Head very finely punctured; labrum yellow, with apical margin curved; clypeus short; with two small reddish-brown spots on frons (Fig. 10); mandibles dark and pointed; eyes elliptical, large; antennae filiform, reddish-brown basally, segments 5th–11th darker. Prothorax bluish-black (LP = 1.1 mm), finely and evenly punctured, transverse, maximum pronotal width at base (WP = 2.5 mm); with lateral sides margined and narrow margins apically and basally; anterior angles produced and acute, posterior angles pointed. Scutellum triangular, bluish-black (reddish in some individuals). Elytra bluish-black, with two large reddish-brown spots sub-basally behind humeral callus; elongate (LE = 3.5 mm); broader basally than apically with maximum elytral width at basal half (WE = 3.0 mm), sparsely punctate-striate, with intervals finely punctured; humeral callus slightly protruding. Legs reddish-brown to dark brown; hind femora swollen; a small spine at apex of hind tibiae; all tarsi with a pad of setae ventrally.

Measurements of one male: LB = 5.1 mm; LP = 1.0 mm; WP = 2.4 mm; LE = 3.3 mm; WE = 2.9 mm; LA = 1.99 mm; Median lobe of aedeagus in ventral view parallel and narrow basally, venter with oval groove (LA = 1.99 mm) and apically with rounded tip; in lateral view, median lobe curved, (Figs. 24, 25 and 26). Females generally slightly larger than males (measurements of females: LB = 5.5 & 5.6 mm; LP = 1.0 & 1.1 mm; WP = 2.6 & 2.7 mm; LE = 3.6 & 3.8 mm; WE = 3.1 & 3.2 mm; LS = 0.43 mm).
