Type material.

Holotype ♂ (SYNU-Ar00378) and paratypes 1♂ (IAECAS-Ar00379Y) 2♀ (SYNU-Ar00380, IAECAS-Ar00381Y), China, Henan, Pingdingshan, Lushan County (33°46.72'N, 112°16.03'E, 743 m elev.), 17/07/2022.

Etymology.

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

Diagnosis.

The new species resembles P. parayichengicus Zhang & Zhu, 2009 ( Yao and Li 2012: 29, figs 140A-D, 141A-C) by having similar male chelicerae and epigyne (Fig. 9A, D View Figure 9 ), but can be distinguished by distal membranous process of procursus wide (Fig. 8C View Figure 8 vs. narrow), by ventro-subdistal apophysis of procursus spine-shaped (Fig. 8C View Figure 8 vs. hooked), uncus latero-medially strongly protruding (Fig. 9C View Figure 9 vs. latero-proximally slightly protruding) and by vulval anterior arch nearly half-round and posteriorly sclerotised (Fig. 9B View Figure 9 vs. crescent-shaped and entirely sclerotised).

Description.

Male (holotype). Total length 5.06 (5.19 with clypeus), carapace 1.54 long, 1.73 wide, opisthosoma 3.52 long, 1.43 wide. Leg I: 38.44 (9.81, 0.69, 9.60, 15.96, 2.38), leg II: 26.47 (7.44, 0.64, 6.47, 10.32, 1.60), leg III: 18.94 (5.58, 0.60, 4.55, 6.99, 1.22), leg IV: 26.04 (7.29, 0.62, 6.41, 10.26, 1.46); tibia I L/d: 60. Eye interdistances and diameters: PME-PME 0.23, PME 0.16, PME-ALE 0.06, AME-AME 0.05, AME 0.10. Sternum width/length: 1.10/0.88. Habitus as in Fig. 9E, F View Figure 9 . Carapace yellowish, with brown radiating marks and marginal brown bands; ocular area yellowish, with 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. 9D View Figure 9 ) with pair of proximo-lateral apophyses, pair of distal apophyses with two teeth each and pair of frontal apophyses. Palp as in Fig. 8A, B View Figure 8 ; trochanter with long (4 times longer than wide), retrolaterally strongly bulged ventral apophysis; femur with small retrolatero-proximal apophysis and distinct ventral protuberance; tibia with prolatero-ventral protuberance; procursus (Fig. 8C, D View Figure 8 ) simple proximally, but complex distally, with raised prolatero-subdistal membranous edge bearing distal membranous process, sclerotised prolatero-subdistal apophysis, sclerotised retrolatero-distal apophysis, spine-shaped ventro-subdistal apophysis and three strong and one slender dorsal spines; uncus (Fig. 9C View Figure 9 ) latero-medially protruding, with proximal apophysis and distal scaly edge; appendix (Fig. 9C View Figure 9 ) hooked, with angular median branch; embolus (Fig. 9C View Figure 9 ) weakly sclerotised, with some indistinct transparent distal projections. Retrolateral trichobothrium on tibia I at 6% proximally; legs with short vertical setae on tibiae, metatarsi and tarsi; tarsus I with 42 distinct pseudosegments.

Female (paratype). Similar to male, habitus as in Fig. 9G, H View Figure 9 . Total length 4.60 (4.75 with clypeus), carapace 1.47 long, 1.62 wide, opisthosoma 3.13 long, 1.58 wide; tibia I: 7.45; tibia I L/d: 47. Eye interdistances and diameters: PME-PME 0.22, PME 0.15, PME-ALE 0.06, AME-AME 0.04, AME 0.08. Sternum width/length: 1.05/0.73. Ocular area with median and lateral brown bands. Epigyne (Fig. 9A View Figure 9 ) nearly trapezoid, laterally strongly sclerotised, with wedge-shaped knob. Vulva (Fig. 9B View Figure 9 ) with nearly half-round, posteriorly sclerotised anterior arch and pair of anteriorly blunt and posteriorly pointed pore plates.

Variation.

Leg I missing in paratype male. Tibia I in another paratype female: 7.30.

Habitat.

Underside of overhang on rocky cliffs in the mountain area.
