Synonomys

Acritispa Uhmann 1937: 336 (unavailable name).

Type Species

Physocoryna dilatata Uhmann.

Diagnosis

Acritispa can be distinguished by the following combination of characters:

• the lateral margins of the 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 the elytra without long, stiff spines
• the head without a frontal horn
• the 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
  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 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
  ; clavate; with 8-antennomeres, 7 and 8 almost fused
• elytra tuberculate

Description

Head: medial sulcus present; vertexvertex:
occupies the area behind and between the eyes
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.

Distribution

Bolivia, Brazil, Panamá, and Paraguay.
