  • the head without a frontal horn; mouthparts not projecting forward, interantennal carina not distinct
  • the pronotum with a seta in each anterior angle
  • the apex of the elytra without a tooth-like projection
  • the elytra without costae, rounded, posterior margin smooth
  • the antennae with 11-antennomeres, filiform, antennomeres 1 and 2 subglobular



Body elongate, almost parallel-sided or slightly narrowed posteriorly.

Head: interantennal area narrow (not wider than first antennal antennomere), flat or slightly convex, not carinate.

Antenna: with 11-antennomeres; antennomeres 1 to 2 short, subglobular; 3 distinctly longer than 2; 1 to 2 sparsely pubescent and shiny, 3 to11 densely pubescent, dull.

Pronotum: widest at base, slightly narrower than base of elytra; sides on basal 1/3 parallel or slightly converging anteriorly; explanate sides very narrow, not wider than width of antennomeres.

Elytron: with 10 rows of lightly impressed punctures plus short scutellar row; explanate margin narrow, at widest not wider than two elytral intervals combined.
