Diagnosis. Glp-1 same level as Ds-1. Ds-2 on membranous cuticle. PE without dorsal seta. GA bipartite in female. Female with 6 Pgs and 4 Sgs. Tr I–IV with 1-1-1-1 setae; Bf I–IV with 1-1-1-1 setae; Tf I–IV with 6-5-2-2 setae, 3-(1,2)-0-0 Bp setae; Gn I–IV with 5-4-3-3 setae, 2-1-0-0 Bp setae; Tb I–IV with 9-5-6-6 setae, 5-2-3-3 Bp setae; Ta I–IV with 3-3-3-3 dorsal setae, 1-1-0-0 Bp setae. Lc I with unidentate accessory process. Idiosoma length 248–343 in female. Idiosoma width 195 (idiosoma length 255) in female. Gnathosoma length 214–229 in female. Gnathosoma width 117 (gnathosoma length 214) in female. Ratio of gnathosoma to idiosoma 0.84 in female. Ratio of P-2 to P-1 2.73.
Remarks. This species closely resembles S. punctatus, however, differs from the latter by the presence of pitted areolae on almost all of the leg segments, instead of only on Tf in S. punctatus. Female is known.
