Sadala nanay spec. nov. Figs 35–37, 41–42, 89 Type material: Holotype: PERU: Iquitos: ♀, San Juan Bautista, Zungarococha, Arboretum del UNAP (-3.8298, -73.3753), 8–9 April 2013, C.A. Rheims & R. P. Indicatti leg. (MUSM). Paratype: BRAZIL: Mato Grosso: 1♀, Pontes e Lacerda / Vale do São Domingos, Usina Hidrelétrica de Guaporé [‑15.133, ‑58.9667], October 1999, Equipe Butantan leg. (IBSP 41397). 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) by the epigyne with MS diamond-shaped posteriorly (Fig. 35). 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) and internal ducts loosely twisted, without a well-defined second turn (Figs 36–37) (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, 41). Vulva: FW antero-laterad; GP cylindrical, longer than wide, arising from duct close to SP; SP irregularly rounded; FD anteriad (Figs 36–37, 42). 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).
