Hispines of the World


Microrhopala Chevrolat 1836: 389





Type Species


Hispa vittata Fabricius.



Microrhopala 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
  • the elytra with 8 rows of punctures for entire length plus short scutellar row, with 3 weak costae
  • the antennae thickened at apex, not clavate, with 8-antennomeres
  • the prosternum does not expand anteriorly to partly cover the mouth



Head: subglobular; vertex impressed, impression bordered on each side by longitudinal row of punctures; medial sulcus present; frons not projecting; area surrounding eye punctate.

Antenna: reaching beyond base of pronotum; with 8-antennomeres; antennomeres 7 and 8 wider and more pubescent than preceding.

Pronotum: longer than wide, widest posteriorly, often narrowed anteriorly, narrower than elytra at humeri; convex; anterior margin straight, lateral margin straight, arcuate, sinuate or bisinuate, posterior margin bisinuate; punctation usually dense; a slender, usually slightly elevated strip lacking coarse punctures present in front of scutellum.

Elytron: longer than wide; usually slightly narrowed behind humerus; with 8 rows of punctures plus a scutellar row; rows 1 and 2 extending to apex, 8 and 9 separate or sometimes confused apically, extending to near suture where they unite with 1 and 2; intervals 1 and 9 and also 3 and 7 uniting apically; interval 9 strongly elevated.

Venter: prosternum margined anteriorly by row of short setae; abdomen sparsely punctate and pubescent, apical sternite more coarsely punctate and often more pubescent than preceding sterna.
