New data on Sciapodinae (Diptera: Dolichopodidae) with a revised catalogue and keys to Afrotropical species of the subfamily

by Igor Ya. Grichanov

Abstract.

Holotypes of 55 species and paratypes of additional 5 species have been examined mainly from the collections of the Royal Institute for Natural Sciences (Brussels) and Royal Museum for Central Africa (Tervuren). Descriptions of 18 new species, new records for known African species are given, 15 species are replaced, several species are excluded from the fauna of Madagascar, Congo (Kinshasa) or even Africa. Subgenus Bickeliolus Grichanov is raised to genus. The following pairs of species are synonymized: Bickeliolus haemorhoidalis (Becker) [(=B. coalescens (Parent)], Chrysosoma consentium Curran (=C. fortunatum Parent), C. katangense Curran (=C. speciosum Parent), C. mesotrichum Bezzi (=C. garambaense Vanschuytbroeck), C. singulare Parent (=C. gracile Vanschuytbroeck), Ethiosciapus bicalcaratus (Parent) [=E. setifrons (Parent)], E. finitimus (Parent) (=E. skufjini Grichanov), Plagiozopelma pallidicorne (Curran) [=P. lindneri (Vanschuytbroeck)]. A revised catalogue and keys to 12 genera and 205 Afrotropical species of Sciapodinae are also presented.

Key words: Diptera, Dolichopodidae, Sciapodinae, nomenclature, Tropical Africa.

Introduction

The last catalogue of Afrotropical dolichopodid fauna (Dyte and Smith, 1980) included about 180 species belonging to 8 genera of Sciapodinae, of which 3 genera were later synonymized, status of 1 genus was changed, and all species of the genus Sciapus were transferred to other genera. As a result, only 65 previously known Afrotropical species are placed now in the sciapodine genera sensu Dyte and Smith (1980). Bickel (1994a) recently revised the world fauna of sciapodine genera. In his big work he proposed 21 valid genera, of which 8 occur in Afrotropical Region. Grichanov (1995–1997) reviewed all African sciapodine genera, described two new genera and 22 new species of the subfamily from the Region. In this paper one new genus is established and one more is recorded for Africa for the first time. Now twelve genera are known from Afrotropical zoogeographical Region, of which Ethiosciapus, Bickeliolus and Gigantosciapus are endemic for Continental Africa and Madagascar, and Bickelia and Mascaromyia are confined to western Indian Ocean islands. Dytomyia was found on Madagascar and in Australia. The number of Afrotropical species belonging to sciapodine genera are as follows: Chrysosoma (67), Amblypsilopus (43), Mascaromyia (21), Plagiozopelma (17), Condylostylus (15), Gigantosciapus (13), Ethiosciapus (10), Bickeliolus (7), Mesorhaga (5), Dytomyia (3), Bickelia (3) and Sciapus (1).

In total, 205 Afrotropical species are known today. Many of those species were briefly or incompletely described. Some of them are known from females, others from males only. Authors in their descriptions often omitted important characters regarded now as having generic level value. That is why no less than 20 species are waiting to be synonymized or be declared Nomina Dubia in future revisions of type material. A few dozens of species are probably waiting to be described. The major fraction of Afrotropical species was described by O. Parent (71 species including 7 placed in synonymy), I.Ya. Grichanov (41 and 1), C.H. Curran (37 and 7), Th. Becker (21 and 2), P. Vanschuytbroeck (15 and 3) and C.G. Lamb (9).

The well-known fauna of Congo (Kinshasa) comprises 84 species; Tanzania numbers 25, South Africa 22, Uganda 20, Nigeria 19, Kenya and Cameroons – 16 species each. Adjacent African islands are poorly studied. Only 29 species were recorded from Madagascar, 16 from Mauritius and 11 from Seychelles. The most interest distribution of species are as follows: Chrysosoma snelli Curran – Tanzania, Kenya, Madagascar, Seychelles, Reunion, Mauritius, Rodriguez, Aldabra, Maldives, Chagos Archipelago; Mascaromyia librativertex (Lamb) – Seychelles, Mauritius, Chagos Archipelago; Bickelia subparallela Grichanov – Chagos Archipelago, Seychelles; Amblypsilopus munroi (Curran) – South Africa, Namibia, Angola, Mozambique, Sri Lanka; Amblypsilopus pallidicornis (Grimshaw) – Madagascar, Seychelles, Hawaiian Islands, Society Islands, Marquesas Islands, Guam, Belau and Taiwan.

