Diagnosis. Males of S. keyserlingi resemble those of S. velox by the palp with cymbium bearing a dorsal proximal hook-shaped projection (DpP, Figs 26 View FIGURES 24–29 , 74 View FIGURES 72–77 ). They are distinguished from the latter species by the RTA long, more than three times longer than wide, surpassing proximal margin of alveolus, distally spoon-shaped (best seen in ventral view) ( Figs 25–26 View FIGURES 24–29 ) (RTA short, two times longer than wide, not surpassing proximal margin of alveolus, with the same width throughout in S. velox ). Females resemble those of S. kaiabi spec. nov. by the epigyne with MS triangular, wider than long, widest anteriorly ( Figs 16 View FIGURES 13–18 , 27 View FIGURES 24–29 ). They are distinguished from those of the latter species by the vulva with FW dilated, four times wider than ducts between first and second turns ( Fig. 28 View FIGURES 24–29 ) (FW slender, slightly wider than the ducts between first and second turns in S. kaiabi spec. nov.).

Redescription. Male (INPA 4563): Total length 15.4. Prosoma: 6.9 long, 6.0 wide. Opisthosoma: 7.5 long, 5.0 wide. Eyes: diameters: 0.55, 0.48, 0.35, 0.46; interdistances: 0.32, 0.12, 0.58, 0.52, 0.33, 0.20. Legs: I: 36.3 (10.0, 3.4, 9.7, 10.5, 2.7); II: 40.8 (11.9, 3.7, 10.7, 11.8, 2.7); III: 27.9 (8.5, 2.9, 7.0, 7.3, 2.2); IV: 31.6 (9.4, 2.8, 8.1, 8.8, 2.5). Spination follows the generic pattern except tibiae I–IV: d0. Palp: RTA longer than wide, apically spoon-shaped (best seen in ventral view); RTA longer than wide; PTA triangular, as long as wide; subtegulum visible prolaterally in ventral view; tegulum oval; conductor almost two times longer than wide, distally fanned and surpassing the anterior margin of the alveolus by half its length; embolus arising from tegulum at 6 o’clock position ( Figs 24–26 View FIGURES 24–29 , 30–32 View FIGURES 30–34 ).

Redescription. Female (MNHN 2459, syntype): Total length 19.9. Prosoma: 6.9 long, 6.6 wide. Opisthosoma: 11.7 long, 7.2 wide. Eyes: diameters: 0.52, 0.40, 0.30, 0.40; interdistances: 0.46, 0.22, 0.66, 0.70, 0.40, 0.34. Legs: I: 29.7 (8.4, 3.6, 7.6, 8.2, 1.9); II: 30.9 (8.9, 3.6, 8.2, 8.3, 1.9); III: 20.4 (6.4, 2.5, 5.2, 4.7, 1.6); IV: 25.4 (7.8, 2.8, 6.3, 6.6, 1.9). Epigyne: EF wider than long; MAB inconspicuous; TP as wide as long as or wider than long; LL touching posteriorly, ( Figs 27 View FIGURES 24–29 , 33 View FIGURES 30–34 ). Vulva: FW mediad; GP small, rounded, arising from ducts at second turn; SP irregularly rounded; FD laterad ( Figs 28–29 View FIGURES 24–29 , 34 View FIGURES 30–34 )

Variation. Males (n = 5): total length 14.0–16.4; prosoma length 6.2–6.9; femur I length 9.1–10.1. Females (n = 9): total length 18.4–24.3; prosoma length 6.9–8.5; femur I length 8.4–9.3.

Distribution. Northern Brazil, states of Amazonas and Pará ( Fig. 90 View FIGURES 89–90 ).
