P. cuneata matsumurai : CHINA: Taiwan ( BMNH): 1Ƥ, Central Formosa, Arizan, vis-à-vis Mt Mòrrisson Kagé district, 8000 ft, VI-VII.1908, ex. Moltrecht, Ex Oberthür Coll. Brit. Mus. 1927-3, BMNH (E) #1008387; 1Ƥ, BMNH genitalia slides examined (Inoue slide no. 9507).

Diagnosis. P. cuneata can be recognized easily by the distinct, diffuse and broad median and terminal bands on the hindwing, often very large wedge-shaped mark, and the large antemedial patch on the inner margin of the forewing. The male genitalia are distinctive in that the lower half of the valva apex is truncate (the ventral margin of the valva is bent inward in the terminal half); the aedeagus has three bundles of vesica spines as in P. gracilis and P. spurcataria , but all the spines are shorter than in those species. The female genitalia share a very long and narrow antrum, ductus bursae, and rounded corpus bursae with P. boarmiata , but the joint between antrum and ductus bursae is suddenly expanded in P. cuneata .

Distribution. China ( Taiwan, Yunnan, Tibet), India, Japan.

Remarks. Two subspecies of P. cuneata occur in China: P. cuneata cuneata Walker, 1860 distributed in Yunnan and Tibet, and P. cuneata matsumurai Bastelberger, 1909 (Ent. Z., Frankf. a. M. 23 (8): 39) distributed in Taiwan, which lacks the hindwing median band.
