Diagnosis.Females of S. nigristernisresemble those of S. velox( Figs 75–77) by the epigyne with MS roughly trapezoid, widest medio-anteriorly ( Fig. 38). They are distinguished from those of the latter species by the MS two times longer than wide and margins of CO oblique ( Fig. 38) (MS as long as wide and margins of CO roughly longitudinal in S. velox). Males are unknown.
Redescription. Female ( holotype):Total length 19.4. Prosoma: 7.9 long, 7.3 wide. Opisthosoma: 10.8 long, 3.7 wide. Eyes: diameters: 0.58, 0.44, 0.30, 0.45; interdistances: 0.48, 0.20, 0.74, 0.70, 0.48, 0.32. Legs: I: 32.9 (9.2, 3.7, 8.7, 9.0, 2.3); II: 34.6 (10.1, 3.8, 9.1, 9.4, 2.2); III: 25.7 (8.0, 3.3, 6.4, 6.1, 1.9); IV: 28.4 (8.7, 3.0, 7.0, 7.6, 2.1). Spination follows the generic pattern. Epigyne: EF longer than wide; MAB embedded in EF; TP two times longer than wide; LL touching posteriorly ( Figs 38, 43). Vulva: FW antero-mediad; GP cylindrical, slightly longer than wide, arising from ducts at second turn; SP irregularly rounded; FD antero laterad ( Figs 39–40, 44). Male:Unknown. Variation.Females (n = 9): total length 16.0–23.7; prosoma length 7.2–8.2; femur I length 8.3–10.0.
Distribution.Known from northern and central Brazil, states of Amazonas, Acre, Rondônia, Pará and Mato Grosso( Fig. 90).
