Brownish; clypeal margin, pronotum sides, base and preapical declivity of elytra yellowish; legs brownish; antennal club dark testaceous. Head with epistome weakly convex on disc, rather finely, regularly, not densely punctured; clypeus almost semicircular, anteriorly faintly truncate, finely bordered, edge with extremely short and sparse bristles; genae round, very shortly ciliate, not protruding from the eyes; frontal suture finely impressed; front finely, regularly punctured. Pronotum transverse, moderately convex, dually, somewhat irregularly punctured; punctation coarser and denser on sides; large punctures, twice larger than small ones, missing on disc; small punctures almost regularly sparse throughout, more superficial on disc; lateral margins feebly arcuate, distinctly bordered, edge glabrous; hind angles truncate; truncature not sinuate inwardly; base bisinuate. Scutellum elongately triangular, sparsely irregularly punctured on basal half. Elytra oval-elongate, minutely denticulate at shoulder; striae fine, superficially punctured, subcrenulate; interstriae feebly convex, very finely sparsely punctured. Hind tibiae upper spur somewhat longer than half of first tarsal segment; first tarsal segment as long as following four segments combined.
