Diagnosis. This species is similar to D. caudapiscis, D. conicollis and D. myanmarensis sp. nov. in appearance. The species can be distinguished from D. caudapiscis and D. myanmarensis sp. nov. by markedly shorter parameres of the male aedeagus. Male aedeagus of D. conicollis possesses similar short parameres, but has paired horn-like sclerites distally, and posterior margin of male sternite VIII is covered by numerous setae. These characters clearly distinguish them from this species.

Distribution. China (Guizhou), India, Thailand, Myanmar.
