Stenothemus harmandi species-group

Diagnosis. Antennae filiform and simple in both sexes. Pronotum with posterior angles acute, protruding (Figs. 1‒2, 4‒8) or obtuse, subrounded (Fig. 3). Aedeagus (Figs. 21‒41): ventral process and dorsal plate of each paramere bent ventrally, arcuate in lateral view, ventral process more or less thickened terminally, dorsal plate narrowed apically. Female with abdominal tergite VIII (Figs. 9‒10) curled ventrally on both sides, sternite VIII (Figs. 11‒20) distinctly narrowed posteriorly, presenting with a more or less sclerotized lobe behind the middle emargination of posterior margin.

Distribution. China, India, Nepal.

Remarks. All the species are almost of the same coloration, and are best distinguished from each other by the characters of body-size, pronotum, aedeagus and abdominal sternite VIII of the female.
