Diagnosis

 

Serratispa can be distinguished by the following combination of characters:

  • the lateral margins of the pronotum and the elytra lacking long, stiff spines
  • the head lacking a frontal horn
  • the pronotum with a seta in each anterior angle
  • the apex of the elytra lacking a tooth-like projection
  • the antennae being not thickened at the apex
  • the antennae having 11-antennomeres with the apical four being different from the others (either longer or shorter, thinner or thicker, more pubescent, different in color)
  • the body being more or less convex
  • the legs being short
  • the sides of the of the elytra not being nearly vertical from costa 3
  • the elytra with four prominent costae with the lateral margins rounded
