Remark: This species is closely related to Drosophila (Drosophila) chamundiensis Sajjan & Krishnamurthy, 1972. 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 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 V’s, a pair of rods, a pair of dots and a J-shaped X chromosome and an equal Y chromosome.

Distribution: Yunnan.
