Description. Length 9.8–11.7 mm, width 3.2–3.8 mm. Black, head and pronotum with blue luster; elytra with purple luster, and in some specimens mixed with slight blue or green luster; Ant 1 yellow or with apical fourth brown; femora black with blue luster, tibiae yellow. Head equal to or slightly wider than pronotum, HW/PW 5 1.06 (1.00–1.11); Ant 1/Ant 3 5 3.31 (3.07–3.48); labrum with medial lobe slightly or moderately protruded anteriorly; genae short, moderately tumid; eyes large, convex, 2.7 times as long as genae. Pronotum short, PL/PW 5 1.30 (1.25–1.39), widest at apical third. Elytra short, EW/PW 5 2.18 (2.00–2.31), EL/EW 5 1.63 (1.53–1.70), widened posteriad to apical fourth, then slightly narrowed to apex; outer angles broadly rounded ( Fig. 36 ); intervals slightly convex, sparsely punctate, punctures small, mixed with some larger ones. Protarsomere 3 slightly asymmetrical in male; tarsal claws with 4–5 short pectinations, length of the longest pectination less than half width of claw base ( Fig. 68 ). Aedeagus with apical lamella wide, thin, linguiform ( Figs. 79–80 ).

Distribution. Bangadesh, Bhutan, China, India, Myanmar, Nepal, Sikkim, Vietnam.

Remarks. We have not examined the type. Members of this species are readily recognized by their short pronota and purple elytra. They are very similar to D. kulti Jedlicka members, but differ in having purple elytra and more rounded elytral outer angles ( Figs. 35–36 ).
