Colour and lustre: mandibles reddish brown; head brownish black; pronotum reddish brown, less dark on disc; elytra dark brown, each with 2 spots; anterior spot broad, transverse, starting in basal fifth, covering intervals 2 to 7 and a small portion of 8; posterior preapical spot situated far from apex, transverse and rounded, covering intervals 2 to more than half of 8; palps, antennae and tarsi reddish yellow, tibiae and femora brownish, darkened; dorsum rather shiny, setation not discernible; venter dark reddish brown, shiny. Head: with eyes strongly protruding; temples reduced; frontal grooves short and oblique, linear; mentum deeply emarginate, without tooth; labrum narrow and transverse, tip of ligula with four bristles; paraglossae narrow, smooth. Pronotum: 1.66x times as wide as long; sides clearly and arcuately narrowing anteriorly, weakly narrowing toward base; greatest width just before middle; anterior angles not deflected, clearly protruding, moderately widely rounded; anterior margin strongly sinuate; posterior angles weakly obtuse, not very acute apically; posterior setigerous puncture directly adjacent to basal ridge of posterior angles; base shortly sinuate at level of basal impressions; medially weakly arcuate; disc feebly convex, prebasally transversely broadly depressed; marginal groove narrow anteriorly, evenly and strongly widened posteriorly, ending in broad, not sharply delineated pits of basal impressions; median line weakly incised anteriorly, more strongly incised toward base. Elytra: elongate, rather strongly oval, distinctly convex; sides weakly sinuate preapically, ends of this arch sharply angled; elytral apex shortly declivous; striae moderately deep, smooth at bottom; intervals flat; marginal groove wider medially, narrower apically and basally.
