Pseudopoda gibberosa View in CoL sp. nov.

( Figs 1–12 View FIGURES 1 – 7 View FIGURES 8 – 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 View FIGURES 1 – 7 , 8–10 View FIGURES 8 – 12 ): 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 View FIGURES 1 – 7 , 11–12 View FIGURES 8 – 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 View FIGURES 1 – 7 ); venter yellow, with a big black patch in front of spinnerets.

Male palp as in diagnosis ( Figs 2–4 View FIGURES 1 – 7 , 8–10 View FIGURES 8 – 12 ). 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. Eyes diameters and interdistances: AME 0.13, ALE 0.29, PME 0.21, PLE 0.26; AME–AME 0.18, AME–ALE 0.05, PME–PME 0.23, PME–PLE 0.33. MOA 0.60 long, anterior width 0.44, posterior width 0.61. 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. Posterior half of dorsal opisthosoma with a transverse white line. Otherwise, the shape, color and markings of body as in male ( Fig. 5 View FIGURES 1 – 7 ).

Epigynal field wider than long, without anterior bands; the width of LLs equal to length, touching each other medially, posterior margins of LLs with distinct median indentation; posterior part of first windings of internal duct system covered by LLs.
