Diagnosis

 

Ceratispa (Ceratispa) can be distinguished by the following combination of characters:

  • lateral margin of pronotum and elytra without long, stiff spines
  • head with narrow frontal horn between antennae, horn as long as antennomere 1 in male, shorter than 1 in female
  • antennae filiform, antennomere 1 without spine-like process
  • pronotum with anterior angles oblique, with seta in each anterior angle
  • elytra with 8 rows of punctures basally plus scutellar row, 10 apically, interspaces 2 and 4 wider than others, apical margin truncate
  • anterior margin of prosternum not projecting forward, not partly covering mouth

Description

 

Elongate; subdepressed; subparallel; color yellow, brown or black, often with metallic sheen; total length 9.0 to 13.0 mm.

Head: cephalic plate quadrate, with medial sulcus; frontal horn narrow, as long as antennomere 1 in male, shorter than 1 in female; eye large, convex.

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

Pronotum: transverse; lateral margin rounded, then constricting and converging, sometimes with small tooth; anterior angles oblique, with seta; anterior margin rounded; posterior angle acute; posterior margin bisinuate; surface densely punctate.

Scutellum: cordate.

Elytron: lateral margin straight, smooth; exterior apical angle rounded; apical margin truncate; humerus angulate, not produced; with 8 rows of punctures basally plus scutellar row, 10 apically, interspaces 2 and 4 wider than others; interspaces 2 and 4 costate, costae wide.

Venter: anterior margin of prosternum not projecting forward, not partly covering mouth; punctate laterally.

Leg: short; robust.
