Synonomys

None.

Type Species

Nesohispa lambaciras Maulik.

Diagnosis

Nesohispa can be distinguished by the following combination of characters:

• lateral margin of 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 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 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
  , antennomere 1 without spine-like process
• pronotum pronotum:
  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 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 prosternum:
  contains two anterior coxal cavities
  with anterior margin not expanding forward
