  • lateral margin of pronotum and elytra without long, stiff spines
  • head without frontal horn between antennae
  • pronotum with seta in each anterior angle
  • apex of elytra without tooth-like projection
  • elytra without costae apically
  • antennae not thickened apically, apical 4 antennomeres similar to others
  • labrum small with clumps of setae as well as row of setae along anterior margin
  • mentum a regular octagon

Head: large; eye large, oval; with tubercle at base of antenna; labrum small with clumps of setae as well as row of setae along anterior margin; mentum octagonal; mandible large; maxillary palps with palpomeres 2 and 3 obconic, 4 elongate oval, as long as 2 and 3 combined.

Antenna: stout; cylindrical; filiform; ½ body length; with 11-antennomeres; antennomere 1 thick; 2 globose; 3 obconic, subequal in length to 1; 4 to 10 subequal in length; 11 longer than 10, obtusely rounded at apex.

Pronotum: quadrate; lateral margin slightly rounded medially; anterior margin slightly curved toward head, sinuate and emarginate medially.

Scutellum: sharply pointed at apex.

Elytron: elongate; lateral margin straight, smooth; exterior apical angle rounded; apex rounded; regularly punctate-striate; interspaces smooth apically.

Venter: prosternum narrow, slightly convex; mesosternum as wide as prosternum.
