Diagnosis

 

Nesohispa can be distinguished by the following combination of characters:

  • lateral margin of pronotum and elytra without long, stiff spines
  • head with wide, spoon-like frontal horn between antennae, eyes not prominent
  • antennae short, scarcely reaching to anterior margin of pronotum, antennomere 1 without spine-like process
  • pronotum with anterior angles obliquely truncate, tooth-like, with seta in each anterior angle
  • elytra with 8 rows of punctures basally, 10 rows apically plus scutellar row
  • prosternum with anterior margin not expanding forward
