroughly discussed in the present paper as this author did not explicitly list the (derived) character states defining clades as well as terminal taxa. The Prosthetosomatinae, which were transferred to Pape: Phylogeny of the Tachinidae family-group the Calliphoridae by Pont (1980a), have not been in- cluded as a separate (calliphorid) taxon as they in my opinion represent a group of convenience. The con- stitutive feature is the habit of all members infesting termite nest-mounds (in itself hardly a clearcut char- acter state), and they are known from the larval stag- es only. They will probably fit into one or more of the groups applied in the present paper when adults be- come available. The division of the Sarcophagidae into only three subfamilies has been dealt with by Pape (1987a). Oestridae in the present sense equals that of Wood (1987a), and they have been divided in four subfam- ilies: Cuterebrinae, Gasterophilinae, Hypoder- matinae and Oestrinae. The Gasterophilinae have been further split into two subgroups: Cobboldiini with the genus Cobboldia Brauer on the one hand, and Gasterophilini with Gasterophilus Leach and Gyrostigma Brauer on the other. The systematic posi- tion of the monotypic genera Neocuterebra Grünberg and Ruttenia Rodhain within the Oestridae is uncer- tain (Zumpt 1965; Wood 1986, 1987a), and I have followed the tentative suggestion of Wood (1987a), that they belong to the Cuterebrinae. The monotypic Mystacinobia Holloway from New Zealand has not been included in the analysis, neither as a separate taxon nor by inclusion in one of the ac- cepted taxa. No shared character states have been found which will convincingly indicate inclusion within any of the currently applied families, but I do not consider this justification for a separate family. The strongly autapomorphic morphology renders ho- mologies of most character states highly tentative or even inapplicable, and many scorings are open to se- rious doubt. I prefer to accept Mystacinobia as a mem- ber of the Tachinidae family-group and to treat it as a genus incertae sedis. Possible phylogenetic affinities are discussed further in the section dealing with clades of the Tachinidae family-group. CHARACTERS AND CHARACTER STATES Characters discussed below are given numbers ac- cording to their scorings in the data matrix (table 2), starting with 0 rather than 1 following the procedure of numbering characters in Hennig86 (version 1.5). All characters have been split into two or more states denoted by consecutive numbers (0-n). For the convenience of the later discussion, states have — whe- re possible — been arranged in the transformation se- ries deduced from the initial analysis and with the more plesiomorphic state having the lowest number. Character 0. — Postocular setae; size 0 - equal size, 1 - alternating size, 2 - redu- ced. 47 TIJDSCHRIFT VOOR ENTOMOLOGIE, VOLUME 135, 1992 Apart from Pape (1991), this character has not pre- viously been employed for diagnostic purposes or otherwise explicitly mentioned in connection with the Tachinidae family-group. In the non-tachinoid Calyptratae, the row of postocular setae consists of equal-sized setae or these may increase gradually in size towards the vertex. In the Tachinidae family- group, this row consists of setae distinctly alternating in size, and only two exceptions are known to me: The Oestridae and the Miltogrammatinae (Sarcophagidae). All Oestridae have their general se- tosity greatly modified, with most setae soft and hair- like. The postocular setae are bristly in the sense that they are stiff and tapering, but obviously reduced in length, and they show no alternation in size. As this reduced condition could easily have evolved from any of the other two states, the oestrid condition has been scored as a separate state: reduced (2). In the Miltogrammatinae, species of Macronychia Rondani sometimes have postocular setae slightly alternating in size, but the subfamily has nevertheless been scored for equal sized postocular setae. Character 1. — Postcranium; shape 0 - convex, 1 - concave. The concave condition is found in all Oestridae and in the subfamily Miltogrammatinae of the Sarcophagidae. The groundplan of all other terminal taxa has been scored as convex. Character 2. — Imaginal mouthparts; functionality 0 - fully developed and actively used, 1 - re- duced and never used for feeding purposes. Within the Oestridae, all species possess reduced mouthparts, and only species of Cuterebra Clark and some Hypodermatinae have been seen imbibing wa- ter from wet surfaces (Bennett 1955, Catts & Garcia 1963, Grunin 1965). Solutions of sugar or proteina- ceous substances are never exploited. The non-oestrid taxa have all been scored for fully functional mouth- parts (0) as the very few instances of much reduced mouthparts (e.g. Dexia Meigen and Phasiops Coquillett of the Tachinidae, Chauliooestrus Villeneuve of the Sarcophagidae [not Gasterophilidae as listed) "in: »Pont-"@980b); "see Paper (1991)], Villeneuviella Austen of the Calliphoridae) seem to involve genera far from the basal splits in their respec- tive subfamilies. Character 3. — General integument; coloration 0 - non-metallic, 1 - metallic. The Anthomyiidae and Rhinophoridae possess no members with metallic colours, and the few examples in the Muscidae (eg. Neomyia Walker), Sarcophagidae (only Sarcophaginae, e.g. Sarcophaga metallescens Bezzi, Chlorosarcophaga Townsend), and 48 Tachinidae (e.g. Gymnocheta Robineau-Desvoidy of the Tachininae) may convincingly be characterised as isolated homoplasies by reference to what is known of infrafamilial phylogeny in these groups. In the sub- family Cuterebrinae, metallic colours occur in Neocuterebra squamosa Griinberg and Dermatobia hominis (Linnaeus, Jr). Members of the genus Cuterebra sensu lato generally have a shining integu- ment and a few species present a distinct metallic tinge, e.g. Cuterebra atrox Clark. Ruttenia loxodontis Rodhain has no metallic coloration. The groundplan of the Cuterebrinae has been scored as unknown with regard to this character. Metallic colours are not present in the Gasterophilini. In Cobboldia, the Afrotropical species C. loxodontis Brauer and C. roverei Gedoelst have tho- rax and abdomen metallic blue and green respective- ly, but the Oriental C. elephantis (Cobbold) is non- metallic. In the Calliphoridae, no member of the Helicoboscinae and the Bengaliinae possess a metallic coloured integument, and these have accordingly been scored as non-metallic (0). In the Polleniinae, metallic colours are generally absent but at least some New Zealand Pollenia Robineau-Desvoidy are metal- lic green (Dear 1986). The ‘Australasian’ concept of this genus, however, is much broader than that con- taining only those Palearctic species with soft, yellow- ish, crinkled hairs amongst the thoracic setae, and as I have been unable to differentiate Pollenia (s.1.) from the remaining genera of Polleniinae, the groundplan of the subfamily has been scored as unknown for this character. Also, several species of Rhiniinae and Melanomya Rondani of Melanomyinae are non-me- tallic and the groundplan of these subfamilies has been scored as unknown for this character. Remaining calliphorid subfamilies have been scored as metallic (1). Character 4. — Imago; clothing setae 0 - unmodified setae, 1 - most setae hairli- ke. The hairy condition of all members of the oestrid subfamilies is well known and needs no further com- ment. Rhyncomya Robineau-Desvoidy (Rhiniinae) and Palearctic Pollenia (Polleniinae) of the Calliphoridae possess whitish or yellowish hairs among the setae, but never to a degree comparable with any botfly, and the hairs are crinkled and unlike those found in the Oestridae. Character 5. — Prosternum; setosity 0 - bare, 1 - setose. In the Sarcophagidae, most members of subfamily Sarcophaginae have the prosternum setose and the groundplan has been scored as such. No Paramacronychiinae and in the Miltogrammatinae only Chrysogramma Rohdendorf (preocc., no valid name at present) have setae on this sclerite. No Rhiniinae and Polleniinae have a setose prosternum, while the setose condition is widespread in all other terminal taxa of Oestridae and Calliphoridae. In the Tachinidae, I have not seen the setose condition in the Phasiinae nor in the Exorista genus-group, but both conditions occur in the Tachininae, and the groundplan of the latter has been scored as unknown for this character. Character 6. — Proanepisternum; setosity 0 - bare, 1 - setose. A setose proanepisternum (upper, depressed part of propleuron) may be found scattered throughout the Sarcophagidae, but always in distinct clades that are not engaged in the basal dichotomies of their respec- tive subfamilies. Therefore, I feel confident by scoring the groundplan of the contained subfamilies as bare (0). In the Calliphoridae, I have found no instances of a setose proanepisternum in the Mesembrinellinae, Polleniinae and Rhiniinae — all scored as bare (0) — while both states occur in the Bengaliinae (setose in Tricyclea, bare in others) and Melanomyinae (bare in Melanomya, setose in Melinda Robineau-Desvoidy), which have been scored as unknown. Remaining cal- liphorid subfamilies have been scored as setose (1) as I know of no exceptions. No Rhinophoridae possess a setose proanepisternum, and in the Tachinidae no members of the Phasiinae and the Exorista genus- group seen by me have this surface setose. Both con- ditions occur in the Tachininae, the groundplan of which accordingly has been scored as unknown. The Oestridae probably have the setose condition as a groundplan feature. In the Cuterebrinae the proane- pisternum is bare in Neocuterebraand Ruttenia, setose in Dermatobia Brauer and Cuterebra. Gasterophilus, Gyrostigma and Cobboldia of the Gasterophilinae all possess a setose proanepisternum. In the Hypodermatinae, the setose condition is found in Oestromyia Brauer, but only occasionally in the Hypodermatini. No Oestrinae possess a setose proan- episternum. Character 7. — Postalar wall; setosity 0 - bare, 1 - setose. The typical pattern of postalar setae is an isolated tuft of setae centrally on the postalar wall. Several genera of the sarcophagid subfamily Sarcophaginae possess postalar setae in this configuration, but no postalar setae are found in the genus Tricharaea Thomson, which is often considered close to the ba- sal split(s) of this taxon, and the sarcophagine groundplan has been scored as unknown. No mem- bers of the Paramacronychiinae possess postalar setae, Pape: Phylogeny of the Tachinidae family-group and where a few postalar setae occur in the Milto- grammatinae, e.g. Metopia brasiliana Townsend (Pape 1987), these are probably homoplasic as prob- ably basal groups like Macronychia and Eumacronychia Townsend do not possess any postalar setae. Both conditions are found in the Melanomyinae (bare in Melanomya, setose in Melinda), but of general occurrence in the other calli- phorid subfamilies, which have been scored as setose (1). The oestrid taxa have been scored as setose (1), al- though apparently bare conditions occur in the Oestrinae, e.g. in Tracheomyia macropi (Frogatt) and in some Gasterophilus spp. These exceptions all pos- sess setae higher up on the postalar wall which are confluent with the general setosity of notum, but I have not been able to decide whether this setosity is homologous to true postalar setae. I have not found any Tachinidae with a setose postalar wall and the three subgroups here recognized have been scored as bare (0). Character 8. — Metasternum; setosity 0 - bare, 1 - setose. Note that what is here called metasternum (i.e. the convex sclerite situated in front of the hind trochant- ers) probably includes pleural elements, and the metasternum proper is largely invaginated. I have found no Anthomyiidae, Muscidae, Rhinophoridae or Tachinidae with a setose metasternum. In the Sarcophagidae metasternal setosity is present in all Sarcophaginae, absent in Paramacronychiinae, and in the Miltogrammatinae only present in Chryso- gramma. All Oestridae seen by me have the metaster- num setose. The calliphorid subfamilies have been scored as setose (1) as the few exceptions, e.g. some but not all Melanomya, are considered as derived from the setose condition. Character 9. — Meron; setosity 0 - bare, 1 - with a vertical row of bristles, 2 - with a patch or tuft of hairs. Usually, the row of meral bristles runs vertically at the posterior margin of the sclerite and may follow this where it curves forwards along the anteroventral margin of the metathoracic spiracle. Smaller species may have the number of bristles reduced to 2-3, e.g. many Rhinophoridae and small Tachinidae, while larger species often have numerous additional hair- like setae, especially anterior to the bristles. Very few Tachininae, e.g. the genera Tarassus Aldrich (Neotropical) and Lophosiosoma Mesnil (Oriental), lack meral bristles altogether, but these are considered reversals and the groundplan of the Tachininae has been scored as 1. Rognes (1986) considered the mer- al hairs found in the Oestridae as non-homologous to the meral bristles of the remaining Tachinidae family- 49 TIJDSCHRIFT VOOR ENTOMOLOGIE, VOLUME 135, 1992 group, possibly because the hairs usually form a patch rather than a vertical row. In my opinion, the identi- cal position compared to that of the bristly row of the non-oestrid members of the Tachinidae family-group should be taken as a priori evidence of homology. The hairlike appearance of the meral setae is most parsi- moniously regarded as part of the general hairiness, and it should be noted that the meral hairs sometimes are developed as a row of fine bristles, e.g. in Dermatobia hominis (Cuterebrinae) (Wood 1987a, pers. observation). Sabrosky (1986: 40) noted that Cuterebra has the meron equipped with ‘a tuft of stiff, bristly, black hairs in most species’. Meral setae are also found in non-tachinoid Calyptratae, especially well developed in the genus Eginia Robineau-Desvoidy (Muscidae) but also in more typical Muscidae (Pont 1986b, McAlpine 1989). A few Anthomyiidae possess meral setae, e.g. Eutrichota Kowarz (Huckett 1987) and ‘McAlpine’s fly’ (pers. obs.), which tentatively has been assigned to the Anthomyiidae (Ferrar 1979, 1987). Only in Eginia, however, is the configuration reminiscent ofa (very short) vertical row of long and bristly setae. Pont (1977) placed Eginia with some related genera in their own family, Eginiidae, but later transferred the group to the subfamily Phaoniinae of the Muscidae (Pont 1986b, as Eginiini). Skidmore (1985) was convinced that Eginiini did not belong in the Muscidae and he suggested affinities to be with the Tachinidae or the Calliphoridae. This decision, however, was primarily based on the presence of well developed parastomal bars in the cephalopharyngeal skeleton of what was thought to be a puparium of Eginia ocypterata (Meigen). As this puparium seems to belong to the Sciomyzidae (V. Michelsen, pers. comm.), the evidence for excluding Eginiini from the Muscidae is strongly reduced. A discussion of the systematic position of Eginiini is given by McAlpine (1989: 1498). Character 10. — Subscutellum, shape 0 - concave, 1 - slightly swollen, 2 - strong- ly swollen. The concave condition found in all Anthomyiidae and Muscidae examined by me is easily distinguished from the swollen conditions (1, 2). A similar concave condition is found in the three sarcophagid subfami- lies except in Nyctia Robineau-Desvoidy of the Paramacronychiinae where the slightly swollen con- dition obviously has evolved independently. The ta- chinid taxa are here scored for the strongly swollen condition (2), although some exceptions occur, e.g. Cinochira Zetterstedt and Cylindromyiella Malloch. Crosskey (1976: 36), however, noted that it ‘is not completely certain that Cylindromyiella is a tachinid’. Downes (1986) considered the groundplan of the 50 Tachinidae to be characterised by a medium-sized subscutellum, which led him to assume that ‘the sub- scutellum has become enlarged independently in more than one lineage’ (p. 15) within the family. In my opinion, it is more parsimonious to consider the strongly swollen subscutellum of the Tachinidae as a groundplan feature. Within the Oestridae, the subscutellum of the Cuterebrinae (Wood 1987a: fig. 9) and Gasterophilinae is considered as state 1, while the subscutellum of the Hypodermatinae (Wood 1987a: fig. 10) is distinctly larger and is scored as such (2). In the Oestrinae, Oestrus has a strongly swollen subscu- tellum but other states occur, like the almost concave subscutellum of Cephenemyia Latreille and Pharyngomyia Schiner (Zumpt 1965). The subscutel- lar groundplan of the Oestrinae has accordingly been scored as unknown. All Rhinophoridae have a slightly swollen subscu- tellum (Wood 1987b: figs. 2,3), and so have the cal- liphorid subfamilies Ameniinae, Bengaliinae, Helicoboscinae, Mesembrinellinae and Polleniinae, which all possess a subscutellum that definitely is con- vex, but still much less swollen than the condition in the Tachinidae. As both the concave and the slightly swollen conditions occur in the Melanomyinae, this taxon has been scored as unknown for this character. As an intermediate condition, the slightly swollen condition is poorly defined. More precise morpho- logical descriptive terms will probably increase the number of states and add important phylogenetic in- formation. Character 11. — Anatergite; setosity 0 - bare, 1 - setulose. If present, the laterotergal ‘hairs or setae of McAlpine (1989: 1498) [= infrasquamal setulae of Shewell (1987b: fig. 108.23)] are arranged in a small patch or cluster on the anatergite just below the low- er calypter. I have not found infrasquamal setulae in any Anthomyiidae, and in the Muscidae only in Neomyia, and I have scored the groundplan of both families as bare (0). All Calliphoridae, Rhinophoridae and Tachinidae seem to possess infrasquamal setulae (I have, however, seen some specimens of the rhino- phorid Paykullia kugleri (Herting) with few and even no setulae). Among the Sarcophagidae, all species of Paramacronychiinae and Sarcophaginae have infra- squamal setulae, but the large majority of Miltogrammatinae have the anatergite completely bare. Some exceptions, however, occur, e.g. Eumacronychia and Macronychia, and occasional specimens of Xiphidiella Villeneuve, and I have scored the miltogrammatine groundplan as unknown for this character. No Oestridae possess anatergal set- ulae. Character 12. — Metathoracic spiracle; configuration of fringe 0 - continuous along posterior, ventral and anterior rim, 1 - divided into an anterior and a posterior fringe. The Muscidae and the Anthomyiidae are scored for a continuous fringe, although this fringe often is dis- tinctly thinned ventrally. Within the Tachinidae fam- ily-group, I know of only the following exceptions from the divided fringe: Mystacinobia, which is dis- cussed separately below, has no fringe at all. The Mesembrinellinae were given family rank by Guimaräes (1977), probably prompted by Crosskey's (1965: 43) statement that they ‘may not be Tachinoidea at all’. Their metathoracic spiracle devi- ates strongly from that of other Calliphoridae in be- ing equipped with a large continuous fringe, much like some Muscidae (e.g. Phaonia Robineau- Desvoidy). Bequaertiana Curran of the Rhinophoridae has almost no fringe, which added to Zumpt's (1956) conviction that this genus was an acalyptrate. The generic cladogram of Pape (1986a), however, suggests that the spiracular configuration of Bequaertiana is apomorphic. Groundplan estimates of the Oestridae are difficult as much variation oc- curs. In the Cuterebrinae, Neocuterebra and Ruttenia have a continuous fringe, all Cuterebra a divided fringe. In the Gasterophilinae species of Cobboldia have a divided fringe, those of Gasterophilus and Gyrostigma have a continuous fringe. All Hypodermatinae have a continuous fringe while all Oestrinae have a divided fringe. Several small Tachinidae and Calliphoridae (e.g. Cinochira, some Melanomya), and all of Rhinophoridae have small metathoracic spiracles, but they still provide good examples of the divided condi- tion. From the SEM figures given by Crosskey (1977: figs. 41-44), it may be observed that Melanophora roralis (Linnaeus), Phyto discrepans Pandellé and Stevenia atramentaria (Meigen) possess distinctly di- vided metathoracic fringes, and only the fringe seen in Rhinophora lepida (Meigen) could perhaps be tak- en for continuous, although even here a distinct break of the fringe can be observed ventrally (which is al- most to the right in Crosskey's figure). Character 13. - Metathoracic spiracle; relative size of anterior and posterior lappets 0 - both lappets small, 1 - narrow anterior lappet and large posterior lappet, 2 - both lappets large. This attempt of fitting the configurational multi- tude of metathoracic spiracular lappets into a few states based on relative size alone may seem too sim- ple as ‘a wide range of “opercular” metathoracic spir- acles occurs in Tachinidae-Calliphoridae-Sarco- Pare: Phylogeny of the Tachinidae family-group phagidae’ (Crosskey 1977: 8). On the other hand, scoring most types of fringe configurations different- ly would cause an extreme splitting of taxa that would be difficult (and very time-consuming) to score at the present state of knowledge — and actually carry less phylogenetic information as far as interfamilial rela- tionships are concerned. Therefore, I have tried to re- duce the number of groundplan types, and the present three-state character seems in agreement with Crosskey (1977: 8), as his ‘representative[s] of two very common types’ fit my states 1 and 2 perfectly. The Helicoboscinae, all Oestridae except those with continuous fringe, and the sarcophagid and ta- chinid taxa are scored for state 1 where the spiracular fringe is divided into a narrow, crescent-shaped ante- rior fringe (or lappet) and a broad, operculum-like posterior lappet that is often distinctly narrowed at base (Crosskey 1977: fig. 45; Rognes 1986: fig. 3). Rarely, the two lappets are more equal to each other, as in the genera Macronychia (Miltogrammatinae) and Chrysotachina Brauer & Bergenstamm (Tachininae) (Wood 1987c: fig. 169), a configuration which I con- sider as apomorphic for these genera. Anthomyiidae, Muscidae, Mesembrinellinae, Gasterophilus + Gyros- tigma in the Gasterophilinae, and Hypodermatinae have been scored as inapplicable for this character as they possess a continuous fringe. In many Calliphoridae, the anterior lappet is en- larged. Rarely it is very much larger than the opercu- lum, as in the genus Phumosia (Calliphoridae) depict- ed by Crosskey (1977: fig. 46), but note that this figure is of the right metathoracic spiracle, contrary to all other spiracles figured. I have scored all non-helic- oboscine calliphorid subfamilies for an enlarged ante- rior lappet (2) although exceptions occur, e.g. some Melanomya in the Melanomyinae. Species with a small metathoracic spiracle, e.g. all Rhinophoridae, often have a reduced and less operculum-like posteri- or lappet, and this condition is here considered a dis- tinct state (0). Downes (1986), Pape (1986a) and Rognes (1986) all mention more or less explicitly that a large meta- thoracic spiracle is characteristic for (part of) the Calliphoridae, and Downes (1986: 19) stated that he considered the enlarged metathoracic spiracle to have developed several times in that family: “The Calliphoridae have repeatedly developed very large posterior thoracic spiracles that intrude forward into the hind margin of the meron.’ Apparently, the spi- racular fringe has enlarged as well, and the large ma- jority of species in all non-helicoboscine calliphorid subfamilies show this state with unambiguous clarity. Rognes (1991) provides many line-drawings of calli- phorid metathoracic spiracles. The Helicoboscinae, on the other hand, is a perfect representative of the ‘narrow/large’ condition (1), see Rognes (1986: fig. 51 TIJDSCHRIFT VOOR ENTOMOLOGIE, VOLUME 135, 1992 3). The subfamily Ameniinae was for long considered in the Tachinidae, but Crosskey (1965) convincingly transferred them to the Calliphoridae, although not- ing that ‘the Ameniinae [may be] as closely related to the Sarcophagidae as to the Calliphoridae’ and that ‘it may be better to treat [them] as a full family’ (p. 43). The metathoracic spiracular fringe of most species is perfectly ‘large/large’ (2) and I have all reasons to con- sider this as homologous to the condition found in other non-helicoboscine calliphorid subfamilies. The few calliphorid species with a rhinophorid-like meta- thoracic spiracle fall nicely within their respective taxa through their close affinity with more typical calli- phorids, like the close relationship between the genus Melinda and the Melanomya genus-group (Rognes 1986, 1991). All species of Mesembrinellinae possess a metatho- racic spiracle with one continuous, large fringe (Guimaraes 1977: fig. 8). This non-opercular condi- tion brings some problems of homology, i.e. whether all of the fringe or only the anterior part is homolo- gous to the anterior lappet of other Calliphoridae. Accordingly, this character has been scored as inappli- cable for the Mesembrinellinae. The shape of the rhinophorid metathoracic spirac- ular fringe needs special mention as this could be con- sidered intermediate between the operculate fringe found in Calliphoridae, Oestridae, Tachinidae and Sarcophagidae on the one side and the type with a continuous fringe found in the non-tachinoid calyp- trates on the other. Note, however, that an operculate metathoracic spiracle occurs in the rhinophorid genus Baniassa Kugler, where it may be considered a rever- sal, i.e. apomorphic (Pape 1986a). Crosskey (1977: 8) made the following description of the rhinophorid spiracle: ‘In Rhinophoridae .... the external opening of the spiracle lacks a definite occluding flap or pair of flaps and instead is margined by complex short fring- es that stand out from the spiracular rim (there being normally an anterior and a posterior fringe that meet ventrally but that are widely separated dorsally),’ and he considered ‘the nature of the metathoracic spiracle [as providing] the most important single character for rhinophorid recognition’. McAlpine (1989: 1501) characterised the rhinophorid spiracle as ‘subcircular, without distinct operculum, and margined with erect fringe of hairs’ and considered this an ‘important plesiomorphic character’. I have no 4 priori reason to do this, and McAlpine was, in fact, contradicted by his own cladogram (fig. 116.8). Both outgroups, i.e. Muscidae and Anthomyiidae, have been scored as unknown/inapplicable for this character. I have insufficient knowledge of the meta- thoracic spiracular groundplan for these two families, and the continuous nature of the fringe would make any scoring rather tentative. 52 Character 14. — Anepimeron; setosity 0 - bare, 1 - setose. Anepimeral setae occur in only a few Anthomyiidae (Huckett 1987) and Muscidae (Huckett & Vockeroth 1987), but in all members of the Tachinidae family-group. Also, while bristly ane- pimeral setae are virtually absent in the Anthomyiidae and Muscidae, they are widespread and common in the Tachinidae family-group. Therefore, the present scoring of the anthomyiid and muscid anepimeral groundplan as bare (0) and that of all other taxa as se- tose (1), seems well founded. Character 15. — Wing vein M; course distal to cross- vein dm-cu 0 - bent anteriorly at junction with dm-cu, 1 - a straight (or at least non-bent) conti- nuation of proximal part, 2 - bent anterior- ly at a more or less right angle, with bend distinctly removed from dm-cu, 3 - bent anteriorly at an obtuse angle, with bend distinctly removed from dm-cu. Gasterophilus + Gyrostigma (Gasterophilini) show the straight condition (1), while species of Cobboldia as well as all Cuterebrinae and Oestrinae show the sharply bent condition (2). The Hypodermatinae are unique in having the bend occurring almost exactly at junction between M and crossvein dm-cu. The ob- tuse angle or gentle curve of M (state 3) is found in the Mesembrinellinae (Calliphoridae) and Rhinophoridae. This state is also found in many smaller species of Calliphoridae (e.g. some Melanomya), while some Tachinidae (e.g. Freraea Robineau-Desvoidy, Cinochira, Cylindromyiella) have the bend almost absent. These instances are here con- sidered independent acquisitions derived from the bent conditions. The total absence of the distal part in various Tachinidae, and in Bezzimyia, Bequaertiana, Melanophora asetosa Kugler and Oplisa aterrima (Strobl) of the Rhinophoridae is obviously a distinct state. No evidence, however, suggests that this state may characterise the groundplan of any of the taxa scored in the present analysis, and I have not made a special entry. Note that some species of Phyto Robineau-Desvoidy, e.g. P. armadillonis Kugler, and Mimodexia spp. show a vein M with a bend that is very reminiscent of the condition found in most Calliphoridae, i.e. bent in an almost right angle (Rohdendorf 1935: fig. 82; Kugler 1978: figs. 11, 26). These species, however, do not seem to be close to the basal splits within the family and their venation is accordingly more parsimoniously regarded as ho- moplasic. No Anthomyiidae possess a bent vein M, but in the Muscidae many Muscinae have this vein distinctly bent. However, as no other Muscidae to my know- ledge share this condition, it is not considered a groundplan state of the family. Character 16. — Wing vein Sc; course 0 - with a convexity at level of humeral break, 1 - straight at level of humeral break. As noted by Herting (1955), vein Sc of all Oestridae takes a parallel course relative to the costa until it bends towards it, ultimately reaching the wing margin (Wood 1987a: figs. 5-8). In the Muscidae and the Anthomyiidae and the non-oestrid members of the Tachinidae family-group, this vein has a distinct- ly convex part (relative to the anterior wing margin) at level of, or just distal to the humeral break (McAlpine 1981: fig. 69). Character 17. — Wing vein R,; configuration at level of subcostal break 0 - with a knob, 1 - without a knob. In most Calyptratae, and certainly in the non-oes- trid taxa included in the present analysis, vein R, has a small knob on the anterior surface at the level where subcosta bends towards costa. This has been taken as vestiges of a crossvein (sc-r) connecting subcostal and radial veins (McAlpine 1981). All botflies examined by me lack this knob of R,. Character 18. — Posterodorsal surface of stem vein (remigium); setosity 0 - bare, 1 - setulose. To my knowledge, all members of Chrysomyinae, Rhiniinae and Toxotarsinae possess the setose condi- tion (1). Only two other occurrences of a setose remi- gium are known within the Tachinidae family-group: in two species of Mesembrinellinae, Mesembrinella bellardiana Aldrich and M. peregrina Aldrich, and in Pollenia atramentaria (Meigen) of the Polleniinae. As P. atramentaria does not seem to be the sister group of all remaining Polleniinae, I have scored the groundplan of this subfamily for a bare remigium (0). The groundplan of the Mesembrinellinae, however, has been scored as unknown for this character as the genus Mesembrinella Giglio-Tos seems to be defined exclusively on the possession of three (instead of two) humeral bristles (Guimaräes 1977), which probably is plesiomorphic at this level. Thus, I cannot exclude that M. bellardiana and M. peregrina are included in the basal dichotomy of this subfamily. Character 19. — First anal vein; length relative to wing margin 0 - extending to or almost to wing margin, 1 - reduced and ending in wing membrane distinctly before wing margin. I have not seen any Muscidae, except for members of the Eginiini, with an extended A,, and Huckett & Pape: Phylogeny of the Tachinidae family-group Vockeroth (1987: 1116) stated that for the Nearctic Muscidae this vein is ‘always incomplete’. As already mentioned, I have accepted the inclusion of Eginiini within the subfamily Phaoniinae of the Muscidae, and the groundplan of the family has been scored as reduced (1) for the present character. In the Anthomyiidae very few genera, Acridomyia Stackelberg and Coenosopsia Malloch, have a reduced first anal vein, but as there is no reason to consider these genera close to each other and neither as sister group of the remaining Anthomyiidae (V. Michelsen, pers. comm.), the reduction is probably derived inde- pendently. The family has accordingly been scored for an extended first anal vein (0). In the Tachinidae family-group all members of Bengaliinae and Gasterophilini possess an extended first anal vein. In the Cuterebrinae Neocuterebra possess an extended first anal vein, but as all other species have a distinct- ly shortened vein the groundplan of this subfamily has been scored as unknown. A few genera in the Tachininae (e.g. Siphona Meigen) and Rhinophoridae (Malayia) show the extended condi- tion. These instances are all considered as derived. Character 20. — Base of vein R,.; setosity 0 - bare, 1 - setulose. The large majority of species within the Tachinidae family-group possess some setulae on the upper sur- face of the base of vein R,.., either as a few setulae at the very base (actually the common base of R,., and R,,,) or as a distinct row along the vein. Usually, set- ulae are present on the lower surface as well. In the Cuterebrinae, the base of R,.. is setose in Dermatobia hominisand the Cuterebra examined by me, while it is bare in Neocuterebra and Ruttenia. Gyrostigma + Gasterophilus of the Gasterophilini show the bare condition, Cobboldia the setose. All Oestrinae seen possess the setose condition, while both conditions occur in the Hypodermatinae. In the Polleniinae, all species of Morinia Robineau-Desvoidy and Melanodexia Williston have this vein bare while it is setulose in Pollenia. The Polleniinae has therefore been scored as unknown for this character, although the absence most probably is apomorphic for Morinia + Melanodexia, as already noted by Rognes (1991: 209). The only other instance of a bare base of vein R,,, within the Tachinidae family-group known to me is in the Phyto carinata species-group of the Rhinophoridae (Pape 1987b), but several others may occur. À setulose base of vein R,,, occurs sporadically in the Muscidae, e.g. species of Graphomya Robineau-Desvoidy, Musca Linnaeus, Neomyia, and Stomoxys Geoffroy (Huckett & Vockeroth 1987: figs. 21-30, Zumpt 1973: fig. 94), but not in Achanthiptera rohrelliformis (Robineau-Desvoidy), the sole member of subfamily Achanthipterinae. 53 TIJDSCHRIFT VOOR ENTOMOLOGIE, VOLUME 135, 1992 Achanthiptera Rondani has abdominal spiracle 6 re- tained in the female terminalia and has for this reason been considered as one branch of the basal dichotomy of the family (Carvalho 1989). Huckett & Vockeroth (1987: 1117), however, found the female abdominal spiracle 6 retained ‘in a few exotic species of several subfamilies’, which weakens the argument that Achanthiptera should be considered a basal lineage. Awaiting more knowledge of muscid phylogeny, I have scored the groundplan as unknown for this char- acter. I have not seen any Anthomyiidae showing the setose condition. Character 21. — Lower calypter; shape 0 - narrow, 1 - oval, 2 - broad, 3 - tongue- shaped. With the convincing exclusion of Melanomya (here including Angioneura Brauer & Bergenstamm) from the Rhinophoridae presented by Downes (1986), Rognes (1986, 1991) and Pape (1986a), all Rhinophoridae possess a lower calypter, which is bigger than the upper calypter, diverging from the scutellum, and either slightly roundish or parallel-sid- ed for part of its length (3). Species of the Rhiniinae possess a very rhinophorid-like lower calypter and have been scored similarly (3), while both the broad and tongue-shaped conditions occur in the Chrysomyinae (broad in Chrysomya Robineau- Desvoidy, tongue-shaped in all others), and the groundplan of this subfamily has been scored as un- known. The Anthomyiidae are scored for the widespread narrow state (0), where the lower calypter does not exceed the upper calypter in size. However, examples occur where the lower calypter is subequal to or even exceed the upper calypter in length (Huckett 1987), and the character needs reconsideration. The Muscidae are difficult to score as numerous states oc- cur, ranging from the rather short type found in Achanthiptera rohrelliformis with a posterior margin running almost perpendicular to the median plane, to lower calypteres fully as large and broad as those of the Tachinidae family-group. The oval type of the Muscidae (Huckett & Vockeroth 1987: fig. 15), which is smaller and slightly more tapering than the condition found in the Rhinophoridae, seems to be most widespread (and incidentally also the most com- mon) and is here postulated as groundplan. Further knowledge of muscid infrafamilial phylogeny is need- ed. The groundplan of all other terminal taxa seems to be characterised by the broad type with the median margin following scutellum for a considerable dis- tance before turning outwards almost perpendicular to the median plane. The several non-rhinophorid and non-rhiniine taxa of the Tachinidae family-group 54 with diverging lower calypteres, e.g. Cinochira and Cylindromyiella (Tachinidae: Phasiinae), some species of Johnsonia Coquillett and Neophyto Townsend (Sar- cophagidae: Sarcophaginae), Morinia (Calliphoridae: Polleniinae), and . Melanomya (Calliphoridae: Melanomyinae) are easily classified as derived from the broad condition by simple outgroup comparison within their respective subfamilies. Morinia, for ex- ample, may be the sister group of Melanodexia (cor- roborated by black body colour and absence of setae on wing vein R,..), and the tongue-shaped condition in Morinia is therefore most parsimoniously consid- ered apomorphic at this level as Melanodexia and all other Polleniinae have broad lower calypteres. Likewise, if it is accepted that the Miltogrammatinae are the sister group of a monophyletic Para- macronychiinae + Sarcophaginae (Kurahashi 1975; Pape 1986b, 1987a; present analysis), the presence of broad lower calypteres in all species of both non-sar- cophagine subfamilies is convincing evidence that the possession of narrow lower calypteres in Johnsonia and Neophyto is apomorhic. Downes (1986), howev- er, takes the opposite standpoint and argues from a functional viewpoint. Broad lower calypteres are seen as independent adaptations to increase flight speed and agility, and the ‘primitive-looking groups are considered as having been ‘shunted off from the mainstream of calyptrate evolution’ (p. 17). Species of the Tachinidae family-group are generally very ag- ile flyers compared to most Muscidae and Anthomyiidae, and this may indeed be correlated with the size of the lower calypteres. Flight patterns, however, are the functional manifestations of mor- phological and physiological character states and are thus obviously subject to reversals and homoplasy. I see no reason or argument for postulating a main- stream calyptrate evolution. It is more parsimonious, i.e. requires less ad hoc assumptions, to consider the shape of calypteres in Neophyto, Johnsonia and the Rhinophoridae as independent evolutionary events. Character 22. — Abdominal sternite 2; degree of exposition 0 - freely exposed but only separated from margins of tergite 1+2 by a narrow strip of unfolded membrane, 1 - contiguous with or slightly overlapped by margins of tergite 1+2, 2 - completely overlapped by margins of tergite 1+2, 3 - overlapping margins of tergite 1+2, 4 - freely exposed and widely separated from tergal margins by more or less folded membrane. The degree of exposition of the non-terminal ab- dominal sternites is a character of diagnostic value, but I have focused on sternite 2 rather than all of ster- nites 2-5 as this may be the easiest to score. The Sarcophagidae are very homogenous, with abdominal sternite 2 distinctly overlapping margins of corre- sponding (syn)tergite in all but the aberrant and obvi- ously apomorphic Asilodexia Townsend (Sar- cophaginae). The Calliphoridae are more varied, from a perfectly muscid-like condition in the Mesembrinellinae to a rhinophorid-like condition in some Melanomya, the Helicoboscinae, and the Ameniinae. The configuration in the Rhinophoridae is here scored like the Ameniinae and Helicoboscinae (1) as I have no a priori reason to consider them non- homologous. The Phasiinae have been scored like the Rhinophoridae, although exceptions occur. Character 23. - Alpha setae; presence/absence 0 - present, 1 - absent. Alpha setae (sensilla trichodia) are found wide- spread in most Rhinophoridae and scattered in the Tachinidae (Lehrer 1973, Tschorsnig 1985b). They are absent from the Ameniinae (Rognes 1986), but are found in at least some species of all other sub- groups of the Calliphoridae here recognized. No spe- cies of Sarcophagidae are yet known to possess alpha setae. The few botflies examined by me for this char- acter (Cuterebra atrox Clark, Gasterophilus intestinalis (De Geer), Hypoderma tarandi (Linnaeus), Oestrus ovis Linnaeus) had no alpha setae, but what appears to be typical alpha setae is shown for Dermatobia homi- nis (Cuterebrinae) and Cobboldia chrysidiformis Rodhain & Bequaert by Patton (1935b, 1937). Character 24. — Female abdominal sternite 8; median division 0 - entire, 1 - divided. Depending on the degree of sclerotization of the median part of the female abdominal sternite 8, this may appear complete (0) or divided (1). The charac- ter was extensively discussed by Herting (1957) and needs only few additional comments. I have scored all taxa of the Tachinidae family-group for the entire (or undivided) condition although a few exceptions oc- cur. In the Hypodermatinae, Hypoderma Latreille provides examples of a completely divided female sternite 8 (Wood 1987a: fig. 14). This may, however, be shown to be a derived condition by reference to the undivided condition found in the genera Oestromyia and Portschinskia Semenov, which are considered as basal lineages of the subfamily (Grunin 1965). Calliphora stelviana (Brauer & Bergenstamm) of the Calliphorinae is another example (Rognes 1991: fig. 182), but here considered derived within its subfamily. Character 25. — Spermathecal ducts; configuration relative to uterus 0 - two ducts fused just before entering the Auteur: Verkorte titel van het artikel uterus, 1 - all ducts enter the uterus sepa- rately. Within the Schizophora and possibly within all of the Cyclorrhapha, it seems to be a groundplan condi- tion that two of the three spermathecal ducts join each other shortly before ending in the uterus, thus leaving the latter with only two openings leading to the spermathecal ducts (Griffiths 1982, Wiegmann 1989). Note that McAlpine (1989: 1429) considered the groundplan of the Calyptratae to have all three spermathecal ducts reaching the uterus separately, relying on Sturtevant (1925-26). The latter author, however, never made extensive dissections of calyp- trate taxa. Griffiths (1982), referring to unpublished data from B. A. Holloway, delimits a clade of the Tachinidae family-group consisting of the Sarcophagidae, Tachinidae and Oestridae based on the complete separation of all three spermathecal ducts at junction with the uterus. My own dissec- tions, however, have revealed another pattern (table 1). I have found the ‘fused’ condition with only 2 openings in the Muscidae (other non-tachinoid cal- yptrate families not examined by me), in the Cuterebrinae and Hypodermatinae, which are the only botfly subfamilies examined (figs. 4, 5), and in all calliphorid subfamilies except Helicoboscinae, Bengaliinae and Phumosiinae (table 1). All Rhinophoridae and Tachinidae examined possess three separate openings. It should be noted that fig- ures of female reproductive organs drawn for other purposes may be unreliable with respect to this char- acter, e.g. that of Mesembrinella peregrina illustrated by Guimaraes (1977: figs. 39, 40). It is shown to pos- sess the ‘all-separate’ condition. In the Sarcophaginae only Sarcodexia lambens (Wiedemann) is known to have two openings, but this is apparently an autapo- morphic condition with the common spermathecal duct very long (Lopes 1941: figs. 8, 10). Among the species of Miltogrammatinae and Paramacro- nychiinae dissected by me, none possess the ‘fused’ condition with two spermathecal ducts joining close to the uterus (table 1). All possess three separate openings, but the openings may be so close to each other that they superficially appear as one. In Sarcotachina subcylindrica Portschinsky and Sarcophila latifrons (Fallen) (figs. 6, 7), both of the Paramacronychiinae, and in Metopia argyrocephala (Meigen) of the Miltogrammatinae, the three sper- mathecal ducts open into a more or less tube-like or stalk-like pouch of the uterus. More dissections of species close to the basal splits within the Miltogrammatinae and the Paramacronychiinae are needed to settle the groundplan condition for these two subfamilies — and thereby probably for all of the Sarcophagidae. This is important as it could be DD TIJDSCHRIET VOOR ENTOMOLOGIE, VOLUME 135, 1992 Table 1. Species dissected for examination of configuration of spermathecal ducts relative to uterus (character 25). 1:1:1 indicates that all spermathecal ducts enter the uterus or a common uterine pouch separately. 1:2 indicates that two spermathecal ducts are fused just before entering the uterus or a common uterine pouch.

