Type material.

Holotype: China • ♂; Yunnan, Zhaotong, Qiaojia County, Laodian Town, Dingjia Village; 26.938345 ° N, 103.276833 ° E; alt. 1713 m; 2 Jun. 2024; X. Zhang, Y. Wang & Q. Meng leg.; SYNU -Ar 00471 . Paratypes: China • 1 ♂; same data as for the holotype; SYNU -Ar 00472 • 1 ♀; same data as for the holotype; SYNU -Ar 00473 .

Etymology.

The specific name refers to the type locality; noun in apposition.

Diagnosis.

The new species resembles P. bidentatus Zhu, Zhang, Zhang & Chen, 2005 (Yao and Li 2012: 11, figs 33 A – D, 34 A – C; Huber 2011: 420, figs 1930, 1931, 1961, 1962, 2028–2033) by having similar uncus (Figs 3 C, 14 A) and epigyne (Fig. 3 A), but can be distinguished by procursus with blunt distal apophysis (arrow 1 in Fig. 2 C vs absent) and sclerotized sawtooth apophyses (arrow 1 in Fig. 2 D vs absent), by male chelicerae with two pairs of frontal apophyses (fa in Fig. 3 D vs absent), by appendix without angular median apophyses (a in Figs 3 C, 14 A vs with two), and by vulval pore plates 2 × longer than wide (pp in Fig. 3 B vs 3 ×).

Description.

Male (holotype): Measurements: Total length 6.88 (6.99 with clypeus), carapace 1.62 long, 1.84 wide, opisthosoma 5.26 long, 1.54 wide. Leg I: 51.81 (13.46, 0.78, 12.18, 22.76, 2.63), leg II: 33.82 (9.42, 0.75, 8.40, 13.65, 1.60), leg III: 23.79 (6.64, 0.70, 5.90, 9.30, 1.25), leg IV: missing; tibia I L / d: 81. Eye interdistances and diameters: PME – PME 0.40, PME 0.20, PME – ALE 0.06, AME – AME 0.09, AME 0.09. Sternum width / length: 1.16 / 0.94.

Color: Carapace yellowish, with brown radiating marks; ocular area yellowish, with median and lateral brown bands; clypeus yellowish, with indistinct 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.

Body: Habitus as in Fig. 3 E, F; ocular area elevated, each eye triad on top of laterally directed eye-stalk.

Chelicerae: As in Fig. 3 D, with pair of proximo-lateral apophyses, pair of distal apophyses, and two pairs of frontal apophyses.

Palp: As in Fig. 2 A, B; trochanter with long (3 × longer than wide), retrolaterally bulged ventral apophysis; femur with retrolatero-proximal protrusion (arrow 1 in Fig. 2 B) and distinct ventral protrusion; procursus simple proximally but complex distally, with raised, prolatero-subdistal membranous edge bearing blunt distal apophysis (arrow 1 in Fig. 2 C) with sclerotized sawtooth apophyses, sclerotized flat apophysis and sclerotized pointed apophysis (arrows 1–3 in Fig. 2 D), retrolatero-distal membranous process (arrow 2 in Fig. 2 B, C), distal membranous process (arrow 3 in Fig. 2 C), sclerotized, proximally wide and distally pointed dorso-distal apophysis (arrow 4 in Fig. 2 D), and strong dorsal spine (arrow 5 in Fig. 2 D); uncus with scales, proximal apophysis, and distinct latero-median protrusion (arrows 1, 2 in Figs 3 C, 14 A); appendix hooked, with slender subdistal branch (arrow 3 in Figs 3 C, 14 A); embolus weakly sclerotized, with some transparent distal projections (Figs 3 C, 14 A).

Legs: Retrolateral trichobothrium on tibia I at 2 % proximally; legs with short vertical setae on tibiae, metatarsi, and tarsi; tarsus I with 42 distinct pseudosegments.

Female (paratype, SYNU -Ar 00473): Similar to male, habitus as in Fig. 3 G, H. Total length 6.46 (6.62 with clypeus), carapace 1.52 long, 1.70 wide, opisthosoma 4.94 long, 2.64 wide; leg I missing. Eye interdistances and diameters: PME – PME 0.25, PME 0.18, PME – ALE 0.04, AME – AME 0.04, AME 0.09. Sternum width / length: 1.10 / 1.03. Ocular area without eye-stalks. Epigyne nearly trapezoidal, laterally strongly sclerotized, with knob (Fig. 3 A). Vulva with curved, posteriorly sclerotized anterior arch and pair of nearly quadrilateral pore plates (Fig. 3 B).

Variation.

Unknown. Leg I missing in paratype male (SYNU -Ar 00472).

Habitat.

Underside of overhang on rocky cliffs in the mountain area.
