Material Examined. Holotype: CHINA: Yunnan: Gongshan Co. Dulongjiang Township, Maku ridge, 27.67509°N, 98.30160°E, 1950 m, 30 August 2006, forest, rocky outcrops, night, J.A. Miller, D.H. Kavanaugh, JM06083001 (CASENT 9024429, HNU), 1 ♀.

Etymology. The epithet is derived from the type locality.

Diagnosis. Distinguished from S. yaojia and S. kavanaugh by the presence of a small posteriorly projecting process on the epigynum and the lack of a transverse anterior lobe (Fig. 31H); distinguished from S. bianjing by the lack of a posterior tubercle on the abdomen and by the path of the fertilization ducts, which run towards each other after emerging from the copulatory duct spiral (Fig. 31H; run obliquely anteriorly in S. bianjing ; Fig. 31I).

Description. Carapace pale thoracic region, brown head region. Sternum brown. Legs orange, darker patellae and distally on femora, tibiae, metatarsi, and tarsi. Femoral spot on leg I. Abdomen dark gray with pair of white patches dorsally and pair of unjoined longitudinal white lines laterally; posterior tubercle absent.

Vulva: Epigynum with a small process pointing posteriorly (Fig. 31G). Copulatory ducts coil around fertilization ducts in nearly longitudinal axis. Fertilization ducts run toward each other after emerging from copulatory duct region (Fig. 31H).

Female (holotype): Total length 0.87, carapace 0.35 long, 0.33 wide, clypeus 0.08, sternum 0.24 long, 0.23 wide, coxa IV separated by 1.69 times their width. Leg I: patella d1, tibia d1; Leg II: patella d1, tibia d1; Leg III: patella d1, tibia d1; Leg IV: patella d1, tibia d1. Metatarsal trichobothria: TmI: 0.32; TmII: 0.33; TmIII: 0.36. Leg measurements: see Appendix A.

Male unknown.
