Type material.

Holotype: male (SYNU-Ar00016), Pool and Valley Natural Park (40°32.600'N, 116°40.687'E, elevation 574 m), Huairou District, Beijing, China, 26 April 2019, T Jiang leg. Paratypes: 2 males (SYNU-Ar00017, Ar00018, GenBank number in SYNU-Ar00017: MT843113), same data as holotype; 2 females (SYNU-Ar00019, Ar00020), same data as holotype but 23 April 2019.

Etymology.

The specific name is a patronym in honor of the collector Tongyao Jiang (IZCAS) and is a noun (name) in genitive case.

Diagnosis.

The species resembles P. lexuancanhi Yao, Pham & Li, 2012 (Figs 5 View Figure 5 , 6 View Figure 6 ; Yao et al. 2012: 313, figs 1-15) with similar bulbal apophyses (Fig. 4C View Figure 4 ) and external female genitalia (Fig. 4A View Figure 4 ), but can be easily distinguished by procursus with large, semicircular, ventral membranous process (arrowed in Fig. 3A View Figure 3 ; prolateral membranous lamella in P. lexuancanhi , arrowed 1 in Fig. 5C View Figure 5 ), small, prolateral membranous lamella provided with sawtooth (arrowed 1 in Fig. 3C View Figure 3 ; large, dorsal membranous lamella in P. lexuancanhi , arrowed 2 in Fig. 5C View Figure 5 ), and small, angular ventral sclerite provided with curved tip (arrowed in Fig. 3B View Figure 3 ; large ventral sclerite and its tip not curved in P. lexuancanhi , arrowed in Fig. 5B View Figure 5 ), by male chelicerae with pair of frontal apophyses (arrowed fa in Fig. 4D View Figure 4 ; absent in P. lexuancanhi , Fig. 6D View Figure 6 ), and by vulva with n-shaped anterior arch without median sclerite (Fig. 4B View Figure 4 ; slightly curved anterior arch with median sclerite in P. lexuancanhi , arrowed in Fig. 6B View Figure 6 ) and elliptic pore plates (Fig. 4B View Figure 4 ; oval in P. lexuancanhi , Fig. 6B View Figure 6 ). This species can also be distinguished from P. lexuancanhi by COI p-distance 0.106 between them.

Description.

Male (holotype, SYNU-Ar00016): Total length 4.75 (4.93 with clypeus), carapace 1.56 long, 1.75 wide, opisthosoma 3.19 long, 1.34 wide. Leg I: - (11.62 + 0.75 + - + - + -), leg II: 30.89 (8.50 + 0.55 + 7.84 + 12.75 + 1.25), leg III: 20.62 (6.40 + 0.60 + 5.12 + 7.60 + 0.90), leg IV: 28.58 (8.40 + 0.62 + 7.12 + 11.12 + 1.32). Distance PME-PME 0.20, diameter PME 0.12, distance PME-ALE 0.05, distance AME-AME 0.02, diameter AME 0.08. Sternum wider than long (1.04/0.96). Habitus as in Fig. 4E, F View Figure 4 . Carapace yellowish, with brown radiating marks and marginal brown bands; ocular area yellowish, with median and lateral brown bands; clypeus yellowish; sternum yellowish, with marginal brown marks. 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 spots. Ocular area elevated, without eye stalks. Thoracic furrow absent. Chelicerae (Fig. 4D View Figure 4 ) with pair of proximo-lateral apophyses, pair of distal apophyses provided with two teeth each, and pair of frontal apophyses. Pedipalps as in Fig. 3A, B View Figure 3 ; trochanter with long, retrolaterally strongly bulged ventral apophysis; femur with indistinct ventral protuberance; tibia with prolatero-ventral projection; procursus simple proximally but complex distally, with large, semicircular, ventral membranous process (arrowed in Fig. 3A View Figure 3 ), small, prolateral membranous lamella with sawtooth (arrowed 1 in Fig. 3C View Figure 3 ), small, angular ventral sclerite with curved tip (arrowed in Fig. 3B View Figure 3 ), spine-shaped prolateral apophysis (arrowed 2 in Fig. 3C View Figure 3 ), and dorsal spine (arrowed in Fig. 3D View Figure 3 ); bulb with short curved ‘pseudo-appendix’ (arrowed in Fig. 4C View Figure 4 ); uncus with scaly edge (Fig. 4C View Figure 4 ); embolus weakly sclerotized, with some transparent distal projections (Fig. 4C View Figure 4 ). Legs with short vertical setae on tibiae, metatarsi, and tarsi, without spines or curved setae.

Female (paratype, SYNU-Ar00019): Similar to male, habitus as in Fig. 4G, H View Figure 4 . Total length 5.31 (5.56 with clypeus), carapace 1.43 long, 1.14 wide, opisthosoma 3.88 long, 2.43 wide; tibia I: 5.90; tibia I L/d: 54. Distance PME-PME 0.18, diameter PME 0.12, distance PME-ALE 0.04, distance AME-AME 0.03, diameter AME 0.08. Sternum wider than long (1.07/0.83). Clypeus brown. External female genitalia (Fig. 4A View Figure 4 ) curved posteriorly, with short knob. Vulva (Fig. 4B View Figure 4 ) with sclerotized, n-shaped anterior arch and pair of elliptic pore plates. Retrolateral trichobothrium of tibia I at 4% proximally; tarsus I with 22 distinct pseudosegments.

Variations.

Ventral membranous process on procursus nearly crescent-shaped (arrowed 3 in Fig. 3C View Figure 3 ) in one paratype male (SYNU-Ar00017). Leg I missing in two paratype males (SYNU-Ar00017, Ar00018), total length 5.36 (5.52 with clypeus) in SYNU-Ar00017, total length 4.50 (4.60 with clypeus) in SYNU-Ar00018. Tibia I in another paratype female (SYNU-Ar00020): 5.75.
