Diagnosis.

This species has two forms: the blackish form and the whitish from. The blackish form can be differentiated by the forewing and the distal 2/3 of hindwing blackish brown. The whitish form is similar to Teliphasa albifusa superficially, but can be separated from the latter by the uncus subovate, the costa without process ventrally, and the phallus ventrally with two short digitiform distal processes that lack spines internally in the male genitalia (Fig. 19); the ductus bursae with one sclerotized subtriangular plate posteriorly, and the signum narrow rectangular in the female genitalia (Fig. 25). Whereas in Teliphasa albifusa , the uncus is trapezoidal, the costa has a subtriangular process ventrally, and the phallus ventrally with a short slender distal process that has a row of spines internally in the male genitalia; the ductus bursae with two irregular sclerotized plates posteriorly, and the signum is subtriangular in the female genitalia.
