Redescription. Length 4.5–5.0 mm; oval-elongate, moderately convex, subopaque; more or less widely shortly and densely silver-grey pubescent. Blackish or piceous black; head, pronotum and elytra with margins dark reddish. Head with epistome convex at centre, coarsely and densely punctured, punctures sparser on disc, denser on sides; clypeus feebly sinuate at middle, obtusely angulate at each side, bordered, edge nearly imperceptibly bristled laterally; genae obtuse, rather shortly ciliate, distinctly protruding from the eyes; frontal suture nearly obsolete at middle, moderately raised laterally; front coarsely and rather densely punctured. Pronotum transverse, moderately convex medially, narrowly flattened on sides, strongly and densely punctured, punctures subconfluent on sides; lateral margins with border cerciniform and minutely bristled, slightly inwardly sinuate before hind angles; latter subtruncate; base slightly bisinuate and distinctly bordered. Scutellum with curved sides, coarsely and confusedly punctured. Elytra elongate-oval, moderately convex, not denticulate at shoulder; epipleural carina very distinct at humeral callus and minutely bristled; striae wide, shiny, superficially punctured and subcrenulate discally, indistinctly punctured and canaliculate toward apex; interstices flat with punctation confusedly vermiculose. Upper spur of hind tibiae shorter than first tarsal segment; latter as long as following three segments combined. Male: pronotum relatively more transverse; fore tibiae spur stout, spatulate, and apically hooked; metasternal plate spoon-shaped, punctured and shortly pubescent distally; aedeagus Fig. 9–10 .
