Coelomyia tianfuensis Feng,sp. nov.(Fig.1) Male: Body length 4.0mm. This new species is closely related to Coelomyia mollissima Haliday, 1840,but differs from the latter in: Epistoma not much protruding than the frontal angle; haustellum shorter and thicker; male surstyli not plank like but S shaped in lateral view; cercus on both of sides of subapical part not straight but concavely with ones in posterior view.

This new species is closely related to Dichaetomyia palpiaurantiaca Feng,1999,but differs from the latter in: Gena not 1/4 but 1/8, the eye height;fore femur on anteroventral surface of apical part without shorter and thicker bristle;R 4+5 on basal vertral surface bare; male cercus on apical part not thin and sharp but broaden in lateral view. It is also closely related to Dichaetomyia heteromma Emden,1965,but differs from the latter in:Mmatidia of eye not enlarged distinctly on up mid part;squamopleura hairy;postalar declivity bare; fore ia absent. Female: Unknown. Holotpe ♂,Mingshan(Mt.Meng,1452m;30°03′N, 103°01′E),Sichuan Prov.,China, IV.1989.Coll.by Feng Yan. 4.Paradichosia xibuica Feng, sp.nov. (Fig.4) Male: Body length 6.0 mm. This new species is closely related to Paradichosia scutellata Senior White, 1923, but differs from the latter in: Fore femur not black but yellow; 3rd sternite on postmargin with hairs in cluster about 0.7 time as long as this ventral segment; male cercus on both of sides of subapical part not inward concave but straight in posterior view; paraphallus on apical part not blunt angle with carve but straight in lateral view. Female: Unknown. Holotype ♂, Mt. Erlang(Forest Farm, 2460m; 29°54′N, 102°08′E), Sichuan, Prov., China, 16. VIII. 1980. Coll. by Feng Yan.