The configuration of the spermathecal ducts is interesting as the recent exclusion of some presumed Calliphoridae from the Rhinophoridae may be fur- ther corroborated. An examination of Morinia mela- noptera (Fallen), for example, reveals the fused condi- tion, and according to Downes (1986: fig. 26), this condition is found in Melanomya as well. Both these genera have been treated as Rhinophoridae by Herting (1961), Crosskey (1977), and Tschorsnig (1985a), while they were put in the Calliphoridae by Downes (1965, 1986), Rognes (1986, 1991) and Pape (1986a, 1988). The separate spermathecal ducts of the Sarcophagidae, Rhinophoridae and Tachinidae may have triggered the evolution of a tripartite acro- phallus several times. A tripartite acrophallus is thus a groundplan feature of the subfamily Sarcophaginae (Pape, unpubl.), and tripartition was recently discov- ered in a single species of Miltogrammatinae (Pape 1989). Tripartition has probably evolved once in the Rhinophoridae (Tschorsnig 1985a, Pape 1986a) and several times in the Tachinidae (Andersen 1988). On the other hand, tripartition apparently never evolved in the Calliphoridae, Oestridae nor any of the non- tachinoid calyptrate families. However, many genera of the Bengaliinae show a complicated acrophallus with flaps and membranes that may guide sperm and/or accessory gland material into the openings of the spermathecal ducts and thus effectively be a tri- partition. The lateral acrophallic ducts guiding the accessory gland material from the phallotreme to the female lateral sacs in species of Lucilia Robineau- Desvoidy are obviously not homologous to any of the examples of acrophallic tripartition discussed above as they are invaginations of the external wall of the phal- lic tube (Merritt 1989, Rognes 1991). It should be kept in mind that separate spermathecal openings most probably is a groundplan feature of all of Dip- tera (McAlpine 1981), while this groundplan prob- ably had but a single male gonopore (Wood 1990). Character 26. — Spermathecae; size 0 - equal sized, 1 - one reduced. In the Oestridae, all Hypodermatinae and Oestrinae have one of the three spermathecae reduced (see figures in Grunin 1965, 1966). The Gasterophilini have also been scored as ‘one reduced’ (1) as the total absence of one spermatheca in Gasterophilus obviously has to be considered a reduc- tion. I have no information on size or number of sper- mathecae in the genus Gyrostigma. In the genus Cobboldia, spermathecae of C. chrysidiformis and C. elephantis are figured in Patton (1937), showing three oval or slightly elongated spermathecae of which one is clearly reduced in the former species, slightly re- duced in the latter. All Cuterebrinae may have spher- ical, equal-sized spermathecae, although I have exam- ined only Dermatobia hominis (fig. 4) and Cuterebra atrox, but see also the figure of C. fontinella Clark in Patton (1935b, fig. 6). The Mesembrinellinae and Phumosiinae have elongated spermathecae, which may vary somewhat in size, but both taxa have been scored for equal sized spermathecae (0). I have scored the Tachininae as having spermathe- cae of equal size, thereby considering the few instan- ces of loss of one spermatheca, e.g. in Siphona (Andersen 1983), as secondary. Character 27. — Male sternite 5; configuration of posterior margin 0 - deeply emarginated, 1 - simple or with a shallow emargination. Although the posterior outline of the male sternite 5 shows much variation, the shallow posterior emar- gination in all Oestridae and in the subfamily Paramacronychiinae of the Sarcophagidae is very dis- tinct. In the Miltogrammatinae Chrysogramma and Eumacronychia show a typical deep emargination, while the remaining members of the subfamily have no or a shallow emargination. The groundplan for the Miltogrammatinae has been scored as unknown. Character 28. — Male tergite 6; connection to syntergosternite 7+8 0 - free, 1 - fused. The fused condition is found in all of Paramacronychiinae and apparently in all Oestridae. The fused condition occurs scattered elsewhere in the Tachinidae family-group but cannot be ascribed to the groundplan of any other terminal taxon consid- ered here. Character 29. — Male bacilliform sclerites; configuration 0 - well developed and parallel, 1 - reduced and more or less perpendicular to the me- dian plane. All Sarcophagidae possess reduced bacilliform sclerites (processus longi, divided sternite 10). Usually only very short sclerites remain, and if dis- tinct these are always more or less perpendicular to the median plane. The groundplan of all non-sarco- phagid terminal taxa scored here is characterized by distinctly developed bacilliform sclerites, which are parallel and directed posteriorly. Character 30. — Gonostylus; presence/absence of basal apodeme 0 - apodeme not present, 1 - apodeme present. Pape: Phylogeny of the Tachinidae family-group It has been known for decades, that some or most tachinoid calyptrates possess a small sclerite at the base of the gonostylus (paramere of McAlpine (1981)). This sclerite is figured but unnamed in Rohdendorf (1937), named ‘Gelenkfortsatz’ by Salzer (1968), ‘additional forceps’ by Lopes (1975), and ‘ba- sal parameral apodeme’ by Pape (1990). The impor- tance, in a phylogenetic context, of the presence/ab- sence of this sclerite, was first recognized by Tschorsnig (1985a, b). The latter author found this structure in all Tachinidae, Sarcophagidae, Rhinophoridae, and Calliphoridae examined, but not in the few members of the Gasterophilinae, Oestrinae and non-tachinoid Calyptratae examined. Accordingly, he favoured the hypothesis of Hennig (1976) that the Oestridae are the sister group of all other members of the Tachinidae family-group (Tschorsnig 1985a: 10). Rognes (1991) found no go- nostylar apodeme in Cephenemyia trompe (Modeer) (Oestrinae) and Hypoderma tarandi (Hypodermatinae). I have examined males of Cobboldia chrysidiformis, several Gasterophilus, Hypoderma bovis (Linnaeus) and Oestrus ovis Linnaeus, which all had no apodeme. However, males of Cuterebra neomexicana Sabrosky, Oestromyia leporina (Pallas) and Cephenemyia trompe examined by me show an unambiguous, although small and eas- ily overlooked apodeme at the base of the gonostylus (fig. 1). In a single specimen of Ruttenia loxodontis ex- amined, it appears as if the gonostylar apodeme is partly fused to the gonostylus. Therefore, the ground- plan of the Cuterebrinae is scored as present (1), that of Gasterophilini and Cobboldiini as absent (0), and that of Hypodermatinae and Oestrinae as unknown (both states occur). A more careful search for this eas- ily overlooked apodeme in the Oestridae is needed. The sclerite may be homologous to the gonostylar apodeme found in other Diptera, part of the gonosty- lus proper, or a unique sclerite arisen de novo in the Tachinidae family-group. Contrary to the internal gonostylar apodeme found in other Diptera it forms part of the external cuticle, and the first possibility seems uncorroborated or even falsified. As nothing seems to indicate that the apodeme should have split from the base of the gonostylus, I am in favour ofa de novo origin, but note that the use of the presence/ab- sence of this apodeme in a phylogenetic context does not require an explicit interpretation of its potential homology with structures found in groups not in- cluded in the analysis. Character 31. — Phallus; ventral surface of distal section 0 - smooth, 1 - with sclerotized denticles. The denticles (Körnchen oder Dörnchen’ of Tschorsnig (1985b: 61)) are found throughout the 57 TIJDSCHRIFT VOOR ENTOMOLOGIE, VOLUME 135, 1992 Tachinidae family-group, and they usually cover a large part of the ventral surface. They are absent from the acrophallus and part of the ventral surface in the calliphorid subfamilies Melanomyinae and Polleniinae (Rognes 1991). In the Sarcophagidae they are absent in several members of the sarcophagid subfamily Paramacronychiinae, e.g. Goniophyto Townsend, Wohlfahrtia Brauer & Bergenstamm and Sarcophila Rondani. They are restricted to the lateral styli in many Sarcophaginae. In the Tachinidae, Tschorsnig (1985b) recorded an absence of phallic denticles in part of the subfamily Phasiinae. All taxa of both the Sarcophagidae and the Tachinidae, how- ever, have been scored as denticled (1) because no ev- idence is present that favour a basal position of the ‘non-denticled’ taxa. In the Gasterophilinae, denticles are present in Cobboldia (Patton 1937), absent in Gasterophilus. | have not examined Gyrostigma for this character. Similar phallic denticles are absent from the Muscidae (personal observations, few samples), and in non-tachinoid Calyptratae they are known on- ly from a subgroup of Delia Robineau-Desvoidy (Anthomyiidae), where the condition most probably has developed independently (Griffiths 1982). Character 32. — Dorsolateral phallic processes; apical configuration 0 - confluent with distiphallic wall throug- hout, 1 - separate from wall of distiphallus, Le. with a free tip. Rognes (1986, 1991) stressed the phylogenetic im- portance of the free-tipped condition and considered this as synapomorphic for Calliphoridae and Rhinophoridae. Subfamilies of the Sarcophagidae and Tachinidae have been scored as inapplicable for this character as their dorsolateral processes are fused along the dorso- median line. Some Sarcophaginae possess what ap- pears to be free dorsolateral processes, most notably Sarcodexia lambens (fig. 2) but also some species of Blaesoxipha Loew subgenus Acridiophaga Townsend. These processes, however, although derived from the dorsal plate, are probably not homologous to the pro- cesses seen in the Calliphoridae. A very large clade in Pape: Phylogeny of the Tachinidae family-group the Sarcophaginae, containing both Sarcodexia Townsend and Blaesoxipha, is defined by the presence of a transverse, desclerotized strip distally on the dor- sal side of the phallus, separating what is generally called a juxta from the more proximal part of the dor- sal plate. The juxta may well contain elements of the fused dorsolateral processes, which means that any free sclerotized prongs in juxtate Sarcophaginae can- not be considered homologous to the free tips of the dorsolateral processes in Calliphoridae and Rhinophoridae. All calliphorid subfamilies have been scored for free tips except the Bengaliinae and the Rhiniinae. For the Bengaliinae, my knowledge of phallic structures is rather limited, and the groundplan of dorsolateral processes has been scored as unknown/inapplicable. As dorsolateral processes in the Rhiniinae seem to have fused in the dorsomedian line, the character has been scored as unknown/inapplicable as in the Sarcophagidae and Tachinidae (see discussion under character 34 below). All Hypodermatinae possess sclerotized processes laterally or dorsolaterally on the phallus and with tips just free of the wall (see figures in Grunin 1965). No other member of the Oestridae possesses similar pro- cesses. These processes are strikingly similar to the dorsolateral phallic processes of the Calliphoridae, and apical microserration may suggest a similar func- tion. They differ, however, by apparently originating from the lateral plates rather than from the dorsal plate. Rudiments of the dorsolateral processes may be seen at the base of the dorsal plate (Grunin 1965: fig. 123). This puts serious doubt on the homology to the dorsolateral processes seen elsewhere in the Tachinidae family-group and I have scored the Hypodermatinae for the confluent condition. Both Rognes (1986) and Pape (1986a) found no examples of free dorsolateral processes in the Tachinidae, and checking the numerous illustrations, eg. in Wood (1972), Shima (1986, 1988), Tschorsnig (1985b) and Cantrell (1988), does not re- veal any. It should be noted, however, that Malayia and some undescribed Bezzimyia (Pape unpubl.) pos- sess free tips of dorsolateral processes, but I regard Figs. 1-3. Details of male terminalia. — 1.

The Rhinophoridae have been scored as unknown for the present character as both conditions are of widespread occurrence. Processes free from distiphal- lic wall are found in Mimodexia, Malayia, Phyto and some Bezzimyia; processes confluent with distiphallic wall are present in remaining genera (see figures in Tschorsnig (1985a) and Pape (1986a)). The present knowledge of generic phylogeny is largely that of Tschorsnig (1985a) and Pape (1986a), with addition- al comments in Pape (1987d), but both authors did not consider Bezzimyia and Malayia. A proper evalu- ation of the most probable groundplan state is there- fore not possible at present. As I have never encountered distinctly free tips of dorsolateral processes within Muscidae and Anthomyiidae, these have been scored as confluent (0). This is in agreement with Hennig (1976: 690), who pointed out the free tips of the calliphorid dorso- lateral processes and mentioned that dorsolateral pro- cesses in the Anthomyiidae were confluent with the distiphallic wall (‘Bei den Anthomyiidae scheinen [die dorsolaterale Fortsätze] nur die Seitenteile einer geschlossenen in der Mitte membranösen oder eben- falls sklerotisierten Dorsalwand zu bilden’). Character 33. — Acrophallus; position 0 - strictly terminal, 1 - on ventral surface of phallus. All terminal taxa except the sarcophagid subfami- lies Paramacronychiinae and Sarcophaginae possess a groundplan phallus with the spermexit almost per- fectly terminal and situated on the longitudinal axis of the phallus, although this may be curved in the me- dian plane. A very characteristic modification of both the paramacronychiine and sarcophagine phallus is the position of a very well-defined acrophallus ven- trally on the distal part of the phallus. Character 34. - Dorsolateral phallic processes; dorsomedian configuration 0 - separate, 1 - fused. Phallic dorsolateral processes are here considered homologous throughout the Tachinidae family- group with the exception of the juxtate Sarcophaginae discussed under character 32 above. Tschorsnig (1985b: 119) suggested that the dorsolat- eral processes of the Calliphoridae and Rhino- phoridae were homologous to the dorsal extension found in the Tachinidae, which I fully accept. To my knowledge, separate dorsolateral processes are un- known in the Tachinidae (if the exclusion of Malayia and Bezzimyia is accepted), and the tachinid taxa have been scored as fused (1), although some species may lack dorsolateral processes altogether. In the Sarcophagidae, all species possess fused dorsolateral 60 processes (see for example Pape 1986c: figs. 1-4, Pape 1987a: figs. 29-33). Although some members of the subfamily Miltogrammatinae may have the dorsal plate partly desclerotized medially, they never present fully separate dorsolateral processes. The Hypo- dermatinae have been scored as unknown for this character as I consider the dorsolateral plates to be re- duced. I have not been able to fully evaluate the phallic groundplan of the Anthomyiidae and Muscidae, which have been scored as unknown. Character 35. — Uterus; presence of ventral bilobed pouch 0 - not present, 1 - present. A bilobed uterine pouch for embryonating eggs is found in the Sarcophagidae and seems here to be present without exceptions. In the botflies, all Oestrinae have a bilobed sac or pouch extending from the uterus, and although somewhat different in shape and tracheation, the Oestrinae have been scored like the Sarcophagidae (1). In the Tachininae (as here de- fined) eggs are retained (incubated or embryonated) in the uterus, which often becomes greatly distended, but no pouch is formed. Eurychaeta palpalis (Robineau-Desvoidy) of the Helicoboscinae has a pouch-like extension of the uterus, but this is never bilobed (Rognes 1986). Large incubatory pouches are known from Bellardia Robineau-Desvoidy and Onesia Robineau-Desvoidy (Calliphorinae), but these are lateral (Rognes 1991). Character 36. — Oviposition behaviour; deposition relative to food source 0 - eggs (or larvae) deposited directly on the larval food source, 1 - eggs (or larvae) deposited away from the food source. As correctly stated by Wood (1987b: 1189), the deposition of eggs away from the host in the Rhinophoridae is ‘unusual among calyptrates’. McAlpine's (1989: 1501) claim that this is a plesio- morphic groundplan character state of this family is simply unsupported and may have come from Crosskey's (1977: 6) statement that the Rhino- phoridae possess an ‘oviposition habit of great sim- plicity and apparent primitiveness'. Another instance of oviposition away from the host is found in the genus Pollenia. As the biology of oth- er genera of the Polleniinae is largely unknown, this subfamily has been scored as 1. I know of no other calliphorid subfamily (as here defined), where ovipo- sition away from the food source is a groundplan character state. Within the Sarcophagidae, Sarcophaga Meigen (s.str.) and at least some species of Miltogrammatinae (Phrosinella Robineau-Desvoidy and Eumacronychia) possess state 1 (Eberhardt 1955, Downes 1955, Lopes 1982a). As the groundplan of all other sarcophagid genera, for which extensive bio- logical knowledge exists, seems to be characterised by state 0, the sarcophagid subfamilies have been scored as such. The gluing of eggs to the host-wasp carrying prey to the nest within some Miltogrammatinae (Day & Smith 1980) is here considered derived. Within the Oestridae, all Cuterebra oviposit in places fre- quented by the host, but never directly on a host spec- imen. Dermatobia hominis uses a carrier for its eggs, while the habit of oviposition for Neocuterebra and Ruttenia is unknown. Almost all non-cuterebrine bot- flies ovi- or larviposit directly on their host. One ex- ception is Gasterophilus inermis (Brauer), which de- posits eggs on grassblades and the like. This is here considered a derived condition. Within the Hypodermatinae, species of Portschinskia seem to produce eggs without any attachment apparatus (Grunin 1965), but no observation has been made of the oviposition, nor have any naturally deposited eggs been found. Grunin (1965) suggested an oviposition behaviour similar to that of Cuterebra, and I have scored the groundplan of the Hypodermatinae as un- known for this character. Character 37. — Egg, ventral surface 0 - not glued to substrate, 1 - glued to substrate. Many members of the Calyptratae will deposit eggs that are sticky and therefore adhere to the surface on- to which they are positioned. This, however, is easily distinguished from the condition of all oviparous members of the Oestridae and Tachinidae, where eggs are glued firmly to the substrate. The Sarcophagidae are mainly ovi-larviparous but some will deposit embryonated eggs ready to hatch, espe- cially when an ample larval food source induces pro- lific larviposition. In the subfamily Miltogram- matinae, some species may glue eggs to the host wasp (Day & Smith 1980), while others deposit eggs freely (Maneval 1929), and the groundplan of this subfam- ily has been scored as unknown with regard to this character. Nothing is known on egg structure and deposition in Neocuterebra and Ruttenia. Character 38. — Egg; hatching mechanism 0 - by peeling off a long flap, 1 - by discar- ding an anterodorsal cap. In the Tachinidae, eggs of the non-embryonating groups Phasiinae and the Exorista genus-group pos- sess anterior cleavage lines flanking the aeropyles and delineating a somewhat operculum- or caplike struc- ture through which the larva emerges (Herting 1960, Wood 1987c: fig. 110.264). This is very similar to the condition in plastronate groups, although with shorter hatching sutures. I have scored both groups as Pare: Phylogeny of the Tachinidae family-group 0. Many different hatching mechanisms are known from the Tachininae, and they have been scored as unknown with regard to the groundplan for this char- acter. Very little is known about egg structure and function in the Sarcophagidae (scored as inappli- cable/unknown), but eggs of at least one species of Miltogrammatinae hatch through pushing off an an- terior egg cap or operculum (Day & Smith 1980). In the genus Sarcophaga (s.l.), no preformed lines or weaknesses seem to exist, and the larva emerges by bursting the chorion (Baudet 1980). Eggs of all ovip- arous Oestridae hatch by discarding an anterodorsal cap (Wood 1987a: fig. 15, 17). Within the Calliphoridae, Booponus of the Bengaliinae is to my knowledge the only known tax- on with a somewhat oestrid-like hatching mecha- nism. Character 39. — Progeny at deposition; stage of development 0 - unembryonated eggs, 1 - embryonated eggs or prehatched first instar larvae (ovo- larviparous), 2 - larvae that for an extended period have received nourishment within the uterus (true larviparous). In the Sarcophagidae, eggs do not necessarily hatch immediately upon deposition. They are always em- bryonated and except for Sarcophaga nigriventris Meigen, which is stated to deposit second instar lar- vae (Séguy 1965), I know of no cases of sarcophagid larvae being nourished in utero. In a species of Oebalia Robineau-Desvoidy, which oviposits directly on the ‘host’ carrying the prey, the first instar larva within the egg is fully mature and postpones hatching simply to await being transported to the host nest by its carrier (Day & Smith 1980). No embryonation takes place in the Rhinophoridae, and in the Oestridae only in the larviparous subfamily Oestrinae. All Phasiinae are stated by Wood (1987c) to deposit unembryonated eggs, and the Tachininae are here defined as including all embryonating Tachinidae. Within the Calliphoridae the macro- or unilarvip- arous habit of the Helicoboscinae, Ameniinae, Phumosiinae and Mesembrinellinae is well known, but only the Mesembrinellinae will nourish the larvae during intra-uterine life (Rognes 1986, Crosskey 1965, Guimaraes 1977, Ferrar 1978). Character 40. — Mandible of first instar larva; relative development 0 - present as a distinctly sclerotized plate, 1 - reduced to an ill-defined sclerotization on side of mouth opening. In all Tachinidae, what is probably a reduced man- dible is present as ‘a vaguely defined sclerotized area 61 TIJDSCHRIFT VOOR ENTOMOLOGIE, VOLUME 135, 1992 on side of mouth opening, without hook-like extension’ (Wood 1987c: 1196). None of the non-ta- chinid terminal taxa applied here has a similar man- dibular reduction as a groundplan feature. Note that McAlpine's (1989) statement that calliphorid first in- star larvae lack paired mandibles is erroneous and was taken uncritically from Hennig (1973). All Calliphoridae possess easily recognizable paired man- dibles in the first instar larva, although sometimes quite small (Rognes 1991). Character 41. — Labrum of first instar larva; connection to remaining cephalopharyngeal skeleton 0 - labrum more or less connected to, but always distinct from remaining cephalop- haryngeal skeleton, 1 - labrum firmly fused to, and contiguous with remaining cephal- opharyngeal skeleton. The unique cephalopharyngeal skeleton of the first instar tachinid larva is discussed and described suffi- ciently in the literature (e.g. Ferrar 1987). With no exceptions within the Tachinidae, and no homopla- sies in the possible groundplan of any of the other ter- minal taxa, this character needs no further explana- tion. Character 42. — Segments of first instar larva; development of spines 0 - without bands of strong spines, 1 - with bands of strong spines. First instar larvae of all Oestridae are well-known for their bands of usually strong spines (Grunin 1965, 1966, 1969; Wood 1987a). These spines are always present in the first instar but may be modified or re- duced in later instars. Character 43. — Spiracular plates of third instar larva; development of peritreme and ecdysial scar 0 - complete, 1 - incomplete. All larvae of Sarcophagidae have the peritreme in- complete ventro-medially and the ecdysial scar from the second instar posterior spiracles is absent or indis- tinct. A similar configuration belongs to the ground- plan of the calliphorid subfamily Chrysomyinae (Rognes 1991). In the Cuterebrinae both Dermatobia and Neocuterebra show an incomplete peritreme while that of Cuterebra is complete. The cuterebrine groundplan has been scored as unknown for this character. Character 44. — Posterior spiracles of second and third instar larva; position relative to surface 0 - more or less level with surrounding sur- face, 1 - set in a recession or cavity. In the Sarcophagidae, close to all species for which larval morphology is known have the posterior spira- 62 cles concealed in a distinct recession. The only excep- tions known to me are species of Amobia Robineau- Desvoidy sensu stricto (Miltogrammatinae), Macronychia, and at least some Tricharaea (Sarcophaginae), but these are here considered homo- plasies. Somewhat similar conditions in the Gasterophilinae, where upper and lower lips can be pulled together, enclosing the spiracles, and in the Cuterebrinae, where the posterior spiracles can be pulled into the preceding segment, are considered non-homologous. Character 45. — Parastomal bars of third instar larva; presence/absence 0 - parastomal bars present, 1 - parastomal bars absent. Parastomal bars are easily recognized when present and need no further comments (see figures in Ferrar (1987)). Character 46. — Posterior spiracle of second and third instar larva; vertical position of ecdysial scar 0 - low (or ventrally) on the spiracular plate, 1 - near the horizontal diameter of the spiracular plate. This character has not previously been discussed in the literature, but illustrations of spiracular plates, e.g. in Ferrar (1987), show the difference in position of the ‘low’ ecdysial scar of non-botfly calyptrates com- pared to the much higher ecdysial scar of the botflies. Character 47. — Posterior spiracles of second and third instar larva; configuration of openings 0 - three slits, 1 - a porous plate. The porous condition is found in the Hypo- dermatinae and Oestrinae of the Oestridae (Zumpt 1965, Howard 1980, Ferrar 1987). Cuterebra de- serves mention as the configuration with highly tor- tuous slits could be taken as resembling that found in Oestrinae and Hypodermatinae (see, e.g., Baird & Graham (1973: fig. 7D). However, the spiracular openings are still conspicuous slits, not porous plates, and with a clearly discernible tripartition. Typical tri- partite slits occur in Dermatobia, Ruttenia and Neocuterebra (Ferrar 1987). Character 48. — Posterior spiracular plates of second and third instar larva; configuration 0 - two isolated plates, 1 - plates fused in the median line. Second and third instar larvae of all members of both Cobboldia and Gasterophilus + Gyrostigma have the spiracular plates fused (Zumpt 1965). Ferrar (1987: 137) mentioned that in Dermatobia hominis ‘the two plates [of the posterior spiracles] are appar- ently joined, and have a single median button between the slits’. Figures in Kremer et al. (1978), however, show neither peritreme nor button. The fused character state has not been found in any other taxon of the Tachinidae family-group. Character 49. — Puparium; hatching mechanism 0 - anterior end splits into a dorsal and a ventral piece, 1 - anterior end splits off on- ly one, dorsal piece. The groundplan condition of puparial hatching in the Cyclorrhapha (Ferrar 1987), seems to be a split- ting off of an anterior cap, and this typically has a lat- eral suture causing further splitting into a ventral and a dorsal half. In the botflies, the ventral half is more or less fused to the remainder of the puparium and the dorsal half is flattened to a lid-like structure. UNSCORED CHARACTERS OF POTENTIAL PHYLOGENETIC VALUE As mentioned previously, character matrices are never complete, and some characters have not been included in the analysis because of uncertainty with regard to proper scoring. These are dealt with below in the hope that future studies will allow inclusion in the matrix. Character a. — Eyes; holoptic/dichoptic condition The typical holoptic condition with frontal vitta completely obliterated between eyes is widespread and common in the male sex of Calliphoridae, Muscidae and Anthomyiidae (Huckett 1987: fig. 4, Huckett & Vockeroth 1987: fig. 5, Shewell 1987a: fig. 6). The holoptic condition occurs scattered in the Tachinidae and is present in a few Rhinophoridae (some Phyto and Stevenia Robineau-Desvoidy), Sar- cophagidae (Agria Robineau-Desvoidy, Blaesoxiphella Villeneuve) and Oestridae (some Cuterebra, Pharyngobolus Brauer). Much variation exists between and even within genera and groundplan estimates are difficult to assess at the subfamily and family levels. Character b. — Intrapostocular setulae; presence/absence Presence of intrapostocular setulae have been used in the definition of the Calliphoridae in spite of sever- al exceptions: absences within the Calliphoridae as well as occurrences outside this family (Rognes 1986). I have not made a sufficiently extensive search for intrapostocular setulae to give a reliable scoring. They appear to be widespread in the non-rhiniine and non-ameniine Calliphoridae, including rare oc- currences in the possibly basal lineage Helicoboscinae. I have not found any intrapostocular setulae in the Oestridae, Sarcophagidae and Rhinophoridae. Rognes (1986:86) found such setulae Pape: Phylogeny of the Tachinidae family-group in Dexiosoma caninum (Fabricius) and Tachina fera Linnaeus of the Tachinidae. An extensive search in the Muscidae and Anthomyiidae is needed. Character c. — Antennal arista; setosity Whether the arista is bare or plumose or some in- termediate condition is often used for diagnostic pur- poses at various levels within the Tachinidae family- group. The character is, however, quite variable, and I have failed in breaking it up into only a few clearcut states. The setose condition covers a whole array of types, from the single row of dorsal and ventral rays in Musca (Muscidae) to the bottle-rinser-type of Melanophora roralis (Rhinophoridae). However, the type with rays arranged dorsally as well as ventrally, with at least the dorsal row being double in the proxi- mal part, and no hairs or pubescence on the sides is very characteristic. This ‘calliphorid type’ arista is found widespread in all non-helicoboscine Calliphoridae. Eurychaeta Brauer & Bergenstamm, which is the sole genus of the Helicoboscinae, has a unique arista with medium long rays on the whole surface, although with the dorsal and ventral rays lon- gest. Members of the Rhiniinae have either a bare or a pectinate arista, with the latter type being identical to the typical calliphorid type except for the lack of ventral rays. In the Oestridae, Dermatobia and most Cuterebra of the Cuterebrinae possess a plumose or pectinate calliphorid type arista. All other botflies have a com- pletely bare arista. No members of the Rhinophoridae and Tachinidae possess a calliphorid type arista as here de- fined. When a similar arista occurs in the Sarcophagidae, like in Agria and Sarcophila of the Paramacronychiinae, the arista often has distinct pu- bescence on the sides. In the Sarcophaginae, a plu- mose arista may be a groundplan feature and at least Ravinia Robineau-Desvoidy and Oxysarcodexia Townsend have a calliphorid type arista. In the large Sarcophaga sensu lato, however, the arista has pubes- cence on the sides. The apparently bare arista of the Miltogrammatinae and several Tachinidae is covered with short or minute pubescence. The Rhinophoridae present several examples of a plumose arista, but never of the calliphorid type de- scribed above. McAlpine's (1989: 1501) statement that a plumose arista in the Rhinophoridae is an im- portant plesiomorphic groundplan character state is to some extent contradicted by himself as he simulta- neously, although tentatively, used this state as autap- omorphic for the Calliphoridae. My knowledge of the Muscidae and Anthomyiidae is too sparse to give a thorough discussion on varia- tion in aristal setosity. More accurate descriptions of different configura- 63 TIJDSCHRIFT VOOR ENTOMOLOGIE, VOLUME 135, 1992 tions of aristal setosity, preferrably using SEM, and further knowledge of their taxonomic distribution in all of the Calyptratae are needed before this character can effectively be used in interfamilial phylogenetic analyses. Character d. — Outer posthumeral thoracic seta; position relative to the prealar seta The position of the outer posthumeral seta outside (i.e. lateral to) a sagittal line through the prealar seta has often been used in the definition of the Calliphoridae (Rognes 1986). This lateral position seems to characterize the groundplan of all subfami- lies except perhaps the Ameniinae, where both con- ditions occur (Crosskey 1965), and the Polleniinae, where the outer posthumeral seta is in line with the prealar seta in Pollenia, absent in Morinia (Rognes 1991). The groundplan of both the Tachinidae and Sarcophagidae has the outer posthumeral in a median position relative to a sagittal line through the prealar seta. Scoring the Rhinophoridae presents some pro- blems. The outer posthumeral seta is generally absent, but when present as a fine seta in some species of Phyto, especially distinct in Phyto sordidisquama Villeneuve, it is in the lateral position. A scoring as absent would be equal to inapplicable and therefore rather uninformative; a scoring as lateral would igno- re all the absences. The character is inapplicable for the Oestridae, as no bristly thoracic setae are differen- tiated. I have not been able to give a reliable estimate of the groundplan for this character in the Antho- myiidae and Muscidae. Character e. — Ventral surface of costa between junction with subcosta and R;; setosity This character is diagnostically valuable for various groups in the Calyptratae and clearly deserves more attention (Rognes 1991: fig. 8, inset). Within both the Calliphoridae and the Oestridae, this part of costa is setose in the majority of species, while the bare con- dition seems to be common and widespread in the Tachinidae and Sarcophagidae. In the latter family only a few genera of Sarcophaginae, e.g. Boettcheria Parker, Emdenimyia Lopes and Notochaeta Aldrich, possess the setose condition. Both conditions occur in the Rhinophoridae, Muscidae and Anthomyiidae with no obvious choice for the most probable groundplan condition. Character f. — Anterior malpighian tubules of adults; length This character state has not previously explicitly been used as a tachinid groundplan feature, and it is admittedly based on sparse evidence. Hori (1962) depicts the alimentary canal of Sturmia sericariae 64 (Rondani), Prosena siberita (Fabricius) and Tri- gonospila transvittatum (Pandellé), which all possess reduced anterior malpighian tubules, which here are defined as the pair of tubules arising from a common malpighian duct in the right side of the gut and run- ning anteriorly along the midgut. Three other tachin- ids are listed in Hori's (1962) table 1 and are likewise stated to have shortened anterior tubules. As in all ot- her Calyptratae figured by Hori, the anterior tubules of the Tachinidae run forwards along the midgut. They do not, however, form a complete loop, with the tubules running all the way back and terminating at about the level of the rectal papillae. Instead, the anterior tubules make a slight curve or a very short loop, before ending well in advance of their starting point. It should be noted that no rhinophorids were dissected by Hori (1962), but specimens of Phyto me- lanocephala (Meigen) dissected by me show the long configuration of anterior malpighian tubules. Character g. — Female terminalia; length Long, retractile telescopic female terminalia are common and widespread in both the Anthomyiidae and Muscidae. In the Rhinophoridae, long telescopic terminalia occur in all genera except Paykullia Robineau-Desvoidy and Melanophora Meigen. In the Calliphoridae, all genera which have retained a plesio- morphic oviposition habit have telescopic female ter- minalia. In the Tachinidae, with the present ex- clusion of Malayia and Bezzimyia, all species possess shortened female terminalia, if not secondary length- ened, e.g. in some members of the phasiine tribe Cylindromyini. In all of Sarcophagidae, female termi- nalia are much shortened, and this holds for Chilopodomyia Lopes & Tibana as well, even though this genus was stated to have a telescopic ovipositor (Lopes & Tibana 1984). The subfamilies of Oestridae may also possess shortened female termina- lia as a groundplan character state. Long female ter- minalia are unknown in the Cuterebrinae and Oestrinae, and the elongate terminalia of most fema- le Gasterophilus are neither retractile nor telescopic. In the Hypodermatinae females of Hypodermatini and Oestromyini have long and telescopic ovipositors, but female terminalia of the genus Portschinskia are short. I have not been able to break the structural diver- sity of female terminalia into unambiguous states ex- cept as a simple, and therefore probably little phylo- genetically informative division into a short versus a telescopic condition. Also, the character is closely tied to the mode of oviposition, and it may be directly misleading to score larviparous groups and groups with a derived oviposition behaviour. Character h. — Female tergites 7 and 8; median division McAlpine (1989) considered the division of fema- le abdominal tergites 7 and 8 as synapomorphic for the Calliphoridae. I know of no Calliphoridae having these tergites undivided, while the undivided con- dition occurs in at least some species of all other fa- milies of the Calyptratae (Herting 1957). However, most non-calliphorid terminal taxa included in the present analyses show examples of both the divided and the undivided condition and would be scored as unknown. Information is needed from genera consi- dered to be close to the basal splits within each taxon. Character i. — Spermathecal ducts; enclosion/non- enclosion in acommon sheath Hori (1961) distinguished between what he called a 1:2 and a 1:1:1 configuration, where either two spermathecal ducts were enclosed in a common she- ath or all three were perfectly free of each other. This should not be confused with character 25, which deals exclusively with how the three ducts join the uterus. Enclosion in a common sheath, therefore, does not mean that they share a common duct or a common opening into the uterus. Apparently, all species of Sarcophagidae and Tachinidae examined by Hori possess perfectly free spermathecal ducts, while all Calliphoridae and al- most all non-tachinoid calyptrates with 3 spermathe- cal ducts examined showed the paired configuration. Within the Rhinophoridae, freshiy killed female spec- imens of Phyto melanocephala dissected by me showed the paired condition with two spermathecal ducts closely appressed, while a female of Melanophora ror- alishad the two ducts only loosely connected. Among the Sarcophagidae, the miltogrammatine species Senotainia litoralis Allen figured by Allen (1926: fig. 25) seems to possess a paired configuration, while the pairing of spermathecal ducts in S. trilineata (Wulp) seems to be very loose (Allen 1926: fig. 20). I have dissected freshly killed specimens of Brachicoma devia (Fallen) of the Paramacronychiinae which showed ei- ther a free condition or a condition with two loosely connected ducts. In the Oestridae, the few figures available do not allow a definite conclusion (Catts 1964; Grunin 1965, 1966), but in the Tachinidae no examples of joined or paired spermathecal ducts are known (S. Andersen, pers. comm.). While dissection of dried females may give easy access to information on how the spermathecal ducts enter the uterus, fresh or properly fixed specimens are required to examine whether or not the ducts are paired or free. I have not been able to score the families consistently on the sparse material examined. Character j. — Female accessory glands; attachment to oviducts The detailed figures of Hori (1961) reveal another Pape: Phylogeny of the Tachinidae family-group character that may prove to contain phylogenetic in- formation, the attachment/non-attachment of female accessory glands to the oviducts through an extension of their sheath of connective tissue. In all Calliphoridae and non-tachinoid Calyptratae figured, the female accessory glands are distinctly attached (see also Kurahashi 1970: fig. 3), while they are free in all Sarcophagidae and Tachinidae. Fresh females of Phyto melanocephala and Melanophora roralis (Rhinophoridae) examined by me both have the ac- cessory glands unattached. A single female of Brachicoma devia (Sarcophagidae: Paramacro- nychiinae) seen had the accessory glands suspended in a thin strand, and the female reproductive system of Gonia sp. (Tachinidae: Tachininae) depicted in Pantel (1910, identified as atra Cockerell and repro- duced in Thompson (1963: fig. 2)) shows accessory glands likewise loosely attached to the oviducts. The only figures available of internal reproductive organs of female botflies suggest that the accessory glands are unattached (Catts 1964: figs. 3-7 (Oestrinae), Grunin 1965: fig. 37 (Hypodermatinae), Grunin 1969: figs. 16-20 (Gasterophilinae)). These figures, however, are hardly reliable as the dissections were not made for the special purpose of examining this fe- ature. Character k. — Uterus; presence/absence of lateral sacs The uterus of many Calliphoridae, e.g. species of the genera Calliphora Robineau-Desvoidy, Lucilia and Pollenia, possesses distinct lateral sacs. These sacs seem to receive the tips of the dorsolateral phallic pro- cesses during copulation (Rognes 1991). Nothing equivalent is known from the Sarcophagidae (Lopes & Kano 1968), which do not possess lateral sacs (Hori 1961), nor from the common house fly (Degrugillier & Leopold 1973), which possesses dis- tinct lateral sacs but no free dorsolateral processes. No lateral sacs have been shown to occur in non-callip- horid tachinoids (I have examined females of Melanophora roralis and Phyto melanocephala of the Rhinophoridae). Character |. — Male terminalia; resting position Wood (1987a: 1148) described the male terminalia of the Oestridae as being ‘strongly retracted, and car- ried rather far forward on underside of abdomen’. This is distinct from the possible groundplan of the Tachinidae family-group, where male terminalia are almost apical. Many subfamilies within the Calliphoridae, with the notable exception of the Helicoboscinae, have the male terminalia slightly dis- placed forwards on the underside of abdomen. I have not, however, been able to produce an exact measure for this character. 65 TIJDSCHRIFT VOOR ENTOMOLOGIE, VOLUME 135, 1992 Character m. — Testes; shape Shape of testes may provide interesting phyloge- netic information. In the Paramacronychiinae and Sarcophagidae, testes are of a uniform shape with a constriction proximal to middle. In the Tachinidae, a pyriform shape of testes may belong to the ground- plan (see numerous figures in Townsend (1942) and Hori (1960)). Exceptions, however, exist and rigo- rous use of this character depends on more infor- mation from all terminal taxa. Character n. — Testes; position relative to fat body Based on data from Hori (1960), ‘testes enveloped in fat body’ was used by McAlpine (1989) to corro- borate the monophyly of the Calliphoridae. However, data from many more calliphorid genera and especially from the Oestridae and Rhino- phoridae, are needed before it will find proper usage. Character o. — Median phallic sclerotization; relative development This structure (= ‘Mesohypophallus’ of Salzer (1968)) was given the poor term ‘spermduct scle- rotization by Pape (1986a) and later renamed ‘me- dian sclerotization’ (Pape (1987d) following Tschorsnigs (1985a, b) ‘Medianleiste des Ventralsklerits’). Although it may appear to be in- ternal, as the ventral part of the phallus often is slight- ly invaginated, it is part of the phallic tube, not the sperm duct, as correctly stated by Tschorsnig (1985a). A median sclerotization is often present and well developed in the Tachinidae (see figures in Tschorsnig (1985b)), less distinct and often shorte- ned in the Oestridae. The groundplan of the Rhinophoridae and Calliphoridae most probably is a well developed median sclerotization running the full length from the ventral plates to the acrophallus. In the Sarcophagidae, the median sclerotization is never complete. What could be a short median scle- rotization occurs sporadically in the Miltogram- matinae (e.g. Pape 1987a: fig. 133), but no trace of a median sclerotization seems to be present in the Paramacronychiinae. Within the Sarcophaginae, the highly modified phallus makes homologies obscure, but a median sclerotization is either absent or may have given rise to the vesica and all or part of the me- dian stylus. Character p. — Dorsolateral phallic processes; serration of tip A point of interest relating to the calliphorid phal- lus is that the dorsolateral processes often are equip- ped with serrations along the free part of their tip. In Lucilia cuprina (Wiedemann), these free, serrated tips have been shown to tear slits in the cuticular lining (intima) of the lateral sacs of the uterus. The curved 66 dorsolateral processes assist in guiding the accessory gland material into intra-cuticular spaces (Merritt 1989). Eurychaeta palpalis (Helicoboscinae) and several species of Calliphorinae, Chrysomyinae, Melanomyinae, Mesembrinellinae and Polleniinae li- kewise possess dorsolateral processes with some kind of serration of the apical part (see figures in Guimaräes (1977), Kurahashi (1970, 1971) and Rognes (1986, 1987, 1988, 1991)). Rognes (1988: 342) considered the presence of ‘small to minute tubercles’ on the tip of the dorsolateral processes as apomorphic within Pollenia and as an underlying sy- napomorphy corroborating a clade consisting of his semicinerea-group and rudis-group. It may be, however, that the synapomorphy should include all of the Calliphoridae. I have not seen any serrations, teeth or tubercles on the apical part of the very callip- horid-like dorsolateral phallic processes of Phyto spp. nor in the undescribed species of Bezzimyia shown in fig. 3, although extensive SEM studies are needed. It is tempting to postulate an ancestral calliphorid type of copulation which, possibly repeatedly, led to an elongation of the free tips of the dorsolateral process- es with or without apical serration. It is interesting in this context that many Calliphoridae with long, free dorsolateral processes have the acrophallus equipped with a pair of lateral ducts on the external wall of the acrophallus. These ducts seem to facilitate the flow of accessory gland secretion from the gonopore to the slits made by the dorsolateral processes (Merritt 1989, Rognes 1991). Character q. — ß-alanyl-L-tyrosine (‘sarcophagine’); presence/absence in larval hemolymph The accumulation of the dipeptide sarcophagine in larval hemolymph of at least Agria housei Shewell (Paramacronychiinae) and several species of Sarco- phaga sensu lato (Sarcophaginae) is interesting as ‘8- alanine and tyrosine have never been detected in peptide linkage in proteins; nor has the free dipeptide been observed in any other natural source’ (Bodnaryk 1970: 349). Later investigations by Bodnaryk (1972), however, have revealed sarcophagine in one species of Tachinidae. The Miltogrammatinae have not yet been examined for this character. Character r. — Larval pharynx; presence/absence of a filter apparatus McAlpine (1989) corroborated the monophyly of his parasitic clade Oestridae + Rhinophoridae + Ta- chinidae by the absence of a larval pharyngeal filter. I have insufficient information on the distribution of this character, e.g. in the Miltogrammatinae and possibly basal calliphorid lineages like the Heli- coboscinae and Bengaliinae, to be able to make a pro- per scoring. Character s. — Labrum of first instar larva; size A labrum is completely absent in the Rhi- nophoridae (Bedding 1973), it is small but still dis- tinct in the Sarcophaginae (Lopes 1982b) and Oestrinae (Grunin 1966). The labrum is short in the Cuterebrinae and Hypodermatinae (Grunin 1965, Ferrar 1987), long and tapering in the Gasterophilini (Grunin 1969). In the Calliphoridae, a labrum is usually well developed, but it is absent in the genera Bellardia and Onesia (Calliphorinae) and in Proto- calliphora Hough (Chrysomyinae) (Rognes 1991). Character t. — Dorsal cornu in cephalopharyngeal skeleton of third (and probably second) instar larva; posterior incision The large majority of species within the Paramacronychiinae and Miltogrammatinae and all of Sarcophaginae have a posterior incision in the dorsal cornu. The few exceptions, however, make groundplan estimates uncertain until generic phylo- geny becomes better resolved. McAlpine (1989) listed an unincised dorsal cornu as a tentative autapomor- phic character state for the Calliphoridae, but he si- multaneously gave this condition as autapomorphic for his clade Oestridae + Rhinophoridae + Tach- inidae. Roback (1951) gave the incised condition as a groundplan feature of the Anthomyiidae. Character u. — Spiracular slits of posterior spiracles in third instar larva; orientation The pattern in the Sarcophagidae is generally that of three more or less vertical slits, and in the Calliphoridae the most widespread condition is three slits radiating in a dorsolateral direction (see figures in Ferrar 1987). In all Gasterophilinae, the three spira- cular slits are parallel and vertical, with secondary convolutions having occurred in Gyrostigma. In Ruttenia the spiracular slits are horizontal or almost so. Character v. — Pupal prothoracic horns; presence/absence Prothoracic horns are present in the pupa of many Calliphoridae and Oestridae and in at least some Tachinidae, while they are seemingly absent in the Rhinophoridae and Sarcophagidae. I have not inclu- ded this character as the number of calliphorid and tachinid subfamilies for which this character is dis- cussed in available literature is strongly limited. Character w. — Puparium; shape The shape of the puparium was used by McAlpine (1989) as a synapomorphy uniting his parasitic clade Oestridae + Rhinophoridae + Tachinidae. These three families were stated to possess a ‘puparium fully Pape: Phylogeny of the Tachinidae family-group inflated with both ends more or less equally hemi- spherical’ (p. 1501). I have been unable to confirm this. Character x. — Egg; surface of area dorsal to micropyle The micropyle is here considered a morphological landmark, which means that the chorion dorsal to this may be considered homologous throughout the Tachinidae family-group. In at least some and proba- bly most Calliphoridae, the surface between the two ridges or pleas demarcating the hatching sutures is modified into a plastron with struts and crossbars. A plastron seems likewise to be present in all Rhinophoridae as well as most Muscidae and Anthomyiidae (Hinton 1960a, b, 1963, 1965, 1967; Bedding 1973; Kitching 1976; Leopold et al. 1978; Richards & Morrison 1972; Erzinçlioglu 1988, 1989; Greenberg & Szyska 1984). The similarity in position and ultrastructure suggest homology. No ta- chinid egg is known to possess a plastron as here defi- ned. Instead, one or more areas with perforations (aeropyles) in the external covering, and therefore with free access to the columnar middle layer, may be found, as shown by figures and SEM-micrographs in Wood (1972). Although the aeropylar areas someti- mes are situated dorsal to the micropyle and between the hatching pleas, I have no a priori evidence that these are homologous to the plastron of the Calliphoridae. The sparse information available on the morpholo- gy of oestrid eggs indicates ‘non-presence’ of a plas- tronic network. It does, however, not allow a more explicit interpretation of homology, e.g. relative to the condition found in the Tachinidae. In Dermatobia hominis (Cuterebrinae), the egg cap is without any trace of a plastronic network and the ex- ternal layer of chorionin, which in this species is sim- ilar to the general egg surface, has no apparent open- ing(s) (Leite 1988). Also in Cuterebra tenebrosa Coquillett is the sculpturing of the egg cap hardly dif- ferent from that of the general surface (Baird & Graham 1973). In Cuterebra cuniculi (Clark) a mod- ified sculpturing covers all of the egg cap (Baker 1986, as Cuterebra horripilum Clark). It does not look like a plastron similar to that found in the Calliphoridae, nor does it look like aeropyles as found in the Tachinidae. The only SEM-studies of eggs of Gasterophilini (Cogley & Anderson 1983) and Hypodermatinae (Cogley et al. 1981) do not pay spe- cial attention to the egg cap. Too little is known on egg structure in the Sarcophagidae to allow a reasonable scoring of the groundplan. In Miltogramma Meigen, the egg seems devoid of any plastron or aeropylar area (Thompson 1921), but SEM studies are needed to confirm this. 67 TIJDSCHRIFT VOOR ENTOMOLOGIE, VOLUME 135, 1992 In Sarcodexia lambens, the egg is pitted with aeropyles in the posterior third of what may be the dorsal sur- face (Lopes & Leite 1989), while eggs of Sarcophaga, to the extent they are known, only present a single aeropyle, which is situated opposite the micropyle (Baudet 1980, 1985). A true plastron is probably ab- sent in the Sarcophagidae as this would be non-func- tioning during intra-uterine incubation. Character y. — 28s ribosomal RNA sequence data Vossbrinck & Friedman (1989) used sequence data from 28s ribosomal RNA to analyse relationships between selected cyclorrhaphan species. Their data have not been included in the present analysis for the following reasons. Firstly, ribosomal RNA of far too few taxa has been analysed, which would have given this input of character states proportionally more weight than it may deserve. Secondly, and perhaps more important, I prefer to await a consistent metho- dology for phylogenetic analysis of nucleotide se- quence data. Of particular relevance before trans- lating Vossbrinck & Friedman's (1989) table 1 into character states is a discussion of homology between the sequences analysed. However, it is obvious from the cladograms produced by these authors that their sequence data give results that show little congruence with results obtained in the present analysis. Character z. — Parasitism Parasitism of a certain taxon has been used expli- citly as an apomorphic character state for all major parasitic clades of the Tachinidae family-group (Pape 1986a, Rognes 1986, McAlpine 1989). McAlpine (1989: 1501) even stated that being ‘obligate pa- rasites of other animals .... is presumed to be a pri- mary, autapotypic adaption of [Oestridae + Rhinophoridae + Tachinidae] (synapotypic character of the component families)’. An important question, however, is how parasitism fits into a character ana- lysis, i.e. whether or not parasitism really is a char- acter and in case how the states are defined. As I have met numerous viewpoints on this issue in discussions with fellow systematists, a rather detailed elaboration of the problem seems justified. Parasitism per se is here defined with the very broad concept adopted by Price (1980: 4), who simply cites the definition given in Webster's Third International Dictionary: A parasite is ‘an organism living in or on another living organism, obtaining from it part or all of its organic nutriment, commonly exhibiting some degree of adaptive structural modification, and caus- ing some degree of real damage’. Parasitism, then, could be defined as a character with the states ‘developed’ and ‘not developed’. This would imply that, say, the Agromyzidae (parasites of angiosperms) would be scored exactly like the 68 Rhinophoridae (parasites of woodlice) in a family lev- el phylogenetic analysis. This way of handling parasit- ism seems falsified by the very definition of a charac- ter accepted in the present paper, being an inheritable feature that is independent of any other inheritable feature(s). Parasitism per se, as here defined, is not built in as a message in the genetic code. One could elaborate the definition of the states so that states (of, say, life habit) pertaining to parasites were defined taxonomically as the most restricted (= smallest pos- sible) recent taxon assumed to contain the hypotheti- cal ancestral host or host-lineage. Put in a more infor- mal wording, this means that the habit of parasitizing a certain taxon is considered a derived character state for the parasites of this taxon. In this way, parasitism of true bugs (Heteroptera) would be a synapomorphy of the Phasiinae, insect parasitism a synapomorphy of the Tachinidae, mammal parasitism a synapomorphy of the Oestridae, woodlice parasitism a synapomor- phy of the Rhinophoridae, etc. But we still do not have characters or character states in the sense of in- heritable features — organisms simply do not parasi- tize taxa, they parasitize other organisms. This may seem pure epistemology, but parasitism in this taxo- nomic definition can only be defined a posteriori, and corroborating a group of species based on the com- mon habit of parasitizing the same taxon (whether of specific, generic, or any other rank) is unsound. The Pieris -butterflies, for example, do not possess the character state ‘phytophages of Capparales’. They will readily eat any plant containing (or just tasting of) mustard oil glucosides, e.g. members of the Brassicaceae, Tropaeolaceae and some other Capparales, and the real character state should rather be ‘mustard oil glucosides promote larval feeding’ (David & Gardiner 1966) or perhaps even more spe- cific ‘larval maxillary sensilla styloconica with chemo- receptory cells sensitive to mustard oil glucosides’ (Schoonhoven 1967). Taxonomic host data is merely information on the distribution of hosts within the classification available. Modern classifications of host organisms reflect their “descent with modification’, which cannot trigger oviposition behaviour. Thus, in my opinion the monophyly of a group consisting of the Tachinidae + Rhinophoridae cannot be argued on the shared occurrence of parasitism of arthropods simply because arthropod parasitism has no validity as a character state. And if arthropod par- asitism cannot be considered a character state, insect parasitism, wood-lice parasitism or animal parasitism obviously cannot do either. When dealing with still more restricted and/or specialized host taxa, however, one will often increase the probability that its asso- ciated parasites actually do belong to a monophyletic group. This, however, is nothing but 4 posteriori sta- tistics and reflects that many parasite clades in nature really are restricted to one or a few host clades. If parasitism (of a taxon) cannot be considered a character, this implies that even if the Tachinidae and Rhinophoridae constitute a clade one cannot make a straightforward deduction that their common ances- tor was a parasite of either insects or woodlice unless we assume that the transition between woodlouse parasitism and insect parasitism (or vice versa) is more likely than the transition between scavenging and woodlouse/insect parasitism. Only if synapomorphic character states directly relating to the parasitic habit are present can we convincingly argue for a single or- igin of parasitism, and we may then consider wood- louse parasitism to have developed from insect para- sitism (or vice versa) simply because this is more probable than the hypothesis of both habits arising si- multaneously, i.e. in the same speciation event. Wood (1987b: 1189) tentatively suggests one such character: “The tendency to stimulate the formation in the host of [a funnel-like integumental sheath] or at least to use it to advantage for support and respira- tion, may be a synapomorphy of the Rhinophoridae and Tachinidae’. Two problems should be considered in this context. Firstly, of course, one has to decide whether or not to accept the character at all. In my opinion, the formation of a sheath enveloping part of the parasite is a typical immunological reaction that would happen to any foreign body piercing the integ- ument and penetrating into the haemocoel. Thus, the formation of a sheath could be plesiomorphic at this level. No sheath-formation has been reported from hosts of parasitic Sarcophagidae, e.g. the grasshopper- parasitizing Blaesoxipha (Léonide & Léonide 1986), which seem to be independent of direct access to the surrounding atmosphere in at least second and third instar. More tricky is the question whether or not the use of this sheath for support and respiration is a char- acter state, but as the formation of the sheath prob- ably is induced by the piercing of the integument, e.g. a trachea, use of the sheath cannot be considered in isolation. Numerous types of larval equipment for piercing the host's integument may be found in the Tachinidae, but all of these differ from what may be analogous structures in the Rhinophoridae and ap- parently without being related through transforma- tion series. I have not accepted the use of a respirato- ry funnel or any associated feature within Rhinophoridae and Tachinidae as homologous. Another matter is, that if the production within the host of a sheath of host integument, or its being used by the parasite, is considered a (derived) character state, the character would be inapplicable with regard to the Oestridae. Oestrid hosts, i.e. mammals, differ radically from arthropods in cytology, physiology and immunochemistry. A respiratory funnel, therefore, cannot in itself provide evidence that the Pape: Phylogeny of the Tachinidae family-group Rhinophoridae are more closely related to the Tachinidae than are the Oestridae. Note the few but well documented cases of human myiasis produced by tachinid flies that even have resulted in the emer- gence of adults (Smith 1988). This shows that we cannot a priori exclude the possibility that mammal parasitism evolved from insect parasitism. CLADES OF THE TACHINIDAE FAMILY-GROUP Running the present character matrix (table 2) through Hennig86 (version 1.5) with all states unor- dered (outgroup = 0.1;cc-.;mh*;bb*;) results in an initial set of 630 most parsimonious cladograms (length = 111, consistency index = 55, retention in- dex = 77). Subsequent successive weighting (xsteps w;mh*;bb*;xsteps w;mh*;bb*; etc.) reduces these 630 cladograms to 15, although with no changes in fami- ly level relationships. From the resulting Nelson consensus tree (fig. 9), deductions of transformation series between character states can be made for those characters where more than two states are involved (i.e. characters 0, 9, 10, 13, 15, 21, 22 and 39). Characters 0, 9, 13 and 21 may thus be arranged in li- near transformation series, which correspond to the numeral sequences used when listing the states in the discussion above. [Note that transformation series need not be rooted at the lowest number, i.e. ‘0°. Character 13 has the transformation series 0-1-2 but is rooted at 1]. For characters 10, 15, 22 and 39, less straightforward transformation series are involved, and these characters were maintained as unordered (cc-10,15,22,39;). Specifically for the subscutellum (character 10), the cladogram in fig. 9 leads to the assumption that the convex state (2) most probably developed from the concave state (0) in the Tachinidae and from the medium-sized state (1) in the Hypodermatinae, and as the concave state also may have given rise to the medium-sized state as well as vice versa, all states are interconnected and should be treated as unordered. With this new input of phylogenetic information, data were rerun (outgroup = 0: 1sce- 10,15,22,39;mh*;bb*;xsteps w; etc.). This resulted in 30 trees, the Nelson consensus tree of which did not differ from the one resulting from all characters being unordered. This cladogram is the one I consider as the currently most corroborated hypothesis of family- level phylogenetic relationships within the Tach- inidae family-group (fig. 8). Competing cladograms resulting from different character or transformation series interpretations are discussed below (figs. 10, 11), with character states for non-terminal clades in tables 4, 5.

