Papers in the Bulletin are primarily the results of research carried out on the unique and ever-growing collections of the Museum, both by the scientific staff of the Museum and by specialists from elsewhere who make use of the Museum's resources. Many of the papers are works of reference that will remain indispensable for years to come. Parts are published at irregular intervals as they become ready, each is complete in itself, available separately, and individually priced. Volumes contain about 300 pages and several volumes may appear within a calendar year. Subscriptions may be placed for one or more of the series on either an Annual or Per Volume basis.

G. Thomson are catalogued. An attempt is made to account for the type-material of all species and the generic placements of the species to which the names apply are established after study of the types. Types of 74 species are lost and 9 names remain nomina dubia. Lectotypes are designated for 116 species and 103 new combinations are established. One neotype is designated and one replacement name is proposed. Introduction The Ichneumonidae is one of the largest families of animals. More than 10000 species have been described from the western Palaearctic region alone. Because of their parasitic habits they are of great economic importance and biological interest. However, studies of their 'biology' depend upon a sound and accurate knowledge of their taxonomy. It is unfortunate that the taxonomy of the western Palaearctic fauna is currently more confused and in need of attention than that of any other zoogeographical region. The main reason for this is that the results of the outstanding work over the past forty years by Henry Townes and his co-workers, on the taxonomy and classifi- cation of the family, have now been applied to all other regions and have wrought order from chaos. There is a firm base for future systematic studies on the family in these areas. A similar base, in the form of comprehensive modern 'catalogues', is needed for the western Palaearctic. The word catalogue is used with some reservation because it tends to convey the wrong im- pression of the kind and quality of studies needed to produce such works, for a group as large and as difficult as the Ichneumonidae. This paper on the Thomson species is intended as a contribution to a complete catalogue of the western Palaearctic Ichneumonidae. Bull Br. Mus. not. Hist. (Ent.) 45(1): 1-119 Issued 27 May 1982 2 M. G. FITTON C. G. Thomson is generally acknowledged to have been one of the most able hymenopterists of his period. He had a talent for distinguishing closely related species and he described a very large number of new species, including 957 Ichneumonidae, all from Europe and mainly from Sweden. However, his ability is not fully demonstrated in his publications; he lacked a type-concept; and he neglected the proper labelling of material. The existence of these deficiencies perhaps helps to explain how he was able to be so prolific; and, together with the recent revolutionary changes in the classification and taxonomy of the Ichneumonidae, they now limit seriously the use which can be made of his work. This paper attempts to place all of the species of Ichneumonidae described by Thomson in the currently-accepted generic classification of the family. This sort of work must precede revisionary studies because, if such studies of genera or higher taxa are to have a lasting value, one of the essential prerequisites is a knowledge of the described species which belong to them. Because of the vast literature this problem has bedevilled taxonomic work on many groups of European insects, but it is especially severe in the large and difficult families of parasitic Hymenoptera such as the Ichneumonidae. That the work of correctly placing the already-described species of western Palaearctic Ichneu- monidae cannot be achieved successfully, as revisionary studies are undertaken, can be dem- onstrated easily by reference to the Thomson species. For instance, in a revision of Dichrogaster, a small distinctive genus with nine species in Europe, Horstmann (19736) included only two of the four Thomson species which belong in it (Horstmann, 19766). Thomson originally described three of these species in Hemiteles and one in Phygadeuon. Recognition of the genuine types of Thomson's species has also caused problems (the reasons for which are fully explained in the sections on labelling of specimens and recognition of types). Of about 400 specimens designated as lectotypes or recognised as holotypes of Thomson species between 1966 and 1978 more than twenty-five can now be shown not to have been original material of the species concerned and therefore to be invalid. For example, Aubert (19766: 271) designated as lectotype of Mesoleius frontatus Thomson a specimen labelled '50', the significance of which was not stated. However, Aubert had the handwritten label upside down; it was really 'OG', an abbreviation for Ostergotland. Since the species was described from Ystad in Skane this specimen could not be a type. These sorts of problems can only be solved by comprehensive studies of all species described by an author and of his methods, collections and idiosyncracies. The generic classification of the Ichneumonidae which is the basis of the placements given in this paper is that published by Townes (1969; 19700; 19706; 1971). This work does not cover the subfamily Ichneumoninae, in which case Townes, Momoi & Townes (1965) and Perkins (1959; 1960) are followed. Placements of species of Anomaloninae and Ophioninae were made by I. D. Gauld and follow his work on these groups (Gauld, 1976; 1979). The classification of parts of the Phygadeuontinae and Tersilochinae takes into account some changes and new genera proposed by Horstmann (19716; 19746; 1976a; 1978). Aubert (19766), Frilli (1973) and Horstmann (1979a) have made particular studies of the Thomson species originally described in Mesoleius, Phyga- deuon and Hemiteles respectively. In these three genera, where I have not felt the need to check, the generic placements are credited to these authors. All species synonymies are given on the basis of the published opinions of competent workers (to which references are given). C. G. Thomson The following biographical information, relating particularly to Thomson's work on the Hyme- noptera, is taken mainly from the obituary by Bengtsson (1900). Carl Gustav Thomson was born in the province of Skane on 13 October 1824 and died in Lund on 20 September 1899. He succeeded Dahlbom as curator of the entomological collections at the University of Lund. He was extremely productive: his first paper appeared in 1851 and his total entomological publications exceeded 8800 pages. Coleoptera were his initial interest but he soon became involved with the work on Hymenoptera which occupied him until his death. He was a popular teacher of entomology and students were sometimes given specimens, from his collections, of the species dealt with in his lectures. The Proctotrupoidea was the subject of his first important work on Hymenoptera. Between THE ICHNEUMONIDAE DESCRIBED BY C. G. THOMSON 3 1871 and 1879 he published the five volumes of Hymenoptera Scandinaviae. The Opuscula En- tomologica, issued