  occupies all of dorsal part of the prothorax; in anterior angles or posterior angles there may be a small tubercle or pore with a seta
  with a seta in each anterior angle
• the apex of the elytra without a tooth-like projection
• the elytra with 8 continuous rows of punctures with sutural margin not carinate; with 3 regular costae, humerus rounded, lateral and apical margins serrate
• the antennae thickened at apex, with 8-antennomeres, antennomere 1 not laterally compressed, 2 subglobose
