Diagnosis. Males of S. ravida  resemble those of S. caracarai  sp. nov. and S. chickeringi  by the palp with mRTA represented by small, short, blunt projection, arising from tibia, close to vRTA ( Figs 34View FIGURES 32–38, 50View FIGURES 48–53, 139View FIGURES 137–142). They are distinguished from those of S. caracarai  sp. nov. by slender embolus, with small sub-apical tooth (widened with subapical keel-like projection in S. caracarai  sp. nov.) and from those of S. chickeringi  by TBE with distal projection short and laminar and TBC wide, keel-like, covering base of conductor (TBC with distal projection gutter-shaped and TBC reduced to short keel, not covering base of conductor in S. chickeringi  ) ( Fig. 138View FIGURES 137–142). Females resemble those of S. boraris  sp. nov. and S. caracarai  sp. nov. by the epigyne with anterior atrium smooth, as long as wide, or slightly longer than wide ( Figs 29View FIGURES 26–31, 36View FIGURES 32–38, 140View FIGURES 137–142). They are distinguished from S. boraris  sp. nov. by median septum, widest posteriorly, with posterior margin straight or slightly sinuous and rounded spermathecae (median septum widest anteriorly, with posterior margin rounded and elongate spermathecae in S. boraris  sp. nov.), and from S. caracarai  sp. nov. by the anterior atrium larger than median septum and first turn anteriad (anterior atrium smaller than median septum and first turn mediad in S. caracarai  sp. nov.) ( Figs 140–142View FIGURES 137–142).

Redescription. Male (MPEG 30696): Prosoma brown with thin dark brown lines along thoracic striae; fovea dark brown; eye borders black. Chelicerae brown, as prosoma. Legs and pedipalps lighter than prosoma. Labium and endites brown, distally pale brown. Sternum pale yellowish brown with slightly darker margins. Opisthosoma grayish brown; dorsally with dense pattern of elongate marks laterally, irregular marks around cardiac mark and four median chevrons down posterior half; ventrally with few scattered spots laterally and v-shaped lines of muscle sigilla down most opisthosoma length ( Figs 128–129View FIGURES 128–131). Total length 9.0. Prosoma: 4.5 long, 3.7 wide. Opisthosoma: 4.4 long, 2.9 wide. Eyes: diameters: 0.31, 0.25, 0.14, 0.23; interdistances: 0.25, 0.10, 0.49, 0.33, 0.13, 0.05. Legs (1243): I: 15.5 (4.3, 2.1, 4.1, 40, 1.0); II: 15.1 (4.5, 2.1, 3.7, 3.9, 0.9); III: 11.5 (3.6, 1.8, 2.5, 2.8, 0.8); IV: 14.2 (4.2, 1.5, 3.3, 4.0, 1.2). Spination follows the generic pattern. Metatarsus III with single ventral distal spine, metatarsus IV with ventral distal preening comb. Palp: tibia with prolateral spines short; tegulum with retro-proximal protrusion; TBC wide, keel-like; TBE with distal projection short and laminar; embolus running distally and curving ventral-proximally at the distal margin of the alveolus ( Figs 132–134View FIGURES 132–136, 137–139View FIGURES 137–142).

Redescription. Female (MPEG 15045): Coloration pattern lighter than male; opisthosoma dorsally with median upside down trident-shaped mark on anterior half and five median chevrons down posterior half; ventrally with scattered spots laterally and V-shaped lines of muscle sigilla reaching middle of opisthosoma ( Figs 130–131View FIGURES 128–131). Total length: 10.1. Prosoma: 4.7 long, 3.9 wide. Opisthosoma: 5.2 long, 3.3 wide. Eyes: diameters 0.32, 0.25, 0.18, 0.24; interdistances: 0.26, 0.17, 0.47, 0.38, 0.16, 0.07. Legs (12/43): I: 14.0 (4.1, 2.2, 3.7, 3.3, 0.7); II: 13.5 (4.2, 2.0,.3.3, 3.3, 0.7); III: 10.7 (3.5, 1.8, 2.2, 2.5, 0.7); IV: 13.5 (4.0, 1.7, 3.0, 3.7, 1.1). Spination follows the generic pattern. Metatarsus III–IV with ventral distal preening combs. Epigyne: epigynal field squared, as wide as long; median septum longer than wide ( Figs 135View FIGURES 132–136, 140View FIGURES 137–142). Vulva: internal ducts slender, half spermathecae width; glandular projection arising from ducts at first turn ( Figs 136View FIGURES 132–136, 141–142View FIGURES 137–142).

Variation. Males (n = 10): total length 7.7–9.6; prosoma length 3.8–4.5; femur I length 3.6–4.3. Females (n = 10): total length 9.1–12.4; prosoma length 3.9–4.8; femur I length 3.3–4.1.

Distribution. Known from northern South America ( Brazil, Ecuador and Guyana) and from the Isle of St. Vincent ( Fig. 144View FIGURES 143–144).
