[Reports on two species of Pegohylemyia tibetana group in Xiling snow mountain of Dayi county, Sichuan, China (Anthomyiidae, Diptera)].
Male:Body 7mm. in length. Having a pair of bristles on the distal part of cercal plate, a blunt round angle of postgonite, the new species being less related to Pegohylemyia macrospini gera Deng, 1990, but having 4 pairs of large spines on the 5th sternite, a spherical point of postgonite and biconcave surstyli at apex, thus differing from the relative species. Holotype male, paratypes 18 male male, Xiling snow mountain of Dayi county, Sichuan, 17, July 1993, coll. Geng Lin, Deng Anxiao. Male:Body 7mm. in length. Having 4 pairs of spines on the 5th sternite being similar to Pegohylemyia nigribella above, but having legs with yellow color and round apex of surstyli resembling Pegohylemyia setisilva Jin, 1983; however, broadening postgonite and slender surstyli may be distinguished from all yellow leg species in this group. Holotype male:paratypes 63 male male, date and place of collection being the same as the first species above, coll Geng Lin, Li Ling, Deng Anxiao. Holotype and paratypes are kept in author's laboratory.
