Type material. Holotype male: CHINA: Hunan Province : Chenzhou City, Yanling County, Shenlonggu Forest Park , 26.52°N, 114.01°E, 1350 m, native forest, 24 June 2017, Y. Zhong & Y. Zhu leg. (CBEE). Paratypes: 3 females, with same data as holotype ( CBEE) .

Additional material examined. CHINA: Jiangxi Province : 1 male, 3 females, Jinggangshan City, Ciping Town, Jinggangshan Revolutionary Martyrs Cemetery , 26.35°N, 114.10°E, 867 m, native forest, 13 October 2013, Yang Zhong leg. (CBEE).

Etymology. The specific name is taken from the type locality, Yanling County; adjective.

Diagnosis. This new species resembles S. tumefacta sp. nov. ( Figs 53 A–E, 54A–D, 55A–B) in having a thin embolus with a reduced embolic apophysis and lateral lobes fused, with almost horizontal margins anteriorly, but can be separated by: 1. Male palp with dRTA narrow and dorsally digitiform (wide, bulging in S. tumefacta ); 2. Female vulva with glandular appendages short (long in S. tumefacta ), posterior parts of spermathecae distinctly swollen (slightly swollen in S. tumefacta ).

Description. Male (holotype): Measurements: PL 4.5, PW 4.3; AW 2.2; OL 4.6, OW 3.2.

Measurements of palp and legs: Palp 7.2 (2.3, 1.1, 1.4, –, 2.4); I 22.2 (5.9, 1.9, 6.1, 6.3, 2.0); II 25.7 (6.8, 2.0, 7.3, 7.4, 2.2); III 18.7 (5.7, 1.8, 4.9, 4.8, 1.5); IV 21.2 (6.1, 1.8, 5.4, 6.1, 1.8). Leg formula: II-I-IV-III. Cheliceral furrow with 3 anterior, 4 posterior teeth and ca. 28 denticles.

Palp as in diagnosis. Cymbium distinctly longer than tibia. Embolus arising from tegulum at 6-o’clock-position. Spermophor curved in ventral view. Tegulum covering median part of embolus almost over its entire length. RTA arising distally to medially from tibia ( Figs 59 A–C, 60A–D).

Colouration in ethanol. Dorsal prosoma yellowish-brown, lateral margins dark, with dark and light submarginal transversal bands posteriorly. Labium and gnathocoxae pale yellowish-brown, the former with distal parts lighter. Sternum yellowish-brown. Chelicerae deep reddish-brown. Legs yellowish-brown with dark spots. Dorsal opisthosoma reddish-brown, covered by brown hairs, with light narrow lanceolate heart patch, with three pairs of

dark patches laterally and one dark transversal band above spinnerets. Ventral opisthosoma yellowish-brown with irregular pattern, with dark part in front of spinnerets ( Figs 60 E–F).

Female: Measurements: PL 5.2, PW 4.6; AW 2.9; OL 5.3, OW 3.5. Eyes:AME 0.27, ALE 0.39, PME 0.28, PLE 0.40, AME–AME 0.23, AME–ALE 0.11, PME–PME 0.33, PME–PLE 0.70, AME–PME 0.42, ALE–PLE 0.48, CH AME 0.34, CH ALE 0.37. Spination: Palp: 131, 101, 2121, 1014; Fe: I–III 323, IV 321; Pa: I–IV 001; Ti: I–III 2026, IV 2126; Mt: I–II 0 0 0 4, III 2026, IV 3036. Measurements of palp and legs: Palp 5.5 (1.7, 0.6, 1.3, –, 1.9); I 15.6 (4.4, 1.5, 4.5, 3.8, 1.4); II 17.5 (5.4, 1.7, 4.9, 4.2, 1.3); III 14.2 (4.3, 1.4, 3.9, 3.3, 1.3); IV 16.3 (4.6, 1.3, 4.4, 4.4, 1.6). Leg formula: II-IV-I-III. Cheliceral furrow with 3 anterior, 4 posterior teeth and ca. 32 denticles.

Copulatory organ as in diagnosis. Epigynal field wider than long, with narrow anterior bands. Lateral lobes fused, with broadly triangular median incision. Internal ducts stout, running two thirds parallel along the median line. Glandular appendages much narrower than other parts of the duct system, postero-laterad. Fertilization ducts arising posterioly ( Figs 59 D–E, 61A–B).

Colouration in ethanol. As in males, but prosoma dorsally with much more dark setae and dorsal opisthosoma dark brown ( Figs 61 C–D).

Distribution. China (Hunan; Jiangxi) ( Fig. 62 ).
