Etymology.

The species epithet refers to the type locality; noun.

Diagnosis.

This species resembles P. lizhuang Zhao & Li, sp. n. (Figs 12-15) but can be distinguished by following characters: bulb curved dorso-distally (arrow in Figure 21B) (bulb curved dorso-medially in P. lizhuang Zhao & Li, sp. n.), smaller Esl/El ratio (0.51-0.55, n = 5, mean: 0.53, Suppl. material 1: Figure S9) (larger Esl/El ratio 0.63-0.67, n = 6, mean: 0.65 in P. lizhuang Zhao & Li, sp. n.), and larger El/Bl ratio (1.45-1.54, n = 5, mean: 1.49, Suppl. material 1: Figure S9) (smaller El/Bl ratio 1.23-1.29, n = 6, mean: 1.27 in P. lizhuang Zhao & Li, sp. n.).
