Diagnosis

 

Metazycera can be distinguished by the following combination of characters:

  • body wedge-shaped
  • the lateral margins of the pronotum and the elytra without long, stiff spines
  • the head without a frontal horn
  • 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, humerus angulate without spine or tooth
  • the antennae thickened at apex, filiform, with 11-antennomeres
  • leg with apical tarsomere bearing 2 claws
  • anterior margin of prosternum not expanding toward mouth
  • abdominal sterna 1 and 2 with deep sulcus in middle
