In this paper, a new species, Drosophila (Drosophila) longisetae Zhang et al, which is closely related to Drosophila chamundiensis Sajjan & Krishnamurthy, 1972, is described from Kunming, China. It differs from the latter in shape of periphallic organs. There are a cluster of bristles at the end of the genital arch, and the clasper is decorated with a row of teeth, 19 or 20 in number, and many bristles. In this new species, the arista is provided with 3 branches above, 1 below, plus the large terminal fork, but in Dr. chamundiensis with 6 branches above, 3 below. The male metaphase plate consists of a pair of V's, a pair of rods, a pair of dots and a J-shaped X chromosome and an equal Y chromosome. Body length: 4.5mm.Female: The external characters of body are similar to male.Holotype (?) , Huahongdong, Kunming, Yunnan. 1985-Ⅸ -13. Coll. Lin Fayao. Allotype (?), ditto. Paratypes 6 (?)
