Diagnosis. Forewing length 16.5–18.5 mm in males and 19.0–20.0 mm in females. This species has two forms, striped one (Figs 21, 22) with blackish suffusion along veins, and typical one (Fig. 20) with transverse lines consisting of short longitudinal blackish dashes on veins. Barsine yuennanensis is very similar externally to B. hausmanni (Figs 17–19) and B. dao (Figs 25–28) and can be distinguished from the latter by slightly paler fore- and hindwing coloration only. Compared to B. hausmanni, it has ciliate male antennae (bipectinate in B. hausmanni), paler coloration, shorter and narrower dashes of transverse lines (longer, broader and more diffuse in B. hausmanni), and the antemedial and medial lines well separated from each other (whereas in B. hausmanni those are connected in the cell). The male and female genitalia of B. yuennanensis (Figs 42, 53) are most similar to those of B. nigrovena (Figs 43, 54) and B. eurydice (Fig. 44). The differences are listed in the diagnosis of B. nigrovena and B. eurydice.

Distribution. China (Yunnan) (DANIEL 1952, FANG 2000). The record from Thailand (ČERNÝ & PINRATANA 2009) belongs to B. hausmanni.
