Diagnosis. P. angulifera is distinguished by the clear golden brown borders to the black patches on the forewing, though its wing pattern is similar to P. szetschwana . These two species can be distinguished by the following characters: the ground colour of P. angulifera is much darker than that of P. szetschwana ; the medial line on the hindwing in P. angulifera is not as distinct as in P. szetschwana . In the male genitalia, P. angulifera shares the characters of very narrow costal basal lobe and valva with P. szetschwana ; the valva is almost straight in P.

angulifera but the tip is curved in P. szetschwana ; the tip of the costal basal lobe is tapering in P. angulifera but swollen in the latter; in addition, the saccus is not expanded in P. angulifera but projects as a triangle in P. szetschwana ; the aedeagus has two bundles of spines as in P. cuneata , P. szetschwana , P. gracilis , P. spurcataria and P. crypta , but bears more spines; the cornutus is less pointed and slender than in most other species, but as broad as in P. bluethgeni and P. breviprotrusa . In the female genitalia, the antrum and ductus bursae are broader than in most other species; the corpus bursae is much bigger and longer than the ductus bursae and antrum, while in other species, except for P. bluethgeni , the corpus bursae is quite small.

Distribution. China (Hubei, Sichuan, Yunnan, Tibet), India, Nepal.
