Etymology.

The species epithet refers to the type locality; noun.

Diagnosis.

This species resembles P. wenyang Zhao & Li, sp. n. (Figs 21-23) but can be distinguished by following characters: bulb curved dorso-medially (Figure 13D) (bulb curved dorso-subdistally in P. wenyang Zhao & Li, sp. n.), larger Esl/El ratio (0.63-0.67, n = 6, mean = 0.65, Suppl. material 1: Figure S6) (smaller Esl/El ratio 0.51-0.55, n = 5, mean = 0.53 in P. wenyang Zhao & Li, sp. n.), and smaller El/Bl ratio (1.24-1.31, n = 6, mean: 1.27, Suppl. material 1: Figure S6) (larger El/Bl ratio 1.47-1.54, n = 5, mean: 1.49 in P. wenyang Zhao & Li, sp. n.).
