Distribution. China (Xizang), India?.

Supplementary description. Female. Similar to males, but head slightly convex on dorsum, head width across eyes distinctly narrower than pronotum, antennae shorter and extending to elytral midlength, pronotum wider, about 1.23 times as wide as long, moderately convex on posterolateral parts of disc, elytra with lateral margins distinctly diverging posteriorly, abdominal sternite VIII (Fig. 12) abruptly narrowed posteriorly, nearly parallel-sided on posterior part, longitudinally and narrowly convex in middle of sclerotized part, the convex narrowed posteriorly and acute at apex, with lateral margins nearly membranous, posterior margin roundly emarginated in middle, lateroapical angles rounded, the lobe slightly sclerotized, triangular and acute at apex.

Body length: 6.0‒7.0 mm; width: 1.5‒1.6 mm.

Remarks. The female is discovered and reported for the first time, so a supplementary description is given of the characters different from the male. What’s noted, in the original publication, the type locality of this species is recorded in India, but actually lies in a controversial area between China (Xizang) and India, as seen in Fig. 42 .
