Material examined. 1 ɗ, Beitun (47°19΄ N, 87°48΄ E), Xinjiang Uygur Autonomous Region, 530 m, 22. July 1994, leg. Houhun Li & Hongyan Qin; 2 ΨΨ, Jinghe (44°39΄ N, 82°50΄ E), Xinjiang, 24. Aug. 1994, leg. Duoliken Baishanbayi; 2 ɗɗ, Zepu (38°12΄ N, 77°18΄ E), Xinjiang, 2–10. Aug. 1994, leg. Aisihaer Maimaiti.

Diagnosis. This species looks somewhat similar to P. sarcogypsa , but can be separated from it by the forewing ochreous yellow mottled silvery white lines ( Fig. 1 a); in male genitalia, the valvae lack the basal lobes, and the manica is narrowed distally, with a truncate apex ( Fig. 1 b); in female genitalia, the signa consist of a pair of sclerotized carinae of irregular shape ( Fig. 1 c). In P. sarcogypsa (Meyrick) , the male valvae bear setose basal lobes and the female signa consist of paired rows of densely compact spines of similar shape and size.

Distribution. New to China (Xinjiang); also in Middle Asia, Southern and Central Europe, North Africa ( Riedl 1969; Koster & Sinev 2003).

Hostplants. Asteraceae : Carlina spp., Centaurea spp., Carduus spp., Cnicus benedictus L., Scolymus hispanicus L., Carthamus lanatus L. and C. tinctorius L., Pycnomon acarna (L.) ( Koster & Sinev 2003).
