Tylotrypes Bezzi, 1914 View in CoL ( fig. 10 View Fig )

Type species: Tylotrypes immsi Bezzi, 1914 .

D i a g n o s i s. Robust, densely setulose dark brown flies with darkened wings (fig, 10, 1, 2, 4, 13, 14); head without subocular sclerite; face with ( fig. 10 View Fig , 5 View Fig ) or without carina ( fig. 10 View Fig , 15); wing with straight and entire vein Sc, straight R 2+3, and without a spurious vein, costa more or less thinned posterior of R 4+5 apex; femora without ventral rows of shortened and thickened setae, usually densely setose; femoral organ in females usually lacking, except in T. fuscipes (Wulp) ; scutellum heavily setulose; synsternite 1+2 wide, with setulose posterior part; epandrium setulose dorsally, with moderately short surstyli (medial surstylus without prensisetae); hypandrium with two posterior lobes forming a phallic guide between surstyli ( fig. 10, 10 View Fig , phg); oviscape with long medioventral sclerotized lobe, but without hook- or nail-like unpaired sclerotized process ( fig. 10 View Fig , 6 View Fig , mvl), often with calluses on ventral surface ( fig. 10 View Fig , 2 View Fig , 4 View Fig , 6 View Fig , 14, opc); aculeus with basal part thickened dorsoventrally, but neither Y- or T-shaped ( fig. 10 View Fig , 7 View Fig , 8 View Fig ); three sclerotized sausage-like spermathecae ( fig. 10 View Fig , 9 View Fig ), one of them smaller and shorter.

Tylotrypes shares the absence of the subocular sclerite, and straight veins Sc with Pyrgota Wiedemann and Tephritopyrgota Hendel and apparently is related to them, differing by having very long medioventral lobe of the oviscape apex instead of a short hook and also by the shape of aculeus with its basal part thickened dorso-ventrally and triangular in profile ( fig. 10 View Fig , 7 View Fig , 8 View Fig , a unique character state not occurring elsewhere, possibly a synapomorphy of Tylotrypes ).

R e m a r k s. I have examined about two dozen specimens from Nepal, Thailand, Malaysia, Mainland China, Taiwan, and Indonesia (Java, Borneo), which represent six to eight species of the genus Tylotrypes similar or identical to species described by Shi (1994; 1996) from China (Yunnan) as Apyrgota species. As the type material is unavailable at this moment and illustrations and descriptions are incomplete or based on males alone, identification of that material with Chinese nominal species is pending until a forthcoming revision of Tylotrypes . Judging from the photographs of the type specimen of Apyrgota longa Shi kindly provided by Dr. Li-hua Wong (Beijing) it must be with certainty transferred from Apyrgota to Tylotrypes , which now contains seven nominal species:

Tylotrypes breviventris ( Shi, 1996) (Apyrgota) ( China: Yunnan), comb. n.; Tylotrypes fura ( Shi, 1996) (Apyrgota) ( China: Yunnan), comb. n.; Tylotrypes fuscipes (Wulp, 1885) (Campylocera) ( Indonesia: Java), comb. n.; Tylotrypes immsi Bezzi, 1914 ( India) View in CoL ; Tylotrypes jiangleensis (Shi, 1994) (Apyrgota) ( China: Fujian), comb. n.; Tylotrypes longa ( Shi, 1996) (Apyrgota) ( China: Yunnan), comb. n., and Tylotrypes hispida (Kim & Han, 2001) , comb. n. ( Adapsilia View in CoL ) ( South Korea).

These taxonomic acts are based either on the material examined (to be listed in the forthcoming publication) or on the comparison of the diagnosis of the genus with original descriptions.

Some of these species were described from males and females alone, and can belong to the same species; I do not synonymize them here as it needs study of additional material and will be subject to a taxonomic revision (Korneyev, in preparation).

This paper is partly resulting from the study supported by the Belgian Federal Office for Scientific , Technical and Cultural Affairs Research Fellowship and conducted in the Royal Museum for Central Africa , Tervuren , Belgium in 2005–2006; most type specimens were photographed there. My thanks are due to Ben Brugge ( RMNH), Robert Copeland ( NMKE), Allen L. Norrbom ( USDA SEL, Washington, D. C., U. S. A., material from USNM), David Notton ( BMNH), Thomas Pape ( ZMUC), Peter Sehnal ( NHMW), and Chen W. Young ( CMNH), who kindly put at my disposal important material, both type and undetermined, or provided necessary data on the specimens deposited in collections under their care. Chris Raper kindly read the early proof of this paper. I thank Robert Copeland and an anonymous reviewer for their criticism and valuable comments.
