Micrispa Gestro 1897b: 65

Synonomys

None.

Type Species

Gonophora sinata Gestro.

Diagnosis

Micrispa 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
• body broad, expanding apically
• head without frontal horn between antennae, clypeusclypeus:
  usually quadrangular, elongate; joined to the labrum
  well-developed
• 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, cordate, lateral margin broadly margined
• elytra without scutellar row of punctures, with 8 rows of punctures, tricostate
• tarsi with 2 claws
