  • the head without a frontal horn
  • the pronotum with a seta in each anterior angle
  • the apex of the elytra without a tooth-like projection
  • the elytra with 8 rows of punctures plus short scutellar row, with 3 regular costae
  • the antennae thickened at apex, not clavate, with 7-antennomeres, last antennomere rounded at apex
  • the prosternum expanding anteriorly to partly cover the mouth
