Body medium to large, oval, strongly convex dorsally, densely covered with short pubescence. Pronotum reddish brown, lateral margins yellowish brown at both ends, slightly concave, surface rough with dense punctures and pubescence, longer than those on head. Frons trapezoidal, with fine punctures and dense short hairs. Elytra each bearing five distinct reddish-brown spots, of which the third forms a trapezoidal marking that collectively creates a large pentagonal spot across the suture. Abdominal postcoxal lines incomplete, extending to 1/6 length of abdominal ventrite 1. Male genitalia: penis slender, bent at 1/3 length with slight curvature, evenly shaped, apex slightly swollen then narrowed to sharp tip; penis guide robust, thickest at middle, curved inwardly at 3/4, gradually narrowing to pointed apex, basal margin serrated, bearing moderately dense long setae. Parameres longer than penis guide, widest at base, gradually narrowing to bluntly rounded apex, with sparse short setae from basal 1/3 toward apex.