in 22 parts between 1869 and 1897, included all of his major work on the groups of Hymenoptera not covered in Hymenoptera Scandinaviae. He paid for the printing of the Opuscula Entomologica himself. Publication ceased in 1897 because problems with his eyesight put an end to his taxonomic work. Of the Hymenoptera, only the Formicidae and Mymaridae did not receive his attention. Although he described over 2400 new species (including more than 2100 Hymenoptera) he apparently regarded his work on higher classification as more important. He dealt mainly with the Swedish fauna and collected most of the material on which he worked himself. The 'biology' as well as the morphology of the species interested him and he spent a lot of time in the field. In summer he went on walking tours, mainly in southern Sweden (including most parts of Skane). He also visited Blekinge, Halland, Smaland, Oland and Gotland. He was often accompanied by C. D. E. Roth. At the end of the 1860s he went twice to Norrland and in 1871 visited Jamtland. He travelled abroad to Germany and in 1872 made a long trip to Germany, Austria, Switzerland and France, during which he visited many museums and saw important collections (including those of Fabricius and Hartig). Thomson did not spend much time preparing specimens, which were often pinned alive in the field. At the time of his death his collection of Hymenoptera comprised about 80 000 specimens representing about 7000 species and was housed in 78 cabinet drawers. Acquisition of Thomson's collections by the University of Lund Thomson's collections were his own private property. He himself sold his collection of Coleopt- era (but not the 'duplicate' collection) to Berlin (see Charpentier, 1972). In November 1899, after his death, his daughter offered the remaining collections for sale to the university. She said that Thomson had valued the collections at between 20000 and 30000 Kr. but she asked for only 8000 Kr. Together with the written offer to the university she included a synopsis of the col- lections. The Ichneumonidae occupied 35 cabinet drawers and there were about 30 boxes of 'duplicate' material. The collections were purchased by the university on 23 January 1900. Manuscript and other material associated with the collections Thomson's correspondence is deposited in the main university library in Lund. He was in contact with workers in Sweden and in Europe, including most contemporary ichneumonid specialists. Many of the letters are accompanied by lists of species. The library of the Zoological Institute has Thomson's personal copies of the Opuscula En- tomologica, etc. They contain marginal notes made by Thomson. The notes are more numerous in the earlier parts and include new synonymy and descriptions of new species. Unfortunately, they have not proved helpful in tracing the type-material that is apparently missing from the collection. The Entomology Museum of the Zoological Institute has little manuscript material that is relevant to the Ichneumonidae. It includes the letter from Thomson's daughter offering the collections to the university (see above) and a few lists, including one of ichneumonids from Holmgren's collection. The collection of Ichneumonidae Thomson's 'main' collection of Ichneumonidae is contained at present in parts of two cabinets (numbered 395 and 396). It occupies 50 drawers (numbered 31 to 80). The arrangement of the collection follows the Opuscula Entomologica, thus: Ichneumonidae (drawers 31-41), Cryptidae (41-50), Pimplidae (50-56), Agriotypidae (56), Ophionidae (56-65) and Tryphonidae (66-80). The 'duplicate' ichneumonid material is contained in various cabinet drawers (in cabinets 398, 399, 403 and 404) and in numerous separate boxes (cigar boxes etc.). The boxes are kept in cupboard 324. Parts of the duplicate collection (boxes as well as drawers) are arranged taxo- 4 M. G. FITTON nomically, with labels for genera and species. In some parts the arrangement is tidy and it is possible to relate specimens to particular labels. In other parts there is a confusion of material. Some boxes contain material from a single collector (e.g. Lethierry); others contain an assort- ment. The contents of some boxes are partly sorted and named. The duplicate collection includes Dahlbom, Ljungh, Holmgren, Wesmael and Zetterstedt material. There is type-material of Thomson species and there may be type-material of other workers species (notably Holmgren and perhaps Wesmael). Thomson apparently received a collection of Wesmael ichneumonids (currently in two drawers in cabinet 399). It is still 'as received', each specimen bearing a number (1-249). No key to the numbers, and thus Wesmael's identifications, has been found. The 'main', formal collection was arranged in its present form by Simon Bengtsson. Bengtsson was appointed curator of the entomological collections in 1900 and one of his first duties was to take care of the then newly-acquired Thomson collections and transfer the Hymenoptera to three new cabinets. It is known that the formal collection corresponds to Thomson's own 'main' collection but that the arrangement may have been changed (if necessary) to correspond with the Opuscula Entomologica. The 'duplicate' collection appears to be as Thomson left it. The only significant curatorial work on the collection since Bengtsson's time has been the recognition and labelling of type-material by specialists and, more recently, the addition of labels (in the form '1978 329') to specimens sent out on loan. These labels are not removed when the specimens are returned to the collection and they form, in conjunction with the 'loan journal', a useful record of borrowers of material. Some years ago a few specimens were labelled 'typ' or 'typi' (e.g. Cteniscus genalis) as part of a curatorial exercise attempting to identify types/syntypes in the museum collections (not just the Thomson collection) (H. Andersson, pers. comm.). There are surprisingly large numbers of specimens missing from the collection (deduced from information on localities, sexes and specimens given in the Opuscula Entomologica). There are several possible explanations for this but none is supported by more than circumstantial evi- dence. There is some Anthrenus damage in the collection but very little evidence of attacks in the present cabinets. Perhaps badly damaged specimens, including type-material, were discarded at some time by Thomson, or by Bengtsson at the time of the transfer to the present cabinets. The collection was undoubtedly a 'working' collection and Thomson may have redetermined material at various stages, changing its position in the collection. Some such displaced specimens have already been identified as types. It is probable that Thomson exchanged material with other European workers. As far as is known, however, he did not give any of his Swedish material to other Swedish workers (H. Andersson, pers. comm.), with the possible exception of specimens of common species given to students (Bengtsson, 1900). He may have returned to other Swedish workers specimens which they sent to him. He returned to Jensen and to Drewsen material, including types now in Copenhagen, which they collected in Jutland and Zealand. It is difficult to assess the