Type material. Holotype female: CHINA: Hunan Province: Huaihua City, Mayang County, Pantian Village, 27.63°N, 109.64°E, 558 m, near road, 24 April 2016, Y. Zhong, Y. Zhu & H. Zhang leg. (CBEE). Paratype: 1 female, with same data as holotype (CBEE).
Etymology. The specific epithet is a Latin participle, dehiscens, meaning “dehiscent” referring to the dehiscent anterior part of internal ducts.
Diagnosis. This new species resembles S. erromena sp. nov. (Figs 22 A–B, 23A–B) in having similarly shaped epigynal structures including a small triangular posteriad projection covering the anterior part of the lobal septum as well as a similar configuration of the internal duct system especially the anterior part with the way the glandular appendages are bent, but can be separated by: 1. Vulva with glandular appendages as wide as posterior parts of spermathecae (distinctly wider in S. erromena sp. nov.); 2. Vulva with posterior parts of spermathecae distinctly swollen (slightly swollen in S. erromena sp. nov.) (Figs 20 A–B, 21A–B).
Description. Female (holotype): Measurements: PL 6.0, PW 5.3; AW 3.2; OL 6.6, OW 4.2. Eyes: AME 0.21, ALE 0.39, PME 0.26, PLE 0.39, AME–AME 0.25, AME–ALE 0.12, PME–PME 0.38, PME–PLE 0.48, AME–PME 0.41, ALE–PLE 0.40, CH AME 0.27, CH ALE 0.40. Spination: Palp: 131, 101, 2121, 1014; Fe: I–III 323, IV 331; Pa: I–IV 001; Ti: I–IV 2026; Mt: I–II 0 0 0 4, III 1014, IV 3036. Measurements of palp and legs: Palp 7.9 (2.6, 0.9, 1.7, –, 2.7); I 21.0 (6.0, 2.4, 5.6, 5.2, 1.8); II 22.2 (6.6, 2.5, 6.1, 5.4, 1.6); III 18.4 (5.6, 1.9, 5.0, 4.3, 1.6); IV 20.5 (6.0, 1.8, 5.5, 5.4, 1.8). Leg formula: II-IV-I-III. Cheliceral furrow with 3 anterior, 4 posterior teeth and ca. 22 denticles.
Copulatory organ as in diagnosis. Epigynal field wider than long, with short anterior bands and one slit sensillum on each side of the epigynal field. Lateral lobes fused. Lobal septum wide, forming a triangle. Fertilization ducts arising posterio-laterally. Membranous sac between fertilization ducts almost rectangular (Figs 20 A–B, 21A–B).
Colouration in ethanol. Dorsal prosoma yellow-brown, posterior part covered by dark hairs. Fovea reddishbrown and radial furrows distinctly marked. Labium and gnathocoxae yellowish-brown, both with distal parts lighter. Sternum yellowish-brown. Chelicerae deep reddish-brown. Legs yellowish-brown with dark spots. Dorsal opisthosoma reddish-brown, covered by grey hairs, heart patch and muscle sigilla yellow, two thirds of opisthosoma with three pairs of black patches. Ventral opisthosoma yellow-brown (Figs 21 C–D).
Distribution. China (Hunan) (Fig. 62).
