Redescription.

Body length 5-10 mm. Body, including legs, black, except brownish red head, antennae, prothorax and scutellum. Brownish red parts sometimes darker brown to black.

Male (Fig. 14). Head rounded, interocular distance 0.75 × as wide as eye diameter; preorbital swelling slightly convex and glabrous; frons distinctly impressed, sparsely and coarsely punctate. Eyes reniform, moderately bulging, genal canthus encroaching to 0.6 × eye width. Antennae (Figs 18-19) surpassing base of elytra when directed backwards, gradually broadening toward apex, antennomere 1 subglobular, 0.3 × as long as distance between antennal insertions, antennomere 2 small, shorter than 1, antennomere 3 longer than 2 but shorter than 4, 5 subquadrate, shorter than 4, 6 longer and wider than 5 and 7, 7 slightly transverse, 8 twice longer than 7, anterior inner angle slightly produced, 9 and 10 strongly transverse, inner anterior angle almost dentiform; inner surface of antennomeres 5 to 10 flattened, smooth, glabrous, bordered with fine carinae; antennomere 11 as long as combined length of 4 preceding antennomeres, as wide as 10, subparallel-sided, strongly concave ventrally, inner margin of concavity bordered with carina forming sharp angulation in basal quarter.

Pronotum moderately transverse, maximum width at middle, anterior and posterior angles rounded; disc with four indistinct transverse lateral impressions; surface coarsely, sparsely and irregularly punctate, punctures separated by interspaces of 0.3 to 1.5 puncture diameter on disc, tending to be subcontiguous toward lateral portions; longitudinal midline with fine, obsolete carina.

Elytra elongate, moderately dilated posteriorly, widest at apical 1/3, about 5 × as long as pronotum; punctation moderately dense, punctures separated by interspaces of 0.5 to 1 puncture diameter; interspaces slightly convex, forming short oblique or transverse wrinkles; dorsal pubescence consisting of long, erect, sparsely set whitish hairs; humeral callosity separated from basal part of disc by distinct impression; elytral margin visible in dorsal view except at humeral callosity; elytral epipleura densely punctate, parallel-sided from base to level of metacoxae, then gradually narrowing towards apex. Mesoventrite, mesepisternum, metepimeron, metepisternum finely and sparsely punctate; metaventrite very finely punctate, almost smooth, punctation becoming denser in lateral portions.

Legs narrow; apical 0.3 of middle and hind femora reaching beyond edge of elytra; fore and middle tibiae nearly straight, slightly shorter than femora, hind tibiae straight, with sparse tuft of short and fine hairs before middle, without visible denticulation. Tarsi simple.

Aedeagus with distal part of basale narrow, gradually attenuating, apicale narrow, pointed (Figs 22-23).

Female (Fig. 15). Larger than male. Head with interocular distance about 1.2 × as wide as eye diameter. Preorbital swelling not developed. Antennomeres not modified, 5 to 10 without flattened and smooth inner surface and produced inner anterior angle; antennomere 9 quadrate, 10 slightly transverse; antennomere 11 not concave, shorter than combined length of 2 preceding antennomeres. Elytra broader and more widening posteriorly. Legs shorter, hind tibiae without sparse tuft.
