Type material. Holotype: male, Tianmushan Scenic Spot (30°20′N, 119°30′E), Tianmushan Town, Linan, Zhejiang, China, 13–17 August 2014, Y. Tong leg. Paratype: 1 female, same data as holotype. Etymology. The specific name refers to the type locality; adjective.
Diagnosis. This species resembles P. saaristoi Zhang & Zhu, 2009 (see Zhang & Zhu 2009: 75, fig. 42 and Yao & Li 2012: 31, figs 149–150) in with male chelicerae (Fig. 24 D), uncus (Fig. 24 C) and epigynum (Fig. 24 A) but can be distinguished by the very thick subdistal sclerite on the procursus (arrow in Fig. 23 C), by the presence of an angular branch medially on the appendix (Fig. 24 C), by the elliptic pore plates and by the absence of lateral outgrowths on the vulva (Fig. 24 B).
Description. Male (holotype): Total length 4.42 (4.55 with clypeus), carapace 0.81 long, 0.98 wide, opisthosoma 3.44 long, 0.65 wide. Legs missing. Distance PME-PME 0.29; diameter PME 0.14; distance PME- ALE 0.10; distance AME-AME 0.11; diameter AME 0.08. Sternum wider than long (1.21/0.94). Habitus as in Figs 24 E–F. Carapace yellowish, with dark brown radiating marks extending to ocular area, ocular area brown; sternum brown. Opisthosoma yellowish, with spots dorsally and laterally. Ocular area elevated, without eye-stalks (as in P. gonggarensis sp. nov., cf. Fig. 27 C). Thoracic furrow absent. Chelicerae as in Fig. 24 D, with a pair of proximomedial apophyses, a pair of black distal apophyses, and a pair of frontal apophyses. Pedipalps as in Figs 23 A–B; trochanter with a ventral apophysis; femur with two distinct ventral ridge; tibia with a projection prolaterally; procursus simple proximally but complex distally, with a very thick subdistal sclerite (arrow in Fig. 23 C); uncus with a scaly edge; appendix hooked, with an angular branch medially; embolus weakly sclerotized, with some nearly transparent projections distally. Legs with short vertical setae on tibiae, metatarsi and tarsi; without spines and curved setae.
Female: Similar to male, habitus as in Figs 24 G–H. Total length 4.74 (4.86 with clypeus), carapace 1.42 long, 1.60 wide, opisthosoma 3.32 long, 1.68 wide. Leg I: – (8.33+ 0.70 + 9.43+ 8.33 + –), leg II: 23.96 (7.05 + 0.63 + 5.90 + 8.97 + 1.41), leg III: 18.13 (5.00 + 0.63 + 4.49 + 6.86 + 1.15), leg IV: 23.47 (6.73 + 0.64 + 5.78 + 8.94 + 1.38); tibia I: 9.43; tibia I L/d: 59. Distance PME-PME 0.24; diameter PME 0.12; distance PME-ALE 0.04; distance AME-AME 0.05; diameter AME 0.09. Sternum wider than long (1.05/0.88). Legs yellowish, distal part of femora and tibiae whitish, femora (subdistally) and tibiae (subproximally and subdistally) with darker rings. Epigynum (Fig. 24 A) dark with a knob. Vulva (Fig. 24 B) with a sclerotized anterior arch and two elliptic pore plates.
Distribution. China (Zhenjing, type locality; Fig. 28).
Natural History. The species was found on the rock walls.
