The elytra lack ribs and they are wrinkled, the spots are umbilical, short-bristled, and surrounded by a grey tomentose circle, which is wider at the rear than at the front. The pygidium is not particularly densely covered with bristled umbilical spots. Its anterior margin and lateral edges are dull. The center of the underside and the legs are glossy, while the sides of the thorax and abdomen are dull and pruinose. The punctation of the underside is moderately dense.
