Etymology. The specific name refers to the Nanay River that borders the type locality; noun in apposition.

Diagnosis. Females of S. nanay spec. nov. resemble those of S. punicea ( Figs 48–50 View FIGURES 45–50 ) by the epigyne with MS diamond-shaped posteriorly ( Fig. 35 View FIGURES 35–40 ). They are distinguished from those of the latter species by the MS more than 1.5 times longer than wide with elliptical CO ( Fig. 35 View FIGURES 35–40 ) and internal ducts loosely twisted, without a well-defined second turn ( Figs 36–37 View FIGURES 35–40 ) (MS less than 1.5 times longer than wide with rounded CO and internal ducts tightly twisted in S. punicea ). Males are unknown.

Description. Female (holotype): Total length 16.3. Prosoma: 7.2 long, 6.4 wide. Opisthosoma: 8.5 long, 4.9 wide. Eyes: diameters: 0.54, 0.41, 0.35, 0.42; interdistances: 0.45, 0.18, 0.70, 0.75, 0.40, 0.35. Legs: I: 28.2 (8.0, 3.4, 7.2, 7.6, 2.0); II: 29.9 (8.9, 3.4, 8.0, 7.6, 2.0); III: 22.2 (7.0, 2.7, 5.4, 5.4, 1.7); IV: 24.2 (7.6, 2.5, 6.0, 6.3, 1.8). Spination follows the generic pattern except patellae II–III: p1. Epigyne: EF as long as wide; MAB inconspicuous; TP wider than long or slightly longer than wide; LL touching posteriorly ( Figs 35 View FIGURES 35–40 , 41 View FIGURES 41–44 ). Vulva: FW antero-laterad; GP cylindrical, longer than wide, arising from duct close to SP; SP irregularly rounded; FD anteriad ( Figs 36–37 View FIGURES 35–40 , 42 View FIGURES 41–44 ).

Male: Unknown.

Variation. Female (n = 2): total length 1.61–16.3; prosoma length 7.2–7.4; femur I length 8.0–8.8.

Distribution. Known from Iquitos in northeastern Peru and southwestern Mato Grosso, in Brazil ( Fig. 89 View FIGURES 89–90 ).
