  • the head without a frontal horn; mouthparts not projecting forward, interantennal carina not distinct
  • the pronotum with a seta in each anterior angle
  • the apex of the elytra without a tooth-like projection
  • the elytra without costae, rounded, posterior margin smooth
  • the antennae with 11-antennomeres, filiform, antennomeres 1 and 2 subglobular
