Eye interdistances and diameters: PME – PME 0.30, PME 0.15, PME – ALE 0.05, AME – AME 0.05, AME 0.11. Sternum width / length: 1.27 / 1.09. Habitus as in Fig. 3 E and F. Carapace yellowish, with brown radiating marks and marginal brown bands; ocular area yellowish, with median and lateral brown bands; clypeus yellowish, with brown marks; sternum brown. 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 brown spots. Chelicerae with pair of proximo-lateral apophyses (pa in Fig. 3 D), pair of distal apophyses (da in Fig. 3 D) without teeth, pair of frontal apophyses (fa in Fig. 3 D) and several small median cones (arrow in Fig. 3 D). Palps as in Fig. 2 A and B; trochanter with retrolaterally strongly bulged ventral apophysis; femur with retrolatero-proximal protrusion (arrow in Fig. 2 B) and indistinct ventral protrusion; tibia with prolatero-ventral protrusion; procursus simple proximally, but complex distally, with prolatero-subdistal apophysis (arrow 1 in Fig. 2 C) bearing proximally membranous part, curved dorso-distal apophysis (arrow 2 in Fig. 2 C), ventro-subdistal membranous process (arrow 3 in Fig. 2 C) and three dorsal spines (arrows in Fig. 2 D); uncus with scales and latero-median protrusion (arrow in Fig. 3 C); appendix hooked, with swollen subdistal branch (a in Fig. 3 C); embolus slightly sclerotised, with transparent distal projections (e in Fig. 3 C). Retrolateral trichobothrium on tibia I at 5 % proximally; legs with short vertical setae on tibiae, metatarsi and tarsi; tarsus I with 33 distinct pseudosegments. Female (paratype, SYNU-Ar 00444): Similar to male, habitus as in Fig. 3 G and H. Total length 5.66 (5.85 with clypeus), carapace 1.66 long, 2.00 wide, opisthosoma 4.00 long, 1.60 wide; tibia I: 9.25; tibia I L / d: 46. Eye interdistances and diameters: PME – PME 0.26, PME 0.16, PME – ALE 0.05, AME – AME 0.06, AME 0.08. Sternum width / length: 1.16 / 0.80. Clypeus brown. Epigyne strongly sclerotised, anchor-shaped, with wedge-shaped knob (kn in Fig. 3 A). Vulva with curved, dorsally sclerotised and ventrally membranous anterior arch (aa in Fig. 3 B) and pair of nearly elliptic pore plates (3 × longer than wide, pp in Fig. 3 B). Diagnosis The species resembles P. bajia Lu, Yao & He, 2022 (Lu et al. 2022 a: 4, figs. 2 A – D and 3 A – H) by having similar male chelicerae (Fig. 3 D), but can be distinguished by dorso-distal apophysis of procursus distally curved (arrow 2 in Fig. 2 C vs. distally straight), by uncus latero-medially protruding (arrow in Fig. 3 C vs. prolatero-medially protruding), by appendix with sclerotised subdistal branch (a in Fig. 3 C vs. membranous subdistal branch), by epigynal knob approximately 4 / 5 length of epigynal plate (kn in Fig. 3 A vs. 1 / 2) and by vulval pore plates 3 × longer than wide (pp in Fig. 3 B vs. 1.5 ×). Etymology The specific name refers to the type locality; noun in apposition. Distribution China (Hebei, type locality; Fig. 1). Biology Underside of overhang on rocky cliffs in the mountain area (Fig. 1).
