description: Pseudopoda emei sp. n. Figs 18-33 Type material. Holotype ♂ (SP–SC–03– 0050), from CHINA: Sichuan Province,Emei Mountain, Fuhu Temple (29°59'N, 103°48'E, 1800 m), 26.VII.2003, J.X. Zhang leg. (hand collecting), deposited in MHBU. Paratype: 1♂ (SP–SC–03– 0051), 2♀♀ (SP–SC–03–0052– 0053), same data as holotype; 1♀ (SP–SC–09– 24), from CHINA: Sichuan Province,Emei Mountain, native forest, 24.IX.2010, Y.W. Zhao leg. (hand collecting), deposited in MHBU. Etymology. The specific name refers to the type locality, the mountain Emei; noun in apposition. Diagnosis. Males of Pseudopoda emei sp. n. resemble those of Pseudopoda virgata (Fox, 1936), Pseudopoda kalinchoca Jäger, 2001 and Pseudopoda khimtensis Jäger, 2001 by the strongly flattened embolus and long embolic tip, but can be distinguished by the following combination of characters: basal and middle part of embolus very broad, but with slender tip, embolic tip filiform, curving slightly upward (Figs 20-21, 27-28), prolateral margin of embolus with a small embolic projection, embolic projection shorter than 1/3 length of embolic tip (Figs 21, 28). Females can be distinguished from those of other Pseudopoda species by: posterior epigynal field wider than anterior part; anterior margin of the lateral lobes distinctly curved and pointing anterior-laterally (Figs 25, 30); lateral lobes large, with distinct ridges in dorsal view, the length of lateral margin of lateral lobes almost equal to that of median margin in dorsal view (Figs 26, 31); posterior half of first winding of internal duct system covered by lateral lobes (Figs 26, 31). Description. Holotype (SP–SC–03– 0050): total length 15.39; prosoma 7.21 long, 6.02 wide; opisthosoma 8.23 long, 4.82 wide. Prosoma with some setae. Fovea long, longitudinal. Coloration: Dorsal shield of prosoma yellow. Radial furrows and fovea dark brown. Chelicerae brown. Labium, gnathocoxae and sternum yellowish brown. Sternum with dark spots and setae. Legs yellow, with dark dots randomly distributed, and especially on the setae and spine bases of coxa and femur. Dorsal opisthosoma yellow, anterior part with black patches, cardiac pattern and muscle impressions dark brown, followed by three black transverse lines and two longitudinal black patches; lateral part with some smaller irregular patches (Fig. 18); venter yellow, with two black lateral lines and a black patch before spinnerets (Fig. 19). Both eye rows slightly recurved. Eye diameters and interdistances: AME 0.34, ALE 0.49, PME 0.36, PLE 0.47; AME–AME 0.21, AME–ALE 0.08, PME–PME 0.43, PME–PLE 0.52. MOA 1.17 long, anterior width 0.83, posterior width 1.16. Clypeus height 0.32. Chelicerae with three promarginal and four retromarginal teeth, and with thirteen denticles between them. Leg measurements: I 36.66 (9.51, 3.20, 10.22, 10.52, 3.21), II 36.85 (9.53, 3.23, 10.28, 10.56, 3.25), III 36.40 (9.43, 3.16, 10.19, 10.42, 3.20), IV 36.49 (9.48, 3.17, 10.22, 10.42, 3.20). Leg formula: 2143. Leg spination: palps 131, 101, 2121; femur I–III 323, IV 331; patella I–IV 101; tibia I–II 2226, III–IV 2126; metatarsus I–II 2024, III 2026, IV 3036. Male palp. Embolus long, arising from 8 o'clock-position on tegulum (Figs 20-21, 27-28), basal and middle part of embolus very broad, but with long and filiform tip, pointing ventro-prolaterally (Figs 20-21, 27-28); EP small (Figs 21, 28); sperm duct running submarginally along retrolateral margin of tegulum in ventral view (Figs 21-22, 28-29); RTA long, with broad base, arising medially to basally from tibia, dorsal branch narrow and curved, ventral branch short, wide, and as a small hump in retrolateral view (Figs 21-22, 28-29). Females. Paratype (SP–SC–03– 0052): total length 13.22; prosoma 6.41 long, 5.52 wide; opisthosoma 6.82 long, 4.89 wide. Coloration: Dorsal shield of prosoma reddish brown. Legs brown, with dark dots randomly distributed, and especially on the setae and spine bases of coxa and femur. Dorsal opisthosoma dark brown, cardiac pattern and muscle impressions black, followed by a transverse line composed of white hairs and two longitudinal black patches. Coloration pattern darker than male (Figs 23-24). Eye diameters and interdistances: AME 0.29, ALE 0.40, PME 0.33, PLE 0.39; AME–AME 0.29, AME–ALE 0.14, PME–PME 0.57, PME–PLE 0.47. MOA 1.17 long, anterior width 0.81, posterior width 1.14. Clypeus height 0.32. Leg measurements: I 22.27 (7.02, 2.83, 5.17, 5.17, 2.08), II 22.38 (7.06, 2.83, 5.18, 5.17, 2.14), III 21.71 (6.65, 2.81, 5.12, 5.15, 1.98), IV 21.89 (6.68, 2.83, 5.15, 5.19, 2.04). Leg formula: 2143. Leg spination: palps 131, 101, 2121, 2112; femur I–III 323, IV 321; patella I–IV 101; tibia I–IV 2126; metatarsus I–II 2024, III 2026, IV 3036. Epigyne. Epigynal field wider than long, anterior margin without longitudinal bands (Figs 25, 30); LLs width equal to length, touching each other along the median line, anterior margin of LLs distinctly curved and pointing anterior-laterally, posterior margins of LLs rounded, and with distinct posterior incisions (Figs 25, 30), LLs large, with distinct ridges in dorsal view (Figs 26, 31); internal duct system visible through cuticle as almost rectangular dark patches (Figs 25, 30); posterior end of first winding of internal duct system covered by LLs (Figs 26, 31). Variation. Male total body length from 15.32-15.39, and female from 13.22-14.21. Femur length of male: I from 9.48-9.51, II from 9.51-9.53, III from 9.42-9.43, IV from 9.46-9.48.

Males of Pseudopoda emei sp. n. could be included in the Pseudopoda martensi -group by: embolus sickle-shaped, strongly flattened, and arising in a prolateral position on the tegulum, first bending in a retrolateral direction and then running in a distal direction; small embolic projection present.
