Etymology. The species name is taken from its similarity to P. nigerus Yin, 2012 ; noun.

Diagnosis. The female of the new species is similar to P. nigerus (Yin, 2012: 1078, fig. 565) in having bursae, but can be distinguished from it by: 1) CO rather half-round openings (completely round openings in the latter); 2) the distance between copulatory ducts shorter (longer in the latter). The male of the new species is similar to P. festivus (C. L. Koch, 1835) ( Wang et al., 2015: 463, fig. 15) in having a similar bulb, but can be distinguished from it by: 1) with two retrolateral tibial apophyses, thin (only a single thick one in the latter); 2) BU smaller (large in the latter); 3) two CO anteriorly (with only one, posteriorly in the latter).

Description. Male ( Fig. 13A View Figure 13 ). Total length 2.36–2.72 (n =3). Holotype: body 2.44 long; carapace 1.05 long, 0.92 wide; abdomen 1.38 long, 0.79 wide. Carapace yellowish grey, oval, abruptly narrow anteriorly, medium grey; thoracic part slightly higher than the cephalic part; fovea longitudinal, distinct. Eyes sizes and interdistances: AME 0.06, ALE 0.08, PME 0.05, PLE 0.07; AME–AME 0.03, AME–ALE 0.01, PME–PME 0.06, PME–PLE 0.04. MOA 0.17 long, front 0.15 wide, back 0.16 wide. Clypeus 0.08 high. Chelicerae light brown, with two bristles anteriorly; promargin of cheliceral furrow with three well-separated teeth and retromargin with two teeth near to each other. Labium and gnathocoxae brown. Legs and palps yellowish. Leg measurements: I 3.04 (0.79, 0.29, 0.83, 0.71, 0.42); II 2.62(0.73, 0.23, 0.63, 0.60, 0.43); III 2.27 (0.48, 0.24, 0.60, 0.54, 0.41); IV 3.68 (0.97, 0.31, 0.91, 0.94, 0.55). Leg formula: 4123. Femora I–IV with only one dorsal spine. Femur I and femur II without prolateral spines; tibia I and tibia II with six pairs of ventral spines; metatarsus I and metatarsus II with four proventral spines and three retroventral spines. Abdomen dark grey, dorsum with a small white spot posteriorly.

Palp ( Figs 13C–E View Figure 13 , 14A–C View Figure 14 ). Femoral apophysis located ventrally. Two retrolateral tibial apophyses with the same length. Embolus long.

Female ( Fig. 13B View Figure 13 ). Total length 2.87–3.14 (n =4). One female body 3.14 long; carapace 1.16 long, 0.98 wide; abdomen 1.75 long, 1.14 wide. Carapace dark brown, abruptly narrow anteriorly; fovea longitudinal. Diameter of eyes: AME 0.07, ALE 0.09, PME 0.05, PLE 0.06.

Leg measurements (one specimen): I 3.60 (0.91, 0.32, 1.01, 0.89, 0.47); II 3.14 (0.85, 0.28, 0.75, 0.76, 0.50); III 2.79 (0.76, 0.29, 0.59, 0.67, 0.48); IV 3.89 (0.96, 0.32, 0.99, 0.98, 0.64). Leg formula: 4123. Femora I–IV with one dorsal spine. Femur I and femur II without prolateral spine; tibia I–II with six pairs of ventral spines; metatarsus I and metatarsus II with four proventral spines and three retroventral spines. Abdomen dark dorsally.

Epigyne ( Figs 13F–G View Figure 13 , 14D–E View Figure 14 ). Copulatory openings large, situated medially, located in the shallow concavities anteriorly ( Figs 13F View Figure 13 , 14D View Figure 14 ). Vulva anteriorly with a pair of small, ear-like bursae, posteriorly with a pair of spermathecae. Glandular appendage much shorter than fertilization duct.
