Synonomys

Oxyroplata Uhmann 1937f: 454 Nomen nudum.

Type Species

Uroplata bellicosa Baly.

Diagnosis

Oxyroplata 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, vertexvertex:
  occupies the area behind and between the eyes
  without medial 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 and 3 regular costae
• the antennae thickened at apex, compressed laterally, not clavate, with 8-antennomeres
• the prosternumprosternum:
  contains two anterior coxal cavities
  does not expand anteriorly to partly cover the mouth

Description

Pronotum: longer than wide; widest at base; tooth present in anterior angle; basal impression present.

Scutellum: quadrate.

Elytron: lateral margin dentate, margined; apical margin laminate, strongly dentate, subcordate‑emarginate; with 10 rows of punctures; 4 costae, 2 and 4 strongly elevated, 1 complete, 3 visible at base and apex.
