Type material. Holotype. ³, CHINA: Mt. Zhaogong, 1400–1600 m, 103°51’E, 30°97’N, Dujiangyan , Sichuan Province, 12.x.2013, (Jun-yu Zhang) ( SYNU).

Paratype, CHINA: 1³, same data as holotype .

Remarks. The new species is similar to P. ampycocerca Xue & Yang, 1998 , but differs in the following features: eye bare (in P. ampycocerca ciliate), postgena setulae brownish yellow (in P. ampycocerca black), palpus black (in P. ampycocerca brown); only apical part and lateral margin of scutellum brownish yellow (in P. ampycocerca dark brown), posterior spiracle brown (in P. ampycocerca yellow); hind femur without pv (in P. ampycocerca with a row); two sides of the cerci not round in posterior view (in P. ampycocerca round).

Etymology. The species name, in apposition, is based on the name of collector Junyu Zhang.

Geographic distribution. China: Sichuan Province (Dujiangyan).
