  • pronotum with seta in each angle, flattened, never constricted basally, lateral margin narrowly margined
  • anterior margin of prosternum not projecting forward, not partly covering mouth
  • less than 14 mm in length
  • elytra without transverse carinae forming an irregular net-like sculpture
  • antennae with 6-antennomeres, antennomere 6 with sensory pits on lower surface
