Diagnosis.
This species resembles

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
