Diagnosis

 

Temnochalepus can be distinguished by the following combination of characters:

  • body elongate, parallel-sided
  • the lateral margins of the pronotum and the elytra without long, stiff spines
  • the head without a frontal horn, sharp constriction present behind eyes
  • the pronotum 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 for entire length and 4 regular costae, costa 3 interrupted in middle or is totally absent, humerus rounded without spine or tooth, apices regularly rounded, sutural angle not emarginate
  • the antennae thickened at apex, with 11-antennomeres
  • leg with apical tarsomere bearing 2 claws
  • anterior margin of prosternum not expanding toward mouth
  • abdominal sterna 1 and 2 without medial sulcus

Description

 

Body elongate, parallel-sided.

Head: clypeus hardly granulose, with medial carina which is prolonged into a deep interocular sulcus; sharp constriction present behind eyes; projection present at base of antenna.
