Type material.

Holotype ♂: China, Yunnan Province, Chuxiong City, Zixi Mountain, 25°00.602'N, 101°24.386'E, 2445 m, VI 2017, Z. Chen. Paratype: 1♀, same data as holotype.

Etymology.

The specific name refers to the type locality; adjective.

Diagnosis.

Median-sized Pseudopoda  species. Male resembles P. sinapophysis  Jäger & Vedel, 2007 (see Jäger and Vedel 2007: 3, figs 1-6) and P. mediana  Quan, Zhong & Liu, 2014 (see Quan et al. 2014: 562, figs 6 A–C, 7 A–C, 8 A–D, 9 A–C) by: embolus is curved, with its tip pointing back dorsally (Figure 35B). It can be distinguished from the two congeners by the following combination of characters: 1. cymbium short and blunt (Figure 34B; elongated and slender in P. sinapophysis  and P. mediana  ); 2. prolateral rim of embolus extended and forming an embolic projection near the tip (Figure 35A, B); 3. dRTA finger-like (Figure 34 A–C; broadened in P. mediana  ).

Female resembles P. cangschana  Jäger & Vedel, 2007 (see Jäger and Vedel 2007: 19, figs 66-72), P. gongschana  Jäger & Vedel, 2007 (see Jäger and Vedel 2007: 6, figs 10-15) and P. albolineata  Jäger, 2001 (see Jäger 2001: 83, fig. 46 a–o) in ventral view by the similar shape of lateral lobes, but can be distinguished from the three congeners by the following combination of characters: 1. lateral loops of internal duct system (spermathecae) distinct, visible in dorsal view (Figure 36B; spermatheca hidden behind first winding in P. gongschana  ); 2. first winding strongly bent (Figure 36B, E; almost straight in P. cangschana  and P. albolineata  ).

Description.

Male (holotype). Body length 10.5, DS length 5.0, DS width 4.4, OS length 5.5, OS width 3.2. Eyes: AME 0.17, ALE 0.29, PME 0.22, PLE 0.32, AME-AME 0.17, AME-ALE 0.08, PME-PME 0.26, PME-PLE 0.40, AME-PME 0.37, ALE-PLE 0.35, CH AME 0.38, CH ALE 0.30. Spination: palp 131, 101, 2111; legs: femur III 323, IV 331; patella III-IV 101; tibia III-IV 2026; metatarsus III 3025, IV 3037. Measurements of palp and legs: palp 7.3 (2.5, 1.1, 1.4, -, 2.3), leg I -, leg II -, leg III 19.6 (5.4, 2.2, 5.3, 5.1, 1.6), leg IV 21.9 (6.0, 2.1, 5.5, 6.5, 1.8). Promargin of chelicerae with three teeth, retromargin with four teeth. Cheliceral furrow with ca. 25 denticles.

Palp as in diagnosis. Cymbium sub-triangular, with distinct retrolateral bulge. RTA arising basally to mesially from tibia, vRTA humble and broad (Figure 34 A–C). Sperm duct running submarginally retrolaterally in tegulum. Embolus broad and sickle-shaped, arising from tegulum at 10 o’clock position. Conductor arising from tegulum at 12 o’clock position, leaning slightly prolaterally (Figure 35A, B).

Coloration in ethanol: carapace yellowish brown. Radial furrows and fovea dark brown. Dorsal opisthosoma reddish brown. Ventral opisthosoma with a pair of bright longitudinal lines. Legs yellowish brown, with randomly distributed reddish brown dots (Figure 35C, D).

Female (paratype). Body length 11.5, DS length 5.5, DS width 4.7, OS length 6.0, OS width 4.2. Eyes: AME 0.21, ALE 0.32, PME 0.24, PLE 0.32, AME-AME 0.25, AME-ALE 0.13, PME-PME 0.33, PME-PLE 0.50, AME-PME 0.43, ALE-PLE 0.42, CH AME 0.50, CH ALE 0.33. Spination: palp 131, 101, 2121, 1014; legs: femur II 323, III 322, IV 331; patella II-IV 001; tibia II-III 2026, IV 2025; metatarsus I-II 1014, III 3015, IV 3037. Measurements of palp and legs: palp 7.2 (2.2, 1.2, 1.6, -, 2.2), leg I - (-, -, -, 4.0, 1.6), leg II 18.5 (5.3, 2.7, 4.6, 4.3, 1.6), leg III 15.3 (4.5, 2.1,4.0, 3.4, 1.3), leg IV 17.4 (5.0, 2.0, 4.3, 4.5, 1.6). Promargin of chelicerae with three teeth, retromargin with four teeth. Cheliceral furrow with ca. 30 denticles.

Epigyne as in diagnosis. Epigynal field with nearly equal length in transverse and longitudinal axis. Anterior bands distinct, anterior margin slightly trilobate. Lateral lobes longer in longitudinal axis. Lateral lobes converged on the central axis, with both anterior and posterior part V-shaped. Spermathecae exposed in dorsal view. Spermathecae oval, with coiling ducts embedded (Figure 36B, E).

Coloration in ethanol: as in male, but generally darker (Figure 36C, D).
