Antennal scapus small, rounded, with a fine tuft of few setae as long as the antennal club; club with two transverse or weakly procurved sutures. Pronotum broader than long, anterior half strongly asperate, posterior half smooth or finely rugose; vestiture consisting mainly of evenly distributed, coarse, spatulate setae, fewer and very fine setae intermixed.
