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 : 282-285

Pseudopoda triangula sp. nov.

( Figs 37–48 )

Type material: Holotype: ♂, Jietou Town, native forest, 2000 m, Tengchong County, Yunnan Province, China, 25 February 2011, L.Y. Wang ( MHBU, SP-GLGS-11-2401).

Paratypes: 17 ♂♂, 18♀♀, same data as holotype (1 female in MHBU, SP-GLGS-11-2402, 17 males and 17 females in SWUC, SP-GLGS-11- 2403 –2436).

Etymology. The specific name is derived from the Latin word ‘triangulus, -a, -um’, meaning ‘triangular’, referring to the triangular EP; adjective.

Diagnosis. Males of the new species can be distinguished from those of other Pseudopoda species (except P. contraria Jäger & Vedel, 2007 ) by the huge EP and flagelliform embolus. The new species differs from P.

contraria by the shorter RTA, the longer embolus and the shape of embolic apophysis ( Figs 38–40 , 44–46 ). Females can be distinguished from those of other Pseudopoda species by: LLs distinctly separate from each other ( Figs 42–43 , 47–48 ).

Description. Male: Total length 4.70–4.75. Holotype: total length 4.75; prosoma 2.41 long, 2.16 wide; opisthosoma 2.34 long, 1.94 wide. Dorsal shield of prosoma yellow, wide lateral bands reddish brown. Cervical grooves and radial furrows obvious. Fovea long, longitudinal, reddish brown. Ocular area reddish brown. Each eye surrounded by black patch. AER slight recurved, PER almost straight. Eyes diameters and interdistances: AME 0.13, ALE 0.30, PME 0.21, PLE 0.26; AME–AME 0.10, AME–ALE 0.04, PME–PME 0.21, PME–PLE 0.36. MOA 0.60 long, anterior 0.34 wide, posterior 0.57 wide. Clypeus height 0.18. 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 yellow, femora with dark spots. Leg measurements: I 7.97 (2.25, 0.99, 1.98, 1.94, 0.81), II 8.87 (2.52, 1.04, 2.25, 2.25, 0.81), III 7.62 (2.25, 0.95, 1.80, 1.85, 0.77), IV 8.79 (2.57, 0.90, 1.98, 2.48, 0.86). Leg formula: 2413. Leg spination: palp 131, 101, 2121; femur I–II 323, III 322, IV 331; patella I–IV 001; tibia I–III 2026, IV 2126; metatarsus I–II 1014, III 2026, IV 3036. Dorsal opisthosoma reddish brown, bright lateral parts in anterior half; posterior half with a transverse white line ( Fig. 37 ); venter bright, with a wide reddish brown belt lengthwise centrally.

Palp as in diagnosis ( Figs 38–40 , 44–46 ). Embolus flat, arising from 7-o'clock-position on tegulum, strongly broadened in its middle part; thin distal part of embolus pointing prolaterally; EP triangular and very large, pointing prolaterally; sperm duct running submarginally on retrolateral tegulum; RTA short, arising medially from tibia.

Female: Total length 6.32–7.00. One paratype: total length 7.04; prosoma 2.90 long, 2.31 wide; opisthosoma 4.12 long, 2.93 wide. Eyes diameters and interdistances: AME 0.10, ALE 0.31, PME 0.20, PLE 0.27; AME–AME 0.14, AME–ALE 0.05, PME–PME 0.22, PME–PLE 0.31. MOA 0.61 long, anterior 0.36 wide, posterior 0.58 wide. Clypeus height 0.23. Leg measurements: I 8.18 (2.12, 1.11, 2.04, 1.80, 1.11), II 9.36 (2.72, 1.31, 2.32, 1.90, 1.11), III 7.14 (1.82, 0.90, 1.80, 1.71, 0.91), IV 8.57 (2.33, 1.21, 2.01, 1.80, 1.22). Leg formula: 2413. Leg spination: palp 131, 101, 2121, 2112; femur I 322, II 323, III 322, IV 321; patella I 0 0 0, II–IV 001; tibia I–III 2026, IV 2126; metatarsus I–II 1014, III 2026, IV 3036. The shape, color and markings of body as in male ( Fig. 41 ).

Epigyne as in diagnosis ( Figs 42–43 , 47–48 ). Epigynal field slightly wider than long, anterior margin indistinct, without anterior bands; LLs elongated and oval, anterior narrower than base; in dorsal view, loops of internal ducts system extending laterally and beyond first windings.

Distribution. China (Yunnan).
