Type material.
Holotype: China • ♂; Sichuan, Aba, Li County, Xindianzi ; 31.528726 ° N, 103.254276 ° E; alt. 1606 m; 19 May 2024; X. Zhang, Y. Wang & Q. Meng leg.; SYNU -Ar 00474 GoogleMaps . Paratypes: China • 1 ♂; same data as for the holotype; SYNU -Ar 00475 GoogleMaps • 2 ♀; same data as for the holotype; SYNU -Ar 00476 –77 GoogleMaps .
Etymology.
The specific name refers to the type locality; noun in apposition.
Diagnosis.
The new species resembles P. langensis Yao & Li, 2016 ( Dong et al. 2016 b: 8, figs 5 A – D, 6 A – H) by having similar uncus (Figs 5 C View Figure 5 , 14 B View Figure 14 ), male chelicerae (Fig. 5 D View Figure 5 ) and epigyne (Fig. 5 A View Figure 5 ), but can be distinguished by procursus with raised, sclerotized, swollen prolatero-subdistal edge (arrow 6 in Fig. 4 D View Figure 4 vs prolatero-subdistal edge not swollen), sclerotized retrolatero-distal apophysis (arrow 2 in Fig. 4 B View Figure 4 ; arrow 1 in Fig. 4 D View Figure 4 vs absent) and distal membranous process without sawteeth (arrow 2 in Fig. 4 C View Figure 4 vs present), by appendix without median apophyses (a in Figs 5 C View Figure 5 , 14 B View Figure 14 vs with sawtooth median apophyses), and by vulval pore plates longer than wide (pp in Fig. 5 B View Figure 5 vs wider than long).
Description.
Male (holotype): Measurements: Total length 3.90 (4.03 with clypeus), carapace 1.12 long, 1.25 wide, opisthosoma 2.78 long, 1.24 wide. Leg I: 24.32 (6.28, 0.52, 6.41, 9.23, 1.88), leg II: 16.59 (4.70, 0.51, 4.25, 6.03, 1.10), leg III: 12.47 (3.72, 0.49, 3.09, 4.35, 0.82), leg IV: 15.81 (4.80, 0.50, 4.16, 5.32, 1.03); tibia I L / d: 51. Eye interdistances and diameters: PME – PME 0.20, PME 0.13, PME – ALE 0.03, AME – AME 0.04, AME 0.07. Sternum width / length: 0.89 / 0.74.
Color: Carapace yellowish, with median brown marks and marginal brown bands; ocular area yellowish; clypeus yellowish, with brown marks; sternum brown. Legs yellowish, but brownish 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 light dorsal and lateral spots.
Body: Habitus as in Fig. 5 E, F View Figure 5 ; ocular area elevated, without eye-stalks.
Chelicerae: As in Fig. 5 D View Figure 5 , with pair of proximo-lateral apophyses, pair of distal apophyses with two teeth each, and pair of frontal apophyses.
Palp: As in Fig. 4 A, B View Figure 4 ; trochanter with long (3 × longer than wide), retrolaterally strongly bulged ventral apophysis; femur with retrolatero-proximal protrusion (arrow 1 in Fig. 4 B View Figure 4 ) and distinct ventral protrusion; procursus simple proximally but complex distally, with raised, sclerotized, swollen prolatero-subdistal edge bearing membranous part (arrow 6 in Fig. 4 D View Figure 4 ; arrow 1 in Fig. 4 C View Figure 4 ), distal membranous process (arrow 2 in Fig. 4 C View Figure 4 ), sclerotized retrolatero-distal apophysis (arrow 1 in Fig. 4 D View Figure 4 ; arrow 2 in Fig. 4 B View Figure 4 ), and one slender and three strong dorsal spines (arrows 2–5 in Fig. 4 D View Figure 4 ); uncus with scales, proximal apophysis, and distinct latero-median protrusion (arrow in Fig. 5 C View Figure 5 ; arrows 1, 2 in Fig. 14 B View Figure 14 ); appendix T-shaped (Figs 5 C View Figure 5 , 14 B View Figure 14 ); embolus weakly sclerotized, with some transparent distal projections (Figs 5 C View Figure 5 , 14 B View Figure 14 ).
Legs: Retrolateral trichobothrium on tibia I at 6 % proximally; legs with short vertical setae on tibiae, metatarsi, and tarsi; tarsus I with 27 distinct pseudosegments.
Female (paratype, SYNU -Ar 00476 ): Similar to male, habitus as in Fig. 5 G, H View Figure 5 . Total length 4.05 (4.18 with clypeus), carapace 1.08 long, 1.25 wide, opisthosoma 2.97 long, 1.82 wide; tibia I: 5.96; tibia I L / d: 46. Eye interdistances and diameters: PME – PME 0.17, PME 0.13, PME – ALE 0.03, AME – AME 0.04, AME 0.06. Sternum width / length: 0.82 / 0.76. Epigyne nearly triangular, laterally strongly sclerotized, with knob (Fig. 5 A View Figure 5 ). Vulva with curved, posteriorly sclerotized anterior arch and pair of nearly round pore plates (Fig. 5 B View Figure 5 ).
Variation.
Tibia I in paratype male ( SYNU -Ar 00475 ): 6.92. Tibia I in another paratype female ( SYNU -Ar 00477 ): 6.41.
Habitat.
Underside of overhang on rocky cliffs in the mountain area.
Distribution.
