  • pronotum with seta in each angle, flattened, never constricted basally, lateral margin narrowly margined
  • anterior margin of prosternum not projecting forward, not partly covering mouth
  • less than 14 mm in length
  • antennae with 11-antennomeres, antennomere 3 shorter than 1 and 2 combined
  • pronotum slightly prolonged over head, with 10 deep pits, pubescent on anterior ½
  • elytra with interspace 4 costate



Elongate; weakly convex; reddish-brown; length 3.5 to 7.0 mm.

Head: large; with blunt projection between antennal bases; labrum transverse; mandible with apex truncate; maxillary palps with palpomere 1 small, 2 and 3 very small, obconic, 4 longer than 2 and 3 combined, oval; labial palps with palpomere 1 small, 2 obconic, 3 ovate; eye large, convex.

Antenna: reaches to humerus; robust; thickening apically; with 11-antennomeres; antennomeres 1 and 2 rounded; 3 elongate, subconic; 4 to 10 subequal in length; 11 slightly longer than 10, pointed at apex.
