Diagnosis. Males of S. velox resemble those of S. keyserlingi (Figs 24–26) by the palp with cymbium bearing a dorsal proximal hook-shaped projection (DpP, Fig. 74). They are distinguished from the latter species by the RTA short, two times longer than wide, not surpassing proximal margin of alveolus, with the same width throughout (Fig. 73) (RTA long, more than three times longer than wide, surpassing proximal margin of alveolus, distally spoon-shaped in S. keyserlingi). Females resemble those of S. nigristernis (Figs 38–40) by the epigyne with MS roughly trapezoid, widest anteriorly (Fig. 75). They are distinguished from the latter species by the MS as long as wide and margins of CO roughly longitudinal (Fig. 75) (MS two times longer than wide and margins of CO oblique in S. nigristernis).
Redescription. Male (MZSP 34550): Total length 13.4. Prosoma: 6.1 long, 5.7 wide. Opisthosoma: 7.0 long, 4.0 wide. Eyes: diameters: 0.56, 0.41, 0.30, 0.39; interdistances: 0.23, 0.07, 0.53, 0.53, 0.34, 0.20. Legs: I: 34.1 (9.4, 3.2, 9.0, 10.0, 2.5); II: 36.0 (10.1, 3.4, 9.5, 10.5, 2.5); III: 25.7 (7.8, 2.7, 6.5, 6.7, 2.0); IV: 28.9 (8.5, 2.6, 7.5, 8.0, 2.3). Spination follows the generic pattern except tibia III: d1-0-1; patella IV: p1. Palp: RTA two times longer than wide, concave, distally blunt; PTA triangular, as long as wide; subtegulum visible prolaterally in ventral view; tegulum oval; conductor 3.5 times longer than wide, surpassing the anterior margin of alveolus by 1/3 its length; embolus arising from tegulum at 5:30–6 o’clock position (Figs 72–74, 78–80).
Female (MZSP 34862): Total length 17.7. Prosoma: 7.5 long, 6.8 wide. Opisthosoma: 9.5 long, 5.5 wide. Eyes: diameters: 0.55, 0.42, 0.35, 0.45; interdistances: 0.45, 0.30, 0.75, 0.73, 0.40, 0.32. Legs: I: 31.0 (8.7, 3.6, 7.9, 8.6, 2.2); II: 32.4 (9.4, 3.7, 8.5, 8.5, 2.3); III: 23.8 (7.4, 3.0, 5.7, 5.9, 1.8); IV: 26.4 (8.1, 2.8, 6.5, 7.0, 2.0). Spination follows the generic pattern. Epigyne: EF as long as wide; MAB inconspicuous; TP as wide as long (Figs 75, 81). Vulva: FW antero-mediad; GP longer than wide, arising from ducts at second turn; SP spherical; FD antero-laterad (Figs 76–77, 82).
Variation. Males (n = 10): total length 11.0–14.5; prosoma length 5.0–6.2; femur I length 8.3–9.6. Females (n = 10): total length 15.4–22.8; prosoma length 7.1–8.8; femur I length 7.8–10.2.
Distribution. North and northwestern South America (French Guyana, Brazil and Peru) (Fig. 89)
