Type material. Holotype: male, Difeng Scenic Spot (30°43′N, 109°27′E), Xinglong Town, Fengjie County, Chongqing, China, 23 October 2014, Y. Tong leg.
Etymology. The specific name refers to the type locality; adjective.
Diagnosis. This species resembles P. taibaiensis Wang & Zhu, 1992 (see Huber 2011b: 451, figs 2097–2099, 2124–2125, 2178–2183, 2185, 2189 and Yao & Li 2012: 34, figs 169–170) with similar male chelicerae (Fig. 12 B) and bulbal apophyses (Fig. 12 A) but can be distinguished by the strongly curved apophysis on male pedipalpal trochanter (Fig. 11 B), by the absence of prolatero-dorsal spines on the procursus (Fig. 11 C) and by the presence of a large sclerotized retrolateral apophysis distally on the procursus (arrow in Fig. 11 C).
Description. Male (holotype): Total length 4.33 (4.52 with clypeus), carapace 1.36 long, 1.56 wide, opisthosoma 2.97 long, 1.13 wide. Leg I: 44.12 (10.58 + 0.61 + 11.05 + 19.42 + 2.64), leg II: 28.92 (7.72 + 0.76 + 7.16 + 11.63 + 1.65), leg III: 19.30 (5.65 + 0.61 + 4.66 + 7.28 + 1.10), leg IV: 26.34 (7.66 + 0.61 + 6.44 + 10.13 + 1.50); tibia I L/d: 76. Distance PME-PME 0.32; diameter PME 0.11; distance PME-ALE 0.05; distance AME- AME 0.08; diameter AME 0.07. Sternum wider than long (0.98/0.81). Habitus as in Figs 12 C–E. Carapace whitish, with brown radiating marks and brown bands marginally; ocular area whitish, with brown marks; sternum brown, with whitish marks medially. Legs yellowish, patellae, and proximal parts of tibiae and metatarsi yellow, femora (subdistally) and tibiae (subdistally) with slightly darker rings. Opisthosoma whitish, with small 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. 12 B, with a pair of proximo-lateral apophyses, a pair of black distal apophyses, and a pair of frontal apophyses. Pedipalps as in Figs 11 A–B; trochanter with a ventral apophysis; femur with a distinct ventral ridge; tibia with a projection prolaterally; procursus simple proximally but complex distally, with a sclerotized retrolateral apophysis distally (arrow in Fig. 11 C); uncus with a scaly edge; appendix curved, with a branch medially; embolus weakly sclerotized, with some nearly transparent projections distally. Retrolateral trichobothrium of tibia I at 5%; legs with short vertical setae on tibiae, metatarsi and tarsi; without spines and curved setae; tarsus I with 23 distinct pseudosegments.
Female: Unknown.
Distribution. China (Chongqing, type locality; Fig. 28).
Natural History. The species was found on the rock walls.
