. Body oblong, including legs reddish brown, frons darker, antenna yellow, elytra with more or less large dark spots, punctures on elytra lighter, dorsal surface dull; elytra with sparse, short, adpressed white setae, otherwise glabrous.
Labroclypeus as wide as long, widest at base, lateral margin almost straight and moderately convergent anteriorly, anterior angles acute, anterior margin widely and deeply emarginate medially, margins strongly reflexed; surface flat, shiny, finely and densely punctate, with dense transverse wrinkles and a few long, erect setae behind anterior margin; frontoclypeal suture distinct, finely incised and weakly curved; smooth area anterior to eye large and convex, about 1.5 times as wide as long; ocular canthus moderately long and narrow triangular (1/4 of ocular diameter), smooth, with short terminal seta. Frons flat, entirely dull; surface with fine and irregularly dense punctures, with a few short setae on disc and beside eyes. Eyes large, ratio diameter/interocular width: 0.86. Antenna with nine antennomeres; antennomeres six and seven transverse and short; club with three antennomeres, three times as long as remaining antennomeres combined and strongly reflexed.
