Diagnosis

 

Oediopalpa can be distinguished by following combination of characters:

  • the lateral margins of the pronotum and the elytra without long, stiff spines
  • the head without a frontal horn
  • the filiform antennae with 11-antennomeres
  • the pronotum having a seta in all four angles
  • the anterior margin of the prosternum projecting forward, partially covering the mouth
  • the elytra at base being not much wider than the base of the pronotum and parallel-sided
  • the elytra having no costae.
