Diagnosis.
This species resembles P. tangi Wang, Mi & Peng, 2016 (Wang et al. 2016: 130, figs 1 A – G, 2 A – D) in having similar shaped spermathecae, but differs it from the latter by the knife-like ventral tibial apophysis (vs rhabditiform and slightly curved in P. tangi), the multiple spines at the base of ventral tibial apophysis (vs spine absent in P. tangi), the folded posterior half part of conductor (vs knife-shaped in P. tangi), and the kidney-shaped spermathecae (vs long oval in P. tangi) (Fig. 6). This new species also resembles P. gongshan (Yang, Zhu & Song, 2006) (Benjamin 2011: 80, figs 47 A, B, D – F, 49 A – F, 51 A – D) in having a similar shaped bulb, but it can be distinguished by the bifurcated tip of the conductor (vs not bifurcated in P. gongshan) and the small copulatory openings located towards the posterior (vs large copulatory openings towards the lateral).
