Miao leg.; P2020001, P2020010, P2020011, P2020034, P2020039, P2020053, P2020054, P2020055.

Diagnosis.

Males of P. xishan sp. nov. can be distinguished from those of P. albimana by the longer embolus, larger cymbium flange and thicker, bar-shaped retrolateral tibial apophysis (Fig. 5A-D ; see fig. 12B-D in Wanless (1978)); from those of P. assamensis , P. erlangping sp. nov., P. fimbriata , P. labiata , P. orientalis , P. quei , P. taiwanica , and P. zhaoi by the tegular furrow extending a membranous apophysis ventrally, the tegular apophysis obscure, and the embolus basally with a spinule (Fig. 5A-C ; see figs 10D, 7C, and 10A in Wanless (1978), fig. 6 in Murphy and Murphy 1983, fig. 661 in Peng et al. (1993), and fig. 4B in Zhang and Li (2005), respectively); in addition, from those of P. assamensis and P. fimbriata by the embolus being shortest (Fig. 5A-C ; see figs 10D and 7C in Wanless (1978)); from those of P. erlangping sp. nov. by the embolus being longer (Fig. 5A ); from those of P. labiata by the shorter cymbium flange and thicker bar-shaped retrolateral tibial apophysis (Fig. 4D ; see fig. 10B in Wanless (1978)); from those of P. orientalis , P. quei , P. taiwanica , and P. zhaoi by the longer embolus and bar-shaped retrolateral tibial apophysis (Fig. 5A-D ; see fig. 6 in Murphy and Murphy 1983, fig. 661 in Peng et al. (1993), and fig. 4B in Zhang and Li (2005), respectively). Females of P. xishan sp. nov. differ from those of P. bawang sp. nov. by having a slightly wider epigynal orifice (Fig. 5E ); from those of P. fajing sp. nov. by the larger epigyne orifice and distinctly sclerotised anterior orifice margin (Fig. 5E ); from those of P. labiata , P. quei , and P. taiwanica by the slit-like epigynal orifice (Fig. 5E ; see fig. 1C in Zhu et al. (2007), fig. 664 and 665 in Peng et al. (1993), and fig. 4F in Zhang and Li (2005), respecitively); from those of P. fimbriata and P. zhaoi by the copulatory duct being shortest (Fig. 5F ; see fig. 8D, E in Wanless (1978)).