Apomorphic character states have been given a con- cluding composite number (character: state) referring to the discussion of characters and to the data matrix; or a letter for reference to the discussion of unscored characters. Oestridae As pointed out by Wood (1987a), the early con- cept of the botflies as a ‘natural’ (i.e. monophyletic) group has gained wider acceptance after a period with attempts of splitting the group and assigning the fractions to various other calyptrate families or even to the acalyptrates (see Grunin (1969) for references). Although mammal parasitism has evolved several ti- mes in the Calliphoridae and Sarcophagidae, it has never promoted the physiological coevolution shown by the botflies and their hosts. Some species of Wohlfahrtia (Sarcophagidae) and Booponus (Calliphoridae) are subdermal parasites of mammals and at least some species of the latter genus seem to be quite host specific. But the warbles, if any, formed by these species are simple swellings caused by the in- flammatory response of the host. Contrary to the bot- flies, these larval feeding sites often leave a considera- ble scar. NWW KRW D —= Presently recognized botfly synapomorphies are: . Postocular setae reduced (0:2); .

Rhinophoridae The Rhinophoridae have recently been subject to some attention, but despite several attempts at a de- finition based on apomorphic character states in the adult morphology, only the morphology of the first instar larva has provided what seems to be unambi- guous and autapomorphic character states. Crosskey (1977) reviewed the family and provided a thorough discussion of the characters most often used in the characterization of the family. He admit- ted, however, that his recognition couplet for ima- gines still fits “a very few aberrant tachinids’ (p. 7). Tschorsnig (1985a), although including both Melanomya and Morinia, both of which now general- ly are accepted as Calliphoridae, described the struc- ture of the male terminalia in detail and suggested (tentatively) that broadened bacilliform sclerites and a patch of setae anterobasally on the surstylus should be considered synapomorphic for the Rhinophoridae (see his figs. 7-10). Exceptions exist, and as some of these represent undescribed genera (Pape, unpubl.) I prefer to await a revised generic phylogeny with data on this character incorporated before evaluating the rhinophorid groundplan. The phallic character state previously used by me, the fusion of the ventral plates in the median line (Pape 1986a), apparently does not have the diagnos- tic or defining powers stated. Although it may be apo- morphic at the level of the rhinophorid groundplan, numerous homoplasies occur in the Calliphoridae and Tachinidae, and even within the Rhinophoridae reversals to the non-fused condition have to be as- YA: = Anthomyiidae ah Muscidae Bil ie Tachininae Exorista genus-group Es Phasiinae 3 ic Miltogrammatinae 3 6 È IL TG Paramacronychiinae 32-— Sarcophaginae f= Rhinophoridae 403 Oestrinae | rok Hypodermatinae pre la Gasterophilini 27== Cobboldiini L m: = Lo Cobb mule ele Helicoboscinae sl m age nee ay) Te Polleniinae 29-— Mesembrinellinae Ameniinae Phumosiinae Calliphorinae Luciliinae Melanomyinae m Chrysomyinae VE Rhiniinae Toxotarsınae Ar [Tm sumed (Paykullia, several species of Phyto). I do not consider this character any further in this context. Wood (1987b: 1189) clearly pinpointed the current situation when he wrote: ‘no character or group of characters has been found in the adult to render the group recognizable or to suggest that it is monophyletic’. But, on the other hand, the obviously apomorphic larval character states bring substantial evidence that a very well defined monophyletic group exists, and only our sparse knowledge of this stage prevents an easy delimitation of the group. Hence, I cannot agree when Downes (1986: 17) ‘interpret[s the Rhinophoridae] as an intentionally practical rath- er than a natural taxon’ which ‘in practice....is analo- gous to the Fungi Imperfecti’. All species of Rhinophoridae are obligate parasites (or parasitoids), but parasitism of woodlice will not be included as a character state, as already discussed. 1.

[The use of the presence of larval sarcophagine as an apomorphy corroborating the monophyly of the Sarcophagidae is, of course, tentative as too few records exist and especially as no Miltogrammatinae have been tested. But the al- most total absence of this dipeptide from the non-sarcophagid calyptrates is strong evidence that the presence in the Sarcophagidae is derived, and testing one or more species of Milto- grammatinae may indicate whether this character state should be considered autapomorphic for the clade Paramacronychiinae + Sarcophaginae or for all of the Sarcophagidae.] Some of the autapomorphic groundplan character states used by McAlpine (1989) to define the Sarcophagidae are not accepted here and should be discussed briefly: Coiled male accessory glands, scle- rotized plate (sigma) in dorsal wall of uterus, looping of ovarian ducts and common oviduct, and reduced labral sclerite in the first instar larva, are states that de- fine all or part of the subfamily Sarcophaginae. These states are not present in the Miltogrammatinae and Paramacronychiinae and should not be considered groundplan states for the family. Arista bare on at least apical half needs reconsideration as already dis- cussed. If the sister group of the Sarcophagidae is the Tachinidae, a bare arista seems at least as probable for the hypothetical groundplan. Tachinidae The Tachinidae form a huge family and the species have diversified morphologically to an extent not seen in the other families of the Tachinidae family-group. However, apart from some species that are strikingly rhinophorid-like in adult morphology, like Litophasia Girschner, Tachinidae are easily recogni- zed and they emerge as a well defined group of insect parasites.

Calliphoridae The blowflies have generally been recognized among members of the Tachinidae family-group by exclusion of the more easily defined remaining fami- lies, and Griffiths (1982) concluded that no convin- cing evidence corroborated the possible monophyly of the Calliphoridae. Hennig (1973: 69) even mentioned that the Calliphoridae could be paraphy- letic (‘vielleicht eine paraphyletische Gruppe’). In the present analysis the Calliphoridae emerge as mono- phyletic, corroborated by the following character states: 1. Phallus with free tips of dorsolateral processes (32:1); 2. Parastomal bars present (45:0). As already discussed, teeth or spines apically on the free apices of dorsolateral processes may be another synapomorphy (character p), but as long as both the toothed and the non-toothed condition occur widely, an assessment of the groundplan state within each of the terminal taxa requires a better knowledge of the distribution of both states as well as of generic phy- logeny. It is noteworthy that the metallic coloration of the integument cannot be considered apomorphic at the level of the Calliphoridae. Either this character state is synapomorphic for Calliphoridae and Oestridae, or it will define a subgroup of Calliphoridae, i.e. by exclu- sion of at least the Helicoboscinae. McAlpine (1989) mentioned several tentatively ap- omorphic character states, but most of these need re- consideration. A coprophagous larval food habit is hardly ‘autapomorphic’ in the Calliphoridae, and even McAlpine himself did not really believe this as he used this state to corroborate the monophyly of his clade Calliphoridae + Mystacinobiidae + Sarcophagidae. It is worth noting that coprophagy in the Calliphoridae may not be plesiomorphic either, as none of the basal calliphorid lineages in the present cladogram (fig. 8) are typical coprophages. Rognes (1991: 27) is of the opinion that blowflies ‘primitive- ly … lay their eggs on the exposed dead bodies of var- ious animals, especially vertebrates, irrespective of size’, but I find it very likely that the groundplan cal- liphorid breeding strategy was one of small-carrion- exploitation, e.g. dead invertebrates (especially snails) and small vertebrates. This is in agreement with the arthropod and mammal parasitism of the Rhinophoridae, Tachinidae and Oestridae, which has to have evolved from a non-parasitic life habit. The hypothetical ancestors of these taxa could easily have preferred small carrion: invertebrates for the 77 TIJDSCHRIFT VOOR ENTOMOLOGIE, VOLUME 135, 1992 Rhinophoridae and Tachinidae, rodents for the bot- flies. "Thoracic spiracles large’ is closely connected to the size of the fringes, which has been discussed in de- tail above (character 13: state 2). Whether or not large size of spiracle (or anterior fringe) belongs to the groundplan of the Calliphoridae depends on the po- sition of the Helicoboscinae. The ‘posterior thoracic spiracle occluded by ... complex shutters’ is obviously a groundplan feature of all of the Tachinidae family- group, as was correctly stated by Crosskey (1977: 8), although this author did not mention the Oestridae. ‘Arista plumose’ needs a more accurate scoring, but may well be synapomorphic with the Oestridae. Position of female abdominal spiracle 7 needs further consideration through scoring of more species from what may be considered basal lineages, and the pres- ence of ‘anal lobes’ in the male perianal membrane may belong to the groundplan of the Tachinidae fam- ily-group. Other groundplan features have been dis- cussed above. Calliphoridae + Oestridae 1. Prosternum setose (5:1); 2. Proanepisternum setose (6:1); [3. Postalar wall setose (7:1);] 4. Metasternum setose (8:1). The third character state is given in brackets as its status as a synapomorphy for Calliphoridae and Oestridae is uncertain. The bare and the setose states are equally likely for the groundplan of this clade. It may, perhaps, be argued that an independent origin of setae on this surface is less likely than independent reductions. Sarcophagidae + Tachinidae 1. Phallic dorsolateral processes fused (34:1). Fused dorsolateral processes were used by Pape (1987a: 11) to corroborate the monophyly of the Sarcophagidae, but Tschorsnig (1985b) argued con- vincingly that the dorsal (or posterior) phallic sclerot- ization so common and widespread in the Tachinidae is homologous to fused dorsolateral processes. The character state will therefore indicate phylogenetic re- lationship. Rhinophoridae + (Calliphoridae + Oestridae) 1. Subscutellum slightly swollen (10:1). This synapomorphy is, of course, highly dependent on the scoring of subscutellar states, as will be dis- cussed in more detail below. 78 Tachinidae family-group Only two outgroups were used in the present stu- dy, Anthomyiidae and Muscidae. As these may be part of a separate clade, the Muscoidea of McAlpine (1989), the present analysis cannot give a reliable esti- mate of whether ground plan character states at the level of the Tachinidae family-group are apomorphic or plesiomorphic. Therefore, the states listed below as probably synapomorphic for members of the Tachinidae family-group may be tested when a more detailed phylogeny of all of the Calyptratae becomes available. However, in my opinion none of the states listed below can be ascribed to the groundplan of any non-tachinoid family of Calyptratae. 1. Postocular setae of alternating size (0:1); 2. Meron with row of setae (9:1); 3. Anatergite with setulae (11:1); 4. Metathoracic spiracle with divided (opercular) fringe (12:1); 5. Anepimeron with setae (14:1); 6. VeinM with a distal angular bend (15:2); 7. Vein R,,; setose basally (20:1); 8. Lower calypter broad and following scutellum for considerable distance (21:2); 9. Abdominal sternite 2 contiguous with or slightly overlapped by margins of tergite 1+2 (22:1); 10. Spermathecal ducts join uterus separately (25:1); 11. Gonostylar apodeme present (30:1); 12. Phallus with denticles along the ventral surface of distiphallus (31:1). Mystacinobia The single New Zealand species of this peculiar taxon, M. zelandica Holloway, is highly adapted to living in bat roosts and the morphology leaves few ap- parent clues to phylogenetic relationships. Originally described as a distinct family Mystacinobiidae belon- ging to the Drosophiloidea (Holloway 1976), Griffiths (1982) argued convincingly for an inclusion in the Tachinidae family-group and proposed syno- nymization with the Calliphoridae although no sy- napomorphic character states with this family were suggested. Kurahashi (1989) accepted an assignment to the Calliphoridae and put Mystacinobia in a subfa- mily of its own. McAlpine (1989: 1500) recognized an affınity between Mystacinobia and the Calliphoridae but en- dorsed family rank for the genus because it possesses ‘many autapomorphies in all stages .... that set it apart from all Calliphoridae’ — in my opinion a little con- vincing argument. Furthermore, McAlpine's clado- gram (Mcalpine 1989: fig. 116.8) corroborated the monophyly of the non-mystacinobiine blowflies (his Calliphoridae) by listing the synapomorphies 1) first larval instar without paired mandibles, 2) arista plu- mose, and 3) testes enveloped in fat body. The first state was based on Hennig (1973) and is erroneous as already mentioned. The second apomorphy is dubi- ous and actually contradicted by McAlpine himself on p. 1501, where he stated that a plumose arista is present in the calliphorid + sarcophagid groundplan. The third synapomorphy is hardly more convincing as no mention is made of the actual distribution of this character state, and Hori (1960), who first used this character, examined only very few representatives of Calliphoridae. Even if fresh or properly preserved specimens of Mystacinobia were examined by McAlpine, we are still in need of data from many oth- er members, especially from the Oestridae and Rhinophoridae, and from possibly basal calliphorid lineages like the Helicoboscinae. McAlpine listed more calliphorid autapomorphies in the text (p. 1499), but none of these will corroborate a separate family status for Mystacinobia. The non-mystacino- biine calliphorids cannot be defined by being co- prophagous when their sister group is stated to be ‘liv- ing in [bat] guano’ (p. 1500) and when coprophagy is listed as a groundplan feature of Sarcophagidae + Mystacinobiidae + Calliphoridae (fig. 116.8). Indeed, Mystacinobia is highly aberrant, and as on- ly a single species is involved, monophyly as such is ir- relevant. A list of autapomorphic character states is given by McAlpine (1989) and needs not be discussed here. Griffiths (1982) gave three character states of Mystacinobia that will corroborate its assignment to the Tachinidae family-group: 1) 8th sternite of fe- male entire, 2) phallus with denticles on ventral sur- face of distal section, and 3) meron with row of setae below metathoracic spiracle. To these could be added the presence of anepimeral bristles (character 14 in the discussion above). Many more characters are in- volved in the definition of the Tachinidae family- group, but several of these are wing-characters and therefore inapplicable, which probably holds also for the infrasquamal setulae (character 11). Thus, only four characters need a comment. Postocular setae are hardly recognizable in Mystacinobia, and the great re- duction in eye-size and the deviating head-shape makes this character inapplicable. Abdominal ster- nites, in their degree of exposition, may be more like the condition found in the Oestridae than that of any other taxon here considered, and it is thus perfectly possible — even probable — that it is derived relative to the groundplan of the Tachinidae family-group. The small metathoracic spiracle of Mystacinobia has no fringe at all, and could thus easily be considered as de- rived from any of the conditions found in the Calyptratae. Moreover, it is almost to be expected that a flightless species living in the constantly damp atmosphere of a bat roost should show modified Pare: Phylogeny of the Tachinidae family-group metathoracic spiracles, as this is one of the major sites for loss of water in a flying calyptrate fly. Finally, no gonostylar apodeme is present, and this may in itself be taken as evidence of a sister group relationship with the remaining Tachinidae family-group. However, other reductions are present in the male copulatory apparatus, e.g. small gonocoxites and ab- sence of epiphallus, and it seems somewhat premature to assign familial status to Mystacinobia — not to men- tion a sister group relation to the (remaining) Tachinidae family-group — based exclusively on this sparse evidence. With regard to familial affinities, an inclusion within any of the Oestridae, Rhinophoridae, Sarcophagidae and Tachinidae seems highly improb- able as this would imply that Mystacinobia should have lost the numerous character states defining these clades. Also, I have no convincing evidence that Mystacinobia should belong to any subfamilial clade within any of these families. Inclusion within the Calliphoridae cannot be corroborated either. Mystacinobia does not possess any of the two charac- ter states here listed as synapomorphies for the Calliphoridae, namely parastomal bars and free tips of dorsolateral phallic processes, and there is no obvi- ous calliphorid subfamily with which it could be affil- iated. Still, however, the spermathecal ducts are of the “two fused’ condition (see character 25 above), which is absent from all of Rhinophoridae, Sarcophagidae and Tachinidae. In the present analysis this character defines a large subgroup of the Calliphoridae, namely all subfamilies except Helicoboscinae and Bengaliinae. The dorsolateral processes are fused as in the clade Sarcophagidae + Tachinidae and as in the Rhiniinae of the Calliphoridae. However, no other evidence fa- vours an inclusion in either of these groups, and no member of the Rhiniinae has yet been reported from New Zealand (Dear 1985). I have not included Mystacinobia in the analysis at the present state of knowledge. A strict scoring would hardly give a reliable result and would rather interfere with the not too stable phylogeny presented. Therefore, I will simply consider Mystacinobia as a ge- nus (and species) incertae sedis within the Tachinidae family-group. Until a better corroborated hypothesis for the inclusion within one of the existing taxa, or for a sister group relationship to one or more of the oth- er families is available, I prefer to avoid using a fami- ly group name to accommodate the species. Discussion An interesting — although hardly surprising — result of the present analysis is that the monophyly of all fa- milies except the Calliphoridae is well corroborated. 79 TIJDSCHRIFT VOOR ENTOMOLOGIE, VOLUME 135, 1992 The monophyly of the Calliphoridae is supported by few, and perhaps not very convincing synapomor- phies, and the family may even come out as polyphy- letic with regard to the Helicoboscinae under certain circumstances, which are discussed below. Also inte- resting is the surprisingly few derived character states that define suprafamilial clades, and it is noteworthy that none of these states have been used previously in corroborating inter-familial phylogenetic relation- ships. We simply have no conclusive evidence on any sister group relationship at the family level within the Tachinidae family-group. As a consequence of this li- mited evidence, of course, the cladogram favoured here is far from stable. Reinterpretations of characters and/or the addition of new characters by future stu- dents are highly encouraged to test the present hypo- thesis. In the Calliphoridae, presence of parastomal bars is a very consistent character state in the sense that ho- moplasic occurrences are virtually non-existent. I know of no calliphorid larva without parastomal bars in the third instar, except for Mystacinobia if evidence can be found that corroborates an inclusion in the Calliphoridae. Parastomal bars do not occur at all in the Tachinidae, Rhinophoridae and Oestridae. It is interesting, however, that presence of parastomal bars generally has been considered plesiomorphic in the Calyptratae, e.g. by McAlpine (1989). The free tips of dorsolateral phallic processes was used by Rognes (1986, 1991) to unite the Rhinophoridae and the Calliphoridae; with the Rhinophoridae as a subfamily, but not necessarily as a sister group of the remaining Calliphoridae. As al- ready discussed, I have been unable to score the groundplan of the Rhinophoridae for this character, which in combination with its inapplicability with re- gard to the Sarcophagidae and Tachinidae (see below) really leaves it with very limited diagnostic power in the present analysis. Thus, it is interesting to note that if the Rhinophoridae are scored for free tips of phallic dorsolateral processes in the matrix (i.e. Rhinophoridae are scored for 1 in character 32 of ta- ble 2), and if this is run as discussed above (outgroup = 0.1;cc-10,15,22,39;mh*;bb*;xsteps w; etc.), the re- sulting consensus tree will depict the Oestridae as the sister group to the remaining Tachinidae family- group and the Helicoboscinae as the sister group of a clade Sarcophagidae + non-helicoboscine Callipho- ridae (fig. 10). Scoring the Rhinophoridae for the al- ternative state; namely dorsolateral processes conflu- ent with phallic wall (0 in character 32 of table 2), has no impact on the configuration of the resulting Nelson consensus tree. The clade Calliphoridae + Oestridae is corroborat- ed by three character states with the possible addition of a fourth. These states are presence of setae on well- 80 defined thoracic surfaces, which have been used wide- ly in the diagnosis of the Calliphoridae. They have probably been overlooked or neglected in the Oestridae because of the long, dense hairs, which tend to conceal the thoracic sclerites. Only one character state, the fusion of phallic dor- solateral processes, corroborates the monophyly of the clade Tachinidae + Sarcophagidae. This fusion complicates the assessment of at which level in the cladogram the free-tipped dorsolateral processes are apomorphic. I have argued that the dorsomedian fu- sion of these phallic sclerotisations makes a scoring for presence/absence of free tips inapplicable. With the condition in the Rhinophoridae being uncertain, this will imply that the possibility of free tips being a groundplan state of the Tachinidae family-group can- not be excluded. In the analysis, this would be equal to omitting this character (outgroup = 0.1;cc- 10,15,22,39;cc]32;mh*;bb*;xsteps w; etc.). This re- sults in the Sarcophagidae being the sister group to the remaining Tachinidae family-group and the Cal- liphoridae become polyphyletic as the Helicoboscinae move to a sister group position of Oestridae (fig. 11). The monophyly of the clade Rhinophoridae + Calliphoridae + Oestridae is corroborated by a single character state: presence of a slightly swollen subscu- tellum. This is indeed weak evidence as the present division of subscutellar shape in three states may be too simplified. Differences between the various types, however, are not easy to put on formal descriptive terms. If the slightly swollen subscutellum seen in the Rhinophoridae, the botfly subfamilies, and some of the calliphorid subfamilies are considered as derived independently in each terminal taxon, this character will have no effect on interfamilial phylogeny and could as well be excluded from the matrix. This exclu- sion (outgroup = 0.1;cc] 10;cc-15,22,39;mh*;bb*;- xsteps w; etc.) results in a cladogram identical to that of fig. 10, with the Oestridae being the sister group of the remaining Tachinidae family-group. This will happen irrespective of how the Rhinophoridae are scored with regard to free or confluent tips of dorso- lateral processes. Even the ordering of the subscutellar states is open to discussion. As already discussed, I prefer to avoid ordering these states as I have no reason to consider the swollen condition of the Tachinidae to have aris- en from a less swollen condition rather than from the concave condition. If, however, these states are put in a linear transformation series with increasing convex- ity (i.e. 0-1-2), and if all characters but 15, 22 and 39 still are treated as ordered (outgroup = 0.1;cc- 15,22,39;mh*;bb*;xsteps w; etc.), the resulting clado- gram will again put the Oestridae as the sister group to the remaining Tachinidae family-group (fig. 10). These examples are excellent illustrations of the importance of character and transformation series interpretation. It should be obvious from the discussion above that inter-familial phylogenetic relationships within the Tachinidae family-group still are open to consider- able discussion. While the monophyly of the non-cal- liphorid tachinoids are becoming better and better corroborated we are still short of a satisfactory defini- tion of the Calliphoridae. However, the main prob- lem relates to the position of the subfamily Helicoboscinae (currently with the single genus Eurychaeta), as the large size of the metathoracic spir- acle (or its fringe) provides a character state consist- ingly uniting all non-helicoboscine blowflies. It should also be emphasized that the present study is insufficient in the sense that several characters have been excluded from the analyses because of uncertain- ty with regard to their proper scoring. Presence in Eurychaeta of intrapostocular setulae and divided fe- male abdominal tergites 7-8 (characters b, h) may provide important additional support for a mono- phyletic Calliphoridae when included. What should be given high priority in future stud- ies is a better definition of the Calliphoridae. Important information may be obtained through bet- ter definitions of subfamilies as well as through pat- terns of subfamilial relationships. Also the Rhinophoridae need a closer examination. Their def- inition relies heavily on larval characters, which are known for less than half the included genera, and our present ignorance of generic phylogenetic relation- ships for genera like Bezzimyia and Malayia makes groundplan estimates of certain characters ambiguous within this family. Inclusion of additional outgroups will be a proper test of the hypothetical groundplan of the Tachinidae family-group outlined in this study. Thus, studies on the phylogenetic relationships of the non-tachinoid calyptrate families are needed, and if McAlpine's (1989) hypothesis of a monophyletic Muscoidea finds additional support, outgroup information should be obtained from the Hippoboscidae family- group and/or from the Acalyptratae. ACKNOWLEDGEMENTS I extend my most sincerest thanks to Knut Rognes, Stavanger, who spent much time reading and critizising previous drafts of the manuscript. His most valuable comments and suggestions are highly appre- ciated, and although the final decisions and con- clusions regarding interpretations of characters and character states are entirely mine, there is no doubt that the paper has improved considerably through his effort. Monty Wood, Ottawa, and Stig Andersen, Pape: Phylogeny of the Tachinidae family-group Copenhagen, contributed with significant infor- mation on various aspects of tachinid phylogeny and morphology, and Verner Michelsen, Copenhagen, gave important information on the Anthomyiidae and Muscidae. Amnon Freidberg, Tel Aviv, kindly arranged a loan of the undescribed species of Mexican Bezzimyia, and Norman E. Woodley, Washington, D.C. and Beverly A. Holloway, Auckland, generous- ly provided some specimens of Mesembrinellinae and Mystacinobia zelandica respectively for examination. Thanks also to Brian M. Wiegmann, Maryland University, for taking time to discuss the use of pa- rasitism in phylogenetic analyses. The present study was supported in part through grant No. 11-6152 from the Danish Natural Science Research Council. REFERENCES Allen, H. W., 1926.

Key words. — Feather mite, Xolalgidae, parrot, Psittacidae, uropygial gland tuft. Ontogenetic studies of astigmatid mites are limit- ed. To add to the meager information on this subject, I am associating all instars of seven species of the feather mite genus Fainalges Gaud & Berla, 1964 (Xolalgidae) from field collected specimens of the green conure, Aratinga holochlora (Sclater), taken in Tamaulipas, Mexico. The most demanding part of this and similar onto- genetic studies is to unequivocally associate feather mite larvae with their eggs. To do this, it is necessary to dissect fully developed larvae from their eggs for microscopic examination. In the Fainalges investiga- tion, the larvae of six species had been identified and associated with their eggs, but the egg of a seventh lar- va, a new species near Fainalges longissimus Mejia- Gonzälez & Perez (1988) remained undetected until a small group of specialized feathers were examined, namely, the uropygial gland tuft. Herein, this special- ized microhabitat and their acarine occupants will be described MATERIALS AND METHODS Uropygial gland papillae were taken from two frozen, field collected Aratinga holochlora. The tuft feathers were excised, the quills split lengthwise and the quill contents either mounted on SEM stubs or microslides. To obtain mature larvae for identifi- cation, eggs were taken from the barbs and opened, either on an SEM stub or in a small drop of Hoyers mounting medium. Thus, correlation of eggs and larvae were established. Additional specimens for on- togenetic studies were obtained from samples taken from approximately 30 museum study skins. Dissections and measurements of the feathers were done with a dissecting microscope equipped with an ocular micrometer. Identification of the mite life stages was with a Wild-Heerbrugg M-20 phase con- trast microscope and specimens for electron scanning microscopy were gold-coated and examined with an Amray 1000 SEM. Uropygial gland papilla and associated feathers The uropygial gland (oil gland, preen gland, rump gland) is positioned dorsomedially in the tail region of a bird. When present and functional, the bilobed gland is usually indicated by an elevation of the skin, the uropygial eminence, from which a terminal papil- la arises; the papilla usually contains two ducts ope- ning to the exterior at its tip. The papilla is variously shaped and may have a cluster of modified down or modified semiplumes, termed the uropygial gland tuft or circulus uropygialis, surrounding the openings of the uropygial gland ducts; the tuft feathers are in different numbers and arrangements according to group (Lucas & Stettenheim 1972, Jacob & Ziswiler 1982: table 1, Johnston 1988). Tuft feathers have un- usually large quills and relatively short barbs when compared to typical down feathers. In Aratinga holochlora the papilla is cylindrical (3.6 87 ‘TIJDSCHRIFT VOOR ENTOMOLOGIE, VOLUME 135, 1992 mm in length, 2.2 mm in diameter, N=1) and the uropygial gland tuft (barbs only, 7.9-9.4 mm, N=2) is arranged as a single oval of eight modified down feathers around the duct orifices. The tuft is saturated with uropygial gland secretions, but when degreased it resembles an airgun dart as all diverging barbs end at the same level (Type I of Johnston 1988). Each uropygial gland feather lacks a rachis and hyporachis (aftershaft), and the barbs arise directly from the upper rim of the calamus at the skin level (figs. 1, 2). The calamus (approximately 3.0 mm, N=12), com- pletely embedded in the skin, is a tubular structure (fig. 1) filled with pulp caps. The eight quills form a rosette around the apex of the papilla. The distal end of the quill may represent the superior umbilicus, and as mites can enter, the umbilicus must be open. By being open, each quill probably contains uropygial gland secretions (sebum) and can provide a refuge for organisms unaffected by these secretions. Fainalges and the uropygial gland tuft When studying the biology of the seventh Fainalges species mentioned above, all active instars were observed on the down barbs of the tail coverts, but neither eggs nor exuviae were noted. In previous studies of the feather mites of parrots, it had been de- termined that for some mite species, different instars occur in different microhabitats (e.g. Perez & Atyeo 1984, Atyeo & Perez 1988). Therefore, the feathers above and below the tail coverts were examined, but again, neither eggs nor exuviae were discovered. The only feathers never examined were those of the uro- pygial gland tuft, a microhabitat that was never consi- dered a viable candidate for mite habitation as it has been thought that the uropygial gland secretions inhi- bit parasites (e.g. Jacob & Ziswiler 1982). So, a tuft was excised and examined under a dissecting micro- scope. At the bases of the barbs and surrounding pa- pillary skin, detritus could be seen, but under higher magnification, the ‘detritus’ consisted of masses of eggs, egg shells and exuviae. Eggs (fig. 2) and imma- tures were observed on the barbs. Furthermore, the eight quills of the tuft, examined through the translu- cent papillary skin, appeared dark brown, a color con- dition of quills containing feather mites. Individual feathers and surrounding papillary tis- sue were removed and quills split longitudinally (fig. 1). Within each quill there was a compact plug of ma- terial which, when removed, revealed densely packed and haphazardly arranged exuviae, pharates and ac- tive stages for all immature instars partially covered with uropygial gland secretions (fig. 3). The density of mites within a quill varied. When few mites were observed, limited numbers occupied the more distal interspaces between the pulp caps, up to 4/5 of the distal quill. Some quills were so packed 88 with mite material that the pulp caps were no longer evident. These compact masses (plugs) always over- flowed the quill interior, to form a mound of detritus’ external to the quill proper. The lengths of the plugs varied from quill to quill in the same bird. From 30 museum study skins and eight field col- lected Aratinga holochlora, the active stages of this new species have been known for four to five years, but neither oviposition nor moulting sites had not been described until now. On a related host species, the orange-fronted conure, A. canicularis (Linnaeus, 1758), the active instars of Fainalges longissimus were described from a single microhabitat, the downy barbs of the tail coverts (Mejia-Gonzälez & Pérez 1988), but oviposition sites were not studied. From the information obtained from mites of Aratinga holochlora, it was hypothesized that the uro- pygial gland tuft is the oviposition and ecdysial site for Fainalges longissimus and related species on other parrot taxa. For a preliminary test of the hypothesis, a tuft was removed from one specimen each of Aratinga canicularis and a related taxon, the Carolina parakeet, Conuropsis carolinensis (Linnaeus, 1758), which has been extinct since the 1920s. RESULTS Each quill of the uropygial gland tufts examined from Aratinga holochlora, A. canicularis and Conuropsis carolinensis had at least small populations of Fainalges species in all tuft feather quills and many barbules had Fainalges eggs cemented to them. Each host species supported a different species of the Fainalges longissimus morphotype. This morphotype, as characterized by Mejia-Gonzälez & Perez (1988), has all instars with leaflike ventral setae on tarsi I and II (fig. 6), and in immatures and females, tarsi III and IV have many spinelike setae, minute ambulacral discs, and ambulacral stalks longer than the corres- ponding tibiae (fig. 4). Fainalges longissimus is asso- ciated with Aratinga canicularis, whereas A. holochlo- ra and Conuropsis carolinensis each support a new species of the F. longissimus species complex. Discussion The probable scenario for these species of Fainalges is: females oviposit on bases of the barbs, the barbules of the tuft feathers (Fig. 2) and on the papillary skin; the emerging larvae move to the downy barbs of the tail coverts for feeding; and eventually go to a uropy- gial gland quill for moulting. Each successive instar has the same activity, that is, emerging from the quill, feeding, and then returning to the quill for ecdysis. Because of the out-of-quill sites for the active instars, it is assumed that the uropygial gland secretions with- PÉREZ: Feather mites of Aratinga holochlora esky ToeU 120 10260 MCZ Figs. 1-6.

