  • the head without a frontal horn; mouthparts projecting forward
  • the pronotum with a seta in each anterior angle
  • the apex of the elytra without a tooth-like projection
  • the elytra without costae, rounded, margins serrulate
  • the antennae with 11-antennomeres, filiform, antennomere 3 not the longest
