None.

Type Species

Calamispa fasciata Gressitt.

Diagnosis

Calamispa 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 without long, stiff spines
  • head with frontal horn between antennae
  • antennomere 1 without spine-like process
  • anterior angle 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
    not projecting
  • elytra without scutellar row, no costae
  • anterior margin of prosternumprosternum:
    contains two anterior coxal cavities
    not projecting forward, not partly covering mouth
