Type Species

Unguispa impar Uhmann.

Diagnosis

Unguispa can be distinguished by the following combination of characters:

• lateral margin of pronotumpronotum:
  occupies all of dorsal part of the prothorax; in anterior angles or posterior angles there may be a small tubercle or pore with a seta
  and elytra with long, stiff spines
• antennomere 1 without spine
• pronotum pronotum:
  occupies all of dorsal part of the prothorax; in anterior angles or posterior angles there may be a small tubercle or pore with a seta
  with anterior margin with bifurcate spine on each side
• tarsal claws not fused, asymmetrical; tibiatibia:
  variable in length; joins femur and tarsus
  greatly expanding apically
