Material Examined. Holotype: CHINA: Yunnan: Gongshan Co. Dulongjiang Township, Haban Falls 0.5 airkm from Qinlangdang village along Dulong Jiang , 27.67934°N, 98.27291°E, 1265 m, 1 September 2006, forest, rocky outcrops, night, J.A. Miller, D.H. Kavanaugh, JM06090106 (CASENT 9024372, HNU), 1 ♀.

Etymology. Formed from the Chinese word for border (biān jìng), referring to the collection locality on the China-Burma ( Myanmar) border.

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. 31I); distinguished from S. maku by presence of a posterior tubercle on the abdomen and by the path of the fertilization ducts, which run obliquely anteriorly after emerging from the copulatory duct spiral (Fig. 31I; run towards each other in S. bianjing ; Fig. 31H).

Description. Carapace dark brown, lighter in thoracic region. Sternum pale yellow with two brown patches. Legs tan, patellae and distal parts of femora, tibiae, and metatarsi dark brown. Femoral spots on legs I and II. Abdomen dark gray with series of white and tan patches, with pair of unjoined white lines running from spinnerets to prominent posterior tubercle, region between white lines tan with brown chevrons.

Vulva: Epigynum with a small process pointing posteriorly. Copulatory ducts coil around fertilization ducts in nearly longitudinal axis. Fertilization ducts curve obliquely anteriorly after emerging from copulatory duct region (Fig. 31I).

Female (holotype): Total length 0.95, carapace 0.35 long, 0.32 wide, clypeus 0.07, sternum 0.24 long, 0.23 wide, coxa IV separated by 1.75 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: 0.34; TmII: 0.31; TmIII: 0.35. Leg measurements: see Appendix A.

Male unknown.
