Diagnosis

 

Exothispa can be distinguished by the following combination of characters:

  • Large (>17 mm)
  • Lateral margin of pronotum or elytra without long, stiff spines
  • Head without frontal horn between antennae
  • Pronotum with lateral margin straight, with seta in each anterior and posterior angle
  • Elytra at base nearly 2x as wide as pronotum
  • Anterior margin of prosternum not projecting forward, not covering mouth

Body glabrous; shining; narrowed anteriorly, widened posteriorly; reddish-brown, mouth, eyes, antennae, and legs black.

Head: elongate; vertex with 3 sulci; frons simple; eye small, weakly rounded, placed distant from anterior margin of pronotum; maxillary palps with apical palpomere ovate, preceding ones thicker.

Antenna: as long as head and pronotum combined; thick, with 11-antennomeres; antennomere 1 subglobose, large; 2 to 10 transverse; 8 very short; 11 pointed at apex.

Pronotum: longer than wide; lateral margin straight; anterior angle acute; posterior angle with small tooth; posterior margin bisinuate; glabrous; surface punctate, punctures sparser laterally.

Elytron: at base nearly 2x width of pronotum; exterior apical angle rounded; surface lightly punctate-striate; humerus tuberculate, carinate.

Venter: prosternum narrow between coxae, sinuate posteriorly; mesosternum with transverse tubercle apically; abdominal sterna conical, impunctate laterally, suture between sterna obsolete medially.