effects of the transfer to new cabinets and associated curatorial work by Bengtsson. Thomson's arrangement was almost certainly not as precise and neat as the present one. Bengtsson replaced Thomson's handwritten 'cabinet' labels by type-written ones. In the case of generic names Thomson's labels were concealed beneath the new ones. The species name labels were folded and transferred to the pin of the first specimen in the species series. The type-written labels follow the Opuscula Entomologica exactly and include the typographical errors, e.g. Microcryptus 'arrideus' instead of 'arridens' as on Thomson's own cabinet label and Exetastes 'guttiferri instead ot'guttifer'. In some cases Thomson's cabinet label name differs from the published one, e.g. Catoglyptus fusiventris" instead oi'fusiformis1 — presumably he changed his mind between writing the label and writing the manuscript for publication. Labelling of specimens Apart from Thomson's cabinet labels (added to specimen pins by Bengtsson (see note above) and of no significance whatsoever in the recognition of types) material in the collection is usually very poorly labelled. The specimen labels are generally small squares of paper with an abbreviated THE ICHNEUMONIDAE DESCRIBED BY C. G. THOMSON 5 locality name and sometimes a date. The locality labels may be handwritten or printed. Oc- casionally the locality name is given in full. Some specimens have no locality name or abbrevi- ation but instead have a small square of coloured paper. Unfortunately, the meaning of only one colour is known: green indicates Ringsjon. There are two kinds of green squares, very small dark ones and slightly larger (up to about 3x4 mm) paler, brighter ones. Interpretation of the small dark labels as indicating Ringsjon is now generally accepted (for example, Huggert, 1973: 107; Aubert, 1976a: 154) and I have discovered specimens bearing both a green square and a printed label 'Ringsio'. Similar systems of coloured labels were used by other contemporary and earlier workers, for example Zetterstedt (R. Danielsson, pers. comm.). Specimens sometimes also have other labels, usually of one or more of the following four kinds: a sex sign (printed); the name of a collector or collection; an additional locality label giving a province or country; an identification. The style of label with a locality abbreviation used by Thomson was also popular with other contemporary collectors — most notably C. D. E. Roth who often accompanied Thomson on his collecting trips. Thomson's and Roth's handwriting styles were similar and most labels are Ibrekovl* B5stad« •Osb-a Karup narcjret'el'orp • Rossjoholm Kungsmarken* •Reuen -•Lund •frS3elsan3 Kallby^RSby •TornaHallestod'Ovedskl aster •Atnarp •Dolby yddingesj6n/^»Holmeja rsjo* '-'•Bokeberg Map 1 The Swedish province of Skane showing the type-localities of species of Ichneumonidae described by C.

The labels are poorly written and hard to interpret until one is familiar with the forms of individual letters and the locality names from which the abbreviations are derived. A list of abbreviations used for Swedish localities is given below. It is not exhaustive and relates mainly to ichneumonid type-material.

Thus, specimens of a species stated in the description to come from Palsjo may be labelled 'Hbg' (= Helsingborg), Palsjo being a district of Helsingborg. (Other specimens are actually labelled 'Pal'.) The terms Norrland and Lappland were used rather imprecisely and sometimes inter- changeably by Thomson. Norrland is the area of Sweden north of and including the provinces 8 M. G. FITTON Harjedalen and Halsingland. Species stated to come from Lappland are often labelled Norrland and vice versa. A list of the localities which it is assumed Thomson 'bracketed' is given below. Helsingborg includes Palsjo fKlinta Rmgsjon includes < _ , (Stehag ... . fHolmeja Yddinge includes < „ [Bokeberg Norrland includes Lappland Jamtland Halsingland Specimens from particular collectors or collections were known by Thomson to come from a particular locality. For instance, Ljungh specimens come mainly from Smaland and if Smaland is given as a locality for a species the relevant specimens may actually be labelled 'Col. L-gh' but without a locality label. Rudolphi collection specimens originate mainly from Halsingland and Fallen specimens from Asperod (near Kivik). Notes on the recognition of type-material and on the selection and designation of lectotypes Thomson did not have a type concept in any modern nomenclatural sense. He made no attempt to preserve or label in any particular way the specimens which were the bases of his descriptions of new species. Usually Thomson gives no direct details of specimens with original descriptions, only the localities or more general areas where the species had been found, such as 'Funnen vid Holmeja i narheten af Yddingesjon' and 'Funnen vid Degeberga i Skane'. For several species much less precise locality information is given, for example, 'Ej sallsynt i norra och medlersta Europa', or sometimes none at all. Localities outside Skane are often only given at the level of province ('Oland' or 'Norrland', for example) or country. In the latter case Thomson may not have been able to decipher abbreviations, read handwritten labels or ascertain the correct geographical positions of the localities of material obtained from foreign workers. Information in addition to the locality, when any is given, includes habitat, date, collector, an indication of abundance and host data. Examples, 'Funnen vid Kjeflinge i barrplanteringen', 'Funnen i September vid Ortofta nara Lund', 'Funnen talrikt vid Ilstorp i Skane af Conservator C. D. E. Roth', 'Sallsynt; funnen pa sandmarker pa Oland' and 'I Munchen utklackt ur Thecla Betulae af D : r Kriechbaumer'. More precise information about the specimens themselves is given only rarely, and often when there was only one, for example, 'Exemplaret, en hona, ar funnet pa Gottland' and 'Endast ett ex. fran sodra Frankrike (Coll. Lethierry)'. Thus Thomson's lack of attention to original material; the inadequate published information; the poor labelling of specimens; and changes in the arrangement of the collection subsequent to publication all hinder recognition of type-material. Indeed, for most species it is impossible to be absolutely certain which specimens are types. On the other hand this combination of poor information gives wide scope in deciding which specimens are possible types. It also leaves open the possibility that a specimen chosen as a primary type may be shown, at some later date and in the light of further evidence, not to have been used as the basis of an original description. However, practical considerations justify the selection of single primary type-specimens (usually lectotypes) to serve as stable bases for the nomenclature of the species. Of the specimens standing under the name of a Thomson species in his collection I have recognised as syntypes all those which are in agreement with the description and with the other information (on localities, etc.) given in the original publication. This latter qualification would perhaps be better expressed as lack of disagreement because, for example, where Thomson cites a THE ICHNEUMONIDAE DESCRIBED BY