Three questions need to be addressed: Is there a re- lationship between the moult of the uropygial gland tuft feathers and populations of feather mites? Does preening reduce the mite populations of these mites? Do undiscovered species of the Fainalges longissimus morphotype have the same modus operandi vis-a-vis oviposition and moulting sites? The literature does not specifically answer the question of whether or not the old gland feathers moult. Even so, it is assumed that these feathers do moult as populations of mites within the quills vary, which also suggests that these feathers moult at differ- ent times. The previously reported microhabitats of feather mites on the external feather surfaces relate to the channels created by adjacent barbs, usually on the ventral feather surfaces (e.g., Dubinin 1951, Atyeo & Pérez 1988). Thus, these mites live in a three-dimen- sional space bounded by ramal walls laterally and bar- bules dorsally or ventrally; this space affords protec- tion from the bills of preening birds. Depending on the type of uropygial papilla, sebum for preening is obtained by various methods, ‘either directly from the drops passing out of the [gland] ori- fices or by drawing away the fluid from the tuft circ- let feathers’ (Jacob & Ziswiler 1982: 252). As regards the uropygial gland tuft in Aratinga species, these par- rots probably ’… take the sebum by brushing its beak along the tuft whenever it needs it’ (Jacob & Ziswiler 1982: 252). With this suggested type of preening, it is doubtful that many mite eggs or active instars would be dislodged or destroyed. Do species related to Fainalges longissimus oviposit and ecdyse in the uropygial gland feather quills? The genus Fainalges has never been revised, however, dis- tinct morphotypes are known (Mejia-Gonzalez & Pérez 1988). The F. longissimus type, restricted to New World parrots, was characterized as having all instars with leaflike ventral setae of tarsi I and II (fig. 6), and in immatures and females, pretarsi III and IV (fig. 4) with many spinelike setae, minute ambulacral discs, and ambulacra longer than the corresponding tarsi (Mejia-Gonzälez & Pérez 1988). The F. longissi- mus morphotype is now known from three species of 90 the Aratinginae (sensu Wolters 1975), therefore, it is probable that this morphotype will be found on oth- er New World Aratinginae, and possibly on other parrots with tufted uropygial gland feathers.

Cook (1986) is the most comprehensive work on Australian water mites published so far. Of 263 spe- cies treated by him, 203 were described as new. Since then various studies of Australian water mites were published by Harvey (1987, 1988a-c, 1989a-b, 1990a-d), Harvey & Cook (1988), and Smith & Harvey (1989), all dealing with a limited number of genera or families. During a trip to New South Wales and Queensland in the austral winter of 1989, the present author was able to collect water mites at 46 locations, including lentic as well as lotic habitats. The material was col- lected by using a dip net and preserved in Koenike's solution. All material, including the holotypes, is de- posited in the collection of the Institute of Taxonomic Zoology of the University of Amsterdam (Zoological Museum). Localities are summarized in appendix 1. SYSTEMATIC PART The terminology of Cook (1974) is followed for the description of the species. For a number of species (especially the genera Flabellifrontipoda, Frontipoda and Oxus), without external sexual characters, the sex has not been determined when not necessary for identification.

Discussion. — The long and narrow posteromedial portion of the fourth coxae and the form of the dorsal plates are diagnostic. As stated by several authors (e.g. Cook 1974), subgeneric classification of the genus Hydrachna is somewhat arbitrary. The H. palustris male could be assigned to the subgenus Hydrachna, but the female shows the characters of Diplo- 91 TIJDSCHRIFT VOOR ENTOMOLOGIE, VOLUME 135, 1992 Figs. 1-5.

Hydrachna (Rhabdohydrachna) approximata Halik, 1940 The species has been reported before from West Australia and Victoria (Halik 1941). Material examined. — New South Wales: 1 d, loc. 43. Hydrachna sp. Lundblad (1941) described Hydrachna lateriscuta, but later (1948) placed this species into synonymy of Hydrachna bilobata Halik. Cook (1986) found his specimens of H. bilobata to be in good agreement with Halik's type material, but discovered differences between the material described by Lundblad (1948) as H. bilobata and his own (and thus Halik's) materi- al of that species. Cook (op. cit.) thus suggested that H. lateriscuta Lundblad is a distinct species. Three fe- male Hydrachna specimens collected in the present study agree with the description of the female of H. bilobata presented by Lundblad (1948) and Cook (1986) and tentatively considered as H. lateriscuta by Cook. As no males were found, the three females are left unnamed until the taxonomy of the species con- cerned is better understood. The three specimens are larger than the female collected by Cook. Body length varies from 2280 to 2424 u. Measurements of dorsal plates (length/width) are also larger, 816/1080 u; 768/1008 u and 840/1008 u respectively.

DD EP locw2 8. 92 Eylais Latreille Australian Zylais species were described by Rainbow (1906), Lundblad (1948), Szalay (1953) and Viets (1980). As the variation in morphological characters is rather extensive, taxonomical problems within the genus Eylais remain. Lundblad (1948) stated that (in translation) ‘the Australian Eylais-spe- cies seem to vary highly like everywhere in the world, and it is difficult to find two specimens which are completely alike’. Nothing is known about the va- riation of the Australian species, and it seems to me that a number of species are based on highly variable characters, e.g. the eye-bridge.

Pseudohydryphantes Viets Pseudohydryphantes aroona Harvey, 1988 (figs. 6-10) The species is known from the holotype only, a male collected in a stream in Victoria. The specimen in this study is a female, and a description is given be- low. Female: Body 902 u in length and 630 u in width, lateral side of body undulating. Integument papillate. Dorsally with 6 pairs of dorsoglandularia and 5 pairs of lateroglandularia; sclerites associated with glandu- laria crescent shaped. Lateral eyes on ocular tubercles. Median eye between dorsoglandularia 2 on a small sclerite. Chelicera of normal size, each with a number of short teeth. Ventrally with 5 pairs of ventroglandu- laria. Coxae in four groups, tips of first, second and third with thickened setae. Three pairs of acetabula, two anterior pairs elongate and third pair of acetabu- la rounded. Genital flaps with long setae on mesal edge; genital field 184 u in length. Dorsal lengths of palp segments: PI 46 u, PIT 91 u, PHI 62 u, PIV 139 u, PV 34 u; PIII with convex dorsal and ventral mar- gins. Dorsal length of leg segments: I-leg-1 60 u, I- leg-2 79 u, I-leg-3 89 u, I-leg-4 127 u, I-leg-5 151 u, I-leg-6 156 u; IV-leg-1 120 u, IV-leg-2 98 u, IV-leg- 3 130 u, IV-leg-4 211, IV-leg-5 214 u, IV-leg-6 175 U. Legs III and IV with swimming setae. Claws with- out serrations, but with a short dorsal tooth. Discussion. — The enlarged sclerotisized rings sur- rounding the median eye, preocularia and postocular- ia, the crescent shaped dorsoglandularia sclerites and the position of the median eye between dorsoglandu- laria 2 are diagnostic for the species. The palp of the female is stockier compared with the male.

Oxus orientalis Walter, 1915 With the exception of being larger, the specimens collected agree with the description by Cook (1986). Males vary from 795-863 u (Cook: 684 u), females from 863-1392 u (Cook: 851-972 u). The male from New South Wales is 688 u in length. The specimens of Walter (1915) measure 1500 and 1050 u. Cook (op. cit.) collected only one male and two females, ap- parently small specimens. Males and females differ in length of the long seta on tip of IV-leg (up to 120 u in length), and in the form of the coxae near the gen- ital field. The species was described from New Caledonia.

Material examined. — Queensland: 1 9, loc. 27. Australiobates linderi Lundblad, 1941 (figs. 17-19) Specimens from three locations are provisionally assigned to A.linderi. Specimens from loc. 7, loc. 42 and some males from loc. 40, however, lack setae on the ventral side of PII. This segment has a ventral margin which is almost straight, slightly convex or convex, similar to fig. 33B of Lundblad (1948). Palp segments and leg segments are rather stocky, like A. emalus Cook, which is known from one male only. However, the ventral margin of PIII in A. emalus is straight. The peg-like setae of PIV are bluntly and/or sharply pointed (this character being variable within a single specimen), so this is not a good character. Some measurements are provided here of specimens from loc. 7. Male: Dorsal lengths of palp segments: PII 82 u, PIII 120 u, PIV 108 u, PV 36 u.

Description Male: Dorsal and ventral shields present. Dorsal shield complete, 591 u in length, 543 u in width and with six pairs of glandularia each lying on a small platelet, together with the associated seta. Genital field 145 u in length and 78 u in width. Three pairs of acetabula, anterior pair separated from the others. Fourth coxae with small posteromedial projections. Glandularia of the fourth coxae shifted onto the third coxae. Dorsal lengths of palp segments: PI 26 u, PII 94 u, PHI 77 u, PIV 120 u, PV 38 u. Female: Unknown Etymology. — The species is named for its complete dorsal shield. Discussion. — This is the fifth known Aspidiobates species with a complete dorsal shield. Viets (1969) described two species from New Caledonia and Hopkins (1975) described one species from New Zealand. The only known Australian species with a complete dorsal shield, A. bidewel Harvey, exhibits sexual dimorphism in IV-leg-4. The form of the dor- sal shield and the genital field distinguish the new species easily from the other Australian Aspidiobates species.

Legs without swimming setae. Male. — Unknown. Etymology. — The species is named after Dr. D. R. Cook. Discussion. — Females of the new species differ from those of the two known species of the genus Kallimobates in the form of the palp. The projection on PIII is intermediate between K. australicus Viets (almost without a projection on PIII) and K. vietsi Cook (with a large projection on PIII). The capitu- lum is similar to that of K. vietsi. PIV is rather short, as in K. australicus.

Type species. — Unionicola (Australionicola) ham- meni sp. n. Discussion. — The sexual dimorphism found in the male palp is not found in any other subgenus of Unionicola (see Vidrine 1986, 1987). Also the large claws with 3-4 clawlets are unique for the subgenus, although subgenera (e.g. Anodontinatax) with large, bifid claws do occur. 99 TIJDSCHRIFT VOOR ENTOMOLOGIE, VOLUME 135, 1992 Unionicola (Australionicola) hammeni sp. n. (figs. 27-34) Type material. — Holotype male: Cattle pond Upper Daintree Road, Daintree, Queensland (loc. 32). — Paratypes: One male and one female from same location as holotype. Description Male: Body soft, 592 u in length and 359 u in width; eyes large. Apodemes of anterior coxae exten- ding to third coxae. Epimeroglandularia 2 small. Two acetabular plates (which are possibly fused anteriorly, but this is difficult to determine) each with 5 aceta- bula, the anterior two acetabula of each side and the posterior three acetabula arranged one behind the other; each acetabular plate with two setae. (The slide of the type specimen is of poor quality, so the illust- ration of the ventral side (fig. 27) is of the paratype). Gonopore 107 u in length. Dorsal lengths of palp segments: PI 17 4, PII 103 p, PIII 60 p, PIV 70 u, PV 72 u. Fourth palp segment with two small tuber- cles on posterior margin. Fifth palp segment with a large, stiff lateral seta and a large claw-like structure. Dorsal lengths of fourth leg: IV-leg-2 94 u, IV-leg-3 101 u, IV-leg-4 125 u, IV-leg-5 163 u and IV-leg-6 134 u; IV-leg-6 relatively short, with a small claw without clawlets. All other legs with large claws and 2-3 clawlets. There are two types of long setae present: broad setae which probably act as swimming setae (and here referred to as swimming setae) and long, hair-like setae. I-leg-4 with 4 hair-like setae, I- leg-5 with 5 swimming setae; II-leg-3 with 1 hair-like seta, II-leg-4 with 5 swimming setae, II-leg-5 with 3 swimming and 1 hair-like setae; III-leg-3 with 1 hair- like seta, III-leg-4 with 5 swimming setae and III-leg- 5 with 3 swimming and 2 hair-like setae; [V-leg-4 with 4 hair-like setae and IV-leg-5 with 5 swimming setae. Female: Body soft, 747 u in length and 553 u in width. Anterior coxae with apodemes, but it is not possible to determine how far they extend posteriorly due to the poor condition of the specimen. Epimeroglandularia 2 small. Two pairs of acetabular plates, lying close two each other; the anterior plates with two pairs of acetabula and two setae, the posteri- or plates with three pairs of acetabula (arranged one behind the other) and each plate with one seta. Dorsal lengths of palp segments: PI 17 u, PII 89 u, PIII 38 u, PIV 84 u and PV 60 u; PIV with two small tubercles, PV with three short setae on dorsal margin. Dorsal lengths of fourth leg: IV-leg-2 142 u, IV-leg-3 154 u, IV-leg-4 178 u, IV-leg-5 221 u and IV-leg-6 187 u. Legs 1-3 with large claws and 3 clawlets (2 large and one small), leg 4 with 4 clawlets. Similarly the female has long, hair-like setae and broad swim- ming setae. I-leg-3 with 1 hair-like seta, I-leg-4 with 5 swimming setae, I-leg-5 with 5 swimming and 1 hair- 100 like setae; II-leg-3 with 1 hair-like setae, II-leg-4 with 6 swimming setae, II-leg-5 with 5 swimming setae; III-leg-3 with 1 swimming and 1 hair-like seta, III- leg-4 with 5 swimming and 1 hair-like setae, III-leg-5 with 3 swimming and 1 hair-like setae; IV-leg-5 with 3 swimming and 1 hair-like setae, IV-leg-4 with 2 swimming and | hair-like setae. Etymology. — The species is named after Mr. Henk van der Hammen. Discussion. — The unique structure of the male palp separates this species from any other member of the genus. Other diagnostic characters for the male include the number of clawlets of the claws. The structure of the palp of the female is also diagnostic. Unionicola ( Unionicola) flabelliseta Cook, 1986 (fig. 35) Cook (1986) described only the male. Only fe- males were found in the present study and a descrip- tion is given below. Female: Body soft, 999 u in length and 805 u in width. Ventrally with a pair of raised glandularia tu- bercles at posterolateral corners of body. Fourth cox- ae with small posteromedial projections but with very long setae. Epimeroglandularia 2 small. Two pairs of acetabular plates, each plate with three acetabula. Dorsal lengths of palp segments: PI 17 u, PII 214 u, PHI 62 u, PIV 178 u, PV 82 u. The female, like the male, has an expanded fan-shaped peg-like setae on PIV. Dorsal lengths of distal segments of first leg: I- leg-4 262 u, I-leg-5 223 u, I-leg-6 194 u. Dorsal lengths of distal segments of fourth leg: IV-leg-4 252 u, IV-leg-5 369 u, IV-leg-6 349 u.

(figs. 36-37) Type material. — Holotype female: Cattle pond north of Bundjalung NP, New South Wales (loc. 6). Description Female: Body soft, 553 u in length and 398 u in width. A pair of raised glandularia tubercles at poste- rolateral corners of body. Tips of second and third coxae rounded. Five pairs of genital acetabula, these placed on two pairs of acetabular plates. Posterior pair of acetabular plates with three pairs of acetabula and one pair of heavy setae; anterior plates with two pairs of acetabula and two pairs of heavy setae. Lengths of palp segments: PI 14 u, PII 103 u, PIII 48 u, PIV 106 u, PV 55 u. Peg-like seta of PIV at extreme dis- toventral end not on a tubercle; one of the hair-like setae on PIV on a short tubercle. PII with a long lateral seta; PII with two short lateral setae. Dorsal lengths of first leg: I-leg-4 226 u, I-leg-5 218 u, I-leg- 6 151 u. Dorsal lengths of fourth leg: IV-leg-4 262 u, IV-leg-5 320 u, IV-leg-6 272 u. Male: Unknown. Etymology. — The species is named after Dr. C. Davids. Discussion. — This species is close to U. minutissi- ma Lundblad and U. alpa Cook. It differs from both species in the structure of the palp (PV of U. davidsi is relatively short and PIV has a different shape), the larger size and the very long leg segments. Unionicola (Pentatax) sp. Two Unionicola-females from location 19 have shorter palps and shorter leg segments than U. david- si. They resemble the latter species in most details, but may belong to a different species. For one of these female the dorsal lengths of the palp and leg segments are: PII 84 u, PIII 34 u, PIV 86 u, PV 53 u; I-leg-4 175 u, I-leg-5 168 u, I-leg-6 125 u; IV-leg-4 194 u, IV-leg-5 261 u, IV-leg-6 240 u.

Neumania (Neumania) nodosa (Daday, 1898) N. nodosa is a widespread species, reported from India, Indonesia, Japan and also from the Northern Smit: Water mites from Australia Territory, Australia (Viets 1981). Measurements and number of acetabula are vari- able. The Australian specimens are larger than the specimens taken by Cook (1967) in India. Australian females measured 960-1248 u, females from India 653-714 u. Females from Indonesia are intermediate i.e. 800-1000 u (Piersig 1906). There are also differ- ences in the lengths of the leg and palp segments.

Description Male: Dorsal shield fused with ventral shield poste- riorly thus making the dorsal furrow incomplete. Dorsal shield 446 u in length and 393 u in width and with 4 pairs of glandularia, the three most posterior pairs on tubercles. Tips of first coxae rounded and projecting beyond the body proper. Genital field with 15-20 acetabula. Dorsal lengths of palp segments: PI 24 u, PIT 96 u, PIII 46 u, PIV 84 u, PV 26 u. Dorsal heavy terminal seta of PV diverging from the others; ventral side of PII straight, PII stocky. Dorsal lengths of fourth leg: IV-leg-2 107 u, IV-leg-3 116 u, IV-leg- 4 145 u, IV-leg-5 242 u, IV-leg-6 184 u. IV-leg-5 bowed, the three unmodified specialized setae in the proximal half of segment. Proximal two of these setae closer to each other than the two distally sited setae. The distal end of this segment with a prominently pectinate seta. [V-leg-4 and IV-leg-5 with 3 swim- ming setae; IV-leg-4 with 2 large pectinate setae and 1 small pectinate seta, IV-leg-3 with 1 pectinate seta. Female: Dorsal and ventral shield present; dorsal shield 611 u in length and 495 u in width. Dorsal shield with three pairs of glandularia on small tuber- cles, a fourth pair of glandularia lying free in the dor- sal furrow on large tubercles. Tubercles on ventral shield large, especially on lateral side of body. Posterior apodemes of anterior coxal groups extend- ing to middle of third coxae. Acetabular plates with numerous acetabula. Dorsal lengths of palp segments: PI 24 u, PIT 96 u, PIII 46, PIV 89 u, PV 29 u; palp as illustrated for the male. Dorsal lengths of distal three segments of first and fourth leg: I-leg-4 136 u, I-leg-5 155 u, I-leg-6 155 u; IV-leg-4 155 u, IV-leg- 5 208 u, IV-leg-6 194 u; Ill-and IV-leg-5, III- and IV-leg-4 with three swimming setae, III- and IV-leg- 3 with two swimming setae. Etymology. — The species is named for its large, pectinate setae. Discussion. — The fourth leg of the male of this species resembles that of À. baltoona and R. tinka; it differs from the first species in the absence of a bulge on IV-leg-4 and the heavy pectinate seta on the distal end. À. tinka has the three setae of IV-leg-4 close to each other and on a small but clear bulge. Males and females of R. tinka and R.pectinatus have a stocky sec- ond palp segment; females of the two species differ in the form of acetabular plates and tubercles.

Koenikea ( Notomideopsis) verrucosa Lundblad, 1948 Lundblad (1948) described the species from a new- ly metamorphosed male from Tasmania. This male differed from K. australica in having much larger glandularia tubercles. Cook (1986) suggested that older specimens have smaller tubercles, and therefore questioned the validity of K. verrucosa. At one loca- tion in this study males and females were found with large glandularia tubercles and these were compared with males and females with small tubercles assigned to K. australica. It is clear that K. verrucosa should stand as a distinct species. The glandularia tubercles of K. verrucosa measure 24-29 U and those of K. aus- tralica 12-16 U. Further, K. verrucosa has more and larger papillae on the body than X. australica. The fe- male of K. verrucosa is briefly characterized below. Female: Body 630 u in length and 601 u in width; dorsal shield 563 u in length and 495 u in width. Dorsal shield with five pairs of large glandularia tu- bercles. Body with large papillae.

Koenikea (Notomideopsis) voloma Cook, 1986 (figs. 46-47) Previously reported from Tasmania and New South Wales. Cook (1986) provided a good description of this species. Only females were found in the present study, which, although not entirely fitting the de- scription of K. voloma by Cook (1986), have all been assigned to that species. A short description of these specimens is given below (the measurements given by Cook for the allotype and paratype are shown in pa- rentheses). Female: Dorsal shield 650-718 u ( 684-729) in length and 504-548 u (562-638) in width. Dorsal 104 shield with 6 pairs of glandularia; glandularia 3, 4 and 5 more or less in a line. Tips of first coxae rounded and not projecting to anterior end of body. Epimeroglandularia 2 located near posterior suture lines of fourth coxae. Genital field close to posterior of body. Gonopore 116-126 u (120-122) in width; acetabular region 281-310 u (318-347) in width. Dorsal lengths of palp segments: PI 26 u (26-27), PII 77-84 u (85-86), PIII 48-53 u (48-51), PIV 77-84 u (88-90), PV 38 u (40-43); peg-like seta of PIV on a short tubercle. The location of this seta varies (even within a specimen), from near the distal end of this segment to somewhat more proximal. First leg with long ‘rillborsten’ (fluted or grooved setae). Discussion. — The females of this study have a more elliptical dorsal shield compared with the origi- nal description presented by Cook (1986). The loca- tion of the peg-like seta of PIV varies, so this charac- ter does not separate this species from other species, e.g. K. jacunda. Material examined. — Queensland: 5 ®, loc. 18; 1 9, loc.40.

Epimeroglandularia 2 lying in an indentation of the posterior margin of the fourth coxae. Acetabular plates broad, 116 U in length with one pair of glan- dularia and 10-15 small acetabula. Gonopore 87 U in length. Excretory pore terminal. Dorsal lengths of palp segments: PI 22 u, PII 70 u, PIII 48 u, PIV 70 u, PV 36 u; peg-like seta of PIV not inserted on a tu- bercle. Dorsal lengths of last three segments of fourth leg: IV-leg-4 126 u, IV-leg-5 155 u and IV-leg-6 184 u. One swimming seta on II-leg-4, two on I-leg-5, II- leg-5, III-leg-4, IIl-leg-5, and three on IV-leg-4 and IV-leg-5. First two legs with ‘rillborsten’. Female: Body purple, 718 u in length and 679 u in width. Dorsal furrow complete; dorsal shield 708 u in length and 621 u in width. Tips of first coxae not ex- tending to anterior end of body. Posterior apodemes of anterior coxal groups extending posteriorly beyond suture lines between third and fourth coxae. Second coxae each with one very long, stiff seta. Acetabular fields with one pair of glandularia and 10-15 small acetabula. Gonopore 107 u in length. Dorsal length of palp segments: PI 21 u, PII 74 u, PIII 48 u, PIV 72 u, PV 43 u; setae on PIII larger than in male, PV relatively more slender; peg-like seta on PIV not on a tubercle. First two legs with ‘rillborsten’. Dorsal lengths of last three segments of fourth leg: [V-leg-4 136 u, IV-leg-5 155 u and IV-leg-6 165 u. One swimming seta on Il-leg-3 and IV-leg-4, two swim- ming seta on I-leg-5, three swimming setae on I]-leg- 5, Hl-leg-5, IV-leg-4 and IV-leg-5; legs 3 and 4 with rather large setae. Etymology. — The species is named for its conspic- uous colour. Discussion. — The colour of the body (purple, even after preservation in Koenike's solution) and the very long stiff seta on the second coxa are diagnostic for this species. Smit: Water mites from Australia Albia Thon Albia (Albiella) brokenensis sp. n. (figs.52-54) Type material. — Holotype female: Broken River, Eungella NP, Queensland (loc. 18). Description Female: Dorsal and ventral shields present. Body 1047 u in length and 737 u in width. Dorsal shield with 5 pairs of glandularia, one pair of glandularia lying in the dorsal furrow. Dorsoglandularia 3 and 4 lying very close to each other, dorsoglandularia 4 mo- re medial. Glandularia of the fourth coxae extending forward causing a slight bowing of the suture lines between third and fourth coxae. None of the coxal setae thickened.

Dorsal lengths of palp segments: PI 35 u, PII 120 u, PIII 72 u, PIV 139 u, PV 53 u. Dorsal lengths of last three segments of first leg: I-leg-4 110 u, I-leg-5 125 u, I-leg-6 132 u. Fifth segment of second, third and fourth legs with numerous swimming setae; claws of legs with one clawlet. Male: Unknown. Etymology. — The species is named after the type locality. Discussion. — This species is very close to A. austra- lica Cook. It differs in the position of dorsoglandular- ia 3 and 4, and in the form of the acetabular plates. The anterior margin of the body of A. brokenensis is almost straight, whilst that of A. australica is rounded.

The species is also men- tioned by Viets (1975), without giving the precise lo- 106 cation (but possibly Queensland). The male was hitherto unknown. At one location both females and males were collected. The male characters indicate that the species belong to the subgenus Megaluracarus. A description is given below. Male: Body 1536 u in length , 1248 u in width and 1416 u in height. Dorsum with three large, well separated humps (as in the female) and four smaller humps in anterior portion of dorsum. Eyes located on the most lateral, rather pointed humps; the more me- dial pair of these humps less pointed. Dorsal furrow complete. Ventral side with a small epimeral field. Acetabular plates extending to lateral margins of body, the posterior margin slightly undulating. Gonopore small, 68 jt in length.

Pycnogonida from southern Brazil. — Tijdschrift voor Entomologie, 135: 113-139, figs. 1-80. [issn 0040-7496]. Published 15 July 1992. Records of Pycnogonida collected at 85 different stations in southern Brazil, between 18°34' S and 34°27' S. Four of these were sampled by hand or by skin-diving in the littoral and upper infralittoral zones, six stations were located on the continental slope between 250 and 1100 m, the remaining 75 were on the continental shelf. Forty-four species are represented, dispersed over 16 genera in seven families. Seven species are new to science, in the genera Eurycyde (E. platyspina sp. n.), Achelia (A. columnaris sp. n.), Nymphon (N. bullatum, N. inaequipes, N. vul- canellum spp. n.), Anoplodactylus (A. spurius sp. n.), and Pycnogonum (P. ornans sp. n.). New to the fauna of Brazil are eight species. New synonymies are proposed in Pallenopsis (P. boehmi Schimkewitsch, 1930 = P. longicoxa Stock, 1966) and Anoplodactylus (A. petiolatus (Kroyer, 1844) = A. guyanensis Child, 1977). J.H. Stock, Institute of Taxonomic Zoology, P. O. Box 4766, 1009 AT Amsterdam, The Netherlands. Key words. — Pycnogonida, taxonomy, distribution, Brazil, littoral, shelf, continental slope. The pycnogonid fauna of southern Brazil is rela- tively well-studied, mainly through the monographic treatment of Marcus (1940b) and a number of satel- lite papers in the following decades by Corrêa (1948), Sawaya (1945, 1947, 1950, 1951), Zilberberg (1963), Zago (1970), de Mello-Leitao (1945, 1946, 1949 a, b, 1955), Marcus & Marcus (1963) and Marcus-du Bois-Reymond (1952). Occasionally, large expeditions collected material on the Brazilian coast, e.g. the ‘Challenger’ (Hoek 1881), the ‘Vettor Pisani’ (Schimkewitsch 1890), the ‘Calypso’ (Stock 1966), and some American cruises (Child 1982a). Nevertheless the present collections from southern Brazil form a fine addition to our previous know- ledge. The material was brought together by the late Dr. Plinio Soares Moreira of the Instituto Oceanographico of the University of Sao Paulo (usp), mainly on board of the Oceanographic Research Vessel ‘Prof. W. Besnard’. The amount of previous work done explains why the number of new species in the present collection is relatively low (7 out of 44, or 16%). However, taken into consideration that another eight species are new to Brazil, a total of 15 species is added to the Brazilian fauna, which is not too bad a score (more than one- third of the species represented in this collection). Biogeographically, endemics and warm-water spe- cies are predominant in the Brazilian fauna, not sur- prising in the light of the South Atlantic Drift which distributes tropical waters along major parts of the coastline of the country. As table 1 shows, a good number of species (viz. 21) is endemic to Brazil (and neighbouring territo- ries, the Mar del Plata and the Guyanas). Another group of eleven species are mainly warm-water ele- ments which have their distribution centre in the Caribbean. One of these species, Ammothella spinife- ra, occurs on the Pacific coasts of the Americas as well. Interesting is a small group of seven species oc- curring on both sides of the Atlantic Ocean (so-called amphi-Atlantic species). Finally, some Magellanean cold-water species reach their northern distribution limits on the shelf of southern Brazil, but this group contains only three species in all. METHODS Entire specimens were studied and measured in glycerin or lactophenol, dissected appendages on per- manent slides in Reyne's modification of Faure's me- dium. All specimens have been deposited in the Zoölogisch Museum, Amsterdam (ZMA). DESCRIPTIVE PART Family Ammotheidae Eurycyde platyspina sp. n.

Scales after fig. 80. 114 genus, the two sexes are very similar in spination, etc., even in the morphology of the oviger. Secondary sex- ual differences (presence of femoral cement gland tube in male, large genital pores on ventral surface of coxa 2 of all legs in female) may serve to discriminate between the sexes. Trunk completely segmented; mid-dorsal line without tubercles. Lateral processes separated by nar- row intervals, distally with low tubercle. Oviger im- plantation free of first lateral process. Proboscis with articulated stalk, distal part directed downward. Abdomen straight in basal part; at about 80% of its length 6 setae are implanted at bend of abdomen. Ocular tubercle cylindrical with pointed tip; eyes small, well-pigmented, touching; no setae on ocular tubercle. Chelifore scape 2-segmented, segments subequal in length; segm. 1 with 3 long spines, segm. 2 with 7. Chela not retracted in distal end of scape; hand glob- ular, with 1 rudimentary finger and 2 setae. All spines (on chelifores, coxae 1 and 2, femur and tibiae 1 and 2) are of rather peculiar morphology (fig. 1, detail), viz. flattened, with more or less obtuse tip and with distal spinule, both margins with some lat- eral setules. Palp segm. 1 with very strong lateral spur; segm. 2 minute; segm. 3 longest; segm. 6 shorter than 7; segms. 7 to 9 subequal, segm. 10 shorter. Oviger segm. 4 longest; segms. 7 to 10 with 2 rows of compound spines, in longest row according to for- mula 6:4:4:5. Compound spines with 3 small proxi- mal marginal teeth, then 1 large tooth, and 4 to 5 smaller distal teeth. Terminal claw short, slightly curved, smooth. Coxa 1 with 2 long disto-dorsal spurs and 2 more proximal dorsal spines. Coxa 2 with 2 + 2 dorsal spines. Coxa 3 with minute spinules only. Femur of male with swelling at about 40% of posterior surface, bearing tube of cement gland; femur of female with- out such swelling; distal end of femur with 4 long spines. Tibiae 1 and 2 with several (5-7) long dorsal spines, plus some long lateral spines. Tarsus short. Propodus slightly curved, distally widening, no heel; sole with 12-14 spinules of uniform size. Claw short, curved; no auxiliary claws. Female genital pores on distoventral surface of coxa 2 of all legs; male cement glands on femur of all legs. Measurements (mm) of holotype: Length trunk (frontal margin cephalic segment to tip 4th lateral process) 1.71; diameter across 2nd lateral processes 1.17; length abdomen 0.58; length proboscis 1.36.

Etymology. - The specific name, platyspina, refers to the curious shape of the spines on chelifores, abdo- Jan H. Stock: Brazilian Pycnogonida men and legs. Remarks. — Child (1988b) has presented a key to the species of Eurycyde. Since the construction of this key, three more species became known: E. antarctica Child, 1987 (which can be traced down to couplet 7 of the key), E. longioculata Müller, 1990 and E. dia- cantha Stock, 1990 (both ‘strand’ in couplet 3 of the key). Child (1988b: 7) remarks that £. acanthopus Stock, 1979 (described from a female) is probably the opposite sex of E. curvata Child, 1979 (described from a male). If this supposition is true, it might be useful to know which name has priority. It turned out to be almost a photofinish: E. acanthopus was pub- lished Sep 10, 1979, and E. curvata Sep 27, 1979, so the former name has priority. Eurycyde platyspina sp. n. can be followed in Child's key to couplet 7, along with the couple acan- thopus | curvata, hispida (Kroyer, 1844) and antarcti- ca. It differs from antarctica in having long spines on the abdomen (abdomen practically glabrous in ant- arctica), and from acanthopus/curvata in having the abdominal spines arranged in a single dorsal group (versus scattered over the abdomen). Finally it differs from hispida in the presence of a tubercle on the later- al processes and 2 spurs on coxa 1 (none in hispida). Nymphopsis melidae Sawaya, 1947 N. melidae Sawaya, 1947: 83-87, pls.

Remarks. - Up to now this species has been record- ed only once: Sawaya (1947) described a single male from the upper littoral zone of Ilha das Palmas, Baia de Santos (ca. 24° S). The present records are more north, and from deeper shelf waters (15-41 m). The juveniles in this collection have an unsegment- ed scape, the adults a 2-segmented scape. This fea- ture, often used as a key character, should be used with some care. Cilunculus sp. Material. - 1 juvenile, Project Isotan-Draga I, Stn MBT 143: 24°08'S 42°28'W, 1020 m, 2 Sep 1970. Remarks. - This juvenile has still retained its che- lae, and the ovigers are an undeveloped, sausage-like structure. In most of its characters, it resembles close- ly €. europaeus Stock, 1978, from deep waters of the Bay of Biscay and the entrance of the English Channel (absence of an ocular tubercle, long setae on the legs, long auxiliary claws, absence of mid-dorsal 115 TIJDSCHRIFT VOOR ENTOMOLOGIE, VOLUME 135, 1992 trunk tubercles), but it differs from C. europaeus in the naked lateral processes (setose in europaeus) and in the greater space between the anterior lateral process- es (interval 3 times the diameter of the lateral pro- cess). The propodal heel bears 1 larger spine (2 in eu- ropaeus) and the sole bears only 6 spines, which are longer than those of europaeus. I presume this specimen represents an undescribed species, but in absence of adults I refrain from nam- ing it. The genus Cilunculus is new to Brazil.

Remarks. - The female of Stn. MBT 165 is in agree- ment with the general diagnosis of this species. The male of Stn. F 23 is intermediate between A. appendi- culata and A. rugulosa (vide infra), in that it has the short first scape segment of the former, but it possess- es a hollow spine on the scape and spines on the later- al processes, that characterize the latter. Presumably the two species are identical. A. appendiculata is an amphi-Atlantic species, al- ready known from Brazil (Marcus 1940b).

Remarks. — The adult male agrees well with the characteristics presumed to characterize this species. However, in view of the large range of variation ob- served in A. appendiculata (vide supra), and in agree- ment with the opinion of Stock (1975a) and Child (1979), A. rugulosa is probably synonymous with that species. A. rugulosa is a West Indian species, recorded be- fore from Brazil by Marcus (1940b).

The species is mainly known from the Pacific (from southern California to the coast of Panamá and the Galapagos Islands). Child (1979) was the first to record it from the Caribbean coast of Panamá, and re- cently Müller (1990b) recorded it from Martinique and Barbados. Its range is considerably extended southward, to the coast of southern Brazil, by the present record. Achelia besnardi Sawaya, 1951 A. besnardi; Stock 1975b: 70-71, figs. 1-9 [older refs.]. Material. - 1 d, Project Petrobas/usp, Stn. RD 40: 19°15.8'S 38°56.3'W, 59 m, 11 July 1972. Remarks. — This specimen resembles closely Sawaya's (1951) good illustrations. It is a relatively rare species, having been found off Rio de Janeiro, in the Virgin Islands, and the Bahamas. There is no ma- terial available that substantiates Fry & Hedgpeth's claim (1969: 102) that the species occurs in the for- mer Belgian Congo or (on their distribution map, fig. 155) on the South American coast as far south as 45°. Probably, these authors have confused A. besnardi with A. sawayai (vide infra) which was recorded by Fage (1949) from Zaire. Contrary to Fry & Hedgpeth's (1969: 105) opin- ion, I consider this species closely related to A. saway- ai, with which it agrees in two essential characters: (1) all spines on the propodal sole are of equal size, and (2) absence of a male genital spur.

Tarsus short, with 4 or 5 ventral spines. Propodus slightly curved, heel with 3 or 4 large spines; sole with some 7 smaller spines. Auxiliary claws more than half as long as main claw. Genital spur long, thump-shaped, on ventrodistal corner of coxa 2 of legs 3 and 4. Female: Mid-dorsal trunk tubercles simple (not bi- fid); tubercle over base of abdomen lacking.

Etymology. - The proposed specific name, colum- naris (Latin, pillar-shaped) alludes to the shape of the spurs on femur and tibiae. Remarks. — The new species shows, by the presence of a row of mid-dorsal trunk tubercles, a strong simi- larity to the Achelia assimilis/wilsoni/variabilis com- 118 plex (see Hedgpeth 1961), frequently recorded from the major oceans of the southern hemisphere. However, none of the recorded ‘variations’ has tall, pillar-shaped spurs on femur and tibiae. Similar tall spurs are present on palp segments 2 and 3 of the new species, whereas in the A. assimilis group just a tuber- cle is present. The very strong armature of the legs is not unlike that found in À. setulosa (Loman, 1912), but that spe- cies lacks mid-dorsal trunk and palp spurs, and has a less slender distal palp segment. Other very spinose Achelia species from the central Atlantic Ocean are A. turba Stock, 1990 (which has however no mid-dorsal trunk spurs, shorter spurs on the long leg segments, a shorter male genital spur, and a less pointed proboscis), and A. armata (Bouvier, 1916) (which lacks spurs on the long leg segments or in the mid-dorsal line and has less elongate femur, tibiae 1 and 2, and propodus).

It resembles the female in almost every charac- ter, except for the tuberculation of coxa 1, which is slightly stronger in the male, and of course the struc- ture of the oviger. The male oviger has an ecto-distal apophysis on segment 7, which places 7° acuminatum in a group of species comprising 7. tubirostrum Stock, 1954, 7. dowi Child, 1979, 7. oculospinosum Hilton, 1942, T. isthmiacum Stock, 1955, and 7. isabellae Marcus, 1940.

Remarks. - The single specimen is badly damaged, but is probably this species. 7° evelinae was already found in the same general area by Marcus (1940b), but was never recorded again. As point of fact it re- sembles strongly 7. haswelli Child, 1990, an Australian form. The palps of haswelli are 4-segment- ed, those of the types of evelinae 6-segmented, but in the present specimen, articulation lines in the basal part of the palp are obscure, resulting in a 4-segment- ed appearance of the appendage.

The pe- nultimate palp segment is slightly less lobate than Marcus’ figure 14E suggests, but it is in good agree- ment with Fage's fig. 5. This species is strikingly similar to 7° oculospino- sum Hilton, 1942 (vide Child & Hedgpeth 1971: 619, fig. 5, and Child 1979: 34), a Pacific species ranging from Baja California to the Galapagos Islands. The only difference seems to be the second tibia which looks shorter in Child & Hedgpeth's fig. 5c. I suppose, however, that both species are synony- mous, in which case Marcus’ name has priority. Child (1979) records another Tanystylum, T. tubirostrum Stock, 1954 and several other species of Pycnogonida from both the Atlantic and the Pacific side of the Americas, so from a biogeographic point of view it would not be too surprising if the Pacific 7. oculospi- nosum and the Atlantic 7: isabellae were synonymous.

Remarks. — The proboscis shape resembles Marcus (1940b) figure rather than Krapp's (1973) illustra- tion. The female oviger is 10-segmented (versus 9- segmented in the closely similar 7. conirostre) and the propodal armature is as Krapp describes for 7. orbic- ulare. The abdomen too, resembles Marcus fig. 15A, instead of Child's (1990) fig. 3 A-B. Perhaps this is not orbiculare at all, but another look-alike in this dif ficult genus. Family Nymphonidae Jan H.

Etymology. - The specific name is derived from bulla (Latin = knob, bump) and alludes to the apoph- ysis on oviger segment 5 in the male. Remarks. - Two outstanding features of the male differentiate this species from the 200-odd others in the genus: (1) the cement glands discharging through volcano-shaped prominences; and above all (2) the apophysis on oviger segment 5 which is not apical (as in many other Nymphon species) but localized at two- thirds of the segment. Cement gland apertures similar to those of the new species, are known from two other species only: N. discorsicoxae Child, 1982 and N. caldarium Stock, 1988. The former, however, is a brevitarsal species (whereas N. bullatum is longitarsal) and the latter is uniunguiculate (whereas N. bullatum possesses auxil- iary claws). Morphologically closest to N. bullatum are perhaps N. sandersi Child, 1982 (from off Rio de la Plata, Argentina, 3815-4435 m) and N. longicollum Hoek, 1881 (off Valparaiso, Chile, 2225 fms = 4072 m). Since some of the most useful diagnostic characters in the genus Nymphon are sex-linked (male oviger and male cement glands), it is hard to judge about the re- lationships of these two species, of which the (adult) male is unknown. Both differ from N. bullatum in that the auxiliary claws are tiny or lacking, and the oc- ular tubercle is slender and conical, without eyes. Some additional differences berween N. sandersi and N. bullatum are: (1) palp segm. 2 = 3 in sandersi, 2 > 3 in bullatum; (2) oviger claw with 3 teeth in sander- si, 6-7 in bullatum; (3) compound oviger spines with 5 pairs of teeth in sandersi, 2-3 in bullatum. In N. lon- gicollum (vide Gordon 1932a) the chela is straighter and the palm is longer than in N. bullatum, and each finger bears 11-12 teeth only (14-19 in bullatum). 123 TIJDSCHRIFT VOOR ENTOMOLOGIE, VOLUME 135, 1992 Nymphon inaequipes sp. n.

Lateral processes long, slender, separated by intervals more than twice as wide as diameter of each lateral process. Neck widened at anterior end, fol- lowed by long, narrow, parallel-sided part. Oviger implantation in contact with anterior margin of first lateral process; on dorsal side of neck, right and left implantations fused (looking like segmentation line, but such line absent on ventral surface of neck). Ocular tubercle mainly cylindrical, rather low; rounded point at distal end; eyes small, well-pigment- ed. Abdomen short (in dorsal view not extending be- yond 4th lateral processes), directed obliquely up- ward and backward (angle with horizontal ca. 75°). Proboscis swollen at basal third, and again at distal third, shorter than neck. Chelifore scapes strongly diverging, practically un- armed. Chela much longer than scape. Fingers longer than palm, curved near tip. Each finger with numer- ous (ca. 55) unequal teeth: a larger tooth is alternating with 2 to 4 smaller teeth (some of the smaller teeth bi- fid); larger teeth of movable finger shorter and more obtuse, on immovable finger larger and pointed. In juveniles, number of teeth on fingers lower. Palp segms. 2 to 5 very slender, in proportions 9:7:8:6. Long setae in particular on segms. 4 and 5. Oviger of male: Segm. 5 almost straight, by far longer than segm. 4, with row of recurved spinules on ventral margin and with small distal apophysis. Segm. 6 curved, about one-third of length of segm. 5, with inconspicuous tubercle on dorsal margin. Compound spines, according to formula 8:6:6:6, with 3 large ba- sal teeth and 3 much smaller distal teeth on either margin. Distal claw long, slender, with 7 teeth. 124 Oviger of female: Much weaker than that of male, segm. 5 not so much longer than segm. 4, straight, without recurved spinules. Segm. 6 straight. Spine formula 10:7:6:8::10. Legs long and thin. Coxae almost naked; coxa 2 of leg 1 less elongate than that of P2-P4. Femur < tibia 1; tibia 2 slightly longer than tibia 1. Several rather short setae, in particular on tibiae. Leg 1 having distal segms. different from those of other legs (heteropo- dy); in leg 1 tarsus > propodus, both densely set with small spinules of uniform size on ventral surface;7 claw of leg 1 short (ca. 25% of length of propodus); auxiliary claws almost 90% of length of main claw. In remaining legs, tarsus < propodus, sparsely armed with small spinules; claw long (about 50% of length of propodus); auxiliary claws about 80% of length of main claw. Heteropody already visible in juveniles. Femur of female strongly swollen in basal half, for conception of eggs. Femoral gland pores in male in- conspicuous; a bulbous, subcutaneous vesicle opens through a longish, narrow, subcutaneous duct into a minute pore; 8 or 9 glands present on each leg. Sexual openings of female on distoventral end of coxa 2 of all legs. Measurements (mm) of female from Stn.

