Redescription. Length 5.0– 5.5 mm; oval-elongate, moderately convex, shiny, glabrous. Piceous, clypeal margin, sides of pronotum and elytra reddish-brown; legs brownish; antennal club blackish. Head with epistome moderately convex, finely and somewhat irregularly punctured, punctation more superficial and confused distally; clypeus faintly sinuate at middle, distinctly denticulate at sides, denticles upturned, lateral margins feebly arcuate, not bordered, glabrous; genae obtuse, rather shortly ciliate, distinctly protruding from the eyes; lateral vestiges of frontal suture only; front somewhat more coarsely and irregularly punctured than epistome. Pronotum moderately transverse, moderately convex, narrowly flattened on sides; dually irregularly punctured, large punctures, three to four times larger than small, denser on sides and toward base, almost lacking anteriorly; small rather fine punctures regularly scat- tered throughout; lateral margins distinctly bordered, feebly inwardly sinuate before hind angles; latter broadly truncate, edge glabrous; basal margin with border widely interrupted at middle but therein crenulate by a contiguous belt of coarse punctures. Scutellum regularly triangular, sparsely punctured on basal half. Elytra elongate, slightly widened posteriorly, distinctly denticulate at shoulder, finely striate; striae rather deep, distinctly punctured; interstriae flat, very finely and sparsely punctured. Hind tibiae upper spur faintly longer than first tarsal segment; latter as long as following three seg- ments combined. Male: head and pronotum relatively less densely punctured; fore tibiae spur short, stout and abruptly downward bent; aedeagus Fig. 34–35 . Female: head and pronotum relatively more densely punctured; fore tibiae apical spur slender and regularly curved.
