Eye sizes and interdistances: AME = 0.21, ALE = 0.17, PME = 0.49, PLE = 0.39; AME – AME = 0.11, AME – ALE = 0.09, PME – PME = 0.32, PME – PLE = 0.35. Clypeus height 0.16. LEG MEASUREMENTS. I = 13.35 (3.81, 4.33, 3.01, 2.20); II = 12.75 (3.55, 4.33, 2.95, 1.92); III = 11.82 (3.33, 3.65, 3.11, 1.73); IV = 16.98 (4.50, 4.84, 5.26, 2.38). MALE PEDIPALP (Figs 1, 2 A – B, 3 C – F). Subtegulum distinct in ventral view, located baso-prolaterally. Embolus slender and slightly sinuous. Conductor small and membranous. Median apophysis serrated, ventral surface with semicircular protruding lobe, strongly sclerotized, dorsal surface with oval sclerite. Terminal apophysis strong twisted, distal end grooved.

diagnosis
Diagnosis This new species most closely resembles S. multidontata (Qu, Peng & Yin, 2010) (Figs 4 – 5), but differs from the latter by the following characters. Lateral projection of the median apophysis with a blunt end, slightly touching lateral edge of cymbium in the new species (Figs 1 C – D, 2 A – B, 3 C – F), whereas distal end truncate, almost overlapping lateral edge of cymbium in ventral view in S. multidontata (Figs 4 A – B, 5 C – F). Septum wider than long and spermathecal heads spherical with fine spermathecal stalks in the new species (Figs 2 C – D, 3 G – H), whereas septum longer than wide and spermathecal heads oval with thick spermathecal stalks in S. multidontata (Figs 4 C – D, 5 G – H).