Etymology. — The specific name, inaequipes (Latin, with unequal legs) alludes to the morphological dif- ferences between leg 1 and the remaining legs. Distribution. — This is a rather common, some- times even abundant species in our samples. It has been found in depths between 26 and 500 m. Remarks. - The present species is rather similar to the next, N. vulcanellum. Look-alikes must be sought amongst such taxa as N. macrum Wilson, 1880, N. gracillimum Calman, 1915, and N. hiemale Hodgson, 1907. N. inaequipes differs from these as follows: — From N. vulcanellum by the cement gland aper- tures which are flush with the femoral surface (not raised), the fingers of the chela which bears >50 teeth of unequal size (versus <26 teeth of uniform size), the longer auxiliary claws, and the heteropodous nature of the legs. In mixed collections of N. vulcanellum and N. inaequipes, which are common, the latter can be distinguished at first glance by its smaller size, JAN H. Stock: Brazilian Pycnogonida Figs. 42-46.

In none of these species heteropody is recorded. In fact, this is a rather rare phenomenon, more usually found in unrelated genera, such as Ascorhynchus. Nymphon vulcanellum sp. n.

Description. - Trunk completely segmented, prac- tically unarmed. Lateral processes > diameter trunk, intervals slightly larger than diameter of lateral pro- cess. Anterior part of neck strongly widened; short parallel-sided basal part. Ocular tubercle truncate, with 2 minute lateral, and 1 terminal tubercle; eyes 126 present. Oviger implantation in contact with anterior margin of first lateral process. Abdomen long, reach- ing beyond middle of coxa 1 of leg 4, almost horizon- tal. Proboscis barrel-shaped, short. Chelifore scapes strongly divergent, poorly armed. Chela longer than scape. Fingers not in same plane as palm, longer than palm. Movable finger curved at tip, immovable finger regularly curved; each finger with 20-25 teeth, those of immovable finger longer than those of movable finger. Palp segm. 2 > 3 > 4 > 5; segms. 3 and 4 unusually slender. Oviger of male: Segm. 5 >> 4, somewhat S-shaped, distally swollen. Segm. 6 most remarkable, because showing a subdivision into 2 segments (segmentation more or less distinct, sometimes looking functional, see arrow in fig. 58). Compound spines with 3, rarely 4, marginal teeth; formula 12:8:6:6. Claw with 6 teeth. Oviger of female: Segm. 5 straight, slightly longer than 4; segm. 6 not subdivided. Spine formula 5:6:6: 72:5). Legs: Femur of female slightly swollen in proximal part. Femur of male with some 16 cement gland aper- tures on ventral margin of all legs. Apertures shaped like low, truncate volcanoes. Coxa 2 and both tibiae with some long setae. Femur < tibia 1; tibia 1 slightly longer than tibia 2. Tarsus slightly longer than propo- dus; ventral margin of tarsus and propodus densely packed with minute spinules of uniform size (no heel, no heel spines). Claw short; auxiliary claws about half length of main claw. Legs homoiopodous. Measurements of 9 from Stn. MBT 142 (mm). — Length proboscis (dorsal) 1.24; greatest diameter pro- boscis 0.64; length first trunk segm. 1.59; length sec- ond trunk segm. 0.87; length third trunk segment 0.82; length fourth trunk segment (to tip fourth lat- eral process) 1.05; width across second lateral process- es 2.15; length abdomen 0.91. Leg 3: first coxa 0.90; second coxa 1.64; third coxa 0.63; femur 3.78; first tibia 5.29; second tibia 5.12; tarsus 1.40; propodus 1.11; claw 0.40; auxiliary claws 0.20. Etymology. — The specific name, vulcanellum (Latin = little volcano) alludes to the low, volcano- shaped cement gland apertures on the femur of the male. Remarks. - This is no doubt the same species re- corded as “Nymphon spec.’ by Stock (1966), from one of the ‘Calypso’ stations off the South American Atlantic coast. In 1966, though it was recognized that probably a new species was concerned, it was not named because only a female was available. Now, the male being discovered, I have no hesitation any more to attribute this highly characteristic animal to a new species. Jan H. Srock: Brazilian Pycnogonida 55: 53 & Figs. 52-56.

Scales after fig. 80. 127 TIJDSCHRIFT VOOR ENTOMOLOGIE, VOLUME 135, 1992 By the large chela, the absence of propodal heel spines, and the slender palp segments, the new species looks like the North Atlantic N. macrum Wilson, 1880. Obvious differences are, apart from the volca- no-shaped cement gland apertures, the ratio tibia 1/tibia 2 (subequal in the new species, tibia 2 by far the longest in N. macrum), the low number of denti- cles on the oviger claw, and the low number of margi- nal teeth on the compound oviger spines of the new species. Finally, the oviger implantation is in contact with the first lateral process in the new species, im- planted well in front of it in N. macrum. For the differences from N. inaequipes, consult the remarks under the latter. Distribution. - Found often together with N. inae- quipes (vide supra), but is less abundant. Its bathy- metrical range lies between 21 and 250 m. Family Callipallenidae Callipallene evelinae Marcus, 1940 C. evelinae Marcus, 1940b: 31-33, fig. 2 A-D. Material. — 1 juv., usp, Stn.

Remarks. - C. evelinae is mainly characterized by male characters (presence of plumose setae on distal leg segments, absence of lobe on 5th oviger segment). Thus, the identification of the present material (lack- ing males) must be taken with some reservation. However, nothing in the morphology seems to pre- vent identification with C. evelinae, previously known only from Ilha das Palmas, Bahia de Santos, 0-5 m. The present records extend the range to east of Rio de Janeiro, and to a depth of 130 m. Callipallene gabriellae Corrêa, 1948 C. gabriellae Corrêa, 1948: 1-4, figs. 1-6. Material. - 76 spms. (incl. ovigerous males and juve- niles), usp, Stn. P.E.: Collected by hand by divers in the in- fralittoral zone on seaweeds growing on rock, Ponta do Espia, Ubatuba, State of Säo Paulo, 20 Sep 1964. Remarks. - This species is extremely close to C. emaciata (Dohrn, 1881), known from the Mediterranean and from New England to the West Indies. Child (1979: 41) examined specimens from the entire range of C. emaciata and made some obser- vations on its morphology. In the configuration of the propodal spines and the auxiliary claws, the present material agrees with Child's observations. 128 Evidently, the shape of the trunk, oviger spines, pro- portions of the leg segments, curvature of the propo- dus, and length of the auxiliary claws, C. gabriellae and C. emaciata are practically identical. Corrêa used the presence or absence of a suture between trunk seg- ments 3 and 4 as a key character to separate the two species, but in the large sample from Brazil at hand, this feature proved to be too variable to be reliable. The only characters that made me decide to retain C. gabriellae as a distinct species, are its more swollen male(!) femur and the number of teeth on the fingers of the chela. Child (1979, in key) records about 15 teeth on each finger of C. emaciata, whereas in the present material of C. gabriellae there are 6-9 teeth. The number of propodal heel spines, considered to be diagnostic character by Child, varies between 4 and 5 in C. gabriellae. C. gabriellae has been described from the upper lit- toral zone of Ilha das Palmas, Bahia de Santos (Brazil). As far as I know, no further specimens have ever been recorded.

Remarks. - The formula of the compound oviger spines in the present male is 8:6:8:8, which is lower than the number recorded by Gordon (1932b), but about similar to that found by Hedgpeth (1961). The species is known from South Georgia, N. of the Falkland Islands, 120-320 m (Gordon 1932b); southern Chile, 70 m (Hedgpeth 1961), and from the Argentine slope, between 36°53'S and 38°13'S, 454- 2323 m (Child 1982a). The present record extends the range of the species further north to 23°41'S, but falls within the bathymetrical range. Callipallene producta (Sars, 1888) C. producta; Stock 1990: 227 [refs.].

Some of the present samples contain both sex- es, and prove boehmi to be a senior synonym of longi- coxa, as already suspected by Stock (1973). The length of the auxiliary claws is variable in these sam- ples: in some specimens they are some 40% of the length of the main claw, in others they are fully half as long. P. boehmi is predominantly a cold-water species, distributed from Magellan Strait to southern Brazil. One of the above stations, Stn. 1477, is located very close to the type-locality of P. longicoxa. 129 TIJDSCHRIFT VOOR ENTOMOLOGIE, VOLUME 135, 1992 Pallenopsis (Pallenopsis) candidoi de Mello-Leitäo, 1949 P.

Remarks. — I agree with Lebour (1945) and Hedgpeth (1948) in considering this south Brazilian shallow water species different from A. pygmaeus, under which name it was recorded by Marcus (1940b). Hedgpeth coined the name A. brasiliensis for it, which is adopted here. The species differs from A. pygmaeus by the presence of small auxiliary claws, and the absence of a tubercle on the lateral processes (a single spinule is present, however). The propodal sole has a rather short lamina, preceded by 3 or 4 sole spines. Unfortunately, the present collection contains no males, so I can add nothing to Marcus’ descrip- tion.

After re-examination of many samples from various origins (North Sea, Bay of Biscay, Israel, the Guyanas), I came to the conclusion that A. petio- latus is a variable species and that the variation occurs in a geographically unordered way. North Sea speci- mens have the lowest number of spines on the propo- dal sole in front of the lamina (viz. 3 to 6), medium- sized tubercles on the lateral processes, and no tubercle on coxa 1. Guyana specimens have 4 to 8 spines on the propodal sole, very tall tubercles on the lateral processes, and sometimes a distinct tubercle on coxa 1. Finally Brazilian specimens have the highest number (4 to 10) of spines on the propodal sole, me- dium-sized tubercles on the lateral processes, and a vestigial tubercle on coxa 1. The Bay of Biscay specimens look very much like A. guyanensis Child, 1977, but the abdomen is slight- ly longer and less erect. Israel specimens look strong- ly like A. vemae Child, 1982, but oviger segment 2 is shorter. The length of the cement gland tube and the trunk segmentation can vary as well. In our Brazilian collection, the tube is usually rather short, and speci- mens with an unsegmented trunk are more common, but other specimens show a segmentation line between trunk segments 1 and 2, or between 1, 2 and 3. Comments on the variability of À. petiolatus are al- ready briefly provided in the papers by Stock (1966, 1975a). For these reasons, I consider A. petiolatus a variable species, and has united A. longicollis (Dohrn, 1881) from the Mediterranean and A. guyanensis Child, 1977 with A. petiolatus (Kroyer, 1844). A. petiolatus was recorded before from Brazil (Marcus, 1940b) and northern Argentina (Stock, 1966). Anoplodactylus spurius sp. n.

Description. - Trunk segments 1 and 2, and 2 and 3 well-articulated, intersegmental line between seg- ments 3 and 4 vestigial. One tall spur and 1 or 2 spi- nules on distodorsal end of each lateral process. Lateral processes separated by interval greater than own diameter. Ocular tubercle with 2 minute lateral tubercles, tip conical; eyes pigmented. Abdomen more or less strongly directed upward, as long as 4th lateral process. 152 Proboscis of adult female with 2 ventral alar pro- cesses, free part of each lobe pointing forward. In ven- tral view, lobes are heart-shaped. Male proboscis without alar processes. Proboscis (4, ) surrounded by collar-like expansion with on either side a rounded swelling which might represent a rudiment of palp. Chelifore scape just overreaching tip of proboscis, with low distal spur. Chela with slender palm; curved fingers slightly longer than palm. Both palm and ectal margin of movable finger with several long setae. Each finger with 2 proximal setae on endal margin. Oviger 6-segmented; segm. 2 slightly less than half as long as segm. 3; segm. 3 very elongate; segms. 5 and 6 with several long setae; segm. 6 longer than wide, pointed. Legs setose, especially femur and tibiae. Tubercles and spurs variously developed (strongest develop- ment in one of the females!). Coxa 1 with 2 to 10 tu- bercles, most tubercles spine-tipped. Coxa 2 with ventrodistal genital spur only (male spur thump- shaped, present of legs 3 and 4; female spur broadly rounded, on all legs). Coxa 3 sometimes with ventro- distal, rounded process. Femur slightly longer than tibiae 1 and 2, with distodorsal spur; setae implanted on low or vestigial tubercles. Tibiae 1 and 2: setae im- planted on tubercles, which may assume columnar shape. Tarsus short. Propodus with strong heel form- ing right angle with sole, armed with 1 or 2 basal spines and row of thin spinules; propodal lamina very short. Rudimentary auxiliary claws present. Cement gland slightly proximad of middle of dorsal surface of femur of all legs in male, discharging through strong, heavy, tapering, thump-shaped tube directed obliquely distad; length of tube variable: usually as il- lustrated in fig. 70, but in male from Stn. MBT 211 more slender (fig. 71). Measurements (d from Stn. MBT 211) in mm. - Length proboscis (ventral) 1.14; greatest diameter proboscis 0.34; length trunk (frontal margin cephalic segment to tip 4th lateral process) 1.76; width across 2nd lateral processes 1.08. Leg 3: first coxa 0.30; sec- ond coxa 0.96; third coxa 0.46; femur 1.85; first tib- ia 1.78; second tibia 1.82; tarsus 0.15; propodus 0.64; claw 0.49. Etymology. - The specific name, spurius (Latin = illegitimate child) alludes to the dubious taxonomic position of the new species. Remarks. — By the presence of two ventral out- growths on the female proboscis, as well as by almost all points of the general morphology (structure of chela, oviger, shape of propodus, short propodal lam- ina, genital spurs in both sexes...) the present materi- al shows a close similarity to A. stictus Marcus, 1940. The differences with A. stictus pertain to the degree of setosity and tuberculation of legs and lateral processes and to a longer cement gland duct. These characters Jan H.

The length and number of tubercles, processes and spurs fluctuate for instance in À. insignis (Hoek, 1881) (see Stock 1986: 437), whilst the length the cement gland duct is variable in A. petiolatus (vide supra). To com- plicate matters, the material attributed here to A. spu- rius sp. n. is not uniform throughout, but shows marked variability in degree of development of the leg armature and length of the gland tube. Moreover, Bremec et al. (1986: figs. 7-8) illustrate material from Argentina with a distinct tubercle on the lateral pro- cesses (as in A. spurius), but with a low cement gland duct and non-tuberculate legs (as in A. stictus). Therefore, I find it hard to decide whether the present material represents a new species or just ‘a more strongly armed’ variety of A. stictus. I have de- cided to describe it as a new species, mainly to draw attention to the plasticity of the morphological char- acters in this genus. More material will be necessary to decide if the chosen solution was correct. The following expression of character states separ- ates for the moment A. spurius from A. stictus (1) lat- eral processes with tall distodorsal tubercle in spurius, tubercle lower or absent in stictus, (2) coxa 1 with 2 to 10 tubercles in spurius, none in stictus (3) cement gland rather long to long in spurius, short or rather short in stictus, (4) femur and tibiae with numerous long setae, placed on (tall) basal tubercles, in spurius few setae and no basal tubercles in stictus. Comparison with other species. - Child (1979) has described A. reimerae from the Pacific coast of Panama that looks very similar to A. spurius (lateral processes and coxa 1 with tubercles). But À. reimerae has lateral (not ventral) alar processes on the female proboscis, its oviger segments have different propor- tional lengths, and a different terminal oviger seg- ment setation. A. spurius is also very similar to A. sim- ulator Stock, 1975 from Florida, but this species lacks ventral alar processes on the female proboscis (Stock 1986: 440).

Remarks. - This species is known shallow waters, mostly in the upper part of the shelf, of the coast of Brazil (Marcus 1940b, Sawaya 1945) and northern Argentina (de Castellanos 1965; Stock 1966; Bremec et al. 1986). The bathymetrical range of the species is extended by the present records to 250 m. An illustra- tion of the chela is presented here (fig. 62), to allow for proper comparison with A. spurius (see above).

Remarks. - This species is known from almost the entire tropical Indo-Pacific, from Hawaii to the Great Barrier Reef in the east, to the Gulf of Eilat and Madagascar in the west. The only published Atlantic record (Stock 1979) is, like the present records, from Brazil, but in zma there is also a sample from the me- diolittoral zone of Antigua (West Indies). The single available male of the present collection has the cement gland pores arranged in 2 rows on the posterior sur- face of the tibiae. A count of the longest row on leg 4 amounts to about 29 pores. The 3 distal femoral spurs are rather short (as in Stock's 1979, fig. 9c). This is a shallow-water species, found between 0 and 46 m.

Minnaard & Zamponi (1984: 272-275, fig. 11) describe a Colossendeis identified as C. geoffroyi from the “Walther Hertwig 1966 cruise, Stn. 340, 200 m. This station is off Mar del Plata, Argentina (ca. 40°S). Both the rough figures and the measurements provided by the Argentinean authors seem to indicate that a different species is concerned, because the tarsus is almost twice as long as the pro- podus, whereas in all other specimens of C. geoffroyi recorded, there is no great length difference between tarsus and propodus.

Remarks. - The present specimens agree pretty well with the illustrations of R. mediterraneus (cf. Dohrn 1881; Stock 1974), but for a few details that I do not consider of great importance. These differenc- es concern (1) the anterior and posterior spurs on coxa 1 which in some specimens of the present collec- tion are taller; (2) the presence in some specimens of a well-marked tubercle on palp segment 2; (3) a nar- row, unarmed 2nd segment in the palp, vaguely indi- cated in Mediterranean material, is more distinctly present in Brazilian specimens; (4) oviger segments 5 and 6 are subequal (versus 6>5); (5) the posteroven- tral spur on coxa 3 of leg 3 d is less pronounced than Dohrn's figures suggests. The species was recorded before from Brazil by Zago (1970) and Zilberberg (1963). Child (1988a) re-examined some of Zilberberg s specimens and con- cluded that they consisted of a mixture of R. mediter- raneus and À. monnioti. Apart from Brazil, R. mediter- raneus has been recorded from the Mediterranean basin (see Arnaud & Krapp 1990, for references), Madagascar (Stock 1974), off Gibraltar (Stock 1988), 135 ‘TijDSCHRIFT VOOR ENTOMOLOGIE, VOLUME 135, 1992 and the Seychelles (Child 1988a). The present records fall within the known bathymetrical range of the species (1-200 m), except for Stn. MBT 169, which extends this range to 1100 m.

Remarks. — Pycnogonum elephas Stock, 1966, from the same general area (between Rio de Janeiro and Rio de la Plata) is very similar to P. gibberum, but is almost twice as large. Moreover, the tubercles on the lateral processes and on coxa 1 are much less conspic- uous than in P. gibberum, and the proboscis is, espe- cially in lateral view more slender. It is possible that the male of P. elephas lacks ovigers; the male of P. gib- berum has 7- (or 8-2) segmented ovigers. Apart from the three specimens on which the orig- inal description is based, P. gibberum has never been recorded again. The original material came from Ilha Lage de Santos, 32 m (Marcus & Marcus 1963: 6) and Alcatrazes Island, 36 m (Marcus & Marcus 1963: 3), both in Brazil.

Three mid- dorsal bosses near posterior margin of trunk segments 1, 2, and 3; bosses as tall as ocular tubercle; bosses 1 and 2 broadly conical, boss 3 narrower; each boss coarsely tuberculate. Similar bosses on dorsal surface of all lateral processes, that on lateral process 4 tallest. Anterior and posterior margins of lateral processes 2 and 3, posterior margin of lateral process 1, and ante- rior margin of lateral process 4 with 1 or more large tubercles. Abdomen reaching beyond middle of coxa 2 of leg 4, with small tubercles; distally truncate. Proboscis widest near proximal end, slightly taper- ing, distally truncate. Dorsal surface with numerous small tubercles. Oviger 7-segmented; 1 spine on seg- ments | and 2. Distal claw long, sharp, curved. Legs short, thin. Coxa 1 of legs 2 to 4 with large, tuberculate or branched, somewhat upcurved, pro- cesses on dorso-anterior and dorso-posterior surface; coxa 1 of leg 1 with low tubercles only. Coxa 2 not strongly ornamented. Coxa 3 smooth. Femur not widened; with ventroproximal, triangular hump and several large tubercles; dorsodistal end marked by tu- berculate bump and 1 strong seta. Tibia 1 slightly longer than femur, with smaller tubercles and shorter distal seta. Tibia 2 much shorter than tibia 1, about 3 times as long as wide, with some tubercles and rather short distal seta. Tarsus with ventral ‘brush’ of some 7 spinules. Propodus curved, longer than tibia 2; sole evenly armed with some 10 spinules, some of these bifid. Claw curved, less than half as long as propodus; no auxiliary claws. Female: No ovigers. Ornamentation of dorsum and legs slightly less pronounced than in male. Measurements of holotype (mm). - Length pro- boscis (dorsal) 0.71; greatest diameter proboscis 0.34; distal diameter proboscis 0.18; length first trunk segm. 0.73; length second trunk segm. 0.42; length third trunk segm. 0.33; length fourth trunk segm. (to tip lateral process) 0.25; width across second lateral processes 0.74; length abdomen 0.36. Leg 3: first coxa 0.17; second coxa 0.19; third coxa 0.15; femur 0.35; first tibia 0.36; second tibia 0.30; tarsus 0.06; propodus 0.35; claw 0.16. Etymology. - The specific name ornans (Latin = ornamented) alludes to the ornamentation of trunk, lateral processes, proboscis, and certain leg segments with bosses and tubercles. Remarks. - The narrow body shape is reminiscent of P. cessaci Bouvier, 1911 and P. guyanae Stock, 1975. However, P. cessaci possesses small auxiliary claws (absent in the new species), a more barrel- shaped proboscis, whereas the propodal armature tends to concentrate in the distal half of the sole (evenly spread over sole in the species), tibia 1 shorter than the femur and post-ocular tubercles are absent. Both in P. cessaci and in P. guyanae, the coxae and the proboscis are devoid strong tubercles and bosses, so characteristic for the habit of the new species. Although P. letictae de Mello-Leitäo, 1945 is gen- erally considered synonymous with P. cessaci, its pro- podal armature resembles that of the new species. However, by the absence of strong tubercles on the legs, it is clear that the present species cannot be iden- tified with P. leticiae.

Handbog over de i Danmark, Norge, Sverige, Finland og Island forekom- mende arter af Herminiidae og Noctuidae (Lepidoptera). — Danmarks Dyreliv 5: 1-565, 37 colourplates, 530 figs., 469 maps. — [ISBN 87-88757-26-9]. Price DKK 600.- Available from publisher, Apollo Books, Kirkeby Sand 19, DK-5771 Stenstrup, Denmark. This book, part 5 of the series ‘Animal life in Denmark’, deals with the Noctuidae and Herminiidae (traditionally included in Noctuidae) of Denmark, Fennoscandia and Iceland. All 469 species occurring in the area are treated. The text for each species includes paragraphs on diagnostic characters, distribution in general and in detail for the Nordic countries, a distribution map for each species, habitat and biology, including remarks of larval hostplants. For most species the catterpillar is illustrated with a black-and-white photograph, and for some species al- so a photograph of the typical habitat is provided. All species are shown in colour on 37 colour plates, in total showing 1137 specimens in natural size, so giving some impression of variability or sex dimor- phism. These colour plates are made by the well known english photographer David Wilson, who has recently made similar colour-plates for various books on Lepidoptera. The plates are very well photo- graphed, well in focus throughout, and also very well printed: they form the core of the book. Only for the smaller species one wonders if indeed natural size is sufficient to see the sometimes detailed differences. The text unfortunately is in Danish, but with the aid of the english introduction, in which the Danish paragraph titles are explained, people unfamiliar with the scandinavian languages will certainly be able to understand part of the systematic treatment. For identification purposes the text illustrations together with the colour-plates are usually sufficient. 140 Unfortunately the book can only be fully used for the countries listed above: going southwards, soon other species will be found. For instance, in The Netherlands occur about 20 species, not found in ‘Nordens Ugler’. Still the book is a most useful addi- tion to the existing literature on noctuids, firstly be- cause of the beautiful colour plates, much better than in most European literature on the subject, secondly because it contains information on the most recent taxonomic changes, e.g. in Mesapamea and the very recent separation of Noctua janthina and N. janthe. Although a series on all European Noctuidae is on its way (vol. 1 recently being published by the same publisher, and with plates by the same photographer), it will certainly take many years before this is com- pleted. Mr. Skou’s book will therefore fill a gap throughout much of West and Central Europe for several years to come. Further it is a handy book, which could easily be carried when going out for col- lecting. The price is slightly on the high side (with 15% discount if one subscribes to the series ‘Danmarks Dyreliv’), but worth the buy. It is regrettable that it has been decided not to pub- lish an english version, as was done with Peder Skou’s earlier book on the geometroids. [E. J. van Nieukerken] Cherepanov, A.

The discovery of this new species sheds new light on the relationship of Oreagrion with other ischnurines. Correspondence: S. J. Brooks, Department of Entomology, The Natural History Museum, Cromwell Road, London SW7 5BD, U. K. Key words. — Odonata, /schnura, Oreagrion, New Guinea, phylogeny. The ischnurine genus Oreagrion Ris was originally based on a single female collected at 3000 m in the Snow Mountains (now called the Maoke Range) of central New Guinea (Irian Jaya) (Ris 1913). Thirty years later, from the same general area, Lieftinck (1949) described a further three species collected ne- ar Lake Habbema and Mt Wilhelmina (now called Mt Trikora) between 3000-3500 m. Since then no further species of the genus have been described, alt- hough Lieftinck predicted that others would probably be found residing throughout the sub-alpine high- lands of New Guinea. About 700 km to the east of Lake Habbema, in Papua New Guinea, similar tro- pic-alpine conditions occur on Mt Wilhelm and it was here that a fifth species was discovered by George Beccaloni in August 1990. Subsequently, in November, 1991 one of us (SJR) discovered another population on the southern slopes of Mt Capella, in the Star Mountains, central New Guinea. At both localities, no other insects were flying on the cool, exposed slopes, so it is of note that this spe- cies of damselfly can tolerate such harsh conditions. However, Oreagrion species are stout and robust, and the head, thorax, and basal segments of the abdomen have a sparse covering of long, fine hairs which may play a role in thermoregulation. Similar hairs occur in Protallagma, a neotropical genus of ischnurines from the high Andes. Because of the absence of a ventral spine on the 8th abdominal segment in females of Oreagrion, Lieftinck (1949) regarded the genus as the primitive progenitor of Ischnura which it otherwise resembles. However, Oreagrion pectingi sp. n. does possess a ventral spine which throws into doubt Lieftinck’s interpretation of the phylogenetic relationships of the genus. ‘TAXONOMY Oreagrion pectingi sp. n (figs. 1-8) Type material. — Holotype d: Papua New Guinea, Chimbu Province, Mt.

A full description of the terrain is given by Smith (1982). The lake is oligotrophic and appeared to be devoid of higher plants and invertebrates. During August rain may fall every afternoon but up to 22 consecutive dry days have been recorded. Night tem- peratures fall below freezing and day temperatures may exceed 20°C. The holotype and paratype were collected over a shallow seepage trickling through grass, low herbage and bare rocks. The seepage was unshaded and exposed to the wind. Several addition- al zygopterans, probably of the same species, were observed, but not collected, flying in sunshine at the locality. No other odonates were seen. The holotype and paratype were photographed ovipositing in tan- dem into rotting grass stems in about one cm of water. Both male and female had their legs in contact with emerging grass stems during oviposition. The locality at Mt Capella is similar in character. The meadow floor is covered with a thick mat of ferns with clumps of large tree-ferns and stunted rhodo- dendrons. The entire meadow is very boggy and with scattered small areas of open water. O. pectingi occur- red around these pools. The ponds were devoid of ve- getation and supported a depauperate fauna. No Odonata larvae were discovered in the ponds. Temperatures in November fell to 1°C at night and got no higher than 15°C during the day. Individuals flew during brief periods of sunshine. They ceased activity during cloudy or rainy weather. At one pond, about 4 m in diameter, five males rigorously defended territories around the perimeter, chasing off intruding males. Two of these males successfully mated at least once during the three days they were observed. Remarks. — Females of Oreagrion pectingi may be distinguished from other members of the genus by the presence of a ventral spine on the 8th abdominal segment. Otherwise pectingi has similar markings to O. oreadum Lieftinck. However, the lateral lobes of the mesostigmal lamina are rounded in pectingi but narrow and taper apically in oreadum. The abdominal markings of the male pectingi also most closely resemble male oreadum but the pale co- louration is yellow rather than blue-green in the latter species. In oreadum males there is a broad antehumer- al stripe which is absent in pectingi and the pterostig- ma of the fore wing is uniformly brown and lacks the pale apical outer angle of oreadum. The anal appen- dages most readily differentiate pectingi from other Oreagrion species and are not as densely pubescent. However, they are closest in appearance to oreadum. Like this species the superior appendages taper apical- ly but are more acutely pointed in pectingi. The large 144 ventral tooth arises subapically in pectingi, but is api- cal in oreadum. The inferior appendages in oreadum are narrow, directed posteriorly and are considerably longer than the superiors. The inferiors of pectingi are short and bifurcate, although the narrow dorsally di- rected branch is again reminescent of oreadum. Male and female of O. pectingi are considerably larger than oreadum. The similarities of the characters noted above suggest that O. pectingi is most closely related to O. oreadum, which Lieftinck (1949) thought was the most primitive of the Oreagrion species. Lieftinck (1949) considered Oreagrion to be an ischnurine because the males have dissimilar pte- rostigmata in the fore and hind wing and because of certain penile characters, synapomorphies that sugge- st a close relationship with /schnura. However, unlike Ischnura, the females of the four Oreagrion species known to Lieftinck lacked a ventral spine, which implied that they were less derived than /schnura. Nevertheless, in O. pectingi, a fully developed ventral spine is present. If Lieftinck’s assertion is correct, and Oreagrion is a primitive ischnurine, then the ventral spine must have arisen independently once in O. pectingi and again in the /schnura-related ischnurines. Another interpretation of the phylogeny of Oreagrion is that the ventral spine has been secondarily lost in the other four species of Oreagrion, but plesiomorphi- cally retained in O. pectingi. This would imply that, rather than being a stem-group ischnurine, Oreagrion is more closely related to /schnura than Lieftinck sug- gested. However, until more species of Oreagrion are discovered and more work is done on ischnurine phy- logeny this problem will be difficult to resolve.

As our contribution to the Fauna Malesiana pro- gram, we are working on the Nepomorpha and Gerromorpha mainly collected by staff members of the Zoological Museum Amsterdam and the National Museum of Natural History Leiden. The first part of the Gerridae, viz. a revision of the genus Limnometra in the Malay archipelago, was published as the second part of our series (Nieser & Chen 1992a), while Naucoridae, Nepidae and Notonec- tidae appeared in the first part (Nieser & Chen 1991). The specimens studied in this paper were mainly collected by J. P. Duffels, N. Nieser, J. van Tol and G. Zimmermann on several expeditions to Sulawesi, the nearby island of Buton, and to Borneo. For more details (e. g. a list of localities) the reader is referred to Nieser & Chen (1991, 1992a). In addition, unidenti- fied Gerridae from Indonesia kept in RMNH and ZMA have been studied. Dr. D. A. Polhemus (presently at Bishop Museum, Honolulu, Hawaii) is working on a revision of the genus Ptilomera Amyot & Serville. Most of the specimens of this genus taken by the col- lectors mentioned above are at his disposal. A key to the genera of Gerridae occurring in Indonesia and E Malaysia is included. When rele- vant, keys to species of Sulawesi and Buton are given as well. These should be used with caution as the fau- na of the region is still poorly known. Measurements are in millimetres and present the range or the (arithmetic) mean based on five random- ly chosen specimens, or in case there are less than fi- ve, on all specimens available. The width of the head is measured across the eyes, the width of the thorax is measured across the metaacetabula. Most of the females in the samples carried eggs; on- ly where such was not the case this has been indicated. MATERIAL Localities are in Indonesia, unless stated otherwise. The areas in Sulawesi (Celebes) used with the locali- ties agree with the Indonesian provinces, viz. Sulawesi Utara, Tengah and Tenggara for respectively for Northern, Central and Southeastern Sulawesi (see Whitten et al. 1988). Pulau Buton is mentioned se- parately although it belongs administratively to Sulawesi Tenggara.

Aquarius Schellenberg, 1800 This genus is not represented in Sulawesi. The nearest localities where species have been encountered are Sumatera and West Australia (Andersen 1990). 149 TIJDSCHRIFT VOOR ENTOMOLOGIE, VOLUME 135, 1992 Limnometra Mayr, 1865 The Indo-Australian species of this genus have been reviewed recently (Nieser & Chen 1992a). This is essentially a SE Asian and Australian genus with thirty known species of which seven occur in Sulawesi and one on Buton. Sulawesi is the region richest in species for this genus. For a key to the species and other details readers are referred to Nieser & Chen (1992a).

Eyes and apical segment of rostrum shiny dark casta- neous. Interoculus with dark brown V-shaped me- dian mark and margins along eyes. Pronotal lobe with blackish margin all around and a dark median longi- tudinal stripe. Pleura with a dorsal blackish band which is very broad and anteriorly dived in an upper and lower part by a narrow light line on mesopleuron. Ocellated spot dorsally in front of mesoacetabula, dorsal edge of connexiva and lateral margins of abdo- minal tergites dark brown to blackish. Venter with mesoacetabular suture and patch anteriorly black. Some variable and often ill defined brownish marks on meso- and meta- sternum and first abdominal sternum. Sometimes somewhat similar to the pattern in 7. maai Hungerford & Matsuda. Length of antennal segments I : II : III : IV male 2.1 : 1.7 : 2.4 : 2.8; female 1.9 : 1.3 : 1.9 : 2.5. Rostrum moderately slender, reaching slightly over one third of mesosternum. Posterior lobe of prono- tum rather narrow and exposing small parts of meso- notum around its tip. Connexiva rather broad, no connexival spines. Last abdominal segment, however, with a pair of dorsocaudolateral projections, better developed in male than in female, which look like connexival spines. Hind coxae reaching halfway fourth abdominal sternite in male, reaching third in female. Last abdominal sternite as ling as three prece- 150 ding ones. In male last sternite with genital segments as long as preceding part of abdominal venter. Leg measurements, see table 1. Male first genital sternite with a mediocaudal groove bordered by a pair of broad caudally slightly diverging carinae (fig. 6). Ninth segment without ob- vious hair tufts. Endosomal sclerites as in fig 8. Female, caudal margin of last abdominal sternite with small lateral spines and a short, broad median lo- be (fig. 7). Comparative notes. — At first sight very similar to T° pravipes Bergroth (= Limnometra brevis Lundblad, = T. robustus Hungerford & Matsuda, see Polhemus 1991), which lacks, however, the spine like projec- tions caudally on segment 7 an differs in details of ge- nital segments. 7. kampaspe Kirkaldy which has cau- dal projections on 7th segment in male, has these placed more ventrally, has a different colour pattern, and different genital segments. 7. maai Hungerford & Matsuda (= T. quinquemaculata Miyamoto) (see Polhemus 1991), which may look similar and occurs in the same region, is smaller (6 length 5.5 mm, width of thorax 1.64), more slender (over three times as long as wide) and has more pronounced spine-like projections of the last abdominal segment. Etymology. — Akanthinos (Greek adjective mea- ning spinose) refers to the spine like projections of seventh abdominal segment, which differentiate this species from 7. robustus. CYLINDROSTETHINAE Andersen, 1975 Cylindrostethus Mayr, 1865 A tropicopolitan genus, the species live mostly on shaded, quiet parts of streams, like most representati- ves of the genus Aquarius. At first sight, species of both genera are quite similar in size and general sha- pe. Two species have been found in Sulawesi. The comparative notes under C. brachyakanthinos sp. n. will serve to separate them.

Dorsally generally black with conspicuous stripes of silvery hairs at dorsal mar- gins of pleura and ditto dots on acetabula. Median band dorsally on head, thorax and abdomen glabrous in spite of short golden pubescence especially on ab- dominal tergites. Apex of head with dirty yellowish pilosity at sides, becoming blackish with sparse lighter hairs posteriorly. Fulvous spot on base of head and narrow median fulvous stripe on pronotum rather in- distinct. Lateral margins of mesonotum broadly with short thick velvety black pilosity. Outer (upper) mar- gin of connexiva fulvous. Anterior femur black with yellowish base and variable yellowish stripes on inner and outer faces, tibia and tarsus blackish. Middle and hind legs blackish except for coxae and trochanters mainly yellowish. Venter with silvery pilosity on dark base in males; background except for dark spots ante- riorly on thorax, yellowish in females. Length of antennal segments I : II : III : IV, male 1.8: 1.1 : 0.6 : 0.95, female 2.1 : 1.15: 0.6 : 1.0. In dorsal view head longer than pronotum (1.2 in males, 1.4 in females). Pronotum medially depressed. Mesonotum not depressed but with a very thin me- dian groove over its length in female, only in posteri- or part in males. Caudal part of mesonotum in fema- le without oblique ridge. Metanotum flat, its rear margin sinuate. Connexiva slightly less than half the CHEN & Nieser: Gerridae from Sulawesi width of tergites, flaring laterally in males, more or less erect in females (except when abdomen swollen with eggs). Connexival spines short, reaching halfway first genital segment in both sexes, tips not or hardly divergent caudally. Metasternum with lateral groove leading from omphalium, deep and well marked, much more prominent than caudal margin of metas- ternum, which is subequal to or slightly longer than median length of first two abdominal sternites com- bined. Leg measurements, see table 1. Male. Suranal plate in male as shown in fig. 10; wings convex lateroproximally. Last two abdominal sternites of subequal median length, posterior margin of last abdominal sternite evenly concave, posterior margin of first genital sternite slightly produced to nearly straight medially, their median length sub- equal. Parameres and lateral sclerite of endosoma as in fies 11,410, Female. Last abdominal sternite medially slightly longer than penultimate, its hind margin slightly and obtusely produced medially. Macropterous female (apex of hemielytra broken off) as apterous except for development of pronotum and wings. Length 14.5, humeral width of pronotum 2.35, thoracic width 3.25. Hemielytra dark brown with blackish veins. Comparative notes. — Very similar to Cylindro- stethus persephone Kirk., also from Sulawesi. There is a series of small differences: C. brachyakanthinos is slightly larger on average, the fulvous marks on head and pronotum are less distinct, the male abdomen is darker, the posterior part of mesonotum in female is not differentiated. The connexival spines in C. bra- chyakanthinos are shorter (fig. 9), the wings of the su- ranal plate of male are convex basally (straight in C. persephone, fig. 10) and the paramere is broader at ba- se and consequently more tapering in C. brachyakant- hinos (fig. 11). The endosomal sclerites are nearly identical, only the laterals show very small differences in shape (fig. 12). Etymology. — Brachyakanthinos (Greek adjective meaning ‘with short spines’) refers to the short con- nexival spines. EOTRECHINAE Matsuda, 1980 No species of this subfamily have been reported from Sulawesi. Members of this subfamily live rather cryptically on wet places along waters. If any are to be found they will most likely belong to the widespread genus Amemboa Esaki, of which species have been re- corded from Java and Mindanao (Polhemus & Andersen 1984).

Antennae and legs dark castaneous. Mesosternum, metasternum and abdominal venter with dense short silvery pilosity. A broad band of sil- very pilosity on upper part of mesothoracic pleuron extending on dorsum of metaacetabulum.

Median length of mesonotum three times as long as pronotum and metanotum. Fore tibia laterally compressed, with a slight constriction subapically, accentuated by tufts of setae proximally and distally of constriction. Inner apical process bluntly triangular, equally developed in both sexes. First segment of fore tarsus slightly over two times as long as second (table 1). Middle and hind femur of subequal length in both sexes someti- mes middle > hind, sometimes the reverse. Leg meas- urements, see tabel 1. Male. Tergite 7 two times as long as tergite 6, ster- nite 7 caudally broadly and shallowly emarginate. Tergite 8 twice as long as sternite, caudally broadly rounded. Paramere, well developed, rather broad compared to other species in the genus (fig. 40), in rest hidden in the prominent pygophore. Endosoma, fig. 41. Female. Tergite 7 nearly two times as long as 6. Sternite 7 twice as long as 6, with a broad mediocau- dal lobe, in ventral view covering most of the genital segments (fig. 39). Macropterous form as apterous except for develop- ment of thorax and pronotum. Length (including he- mielytra) 10.0-10.2, humeral width of pronotum 2.4-2.5. Pronotum mostly shining black with rough impressed punctures, median length 2.9. Anterior lo- be divided from posterior lobe by a medially inter- rupted ridge caudally accentuated by a groove with some silvery pilosity, posterior part of anterior lobe and anterior part of posterior lobe with a median lon- gitudinal carina. Hemielytra rather membraneous, medium brown with swollen, slightly darker, veins. Etymology. — Anomalos, a greek adjective meaning aberrant. Comparative notes. — P. anomalis differs from other species in the genus by having second antennal segment longer than third and first segment of fore tarsus over twice as long as second. The male has a shorter and broader paramere than other species, the abdominal sternite 7 of the female is quite different from the other species. Remarks. — The macropterous female from ‘Staustufe’ has the hemielytra broken off which seems to be the normal condition in this genus (Hungerford 1957). The macropterous specimens from ‘bridge’ have the hemielytra complete, these are recently moulted specimens, with belly still soft (bending in- ward under slight pressure). Its general form, absence of specialization of the venter in female and presence of claws on middle and hind tarsi place this species in Potamometropsis. This species differs in several charac- ters from all its congeners (see comparative notes). Pending a cladistic analysis of the entire subfamily we refrained from describing a new genus for it. We have seen a teneral female from Sabah, Kg. Sapulut, 116°36’E 4°38’N, leg. Huisman in RMNH, which might belong to another species of this genus but as the abdomen is shrivelled, this material is in- sufficient for a description. CHEN & NIESER: Gerridae from Sulawesi HALOBATINAE Bianchi 1896 Halobates Eschscholtz, 1822 Exclusively marine. Several species live on the open ocean, have wide distributions and are only found near or even on the shore after high winds. Halobates micans Eschscholtz is tropicopolitan and the only spe- cies found in the open Atlantic. It has been recorded from Laut Sulawesi. A second species has been recor- ded from the same area : Halobates germanus White (Herring 1958). These species are easily separated by size, H. micans is over 4-4.5 mm long, H. germanus 3.5-3.9 mm. We have seen two specimens of the lar- gest species in the genus H. princeps which measures 6-7 mm. So far this is the only species recorded from the coast of Sulawesi (Andersen 1991b). The genus was revised by Herring (1961); a survey of phylogeny and evolution is given by Andersen (1991a). Halobates princeps White Halobates princeps White, 1883: 44, pl. 1 fig. 3; Herring 1961: 267-270, fig. 70 (redescription); Andersen 1991b: 158, fig. 8. Material. — Sulawesi Utara, N.

Distribution. — Range included Solomon Isles, N New Guinea, NW Australia, Nusa Tenggara, Malay Peninsula, extreme S of Philippines and Palau (Andersen 1991b). This species has apparently been found on more or less open sea (the type is from ‘Celebes Sea’) and on coastal habitats. Metrocoris Mayr, 1865 Widespread, from the Arabian Peninsula to SE Asia. The species from Malay Archipelago and Philippines have recently been revised by Polhemus (1990). The genus as a whole will be revised by Chen & Nieser (in prep.).

Subgenital sternite large, its median length subequal to the median length of preceding abdomi- nal sternites together, caudal margin sinuate without tongue-like caudal process, apex of abdomen visible in ventral view. Macropterous form unknown. Etymology. — Breviculus (latin adjective meaning rather small) refers to the small size of the species. Comparative notes. — Recognized at once by its small size in combination with yellowish venter, ab- sence of mesopleural stripes and the paramere fig. 22. M. breviculus is 1 mm or more shorter than the only other species occurring in Sulawesi: M. celebensis D. Polhemus. Esakia Lundblad, 1933 Species of Esakia are very similar to Ventidius and Ventidiopsis. The genus is considered by Matsuda (1960) to have evolved from Ventidius by acquiring some specialized characters such as the strongly modi- fied third antenna of the male. Three of the six species known occur in the Malay Peninsula, E. ventidioides Lundblad (1933) was described from Sumatera. Ventidiopsis Miyamoto, 1967 Monotypic; V. imadatei Miyamoto (1967) was de- scribed from N. Borneo (Brunei). Ventidius Distant, 1910 The largest and most widespread genus within this group of small Halobatinae, 16 species have been de- scribed. Greatest species density seems to be in the Malay Peninsula (Cheng 1965, Lansbury 1990) but various regions of its range have been poorly sampled. Ventidius xiphibion sp. n.

