  • the lateral margin of the pronotum and the elytra lacking long, stiff spines
  • the head lacking a frontal horn
  • the pronotum having a tuft of setae in each angle
  • the antennae having 11-antennomeres, filiform
  • the elytral punctures not being in regular rows
  • the elytra lacking costae
  • the pronotum being nearly as wide as the base of the pronotum
  • the body being nearly oval.
