Redescription. Length: 11.8–12.7 mm, length of elytra: 9.1–9.4 mm, width: 7.1–8.1 mm. Body oval, reddish to dark brown, dorsal surface dull, labroclypeus, tibiae and tarsi shiny, nearly glabrous except lateral setae of pronotum and elytra and a few setae on head.

Labroclypeus transversal, trapezoidal, widest at base, lateral margins straight and moderately convergent anteriorly, producing an indistinct, blunt angle with ocular canthus, not incised laterally before labrum, anterior angles strongly convex, anterior margin straight, margins weakly reflexed; surface weakly convex medially, densely, rugosely and very coarsely punctate, distance between punctures smaller their diameter, punctures partly fused with each other and intermixed with numerous very large punctures bearing each a robust erect seta. Frontoclypeal suture finely incised, weakly curved; smooth area in front of eyes 1.5 times as wide as long; ocular canthus very short and wide, very finely and densely punctate, with a short terminal seta. Frons finely and sparsely punctate, in posterior half with a densely punctate stripe being densely setose as beside eyes. Eyes small, ratio diameter/ interocular width: 0.5. Antenna with ten antennomeres, club with antennomeres, in male slightly longer than the remaining antennomeres combined, in female distinctly shorter than the remaining antennomeres combined. Mentum convexly elevated, flattened anteriorly.

Pronotum wide and moderately convex, widest at base, lateral margins evenly moderately curved and convergent anteriorly, anterior angles sharp and distinctly produce, posterior angles moderately rounded, lateral margins immediately beside anterior angles slightly concavely emarginate; anterior margin with fine marginal line, slightly convexly produced medially; surface with fine, sparse to moderately dense puncture, with indistinct microscopic setae in punctures, anterior and lateral margins with sparse and moderately long setae. Scutellum widely triangular, punctation as in pronotum, on midline punctures less dense.

Elytra widest at middle, external apical angles widely rounded, striae finely impressed, finely and densely punctate, intervals flat, finely and sparsely punctate, odd intervals partly with single short more or less erect setae, humerus close to epipleural margin with a single long seta; epipleural margin moderately robust ending at external apical angle; epipleura finely and densely setose; apical margin chitinous, without a rim of microtrichomes.

Ventral face coarsely and densely punctate, moderately densely setose; mesosternum between mesocoxae slightly wider than the mesofemur. Metacoxa glabrous, laterally with a few robust setae. Ratio of length of metepisternum/ metacoxa: 1/ 1.72. Abdominal sternites dull, finely sparsely punctate, with a row of robust punctures each bearing a short robust seta, penultimate sternite with a broad shiny and chitinous rim being half as long as sternite. Pygidium apically in male strongly convex, coarsely and densely punctate, punctures less dense basally, with microscopic setae in punctures, with a few long robust setae at apex, in female pygidium weakly convex.

Legs moderately long and wide; femora finely and sparsely punctate, with two longitudinal rows of setae. Metafemur moderately shiny, anterior margin acute, without adjacent serrated line; posterior ventral margin almost straight, weakly widened in apical half, neither ventrally nor dorsally serrated but smooth, glabrous. Metatibia moderately long and wide, sides subparallel, basally slightly narrowed, ratio width/ length: 1/2.63; dorsal margin sharply carinate, with two groups of spines, basal one shortly before the middle, apical one at three quarters of metatibial length, with a few fine robust setae basally; lateral face longitudinally convex, smooth, laterally and basally with sparse and fine punctures; ventral margin with four strong equidistant spines; medial face smooth and glabrous; apex interiorly near tarsal articulation shallowly and concavely emarginate. Tarsi in cross section circular, without lateral carina, metatarsomeres glabrous ventrally, with a strongly serrated carina, subventrally with a second, smooth longitudinal carina; first metatarsomere distinctly shorter than following two tarsomeres combined and one third of its length slightly longer than the dorsal tibial spur. Protibia short, bidentate. All claws symmetrical, feebly curved and long, with normally developed basal tooth.
