Sinopoda globosa Zhang, Zhang & Zhang, 2015, sp. nov.

Sinopoda globosa sp. nov.

(Figs 17–32)

Type material: Holotype: ♂, CHINA: Sichuan Province: Wolong Natural Reserve, 30°58′N, 103°15′E, 1200 m, near road, 19 July 2003, J.X. Zhang (MHBU, SP-SC-03-0025).

Paratype: 1♀, same data as holotype (MHBU, SP-SC-03-0026).

Etymology. The specific name is derived from the Latin word ‘globosus, -a, -um’, meaning ‘globose’, referring to the shape of spermathecae; adjective.

Diagnosis. The male and female of Sinopoda globosa sp. nov. are similar to those of S. triangula and S. longiducta sp. nov. in the long embolus, the triangular projection of subdistal embolus and the large globose spermathecae, and the diameter of the PP is almost twice the diameter of the internal duct system. The male differs from S. triangula by: conductor as long as tegulum; the median part of embolus wider than the proximal part (Figs 19–21, 26–29). For differences from S. longiducta sp. nov. see diagnosis of this species below. The female of the new species differs from S. triangula and S. longiducta sp. nov. by: glandular appendages short, extending posteriorly not in posterior half of internal duct system and converging apically; distance from glandular appendages to posterior part of spermatheca about 2.5 times of internal duct diameter (Figs 24–25, 30–32).

Dorsal opisthosoma gray-brown, heart patch and muscle impressions yellow, lateral field of opisthosoma with three pairs of black patches, posterior part with a black transversal band; venter gray-brown (Figs 17–18).

Palp (Figs 19–21, 26–29). Embolus long and slightly curving, arising from tegulum in a 7 to 8-o'clock-position (left palp in ventral view), embolus distally willow-leaf-shaped, and running parallel along embolic apophysis basally, slightly diverging in the apical part, basal part of embolus visible from ventral view, distal embolic apophysis hook-shaped; sperm duct slightly curved from ventral view; the base of RTA with a distinct brush of stiff setae; dRTA slender and finger-shaped, vRTA stout, with a pointed tip from ventral view; cymbium longer than tibia.

Female (Paratype): total length 14.40: prosoma 7.10 long, 6.20 wide; opisthosoma 7.30 long, 4.60 wide. Eye diameters and interdistances: AME 0.27, ALE 0.43, PME 0.34, PLE 0.44; AME–AME 0.30, AME–ALE 0.16, PME–PME 0.42, PME–PLE 0.60. MOA 0.96 long, anterior width 0.79, posterior width 1.07. Clypeus height 0.28. Leg measurements: I 22.40 (6.80, 1.80, 5.90, 5.80, 2.10), II 26.50 (7.60, 2.80, 7.10, 6.80, 2.20), III 19.30 (6.80, 1.80, 4.50, 4.30, 1.90), IV 20.30 (6.80, 1.90, 4.80, 4.70, 2.10).
