Complementary description to Breuning (1956) and Lin & Jiroux (2011). Integument of body, antennae and legs blackish; elytra reddish ochraceous. Head, pronotum, elytra predominantly covered with bright pubescence which is individually variable from brick-red to pale orange or yellowish white (Figs. 1–3). Ventral surface predominantly covered with fine blackish pubescence, except for anteromedian of prosternum, most of mesanepisternum, posterior angle of metasternum and lateral sides of abdominal ventrite I to V covered with same variably colored pubescence as in dorsal surface. Scutellum moderately pubescent, not obscuring integument, giving it darkened appearance (Figs. 8, 9). Male genitalia with endophallus, in everted condition (Fig. 19), about 2.3 times as long as median lobe, curved near apical fourth dorsally; APH defined, BPH and MPH roughly defined by basal-lateral tubercle (blt); crescent-shaped sclerite absent; MPH subdivided into MT+CT and PB by constrictions, MT ca. 1.5 times longer than CT or PB; MT with ventral swelling (vs) generally rudimentary; CT with lateral tubercles (ltc, Fig. 19d) weakly developed; PB weakly swollen laterally and ventrally near base, thence, in ventral view, strongly constricted toward subparallel-sided apex (Fig. 19d); APH not subdivided, in lateral view, moderately swollen, slightly protruding ventrally; apical furrow (af) with internal membrane (im) incomplete, represented by short dorsal appendix; spicules mainly distributed on ventral apical surface of MT and apical half of PB; ejaculatory ducts (ej) paired, gonopore (gn) situated near apex of dorsal side of APH. Female with ventrite V (Fig. 15) narrowly protruded, apex 0.13 times basal width.
Distribution. China: Yunnan, Xizang (new province record); India: Assam (Mukhopadhyay & Halder 2003), Meghalaya, Sikkim and West Bengal; Bangladesh (Silhet = Sylhet); Myanmar (Kachin, Mandaley), Nepal.
