Figure 22 –32

Type material. Holotype male (SWUC-T-SP-03-01), China, Chongqing Municipality, Wuxi County, YNR, Zhuanping Administrative Station , 31°29′53′′N, 109°57′18′′E, elev. 2178 m, 18 August 2022, L.Y. Wang and T. Y. Ren leg. Paratypes: 1 female (SWUC-T-SP-03-02), with same data as for holotype ; 2 males (SWUC-T-SP-03-03~04), Wuxi County, YNR, Lanying Village , 31°24′23′′N, 109°53′1′′E, elev. 1760 m, B. Tan leg.

Etymology. The specific name is derived from the type locality; noun in apposition.

Diagnosis. Male of Pseudopoda wuxi sp. n. resemble those of P. martensi Jäger, 2001 in having a similar embolic projection and dRTA ( Figs 22–23 , 27–29; Jäger, 2001, figs 39a–b, d) but can be distinguished by: 1) Retrolateral margin of embolus straight in ventral view in P. wuxi sp. n. ( Figs 22 , 28; round in P. martensi ); 2) vRTA with large triangular projection in P. wuxi sp. n. ( Figs 22 , 29; with no such projection in P. martensi ). Epigyne: See diagnosis of P. shuyue sp. n.

Description. Male holotype (Fig. 26) total length 9.06. Prosoma 4.19 long, 3.49 wide; Opisthosoma 4.45 long, 2.62 wide. Eye sizes and interdistances: AME 0.21, ALE 0.31, PME 0.28, PLE 0.35; AME–AME 0.17, AME–ALE 0.10, PME–PME 0.26, PME–PLE 0.32, ALE–PLE 0.28. MOA 0.76 long, anterior width 0.53, posterior width 0.78. Clypeus height 0.46. Chelicerae with 3 promarginal and 4 retromarginal teeth. Leg measurements: I 17.49 (5.05, 6.82, 3.97, 1.65); II 18.61 (5.43, 7.19, 4.33, 1.66); III 15.23 (4.63, 5.79, 3.39, 1.42); IV 16.98 (5.14, 5.83, 4.31, 1.70). Leg formula: 2143.

Palp ( Figs 22, 23 , 27–29): RTA with two branches, vRTA triangular with blunt end, dRTA longer than wide, horn-shaped, gradually narrowing towards the tip; tegulum ventrally grooved, retrolaterally strongly bulged, spermophor running submarginally along retrolateral margin of tegulum. Embolus flat, tip notched, apical end of embolus dorsally grooved, arising from 9-o’clock-position on tegulum, strongly curved with quadrangle embolic projection in ventral view; conductor membranous, sheet-like.

Coloration (Fig. 26): Carapace yellowish, with many dots and linear trident pattern, lateral margins with inconspicuous grey bands. Chelicerae, labium, gnathocoxae and sternum yellowish. Legs yellowish, with small spots and slightly larger spine patches. Dorsal opisthosoma yellowish, with distinct brown pattern, two pairs of sigilla; venter yellowish, with black patches.

Female (SWUC-T-SP-03-02, Fig. 30) total length 9.11. Prosoma 4.27 long, 3.70 wide; opisthosoma 4.63 long, 3.31 wide. Eye sizes and interdistances: AME 0.19, ALE 0.31, PME 0.24, PLE, 0.31; AME–AME 0.20, AME–ALE 0.08, PME–PME 0.25, PME–PLE 0.35, ALE–PLE 0.31. MOA 0.73 long, anterior width 0.52, posterior width 0.75. Clypeus height 0.32. Leg measurements: I 14.09 (4.02, 5.30, 3.39, 1.38); II 14.89 (4.46, 5.46, 3.58, 1.39); III 11.99 (3.85, 4.22, 2.43, 1.49); IV 14.12 (4.43, 4.57, 3.68, 1.44). Leg formula: 2143. Female opisthosoma color and pattern same as in male, except lighter in color.

Epigyne ( Figs 24, 25 , 31, 32): Epigynal field wider than long, median field extending posteriorly almost completely covering the copulatory openings; lateral lobes as wide as long, posteriorly narrowing, touching each other medially, posterior margins of lateral lobes inverted V-shaped; first windings distinct, somewhat wing-shaped, internal duct system sinuous, covered by the lateral lobes; fertilization ducts laterad in dorsal view.

Distribution. Known only from the type locality, Yintiaoling Natural Reserve, Chongqing, China.
