摘　　要：记述了果蝇属Drosophila条纹果蝇亚属Dorsilopha1新种,粗齿果蝇Drosophila(Dorsilopha)confertidentatasp.nov.。同时包括条纹果蝇亚属4个物种的分布及检索表。Drosophila Until now, subgenus This paper describes one new species of （ Dorsilopha ） confertidentata sp. nov. there are only three species including in Oorsilopha： Drosophila （ Dorsilopha ） busckii Coquillett, 1901; Drosophila linearidentata Toda, 1986 and Drosophila neobusckii Toda, 1986. It is at the while an enigma about the origin of the single cosmopolitan synanthropic species Drosophila busckii of subgenus Dorsilopha before other two species from Myanmar were described by Toda. The new species found in Kunming of Yunnan Province of China in this paper and the distribution of D. linearidentata and D. neobusckii in south supports Throckmorton＇s part of China much more hypothesis （1975） of an Oriental origin of D. buschii. All the types are deposited in College of Life Sciences, Peking University, Beijing. Drosophila （ Dorsilopha ） confertidentata sp. nov. （Figs. 1-7） Diagnosis. Cercus with ca. 15 stout setae on the caudo-ventral cornor （without such setae in busckii, neobusckii and lineardentata） ; prensisetae of surstylus long and apically pointed, arranged in curve row as mirror shape of letter S. Male terminalia. Epandrium yellow, with ca. 13 bristles from middle to lower portion; pubescent only on the dorsal surface, caudal margin of lower part partly covering surstylus, toe narrowly elongate, sclerotized, curved inward, without bristles. Cercus oval, sparsely pubescent, setigerous. Surstylus slightly rectanglar, with ca. 16 long and pointed prensisetae. Aedeagus slender and elongate, gently curved ventrad, dorso-apically with a pair of sclerotized processes. Paramere fused to hypandrium, with ca. 4 sensilla. Gonopod absent. Hypandrium pubscent apically, with 2 pairs of paramedian spines. Female terminalia. Oviscapt yellow, with ca. 7 lateral and ca. 8 marginal pegs, with 1 subapical ovisensilla.
