Frons weakly convex, with a distinct, sharply elevated, longitudinal carina extending from epistomal margin to upper level of eyes; surface dull, densely, and finely punctate-granulate, with fine, golden-brown setae. Antennal funicle 5-segmented; club conical slightly flattened, with three transverse sutures. Pronotum 1.2–1.44 × wider than long, widest slightly behind middle; lateral margin evenly arcuate, more strongly converging on anterior half; surface densely, finely granulate and weakly punctate, with scattered, long, golden-brown setae. Elytra 1.18–1.38 × longer than wide; sides weakly arcuate, apex narrowly rounded; discal striae very narrow, shining, lightly impressed, more strongly impressed toward declivity, strial punctures fine, shallow; discal interstriae much wider (2–4 ×) than striae, granulate, with 3 or 4 rows of long, fine, appressed, golden-brown setae.
