Diagnosis

 

Promecotheca can be distinguished by the following combination of characters:

  • lateral margin of pronotum and elytra without long, stiff spines
  • head without frontal horn between antennae
  • pronotum with seta in all four angles, constricted apically and basally, lateral margin obsolete
  • anterior margin of prosternum not projecting forward, not partly covering mouth
  • antennae ½ body length, filiform
  • elytra without tooth in sutural angle
  • hind leg long, slender

Description

 

Elongate; subparallel.

Head: large; not prolonged between antennae; labrum transverse, subemarginate; mandible robust, truncate; maxillary palps thick, pubescent, palpomere 1 very short, 2 and 3 obconic, subequal in length, 4 longer than 3; eye large, convex, oblong-ovate.

Antenna: filiform; at least ½ body length; antennomere 1 subglobose; 2 obconic, shorter and more slender; 3 longer than 1 and 2 combined; 4 to 7 obconic, decreasing in length; 8 to 10 cylindrical, each shorter than 7; 11 longer than 10, rounded at apex.

Pronotum: cylindrical; convex; lateral margin obsolete; anterior margin slightly produced over head; with apical and basal constrictions plus strong tubercle between constrictions.

Scutellum: oblong, rounded at apex.

Elytron: lateral margin straight, smooth; exterior apical angle rounded; apex rounded, smooth; without tooth in sutural angle; with 8 regular rows of punctures, scutellar row absent; even interspaces subcostate.

Venter: prosternum sinuate at base; mesosternum twice as wide.

Leg: hind leg long, slender; femur without tooth.
