Description. Length 3.5-4.5 mm; oval, convex, moderately shiny, almost glabrous. Piceous; head distally, pronotum on sides, more or less widely yellowish; elytra yellow with sutural margin and two oblique bands of more or less broadened piceous spots; legs reddish-brown; antennal club dark testaceous. Head with epistome moderately gibbous, distinctly evenly almost densely punctured; clypeus feebly sinuate at middle, widely rounded at sides, thinly bordered, edge glabrous; genae obtusely rounded, shortly ciliate, feebly protruding more than eyes; frontal suture only laterally distinct and somewhat raised; frons evenly distinctly punctured. Pronotum transverse, convex, evenly punctured, the punctures moderately dense, somewhat more sparse and superficial on disc; lateral margins feebly arcuate, thinly bordered, edge glabrous; hind angles obtuse; base feebly bisinuate, thinly bordered, sometimes the border more or less widely interrupted at middle. Elytra oval, strongly convex, superficially alutaceous thus moderately shiny, with a small denticle at humerus; striae moderately impressed, distinctly punctured, crenulate; intervals flat, distinctly finely and sparsely punctured, minutely pubescent on preapical declivity. Hind tibiae superior apical spur shorter than first tarsal segment; latter longer than following two combined.
