description: Pseudopoda gibberosa sp. nov.
(Figs 1–12)
Type material: Holotype: ♂, Pianma town (26°10′N, 98°38′E), native forest, 2500 m, Lushui County, Yunnan Province, China, 3 March 2011, Z.X. Li (MHBU, SP-GLGS-11-3701).
Paratypes: 2♀♀, same data as holotype (1 female in MHBU, SP-GLGS-11-3702, 1 female in SWUC, SP- GLGS-11-3703); 1♂, Yaojiaping (25°58′N, 98°42′E), primary forest, 2740 m, Lushui County, Yunnan Province, China, 28 November 2011, L.Y. Wang (SWUC, SP-GLGS-11-1102).
Etymology. The specific name is derived from the Latin word ‘gibberosus, -a, -um’, meaning ‘humpbacked’, referring to the shape of the EP; adjective.
Diagnosis. Males of the new species can be distinguished from those of other Pseudopoda species (except P. digitata Jäger & Vedel, 2007, P. daliensis Jäger & Vedel, 2007 and P. contentio Jäger & Vedel, 2007) by the following combination of characters (Figs 2–4, 8–10): embolus broad, its tip sickle-shaped; dorsal part of RTA extremely thin and distinctly curved, ventral RTA appearing as a small hump. The males differ from P. digitata by a smaller EP; from P. daliensis by the shape of the dorsal RTA; from P. contentio by the shape of the ventral RTA. Females can be distinguished from those of other Pseudopoda species (except P. digitata and P. obtusa) by: ME shaped as an inverted trapeziform; anterior rims of the LLs distinctly curved and pointing laterally. The females differ from P. obtusa and P. digitata by the internal duct system appearing as rectangular dark patches in ventral view (Figs 6–7, 11–12).
Description. Male: Total length 5.90–5.96. Holotype: total length 5.90; prosoma 2.81 long, 1.76 wide; opisthosoma 3.14 long, 1.62 wide. Dorsal shield of prosoma yellow, wide lateral bands dark brown. Cervical grooves and radial furrows obvious. Fovea long, longitudinal, dark brown. Ocular area brown. Each eye surrounded by black patch. AER slightly recurved, PER almost straight. Eyes diameters and interdistances: AME 0.13, ALE 0.26, PME 0.20, PLE 0.23; AME–AME 0.13, AME–ALE 0.04, PME–PME 0.23, PME–PLE 0.26. MOA 0.55 long, anterior width 0.39, posterior width 0.62. Clypeus height 0.19. Chelicerae yellow brown, with 3 promarginal teeth and 4 retromarginal teeth, and some denticles between them. Labium, gnathocoxae and sternum yellow brown. Sternum with dark setae. Legs yellow, femora with dark spots. Leg measurements: I 12.18 (3.12, 1.23, 3.12, 2.91, 1.80), II 12.60 (3.23, 1.34, 3.25, 2.95, 1.83), III 10.93 (2.56, 0.95, 2.80, 2.85, 1.77), IV 11.97 (2.99, 1.20, 3.10, 2.88, 1.80). Leg formula: 2143. Leg spination: palp 131, 101, 2121; femur I–II 323, III 322, IV 331; patella I 0 0 1, II–III 000; tibia I–IV 2026; metatarsus I–II 1014, III 2026, IV 3036. Dorsal opisthosoma reddish brown, lateral part of anterior half bright (Fig. 1); venter yellow, with a big black patch in front of spinnerets.
Male palp as in diagnosis (Figs 2–4, 8–10). Embolus flat, middle part broadened, arising from 10 to 10.30- o’clock-position on tegulum, its tip pointing dorso-prolaterally; EP apearing as a small hump; sperm duct running submarginally on retrolateral tegulum; RTA with broad base, arising basally from tibia.
Female: Total length 7.12–7.21. One paratype: total length 7.21; prosoma 3.21 long, 2.82 wide; opisthosoma 4.02 long, 2.23 wide.

Clypeus height 0.23. Labium, gnathocoxae and sternum brown. Legs yellow brown, patella, tibia and metatarsus with circular patches. Leg measurements: I 10.81 (3.22, 1.03, 2.41, 2.52, 1.63), II 11.24 (3.26, 1.13, 2.51, 2.63, 1.71), III 10.21 (2.95, 0.97, 2.32, 2.45, 1.52), IV 10.67 (3.18, 1.05, 2.35, 2.49, 1.60). Leg formula: 2143. Leg spination: palp 131, 101, 2121, 2112; femur I–II 323, III 322, IV 331; patella I–IV 000; tibia I–IV 2026; metatarsus I–II 1014, III 2026, IV 3036.
