Type material.

Holotype ♂: China, Tibet Autonomous Region, Nyingchi Prefecture, Chayu County, Walong, 28°35.092'N, 98°07.384'E, 3680 m, VIII 2013, J. Liu.

Etymology.

The specific name refers to the type locality; adjective.

Diagnosis.

Medium-sized Pseudopoda  species. Male resembles P. gongschana  Jäger & Vedel, 2007 (see Jäger and Vedel 2007: 6, figs 10-15) and P. platembola  Jäger, 2001 (see Jäger 2001: 57, figure 35 a–e) by: 1. embolus sickle-shaped, tapering very moderately (Figure 2A); 2. dRTA well developed and finger-like, curving distally (Figure 1 A–C). It can be distinguished from the two congeners by the following combination of characters: 1. embolic projection near the tip of embolus, making the tip look somewhat incised (Figure 1A; embolic projection absent in P. platembola  ); 2. embolus curving more intensely than in P. gongschana  (Figure 2A).

Description.

Male (holotype). Body length 10.7, DS length 4.3, DS width 4.1, OS length 6.4, OS width 3.4. Eyes: AME 0.16, ALE 0.24, PME 0.16, PLE 0.30, AME- AME 0.20, AME-ALE 0.10, PME-PME 0.33, PME-PLE 0.33, AME-PME 0.41, ALE-PLE 0.33, CH AME 0.32, CH ALE 0.24. Leg formula: II-I-IV-III. Spination: palp 131, 101, 2111; legs: femur I-III 323, IV 331; patella I-IV 001; tibia I-IV 2126; metatarsus I-II 2024, III 3025, IV 3037. Measurements of palp and legs: palp - (-, 1.0, 1.4, -, 2.4), leg I 26.3 (7.0, 2.5, 7.0, 7.5, 2.3), leg II 28.3 (7.5, 2.5, 8.0, 8.0, 2.3), leg III 23.2 (6.8, 2.3, 6.1, 6.1, 1.9), leg IV 25.7 (7.0, 2.1, 6.8, 7.5, 2.3). Promargin of chelicerae with three teeth, retromargin with four teeth. Cheliceral furrow with ca. 15 denticles.

Palp as in diagnosis. Cymbium distally slender and elongated, with a small retrobasal projection in ventral view. RTA arising basally to mesially from tibia, vRTA thumb-like, shorter than dRTA (Figure 1 A–C). Sperm duct running submarginally retrolaterally in tegulum. Embolus sickle-shaped, arising from tegulum at 10 o’clock position. The embolus tapering and very moderately curved. Embolic projection emerging at the prolateral margin of embolus as a blunt hump. Conductor arising from tegulum at 12 o’clock position, slightly leaning prolaterally and covering the tip of embolus (Figure 2A, B).

Coloration in ethanol: carapace yellow. Radial furrows and fovea dark brown. Dorsal opisthosoma brown with black pattern. Legs yellowish brown, with reddish brown dots and patches (Figure 2C, D).

Female. Unknown.
