Diagnostic characters.
The species can be separated from other members of the genus by having an antenna with 10 flagellomeres; AR 0.31; superior volsella (not clear in the available material) probably fused with the gonocoxite; inferior volsella broad and with a small prominent part; sternapodeme inverted Ushaped; and gonostylus medially expanded.

Sternapodeme inverted U-shaped, coxapodeme 38 µm long, small attachment point with phallapodeme placed in caudal position of sternapodeme and caudally directed; phallapodeme short, weakly curved, not extending beyond margin of tergite IX, 35 µm long. Gonocoxite 68 µm long, with 2 long setae apically. Gonostylus 35 µm long; megaseta 5 µm long. HR 1.9, HV 3.5. The wing and the hypopygium of the
