Diagnosis. Adult ( Fig. 3 ) wingspan 10.0–12.0 mm. This species is similar to D. mitteri Park, 1994 superficially. It can be distinguished from D. mitteri in the male genitalia by having sicae with the left lobe longer than the right lobe and only the left lobe having ventral carinae, the aedeagus with a strong cornutus ( Fig. 16 ), and in the female genitalia by the corpus bursae with a sclerotized helical lobe ( Fig. 27 ). In D. mitteri , both lobes of the sicae are equal in length and have ventral carinae, the cornutus is absent in the aedeagus, and the corpus bursae has no sclerotized helical lobe ( Park, 1994: 17, Fig. 8 : a, b, c, Pl. II-11).

Distribution. Cambodia (Mondul Kili), China (Guangdong, Hainan, Hong Kong, Taiwan, Yunnan).
