Plesispa Chapuis 1875: 290





Type Species


Plesispa reichei Chapuis.



Plesispa can be distinguished by the following combination of characters:

  • lateral margin of pronotum and elytra without long, stiff spines
  • head with narrow frontal horn ½ length of antennomere 1, with small lamina visible from above below antennal bases
  • antennomere 1 without spine-like process
  • pronotum with anterior angles oblique, each anterior angle with seta
  • elytra with 8 rows of punctures plus scutellar row basally, 10 rows apically
  • prosternum with anterior margin not expanding forward



Body elongate; subparallel; subdepressed; color brown with some black; total length 5.0 to 9.0 mm.

Head: small; cephalic plate quadrate; frontal horn elongate, narrow, rounded at apex, ½ length of antennomere 1; with small lamina visible from above below antennal bases; labrum short, emarginate; eye large, convex.

Antenna: filiform; reaches to humerus; with 11-antennomeres; antennomere 1 subincrassate; 2 and 3 subequal in length, cylindrical; 4 to 10 subequal in length, each shorter than 3; 11 longer than 10, pointed at apex.

Pronotum: transverse; lateral margin straight at base, then sharply angulate and converging to anterior angle; anterior angle oblique, with tooth and seta; anterior margin weakly curved; posterior angle acute; posterior margin bisinuate; surface punctate.

Scutellum: small; cordate.

Elytron: lateral margin straight, smooth; exterior apical angle rounded; apical margin rounded; humerus angulate, not produced; with 8 rows of deep punctures plus scutellar row basally, 10 rows apically; tricostate.

Venter: prosternum with anterior margin not expanding forward.

Leg: short; femur thickened; tibia emarginate apically.