Comparative notes. — The bilobed posterolateral angle of metaacetabula, the sexual dimorphism of fo- re femur, asymmetrical parameres and small patch of black bristles on mesosternum of male place this spe- cies in the subgenus Ventidoides Hungerford & Matsuda. V. xiphibion differs from V. pulai Cheng, which has a very similar colour pattern, apart from being slightly larger on average, by lacking a tubercle on fore femur of male, having the patch of minute black bristles on male mesosternum developed, al- though not on a tubercle, and different parameres. The macropterous form of V. pulai has the light mes- onotal spots fused so there is one large central spot. Other Malay species differ in head coloration. Etymology. — Xiphibion (greek: small sword) a noun in apposition refers to the shape of left parame- re. Remarks. — This and the next are the first species of this genus to be reported from Sulawesi. The locali ties where V. xiphibion was taken are small to medi- um sized streams, all three had turbid water due to suspended loam. The species tends to aggregate at places with little current.

Ventral margin of fore femora slightly con- cave, ventral margin of fore tibia nearly straight in fe- male; fore femur with a low hump, fore tibia ventral- ly irregular in male (fig. 24). Leg measurements, see table 1. Male. Parameres nearly symmetrical, fig. 28. In the centre of mesosternum is a small patch of minute black bristles which are not on a tubercle. Endosomal sclerites fig. 31. Comparative notes. — Although the parameres are nearly symmetrical, this species fits best in subgenus Venditioides. V. kurtakalami differs from similar spe- cies by the form of fore tibia in male. Etymology. — Kurtakalami is a Greek noun mea- ning ‘curved shin’ and refers to the structure of male fore tibia. TREPOBATINAE Matsuda, 1960 Metrobatopsis Esaki, 1926 Representatives of this genus have so far only been found in Papua New Guinea and Solomon Isles. CHEN & NIESER: Gerridae from Sulawesi Stenobates Esaki, 1927 Representatives of this genus have been reported fr- om Singapore and Australia (an undescribed species Andersen 1982 fig. 366). Stenobates is very similar to Rheumatometroides, the main difference is in the loca- tion of the metasternal scent gland opening which in Stenobates lies near the anterior margin in the anteri- or extension, whereas in Rheumatometroides the ope- ning lies in the centre of the metasternum. Rheumatometroides Hungerford & Matsuda, 1958 Two species are known from Papua New Guinea and Solomon Isles (Lansbury 1992). Like Stenobates they live on the sea and in estuaries in mangrove and si- milar habitats. We add two new species from Sulawesi: Rheumatometroides makraitos sp. n. (figs. 32-35) Type material. - Holotype d, allotype 2 (RMNH) and 5d 29 paratypes: Sulawesi Tenggara, Teluk Kendari, 13 Mar. 1989, N8947 (Nc, 1d 19 zMA 1d zmc), all apterous. Description Apterous specimens. — Dimensions. Length d 3.7- 4.3, 2 4.0-4.2; width of head d 0.90-0.98, 2 0.93- 0.98; width of thorax d 1.32-1.48, 2 1.66-1.70. Colour, interoculus yellow with dark markings, eyes dark, antennae dark, ventral side of first antennal seg- ment, yellowish. Thorax and dorsum of abdomen yellowish with dark markings (fig. 32). Venter yel- low, legs light brown with dark stripes. Eyes large, about two thirds as wide as interoculus. Antennae shorter (0.6) than length of body, first seg- ment with about 10 suff black setae. Length of anten- nal segments I : II : HI: IV male 1.19 : 0.57 : 0.47: 0.43; female 0.95 : 0.55 : 0.49 : 0.47. Rostrum relati- vely stout, reaching anterior quarter of mesosternum. Pronotum distinctly (0.8) narrower than width of head. Meso and metanotum in females with a very broad mesal, weakly chitinized, sulcus (fig. 32), this is not apparent in males. Fore femur of male only very slightly thicker than in female, ventral margin straight without modifications. Fore tibia flattened and so- mewhat widened apically in both sexes. Mesosternum 6-7 times as long as metasternum, which is not produced anteriorly. Scent gland ope- ning surrounded by a circular structure situated more or less in the centre of metasternum. Male. Pregenital sternite three quarters as long as preceding abdominal sternites together. Sternite 8 slightly shorter than sternite 7, sternite 9 slightly shorter than 8. Proctiger with a pair of long thin ro- stroventrally directed horns (figs. 33, 34). Endosomal sclerites fig. 35. 159 TIJDSCHRIFT VOOR ENTOMOLOGIE, VOLUME 135, 1992 Comparative notes. — There are two further species in the genus: À browni Hungerford & Matsuda from Solomon Isles and New Britain and A. serena Lansbury from Papua New Guinea and New Britain (Lansbury 1992). R. makraitos differs from both by having the yellowish mark on pronotum larger, the female in spite of a broader mesonotal sulcus being relatively narrower and the horns of proctiger of male being relatively shorter. Etymology. — Makraitos, a Greek adjective, mea- ning ‘extended’ and referring to the broad mesonotal sulcus. Remarks. — The species was found on very small and shallow puddles between mangrove air roots. If disturbed they jumped over the wet mud to the next puddle. Despite their small size they are rather quick and, as the net is hampered by the air roots, difficult to catch. Rheumatometroides drepanephoros sp. n.

Proctiger with a pair of relatively short crescent shaped rostroventrally directed horns (fig. 36). Endosomal sclerites fig. 37. Comparative notes. — The appendages of the proc- tiger of male are similar in form, though somewhat shorter, as those in R. serena Lansbury and À. browni Hungerford & Matsuda, which both have a different pronotal pattern with a single median yellowish spot. R. makraitos sp. n. is larger has also a different colour pattern and the proctiger horns are more or less straight. Etymology. — Drepanephoros (Greek adjective mea- ning bearing a sickle or scythe) refers to the form of the appendages of the proctiger in the male. Remarks. — This species was found on a small stre- am with a sand/clay bottom flowing through a coco- nut planation into the bay of Kendari. The plantation is on a very small island, Pulau Nambo, in the bay. This habitat is structurally quite different from the one in which the preceding species was found.

Published 1 December 1992. Poecilimon paros sp. n. from the islands of Paros and Naxos, Greece, is described and illustra- ted. It differs distinctly in calling song and structure of male cercus from its closest relative, Poecilimon hamatus. Dr. K.-G. Heller, K. Reinhold, Institut ftir Zoologie der Universitat Erlangen, Staudtstrasse 5, D-8520 Erlangen, Germany. Key words. — Orthoptera, Phaneropterinae, Poecilimon, taxonomy, bioacoustics, Greece. The genus Poecilimon is the largest bushcricket ge- nus in Europe, containing more than hundred species (including species in the East Mediterranean and around the Caspian Sea). Many species have restric- ted ranges in the mountains of the Balkan peninsula and Asia Minor, but only few are confined to islands in the Mediterranean: P. cretensis Werner, 1903 to Crete and Naxos, ikariensis Willemse, 1982 to Ikaria, aegaeus Werner, 1932 to some Aegean islands, mytile- nensis Werner, 1932 to Lesvos and Limnos and de- planatus Brunner von Wattenwyl, 1891 to some is- lands of the Southern Sporadhes (Willemse 1984). Here we describe a new species, Poecilimon paros, known only from the islands of Paros and Naxos (Kikladhes, Greece) in the Aegean sea. Though close- ly related to P. hamatus Brunner von Wattenwyl, 1878, known from Rhodes and Asia Minor, the new species may be distinguished from the latter by slight differences in morphology, but is readily recognizable by its distinct song. METHODS Calling song and wing movement were registered as described in Heller (1988). For song terminology see Willemse & Heller (1992). Poecilimon paros sp. n.

Bioacoustics. — Male calling song consists of short echemes repeated at intervals of several seconds (mostly 3-5 s). Each echeme (figs. 15-19) consists of a series of wing movements (opening and closing) with increasing amplitude producing a series of syllables with increasing intensity; wing movements repeated regularly except the last movement cycle (and sylla- ble) which is produced after a longer interval than be- tween the previous cycles. Frequency of stridulatory movements within the central part of each echeme between 23 and 28 Hz (body temperature of the ani- mals about 32°C). Number of movement cycles dif- ferent between both individual males (most frequent numbers in different males: 9-10, 11, 11-13, 14; ran- ge 6-15) and circumstances (short echemes during acoustic interactions). The power spectrum of the song showed its peak at about 28 kHz (20 dB below peak 21-42 kHz). Distribution. — Only known from the islands of Paros (500-600 m altitude) and Naxos. Differential diagnosis The new species can easily be distinguished from all other species of the genus except for Poecilimon cervus Karabag, 1950 and P. hamatus, which show also a strongly bifurcate shaped male cercus. In P. cer- vus, known from Central and North Anatolia, the tip of the apical branch of the male cercus has a series of strong spines instead of a single and smaller one in the new species and the inner branch is wider and apical- ly widened instead gradually tapering as in paros (compare figs. 3-5 with fig. 25 in Karabag 1950). However, morphological distinction between the new species and P. hamatus, known from West Anatolia and some adjacent Aegean islands (Willemse 1984), is less obvious. Apparently they represent sis- ter species. Their distinction is mainly restricted to the male cercus: the inner branch in P. hamatus being longer and somewhat more slender (figs. 6-8; Karabag 1950: fig. 26, Willemse 1988: fig. 127, Heller 1984: fig. 2) and the apical branch pointing more outwards with the terminal tooth being smaller and pointing straightly upwards (fig. 10) instead of upwards and at the same time obliquely inwards in the new species (fig. 9). In the female of P.paros the pit of the basal fold of the ovipositor that opens vent- ro-anteriorly is broader and the bordering lobe more prominent than in hamatus. Another difference be- tween both species, present in both sexes, refers to the elytra which in the new species are less covered by the HELLER & rEINOLD: New Poecilimon pronotum and to a greater extent visible than in P. hamatus. However, most obvious and reliable diffe- rences between the two species are found in the struc- ture and duration of the calling songs, defined by the number of movement cycles (opening and closing). In P. hamatus two cycles at most have been registra- ted, the first one often producing only a very faint sound if detectable at all (figs. 20-24; Heller & von Helversen 1986: fig. 3, Heller 1988: fig. 36K). Rarely even a single opening and closing movement was re- corded (fig. 24). These short echemes of P. hamatus differ strongly from those of paros in which at least 6 and commonly 9 to 14 successive opening and clo- sing movements per echeme are produced (figs. 15- 19). Remarks The type locality is the slope of the mountain Agios Ilias-Pantes and can be reached by car using the road from the village of Lefkes to the O. T. E. station (Greek Telegraph Station) on one of the summits. The subadult animals of P. paros were found mainly on Cistus. Their distribution was clustered with so- metimes high population densities of up to 25 ani- mals per m’. Up to now P. paros is the only member of the genus known from Paros. Etymology A noun in apposition, named after the island of Paros. ACKNOWLEDGEMENT We thank Dr. Fer Willemse for his valuable com- ments. REFERENCES Heller, K.-G., 1984.

Macrothele calpeiana (Walckenaer, 1805) was de- scribed early in the 19th century as Mygale calpeiana after a male specimen from the Gibraltar region. Hardly any new records have been published since and Gibraltar (type locality of M. calpeiana), Algeciras (type locality of the junior synonym Mygale luctuosa Lucas, 1855), Malaga and Ronda in Spain, and El-Arouch in Algeria remained the recorded lo- calities of this species until very recently. Then sud- denly and for reasons unknown the species received new attention from two sides independently. Blasco & Ferrandez (1986) produced a substantial morphological and taxonomical account on M. cal- peiana, and settled the discussion on the synonymy of M. luctuosa with M. calpeiana. Blasco & Ferrandez (1986) also presented an updated distribution based largely on recently collected material. Snazell & Allison (1989) published an important paper on the species in which they repeated the dis- tributional and ecological data published earlier by Snazell (1986). They also included and discussed the distribution data of Blasco & Ferrandez (1986) and of others which were not available in 1986. Furthermore they, elegantly, corroborated the synon- ymy of M. calpeiana with M. luctuosa. It appeared that a subadult male of M. calpeiana had not been recognized as such and described as the female of a new species (M. luctuosa), an understandable mistake for any one who knows these animals. Snazell & Allison (1989) presented additional morphological details and information on the prey, a description of the nest and web, observations on courtship and mat- ing in captivity, and finally a description of the sec- ond European representative of the genus, M. cretica Kulczynski 1903. As to its ecology, Snazell (1986) emphasized the re- lationship of M. calpeiana with undisturbed Cork Oak (Quercus suber L.) woodland in the southern- most part of Spain, which he refers to as the optimum habitat for this species. He suggested an apparent in- ability of the spiders to survive in situations more than a few metres away from the woodland, although populations are said to survive on bare banks of roads and streams for some time even though the surround- ing woodland has almost entirely degenerated. Extensive areas of Cork Oak woodland are still present in the region and, he says, there seems to be no immediate problem for M. calpeiana in Spain. However, according to him, intensive cultivation of the woodland and the development of housing pro- jects currently undertaken in the area might become a serious threat. Collins & Wells (1987) picked up this message and, treating M. calpeiana as a bio-indicator for Cork Oak woodland, included the species in their selection of endangered invertebrate species to be list- ed in the Bern Convention. In the same year the spe- cies was placed on Appendix II of the Convention. Not being convinced by Snazell’s (1986) argu- ments for the strict habitat requirements of M. cal- peiana, we decided to carry out an independent sur- vey. The fieldwork was carried out in 1989 by A. E. Decae and A. Hallensleben during two trips to 169 TIJDSCHRIFT VOOR ENTOMOLOGIE, VOLUME 135, 1992 Table 1.

They collected both ecological and distrib- utional data. METHODS A first trip was made in the period between 25 March and 8 April 1989. The coastal region, roughly bordered by the lines Gibraltar-Ronda in the West, Ronda-Lanjarön in the North and Lanjarön-Albunol in the East, was surveyed for the presence of M. cal- peiana. Twenty localities were investigated. In only three localities, all of them West of the city of Mälaga, M. calpeiana was found (fig. 1). Approximately ten specimens were collected (females and juveniles) and taken home for further study. A second trip was made in the period between 17 and 29 September 1989. During this trip attention was focussed on the ecology and natural history of M. calpeiana rather than on the geographical distribu- tion. The region surveyed was largely the same as Snazell’s (1986) study area. Eighty localities were sur- veyed, in 58 of which M. calpeiana was found. In table 1 we have listed all localities where Macrothele calpeina has been found. We have includ- ed information on the relative population densities (number of nests within approximately 20 m’). Fifty adult specimens were collected, among which three adult males. All specimens are deposited in the collec- tion of the Rijksmuseum van Natuurlijke Historie (National Museum of Natural History) at Leiden, The Netherlands. Table 2 lists all the localities where the species could not be found, an equally important observation. In the tables we have listed our localities with a 1X1 km UTM-grid, but visualized the distri- bution on the map with a 5x5 km accuracy. RESULTS Habitat The most western localities visited during the first trip lie within the region where Snazell (1986) found M. calpeiana most commonly and predominantly in association with Cork Oak. The reported frequent occurrence of M. calpeiana in Cork Oak vegetations in that region (mainly cultivated and often fenced in forestland) was confirmed, although dense popula- tions of M. calpeiana were also found in very different situations, such as along roadsides, in picnic areas, in fruit orchards, in pine- and Eucalyptus plantations, on recently burnt grassy slopes, on rubbish dumps, in old stone walls, on cliff faces and even in the Palm- trees of the city parks in Ronda. Further to the East, in the coastal region east of the city of Malaga, an area not surveyed by Snazell, M. calpeiana was not found. This seems to support Snazell’s (1986) remark on the VAN HELSDINGEN & DECAE: Macrothele calpeiana very restricted distribution of M. calpeiana in Spain. During the second trip large and dense populations of M. calpeiana were found, in association with Cork Oak as well as in very different situations. It appeared that M. calpeiana, rather than being dependent on undisturbed Oak-wood, is a culture following species that profits from human modifications of the land- scape. Counts of nests showed that in some of these local- ities population densities reach higher levels than in Cork Oak forests (see tables 1 and 3). Population densities in the relatively undisturbed forests of the ‘Parque Natural Sierra de Grazalema’, the ‘Reserva Nacional de Cortez de la Frontera’ and the ‘Reserva Torrecilla de Serrania’ were found to be lower than in typically man-made habitats such as stone walls and rubbish dumps (see table 3). Table 4 illustrates the relationship of the occur- rence of M. calpeianawith more or less disturbed hab- itats. The following classification was designed for the purpose: Category 1. — Non-cultivated/non-forested: in- cludes the typical mediteranean Garigue with Cistus sp., Thymus sp., Lavandula sp., Trifolium stellatum L., Quercus coccifera L., Chamaerops humilis L., etc., bar- ren mountain passes and exposed river beds; Category 2. — Relatively undisturbed mixed forest: Maquis with Pinus pinea L., Quercus ilex L., Q. suber L., Laurus nobilis L., Pistacia lentiscus L., Ruscus acu- leatus L., Myrtus communis L., etc., with a dense understorey; Category 3. — Cultivated Cork Oak stands: a forest type of almost entirely Cork Oak (Q. suber) from which the understorey is cleared; most of these woods are apparently private property and all are in use for the production of cork; Category 4. — Unmanaged culture land: includes road sides, old walls, rubbish dumps and generally polluted picnic grounds; Category 5. — Managed culture land: includes city parks, gardens, parking lots and development areas. The first two categories contain habitat types which have developed as a result of historical human activities and possible changes in climate but which are currently relatively free of human influences. Reproducing females of M. calpeiana were found in the typical ‘garigue’ (cat. 1) as well as in the dense, al- most inpenetrable ‘maquis’ (cat. 2) type of habitat, but population densities in both these ‘undisturbed’ habitat types were relatively low. Population densities were even lower in the fifth recognized category (managed culture land), although nests of adult spi- ders were found even in such thoroughly maintained places as private gardens, city parks and parking lots. The optimum habitat for M. calpeiana in Southern 1721 TIJDSCHRIFT VOOR ENTOMOLOGIE, VOLUME 135, 1992 Spain obviously lies in terrains that are easily access- ible to man. These habitats, here placed in categories 3 and 4, are either man-made origin or to some extent exploited by man. As far as road sides, old walls and rubbish dumps are concerned this needs no further explanation. Cork Oak woodland is very common and regarded as a natural resource in the region. This leads to a careful management that, as far as our ob- servations go, rarely has adverse effects on the M. cal- peiana populations. In 20 out of the 22 Cork Oak fo- rests thus managed M. calpetana populations were found. In one case, where clearing went as far as bull- dozing all the understorey, M. calpeiana apparently still managed to retain a foodhold by becoming arbo- real. Here numerous webs of adult spiders were found more than 2.5 meters above the ground on the trunks of the Oak trees. Summarizing we may conclude that M. calpeiana thrives on sites with open and accessible soil with some form of shade and cover. Biology Males Adult males have a body length (excluding the spinnerets) of approximately 25 mm. In contrast to most mediterranean Mygalomorphae, males of M. calpeiana are present virtually all year round. Males were collected in the period February - June (Blasco & Ferrandez 1986 and Snazell 1986) and in September (this study). It is not clear if there is a particular mating season. During September fully adult males were found to hunt actively from their own nests. Males of mediter- ranean mygalomorphs more usually abolish feeding to become reproductively active. Females Adult females of M. calpeiana range in body length (excluding the length of the spinnerets) from approxi- mately 25 mm to 37 mm. The relatively large varia- tion in body size of adult females indicates the exis- tence of several year-classes in this group. This in turn would mean that, as is usual in Mygalomorphae, M. calpeiana females are reproductively active for several years after reaching adulthood. Juveniles In September several females were found to have young with a body length of approximately 3 mm in their nests. These juveniles were moving freely in their mothers’ nests and presumably represented the generation which would disperse. Juvenile spiders of intermediate sizes were observed to inhabit individu- al nests. 172 Activity rythms M. calpeiana, unlike most other mediterranean mygalomorphs, is not strictly nocturnal in its activi- ties. Prey-capture was observed both at night and du- ring daylight hours. At night some, but not all spiders in a colony took up positions in the entrance of their nests near the web. Occasionally spiders were obser- ved in this position during daylight. Other activities such as dispersal, nestbuilding, or mating were not observed. The nest The nest of M. calpeiana is composed of an expo- sed ‘sheetweb’ and a set of underground silk tubes. Sometimes the sheetweb is absent and the exposed part of the nest is reduced to a densely woven closed silk cell. The web extends from the nest entrance and may cover an irregularly shaped area up to 1600 cm’. It may be directly attached to the substrate or be sus- pended between low vegetation around the nest en- trance. The web consists of a more or less dense mesh of very fine silk strands spun in an irregular criss-cross pattern. Some aerial strands may extend to some 20 cm above the nest entrance. In general smaller spiders spin smaller webs, although the size and density of the web may vary considerably within all spider size clas- ses. M. calpeiana spins silk continually as it moves. When the spider re-enters the nest after a short sally on the web, it covers the entrance behind itself with a few flimsy strands of silk. The nest entrance may consist of one, two or more silk funnels converging towards the inside of the nest in one main nest tube. The main tube may have one or more flimsy side tubes and is suspended in a pre- existing cavity. This cavity may be a deserted rodent burrow, a rock crevice or washout, a hollow tree etc. Depending on the conditions the main nest tube may extend more than fifty centimetres underground. Indigestible remains of prey are attached to the side tubes or to the outside of the main tube. Prey-capture Natural prey-capture behaviour was not observed. Prey-capture could only be induced in spiders having a sheetweb extending from the entrance of their nests. Those having a closed silkcell at the entrance were not actively hunting and were probably moulting. Skincasts were found both in sheetweb nests and in ‘cellnests’. A whole range of arthropods placed in the web of M. calpeiana induced prey-capture behaviour. The capture behaviour is rather straightforward and ster- eotyped, regardless of the type of prey. Movements of the prey in the web cause the spider to come to the entrance of the nest where it pauses for some time, VAN HELSDINGEN & DECAE: Macrothele calpeiana Table 2.

After a short interval it dashes straight at the prey, grabs it with the fangs and drags it in reverse back to the nest entrance. Prey Captures of the following arthropods were obser- ved: Oniscoidea (two species), Orthoptera, Ceram- bycidae, Staphylinidae, Carabidae, Diplopoda, Scor- pionida. Escaping from the web very quickly was a Scolopendra spec. Snazell & Allison (1989) reported a very broad range of different arthropod prey being captured and consumed by M. calpetana. This strongly indicates general or opportunistic feeding habits of this species and suggests that the availability of food is unlikely to limit the natural distribution. altitude in m. site vegetation type 30 lowlands grass 50 lowlands vine cult. 200 hilltop shrubs 400 highlands shrubs 400 highlands olive/shrubs 450 hilltop olivebush 20 river bed gallery forest 30 creek bed shrub/gallery 40 river bed gallery forest 50 undulating cork oak cult. 160 highlands grass 540 highlands oak forest dense 40 hillside maquis 10 coastal zone cork oak cult. 200 hillside pine 1190 mountain pass shrubs 1050 mountainside barren 1000 highlands pine forest 800 mountainside pine forest 10 lowlands shrubs 400 mountainside barren 700 highlands maquis 300 highlands olive cult. 250 highlands garigue 820 highlands olive cult. 1000 highlands pine forest 800 highlands garigue 100 hillside maquis 200 hillside maquis 100 highlands olive cult. 150 hilltop shrubs/pine 300 highlands olive cult. 20 coastal zone garigue 20 coastal zon road side 900 highlands garigue 1250 highlands cork oak cult. 600 hillside olive cult. 1220 highlands olive cult. 250 highlands olive cult. 30 coastal zone garigue Our investigations of prey remains found in ten webs support this idea. Oniscoidea, Coleoptera and Formicidae constitute the bulk of the prey both in bi- omass and number of individual prey. Interesting is the large discrepancy in the sizes of individual prey animals found in single webs. Remains of beetles with body lengths of approximately 20 mm were found to- gether with the remains of ants of hardly 2 mm. It has still to be investigated if adult spiders catch this ex- traordinary range of prey sizes or that maybe the small prey is captured by juveniles actively hunting in their mother’s web. Very few mygalomorphs are known to capture fly- ing prey. The presence of a bee (family Apidae) re- ported by Snazell & Allison (1989) and a Hymenopteron in one of our samples indicates that M. calpeiana is an exception. 173 TIJDSCHRIFT VOOR ENTOMOLOGIE, VOLUME 135, 1992 Ectoparasites Virtually all specimens collected were heavily infes- ted with Acari which clung in large numbers to the carapace, usually concentrating in the fovea, and sometimes to the abdomen of the spiders. This is in agreement with what Snazell & Allison (1989) found. Numerous mites may be present on one individual without the spider seeming to suffer very much. Spiders kept in captivity were all very quickly free of mites. It is not known what caused the disappearance of the mites. The mite was described by Baker (1991) as a new species of parasitic mite (Androlaelaps pilosus) after specimens collected by Snazell.

Distribution map of Macrothele calpeiana (Walckenaer) with 5x5 km accuracy on UTM-grid; early record from Al- geria indicated. 174 ves certainly has broadened our knowledge of Macrothele calpeiana. Our own investigations affirm and reinforce the distribution pattern which emerges from the literature. But science is exigent and never satisfied. Many questions remain yet unanswered. In Europe M. calpeiana remains restricted to the South of Spain, the region of Andalusia, mainly in the provinces of Cadiz and Malaga. The occurrence in the province of Huelva, based on old and recent records (Blasco & Ferrandez 1986) demonstrates a disjunct distribution with the valley of the Guadalquivir as a possible lowland ecological barrier (open, unshaded, lowland area). The three Huelva records represents the northernmost as well as the westernmost finds so far. The population to the southeast of the Guadalquivir reaches from Malaga in the East to the City of Cadiz in the West and from 37° North lati- tude down to Tarifa, the very southern tip of the pe- ninsula. In this region we may call M. calpeiana a common species. Our attempts to find the species East of Malaga remained without success. However, Barbara York Main from Nedlands, Western Australia, has found a small population (a juvenile and some cast skins were collected) at Las Nimbres, 1.5 km E of Puento de la Mora, at an elevation of 1390 m, in the Sierra Harana north of Granada (Snazell & Allison 1989: 69; also pers. comm.), which means a considerable eastward extension of the known range. The presently known northern limit of the distribution in the province of Malaga at 37° N does not seem a very natural one at first sight and we may expect new records more to the north. The three Huelva records indicate the occurrence on at least the southern slopes of the Sierra Morena. This region, the northern halves of the provinces of Huelva, Sevilla and Cordoba probably is undercol- lected. Which factors limit the distribution of M. calpeia- na is not known. The species seems to prefer cover and shade over exposed open soil. From this we may infer that the animal is sensitive to low and high tem- perature extremes. Humidity may also be a regulating factor. The discovery of populations at higher alti- tudes, where the temperature will be lower on the av- erage, indicates a fair rate of tolerance. We have found a population at 1100 m in a pine forest, on a south- facing slope on a mountain pass at Puerto de la Boya (36°46’N, 5°24’W; province of Cadiz), and another one at 1180 m on a roadside bank on a north-facing slope on a mountain pass near Puerto del Viento (36°48’N, 5°01’W; province of Malaga). The popu- lation established by B. Y. Main at the Sierra Harana at ca 1400 m also proves the ability of M. calpeiana to survive under the climatic conditions at high alti- tudes. Snazell & Allison (1989) stress the correlation of VAN HELSDINGEN & DECAE: Macrothele calpeiana the distribution of M. calpeiana with the area of rela- tively high rainfall (80-200 cm), warm winters and high summer temperatures. They also link the species firmly to oakwoods with the Cork Oak (Quercus suber L.) as dominant species. The Cork Oak has a much wider distribution in Spain and certainly is not restricted to Andalusia. Other parts of Spain than the presently known distribution area of M. calpeiana, in particular the southern slopes of the Sierra Morena, have precipitations about as high as the Cadiz-Malaga mountainous region. This supports the hypothesis of a more extensive distribution along these slopes. Distribution outside Spain Two records from North Africa indicate a wider distribution South of the Mediterranean Sea. The first is an old record from Algeria, where it was found somewhere in the surroundings of El-Arouch in the province of Constantine (Lucas 1846). Our attempts to locate the original material have failed. According to Lucas the species was not common in that locality, where it was found under stones. The second record is of more recent date. A. Blasco collected a single male in 1981 at Ceuta in Spanish Morocco (Blasco & Ferrandez 1986). Even though these two records are spaced out geographically and in time they are sugge- stive of a much wider distribution in the West Mediterranean. The mediterranean zone of North Africa is grossly undercollected and hardly anything is known of the Mygalomorphae of that region. If M. calpeiana would be more wide-spread in North Africa, the geographically restricted occurrence in southern Spain would be easier to understand. The restricted presence in Spain would only be a bridge- head on the European continent from a much larger population in North Africa. The Atlas mountains might offer suitable habitats. Further investigation of this region will throw more light on the distribution. It would not at all be surprising if North Africa harboured a number of Macrothele species. The genus now comprises five species in West Africa, calpeiana and cretica in Europe, and seven more species in India, South-east Asia, China and Taiwan. Most spe- cies have been described after one sex only, usually the female, which shows the paucity of available ma- terial. DISCUSSION M. calpeiana, according to our observations, is not restricted to oak woodland. No undisturbed oak woodlands persist in southern Spain today. All oak- woods, with the Cork Oak (Quercus suber L.) as do- minant tree species, or mixed woods are the result of human interference through mild exploitation during 175 TIJDSCHRIFT VOOR ENTOMOLOGIE, VOLUME 135, 1992 Table 3.

In these semi-natural forests M. calpeiana occurs at low densities if compared to other (unnatural) habitats, such as semi-cultivated Cork Oak woodland with the understorey cleared away, rubbish dumps, roadsides and old walls (table 3). The general impression is that the species benefits from the milder activities of man and makes use of the opportunities thus offered. These observations contradict the opinion expressed by Snazell & Allison (1989: 69), who describe the optimum habitat as un- disturbed Quercus suber woodland with a light under- storey and many large to medium-size stones. Snazell & Allison maintain this view despite the several con- trasting opinions and observations by others and re- ported by themselves in the same publication. We have shown that the population densities outside the Cork Oak woodland are often higher than within. The suggestion of Snazell that M. calpeiana is charac- teristic of undisturbed Cork Oak woodland, and that of Collins & Wells (1987) that it could serve as bio- indicator for that type of habitat has herewith become most unlikely. Apparently the ecological spectrum of this species is very broad. It has been found in a wide variety of habitats. A species which invades new habitats and Table 4.

It is jus- tified to call this species aggressive as to its ecological strategy. Biological strategies, such as the number of offspring, the dispersal of the young, the time and amount of food needed to reach adulthood, and the life-span are unknown so far. It is difficult, if not im- possible, to analyse a possible extension of the distri- bution area in the past. The sequence of the earlier records may be suggestive of a recent colonization of the Iberian Peninsula. However, this is no proof of its speed of dispersal. Nature conservation aspects Snazell’s earlier report (Snazell 1986) on the distri- bution, habitat and status of M. calpeiana in Spain ca- me under the notice of the IUCN Conservation Monitoring Centre at Cambridge (UK) when compi- ling a list of invertebrates to be used in the Bern Convention. They placed the species on their provi- sional list (Collins & Wells 1987) and classified it as ‘vulnerable’, following Snazell’s (1986) description of the species status as ‘fairly secure’ and ‘in no imme- diate danger’ but forseeing as major threat ‘the im- provement of the woodlands or the spread of housing developments’. In the same year (1987) the species was officially placed on Appendix II. This second ap- pendix lists the endangered species the habitat of which should be protected. Most species listed come from the better known groups, such as Lepidoptera, Coleoptera, Odonata, Mollusca, etc. Macrothele cal- peiana is the only spider. In 1991 the Habitat Directive of the European Community has been accepted by the member states. When a country ratifies the Directive it compels itself to take relevant measures for the protection of the list- ed species and their habitats. Macrothele calpeiana is, again, in the appendix to this Directive because the Bern Convention list of Invertebrates served as an ex- ample and was copied without any criticism. Spain thus is obliged to protect the habitat of M. calpeiana as well as the spider itself. The Habitat Directive, in contrast with the Bern Convention, is obligatory: if a country does not satisfy the set rules it can be sum- moned before the European Court. Collins & Wells developed a set of seven criteria for the selection of the species for their list (Collins & Wells 1987). First of all (1) the species should be under serious threat (endangered or vulnerable) or of widespread conservation concern. Since the list is to be used as an appendix to the Convention on the Conservation of European Wildlife and Natural Habitats, generally known as the Bern Convention, (2) the species’ range in Europe should not be margi- nal to a much wider range outside Europe. The Bern Convention has political significance in the first place VAN HELSDINGEN & DECAE: Macrothele calpeiana Fig. 2. Macrothele calpeiana (Walckenaer) on its web and this has led to the suggestion that (3) the species must be reasonable easy to identify, and preferably fa- miliar to members of the general public. Even though challengeable on evolutionary grounds one can understand that (4) in line with other listings in the Appendices to the Convention only full species should be considered. This is not a criterion, but a practical rule. There are three more criteria which in fact are recommendations of the compilers of the lists for the different appendices: the final selection of spe- cies (5) should come from a wide range of habitats, particularly threatened ones, and (6) from a wide va- riety of phyla and classes, while it should also (7) em- brace a wide geographical range. When judging a single species on the list one has to consider criteria 1 to 3. If we do this with M. calpeia- na, we easily arrive at the conclusion that the species should not at all be listed in the Bern Convention. We have pointed out that this spider is not under threat, endangered or vulnerable in its relatively small Spanish range of distribution. It is not strictly tied to any specific habitat, but can be found in a wide varie- ty of, often man-made, habitats. We have presented arguments in support of the hypothesis that the spe- cies has also a wider distribution outside Europe. Thus we find the first two criteria not applicable to M. calpeiana. Remains the third criterion. M. calpeiana is a large, black spider, upto to 7 cm long (legs included), with two conspicuous ‘tails’, the spinnerets, at the end of its abdomen (fig. 2). The general public at the most will know its large web. The animal itself leads a cryp- tic life in its burrow. It is the only spider of this size, shape and habits that lives in the area and is quite conspicuous when seen (e.g. by the people who man- age the oak forests). We already indicated above that this criterion is a political rather than a scientific one. It has practical implications for the enforcement of any directives in relation to the Bern Convention. For a matter so serious as the protection of Invertebrates and their natural habitats, however, this criterion has no meaning. A species becomes threatened with extinction usu- ally through the activities of man. The threat is aimed either directly at the animal, e.g. by hunting, over- fishing or the use of selective biocides; or indirectly through the many drastic changes in the environ- ment, such as extensive drainage schemes, the bring- ing into cultivation of natural habitats, the use of un- selective biocides, the cutting down of forests, the construction of motorways and town-development. In the case of Invertebrates the indirect factors are usually the cause of threat. Stenoecous species with very strict habitat or food requirements are more vul- WHY, TIJDSCHRIFT VOOR ENTOMOLOGIE, VOLUME 135, 1992 nerable than euryoecous species which can live nearly anywhere. When a habitat is scarce and deteriorates by one of the above influences all species narrowly adapted to that habitat are threatened. If one wishes to protect such a species one has to protect or restore the habitat in general or a site in particular by ward- ing off the threatening forces. It is the general practice in nature conservation legislation to protect a habitat through the species, i.e. the species is named and the law compels that the habitat or site be protected or managed in such a way that the species can survive. It is a good policy to select a species of which the biology and ecology are well known, the distribution is properly mapped, and the densities measured. It must be feasible to monitor the species and follow the developments and the results of the measures eventu- ally taken. The selection of the species should be based on such (scientific) arguments, not on the pos- sible recognition by the general public. The general public should be interested in the lasting biological diversity in general and support politicians to develop legislation and give priority to nature conservation. The general public must be kept informed in general terms of the progress made. In our view the third cri- terium should read as follows: “The species must be taxonomically unambiguous and sufficiently defined as to its biology and ecology. At the same time the reasons for its decline should be fully understood’. Species such as M. calpeiana then would not be listed in the Bern Convention. Future research As we have pointed out the distribution in Spain is as yet not clearly established, especially in the East and Northwest. Further investigation should focus on these regions, in particular the southern slopes of the Sierra Morena and the Sierra Harana north of Granada, and possibly the Sierra Nevada as well. It would also be an enticing project to investigate the northern countries of Africa, from Morocco to Algeria, or even further to the East. Investigation in this region will throw more light on the distribution of M. calpeiana. 178 REFERENCES Audouin, J. V., 1826.

Key words. — Brazil, Neotropics, Cyclocephala, new species, new country records. In this paper are described new species and records of Cyclocephala that I collected during my stay in Brazil from 1976-1978, from collecting trips taken in 1980 and 1991, and from specimens either given or loaned to me in the interim. Each new species has been correlated with the most recent key to the genus provided by Endrédi (1985) in order that the reader might know where they fall out in the key. Appropriate notations can then be made for future re- ference. The parameres of the males, diagnostic in vir- tually all cases, are illustrated and accompanied by photo habitus pictures or line drawings to clarify the descriptions of body morphology. Several new country records are also listed. Although I and a few others have known of these oc- currences for several years, they have never been for- mally placed into the literature. The purpose of lis- ting these records is to provide an enhanced level of reliability concerning identification of taxa that fall outside of the previously published ranges. Specimens have either been borrowed from or de- posited in several collections. These collections are re- ferred to by their four-letter acronyms as published in Arnett and Samuelson (1986) or as indicated here if not in Arnett and Samuelson: BCRC - Brett C.

Head: Surface moderately densely punctate; punc- tures on frons and basal half of clypeus small, punc- tures on apical half of clypeus minute and denser. Clypeus (fig. 9) with sides weakly converging, apex broadly truncate, narrowly reflexed. Interocular width 3.3 transverse eye diameters. Antenna with 10 segments, club subequal to segments 2-7. Pronotum: Surface with punctation similar to that of frons. Base lacking marginal line. Prosternal pro- cess only moderate in length, obtusely rounded at ap- ex. Elytra: Surface minutely alutaceous, moderately densely punctate; punctures moderately large, shal- low, with double rows on disc. Sparse, minute, pale setae present, especially in posterior half. Pygidium: Surface completely, finely rugulose with sparse, minute, pale setae. In lateral view, surface we- akly convex. Legs: Foretibia bidentate, both teeth close to each other at apex of tibia. Foretarsus (fig. 10) with seg- ment 4 expanded ventrally as a strong tooth; segment 5 greatly expanded for entire length, wider at base 180 than at apex. Claw immensely expanded, subtriangu- lar, apex entire. Posterior tarsus almost twice as long as posterior tibia. Parameres: figs. 11-12. Female allotype. — Length 12.6 mm; width across humeri 5.6 mm. As holotype except in the following respects: Head: Clypeus in apical half with punctures not smaller, instead subequal in size to those on rest of head. Elytra: Lateral margin slightly diluted at about middle and with strong, protuberant knob at about level of apical umbone. Pygidium nearly flat in lateral view. Legs: Foretibia tridentate, teeth equally spaced from one another. Foretarsi and claw not en- larged. Variation. — Males (18 paratypes). Length 12.3- 14.0 mm; width across humeri 5.5-5.9 mm. The pa- ratypes do not differ significantly from the holotype. Females (14 paratypes). — Length 12.1-13.5 mm; width across humeri 5.4-6.1 mm. The females are also remarkably similar to the allotype with no signi- ficant differences noted. Distribution Cyclocephala amplitarsis is known from primary lowland rainforests in central Rondonia and north- western Mato Grosso in Brazil. All specimens were ta- ken at lights, and one (collected by Jorge Arias) was taken at a CDC light trap suspended at a height of 6 m. Remarks The enlarged foretarsi and claws of C. amplitarsis bring to mind C. longimana Dechambre, 1980 and C. tarsalis Dechambre, 1979, but those species have a bordered pronotum as well as many other different character states. Cyclocephala amplitarsis will key only so far as couplet 239 (242) in Endrödi (1985) (if the surface is considered setose, couplet 221/272) where neither choice concerning foretibial teeth fits the cle- arly bidentate state of this species. If the elytra are considered to have short setae (lat- ter half of couplet 221/272), then C. amplitarsis will go as far as couplet 328/337 where neither choice (concerning tridentate foretibia) is acceptable. Etymology From the Latin amplus, meaning large and the Greek tarsor, meaning flat of the foot; large foot, a noun in apposition in reference to the greatly swollen foretarsi of the male. Cyclocephala boulardi Dechambre This species was described from Surinam, and the following new country record from Brazil is not surpri- sing in view of the relative affınities between the fau- na of northern Brazil and the Guianas.

Description Male holotype (fig. 2). — Length 18.0 mm; width across humeri 8.0 mm. Colour of clypeus, pronotum, scutellum, pygidium, legs, and venter piceous; frons black as well as all elytral margins (expanded into bro- ad triangle behind scutellum), elongate spots on hu- meral and apical umbones, and punctures on elytra. Remainder of elytra testaceous. Head: Frons and base of clypeus moderately dense- RATCLIFFE: New Brazilian Cyclocephala ly punctate; punctures moderate in size. Fron- toclypeal suture a distinctly impressed, biarcuate line. Clypeus in apical 2/3 finely and completely roughe- ned; sides barely converging to very broad, truncate apex, apex reflexed. Interocular width 3.0 transverse eye diameters. Antenna 10-segmented, club subequal in length to segments 2-7. Pronotum: Surface moderately punctate on disc, becoming a little denser on sides; punctures small on disc, becoming moderate in size on sides. Base lacking marginal line. Prosternal process short, mostly obscu- red by brush of long setae. Elytra: Surface with moderate to large punctures in striate rows, double rows of punctures distinct; sur- face, especially posterior half, with minute, moderate- ly dense, reddish brown setae. Pygidium: Surface co- arsely shagreened, setigerous; setae reddish brown, minute at base, short on disc and moderately long ne- ar apex. In lateral view, surface evenly convex. Legs: Foretibia bidentate, both teeth close to one another near apex of tibia. Foretarsus with segment 5 (claw segment) greatly expanded for its entire length (fig. 13), wider at base than at apex. Claw of foretar- sus enlarged, apex entire. Posterior tarsus about twice as long as posterior tibia. Parameres: figs. 14-15. Distribution Cyclocephala deltoides is known only from the Urua locality in Brazil’s Amazon National Park, which was just being established in 1977. It was taken at lights on a road cut in primary lowland rainforest near the end of dry season. Remarks Like Cyclocephala amplitarsis described elsewhere in this paper, the enlarged foretarsi also resemble C. longimana Dechambre and C. tarsalis Dechambre, but those species have a margined base of the prono- tum as well as other different character states. Cyclocephala deltoides most closely resembles C. amp- litarsis but differs from it in greater body size, smaller size and different form of the foretarsal claw in males, different form to the parameres, tricoloured body (black, piceous, testaceous), larger eyes, longer and denser pygidial setae, and with larger and more dis- tinctive elytral punctures. If the elytra are considered setose (Endrédi’s cou- plet 221/272), then C. deltoides will key only to cou- plet 239/242 where neither choice of foretibial teeth works. If the choice is made for the second part of couplet 221/272 (species with very short elytral setae), then this species keys to couplet 328/337 whe- re neither choice (concerning tridentate foretibia) works. 181 TiJDSCHRIFT VOOR ENTOMOLOGIE, VOLUME 135, 1992 12 13 14 19 16 18 Figs. 9-12.