C. G. THOMSON 9 locality within a province and there are specimens labelled only with the name of the province they have been accepted as syntypes. Thomson's subsequent references to his own species are sometimes helpful in deciding on the limits of a syntype series. Syntypes of some species are in other collections. For a few species specimens under other names have been regarded as syntypes, usually on the basis of precise agreement with descriptions and other information, and evidence of changes in that part of the collection subsequent to the relevant publication. It is not always easy, using the above criteria, to decide whether or not a particular specimen should be included in a syntype series. Problems are caused by minor disagreements with descriptions; illegibility of labels; interpretation of locality abbreviations on labels and of col- oured tags; and differences between localities as published and as given on labels. Agreement of specimens with descriptions calls for a subjective judgement, sometimes open to alternative opinions. The questions relating to labelling and localities are dealt with in the previous section on labelling of specimens. Each case has to be judged on its individual merits, paying attention to the utility of the particular situation. Thomson described many new species from single specimens (holotypes). In some cases there can be no doubt, for example, 'Ett exemplar fran Smaland'; in others it must be inferred from the published information together with the fact that there is only one specimen in the collection. Some workers object to recognition of specimens of the latter kind as holotypes. In cases which I consider doubtful I have cited such specimens as single surviving syntypes. Any member of a syntype series is eligible for designation as lectotype of the nominal species concerned. Lectotypes have already been designated (published) for a lot of Thomson's species. Many others have been selected (labelled) but not yet published. Lectotypes already selected but not published are designated in the present work, but where no lectotype has been selected details of the syntype series are given. Only a few lectotypes have been selected and designated by me, usually in cases where previous designations are invalid for one reason or another. Lectotype designations are best made in the context of a complete revision of the group to which the species concerned belongs. However, for reasons of practicality it was thought desirable to publish here the selections already made by other workers (some as long ago as 1954). A number of the lectotype designations already published call for comment. Several are casual in the extreme and need careful consideration of their validity in relation to the relevant provis- ions of the International Code of Zoological Nomenclature. Others, such as Aubert's lists (1966; 1968; 1972) of indiscriminately chosen species, have been published as ends in themselves. Much more attention must be paid to the publication of lectotype designations. There are too many references such as 'lecto. des Townes, 1958', not meaning that there is a designation published by Townes in 1958 but that the specimen was labelled by Townes in that year. It often happens that such a reference to the label is the first publication of a lectotype for that species. Are such references valid designations? For practical reasons they are best accepted as such but the situation is far from satisfactory. Editors of journals, as well as authors, must take some of the blame for this state of affairs. Thomson's use of names for subgeneric categories Thomson's use of names for 'subgenera' was inconsistent and is difficult to interpret. This incon- sistency is not surprising in work published over a long period but, as a consequence, determining the original subgeneric (and sometimes generic) placements of species is not always easy. Even when Thomson used subgenera clearly he often prefixed the name of each species with the initial letter of the subgeneric and not the generic name, for example, in Mesochorus (1886a: 327-344). Workers who have not studied Thomson's work properly have been misled by this practice into citing incorrectly original generic placements. Of more importance is Thomson's habit of giving genus-group names in parentheses at various points in his keys to species. The names used in this way are mainly those originating from Foerster's work (see Perkins, 1962: 387). In some cases the rank of such names as subgenera is clear because Thomson gives a 'Conspectus subgenerum' at the beginning of the genus, some- times including synonymy, for example, Megastylus (18886: 1310). In other cases Thomson does 10 M. G. FITTON not give such an indication or the names are given so as to apply to groups of species within subgenera, for example, the use of Myriarthrus within Megastylus subgenus Megastylus (1888b: 1314). Thus, it is not always clear whether the names apply to formal subgenera; formal infra-subgeneric categories ; informal groups of species ; or are included for purposes of synony- my. They are important because they are often the first association of species with Foerster generic names (Perkins, 1962). Subsequently the names have been cited most frequently as subgenera. Except for those used by Thomson infrasubgenerically they are treated uniformly as subgenera in the present work, but because of the doubt about many of them the catalogue section is arranged in alphabetical order of binominal, and not trinominal, combinations. Format and arrangement of catalogue The catalogue section is arranged in alphabetical order of the original binominal combination (that is, disregarding any subgeneric component of the name). The nomenclatural summary which follows the catalogue and the index provide entry into the catalogue via species names, subgeneric placements and current combinations. For each nominal species the entry is arranged in the following sequence : Name; date and page reference of original publication; status and sex of primary type(s); type- locality; type-depository; lectotype designation or reference to previous valid type-restriction (when necessary). Details of the labels on the specimen(s). Notes. A statement, prefixed 'Identity', on the generic placement and synonymy of the species. The following points should be noted with regard to these data. The name is given as published except that the orthography is altered to comply with Articles 26, 27, 28 and 32 of the Code when necessary (in which cases the form of the name as published is also given). Swedish type-localities are given as cited by Thomson with the addition of the names of the country and province (when necessary) and the modern spelling (when different). Names of type-depositories are abbreviated as in the list below. Where types are lost this is stated in place of a depository. The collections from which Thomson described species are given after each depository.

For each label an indication is given (in square brackets) of whether it is handwritten or printed. Except for a few species with large syntype series, all primary type- specimens have individual modern labels showing their identity and status. Catalogue Acanthocryptus nigriceps, 1883: 868.

