Synonomys

None.

Type Species

Amblispa dohrni Baly.

Diagnosis

Amblispa can be distinguished by the following combination of characters:

• body convex, parallel-sided
• 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
• 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 seta in each posterior angle, anterior angle distinctly rounded
• elytra with scutellar row of punctures
• antennomere 3 not 3x length of 2
• tarsomere 2 not concealed by setae of tarsomere 3
• head with triangular projection between antennae, eyes small, flat
• 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
  without lateral depressions
• suture between abdominal sterna 1 and 2 complete