Legs: Foretarsi not enlarged. Distribution Cyclocephala iani is known only from Reserva Campinas (Instituto Nacional de Pesquisas da Amazonia) north of Manaus. This region is characte- rized by lowland rainforest mixed with islands and peninsulas of white sand soils (campinas) and associa- ted low vegetation (campinarana). This soil/ vegeta- tion type, known as campinas amazonicas (Anderson et al. 1975), is where the reserve takes its name. Remarks In Endrödi (1985), both sexes of C. ani will key to C. undata (Olivier) in their respective parts of the Cyclocephala key (329/330 for males, 297/298 for fe- males). The significant differences between them, however, clearly indicate they are not conspecific. The differences are primarily in the sculpturing of the cly- peus, frons, and pronotum and especially in the form of the parameres of the male. The parameres, in fact, most closely resemble those of C. picipes (Olivier), but other characters of clypeal shape, surface sculpturing, and colour patterns separate the two. Etymology I am pleased to name this species after my youngest son, Ian, who has so faithfully assisted me in the field while collecting beetles. Cyclocephala longa Endrödi Endrédi (1963) described this species from Bolivia. The locality data listed below, actually just across the border from Bolivia, is a new country record. Brazil, Rio Branco, 25-vi-1962, Hawarth collector (1 male in BCRC ). Cyclocephala munda Kirsch Although widely scattered over northern South America (Surinam, Colombia, Peru; Endrödi 1985), 183 TIJDSCHRIFT VOOR ENTOMOLOGIE, VOLUME 135, 1992 C. munda has not been recorded from Brazil. The fol- lowing is a new country record. Brazil: Amazonas, Reserva Campinas, 60 mi N Manaus, 14-1-1977, B. C. Ratcliffe (1 male in BCRC ); Amazonas, 15 km SE Barcelos, 14-1-1978, N.D.

Distribution Cyclocephala nodanotherwon is known only from Lake Anama WSW of Manaus. Remarks This species will key to either couplet 298 (C. gra- vis Bates) or 306 (C. munda Kirsch) in Endrôdi (1985) depending on the interpretation of the degree of punctation on the pronotum (couplet 299). In eit- her case, however, neither the parameres, vestiture, or surface sculpturing conforms to that of C. nodan- otherwon. The examples of this new species were collected by Robin Best (deceased), a colleague of mine at Brazil’s National Institute of Amazonian Research (INPA), while conducting research on manatees at Lago Anama. Etymology This new species name is the result of an arbitrary combination of letters (hence, treated as an indeclina- ble noun) and results in a species name not inapprop- riate in such a large genus. Cyclocephala ocellata Burmeister Known previously from Ecuador and Peru (Endrédi 1985) and French Guiana (Dechambre, 1979), the following represents a new country record. Brazil: Amazonas, 46 km N Manaus, 1-29-viii- 1979, H. M. Savage (1 female in BCRC ). Cyclocephala panthera Dechambre Dechambre (1979) described this distinctively marked species from a single male specimen taken in Para State, Brazil. I report here ten additional speci- mens from the Canadian National Collection of Insects that verify the valid status of Dechambre’s species. The specimens (six males, three females) are labelled BRAZIL: Distrito Federal, Estacion Florestal Cabeca do Veado, 1100 m, 13-27 Oct. 1971, E. G., I. & E. A. Munroe. The previously unknown females have the elytral margin in the posterior third slightly (but distinctly) thickened. In Endrédi’s (1985) key to female Cyclocephala, it will key as far as couplet 261. Couplet 262 should be modified as follows: 262 (263) Surface bare. 262a. Head and pronotum piceous, elytra with variable pattern (Figs. 270, 273).

Ratcliffe.’ Holotype and allotype deposited at UNSM. Paratypes deposited in BCRC . Description Male holotype. — Length 9.4 mm; width across hu- meri 4.8 mm. Body form short, oval. Colour testace- ous except for black frons. Head: Surface of frons coarsely alutaceous with moderately dense and moderately large punctures. Clypeus with similar punctation mostly obscured by surface roughness; sides subparallel, apex broadly truncate, narrowly reflexed (fig. 20). Interocular width 2.15 transverse eye diameters. Antenna 10-seg- mented, club subequal to segments 2-7. Pronotum: Surface finely alutaceous with punctu- res moderate in density; punctures moderate in size along midline, becoming moderately large on disc and sides. Base without marginal bead. Prosternal process long, posterior face at apex flattened. Elytra: Surface finely alutaceous with moderate to large, shallow punctures, double rows of punctures al- most indistinct. Pygidium: Surface densely punctate, punctures small. In lateral view, pygidium evenly convex. Legs: Foretibia (fig. 21) tridentate, basal tooth slightly removed from other teeth. Claw of foretarsus with apex deeply split (fig. 22). Posterior tarsus sub- equal in length to posterior tibia. Parameres: figs. 23-24. Female allotype. — Length 10.6 mm; width across humeri 5.2 mm. As holotype except in the following respects: Elytra: Lateral margin slightly expanded just behind middle. Pygidium: Surface weakly convex, ne- arly flat. Legs: Foretarsus with claw not enlarged. RATCLIFFE: New Brazilian Cyclocephala Variation. — Males (2 paratypes). Length 11.1-12.0 mm; width across humeri 5.5-5.8 mm. The paratypes do not differ appreciably from the holotype. Distribution Cyclocephala pseudoconfusa is known only from the type locality north of Manaus. This is an area of whi- te sand soils (campinas) that occur in peninsulas or patches. This particular soil/vegetation type was char- acterized by Anderson et al. (1975). Remarks This small, oval species will key as far as couplet 405 (404) in Endrödi (1985) which is C. confusa Endrödi. While fitting in all respects to the characters listed in the couplet, the parameres are vastly diffe- rent. The same can also be said for the similarity in external characters with C. perconfusa Dechambre, 1992. These three species should cluster together in any key and be separable only by the form of the pa- rameres in the males and the presence or absence of an expanded elytral margin in females (margin simp- le in C. perconfusa, with slight expansion in C. confu- sa and C. pseudoconfusa).

Double rows not evident. Pygidium: Surface minutely shagreened, moderate- ly punctate; punctures small, shallow to indistinct. Sparse setae present at base. In lateral view, surface re- gularly convex. Legs: Foretibia tridentate, basal tooth simply a we- ak angulation, teeth subequally spaced. Foretarsus en- larged, large claw with apex entire. Posterior tarsus twice as long as posterior tibia. Parameres: figs. 25-26. Female allotype. — Length 8.7 mm; width across humeri 3.8 mm. As holotype except in the following respects: The black, elytral vitta reduced to 2 weakly connected, elongate spots. Head: Punctures strong and distinct over entire surface. Elytra: Punctures dis- tinct. Margin slightly expanded at middle. Pygidium: In lateral view, surface nearly flat. Legs: Foretibia dis- tinctly tridentate, teeth subequally spaced. Foretarsus and claw not enlarged. Variation. — Females (2). Length 8.8 mm each; width across humeri 3.9 mm each. Except for the elytral markings being reduced to 2 small, separate spots, the females do not vary significantly from the allotype. Distribution Cyclocephala rondoniana is known only from the lowland rainforests on the Schmitz farm in Rondonia, Brazil. Remarks This species will key only so far as couplet 203 (202) in Endrödi (1985), after which nothing fits. The parameres appear closest to C. quadripunctata Höhne and C. peruana Endrödi, but those species lack a marginal line on the base of the pronotum. The oblique line on the elytra of the holotype is distincti- ve although this is reduced to two spots in the three females. Etymology The proper name of the territory of Rondonia has been converted into a noun in the genitive to indica- te ‘of Rondonia.’ Cyclocephala sarahae sp. n. (figs. 6, 27-28) Type material. — Holotype à, allotype ® and single pa- ratype labelled ‘BRASIL: Amazonas, Rio Demeni nr. RATCLIFFE: New Brazilian Cyclocephala equator, IV-10-1978, L. R. Lacey.’ Holotype and allotype deposited at UNSM; paratype deposited in BCRC . Description Male holotype (fig. 6). — Length 11.4 mm; width across humeri 6.2 mm. Colour reddish brown except for black frons and testaceous elytra. Form short, oval. Head: Surface of frons moderately punctate (more so in anterior half); punctures moderate in size, deep. Frontoclypeal suture distinct, sinuate. Clypeus with surface transversely rugopunctate; sides convergent to broad, subtruncate apex, apex reflexed. Interocular width 2.25 transverse eye diameters. Antenna 10-seg- mented, club a little longer than segments 2-7. Pronotum: Surface moderately punctate, beco- ming densely punctate on sides; punctures deep, mo- derately large on disc, becoming large on sides. Posterior angles broadly rounded. Base without mar- ginal line. Prosternal process long, flattened at apex on posterior half. Elytra: Surface with large, shallow, umbilicate punctures; punctures not in distinct rows, surface be- tween punctures minutely alutaceous and shining. Pygidium: Surface similar to that of pronotum with moderately dense and moderately large punctu- res on disc, punctures becoming denser and larger on sides and base. In lateral view, pygidium strongly con- vex. Legs: Foretibia tridentate, basal tooth distinctly re- moved from others. Foretarsus with 1 claw strongly enlarged, apex finely cleft; smaller ramus of claw not widely divergent from larger ramus. Posterior tarsus short, subequal in length to posterior tibia. Parameres: figs. 27-28. Female allotype. — Length 13.5 mm; width across humeri 7.4 mm. As holotype except in the following respects: Head: Frontoclypeal suture broader, deeper. Clypeus with surface more coarsely rugopunctate. Elytra: Lateral margin barely expanded at about mid- dle. Pygidium: Surface densely punctate on disc, be- coming rugopunctate on base and sides. Convexity weak. Foretarsus with claw not enlarged. Variation. — Male (1 paratype). Length 10.3 mm; width across humeri 5.6 mm. The single paratype does not differ appreciably from the holotype. Distribution Cyclocephala sarahae is known only from the ‘type locality’ on the Rio Demini north of Barcelos (a tri- butary of the Rio Negro above Manaus). Remarks This species is externally similar to C. bicolor Castelnau (couplet 408/409 in Endrôdi, 1985) ex- cept that the large foretarsal claw is finely split in C. 187 TIJDSCHRIFT VOOR ENTOMOLOGIE, VOLUME 135, 1992 sarahae and broadly split in C. bicolor. The parameres are also vastly different; in fact, no known species of Cyclocephala has parameres even remotely resembling those of C. sarahae. Cyclocephala sarahae will key as far as couplet 404/405 in Endrödi (1985) which is C. te- stacea ab. ovulum Bates. Cyclocephala testacea ab. ovul- um has much simpler parameres, has the basal tooth of the foretibia barely separated from the others, and is not distinctly bicoloured as in C. sarahae. This new species was collected by a colleague, Larry Lacey, while we were both working for Brazil’s National Institute for Amazonian Research (INPA). During a boat trip upriver by Lacey, periodic stops were made to spend the night, hence the imprecise lo- cality information. Etymology I am pleased to name this species after my daugh- ter, Sarah, who, even though she was not quite three years old at the time, nevertheless helped me to col- lect Amazonian insects during our stay in Brazil.

Paratypes at CASC, MZSP, UCDC, UNSM, USNM, PKLC, DERC, LGBC, HAHC, MAMC, and BCRC . Description Male holotype (fig. 7). — Length 11.7 mm; width across humeri 5.0 mm. Colour testaceous with pice- ous tarsi and 3 small, black elytral spots (1 behind hu- merus, a larger, oblique, elongate spot mesad of that, and 1 in centre of elytron behind middle). Head: Surface minutely alutaceous, moderately densely punctate; punctures small, becoming smaller and denser at clypeal apex. Clypeus with apex nar- rowly parabolic, reflexed. Interocular width 3.0 trans- verse eye diameters. Antenna with 10 segments, club subequal in length to segments 2-7. Pronotum: Surface similar to that of frons except punctures slightly larger and sparser on disc. Base with marginal line. Prosternal process short, conical. Elytra: Surface with moderately dense, large, very shallow punctures, double rows on disc barely evi- dent; a few, short, pale setae present on apical half in barely discernible rows. 188 Pygidium: Surface roughened with moderately dense, short, reddish brown setae. In lateral view, sur- face convex. Legs: Foretibia bidentate. Foretarsus expanded in size, claw bearing segment greatly enlarged at base on medial surface (fig. 29), larger claw with apex entire but bearing small tubercle subapically. Posterior tarsi about 1.8 times longer than posterior tibia. Meso- and metatibia with stout (not bristle-like) setae. Parameres: figs. 30-31. Female allotype. — Length 11.0 mm; width across humerus 4.8 mm. As holotype except in the following respects: Flared region of elytral margin black. Head: Punctures slightly larger and denser. Elytra: Lateral margin expanded just behind middle. Pygidium: Surface glabrous, less convex. Legs: Foretibia triden- tate, basal tooth only a weak angulation, all teeth sub- equally spaced from one another. Variation. — Males (13). Length 10.7-12.3 mm; width across humeri 4.8-5.2 mm. The paratypes are all similar to the holotype except that the size of the elytral spots varies slightly (1 example with spots ne- arly obsolete), and the Surinam specimen has the cly- peal apex a little less narrowly rounded. Females. (23). — Length 11.0-12.8 mm; width across humeri 4.8-5.5 mm. The female paratypes do not differ significantly from the allotype. Distribution Cyclocephala sarpedon is known from the lowland rain-forests of central Rondonia and northwestern Mato Grosso states in Brazil and from north-central Surinam and north-central Venezuela. All specimens were collected at lights. Remarks The specimens of the type series are remarkably consistent in expression of their character states. The narrowly parabolic clypeal apex, bidentate tibia, and the form of the male parameres are diagnostic for this species. It is very close in appearance to C. schmitzo- rum, but the size is generally smaller, the parameres differ in shape (usually difficult to see due to dense setae on the parameres), and the males have the fifth tarsomere greatly expanded at the base medially (fig. 29). Like C. schmitzorum, this species will key only so far as couplet 193 (196) in Endrödi (1985) where, af- ter that, character states no longer fit. Etymology Named after Sarpedon, a son of Zeus and Europa and king of Lycia who was killed in the Trojan War … and also because it was the very first epithet in a scientific name (Graphium sarpedon) that | learned as a boy. I’ve liked the sound of that word ever since. Cyclocephala schmitzorum sp. n. (figs. 8, 32-34) Type material. — Holotype d, allotype 2, and 5 para- types labelled ‘BRASIL: Rondonia, 62 km S. Ariquemes, Faz. Rancho Grande, 10° 32’ S, 62° 48’ W, XI-11-22-1991, B. C. Ratcliffe, collected at light.’ Five additional paratypes with same data except collected by L. G. Bezark and D. E. Russell, and Brasil: Amazonas, Reserva Ducke, 26 km NE Manaus, 11-xi-1976, B. C. Ratcliffe (1); Suriname, Raleigh Falls, 25-27-vii-1975, Coll: D. Engleman (1). Holotype and allotype deposited at UNSM. Paratypes at USNM, CASC, DERC, and BCRC . Description Male holotype (fig. 8). — Length 13.1 mm; width across humeri 5.8 mm. Colour testaceous with pice- ous tarsi and small, black elytral spots (1 behind hu- merus, a smaller one mesad of that, and 1 in centre of elytron just behind middle). Head: Surface minutely alutaceous, moderately densely punctate; punctures small, becoming smaller and denser at clypeal apex. Clypeus with apex nar- rowly parabolic, reflexed. Interocular width 3.0 trans- verse eye diameters. Antenna with 10 segments, club subequal in length to segments 2-7. Pronotum: Surface similar in sculpturing to frons, punctures a little sparser on disc, becoming a little lar- ger and denser in posterior angles. Base with comp- lete marginal line. Prosternal process short, conical. Elytra: Surface with moderately dense, large, shal- low punctures, double rows on disc evident; 6 rows of setae present (1 sutural row, 2 rows on disc, 2 on side, 1 on lateral margin); setae short, stout (almost bristle- like), reddish brown, sparse. Pygidium: Surface completely roughened, with moderately dense punctures; punctures small, setige- rous; setae dense, long, reddish brown. In lateral view, surface weakly convex. Legs: Foretibia bidentate. Foretarsus expanded in size (fig. 32), larger claw not split at apex. Posterior tarsi about 1.6 times longer than posterior tibia. Meso- and metatibia with bristle-like setae. Parameres: figs. 33-34. Female allotype. — Length 13.2 mm; width across humeri 6.0 mm. As holotype except in the following respects: Expanded region of elytral margin is black. Elytra: Only a few setae present in apical half, rows absent. Lateral margin dilated at level of first sternite with swollen tumosity on side just above margin. Pygidium: Surface glabrous. Legs: Foretibia tridenta- te, basal tooth only a weak angulation, all teeth sube- qually spaced from one another. Variation. — Males (5). Length 11.2-13.2 mm; width across humeri 5.4-6.2 mm. The male paratypes do not differ significantly from the holotype. One specimen has the elytral setae reduced or abraded away on the anterior half. RATCLIFFE: New Brazilian Cyclocephala Females (2). — Length 12.0-12.9 mm; width across humeri 5.8-6.0 mm. The female paratypes are similar to the allotype. Distribution Cyclocephala schmitzorum is known from primary lowland rainforests in central Rondonia and by a single specimen each from near Manaus, Brazil and north central Surinam. All specimens were taken at lights. Remarks Although apparently subject to some abrasion, the presence of almost bristle-like setae in rows on the elytra in combination with the narrowly parabolic clypeal apex, bidentate tibia in the male, and form of the parameres will distinguish this species. It is very close in overall appearance to C. sarpedon, but the si- ze is slightly larger, the parameres differ (often diffi- cult to see due to the dense pilosity on the parameres), and the enlarged claw joint in the males is not flared at the base (fig. 32). If the elytral surface is considered setose (couplet 183/174 in Endrédi 1985), then it will key to couplet 193 (196) and no further. Etymology I take great pleasure in naming this species after Harald, Barbara, Tomas, Uta, and Aike Schmitz of the Fazenda Rancho Grande in Rondonia, Brazil. Their efforts to preserve rainforest habitat and to en- courage entomological explorations on their ranch not only brought to light this new species but also ser- ves as a shining example of benevolent stewardship of tropical biota.

T. A., 1992. Revision of the genera Euchromius Guenée and Miyakea Marumo (Lepidoptera: Crambidae: Crambinae). — Tijdschrift voor Entomologie 135: 191-274, figs. 1- 198. [issN 0040-7496]. Published 1 December 1992. The Palaearctic, Nearctic, Neotropical, Oriental and Australian species of the genus Euchromius Guenée, 1845 are revised. Euchromius is a senior synonym of Pseudoancylolomia Ahmad, Zaidi & Kamaluddin, 1982. Four new species are described: £. circulus (Burma), £. confusus (Afghanistan, Iran, Tadzhikistan), E. minutus (Brazil) and E. ornatus (India). The fol- lowing synonymies are established: £. pulverosus (Christoph, 1887) is a senior synonym of E. co- chlearellus (Amsel, 1949). Pseudoancylolomia qadrii Ahmad, Zaidi & Kamaluddin, 1982 is a junior synonym of E. ocelleus (Haworth, 1811). E. viette: Bleszynski, 1961 is a senior synonym of E. karsholti Ganev, 1987. The genus Miyakea Marumo, 1933 is revised, M. sinevi sp. n. (Mongolia) is described and M. raddeellus (Caradja, 1910) is reinstated as a valid species. E. lu- shanus Inoue, 1989 is transferred to Miyakea. E. delicatalis (Hampson, 1919) is transferred to the genus Aurotalis Bleszynski, 1970. A key is provided together with full (re)descriptions of all species, with notes on distribution and biology. R. T. A.

The classification of the Pyralidae has been subjec- ted to several changes during the last two decades. In the present paper the genera Euchromius Guenée, 1845 and Miyakea Marumo, 1933 are treated as be- longing to the subfamily Crambinae of the Crambidae, regarding all ‘pyralids’ at superfamily le- vel as proposed by Minet (1982, 1991) and confirm- ed by Solis & Mitter (1992). The taxonomic position of Euchromius and Miyakea has never been the subject of much discus- sion. These taxa have always been placed in the Crambinae. Zeller (1863) subdivided the Crambinae as ‘Crambos’ and ‘Chilones’. Bleszynski (1965) treated Euchromius and Miyakea close to Metaeuchromius Bleszynski, 1960, Pseudargyria Okano, 1962 and Eschata Walker, 1856. Gaskin (1975) redefined the tribus Crambini and erected the subtribus Crambina and Corynophorina with Euchromius included in the subtribus Crambina. Most of these subdivisions within the Crambinae are, however, ill-defined and still little understood. This paper provides the revision of all species of the genera Euchromius and Miyakea are easily recognized within the Crambinae by their yellow medial fascia and the terminal black dots on the forewing. Euchromius has a worldwide distribution with the ex- ception of Indonesia, the Philippines and the islands in the Pacific, while Miyakea is restricted to the east- ern Palaeartic. Most species of Miyakea are known from a few specimens and a few localities only, pro- bably since very few collectors have visited China and surrounding countries. Euchromius and Miyakea are very similar in exter- nal characters. As a consequence, several species of Miyakea have been included erroneously in Euchromius. In this paper a new set of distinguishing characters is given. For more information on the taxonomic history, distribution and biology of the genera I refer to the generic description. MATERIAL AND METHODS In the species descriptions the statement, ‘labial palp two’ stands for: the length of the labial palp is twice the diameter of the eye. The formula for the black terminal dots mentioned in the species descrip- tions is read as follows; 2-2-3-2 stands for: the black terminal dots closest to the apex start with a group of two, followed by a second group of two dots, a group of three dots and finally a group of two dots near the tornus (fig. 7).

The spelling of the localities is taken literally from the la- bels to make tracing of the material easier. For Chinese material the Pinyin transcription is given. Distribution maps are based on personally exam- ined material only, except for Æ. ocelleus, where the North-European localities are mostly based on reli- able literature references. The sequence of the species followed here is based on overall similarity. No phylogenetic conclusions should be drawn from this sequence. The species of Euchromius which were revised and (re)described re- cently (Schouten 1988, 1990) are only briefly treated, but when available, new information has been added. Dissections Dissections and mounting of the genitalia, abdo- mina and tympanal organs were carried out in the way described by Robinson (1976) with some adjust- ments. The abdomen is completely separated from the thorax, taking care not to disrupt the tympanal organs. Then, the abdomen is macerated for three mi- nutes ina KOH 10% solution at 100° Celsius and transferred to ethanol 70% for cleaning. Snipe feath- ers are used to descale the abdomen and micro-pins mounted into a match are used to remove remaining tissue. Genitalia are separated from the abdomen by cutting the posterior membrane of tergite and sterni- te VIII. The aedeagus of the male genitalia is separa- ted from the anellus and treated separately. After staining with Chlorozol Black 1% (diluted in 70% et- hanol), abdomen and genitalia are fixated in 96% et- hanol. Male genitalia are fixated with the valvae spre- ad. Abdomen and genitalia are preserved in Euparal together on one slide, but under separate cover-slips. The abdomen is placed under an elevated cover-slip to avoid accidental flattening of the tympanal organs. Since the Euparal essence will slowly evaporate, a va- cuum underneath the coverslip may occur and air- bubbles can arise, which can be avoided by putting the slide in a stove at 40 °C for three days. The edges of the coverslip are then sealed off with transparent nail-polish. Distortions caused by manipulations during the preparation of the genitalia or by pressure of the coverslip may easily arise. The coverslip can change the orientation of the genitalia to a great extent. The angle in which the valvae, aedeagus or any other part of the genitalia, are bent upward or sideward can be far outside the usual range of variation of the species under consideration. Ignoring these artifacts easily leads to incorrect interpretations, which may be ex- emplified by the synonyms E. siuxellus Ganev & Hacker, 1986 and E. gartheellus Derra, 1985 being a result of a too narrow interpretation of differences ob- served in genital slides (see Hacker 1986, Derra SCHOUTEN: Euchromius and Miyakea 1987). Moreover, the differences observed are for some part caused by distortions.

The taxonomic history at genus level has been thoroughly explained by Bleszynski (1961, 1963) and will not be repeated here. Ahmad, Zaidi & Kamaluddin (1982) erected the new monotypic ge- nus Pseudoancylolomia for the new species qadrii. Pseudoancylolomia gadrii, however, is a junior syno- nym of Euchromius ocelleus (Haworth, 1811) as is pointed out under that species. Pseudoancylolomia can be distinguished from other Crambinae genera (Ahmad et al. 1982) by the well developed proboscis and the anteriorly projecting frons. These characters are, however, represented in all species of Euchromius as well. Vein R5, mentioned as stalked with the partly fused R3-R4, is identical to that of all members of the genus Euchromius (see A ina Met) alE1982 MANE et 2)" Therefore Pseudoancylolomia Ahmad, Zaidi & Kamaluddin, 193 TIJDSCHRIFT VOOR ENTOMOLOGIE, VOLUME 135, 1992 sl Pa d Figs. 7-8.

The firstly described species of the current genus Euchromius is Tinea bella Hübner, 1796. Subsequently, Haworth (1811) described the second species now in Euchromius. Palparia ocellea. Costa (1829), Treitschke (1832), Robinson (1870) and Turati (1924) described species, later to be synonym- ized with ocelleus. Until 1900 Zeller was the main au- thor dealing with species now attributed to Euchromius. He described anapiellus (Zeller, 1847), vinculellus (Zeller, 1847), zonellus (Zeller, 1847) [= ramburiellus (Duponchel, 1836)], superbellus (Zeller, 1849), wockeella (Zeller, 1863) [= superbellus (Zeller, 1849)] and cambridgei (Zeller, 1867). After 1900 mainly three authors were dealing with Euchromius 194 species. Caradja described four species in the period 1910-1937. Amsel described eight species in the peri- od 1949-1961, of which five are now regarded as jun- ior synonyms. Bleszynski in 1960-1967 made a seri- ous effort to revise Euchromius, resulting in the discovery of many synonyms and the description of 13 new species, of which only one turned later to have a older synonym. The Palaearctic species of Euchromius were revised by Bleszynski (1965a), the Neotropical and South- Nearctic ones (in part) by Capps (1966). Study of material in museum collections not seen by previous authors and material collected after the publication of the above mentioned articles, has revealed many new data. Study of material seen by Bleszynski and other authors lead me several times to conclusions conflict- ing with theirs. These conclusions and the new data resulted in the updated revision of the genus Euchromius presented in this paper. The Oriental species are here revised for the first time. The species from the Afrotropical and Australian region were revised by Schouten (1988, 1990), but are included in the key. The present revi- sion deals with 47 species, four of which are new to science. The females of nivalis (Caradja, 1937) and malekalis (Amsel, 1961) are described for the first time. Of two species the female and of three the male is unknown. Additional new species can be expected, especially from Africa, China and the Oriental region since large areas in these regions have never been vis- ited by collectors of Lepidoptera. Diagnosis Dorsal insertion of ductus ejaculatorius is subter- minal; gnathos is, in principle, armed with dorsal thorns; tergite VIII of males with sclerotized pattern; frons always projecting forward; M1 of hindwing lo- cated in the upper angle of the open cell; base of M2 and M3 of hindwing without basal pointing stalk (fig. 1); spinula present (except in nivalis), simple hair- like, without distinctly swollen base (fig. 4). Morphology The morphology is only discussed for features not treated by Schouten (1988). Intraspecific variation The species of Euchromius show little intraspecific variation. Only cambridgei (Zeller, 1867), gratiosellus (Caradja, 1910), ramburiellus (Duponchel, 1836), superbellus (Zeller, 1849) and vinculellus (Zeller, 1847) vary substantially in colouration. Variation in structure of the genitalia is limited as well; some va- riation is known in tanalis Schouten, 1988 and vin- culellus.

The latter is deduced from the sexual dimorphism of Catharia py- renaelis (Dup.) (Pyraloidea: Crambidae: Odontiinae). The male of this diurnal species has normally devel- oped tympanal organs, whereas the female has atro- phic tympanal organs. The dimorphism does not oc- cur in night-flying species which are prone to be attacked by bats. This suggests that the male uses his tympanal organs to locate the female producing sounds by vibrating her wings. Dahm et al. (1971) demonstrated the use of the tympanal organs in the localization of partners in Achrota grisella (Fabricius) (Pyraloidea: Pyralidae: Galleriinae) in combination with the use of pheromones. The diagnostic value at subfamily and family level has been demonstrated by Minet (1982, 1983, 1985, 1991) and Maes (1985). The terminology of the tympanal organs follows Maes (1985). In Euchromius the tympanum and con- junctivum make an angle and the bulla tympani are of the ‘open’ type. Consequently, Euchromius has tympanal organs of the ‘Crambidae’ type, as defined by Minet (1982) and Maes (1985). The tympanal or- gans are located ventrally on the anterior part of the abdomen. Description of the tympanal organs in Euchromius (figs. 3, 4). — The praecinctorium is simple sac-shaped without a thorn-like sclerotization at the connection with the pons tympani. The bulla tympani are bean- shaped. The fornix tympani, supporting the conjunc- tivum, are well developed and clearly visible. The ra- mi tympani are connected, forming a well defined semi-circle, enclosing the sacci tympani. At species level the sacci tympani vary in size and shape. Ventrally the two sacci tympani are connected by a membrane, the conjunctivum saccus tympani. In many cases, the width with which the two sacci tym- pani are connected, in combination with the position of the conjunctivum saccus tympani provide good di- agnostic characters at the species level. The processi tympani vary in size and are largest in ramburiellus, occupying nearly half the breadth of the bulla tympa- ni in that species. The processus tympani is orientat- ed dorsal-ventrally and thus it is not always possible to measure their size. The processus tympani is connected to the tympa- num by the scoloparium and spinula. The scolopar- ium is a chordonotal nerve consisting of four scolo- pale cells (Minet 1983). In mounted specimens, the scoloparium is almost always lost, due to necessary cleaning of the interior of the bulla tympani. The scoloparium is connected to the spinula, a sclerite on the inside of the tympanum. At a magnification of 40 times it usually can be seen as a small point or minute 196 Fig. 10. Venation in Miyakea. line. In Crambinae spinulae have several distinct shapes. The spinula in Euchromius (fig. 4) is a simple hair-like structure, without a distinct swollen base, implantated at an oblique angle on a minute elevation and gradually tapering towards the distal end. The distal end can be clean and thus pointed, or may still have some remains of the scoloparium or tracheal tis- sue connected to it, giving it a frayed tip. To estimate the type of spinula of a genus or species usually many slides should be checked. The spinula must be viewed from several angles before a correct lateral drawing of it can be made. The venula prima, situated lateral to the fornix tympani, is always present. The venula se- cunda, posterior of the fornix tympani, is more or less an extension of the venula prima. In Euchromius the venula secunda is well developed. Distribution The highest numbers of species occur in Africa (19), the Mediterranean (16) and the Near and Middle East (16). Australia has only one single spe- cies, North America two and South America four. No species are found on the islands of South-East Asia. E. subcambridgei has a disjunct distribution in the Sudan, Tunesia and the Cape Verdes. E. ocelleus with an almost cosmopolitic distribution seems to be a mi- gratory species which establishes temporar popula- tions in localities far outside its main distribution area from time to time. Biology E. ocelleus has been mentioned infesting food (Hinton 1943). I am not aware of any recent confir- mation of larvae found in food-products and, there- fore I am sceptical about this claim. The caterpillars of several species have been reared from dead leaves near the base of plants, accidently larvae attack living plants and flower-heads. Transportation of pupae with plant remains seems likely (Meyrick 1895). Dead leaves of mainly Compositae and one species of Dipsacaceae are recorded as foodplants (Millière 1868). Euchromius species are found in various habitats, but most of them prefer dry and warm areas; no spe- cies really enters the tropical rain forest. E. gnathosel- lus and zephyrus have only been found in plantations mixed with remains of secondary forest in West- Africa, once covered with lowland tropical rain forest. Several species are restricted to mountain areas and plateaus e.g. tanalis and hampsoni in Africa, nivalis in China and saltalis in South America. Many species are found from sea-level up to more than 1000 m alti- tude. £. ocelleus is recorded from the highest altitude, 4200 m (Afghanistan). Excluded species E. brunnealis (Hampson, 1919), micralis (Hampson, 1919) and pygmea (Hering, 1903) do not belong to the genus Euchromius in the present sense. They should be classified in a separate genus to be de- scribed in a forthcoming paper (Schouten, in prep.). E. delicatalis (Hampson, 1919) is transferred to Aurotalis Bleszynski, a genus not closely related to Euchromius. Bleszynski (1970) regards Aurotalis a close relative of Conotalis Hampson, 1919. The fore- wing of E. delicatalis (fig. 2) has the Sc partly fused with R1, whereas R2 is fused with R3+R4, a feature never encountered in Euchromius (fig. 1). The male genitalia of delicatalis lack any processus on the val- vae, which are broad and of the same type as in Aurotalis. E. kuphitincta (Lucas, 1898) was transferred from Diptychophora to Euchromius by Gaskin (1975a) . The type material of this species has not been located (Gaskin 1975a). The original description (Lucas 1898: 80), however, leaves no doubt that the species is not a member of Euchromius. Several dentate lines in the forewing are mentioned and the base of the hindwing is said to have up to six or seven fine violet fuscous transverse lines. Both features have never been found in Euchromius. Especially the description of the hindwing suggests attribution of this species to the Diptychorini or the Pyraustinae. As long as the holotype has not been located it will be impossible to classify this species with certainty. SCHOUTEN: Euchromius and Miyakea Checklist of extant Euchromius Guenée ZE 18. 39: 40.

Diagnosis. — Externally difficult to separate from species with a double fascia and frons with one clear point. Differs from £. ocelleus, E. galapagosalis, E. sal- talis, E. minutus, E. limaellus, E. mythus and E. tanal- is in male genitalia by the basal projections on the gnathos, from £. cornus in lacking the projections of the juxta. E. californicalis can be distinguished in fe- male genitalia by a mushroom-shaped ostium in com- bination with signa unequal in size and a drop-shaped sclerotization in the membrane of tergite VIII. External characters male, female (fig. 15). — Wingspan 20-24 mm. Frons sharply produced for- ward into clear point, creamy white to light brown, no ventral ridge; vertex creamy white; labial palp two and a half to three, sides white at base, becoming creamy white to light brown, creamy white from above and below; maxillary palp white to creamy white, brown ringed at base of last segment; antenna creamy white, from about the middle very inconspic- uous darkly ringed. Thorax creamy white; patagia creamy white; tegulae creamy white evenly mottled, sometimes with dark patch in the middle. Forewing, groundcolour white, densely suffused with ochreous to dark brown scales; medial fascia double, gently arched to nearly straight, running to one-fifth to one- sixth of the dorsum; subterminal line ochreous brown, inconspicuous, closer to termination of poste- rior area than to terminal dots; area adjacent to termi- nal dots broad, white; nine or eight black terminal dots, formula 2-2-3-2 or 2-2-3-1; fringes shiny creamy white with two or three brown lines. Hindwing creamy white to brown-grey, subterminal fascia present or not, termen darkly bordered; fringes white with brownish line. Tergite VIII (fig. 16). — Sclerite normally sclero- tized, posterior part rectangular, stalk broad ending abruptly, anterior pattern invisible. Male genitalia (fig. 100). — Uncus slightly bent, with thin dorsal crest; gnathos longer, two dorsal-ba- sal projections, two dorsal thorns, terminal part long; tegumen without appendix angularis; sacculus nor- mal, processus of sacculus absent, processus basalis small, two processi inferiores valvae; cucullus bent upward, with strong basal fold forming clear lob-like projection; juxta small, triangular; vinculum long; ae- deagus long, slender with three groups of cornuti, sometimes only two clearly visible. Female genitalia (fig. 152). — Papillae anales small; membrane of tergite VIII with inconspicuous drop- shaped sclerotization, edges of tergite VIII grooved, not connected; ostium mushroom-shaped, not clear, 203 TIJDSCHRIFT VOOR ENTOMOLOGIE, VOLUME 135, 1992 roughly granulate; ductus bursae long, more strongly sclerotized in upper part; ductus seminalis narrow; bursa copulatrix oblong, with two long signa, un- equal in size. Biology. — Unknown. Specimens caught from March to September, with peaks in June, July and August. Recorded from 300 m up to 2500 m altitude. Distribution (fig. 17). — A West-Neartic distribu- tion. Canada: British Columbia and Alberta. USA: Washington, Idaho, Montana, North Dakota, Oregon, Wyoming, California, Nevada, Utha, Colorado, Nebraska and New Mexico. Remarks. — The lectotype specimen in Mczc bears only the label “Type 14297’. A second specimen with- out any label is presumably a paralectotype. The third specimen can almost certainly be excluded from the syntype series since it has not been collected by Edwards (Miller & Hodges 1990). The label reads: C.H.F. March 95 Cal Behr 17, indicating that the specimen was caught in March 1895 which is after the date of publication of californicalis. The female genitalia figured by Corbet and Tams (1943: 72, figs. 125 and 162) do not belong to £. californicalis. 5.

Differs in female genitalia in having a small mushroom or lipshaped ostium in combination with the edges of tergite VIII separate and smooth and signa of equal length. Biology. — E. ocelleus has been found in various habitats, viz. cultivated areas, macchia in the Mediterranean, dry savanna in Africa, salt-steppe in the Middle East and salt-areas in North-America. It lives from sea leavel up to high altitudes, viz. up to 3100 m in the La Sal Mountains in Utah, at 1700 m in the Greater Atlas, at 2600 m in Iran and 4200 m in Afghanistan and at 2300 m in the north-eastern part of Burma. The larvae has been described by Hinton (1943: 202) from a single larva. It is said to be found on stored food-products and owes it wide distribution to human transportation with these products. Since Hinton only had a single larva, it is not certain that it was E. ocelleus, or it may be have been accidental that it was found associated with stored food-products. I agree with Hinton on the assumption that the wide distribution of E. ocelleus is, at least partly, very likely caused by human transportation. Lhomme (1935- 1946) gives dead and decaying leaves, etc. as the food- source, Capps (1966) states that the larvae live on the roots of corn and Milo maize (Sorghum). It seem very plausible that ocelleus, as larvae or pupae, is transport- ed with remains of plants and is not to be regarded as a pest. It is also certainly migratory since several spec- imens have been caught at sea as far as 50 miles out of the coast.

Remarks. — Ahmad et al. (1982: 15) published the new species and genus Pseudoancylolomia qadrii. Together with the description they figure the male genitalia and wing-venation. Since Ahmad et al. were clearly unaware of the existence of the genus Euchromius and all the species belonging to it, they make no reference as how to distinguish P. gadrii from Euchromius ssp. The characters in which gadrii differs from other species are therefore to be found under the genus description. Arguments to synonym- ize the genus Pseudoancylolomia with Euchromius have been summarized before, while P. gadrii is evidently a synonym of E. ocelleus (Haworth, 1811). 16.

Remarks. — There has been much confusion about the identity of this species. E. pulverosus (Christoph, 1887) was originally described from female material only. Amsel (1949: 234) mentioned a male which he found somewhat different from Æ. pulverosus, which he conditionally named ‘cochlearella. Bleszynski & Collins (1962: 305) first used the name Euchromius cochlearellus (Amsel, 1949). Bleszynski (1965a) re- corded five male specimens not conspecific with the male of £. cochlearellus (Amsel, 1949), which he re- garded the male of E. pulverosus. He also found two females, difficult to separate from the females of E. pulverosus, which he regarded the females of Æ cochlearellus. It appeared, however, that the males and females of the two species had been mixed up by Bleszynski. Due to the rearranging of the males and females, £. cochlearellus has become a junior synonym of E. pul- verosus, leaving the other species without a name. The name for the latter is Euchromius confusus. 17. Euchromius confusus sp. n. (figs. 34-36, 113, 164) Euchromius cochlearellus auct., nec Amsel [misidentifica- tion].

Diagnosis. — Differs from all other species by its straight single medial fascia in combination with six or seven black terminal dots and having a yellow area adjacent to the black terminal dots. Biology. — Largely unknown. Flight-periods can be split into three parts. Firstly south of the Mediterranean Sea (Morocco, Algeria and Tunisia), where this species has two generations and was caught from March to September, with peaks in May-June and August-September. Secondly the area north of the Mediterranean Sea (Spain, France and Italy), where there are two more or less continuous genera- tions from April to October with peaks in May and August-September. Thirdly, east of the Mediterranean where specimens have been caught all year round, with peaks in March-April-May and September-October. Highest recorded altitude 1400 m in Morocco. Distribution (fig. 37). — Spain, France, Italy, Cyprus, Turkey, Georgia, Afghanistan, Iran, Oman, Saudi Arabia, Jordan, Israel, Yemen Arabic Republic, Kenya, Niger, Tunisia, Algeria and Morocco. Remarks. — Bleszynski (1965a: 81) and Schouten (1988: 26) incorrectly state the male with GS 628 Bl. as the lectotype; this should read ‘neotype’. 19.

Diagnosis. — Similar to E. bellus, but can be distin- guished by the narrow yellow area adjacent to termi- nal dots, which is broad and white in £. bellus. The male of E. anapiellus differs from E. bellus in having a cornutus which is curved less than 180° (figs. 122, 123). Differs in female genitalia from £. bellus in hav- ing the sclerotization in ostium two times as long as broad, three times as long as broad in E. bellus (figs. IA) External characters male, female (fig. 38). — Wingspan 13-17 mm. Frons produced forward, with point, creamy white, no ventral ridge; vertex creamy white; labial palp two, sides white at base, becoming brown, creamy white from above and below; maxil- lary palp creamy white, brown ringed at base of last segment, terminal part creamy white; antenna creamy white to light grey, from about the middle inconspic- uous darkly ringed. Thorax creamy white; patagia creamy white with two broad longitudinal light brown stripes; tegulae creamy white with dark patch in the middle. Forewing, groundcolour white densely suffused with ochreous to dark brown scales; medial fascia double, inner one usually reduced, outer fascia straight, running to one-third of the dorsum; subter- minal line ochreous to dark brown, about midway between terminal dots and termination of posterior area; area adjacent to terminal dots narrow, yellow; nine or eight black terminal dots, formula 2-2-3-2 or 2-2-3-1; fringes shiny, evenly grey-brown. Hindwing light brown to dark grey, subterminal fascia present, termen darkly bordered; fringes creamy white with brownish line. Tergite VIII (fig. 39). — Sclerite normally sclero- tized, posterior part slightly larger than anterior part, stalk stout. Male genitalia (fig. 122). — Uncus normal, tapering to sharp pointed tip; gnathos longer, with two dorsal thorns, terminal part long; tegumen without appen- dix angularis; sacculus swollen, swollen, partly armed with thin elongated crest, processus of sacculus short, blunt, dorsal processus of sacculus pointed, processus basalis broad at base, tapering soon, bent inward, ven- SCHOUTEN: Euchromius and Miyakea tral terminal part minutely dentate, processus inferior valvae at base of processus basalis, small, cucullus broad, slightly bent upward at tip; juxta broad trian- gular; vinculum rectangular; aedeagus small, one large pointed cornutus. Female genitalia (fig. 171). — Papillae anales nor- mal; membrane of tergite VIII without clear sclerot- izations; edges of tergite VIII not connected; ostium simple, somewhat pointed, sclerotization two times as long as broad, ductus bursae posterior part broad; ductus seminalis narrow; bursa copulatrix elongated, signa absent. Biology. — Unknown. Flies after sunset (Zeller 1847). One generation, the first specimens were caught in the first half of May. It continues through June, July, August to the end of September. Distribution (fig. 40). — A West-Mediterranean species, occurring in Spain, France, Italy, Tunisia, Algeria and Morocco. Remarks. — Roesler (1983: 12) records Sardinia. Records from Portugal (Mendes D’Azevedo 1904- 1905: 226, Vieilledent 1905: 201, Zerkowitz 1946: 145) and Egypt and Asia Minor (Bleszynski 1965a: 69) seem to be based on misidentified material.

