Zhang, Bao-Shi, Zhang, Feng & Zhang, Zhi-Sheng, 2013, Four new species of the genus Pseudopoda Jäger, 2000 (Araneae, Sparassidae) from Yunnan Province, China, Zootaxa 3702 (3), pp. 273-287 : 279

Pseudopoda semiannulata sp. nov.

( Figs 13–24 )

Type material: Holotype: ♂, Jietou Town 25°18′N, 98°21′E), native forest, 2000 m, Tengchong County, Yunnan Province, China, 23 February 2011, Z.X. Li ( MHBU, SP-GLGS-11-2101).

Paratypes: 8♂♂, 4♀♀, same data as holotype (1 female in MHBU, SP-GLGS-11-2102, 8 males and 3 females in SWUC, SP-GLGS-11- 2103 –2113).

Etymology. The specific name is derived from the Latin word ‘semi-’, meaning ‘half’, and ‘annulatus, -a, - um’, meaning ‘annular, or ring shaped’, referring to the nearly semicircular appearance of the EP; adjective.

Diagnosis. Males of the new species can be distinguished from those of other Pseudopoda species (except P. daliensis Jäger & Vedel, 2007 ) by the falciform embolus, nearly semicircular EP, and wide proximal part of the embolus. The males of the new species differ from P. daliensis by the semicircular EP, and the longer and digitiform dorsal RTA ( Figs 14–16 , 20–22 ). Females can be distinguished from those of other Pseudopoda species (except P. obtusa Jäger & Vedel, 2007 ) by the following combination of characters: ME shaped as an inverted trapeziform, anterior margins of LLs distinctly bent, and pointing 45° anteriolaterally, fertilisation ducts forming a wide rectangle. The females of the new species differ from P. obtusa by internal ducts appearing as longitudinal dark patches from the ventral view ( Figs 18–19 , 23–24 ).

Description. Male: Total length 6.12–6.20. Holotype: total length 6.20; prosoma 3.11 long, 2.61 wide; opisthosoma 3.11 long, 1.94 wide. Dorsal shield of prosoma yellow, lateral bands reddish brown. Cervical grooves and radial furrows obvious. Fovea long, longitudinal, dark brown. Ocular area reddish brown, with few long setae. Each eye surrounded by black patch. AER slight recurved, PER almost straight. Eyes diameters and interdistances: AME 0.16, ALE 0.30, PME 0.25, PLE 0.26; AME–AME 0.16, AME–ALE 0.06, PME–PME 0.23, PME–PLE 0.35. MOA 0.70 long, anterior 0.42 wide, posterior 0.68 wide. Clypeus height 0.22. Chelicerae yellow, with 3 promarginal teeth and 4 retromarginal teeth, and some denticles between them. Labium, gnathocoxae and sternum yellow. Sternum with dark brown setae. Legs brown and spinose, femora with dark spots. Leg measurements: I 11.08 (2.93, 1.26, 3.06, 2.70, 1.13), II 12.47 (3.60, 1.35, 3.24, 3.06, 1.22), III 10.09 (2.88, 1.13, 2.52, 2.52, 1.04), IV 11.84 (3.33, 1.17, 2.93, 3.24, 1.17). Leg formula: 2413. Leg spination: palp 131, 101, 2121; femur I–III 323, IV 331; patella I–IV 001; tibia I–IV 2026; metatarsus I–II 1014, III 2026, IV 3036. Dorsal opisthosoma with dark heart patch and, anterior part with bright lateral parts; posterior half dark, with a transverse white line; venter bright tan colored, with small reddish brown patches ( Fig. 13 ).

Palp as in diagnosis ( Figs 14–16 , 20–22 ). Embolus flat, arising from 9-o'clock-position on the tegulum, running broadly as an S-shaped curve, its tip pointing prolaterally, EP longer and thicker than tip of embolus; sperm duct almost straight, running submarginally along retrolateral tegulum from the ventral view; RTA arising medially from the palpal tibia, with ventral bulge, straight tip of dorsal RTA thin.

Female: Total length 6.16–6.28. One paratype: total length 6.28; prosoma 3.13 long, 2.61 wide; opisthosoma 3.20 long, 1.99 wide. Eyes diameters and interdistances: AME 0.16, ALE 0.31, PME 0.23, PLE 0.29; AME–AME 0.17, AME–ALE 0.07, PME–PME 0.27, PME–PLE 0.35. MOA 0.69 long, anterior 0.42 wide, posterior 0.68 wide. Clypeus height 0.23. Leg measurements: I 9.04 (2.52, 1.26, 2.34, 2.11, 0.81), II 10.07 (2.93, 1.13, 2.43, 2.47, 1.07), III 8.45 (2.39, 0.99, 2.12, 2.07, 0.81), IV 10.00 (2.88, 1.35, 2.48, 2.30, 0.99). Leg formula: 2413. Leg spination: palp 131, 101, 2121, 2112; femur I–II 323, III 322, IV 331; patella I–IV 001; tibia I–IV 2026; metatarsus I–II 1014, III 2026, IV 3036. The shape, color and markings of body as in male ( Fig. 17 ).

Epigyne as in diagnosis ( Figs 18–19 , 23–24 ). Ventral view with epigynal field wider than long, anterior margin rather indistinct; anterior bands short; LLs wider at the base and shaped as truncated field hockey sticks, touching each other at the median line; posterior margins of LLs with distinct median indentation; posterior part of first winding of internal duct system covered by LLs.

Distribution. China (Yunnan).