J. LEWIS Introduction General Phlebotomus Rondani & Berte is one of the two Old World genera of Phlebotominae and includes all the habitual mammal-biters and the vectors of human leishmaniasis in the Old World. Disease of this group have recently increased in several countries and epidemics have followed interruption of malaria control, so that renewed concern about the diseases and new research programmes demand up to date information about the vectors. During the past 80 years intensive study has yielded many widely scattered publications about Phlebotomus, particularly from leishmaniasis areas (Anonymous, 1977), and reviews of the genus in three zoogeographical regions have been published. Many species occur in all three of them (Lewis, 19786: 311), and a general survey is required. The present work deals with some basic aspects of Phlebotomus throughout the Old World. The classification of Phlebotomus and the Phlebotominae has been discussed by Abonnenc (1972), Fairchild (1955), Lewis et al (1977), Theodor (1948; 1958) and others. I recognize the division of the living Phlebotominae into five genera, Phlebotomus and Sergentomyia Franga & Parrot in the Old World and Warileya Hertig (Fairchild, 1955: 183; Lewis et al., 1977: 325), Brumptomyia Franga & Parrot and Lutzomyia Franc, a in the New World. Ready et al. (1980) have stressed the undoubted importance of subgenus Psychodopygus Mangabeira of Lutzomyia and treated it as a genus. Lewis et al. (1977: 324) gave reasons against such a course which would involve the elevation to generic rank of several, much more distinctive, Old World subgenera of sandflies and could lead to a general multiplication of genera. Such questions are among the 'pitfalls of perfection' (Nelson, 1978) and are 'handicaps of the human need to compress into linear form the three dimensional world of nature' (Campbell, 1974: 15). Taking a world- wide perspective, I regard Psychodopygus as an important subgenus without changing its rank. Publications (most with keys) dealing with Phlebotomus in various areas include the following. The Old World: Artemiev (1979: 19, Euphlebotomus; 1980, Adlerius), Lewis (1973), Theodor (1948). The Palaearctic Region: Artemiev (1978, key with figures for Afghanistan), Croset (1978: 713, key with figures for Tunisia), Lewis & Biittiker, 1981, Saudi Arabia), Nadim & Javadian (1976, Iran), Perfil'ev (1968, key with figures for the U.S.S.R.), Theodor (1958, key and figures for the region). The Afrotropical Region: Abonnenc (1972, key with figures), Quate (1964, Sudan). The Oriental Region: Lewis (19786). The Australian Region : papers by Lewis and Dyce are being completed. The taxonomic characters are easily seen in flies mounted in gum-chloral medium which may be ringed with Glyceel (Kevan, 1955: 417, 418; Southey, 1970: 51, 53, 56; Tribe, 1972). Potash was hardly ever used for maceration because it weakens intersegmental membranes and makes specimens difficult to remount. It was occasionally used for treating the tip of the abdomen to clarify the spermathecae although it may distort the ducts. The characters used are described by Abonnenc (1972), Artemiev (1978: 1-8), Forattini (1973), Lewis (1973; 19786: 219), Perfil'ev (1968), Theodor (1958), Young (1979: 5-8) and many others. Lewis's (1973) account is being amplified to include recently introduced characters, some of which are mentioned below. Head length may be measured from the tip of the clypeus to the most posterior parts of the head, and eye length to include the fore and hind facets. The inter-ocular suture is of some use, but mainly for American species. The inter-arcal area lies between the cibarial chitinous arch and the cibarial teeth. The labrum is measured to include the anterior sensilla. The antennal papillae (Parrot, 1953) were discussed by Wirth & Navai (1978 : fig. 5, 47). The dental depth is the distance from the tip of the maxilla to the most proximal tooth. The relative lengths of various leg segments have been used for classification in several groups of insects, including Lepidoptera (Imms, 1964: 555, 556), aphids (Eastop, 1972: 173), Culicidae (Reid, 1953: 75), Ceratopogonidae (Wirth et al, 1977: 621), Chironomidae (Pinder, 1978: 11, 19; Saether, 1976), Mycetophilidae (Hutson & Kidd, 1975: 29; Hutson et al, 1980: 42), Cecidomy- iidae (Panelius, 1965: 5, 132), and Phoridae (Borgmeier, 1964; Schmitz, 1957: 431, couplet 8; THE GENUS PHLEBOTOMUS 123 1958). For the Phlebotominae, Franga (1919: 125) pointed out that leg-segment lengths of each of the species then known varied within narrow limits, and since then many authors have recorded the actual lengths of several or a few segments, mainly in species of Lutzomyia. French writers have measured the hind leg of many species. Raynal (1934: 350) indicated the value of the hind tibia-femur ratio for separating two species of Phlebotomus, and Zariquiey (1937: 417) used the lengths of basitarsus 1 (longer or shorter than femur 1) and of all tibiae of certain species of Phlebotomus. Theodor (1958: 4) remarked that the legs were particularly short in Palaearctic Sergentomyia, Artemiev (1978: 4) referred to various measurements of the hind leg, and Young (1979: 7) mentioned tibia length in Lutzomyia. L. W. Quate often recorded leg measurements regardless of sex, implying that the sexes are similar in this respect, and other publications indicate that differences are usually small. In recent years some authors have recorded lengths of leg segments but not always the same ones, some have ceased to make such records, and others have never done so. It is now time to appraise the value of leg characters and of the time spent in measuring them. In the present work, therefore, the lengths of the long segments of each leg, of females when possible, are recorded in a way to allow quick comparison of species. The legs were measured at x 60, with occasional use of x 120 to locate extensions into preceding segments, which were included. Legs detached from the body could usually be recognized as first, second or third because tibia 2 is nearly always longer than 1, and 3 than 2. All lengths are expressed in units of which 100 are the length of femur 1 of a particular species, and the relative lengths of the nine long segments of one side, usually of one fly, are followed by the actual length in mm of femur 1, and of the wing in some cases. Leg diagrams, first drawn on the scale of one unit to one centimetre (examples in Figs 1 5-24) are