Figs 19–20
Type material. Holotype: male, Qingyun Cave (29°29.087′N, 117°37.222′E, elevation 309 m), Gutanlingyuan Scenic Spot, Wuyuan, Jiangxi, China, 20 May 2013, Y. Luo and J. Liu leg. Paratypes: 1 male and 2 females, same data as holotype.
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. 20 D), embolus (Fig. 20 C) and epigynum (Fig. 20 A) but can be distinguished by the presence of a membranous, fringed prolateral process and a sclerotized, hooked prolateral apophysis subdistally on the procursus (arrows in Fig. 19 C), by the blunt branch on the appendix medially (Fig. 20 C), and by the long elliptic vulval pore plates (Fig. 20 B).
Description. Male (holotype): Total length 4.19 (4.82 with clypeus), carapace 1.25 long, 1.41 wide, opisthosoma 2.94 long, 1.19 wide. Leg I: 44.36 (10.78 + 0.76 + 10.83 + 19.03 + 2.96), leg II: 29.63 (7.79 + 0.61 + 7.79 + 11.83 + 1.61), leg III: 19.45 (5.47 + 0.72 + 4.78 + 7.23 + 1.25), leg IV: 20.23 (5.77 + 0.63 + 4.83 + 7.83 + 1.17); tibia I L/d: 87. Distance PME-PME 0.24; diameter PME 0.13; distance PME-ALE 0.03; distance AME- AME 0.06; diameter AME 0.08. Sternum wider than long (0.94/0.84). Habitus as in Figs 20 E–F. Carapace yellowish, with brown marks extending to ocular area; ocular area yellowish, with brown marks; sternum yellowish with brown marks. Legs yellowish, femora (subdistally) and tibiae (subproximally and subdistally) with darker rings. Opisthosoma yellowish, with little and small spots dorsally. Ocular area elevated; without eye-stalks (as in P. gonggarensis sp. nov., cf. Fig. 27 C). Thoracic furrow absent. Chelicerae as in Fig. 20 D, with a pair of proximo-lateral apophyses, a pair of black distal apophyses, and a pair of frontal apophyses. Pedipalps as in Figs 19 A–B; trochanter with a ventral apophysis; femur with a dorsal apophysis proximally and a distinct ventral ridge; tibia with an indistinct projection prolaterally; procursus simple proximally but complex distally, with a membranous, fringed prolateral process and a sclerotized, hooked prolateral apophysis subdistally (arrows in Fig. 19 C); uncus with a scaly edge; appendix hooked, with a blunt branch medially; embolus weakly sclerotized, with some nearly transparent projections distally. Retrolateral trichobothrium of tibia I at 6%; legs with short vertical setae on tibiae, metatarsi and tarsi; without spines and curved setae; tarsus I with 23 distinct pseudosegments.
Female: Similar to male, habitus as in Figs 20 G–H. Total length 4.24 (4.67 with clypeus), carapace 1.21 long, 1.32 wide, opisthosoma 3.03 long, 1.41 wide; tibia I: 8.01; tibia I L/d: 43. Distance PME-PME 0.22; diameter PME 0.07; distance PME-ALE 0.05; distance AME-AME 0.05; diameter AME 0.07. Sternum wider than long (0.90/ 0.81). Opisthosoma yellowish, with many small spots dorsally. Epigynum (Fig. 20 A) with distinct a knob. Vulva (Fig. 20 B) with a sclerotized anterior arch and two long elliptic pore plates.
Distribution. China (Jiangxi, type locality; Fig. 28).
Natural History. The species was found on the wall in the entrance zone of the cave.
