Material examined. Holotype ♂ (IZCAS), China, Yunnan Province, Wenshan Zhuang and Miao Autonomous Prefecture, Gejiu City, Manhao Town, Lvshuihe Tropical Forest Reserve (23º1.535′N, 103º24.063′E), elev. 477 m, 19.V.2015, leg. Z. Chen & Y. Li. Paratypes 2♂ 3♀ (IZCAS), same data as holotype.
Etymology. The specific name is derived from the type locality; noun.
Diagnosis. The new species is similar to S. bicornea Tong & Li, 2007, but males can be distinguished by the irregular spherical palpal bulb (Figs 33A–B) and females by the long afferent spermathecae (Figs 34B, D). S. bicornea has a spherical palpal bulb and short afferent spermathecae that do not extend to the upper sides of the abdomen (Tong & Li, 2007: fig. 7).
Description. Male. Total length 1.08; carapace length 0.50; carapace width 0.43; abdomen length 0.54; abdomen width 0.38. Prosoma: carapace pyriform, narrowing gradually anteriorly; light yellow, suffused with purplish pattern (Fig. 34C); pars cephalica flat; fovea not visible. Sternum light yellow, suffused with purplish color, longer than wide. Endites light yellow suffused with purplish tinge; with serrula; labium light yellow suffused with purplish tinge. Clypeus nearly vertical; short. Chelicerae light yellow, lateral margin strongly excavated, with a very small horn-like apophysis; promargin with a series of six teeth reaching the lamina; retromargin with two very small denticles (Figs 56E–F). Eyes: six contiguous eyes surrounded by black pigmentation; PME smallest, PLE largest (Fig. 34C). Opisthosoma oval; purplish. Legs light yellow; leg formula 4123; leg lengths I 1.95 (0.55, 0.16, 0.61, 0.36, 0.27); II 1.77 (0.51, 0.16, 0.50, 0.33, 0.27); III 1.59 (0.45, 0.14, 0.42, 0.33, 0.25); IV 2.15 (0.62, 0.15, 0.62, 0.45, 0.31). Genitalia (Fig. 33). Palpal femur long; palpal tibia about 1.3 times as long as cymbium (Figs 33A–B). Cymbium conical, with large prolateral extension basally. Bulb shaped like an irregular sphere. Embolus short, dark and basally with belt-like associated sclerites; sperm duct initially wide, abruptly narrowing distally (Fig. 33D).
Female. Total length 1.06; carapace length 0.53; carapace width 0.42; abdomen length 0.59; abdomen width 0.40. Similar to male in color and general features (Figs 34D–E). Chelicerae unmodified. Leg lengths I 1.69 (0.49, 0.15, 0.48, 0.32, 0.26); II 1.57 (0.45, 0.15, 0.44, 0.29, 0.24); III 1.44 (0.42, 0.15, 0.36, 0.28, 0.23); IV 1.92 (0.54, 0.15, 0.54, 0.40, 0.29). Genitalia. Internal genitalia with afferent spermathecae very long, extending past the sides of the abdomen (Fig. 34B); spermathecae oval (Fig. 34A).