useful for comparing species and picking out features of individual species for additional measurements. The aedeagus comprises two side pieces fused at the base (Perfil'ev, 1968: 32, 42) and protects the tips of the sperm tubes. According to Theodor (1958: 5) these tubes are the true aedeagus, and the 'aedeagus' strictly speaking is the aedeagus sheath. Some authors have recorded the length of the aedeagus but without indicating the basal point from which it was measured. The most convenient point is usually the dorsal hind end near the bases of the coxites, and if other points are used in certain cases they can be indicated. The last abdominal segment or proctiger of male sandflies is the ninth (Just, 1973: 314, 315, 316, 332) and shows some specific differences. Isaev (1935: 98) noted three types, in P. papatasi, in P. sergenti and a species of Sergentomyia, and in P. chinensis, characterized by the length of the surstyles, the nature of their junction to the segment, and the ventral shape of the latter. Appreci- able differences are shown by the six species illustrated in Figs 8 to 14. Surstyle is a convenient name for the lateral lobes of the ninth tergite. Keys to the subgenera and their species are provided and should be used in conjunction with descriptions. Taxonomic citations serve as a guide to literature on the genus, subgenera, species and subspecies. Distribution lists of all species show the sources of information for the maps. References to disease transmission by known or possible vector species show many which are or may be important, and indicate publications on biology as well as disease. For some species full lists of taxonomic citations would be unduly complex and long, and early references are confined to a few of historic interest. Where the original or later depository of a holotype, syntypes or other type-material is not shown by a describer, later author or other source, it is deduced (with a query) either from the original paper or another publication which is indicated. Some syntypes have been located with the aid of Abonnenc (1972) although he refers to them as holotypes. Information about the depositories of some types from Afghanistan is given by Artemiev (1978: 23). Types of species described by Professor O. Theodor were kept in the Hadassah Hebrew University Medical School, Jerusalem, until the collection was purchased from the University by the British Museum (Natural History) in 1981. Distribution data, on which the maps are based, are of three kinds, viz. information about types, publications which give detailed information and often earlier references, and previously unpublished records indicated by collectors' initials or 'BMNH'. 124 D. J. LEWIS Some Chinese records were not available when this work was being prepared, and are being assembled for publication by Professor Leng Y.-j. They include the description of 'P. major wui\ for which a preliminary note is included below under P. major, and records of P. longiductus from Xinjiang (Wu etal., 1979). Fossil Phlebotominae It is appropriate to consider the fossils of Phlebotominae and their ancestors because they help to explain the relation of Phlebotomus to other genera and to the evolution of leishmaniasis. Leish- mania probably arose from a monoxenic flagellate parasite of the ancestors of sandflies, so there is likely to be a phylogenetic relationship between the leishmaniae and their vectors (Saf yanova, 19776:281). The hopping flight of sandflies doubtless caused many to be trapped in resin, and some excellent fossil specimens have survived in several of the sources of insects in amber (Hennig, 1973: 6). Their approximate ages in MYA (millions of years ago) quoted below were supplied by Dr P. E. S. Whalley or taken from the British Museum (Natural History) (1972) time scale, Riek (1970) or the work of Smith & Briden (1977) which was also consulted for continental move- ments. Wings of the following species are illustrated (Figs 20-33) to give an impression of the groups mentioned here and later: Permotipula patricia Tillyard, 1929: 779 (Rohdendorf, 1974: 6), Phlebotomites brevifilis Hennig, 1972: 40, 62, Phlebotomus tipuliformis Meunier (Fig. 27 after Hennig), Warileya nigrosacculus Fairchild & Hertig, P. (Spelaeophlebotomus) minteri, P. (Idio- phlebotomus) frondifer, Lutzomyia paterna (Quate, 1963), Brumptomyia galindoi (Fairchild & Hertig), P. (Paraphlebotomus) sergenti, Lu. (Dampfomyia) permira (Fairchild & Hertig), Sergen- tomyia (Neophlebotomus) gombaki (Lewis & Wharton), S. (Sergentomyia) bedfordi (Newstead), S. (Sergentomyia)fallax (Parrot) and S. (Parvidens) lesleyae (Lewis & Kirk). 370 MY A, Devonian The earliest known insect, a wingless form, was living about this time (Riek, 1970: 168). 230 MYA, Upper Permian The mecopteran Permotipula exemplifies a primitive wing to which that of Nemopalpus Mac- quart, though unrelated (Rohdendorf, 1974: 6), is remarkably similar. Nemopalpus is probably among the most primitive living Diptera, close to the basic stock of the Psychodidae and to the Phlebotominae in the matter of venation (Fairchild, 1955: 182; Lewis et al., 1977: 323). The original Diptera, present at this period, were probably biting flies feeding on insects or vertebrates and contemporaneous with the beginning of the reptile age, when the theromorph ancestors of mammals existed before the origin of birds (Downes, 1971 : 241, 261, 262). 220 MY A, Lower Triassic The infraorder Dictyodipteromorpha of the dipterous suborder Archidiptera was probably in existence; it flourished in the Upper Triassic and was apparently the ancestral group which gave rise to two branches, the infraorder Tipulimorpha Rohdendorf and all other later Diptera (Roh- dendorf, 1974: 27, 55, 129, 136, 289, 329). 