Type material.

Holotype ♂ (SYNU-Ar00363) and paratypes 2♂ (SYNU-Ar00364, IAECAS-Ar00365Y) 3♀ (SYNU-Ar00366-67, IAECAS-Ar00368Y), China, Henan, Jiaozuo, Xiuwu County, Qinglongxia Scenic Spot (35°22.05'N, 113°11.77'E, 820 m elev.), 14/07/2022.

Etymology.

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

Diagnosis.

The new species resembles P. henanensis Zhu & Mao, 1983 ( Yao and Li 2012: 18, figs 77A-D, 78A-B) by having similar male chelicerae, bulbal apophyses and epigyne (Fig. 3A, C, D View Figure 3 ), but can be distinguished by prolatero-subdistal sclerite of procursus laterally curved (Fig. 2C View Figure 2 vs. laterally flat), by procursus with distal membranous process (Fig. 2C View Figure 2 vs. absent), by retrolatero-distal apophysis of procursus distally pointed in prolateral view (Fig. 2C View Figure 2 vs. distally blunt) and by wavy vulval anterior arch (Fig. 3B View Figure 3 vs. arch-shaped).

Description.

Male (holotype). Total length 5.38 (5.58 with clypeus), carapace 1.66 long, 1.88 wide, opisthosoma 3.72 long, 1.66 wide. Leg I: 39.95 (10.25, 0.79, 9.85, 16.31, 2.75), leg II: 28.15 (7.88, 0.72, 6.95, 10.96, 1.64), leg III: 20.28 (5.90, 0.66, 4.84, 7.63, 1.25), leg IV: 26.12 (7.76, 0.67, 6.67, 9.52, 1.50); tibia I L/d: 62. Eye interdistances and diameters: PME-PME 0.26, PME 0.17, PME-ALE 0.04, AME-AME 0.04, AME 0.10. Sternum width/length: 1.25/0.86. Habitus as in Fig. 3E, F View Figure 3 . Carapace yellowish, with brown radiating marks and marginal brown bands; ocular area yellowish, with median and lateral brown bands; clypeus and 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. 3D View Figure 3 ) with pair of proximo-lateral apophyses and pair of distal apophyses. Palp as in Fig. 2A, B View Figure 2 ; trochanter with long (8 times longer than wide), retrolatero-proximally strongly bulged ventral apophysis; femur with small retrolatero-proximal apophysis and distinct ventral protuberance; tibia with prolatero-ventral protuberance; procursus (Fig. 2C, D View Figure 2 ) simple proximally, but complex distally, with raised prolatero-subdistal membranous edge, curved prolatero-subdistal sclerite, distal membranous process, sclerotised retrolatero-distal apophysis and two strong dorsal spines; uncus (Fig. 3C View Figure 3 ) distally widened, with proximal apophysis and distal scaly edge; appendix (Fig. 3C View Figure 3 ) hooked, with distal teeth; embolus (Fig. 3C View Figure 3 ) 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 38 distinct pseudosegments.

Female (paratype). Similar to male, habitus as in Fig. 3G, H View Figure 3 . Total length 5.00 (5.19 with clypeus), carapace 1.52 long, 1.70 wide, opisthosoma 3.48 long, 1.60 wide; tibia I: 8.05; tibia I L/d: 50. Eye interdistances and diameters: PME-PME 0.21, PME 0.14, PME-ALE 0.04, AME-AME 0.03, AME 0.08. Sternum width/length: 1.03/0.80. Clypeus brown. Epigyne (Fig. 3A View Figure 3 ) nearly triangular, laterally slightly sclerotised, with knob developed into long scape (10 times longer than wide). Vulva (Fig. 3B View Figure 3 ) with wavy, posteriorly sclerotised anterior arch and pair of elliptic pore plates.

Variation.

Tibia I in two paratype males: 9.55, 10.50. Tibia I in the other two paratype females: 7.95, 8.25.

Habitat.

Underside of overhang on rocky cliffs in the mountain area.
