Drosophila (Drosophila) medioconstricta Watabe, Zhang et Gan, 1990 

　　Remark: D. medioconstricta is related to D. lacertosa, D. yunnanensis and D. bai in having novasternum with submendian spines, but distinguishable from the latter three species by the shapes of aedeagus and ovipositor. Further, this species seems to be related to the D. melanica and D. virilis species-groups in having a relatively small value of C-index. 

　　Distribution: Yunnan.