Treating material from the collections of the Royal Institute for Natural Sciences [RINS] (Brussels), Royal Museum for Central Africa [RMCA] (Tervuren) and National Museum of Kenya [NMK] (Nairobi), I found a lot of interesting material in the subfamily Sciapodinae. Holotypes of 55 species and paratypes of additional 5 species were examined. In this paper descriptions of 18 new species, new records for known African species are given, 8 species are synonymized and 15 species are replaced, and some previous species records from Madagascar, Congo (Kinshasa) or even all Africa are shown to be incorrect. A revised catalogue and keys to all Afrotropical sciapodine species is also presented.

Holotypes and paratypes of the new species are deposited in the Royal Institute for Natural Sciences (Brussels). Hypopygii removed from the dry specimens are placed after alkalisation into glycerol and mounted on the same pin in a cavity of polymer film covered with a piece of adhesive tape. Most part of the material collected from Madagascar is kept in 70% alcohol inside glass tubes and cans. In addition, one specimen of each species is also placed after alkalisation into glycerol and mounted on pin in sealed plastic container. Listing material examined, I use here slash ( / ) to separate labels on one pin and square brackets [...] to insert my personal remarks. Species diagnosis includes usually key characters and some important features that were missed in original descriptions. Bibliography includes works published after the "Catalogue of the Diptera of the Afrotropical Region" (Dyte and Smith, 1980).

5. Sciapus longimanus Becker

Remark. S. longimanus determined by P. Vanschuytbroeck (female examined, RINS) to be from Madagascar belongs to undescribed species of Amblypsilopus and should be excluded from the fauna of the island. Four females and male (examined, RINS) from Congo (Kinshasa) labelled by the same author as S. longimanus belongs to undescribed or indeterminable species of Amblypsilopus and Condylostylus. So, the species does not occur in the Afrotropical region.

Distribution. Palearctic region.

41. Chrysosoma (Chrysosoma) katangense Curran

Type material examined. Holotypus, ? [red label] / Musee du Congo, Lubumbashi, Mt. Katanga, 1.XI.21, Dr. M. Bequaert / R. Det. D. 1155 / Holotype Chrysosoma katangensis Curran.

Additional type material. Holotypus, ? [red label] / Musee du Congo, Elisabethville, 1927, Dr. M. Bequaert / R. Det. H. 2412 / Chrysosoma speciosum n.sp. Type. O. Parent.

Diagnosis. C. katangense is associated with a group of species having black antenna and numerous long setae on middle tibia and basitarsus. It differs from other species in sinuous vein m-cu, middle basitarsus with four or five long setae and row of shorter setae, half as long as the longest setae; middle tibia with 1 very long apical seta and 3 or 4 long setae, half as long as the longest setae on basitarsus; middle basitarsus dark or yellow, without white preapical ring covered with yellow pectination; second to fifth tarsomeres of middle tarsus without remarkable ciliation; cercus not bifurcated, rounded on apex, with dorsoapical excavation and short pointed apophysis at the middle.

Remark. Holotype of C. speciosum Parent has no difference from holotype of C. katangense Curran.

Distribution. Congo (Kinshasa), Sudan.

43. Chrysosoma (Chrysosoma) leucopogon (Wiedemann)

Remark. I re-examined material including several specimens determined by C.E. Dyte from the Natural History Museum in London (Grichanov, 1997) and collected in Kenya, Tanzania, on Chagos and Maldives. All males strongly differ from C. leucopogon as described by Bickel (1994a) in hypopygium morphology, belonging apparently to C. snelli described and figured accurately by Curran (1927). Long seta on 7th tergite and unequal arms of cercus figured by Lamb (1922) show that his description of C. leucopogon from Seychelles belongs also to C. snelli. Among other authors, only Parent (1934) recorded this species for western Indian Ocean Region (Mauritius).

Distribution. ?Mauritius, ?Aldabra; Chagos Archipelago, Burma, Sri Lanka, Taiwan, India, Indochina, Java, Sumatra, Thailand, Queensland, New Caledonia, Tahiti.