760 MYA, Middle Jurassic The Tipulimorpha were established (Rohdendorf, 1974: 3, 291, 292) and included the tipulid family Tanydophryneidae Rohdendorf which appears to have been ancestral to 'superfamily' Psychodidea [fossil Psychodidae] (Rohdendorf, 1974: 3, 53, 219, 228, 291-293). This ancient group, distinguished from all other Tipulimorpha by primitive larval features, has retained a complex wing venation but its members have become smaller and thus been able to colonize microhabitats (Rohdendorf, 1974: 53, 58, 292). Before the end of the Jurassic the ancient group of the Phlebotominae, among the smallest of Diptera, must have come into existence (Hennig, 1972: 38, 55, 58), in which the origin of R2 + 3 has been displaced towards the wing tip so that the vein seems to come from /?4, and R2 has been reduced (Hennig, 1969: 385). R2 + 3 is usually branched only in the most primitive Diptera (Colless & McAlpine, 1970: 664). Hennig's important 1972 paper was probably based largely on previous work unpublished owing to the second world war (Schlee, 1978:382). THE GENUS PHLEBOTOMUS 125 720 MY A, Lower Cretaceous The first known two species of Phlebotominae existed in what is now the Lebanon and was south of the Tethys Sea (Hennig, 1972: 38; Melville, 1967: 293). The small, evidently primitive Phleb- otomites longifilis Hennig, 1972: 40, 62, and Phlebotomites brevifilis Hennig, 1972: 40, 62 (Stuckenberg, 1975: 459), had wings with a broad distal half and broadly rounded tip which may have accounted for a displacement of the origin of R2 + 3 beyond that of/?5 (Hennig, 1972: 8, 27, 39, 43, 51). Although these species show few very striking differences from some recent forms they were included in a new genus because close relationship to Phlebotomus was not indicated. Hennig (1972: 21, 28) considered that they might belong to the ancestral group of the Phleb- otominae or to his probably monophyletic 'Phlebotominae s. str.' which comprises Phlebotomus, Sergentomyia, Brumptomyia and Lutzomyia. Stuckenberg drew attention to the short palpal segment 5 of Phlebotomites brevifilis which is like that of some American sandflies. The two Cretaceous species and the present-day Neotropical Warileya have a similar type of wing struc- ture and may be the sole remnants of an early movement from Africa to South America or vice versa across a south Atlantic connection in the Lower Cretaceous or earlier (Hennig, 1972: 38, 39, 44). 30 MY A, probably Upper Eocene One poorly described species is known from Baltic amber (Rohdendorf, 1974: 275), P. (Phleb- otomiella) tipuliformis Meunier, 19056 [as P. tipuliformis]; 1906: 103 [as Phlebotomiella tipuli- formis']; 1912: 71 [as P. (Phlebotomiella) tipuliformis'] (Fairchild, 1955: 183-187; Hennig, 1972: 51-55; Stuckenberg, 1975) and may have lived in the amber forest and fed on thin-skinned reptiles (Larsson, 1978: 92, 93). Hennig regarded it as a member of his Phlebotominae s. str. and perhaps of genus Phlebotomus and of subgenus Euphlebotomus or Anaphlebotomus, which showed that splitting of the ancient Phlebotominae was already far advanced. Stuckenberg referred to the short palpal segment 5 and primitive wing of P. tipuliformis and considered it to be congeneric with Phlebotomites and somewhat intermediate between it and 'Phlebotominae s. str.\ 26 M YA, Miocene Lu. paterna (Quate, 1963: 114) (Hennig, 1972: 56, 59, 62, fig. 41) is the first known phlebotomine with a narrow wing and is related to living reptile-feeding species. One M YA to the present day Philaematus pungens Loew, 1845: 8 (Parrot, 1951 : 28; Duckhouse & Lewis, 1980: 99) from copal of unknown origin, ' Phlebotomus pungens' Meunier, 1905a: 209 (Duckhouse & Lewis, 1980: 99) from Zanzibar copal, and S. succini (Stuckenberg, 1975: 456) (Lewis et al., 1977: 326; Duckhouse & Lewis, 1980: 105) from copal, possibly East African, may be less than one MYA and represent living species of Sergentomyia. Several specimens from African copal examined proved to belong to this genus, and one, treated with xylol and mounted in Euparal, clearly shows pharyngeal teeth, antennal ascoids and palpal sensilla. Distribution Quate (1962: 169, 170) regarded the Phlebotominae as tropical with northern intrusions. Sandflies occupy most of the Old World other than cold regions and oceanic islands, and they are absent from the Seychelles (Scott, 1933: 369), and Phlebotomus from Madagascar (Brygoo, 1974). Sandflies are considered to need at least 50 days a year with a temperature not less than 20°C (Perfil'ev, 1968: 98). Map 1, showing the general distribution of the subfamily in the Old World, is based on data cited by Lewis (1974) and Leger & Rodhain (1978). In western Europe P. per- niciosus and P. mascittii occur about as far north as 49°N, and in Asia P. chinensis is the most northerly species (Perfil'ev, 1968: 89), reaching about 48°N (Beklemishev & Dolmatova, 1948: 354). In Canada sandflies are known from about 50°39'N near Kamloops, from 49°39'N at Coulee Creek in Alberta, and at 44°41'N near Ottawa. The southern boundary of sandflies in the Old and New Worlds is about 40°S (Perfil'ev, 1968: 90). The maps illustrate a mainly northern distribution of Phlebotomus, which is discussed later. It is exemplified by the northern distri- bution of Larroussius, and therefore of kala-azar, in Tunisia (Croset et al, 1978: 744), and by the 126 D J. LEWIS presence of five Phlebotomus species out of six Phlebotominae in France, and two out of 26 in Zaire (Vattier & Bimangou, 1974: 92; Vattier & Trouillet, 1975: 2; 1978: 701). Some 35 species, including P. orientalis, have marked eastern or western limits. Biology Numerous publications dealing with this extensive subject may be located by reference to Abon- nenc (1972), Lewis (1973; 1974a; 1977; 1978a; 19786), Perfil'ev (1968) and others, and notes on various species in the present work. The following brief note refers to a few aspects. Sandfly larvae are difficult to find and many live in soil or burrows of animals. Development from egg to adult takes weeks or months according to temperature, and larvae undergo diapause in some northern and other areas. Many adults of both sexes feed on sugar and the females take vertebrate blood. Adults are active at night and rest in various shelters by day. Movement varies from short hops to flights of a few hundred metres and occasionally nearly 2 km, and is usually stopped by moderate wind. Palaearctic species tend to have one or two generations a year, and some tropical ones flourish in either the dry or the wet season. The genus Phlebotomus includes all the habitual mammal-biters and therefore all the sandfly vectors of human disease in the Old World. Relation to disease The following summary of relation to disease in the Old World is supplemented by notes on some species. The leishmaniases are the main group of sandfly-borne vertebrate infections. It seems probable that Leishmania Ross, 1903; Wenyon, 1926: 396, having arisen as an insect parasite, came to infect reptiles and eventually mammals (Lewis, 19780: 94; Telford, 1979: 322; Wilson & Southgate, 1979: 243), so that sandflies may be regarded as the primary hosts (Lainson & Shaw, 1979: 2). This phylogenetic