Synonomys

Octuroplata Uhmann 1937f: 454 Nomen nudum.

Type Species

Uroplata octopustulata Baly.

Diagnosis

Octuroplata 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, fronsfrons:
  upper anterior portion of head capsule above the clypeus
  not projecting, vertexvertex:
  occupies the area behind and between the eyes
  without sulcus
• 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 short scutellar row, with 3 regular costae
• the antennae thickened at apex, not clavate, with 8-antennomeres, last antennomere pointed at apex
• the prosternumprosternum:
  contains two anterior coxal cavities
  does not expand anteriorly to partly cover the mouth
