Etymology. The specific epithet is taken from its similarity to P. annulus Zhou et al., 2013 ; adjective.

Diagnosis. The new species is similar to P. annulus ( Zhou et al., 2013: 5–6, figs 4–6) in having a similar embolus and conductor, but can be distinguished from it by: 1) bifid PTA long relatively, the thick one with several small denticles apically (smooth in the latter); 2) distance between CO and epigastric furrow bigger than the latter; 3) epigastric plate relatively longer (short in the latter).

Description. Male ( Fig. 7A View Figure 7 ). Total length 2.72–3.07 (n=7). Holotype: body 2.86 long; carapace 1.41 long, 1.19 wide; abdomen 1.31 long, 0.98 wide. Carapace light brown, anteriorly abruptly narrow; fovea longitudinal, distinct. Eyes sizes and interdistances: AME 0.08, ALE 0.10, PME 0.06, PLE 0.09; AME– AME 0.04, AME–ALE 0.01, PME–PME 0.11, PME–PLE 0.07. MOA 0.34 long, front 0.21wide, back 0.21 wide. Clypeus 0.10 high. Chelicerae with two strong anterior bristles; promargin with three well-separated teeth and retromargin with six teeth close to each other. Labium and gnathocoxae wider than long, yellow. Legs light yellow. Measurements of legs: leg I 4.83 (1.35, 0.34, 1.52, 1.17, 0.45), II 3.84 (1.14, 0.32, 1.01, 0.89, 0.48), III 3.28 (0.86, 0.29, 0.69, 0.91, 0.53), IV 4.99 (1.42, 0.34, 1.07, 1.41, 0.75). 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 pairs of ventral spines, metatarsus II with four proventral spines and three retroventral spines. Abdomen oval, dark grey, anterior half with a big, grey dorsal scutum, posterior half with several chevron-like stripes dorsally.

Palp ( Figs 7C–E View Figure 7 , 8A–C View Figure 8 ). Femur with a ventral apophysis retrolaterally. Bifid PTA long relatively, the thick with several small denticles apically. RTA extending forward, with broad base and sharp tip. Embolus long and sharp, anteriorly located and extending retro-anteriorly. Conductor membranous and small, with its tip close to the end of embolus.

Female ( Fig. 7B View Figure 7 ). Total length 3.16–3.72 (n=6). One paratype: body 3.63 long; carapace 1.48 long, 1.34 wide; abdomen 2.12 long, 1.38 wide. Carapace light brown anteriorly; fovea longitudinal. Eyes sizes and interdistances: AME 0.09, ALE 0.11, PME 0.05, PLE 0.08; AME–AME 0.04, AME–ALE 0.02, PME– PME 0.13, PME–PLE 0.08. MOA 0.36 long, front 0.20 wide, back 0.23 wide. Clypeus 0.11 high. Leg measurements: I 5.29 (1.42, 0.39, 1.63, 1.33, 0.52); II 4.20 (1.10, 0.45, 1.11, 0.98, 0.56); III 3.81 (0.97, 0.34, 0.85, 0.94, 0.71); IV 5.38 (1.46, 0.45, 1.13, 1.56, 0.78). Leg formula: 4123. Femora I–IV with one dorsal spine. Femur I with three prolateral spines and femur II with one prolateral spines; tibia I with six pairs of ventral spines, tibia II with six pairs of ventral spines; metatarsus I with four pairs of ventral spines, metatarsus II with four proventral spines and three retroventral spines. Abdomen light grey dorsally with several chevron-like stripes dorsally.

Epigyne ( Figs 7F–G View Figure 7 , 8D–E View Figure 8 ). COs small relatively, close to each other. Thick CD, connecting with two big transparent, kidney-shaped BU anteriorly. Spermathecae complex, located behind CD, posteriorly.