priority is not only of historical interest for it is reflected in present- day associations which have a practical significance. Lizard leishmanias now occurs in the Old World and possibly in the New World (Lainson & Shaw, 1979: 34). No Leishmania is known in birds (Adler, 1964:42). Many forms of Leishmania are transmitted among mammals by species of Phlebotomus. Basi- cally, each causes a zoonosis into which man may enter to a varying extent, so that human involvement ranges from sporadic cases to a purely man-sandfly infection. Probably in Asia leishmaniae caused enzootics in canids and rodents which led to certain anthroponotic forms which spread to some other Palaearctic areas (Garnham, 1971 : 482, 488; 1977: 18; Hoogstraal & Heyneman, 1969: 1185; Lysenko, 1971: 515-518). The forms of Leishmania are now being classified by means of objective biochemical, serologi- cal and other studies of their intrinsic characters (Chance, 1979; Chance et al, 1977; Garnham, 1976: 536; Lumsden, 1977: 47; de Raadt, 1977: 314; Taqi & Evans, 1978: 56; Williams & Coelho, 1978; Zuckerman & Lainson, 1977: 89), and many forms will probably be recognized. For a long time the leishmaniae were grouped, according to their normal (Lainson & Shaw, 1971 : 21) effect on the (secondary) human host, into visceral leishmaniasis (VL) or kala-azar and cutaneous or dermal leishmaniasis (CL) which causes oriental sore and other diseases. This grouping is unsatisfactory (Chance et al., 1977: 53, 56) but, despite rapidly changing concepts, is still of some practical value. It is used here, where the taxonomic names of the parasites are taken mainly from Lumsden (1977a: 46, 49; 19776). VL is caused by forms of the Le. donovani (Laveran & Mesnil, 19030; 19036: 958) complex which occur largely in wild Canidae and are transmitted mainly by species of the subgenera Larroussius and Adlerius. The anthroponotic leishmaniasis of eastern India is due to Le. d. donovani which has no dog or other animal reservoir and is transmitted by a species of Euphlebo- tomus. Le. d. infantum Nicole, 1908, probably spread from Asia via Transcaucasia into the Mediterranean area where it attacks dogs and children rather than adults. VL probably spread eastwards via the Gobi Desert to eastern China (Beklemishev & Dolmatova, 1948: 351). The east African VL is transmitted by a species of Synphlebotomus, and may infect animals as secondary hosts (Lysenko, 1971: 518). CL is due largely to members of the Le. tropica (Wright, 1903) group. The wild hosts, if any, are usually rodents, and most of the sandfly vectors belong to the subgenera Phlebotomus and THE GENUS PHLEBOTOMUS 127 Paraphlebotomus. Le. t. major Yakimov: 1915: 501; Zuckerman & Lainson, 1977: 67 occurs largely in central Asia (Lysenko, 1971: 518; Lysenko & Belaev, 1977: 250, map) where it infects Rhombomys opimus Lichtenstein, 1823, and some other rodents, and causes 'moist sore' in man. Le. t. tropica (= minor Yakimov) was possibly derived (Hoogstraal & Heyneman, 1969: 1184) from Le. t. major, occurs from the Mediterranean area to India (Lysenko, 1971 : 58), is largely urban, causes 'dry sore' in man and infects dogs. Le. aethiopica Bray, Ashford & Bray is a hyrax parasite which causes disseminated CL in Ethiopia and is transmitted by a species of Larroussius. VL and CL usually occur in different areas (Lysenko, 1971 : 518, 519; Lysenko & Beliaev, 1977: 250; Theodor, 1964: 487), largely owing to the distribution of their vectors. The recognition of a vector is a complex process involving many subjects which include sandfly taxonomy, distribution, host choice and other aspects of ecology, determination of flagellates found in wild flies, development of leishmaniae ingested by flies in the laboratory, and experimen- tal transmission. Proof that a species is a vector can seldom be obtained, and it applies only to a particular place and time; de Raadt (1977: 314) pointed out that detailed study of epidemiology only gives an instantaneous reflection of a process continuing over a long period. The significance of a vector may alter (Lysenko & Beliaev, 1977ft: 263; Sergiev, 1977: 283). There are many gradations from occasional to habitual minor and major vectors. It is therefore impossible to draw up a simple list of vectors, but a list of vectors and suspected vectors is of some value, especially if followed by a summary of the evidence related to each species. In the present work this is confined to references to the literature. Killick-Kendrick (1978: 299, 300) listed 52 taxa, 28 of them Old World form, of Phlebotomus, known or suspected of being vectors of leishmaniasis. The Old World taxa, listed in relation to types of the disease in man are : visceral (Synphlebotomus) celiae, martini, vansomerenae, (Larrouss- ius) ariasi, kandelakii kandelakii, longicuspis, major s. 1., orientalis, perniciosus perniciosus, tobbi, (Adlerius) chinensis chinensis, ch. halepensis, longiductus, simici, (Euphlebotomus) argentipes; cu- taneous (with four marked '+ VL?' which may transmit kala-azar locally): P. (Phlebotomus) bergeroti, duboscqi, papatasi (+ VL?), salehi, (Paraphlebotomus) alexandri, caucasicus (+ VL?), chabaudi, mongolensis ( + VL?), sergenti sergenti, (Synphlebotomus) ansarii, (Larroussius) longipes, pedifer, perfiliewi ( + VL?). P. rossi is a recent suspect. In addition to known vectors some sandflies presumably transmit VL among animals in large areas of Africa where the human disease occurs but is rare (Gigade, 1978: 239), and in part of the Sudan (Hoogstraal & Heyneman, 1969: 1141) and elsewhere where the infection is present with no apparent vector. Many apsects of vectors have been discussed by Adler (1964: 48, 80), Bray (1974: 91), Hoog- straal & Heyneman (1969), Killick-Kendrick (1978; 1979), Lewis (1971; 1974; 19780), Minter (1972), Molyneux (1977: 43-53), Safyanova (1967), Sergiev (1967: 26; 1979) and Williams & Coelho(1978). Sandfly fever virus, transmitted by P. papatasi and possibly other species (PerfiFev, 1968: 128), occurs mainly in the Mediterranean area. Most vector species are difficult, and some impossible, to control. Domestic species were largely controlled by house-spraying against malaria vectors but have increased where this has been stopped, in India, for instance, and in Greece where VL and CL increased when mosquito- spraying ceased (Leger et al., 1979: 12). Sandflies have shown little resistance to insecticides (Killick-Kendrick, 1978: 304) till recent instances in India.
