Type Species

Diagnosis

Oediopalpa can be distinguished by 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
• the filiform antennae with 11-antennomeres
• 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
  having a seta in all four angles
• the anterior margin of the prosternumprosternum:
  contains two anterior coxal cavities
  projecting forward, partially covering the mouth
• the elytra at base being not much wider than the base 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 parallel-sided
• the elytra having no costae.

Description

Body more or less elongate, moderately convex.

Head: small; vertexvertex:
occupies the area behind and between the eyes
flat or weakly depressed; eyeeye:
elongate, slightly prominent, multifaceted; usually slightly kidney-shaped
oblong to oval, finely faceted; mouth small, exposed area covered by palps; mandible dentate.

Antenna: with 11-antennomeres; thick; antennomere 3 longest.

Pronotum: transverse, apex narrowed; regularly convex, may be impressed in each angle; sometimes with lateral impressions; disc with deep punctures; seta present in each angle.

Scutellum: quadrangular or pentagonal; rounded at apex.

Elytron: little 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
; slightly constricted behind 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
, then subparallel; apex conjointly rounded; lateral and apical margins finely serrate or smooth; with 10 rows of shallow punctures, scutellar row short; no costae.

Venter: prosternumprosternum:
contains two anterior coxal cavities
almost flat, expanded forward to partly cover mouth.

Leg: short, thick, femurfemur:
largest part of the leg; more or less cylindrical, attached at base to trochanter and at apex to tibia
widest, inner margin serrate or not.

Some species orange or reddish‑yellow brown; others may be metallic dark blue, green to black.
