Synonomys

Oethispa (misspelling).

Type Species

Uroplata (Octhispa) fossulata Chapuis.

Diagnosis

Octhispa can be distinguished by the following combination of characters:

• the lateral margins of the 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 the elytra without long, stiff spines
• the head without a frontal horn, sulcus present on outer margin of each eye
• the 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
  with a seta in each anterior angle
• the apex of the elytra without a tooth-like projection
• the elytra with 8 rows of punctures for entire length plus a short scutellar row; with 3 regular costae, humerus may have tooth, lateral and apical margins dentate
• the antennae thickened at apex, slightly clavate, with 8-antennomeres
• the prosternumprosternum:
  contains two anterior coxal cavities
  does not expand anteriorly to partly cover the mouth
