Synonomys

None.

Type Species

Agonia manilensis Weise.

Diagnosis

Agoniella 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
• 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, narrower than base of elytra, strongly convex, with 2 deep impressions basally
• elytra without scutellar row of punctures, parallel-sided, humerus angulate, glabrous, bicostate
• tarsi with 2 claws
