Figures 1 , 2 , 9

Type material. Holotype: female (ASM-JGSU) from Longtan, Xiaojing village, Ciping Town, Jinggangshan County Level City, Jiangxi Province, China (26.599°N, 114.140°E, alt. 838 m), 31.V.2014, K. Liu, X. Huang, Z. Chen, Y. Tang, Z. Meng & Z. Wang. Paratype: 1 female (ASM-JGSU), same data as holotype.

Etymology. Species named after the type locality (adjective).

Diagnosis. Females of the new species resemble those of S. kosi Logunov & Hereward, 2006 , S. martensi Bohdanowicz, 1987 and S. zonatus Peng & Li, 2008 in having the developed C-shaped sclerotized loops of the copulatory duct, but can be clearly distinguished ( Figs 1C–D , 2 ) by the strongly enlarged median-posterior part of epigynal loop (see Logunov & Hereward 2006: figs 32−33), the shorter copulatory duct (see Logunov & Hereward 2006: figs 32−33) and the glandular duct ( S. zonatus without this structure, see Peng et al. 2008: figs 23–25).

Description. Female ( Figs 1 , 2 ). Total length 4.10, CL 1.70, CW 1.07, AL 2.30, AW 1.19. EL 0.91; AERW 0.98, AMEW 0.64, PERW 1.03, PMEW 0.93. Carapace reddish-brown ( Fig. 1A ). Eye field square ( Fig. 1A ), covered with short yellow hairs; anterior eye row with abundant yellowish-brown hairs, and a row of light, medially bent setae. Fovea oval, hollowed ( Fig. 1A ). Chelicerae yellowish-brown ( Fig. 1B ). Endites yellowishbrown ( Fig. 1B ), longer than wide, with short, scattered, brown hairs. Labium light yellow ( Fig. 1B ), with a few strong setae on the anterior margin. Sternum yellow, with abundant hairs on the surface. Measurements of legs: I 3.00 [0.95, 0.61, 0.80, 0.36, 0.28]; II 2.15 [0.68, 0.34, 0.48, 0.41, 0.24]; III 2.24 [0.68, 0.27, 0.53, 0.49, 0.27]; IV 3.25 [0.92, 0.43, 0.82, 0.76, 0.32]. Leg formula: IV, I, III, II. Femur I width 0.38; femur II width 0.21. Leg spination: I: Tibia p v 2-2 -1, r v 2-2 -1; Metatarsus p v 1 -0-1, r v 1 -0-1. Abdomen oval ( Figs 1A, B ), dorsum yellowish-gray, without obvious patches on anterior part, with 6 lighter herringbone strips in posterior part.

Spinnerets yellowish-brown ( Fig. 1B ), with abundant brown hairs. Epigyne ( Figs 1C–D , 2 ) apple-like, copulatory opening bilaterally located; copulatory duct extends anteriorly, forms a sclerotized C-shaped loop medially, distally slender with a short glandular duct; spermatheca oval, obvious, connected with the rather short fertilization duct.

Male: Unknown.

Distribution. Known only from Jiangxi province, China ( Fig. 9 ).
