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 : 279-282

Pseudopoda breviducta sp. nov.

( Figs 25–36 )

Type material: Holotype: ♂, Dawei Mountains (23°13′N, 103°45′E), evergreen broad-leaf forest, 1300 m, Pingbian County, Yunnan Province, China, 10 May 2011, Z.X. Li ( MHBU, SP-PB-11-5801).

Paratype: 1♀, same data as holotype ( MHBU, SP-PB-11-5802).

Etymology. The specific name is derived from the Latin word ‘brevi’, meaning ‘short’ and the Latin word ‘ductus, -a, -um’, meaning ‘tubular’, referring to the short tubular distal tip of the embolus; adjective.

Diagnosis. The male of the new species can be distinguished from that of other Pseudopoda species by the following combination of characters ( Figs 26–28 , 32–34 ): embolus broad and upright, almost triangular with a short and thin embolic tip. The female can be distinguished from that of other Pseudopoda species [except P. zhangmuensis (Hu & Li, 1987) and P. lutea (Thorell, 1895) ] by the nearly circular ME, interior margins of the LLs distinctly curved and pointing medially. The female of the new species differs from P. zhangmuensis by the following characters: ME of this new species width equal to its length, anterior margin of epigynal field recurved; ME of P. zhangmuensis wider than long, anterior margin of epigynal field procurved. The new species differs from P. lutea by the smooth posterior margins of the LLs and lateral copulatory openings ( Figs 30–31 , 35–36 ).

Description. Male: Holotype: total length 9.31; prosoma 4.11 long, 3.02 wide; opisthosoma 5.19 long, 2.13 wide. Dorsal shield of prosoma yellow, wide lateral patches yellow brown. Cervical grooves and radial furrows obvious. Fovea long, longitudinal, brown. Ocular area yellow brown. Each eye surrounded by black patch. AER slight recurved, PER almost straight. Eyes diameters and interdistances: AME 0.21, ALE 0.26, PME 0.18, PLE 0.23; AME–AME 0.18, AME–ALE 0.04, PME–PME 0.26, PME–PLE 0.30. MOA 0.61 long, anterior width 0.49, posterior width 0.57. Clypeus height 0.23. Chelicerae yellow, with 3 promarginal teeth and 4 retromarginal teeth, and some denticles between them. Labium, gnathocoxae and sternum yellow. Sternum with dark setae. Legs yellow, femora with dark spots. Leg measurements: I 22.35 (6.21, 1.80, 6.12, 6.12, 2.10), II 22.61 (6.23, 1.84, 6.18, 6.20, 2.16), III 21.50 (6.13, 1.66, 5.89, 5.85, 1.97), IV 22.15 (6.18, 1.73, 6.02, 6.12, 2.10). Leg formula: 2143. Leg spination: palp 131, 101, 2121; femur I–III 323, IV 331; patella I–II 101, III–IV 001; tibia I–II 2226, III–IV 2126; metatarsus I–II 2024, III 2026, IV 3036. Dorsal opisthosoma yellow, heart patch grey brown, with a reddish brown retiform patch in posterior half and some smaller irregular patches laterally ( Fig. 25 ); venter yellow, with small black patches.

Palp as in diagnosis ( Figs 26–28 , 32–34 ). Tegulum in the ventral view resembles a small bean sprout with radix upwards; embolus arising from 9-o’clock-position on tegulum, its tip very short, middle part with a distinctive outward projection; sperm duct almost straight, running close to retrolateral margin of tegulum; RTA with broad base, arising medially on the tibia, tip of dorsal RTA thin and almost straight, ventral RTA short and thick, with pointed tip.

Female: Paratype: total length 9.54; prosoma 4.21 long, 3.52 wide; opisthosoma 5.32 long, 3.12 wide. Eyes diameters and interdistances: AME 0.17, ALE 0.29, PME 0.20, PLE 0.33; AME–AME 0.20, AME–ALE 0.13, PME–PME 0.34, PME–PLE 0.42. MOA 0.75 long, anterior 0.52 wide, posterior 0.78 wide. Clypeus height 0.26. Leg measurements: I 13.60 (4.22, 1.83, 2.91, 3.01, 1.63), II 14.17 (4.26, 1.83, 2.98, 3.03, 1.71), III 12.91 (3.95, 1.97, 2.62, 2.85, 1.52), IV 13.37 (4.18, 1.85, 2.75, 2.99, 1.60). Leg formula: 2143. Leg spination: palp 131, 101, 2121, 2112; femur I–II 323, III 322, IV 331; patella I–IV 001; tibia I 2026, II–IV 2126; metatarsus I–II 2024, III 2026, IV 3036. Dorsal opisthosoma yellow, heart patch reddish brown, sub-lanceolate, a transversal patch followed a by a light line in posterior half and some smaller irregular patches laterally, the other color and markings of body darker than in male ( Fig. 29 ).

Epigyne as in diagnosis ( Figs 30–31 , 35–36 ). Epigynal field without anterior bands; LLs wider than long, touching each other medially; posterior margins of LLs curved, and with indistinct median indentation; internal duct system appearing as transverse oval dark patches from the ventral view.

Distribution. China (Yunnan).
