Diagnosis.
This species is similar to P. obfuscalis in appearance and genitalia, but can be distinguished by the body color paler than the latter (Fig. 10); uncus short and broad triangular (Fig. 17 a); valva shorter and broader than the latter, with distal 1 / 3 narrowed very gradually and rounded apically (Fig. 17). In P. obfuscalis, the uncus is semicircular (Fig. 12 a); the distal 1 / 3 of the valva is narrowed gradually and pointed apically (Fig. 12).
