Diagnosis

Euprionota 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
  with 3 to 5 sulci
• 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, lateral and apical margins of elytra denticulate, exterior apical angle with strong tooth
• the antennae thickened at apex, not clavate, with 8-antennomeres
• the prosternumprosternum:
  contains two anterior coxal cavities
  does not expand anteriorly to partly cover the mouth
