UP to now, no Drosophilid species has been reported from Sichuanprovince, China.We have started a fauna of survey Drosophilid species since 1989.A totalof over 15,000 individuals were collected. In fthe Present work -five new speciesand a new record were described. Two new species of genus MicrodrosophilaMalloch,M.(Oxystyloptera) chuii,- M.(O.) sagittatusa, one new species of thegenus Liodrosophila Duda, Lio. iophaLlanthusa, two new species of the genusDrosophila Fallen,D.(Sophophora) solStitiatis, D. (Drosophila) salpina and onenew record of the genus Scaptomyza Hardy, Sc. clavata Okada.All holotypes and paratypcs are deposited in the institute of Genetics,Fudan University, Shanghai, China.Genus Microdrosophila MallochSubgenus Oxystyloptera Dudasubgenus Oxystyloptera DudaMicrodrosophila (Oxystyloptera) chuii, sp.f nov. brig .l)This new species belongs to MicrodroSophila (OXystyloptera) and rsemblcsM.

But distinguished by aedeagustip pointed, anterior a pair clawas large than to posterior, cercus oblong,apically with about 15 stout black setae, decasternum heart --shaped.Holotypef ac, Mt.

(Fig, 5) This new species belongs to immigrans species --group and resemblesDrosophila (Drosophila) kitagawai J.
