Chalepotatus Weise 1910b: 133

Synonomys

Macrochalepus Pic 1929d: 4.

Type Species

Odontota coarctatus Chapuis (=Chalepotatus scitulus Weise).

Diagnosis

Chalepotatus 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
• 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, finely margined, without lateral teeth
• the apex of the elytra without a tooth-like projection
• the elytra with 10 rows of punctures at base and 9 on apex and 4 regular costae, humerus rounded without spine or tooth
• the antennae thickened at apex, with 11-antennomeres
• leg with apical tarsomere bearing 2 claws
• anterior margin of prosternumprosternum:
  contains two anterior coxal cavities
  expanding toward mouth

Description

Body elongate, moderately flattened.

Head: clypeusclypeus:
usually quadrangular, elongate; joined to the labrum
smooth or setose, with medial carina ending in a tooth before antennal base.

Antenna: with 11‑antennomeres.

Pronotum: lateral margin rounded; disc smooth, shiny.

Elytron: at humeri 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
, sides moderately parallel; apex conjointly rounded; with 10 rows of punctures plus scutellar row, puncture rows 5 to 8 narrowed to two rows on basal ½; 4 costae, costa 3 united with 4 for ¼ its length.

Venter: prosternumprosternum:
contains two anterior coxal cavities
with mid‑anterior projection.

Leg: short.
