Head. Head with pre-orbital carina absent or hardly distinct; post-orbital carina present and reaching geno-temporal margin; antennal clava slightly shorter or at the most as equal to twice length of preceding segment;

Mesosoma. Pits on mesosoma close and interstices carinate and rugose; apex of scutellum rounded or slightly entire. Dorsal margin of pronotal panel slightly arched.

Wings. Fore wing with PMV 0.33-0.36 × length of MV; SMV slightly shorter than twice MV.

Legs. Hind coxa without ventro-mesal tooth; hind femur without an inner basal tooth, outer ventral margin with a row of irregular teeth.
