Etymology. The species name is derived from the type locality; adjective.

Diagnosis. The new species is similar to P. zhouyun ( Wang et al., 2015: 459–460, figs 11–12) in having a similar embolus, but can be distinguished from the latter by: 1) shorter CD (long in the latter); 2) larger COs (small in the latter); 3) RTA sharp apically (blunt in the latter).

Description. Male ( Fig. 9A ). Total length 2.60–2.62 (n=2). Holotype: body 2.62 long; carapace 1.21 long, 1.02 wide; abdomen 1.26 long, 0.85 wide. Carapace yellow, anteriorly abruptly narrow; fovea longitudinal, distinct. Eyes sizes and interdistances: AME 0.06, ALE 0.07, PME 0.03, PLE 0.05; AME– AME 0.02, AME–ALE 0.01, PME–PME 0.06, PME–PLE 0.06. MOA 0.15 long, front 0.12 wide, back 0.15 wide. Clypeus 0.09 high. Chelicerae with two strong anterior bristles; promargin with three well-separated teeth and retromargin with five teeth close to each other. Labium and gnathocoxae wider than long, yellow.

Legs light yellow. Measurements of legs: leg I 4.20 (1.14, 0.34, 1.19, 1.02, 0.51), II 3.41 (0.90, 0.27, 0.91, 0.85, 0.48), III 3.10 (0.87, 0.31, 0.61, 0.82, 0.49), IV 4.39 (1.16, 0.30, 1.01, 1.25, 0.67). Leg formula: 4123. Femora I–IV basally with one dorsal spine, femur I with three prolateral spines and femur II with one prolateral spine; tibia I with six pairs of ventral spines, tibia II with six proventral spines and five retroventral spines; metatarsus I with four proventral spines and three retroventral spines, metatarsus II with four proventral spines and three retroventral spines. Abdomen oval, anterior half with a small dorsal scutum, posterior half grey in color and with several chevron-like stripes dorsally.

Palp ( Figs 9C–F , 10A–C ). Femur distally with an apophysis retroventrally. RTA with a wide base and a sharp tip, extending distally, DTA broad proximally, needle-like apically. Cymbium ventrally with several hairs around the embolus tip. Embolus sharp apically. Conductor membranous, with its tip close to the end of embolus.

Female ( Fig. 9B ). Total length 2.86–2.97 (n=4). One paratype: body 2.97 long; carapace 1.24 long, 1.03 wide; abdomen 1.62 long, 0.99 wide.

MOA 0.16 long, front 0.13 wide, back 0.16 wide. Clypeus 0.08 high. Leg measurements: I 4.04 (1.09, 0.35, 1.14, 0.99, 0.47); II 3.42 (0.99, 0.27, 0.87, 0.81, 0.48); III 3.01 (0.84, 0.24, 0.63, 0.77, 0.53); IV 4.48 (1.19, 0.38, 1.01, 1.18, 0.72). Leg formula: 4123. Femora I –IV with one dorsal spine. Femur I with three prolateral spines and femur II with one prolateral spine; tibia I with six pairs of ventral spines, tibia II with six proventral spines and five retroventral spines; metatarsus I with four proventral spines and three retroventral spines, metatarsus II with four proventral spines and three retroventral spines. Abdomen light grey dorsally .

Epigyne ( Figs 9G–H , 10D–E ). CO large relatively, located with a little longer distance from each other than its diameter. Thin and short CD connecting with two transparent, oval BU. Spermathecae small, posteriorly.

Distribution. China (Sichuan).
