Diagnosis

 

Acritispa can be distinguished by the following combination of characters:

  • the lateral margins of the pronotum and the elytra without long, stiff spines
  • the head without a frontal horn
  • the pronotum with a seta in each anterior angle
  • the apex of the elytra without a tooth-like projection
  • antennae short, barely reaching the anterior margin of the pronotum; clavate; with 8-antennomeres, 7 and 8 almost fused
  • elytra tuberculate

Description

 

Head: medial sulcus present; vertex micropunctate.

Antenna: with 8‑antennomeres; antennomeres 1 and 2 subequal in length; 3 widened apically; 7 as wide as 8, difficult to distinguish; 8 hirsute club.

Pronotum: wider than long; tooth present in anterior angle; lateral margin evenly convergent from base to apex; two tooth‑like projections present on lateral margin; densely coarsely punctate.

Elytron: tuberculate; greatly expanded at apex; lateral and apical margins dentate; with lateral and transverse plicae (folds); translucent at exterior apical angle.

Leg: profemur expanded apically.
