Type material.

Holotype ♂ (SYNU-Ar00382) and paratypes 1♂ (IAECAS-Ar00383Y) 3♀ (SYNU-Ar00384-85, IAECAS-Ar00386Y), China, Shaanxi, Shangluo, Zhashui County, Jiutianshan Scenic Spot (33°36.93'N, 109°8.45'E, 878 m elev.), 22/07/2022.

Etymology.

The specific name refers to the type locality and is a noun in apposition.

Diagnosis.

The new species resembles P. huberi Zhang & Zhu, 2009 ( Yao and Li 2012: 19, figs 83A-D, 84A-C) by having similar male chelicerae, uncus and epigyne (Fig. 11A, C, D View Figure 11 ), but can be distinguished by prolatero-subdistal apophysis of procursus proximally thick (Fig. 10C View Figure 10 vs. thin), by prolatero-subdistal membranous edge of procursus laterally straight (Fig. 10D View Figure 10 vs. latero-medially strongly curved), by male palpal trochanteral apophysis with retrolatero-distal branch (Fig. 10A, B View Figure 10 vs. male palpal trochanteral apophysis retrolatero-medially strongly bulged, with retrolatero-median branch), by appendix with distal teeth (Fig. 11C View Figure 11 vs. absent) and by vulval anterior arch laterally strongly curved (Fig. 11B View Figure 11 vs. C-shaped).

Description.

Male (holotype). Total length 4.68 (4.90 with clypeus), carapace 1.44 long, 1.66 wide, opisthosoma 3.24 long, 1.50 wide. Leg I: 36.43 (9.55, 0.73, 9.05, 14.74, 2.36), leg II: 24.19 (7.05, 0.68, 5.95, 9.17, 1.34), leg III: 17.65 (5.15, 0.62, 4.20, 6.60, 1.08), leg IV: 23.71 (6.90, 0.65, 5.83, 9.05, 1.28); tibia I L/d: 60. Eye interdistances and diameters: PME-PME 0.24, PME 0.17, PME-ALE 0.06, AME-AME 0.07, AME 0.12. Sternum width/length: 1.08/0.86. Habitus as in Fig. 11E, F View Figure 11 . Carapace yellowish, with brown radiating marks and marginal brown bands; ocular area yellowish, with median and lateral brown bands; clypeus brown; sternum yellowish, with brown marks. Legs yellowish, but dark brown on patellae and whitish on distal parts of femora and tibiae, with darker rings on subdistal parts of femora and proximal and subdistal parts of tibiae. Opisthosoma yellowish, with dorsal and lateral spots. Chelicerae (Fig. 11D View Figure 11 ) with pair of proximo-lateral apophyses, pair of distal apophyses with two teeth each and pair of frontal apophyses. Palp as in Fig. 10A, B View Figure 10 ; trochanter with long (3 times longer than wide) ventral apophysis bearing retrolatero-distal branch; femur with small retrolatero-proximal apophysis and distinct ventral protuberance; tibia with prolatero-ventral protuberance; procursus (Fig. 10C, D View Figure 10 ) simple proximally, but complex distally, with raised prolatero-subdistal membranous edge bearing distal membranous process, sclerotised prolatero-subdistal apophysis and two strong and one slender dorsal spines; uncus (Fig. 11C View Figure 11 ) with proximal apophysis and distal scaly edge; appendix (Fig. 11C View Figure 11 ) curved, with distal teeth; embolus (Fig. 11C View Figure 11 ) weakly sclerotised, with some indistinct transparent distal projections. Retrolateral trichobothrium on tibia I at 5% proximally; legs with short vertical setae on tibiae, metatarsi and tarsi; tarsus I with 36 distinct pseudosegments.

Female (paratype). Similar to male, habitus as in Fig. 11G, H View Figure 11 . Total length 4.35 (4.52 with clypeus), carapace 1.38 long, 1.53 wide, opisthosoma 2.97 long, 1.58 wide; tibia I: 7.45; tibia I L/d: 53. Eye interdistances and diameters: PME-PME 0.19, PME 0.15, PME-ALE 0.05, AME-AME 0.05, AME 0.11. Sternum width/length: 1.02/0.80. Epigyne (Fig. 11A View Figure 11 ) nearly triangular, laterally strongly sclerotised, with cone-shaped knob. Vulva (Fig. 11B View Figure 11 ) with laterally strongly curved, sclerotised anterior arch, pair of nearly round pore plates and pair of C-shaped sclerites.

Variation.

Tibia I in paratype male: 9.15. Tibia I in the other two paratype females: 7.15, 7.60.

Habitat.

Underside of overhang on rocky cliffs in the mountain area.
