Above superior appendages an internal curved spine together with an external rounded process on each side; superior appendages long, bent near middle. Inferior appendages short, stout, tapering to apex ventrally in lateral view, with apical inner teeth; dorsal arm wide, expanded apically; apical expansion bent inward with outer angle bearing a central tubercle; points of expansion sub-equal in length, bearing internal teeth. Aedeagus with mid-length lateral expansions and a dark apical dorsal flap. ”

Wise measured the length of the forewings as 11.5 mm (0.45 in).
