Diagnosis. Adult (Fig. 6) wingspan 13.0–15.0 mm. This species resembles D. fuscahopa Li & Zheng, 1996 superficially. It can be separated from D. fuscahopa by the forewing having a narrow yellowish brown, jagged, arcuate fascia from 3/4 of costal margin reaching above tornus; in the male genitalia by the sicae separated from base (Fig. 19); and in the female genitalia by the eighth tergite with a sclerotized semicircular plate on the posterior margin (Fig. 29). In D. fuscahopa, the forewing has no fascia, the sicae are fused in basal 1/4, and the eighth tergite has a sclerotized, triangular plate on the posterior margin (Li & Zheng, 1996: 242, Figs 51, 52).

Distribution. Cambodia (Mondul Kili), China (Guizhou, Henan, Hunan, Jiangxi, Shaanxi, Sichuan, Zhejiang).
