Type material.
Holotype ♂ (SYNU-Ar00403) and Paratypes 1♂ (SYNU-Ar00404) 2♀ (SYNU-Ar00405-06), China, Shaanxi, Baoji, Long County, Xinjichuan Town, Longmendong Scenic Spot (35°2.33'N, 106°40.22'E, 1489 m elev.), 29 July 2022, Z. Yao, L. Yang & L. Zhang leg.
Etymology.
The specific name refers to the type locality and is a noun in apposition.
Diagnosis.
The species resembles P. ankang sp. nov. with similar male chelicerae and uncus (Fig. 6C, D View Figure 6 ), but it can be distinguished by raised prolatero-subdistal membranous edge of procursus laterally rectangular (arrow 3 in Fig. 5D View Figure 5 ; laterally angular in P. ankang sp. nov., arrow 3 in Fig. 3D View Figure 3 ), by appendix with slender median branch (same length as appendix, arrow 2 in Fig. 6C View Figure 6 ; angular median branch in P. ankang sp. nov., arrow 2 in Fig. 4C View Figure 4 ), by epigynal plate nearly triangular and posteriorly straight (Fig. 6A View Figure 6 ; posteriorly strongly curved in P. ankang sp. nov., Fig. 4A View Figure 4 ) and by vulval pore plates relatively close to each other (Fig. 6B View Figure 6 ; widely separated in P. ankang sp. nov., Fig. 4B View Figure 4 ).
Description.
Male (holotype): Total length 4.96 (5.05 with clypeus), carapace 1.48 long, 1.78 wide, opisthosoma 3.48 long, 1.52 wide. Leg I: 42.86 (10.77, 0.75, 11.15, 17.56, 2.63), leg II: 28.13 (7.82, 0.70, 6.98, 10.96, 1.67), leg III missing, leg IV: 25.71 (7.69, 0.65, 6.28, 9.62, 1.47); tibia I L/d: 70. Eye interdistances and diameters: PME-PME 0.26, PME 0.16, PME-ALE 0.06, AME-AME 0.05, AME 0.12. Sternum width/length: 1.08/0.93. Habitus as in Fig. 6E, F View Figure 6 . Carapace yellowish, with brown radiating marks and marginal brown bands; ocular area yellowish, with anterior brown marks; 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. 6D View Figure 6 ) with pair of proximo-lateral apophyses, pair of distal apophyses with two teeth each and pair of frontal apophyses. Pedipalp as in Fig. 5A, B View Figure 5 ; trochanter with long (longer than wide), retrolaterally strongly bulged ventral apophysis; femur with small retrolatero-proximal apophysis and distinct ventral protuberance; tibia with prolatero-ventral projection; procursus simple proximally, but complex distally, with raised prolatero-subdistal membranous edge bearing distal membranous process (arrow 1 in Fig. 5C View Figure 5 ), sclerotised prolatero-subdistal apophysis (arrow 2 in Fig. 5C View Figure 5 ) and two strong dorsal spines (arrows 1 and 2 in Fig. 5D View Figure 5 ); uncus latero-medially protruding (arrow 1 in Fig. 6C View Figure 6 ), with proximal apophysis and distal scaly edge; appendix curved, with slender median branch (same length as appendix, arrow 2 in Fig. 6C View Figure 6 ); embolus weakly sclerotised, with some transparent distal projections (Fig. 6C View Figure 6 ). Retrolateral trichobothrium of tibia I at 8% proximally; legs with short vertical setae on tibiae, metatarsi and tarsi; tarsus I with 35 distinct pseudosegments.
Female (paratype, SYNU-Ar00405): Similar to male, habitus as in Fig. 6G, H View Figure 6 . Total length 4.75 (4.80 with clypeus), carapace 1.35 long, 1.62 wide, opisthosoma 3.40 long, 1.70 wide; tibia I: 7.10; tibia I L/d: 51. Eye interdistances and diameters: PME-PME 0.22, PME 0.15, PME-ALE 0.06, AME-AME 0.05, AME 0.11. Sternum width/length: 1.01/0.79. Epigyne (Fig. 6A View Figure 6 ) nearly triangular, laterally and medially strongly sclerotised, with column-shaped knob. Vulva (Fig. 6B View Figure 6 ) with laterally strongly curved, posteriorly sclerotised anterior arch and pair of nearly elliptic pore plates.
Variation.
Tibia I in paratype male (SYNU-Ar00404): 10.44. Tibia I in another paratype female (SYNU-Ar00406): 7.18.
Natural history.
The species was found on the underside of an overhang on rocky cliffs.
Distribution.
