Diagnosis
The imagines are separable from other members of the genus by the combination of having wings nearly fully dark with two broad bands partly fused, bare squama, uniserial dorsocentrals, one prealar, no pseudospurs, and tibiae ringed with white (at least in female). The male has a low adpressed inferior volsella and a slender bare appendix of the gonostylus. The seminal capsule of the female is shorter than the cercus and much shorter than the notum, with the neck about one-fourth as long as the capsule.
The presence of posterior spines on sternites II-VII or VIII combined with the lack of tubercules on tergites or conjunctives separate the pupa from other members of the group.
The larva has weak claws on posterior parapods; mentum at least slightly darker than head capsule, with single, more or less triangular median tooth, with distinct ventral tooth posterior to the first lateral tooth, and indication of a ventral tooth lateral to median tooth; antennal ratio 0.52-0.54; and postmentum 110-113 μm long.
