Diagnosis

 

Mimoecthispa can be distinguished by the following combination of characters:

  • the lateral margins of the pronotum and the elytra without long, stiff spines
  • the head without a frontal horn, frons projecting, vertex without medial sulcus
  • the pronotum with a seta in each anterior angle
  • the apex of the elytra without a tooth-like projection
  • the elytra with 8 rows of punctures at base and 9 apically, with 3 weak costae
  • the antennae thickened at apex, not clavate, with 8-antennomeres, antennomere 8 the largest
  • the prosternum does not expand anteriorly to partly cover the mouth