Biology. — The single generation flies from May up to the end of August. The flight reaches its peak in July. In Israel a specimen has been caught on the 30th of March. In Italy £. bellus has been caught up to 1400 m, in Turkey up to 2200 m and in Iran up to 2000 m. Hogenes (pers. comm.) caught the moths in Italy at very hot and dry localities, with scarce herbal vegetation with very few grasses. The larva is men- tioned to live on dry leaves of Picris and Scabiosa, also recorded to attack the roots and flower heads (Milliere 1868: 219). 215 TIJDSCHRIFT VOOR ENTOMOLOGIE, VOLUME 135, 1992 Distribution (fig. 43). — This species is one of the commonest of the genus. It occurs in Spain, France, Italy, Yugoslavia, Hungary, Rumania, Bulgaria, Greece, Turkey, Russia, Ukraine (Krim), Georgia, Tadzhikistan, Iraq, Iran, Syria, Jordan, Lebanon, Israel and Morocco. Bleszynski (1965A: 69) also records Czechoslovakia. Remarks. — Butler (1882: 42) mentions £. bellus from Honolulu. This reference refers to Æ ocelleus. 21.

Diagnosis. — Difficult to distinguish externally from other species with a single medial fascia. Differs in male genitalia in having the processus of sacculus forming a heavily spined lobe in combination with the processus basalis broad at base, narrowing very abruptly. Differs in female genitalia in a roundish bursa copulatrix with one round signum in combina- tion with edges of tergite VIII connected forming a minute projection and having the lamella postvagin- alis rectangular. Biology. — Unknown. Specimens caught in February, November and December in Saudi Arabia and Oman, in August in Chad. Distribution (fig. 93). — Occurs in the Saudian Peninsula and the Tibesti Mountains of Chad. Remarks. — Ganev (1987: 44) describes the species Euchromius karsholti based on a single female from Saudi Arabia. In the diagnosis he gives no distinct dif- ferences between E. viettei Bleszynski, 1961 and kars- holti. He only states: “VIII. tergite very complicated, however differing from those of Euchromius hampso- niand Euchromius viette?. The quality of the drawing of the female genitalia is too poor to make any state- ment on the degree of difference between the species concerned. Study of the holotypes proved no differ- ences between E. karsholti Ganev, 1987 and E. viettei Bleszynski, 1961. E. karsholti Ganev, 1987 is there- fore a junior synonym of E. viettei Bleszynski, 1961. 40. Euchromius hampsoni (Rothschild, 1921) (figs. 143, 191) Ommatopteryx hampsoni Rothschild, 1921: 220.

Landry collected the first specimen for West Africa in Burkina Faso: Kompienbiga, 15 km W. of Pama, 5-13.VIII.1988 (LAND). Remark. — Due to an incorrectly positioned female genitalia the ductus seminalis was wrongly interpret- ed and recorded as narrow (Schouten 1988). In con- trast to this the ductus seminalis starts broad and nar- rows soon, the sclerotized ring starts in the broad part of the ductus seminalis. 42.

The genus Miyakea was described by Marumo in 1933 to accommodate Eromene expansa Butler, 1810. Caradja (1910) described a new form of Eromene bel- 234 la (= Euchromius bellus) from Russia: Radde and named it raddeellus. Bleszynski & Collins (1962) made it a synonym of M. expansa (Butler, 1881). The third species has only recently been described from Taiwan: Euchromius lushanus Inoue, 1989. It is now transferred to Miyakea. The female genitalia of M. ex- pansa are depicted and described for the first time. M. sinevi sp. n. is described from Mongolia. Diagnosis of Miyakea Ductus ejaculatorius enters the aedeagus terminal- ly; dorsal thorns on the gnathos absent; tergite VIII without sclerotized pattern; frons projecting or not; M1 of hindwing located in the lower part of the mo- re or less closed cell; base of M2 and M3 of hindwing with a basal pointing vein, more or less closing the cell (fig. 10); spinula not visible. Morphology Head. The frons has no diagnostic characters at species level, it is projection or not, without point, creamy white to brown without a ventral ridge. The relative size of the labial palp compared to the eye dia- meter can be used to separate the species. The anten- na are serrate in males and setaceous in females. The scales on the antenna are creamy white, sometimes inconspicuous darkly ringed. Thorax. Thorax uniformly coloured, creamy white to brown. Patagia light brown to brown. Tegulae creamy white with a dark patch in the middle. Venation (fig. 10). Very similar to that of the genus Euchromius. The differences with the latter genus are listed under ‘Diagnosis’. Wing pattern. The ground-plan of the pattern is similar to that of Euchromius (fig. 7), but there are no species with a single medial fascia. The formula of the black terminal dots usually offers a good character to distinguish the species. The position of the double medial at the costa is in some cases diagnostic. Genitalia. The male genitalia offer excellent diag- nostic characters. The uncus is rather uniform, slen- der and tapering to a sharply pointed tip. The gna- thos is of equal length, the tip is minutely dentate. The sacculus is reduced to absent. The processus bas- alis is reduced to very prominent. The costal edge of the valvae forming a prominent projection or not, the cucullus is truncate. Processus inferior valvae incon- spicuous to absent. Juxta small, rounded. Vinculum long. Aedeagus highly diagnostic, usually with cornu- ti. Female genitalia, papillae anales uniformly small. Ostium armed with variously shaped projections. Ductus bursae short, with or without a pouch-like enlargement under the ostium. Ductus seminalis al- ways narrow. Bursa copulatrix oblong without signa. Intraspecific variation The intraspecific variation of Miyakea is limited, the male genitalia in raddeellus show some variation. Tympanal organs In Miyakea the tympanal organs are similar to those of Euchromius, but the spinula on the tympa- num is not sclerotized. Distribution The four species are confined to Asia, China, Taiwan and Japan. M. expansa is endemic to Japan, lushanus is endemic to Taiwan. M. sinevi has been found in Mongolia. M. raddeellus has the most exten- sive distribution, occurring in China, Russia and Korea. Biology Unknown. Raddeellus has been caught at an altitu- de of 1800 m.

Hindwing grey-brown, subterminal fascia present, termen darkly bordered; fringes creamy white. Male genitalia (fig. 118). — Uncus normal; gnathos equal in length tip minutely dentate, dorsal thorns absent; tegumen slender, appendix angularis absent; sacculus inconspicuous, processus of sacculus absent, processus basalis reduced to elongated rim, processus inferior valvae absent, cucullus slightly concave, blunt; juxta roundish; vinculum elongated; aedeagus curved, no cornuti. Female genitalia (fig. 169). — Papillae anales small; membrane of tergite VIII without sclerotizations; os- tium small with very small low projecting tooth; duc- tus bursae short with more sclerotized lines; ductus seminalis narrow; bursa copulatrix oblong, signum absent. Biology. — Unknown. Specimens were caught in July and August at 1200 m altitude. Distribution (fig. 95). — Taiwan. Remarks. — M. lushanus is the sister species of rad- deellus and/or expansa judging to the male genitalia and falls within the genus diagnosis of the genus Miyakea. Leaving this species in Euchromius would cause a polyphyletic genus. Therefore /ushanus is transferred to Miyakea Marumo, 1933. In the original description slide number 13230 is given as belonging to the holotype, but upon check- ing the type material this turns out to be the female paratype slide number. The holotype slide number is 13229. 2. Miyakea raddeellus (Caradja, 1910) sp. rev. (hies..9,.95, 96, 1191202167) Eromene bellus form raddeella Caradja, 1910: 115.

Published 1 December 1992. The eight Palaearctic and Oriental species of the genus Peltodytes Régimbart are revised. P. pek- inensis is described as new. Most primary types have been studied. P. wui Gschwendtner is con- sidered a junior synonym of P. coomani Peschet. Lectotypes are designated for P. coomani Peschet, P. intermedius (Sharp), P. variabilis (Clark) and P. wui Gschwendtner. A key to the species is provided, as are distribution-maps. B. J. van Vondel, Roestuin 78, 3343 CV Hendrik Ido Ambacht, The Netherlands. Key words. — Peltodytes, palaearctic region, oriental region, new species. Since Zimmermann (1924) published his key to the Haliplidae of the world, only little attention has been payed to the East Palaearctic and Oriental spe- cies of Peltodytes, with only four new species described since. Doubts about the status of these species war- ranted a revision. The type material of most nominal taxa was studied, but the identity of some others was sufficiently established. Unfortunately a few types could not be located. Female genitalia are not described, because they usually appear very uniform. Further research is nec- essary to check if there are characters sufficiently reli- able to separate the species. MATERIAL About 1700 specimens, including type-material were studied from the following collections: British Museum (Natural History), London, UK (BMNH); B.P. Bishop Museum, Honolulu, Hawaii, USA (BpBM); Fries Natuurhistorisch Museum, Leeuwarden, Netherlands (FnML); IES Laboratory, Hebrew University of Jerusalem, Israel (Hui); Institut Royal des Sciences Naturelles, Brussels, Belgium (tsNB); Museum National d'Histoire Naturelle, Paris, France (MNHN); Museon, The Hague, Netherlands (Mog); Naturhistorisches Museum Wien, Vienna, Austria (NHMV); Natuurmu- seum Rotterdam, Rotterdam, Netherlands (NHMz); Oberösterreichisches Landesmuseum, Linz, Austria (OLML); Instituut voor Bos- en Natuuronderzoek (Rijksinstituut voor Natuurbeheer), Leersum, Netherlands (RIN); Nationaal Natuurhistorisch Museum (Rijks Museum van Natuurlijke Historie), Leiden, Netherlands (RMNH); Instituut voor Taxo- nomische Zoölogie (Zoologisch Museum), Amster- dam, Netherlands (ZMAN); Zoologiska Museet, Helsinki, Finland (ZMH); Museum für Naturkunde der Humboldt-Universität, Berlin, Germany (zMHB); Universitetets Zoologiske Museum, Copenhagen, Denmark (zmuc); Zoologische Staatssammlung, Munich, Germany (zsmc). private collections: A.

Morphological terms are exemplified in figs. 1 and 2. The Palaearctic and Oriental regions are treated here together because some species are common to both regions. Peltodytes is not known from the Australasian region east of Sulawesi. Locality-names are spelled, as far as possible, ac- cording to the Times Atlas of the World (Comprehensive edition, 1983), but when different from original labels, the modern name is given in pa- rentheses. Names of countries are used with their present-day boundaries. 25) TIJDSCHRIFT VOOR ENTOMOLOGIE, VOLUME 135, 1992 ON === DD UD D WNT” VE BWN: Fig. 1.

SYSTEMATIC SECTION Genus Peltodytes Régimbart Peltodytes Régimbart, 1878: 450. Type-species: Dytiscus cae- sus Duftschmid, 1805, by subsequent designation (Balfour-Browne 1936: 68). Cnemidotus sensu Erichson, 1832: 48 (nec Cnemidotus Illiger, 1802: 373). [Type-species not validly fixed (Holmen, 1987: 86)]. Neopeltodytes Satô, 1963a: 21. Type-species: Peltodytes callo- sus (Leconte), by original designation [see note below]. Cnemidotus, Aubé 1836: 36, Seidlitz 1887: 35.

Remarks Satö referred to the division of Peltodytes into two groups by Zimmermann (1924) and defined the sub- genus Neopeltodytes by the absence of the posterior teeth on the metacoxal plates as present in the species of Peltodytes s. str. Zimmermann used another char- acter: an in the middle impressed metasternal process in group I (= Peltodytes s. str. in Palaearctic, Ethiopean and Oriental regions) or a not impressed metasternal process in group II (=Neopeltodytes, in Nearctic and most northern part of Neotropical regions). Assignment of Peltodytes-specimens to one of the subgenera meets some problems as there are Nearctic species having a weak tooth on the metacoxal plates or a more or less impressed metasternal process, while some Palaearctic species sometimes show hardly de- veloped teeth on the metacoxal plates. À more exten- sive character-set is needed to support the subgeneric division. The phylogenetic position of Peltodytes is discussed by Beutel & Ruhnau (1990). The genus Peltodytes is represented in all faunal re- gions, excepting the Australasian and the Neotropical regions apart from Mexico and Cuba (Roberts 1913, Zimmermann 1924, Guignot 1959). Differential diagnosis The genus Peltodytes is defined by the following combination of characters: Head: Labial and maxillar palpi with ultimate seg- ment clearly longer than penultimate segment. Behind the eyes only one genal line (fig. 51). Elytra: along suture a stria over at least posterior half. All puncture-rows relatively equal in strength, no weaker secondary puncture-rows present. If inter- mediate (secondary?) puncture-rows are present, these are restricted to apical part and about as strong as adjacent rows. Apical part of suture incised, expos- ing inner margin of suture. Underside: Epipleura reaching last abdominal seg- ment. Metacoxal plates reaching at least sixth sternite, laterally bordered to halfway posterior edge. Posterior edge of each plate produced into a strong tooth, ex- cept or hardly in nearctic species. The wings were figured by Griffini (1897). Sexual characters: Males have the first two tarsal segments of fore and midlegs widened and ventrally provided with sucker-hairs. Within the Haliplidae Peltodytes can be recognized by means of the following key. 7 to the genera of Haliplidae: Last segment of palpi longer than penultimate segment (fig. 6 and 7).

Peltodytes caesus ssp. levantinus, Guéorguiev 1958: 44. Remarks P. caesus was described from Austria. Since no ot- her species of Peltodytes are known from Austria, the description by Duftschmid leaves hardly any doubt about the identity of the species. Schönherr (1808: 26) gives Dytiscus curculinus O. F. Miiller as a synonym of D. impressus Fabricius, which is not conspecific with P. caesus. Zimmermann (1920) gives it again (with a questionmark) as a pos- sible synonym of P. caesus. As Müllers’ collection does not exist anymore it seems impossible to settle the identity of this name. Description Length 3.3-3.8 mm, width 1.7-2.0 mm. Body sub- parallel to parallel, widest in the middle (fig. 3). Head: Yellow to brown, two large, sometimes vague, dark blotches between eyes, sometimes conflu- ent with slight darkening on vertex. Moderately strongly and densely punctured, punctures on vertex darkened. Distance between eyes 0.9-1.0X width of one eye. Antennae yellow to yellow-red, segment 4-6 about as long as wide (fig. 4).

Remarks Aube’s original description of rotundatus, in which the specific character of the sharp tooth on the meta- coxal plate is mentioned, leaves no doubt about the identity of this species. The species or subspecies or variety conifer differs from rotundatus in having weaker elytral punctures and a less interrupted fourth elytral puncture-row. These characters, however, are very variable and all kind of intermediate forms may be met with. Description Length 3.3-3.9 mm, width 2.0-2.2 mm.

New data on the systematics of Greek species of Poecilimon Fischer, 1853 are presented. Three new species are described: P. gracilioides (from Ipiros), P. mariannae (from Thessalia) and P. er- imanthos (from the Peloponnisos). P. artedentatus Heller, P. veluchianus Ramme and P. zimme- ri Ramme are given species rank. P. mytilenensis Werner is redescribed and additional descrip- tive notes are provided for P. soulion L. Willemse, P. aegaeus Werner and P. athos Tilmans et al. New data on bioacoustics, ecology and faunistics for some species are recorded as well. An up- dated check list of Greek species is included. Correspondence. — Dr. F. Willemse, Laurastraat 67, 6471 JH Eygelshoven, The Netherlands. Key words. — Orthoptera, Phaneropterinae, Poecilimon, taxonomy, bioacoustics, Greece. The genus of Poecilimon Fischer, 1853 includes over one hundred species, spread over southeast Europe and adjacent Asia. All are short winged, usu- ally green coloured, living in forests, shrubby vegeta- tion or open habitats from sea-level to above the tim- berline. Some species are widespread, but most have restricted and some even remarkably small ranges. Systematics of Poecilimon are difficult due to the large number of closely similar species. Up to 1984 system- atic studies were based entirely on morphology (Ramme 1933, Bey-Bienko 1954, Harz 1969, Willemse 1982, 1984). As in most bush-crickets, males of Poecilimon pro- duce calling songs which, in presenting an excellent means of recognizing, provide the basis for a mate se- lection system. Heller (1984) was the first to present results of an elaborate study on song and morphology of stridulatory file in Poecilimon. Both constitute helpful distinctive characters (e. g. file in P. ornatuslaffinis, song in chopardil veluchia- nus). Using these two characters Heller (1984) con- cluded that a number of previously recognized species or groups of species are allied either markedly more or less than formerly presumed. As a result a number of taxonomic adjustments, mainly synonymic, were proposed. Renewed studies (Willemse 1985a, Heller 1988, 1990) of some of the species-groups, including morphological characters and based on more materi- al, proved that some of these taxonomic readjust- ments were premature. The present paper is a further contribution towards the systematics of Poecilimon, partly based on bioacoustics, with the description of three new species. As far as the systematics of Greek species of Poecilimon concern the three main prob- lems remaining are the taxonomic ranking of the spe- cies groups of elegans - brunneri - macedonicus, jonicus - tessellatus - superbus, ampliatus - ebneri - klisuriensis and the heterogeneous affinis complex. Besides new species can still be expected especially in the compar- atively less well explored Aegean islands. A side effect of recent research is a considerable amount of new faunistic data since its account in Willemse (1984, 1985a). Some new information may be found in Ingrisch & Pavicevic (1985) (e. g. P. schmidti), Ponel & Hebrard (1988), Heller (1988) and in this paper. But there is considerably more and the senior author is preparing a communication on important new faunistic data of Greek Orthoptera in- cluding also Poecilimon. For convenience an updated checklist of Greek Poecilimon taxa is included.

Song recording and analysis. — For recordings of the song the following equipment has been used: Uher 4200 Report Monitor with AKG D 202 E micro- phone with low frequencies off (after modification) (P. gracilioides); Uher 4200 1c with Uher M 645 mi- crophone (recordings of other species). To improve quality recordings were made indoors. Oscillograms were made by using a personal computer and the pro- gram TURBOLAB (Stemmer AG). Wing movements were registrated by an opto-electronic device (Heller 1988). Full data of the recordings can be obtained from the authors. Stridulatory files were studied with a light microscope and a Scanning Electron Mi- croscope (SEM) (Institut für Zoologie I, Universität Erlangen). A batdetector (QMC-mini) was used in the field to locate males as indicated in the text. Song terminology. — Calling song: the song pro- duced by an isolated male. Impulse: the sound pro- duced by the contact of one file tooth with the scrap- er (= plectrum). Syllable: the sound produced by one complete up (opening) and down (closing)stroke of the fore wing. Hemisyllable: the sound produced by one unidirectional movement (opening or closing) of the fore wings. Echeme: a first-order assemblage of syllables. Echeme-sequence: a first order assemblage of echemes. Presentation. — In the checklist species are present- ed in alphabetical order but the sequence of the spe- cies in the present study follows a preliminary ar- rangement of relationships based on the song pattern (Heller 1990). References listed under the species are not always complete, full bibliography up to 1985 may be found in Willemse (1982, 1984, 1985a). Material listed is new and does not include previous- ly recorded specimens except for the type material of P. aegaeus. Measurements are given in mm and con- cern the length. Transliteration of Greek orthography in Roman characters agrees with the system proposed by the Permanent Committee on Geographical Names for British Official Use, London.

Considering the consistency and degree of difference and in order to balance the taxonomic interpretation assigned to them with the taxonomic interpretation given to similar differences observed in Poecilimon it has been decided to raise artedentatus to species level. It is noted here that a confusing mistake has slipped into the key in Willemse (1985b: 38-39). The charac- ters of the stridulatory file were exchanged erroneous- ly and should read: 118(117)Stridulatory file with relative distance between the teeth larger, the total number of teeth less (some 120); etc. … EN Poecilimon obesus Brunner 1878 Stridulatory file with relative distance between the teeth smaller, the total number ohteethlaren(some 280); etc... ns Poecilimon artedentatus Heller, 1984 Poecilimon soulion L.

Bioacoustics. — Male calling song an isolated syl- lable (fig. 30), produced with intervals of several sec- onds. Two syllables produced immediately one after another occur only sporadically. Syllable composed of three impulse groups: a series of up to 50 faint im- pulses, slightly increasing in amplitude, followed by a second group of about 7 loud impulses separated from each other by intervals of 10 to 20 ms and the fi- nal group consisting of about 20 loud impulses with intervals less than 3 ms (30°C). Fore wing move- ments not yet registrated. Distribution and ecology Known only from Mt. Tzoumerka (1400-1800 m altitude), NE of the town of Arta, Ipiros, western continental Greece. Tzoumerka is the archaic name for Mt. Athamanon or Athamanika. This large mountain complex, highest summit 2393 m, is zoogeographically somewhat isolated being quite nar- rowly connected eastward with the Pindhos range and separated westward by the Arakhthos river from some lower mountains in western Ipiros. The new species was found at 1400-1800 m altitude on the northeastern slopes of one of the southern summits, named Spilia (1932 m), S of the village of Theodhoriana. The habitat, close to a spring, are roc- ky slopes covered by rich vegetation of low shrubs, herbs and grasses. The species occurs quite locally, was not numerous and found mainly on Helleborus leaves, together with P. ornatus, jonicus lobulatus, zimmeri and veluchtanus. Differential diagnosis The species is defined by pronotum, fore wing and cercus in the male, basal fold of the lower ovipositor valve in the female and size, slender habitus, colora- tion and almost unarmed hind femora in both sexes. A key character is presented by the stridulatory file. P. gracilioides resembles P. gracilis in size, colora- tion and general habitus but differs from it by less raised male pronotum (figs. 23-24), shorter male cer- cus (figs. 12-13) and especially in the male stridulato- ry file: in gracilis (L. Willemse 1987, Heller 1988) the teeth are gradually narrowing and closer set near the transition of mid to distal third of file length, in gra- cilioides size and spacing of teeth changes abruptly at that part of the file (figs. 3-4). The calling song resem- bles that of P. gracilis (Heller 1984, 1988) but the dis- tinction is not yet pointed out because variability and influence of temperature are known insufficiently. Readily recognizable differences with P. soulion (L. Willemse 1987, Heller 1988) refer to a more robust habitus, broader and less raised male pronotum, larg- er size, more spined hind femora, slightly deeper basal groove of the lower ovipositor valve and the colora- WILLEMSE & HELLER: Systematics of Greek Poecilimon tion in this species. The male cercus of both species differs only slightly (figs. 11-12). The sudden change in spacing of the teeth of the stridulatory file is shared by both species. In P. soulion the file is longer (3.0-3.2 mm against 2.7-2.9 mm), the number of teeth in its proximal two thirds slightly larger (58-62 against 38- 45) and the difference in spacing of the teeth in the mid part of the file compared with those at its proxi- mal (= basal) end apparently larger: about 36 and 18 per mm against about 23 and 21 teeth per mm in gra- cilioides. Bioacoustics can not be compared as those of P. soulion are unknown. Etymology Named after its resemblance to P. gracilis.

Additional descriptive notes Auditory spiracle large, aperture elliptical, exten- ding dorsally to upper third of pronotal lateral lobe. Female stridulatory apparatus: ventral side of left elyt- ron provided with plectrum; stridulatory pegs on dor- sal surface of small veinlets (most of them almost pa- rallel to each other) of postero-apical part of right elytron. Bioacoustics. — Male calling song ( fig. 31) an iso- lated syllable, produced with intervals of about 1 s (ca. 29°C); syllable composed of two hemisyllables, closing one distinctly louder than opening one; open- ing hemisyllable (45 ms at ca. 29°C) about 25 im- pulses; closing hemisyllable (70 ms at ca. 29°C) com- monly two groups of impulses separated by interval of about 25 ms (ca. 29°C), first group of 20-40 impuls- es, second group of 1-8 or sometimes missing; maxi- mum of frequency spectrum 29-44 kHz. Distribution The range, previously poorly known (Willemse 1984: map 19), is remarkably small, restricted to coastal areas of extreme southwestern continental Greece and opposite part of the north-western Peloponnisos (fig. 42).

Bioacoustics. — Male calling song (figs. 32-33) an isolated syllable (fig. 32) or a short echeme (fig. 33) repeated at variable intervals (often about 1 s; 23- 24°C); isolated syllable consisting of very soft open- ing hemisyllable (sometimes even undetectable) and loud and very short (up to 5 ms; 23-24°C) closing hemisyllable. An echeme begins with a syllable similar to isolated one followed by a group of 10-15 impuls- es (about 50 ms; 23-24°C), produced during second opening of elytra while final closing movement pro- duces no sound at all. Echemes possibly produced mainly by males which do receive response of a fe- 308 male. Distribution and ecology The range of the species covers a remarkably small area of the northwestern Peloponnisos: from the wes- tern and southern slopes of Mt. Erimanthos (up to 1100 m altitude) down to the adjacent lowlands of northern Ilia (fig. 42). The species was found on thistles, blackberry bushes and Astragalus, sometimes in a marshy spot. P. erimanthos occurred syntopically with werneri (Akhaia/Ilia: Porte), laevissimus (Akhaia: Kalentzi; Ilia: Koumanis), zimmeri (Ilia: Mt.Lambia) and nobilis (Ilia: Koumanis). Attempts to find the species together with P. jonicus tessellatus at the nor- theastern part of its range failed up to now. Differential diagnosis P. erimanthos is defined by pronotum, elytron and cercus in the male, basal fold of the lower ovipositor valve in the female and size, slender habitus, colora- tion and unarmed hind femora in both sexes. Most obvious feature is the median prominence of the ma- le second tergite by which ?. erimanthos is recogniza- ble at a glance. So far known to us such a structure in Poecilimon exists only in glandifer Karabag, 1950 (Karabag 1950: fig. 7) and ampliatus Brunner von Wattenwyl, 1878 (Krauss 1878: pl. 3 fig. 3a, Harz 1969: fig. 373). The prominence in these species, ho- wever, is located on the first tergite, partly covered by the elytra and differently shaped. Also other features of these species differ clearly from P. erimanthos. Except for the prominence of the second male ter- gite, P. erimanthos comes near the closely related spe- cies laevissimus, werneri and jonicus (s.l.). The male second tergite of P. laevissimus presents no prominence but is slightly inflated, also bristly and of similar colour medially. Other distinctive features (Willemse 1982, Heller 1984) are summarized: male cercus quite larger; stridulatory file less bulged; pro- notal metazona only a little more inflated; same coloration of body but black dots of tergites more sol- id; antennae more widely annulated; basal fold of lower ovipositor valve more and roundly impressed from above, groove larger and more rounded; size of body and legs usually larger but occasionally similar. P. werneri differs in: slightly longer elytra, straight profile of stridulatory file; male cercus more incurved in apical third, tip more pointed; basal fold of lower ovipositor valve slightly arched upward anteriorly and groove with gonangulum more shallow and facing more anteriorly instead laterally; tergites with similar colour pattern but, on either side, an additional black lateral streak (Willemse 1982, 1985a). P. jonicus (s. 1.) can be distinguished by more inflat- ed pronotal metazona; more visible and slightly long- er elytra, file of similar shape but shorter, bulging stronger and more distally, teeth less closely set; male cercus pre-apically more angularly incurved and slightly flattened; basal groove of lower ovipositor valve smaller and round instead elongate and besides in jonicus lobulatus provided with an anterior inflated processus (Willemse 1982, 1985a). The calling song resembles also these last three spe- cies. In P. erimanthos the duration of the closing hem- isyllable of the isolated syllable or of the first syllable of an echeme respectively, is shorter than in P. jonicus jonicus, jonicus lobulatus and werneri (fig. 31, Heller 1984, 1988). Isolated syllables of P. jonicus tessellatus, laevissimus and erimanthos may be indistinguishable from each other. The echeme structure in P. eriman- thos, however, is unique. Echemes in P. laevissimus and werneri were, so far known, not produced at all, while in jonicus (s. |.) the second syllable of an echeme is not restricted to an opening hemisyllable as in er7- manthos but to a closing one or both to an opening WILLEMSE & HELLER: Systematics of Greek Poecilimon and closing hemisyllable (Heller 1984). Discussion We observed that during mating the female nibb- led eagerly at the peculiar prominence of the second male tergite. Further anatomy or function of the pe- culiar prominence of the male second tergite are unk- nown. Etymology A noun in apposition, named after its distribution that centres on Mt. Erimanthos.

Distribution Only known from the eastern Aegean island of Lesvos, at least from its southern part (see remarks be- low). WILLEMSE & HELLER: Systematics of Greek Poecilimon Discussion P. mytilenensis was known only from two males (ty- pe series) and one female (Werner 1934). The mate- rial listed above agrees fully with the descriptions and figures of the male holo- and paratype. Previous de- scriptions (Werner 1932, 1933, Ramme 1933, Harz 1969) are insufficient. Additional material before us from the island of Lesvos: 3 km NW of Kaloni (rrza); N of Kaloni (IT- ZA); Sikaminea (cw) is strongly reminiscent of P. my- tilenensis, particularly the virtually identical male stri- dulatory file. However, the male subgenital plate (fig. 22) is remarkably different: much shorter, much less tapering posteriorly and the apical part not at all pointing dorsally between the cerci. Some other char- acters differ as well but not so conspicuously. It is al- so remarkable that these specimens are from the northern part while typical P. mytilenensis occur in the southern part of the island. Lack of bioacoustical particulars prevents further identification. Poecilimon mariannae sp. n. (figs. 16, 34, 40-41, 43) Poecilimon cf. aegaeus Werner; Heller 1984: 104. [Poecilimon mariannae F.

Bioacoustics. — Male calling song consists of an echeme (Heller 1984; 1988; fig. 34), repeated at intervals of mostly 2-4 s (range 1-7 s; 22-24°C). Each echeme composed of 6-8 (range 4-11) syllables pro- duced in a frequency of about 12-18 Hz (22-26°C). Impulse number per syllable from 6-15, first syl- lable(s) often containing more impulses than follow- ing ones. Impulses produced during closing move- ment of fore wings only, opening being silent. Maximum of frequency spectrum 20-30 kHz. Distribution and ecology The song of this species has been observed at the localities of the material listed above but also at many other localities: Dhomokos (near Metallion; A. Stefanos; Perivoli; Makrirakhi; between Dhomokos and Neo Monastiri); Farsala (very abundant near Vrisia; Khalkiadhes); Larissa (Khara; Zappion; Nees Karies; Larissa town); Kardhitsa (Sofadhes; Kombelos; eastern side Kardhitsa town). So far the range of the species extends from northeastern Central Greece (Fthiotis: Dhomokos) north- and northwestwards into Thessalia, reaching the town of Larissa and Mouzaki, beyond the town of Kardhitsa. Localities referring to preserved material are mapped as solid squares, those based on acoustic observation as open ones (fig. 43). We found the species on thistles and other plants mainly on the wayside and adjacent fields. It was common in the plains S of Dhomokos, around Neo Monastiri and N of Farsala and locally very abun- dant. The range of P. mariannae is overlapped by those of veluchianus and propinquus. At most sites only one of these species occurs, at some more than one. Near Dhomokos, NW of Vrisia and some other localities the new species was found syntopically with P. pro- pinquus. Along the southern border of the plain S of Dhomokos a narrow zone of syntopical occurrence of P. mariannae and veluchianus was detected, the latter inhabiting the still more southern located slopes that border this plain. At one spot, Makrirakhi (W of Dhomokos) we heard simultaneously the calling songs of even all the three species. Whether P. mari- annae occurs syntopically with chopardi and thessalicus is still unknown. The areas where this might occur, N and W of Larissa, have not yet been explored (fig. 43). Differential diagnosis The species is virtually identical with P. chopardi except for its different song. We found only one morphological character that might be helpful to dis- criminate both taxa: spacing of the teeth of the stri- dulatory file of the left male elytron is greatest in the mid part of the file with 11-12 in the new species against 8-10 teeth per 0.5 mm in P. chopardi. Similar features to differentiate P. chopardi from the thessali- cus - veluchianus - zimmeri group of species fit ma- riannae (Willemse 1985a). Bioacoustically, however, the new species is clearly defined by its song, differing in several characters from P. chopardi (Heller 1984; 1988). Most reliable and recognizable feature is the syllable number per echeme, 6-8 in P. mariannae against 3-4 in chopardi. Echemes with a different number of syllables are produced sometimes, viz. down to 4 in P. mariannae and up to 5 in chopardi. However, this happens quite exceptionally and bes- ides irregularly by few specimens only. Also the sylla- ble repetition rate within an echeme is different: P. mariannae about 13 Hz and chopardi 9 Hz (both at 25°C). Different ambient temperature, however, im- pedes the use of this character in the field. Finally, the syllable structure is different: all intervals are equally spaced in P. mariannae whereas each syllable consists of two groups of impulses separated by a longer inter- val in chopardi. Besides the number of impulses per syllable in P. mariannae appears to be smaller than in chopardi. Bioacoustical distinction with the P. thessa- licus - veluchianus - zimmeri group of species is ob- vious. WILLEMSE & HELLER: Systematics of Greek Poecilimon Discussion It is noted here that most previous records of P. chopardi (Willemse 1985a: 20) are based on morpho- logical characters only. Confirmation by the song is certainly needed. Etymology Named in honour of Marianne Volleth, who found the first specimens.

Distribution and ecology The range is much larger than previously known (Willemse 1985a: map 6), extending into eastern Arta, northeastern Aitolia-Akarnania, extreme north- ern Fthiotis as far as eastern Magnisia. The occurren- ce in Mt. Tzoumerka (Arta) was doubtful (Willemse 1985a) but has now been established. Previous re- cords of syntopic occurrence of P. veluchianus with other congenerics are confused (Willemse 1982, 1985a). So far known the species may occur together with P. ornatus, hoelzeli, gracilioides, chopardi, ma- riannae, jonicus lobulatus, propinquus and most im- portant zimmeri (see below). Previously we knew P. veluchianus only from montane habitats but the spe- cies may occur in the lowlands as well: e.g. Fthiotis: Vitoli 330 m (Heller 1988); surroundings of Lamia 100 m and many localities in the Sperkhios valley fr- om Sperkhiadha to Lamia. Discussion P. thessalicus, veluchianus and zimmeri are very sim- ilar in their morphology and bioacoustics. While their distribution areas do meet, no clear overlaps ex- ist. Stressing the similarities and allopatric distribu- tion, these taxa have been considered subspecies by Heller (1984, 1988), while Willemse (1985a) argued 318 TIJDSCHRIFT VOOR ENTOMOLOGIE, VOLUME 135, 1992 that their differences were comparatively large and sufficiently stable to consider them species. Recently, syntopic occurrences of P. veluchianus and zimmeri have been established: based on the male calling song, a 300 m wide zone was discovered, on the transition between the plain (P. veluchianus) and mountain slopes (P. zimmer) near Lilaia (Fthiotis), in which both taxa occurred; likewise, in the same area an isolated population of P. zimmeri was discovered within the range of veluchianus, while the songs of both taxa was heard on the boundary of both popula- tions; syntopic occurrence of both taxa was also found near the summit Piramidha of Mt. Valtou (N of Perdikhaki, NE Aetolia-Akarnania) and the type lo- cality of P. gracilioides on Mt. Tzoumerka (S of Theodhorania, E of Arta). In all these localities no hy- brids were found. We believe that the syntopic occur- rence of veluchianus and zimmeri and the apparent absence of hybrids provides a strong enough argu- ment to consider these taxa species and not subspe- cies. Recent experimental studies on interbreeding between P. thessalicus and veluchianus reveal that they mate readily but do not have offspring (K. Reinhold, Erlangen, pers. comm.). Though syntopic occurrence of these taxa has as yet not been established both au- thors now agree that both taxa are best reflected by a species rather than subspecies level. Specimens from Fthiotis and Magnisia are remarkably slender, small in size and the armature of the male cercus is restrict- ed to the inner apical margin. Their song is not dis- tinctive from the remainder of the range. So far, these populations are considered conspecific with P. velu- chianus, but further studies are currently in progress.

Material studied. — Magnisia: Mt. Othris above Kokkotoi 1100-1500 m (cw); Larissa: 2 km N of Vrisia 450 m; 4 km N of Zappion; Fthiotis: Dhomokos 500 m (all cH); Attiki, Skinios ; Mt. Parnis 1200 m; Avlon (all cw). Distribution and ecology Previously known only from the eastern Peloponnisos, Attiki and Evvoia (Willemse 1984: map 27), the range of this species extends remarkably more northward reaching the districts of Larissa and Magnisia. In Fthiotis and Larissa we found the species on thistles and other plants on the wayside and ad- jacent fields, on Mt. Othris mainly on ferns. Syntopic occurrence of P. propinquus with marian- 314 nae has regularly been observed (see mariannae). P. propinguus and veluchianus were found together in the northern hills of the Sperkhios valley and in Mt. Othris. In most of these places one species was ex- tremely predominant or occurring without competi- tors at one spot and with true syntopic occurrences at the borderlines only. Discussion The apical margin of the male cercus was known to be convex (fig. 17, Ramme 1933, Willemse 1982) but in the northern specimens from Magnisia, Larissa and Fthiotis it is scarcely convex or even straight (fig. 18). Bioacoustics are somewhat variable and for the time being we consider these populations conspecific as the song seems identical.

The editors particularly invite papers on the insect fauna of the Palaearctic and Indo-Australian re- gions, especially those including evolutionary aspects e.g. phylogeny and biogeography, or ethology and ecology as far as meaningful for insect taxonomy. Authors wishing to submit papers on disciplines rela- ted to taxonomy, e.g. descriptive aspects of morpho- logy, ethology, ecology and applied entomology, are requested to contact the editorial board before sub- mitting. Usually such papers will only be accepted when space allows. Papers in English are preferred, but papers written in French or German will also be considered. It is our policy that papers are reviewed by an external referee. Authors will generally be notified of acceptance with- in two months. For the first submission two printed copies (or photocopies) are required, including photocopies of figures, reduced to A4 format. Diskette and original artwork should not be sent until the paper is accep- ted. Manuscripts should preferably be printed on A4 size paper, on one side only, double spaced, with a left margin of at least 4 cm. Authors not able to use a wordprocessor, are required to submit a neatly typed original, conforming to the same standards, without any handwriting on it; any remarks should be written on a separate piece of paper or a photocopy. After ac- ceptance of a paper, authors are requested to prepare a manuscript according to standards given in a sepa- rate style-sheet. These instructions include e.g. the wordprocessing programs we can handle and the co- des that should be included or are allowed in your fi- les. The editors can handle the most common word- processing programs for MS-DOS and Macintosh systems, but prefer Wordperfect (any version) or MS- Word. Lengthy papers (more than 40 pages in print) are only accepted when space allows. Publication can be speeded up by paying a page-charge of Hfl 50. Otherwise no page-charge is asked. Membership of the ‘Netherlands Entomological Society’ is not obli- gatory. Text preparation A cover page should provide the names of the au- thors and a proposal for a running title. The second vi page starts with author names (in all capitals), use & for ‘and’, on a new line the name of institute (as short as possible), with multiple authors using superscript ' ° etc. The title is brief and informative, typed in all ca- pitals, with order and family of the taxon treated in parentheses. The abstract starts with a bibliographical reference (authors, year, title), see recent issues for layout. Then the abstract follows, without the word ‘abstract’ and without indentation. The abstract, written in English, should be concise, yet cover the main results of the paper, including new taxa and nomenclatorial changes. The name and address of one and only one of the authors follows, if needed preceded by the word ‘Correspondence:’. This should also be the ad- dress for the galley proofs. The abstract ends with a list of key-words. The text proper starts on a new page, the introduc- tion (if any) starts without heading. Use a maximum of three categories of headings, all to be typed left, and using capitals and lower-case letters. The first ty- pe may also be typed in small capitals, the second and third type may be typed in bold. After the heading the paragraph follows without blank. A fourth category may be used in descriptions of species, etc. It is sepa- rated from the following paragraph by a long dash (—) to be typed as double dash. New paragraphs should not be indented in word- processors. Scientific names of genera and species should be typed in italics or underlined. No underli- ning or italics are allowed for any other text. Abbreviations of museums (‘codens’) etc. should be typed in small caps, if available. References In the text they are given as Lopes (19822), (Lopes 1982) or (Brown & White 1975: 24). All cited papers should be listed alphabetically at the end of the paper under the heading ‘References’, papers not cited in the text should be omitted from the list of references. Examples for format: Boer, P. J. den, 1970. On the significance of dispersal power for populations of carabid-beetles (Coleoptera, Carabidae). — Oecologia 4: 1-28. Karsholt, O. & E. S. Nielsen, 1976. Systematisk fortegnelse over Danmarks sommerfugle. — Scandinavian Science press, Klampenborg, 128 pp. Johansson, R. & E. S. Nielsen, 1990. Tribus Nepticulini. — In: Johansson, R. et al. The Nepticulidae and Opostegidae (Lepidoptera) of NW Europe. — Fauna en- tomologica scandinavica 23: 111-238, pls. Titles of journals should not be abbreviated. Type long dashes as double dash ‘- -’. Do not try to type in- dentation, just end each reference with a hard return. Nomenclature The latest edition of the ICZN Code should be fol- lowed. The composition of new names should pre- ferably be explained in a paragraph ‘Etymology’, in- cluding indication of gender of generic names and kind of specific name (adjective, noun in apposition, etc.). Use standard abbreviations: Sp. n., gen. n., comb. n., syn. n., sp. rev., nom. n., etc. For all genus and species-group names the authority (preferably with year of description) should be mentioned once. Author’s names are not abbreviated. In new taxa the type material should be listed im- mediately after the name. Only holotype, lectotype, neotype, paratype and paralectotype are allowed. Label data should not be quoted literally (except for primary types), but arranged in a standardized se- quence. Material should be listed alphabetically or chronologically under the present day countries or other geographical units. Long lists of non-type mate- rial should be summarized. Geographical names should be written according to present day spelling, original spelling or label names may be given in brackets. Use standard transcription for non-latin scripts (e.g. Pinyin for chinese, BSI for cyrillic, etc.) or refer to the “Times Atlas of the World’. Abbreviations (Codens) for depositories preferably follow Arnett & Samuelson (1986: The insect and sp- ider collections of the world. E.J. Brill/Flora & Fauna publications, Gainesville). Otherwise, they should be listed under ‘Material and methods’ or in the intro- duction. Data for primary types of previously described spe- cies follow directly the reference to the original de- scription as: Elachista subnitidella Duponchel, [1843]: 326, pl. 77: 8. Lectotype & [designated by van Nieukerken & Johansson 1987: 471]: [Austria, Vienna region], Duponchel coll., Genitalia slide EVN 2522 (MNHN) [examined]. Illustrations All illustrations, including photographs, graphs, maps, etc. should be serially numbered as figures. No subdivision with letters is recommended. Illustrations are to be reduced to column width (65 mm), 1.5X co- lumn width (102.5 mm) or text width (135 mm). Line figures should be mounted in blocks, or are prin- ted singly. When all figures are mounted in full-page blocks (after reduction: 135x195 mm including cap- tion), they may be printed after the text, otherwise the approximate place in the text should be indicated with pencil in the margin of the manuscript. Line- drawings are numbered with pre-stencilled or pre- printed figures, which should not be too large after re- duction, preferably using a font like ‘Garamond’ or ‘Times’. Photographs should be unmounted glossy prints. Numbering of photos should be left to the dis- cretion of the editors. Captions should be typed on a separate sheet (or in a separate file), consult a recent issue for style. Colour plates will only be printed at the authors expense. Tables Tables should be typed on separate sheets (or files), starting with the captions. When using a wordproces- sor: start with a practical TAB setting, and use only one [TAB] code for each next column. No formatting with spaces is allowed. No lines should be added. Extensive and long tables should be avoided. Proofs, reprints Authors receive one proof only, which should be corrected and returned immediately. When correc- tions are few, sending per telefax is recommended. Authors receive 50 reprints free of charge. Additional reprints can be ordered when proofs are returned. Members of the Netherlands Entomological Society receive a considerable dis- count. Covers can be ordered at extra cost.
