None.

Type Species

Ceratispa (Ceratispa) loriae Gestro.

Diagnosis

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

• lateral margin of 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 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 pronotum:
  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 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 prosternumprosternum:
  contains two anterior coxal cavities
  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; eyeeye:
elongate, slightly prominent, multifaceted; usually slightly kidney-shaped
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 prosternumprosternum:
contains two anterior coxal cavities
not projecting forward, not partly covering mouth; punctate laterally.

Leg: short; robust.
