Diagnosis. Head with median triangular projection, with long median carina reaching anterior margin of eyes, each eye composed of 4-5 ommatidia above long spine; antennae short, slightly exceeding posterior margin of pro- notum, with antennomeres 9 and 10 transverse, terminal antennomere symmetrical.

Redescription. Body ( Fig. 5 ) light reddish-brown, shiny, with long, dense setae on sides of head, pronotum and elytra, disc of elytra glossy with several setae, length 2.59 mm, maximum width of elytra 0.78 mm.

Head about as long as wide, rostrum in middle with triangular projection, clypeus rounded, head with median impression, vertex with long median carina reaching anterior margins of eyes, lateral carinae well-defined, supra-antennal tubercules prominet, eyes reduced to 4–5 ommatidia above long spines, median basal carina well-defined.

Antennae 0.98 mm long, scape short, 1.50 times as long as wide, 1.20 times as long as pedicel, antennomere III, V, X equal in lengths, slightly longer than IV, VI, VII and IX each, which are of equal lengths, antennomere VIII shortest, antennomeres IX and X hexagonal, both transverse, terminal antennomere 1.50 times as long as wide and 2.25 times as long as X.
