Type Species

Cladophora fasciatus Guérin-Méneville.

Diagnosis

Octocladiscus can be distinguished by the following combination of characters:

• the lateral margins of the 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 the elytra without long, stiff spines
• the head without a frontal horn; mouthparts not projecting forward
• the 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
  with a seta in each anterior angle
• the apex of the elytra without a tooth-like projection
• the elytra without costae, rounded
• the antennae with 11-antennomeres, pectinate (comb-like) from antennomeres 4 to 10

Description

Body broadly oval, flattened.

Head: vertexvertex:
occupies the area behind and between the eyes
punctate; eyeeye:
elongate, slightly prominent, multifaceted; usually slightly kidney-shaped
finely faceted.

Antenna: with 11-antennomeres, 1/2 length of body; antennomeres 2 and 3 short, following antennomeres longer; male pectinate from antennomeres 4 to 10; female filiform, with projection on antennomeres 4 to 10.

Pronotum: at midline 2x as wide as long; lateral margin strongly rounded, narrowing anteriorly; disc impunctate; large shallow punctures present laterally and basally.

Scutellum: elongate triangle.

Elytron: oblong-oval, wider than 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
; margined laterally; pygidium visible from above; with 10 rows of punctures plus scutellar row.

Venter: with 5 visible abdominal sterna.

Distribution
