Diagnosis. Males of S. crulsi  resemble those of S. beebei  sp. nov. by the palp with mRTA sickle-shaped, arising from base of dRTA ( Figs 13View FIGURES 11–16, 65View FIGURES 63–68). They are distinguished from the latter species by TBE with apical projection short and laminar (apical projection resembling a fishtail in S. beebei  sp. nov.) ( Fig. 64View FIGURES 63–68). Females are distinguished from other congeners by the epigyne with lateral furrows distinctly separated from anterior furrow ( Figs. 61View FIGURES 58–62, 66View FIGURES 63–68), internal ducts with first turn anteriad and glandular projection almost as large as spermathecae ( Figs. 67–68View FIGURES 63–68).

Redescription. Male (MNHN): Prosoma brown, darker at eye area and along thoracic striae. Chelicerae brown, darker than prosoma. Labium and endites yellowish brown. Sternum pale yellowish brown with darker margins. Opisthosoma pale gray; dorsally with brownish gray pattern of few scattered irregular marks laterally and 1–2 chevrons on posterior half; cardiac mark area lighter; ventrally with V-shaped lines of muscle sigilla extending posteriorly along almost all opisthosoma length ( Figs 54–55View FIGURES 54–57). Total length: 7.8. Prosoma: 3.8 long, 2.8 wide. Opist-hosoma: 3.7 long, 2.0 wide. Eyes: diameters: 0.33, 0.20, 0.15, 0.20; interdistances: 0.20, 0.02, 0.45, 0.20, 0.15, 0.06. Legs (1/423): I: 12.0 (3.5, 1.7, 3.1, 2.9, 0.8); II: 11.7 (3.4, 1.7, 3.0, 2.8, 0.8); III: 8.9 (2.8, 1.0, 2.1, 2.3, 0.7); IV: 12.0 (3.5, 1.3, 2.7, 3.4, 1.1). Spination follows the generic pattern. Metatarsi III–IV with ventral distal preening combs. Palp: tibia with prolateral spines long; tegulum with retro-proximal protrusion; TBE squared with apical projection short and laminar; TBC wide, keel-like; embolus slender, with no projections, running distally and curving ventralproximally at the distal margin of alveolus ( Figs 58–60View FIGURES 58–62, 63–65View FIGURES 63–68).

Description. Female (MNHN): Coloration pattern darker than male. Opisthosoma dorsally with two pairs of brown, round, muscular impressions on anterior half and brown pattern of irregular, elongate marks laterally (more than in male), large, irregular mark at the posterior end of cardiac mark and five median triangular marks down posterior half; ventrally with few scattered spots on posterior half; muscle sigilla inconspicuous ( Figs 56–57View FIGURES 54–57). Total length: 9.9. Prosoma: 3.9 long, 3.2 wide. Opisthosoma: 5.8 long, 2.9 wide. Eyes: diameters: 0.26, 0.21, 0.15, 0.20; interdistances: 0.20, 0.09, 0.42, 0.33, 0.12, 0.11. Legs (21/43): I: 10,7 (3.1, 1.8, 2.6, 2.5, 0.7); II: 10.9 (3.3, 1.7, 2.6, 2.6, 0.7); III: 9.4 (2.9, 1.4, 2.4, 2.1, 0.6); IV: 10.7 (3.1, 1.3, 2.5, 2.9, 0.9). Spination pattern follows the generic pattern except tibia III: p1-0-0; tibia IV: d0-0-1; metatarsus IV: p1-1-0. Metatarsus III–IV with ventral distal preening combs. Epigyne: epigynal field rectangular, longer than wide; anterior furrow straight, slightly bent at lateral tips ( Figs 61View FIGURES 58–62, 66View FIGURES 63–68). Vulva: internal ducts one third spermathecae width from copulatory openings to first turn and as wide as spermathecae from first turn to spermathecae; glandular projection arising from duct close to base of spermathecae; spermathecae oval ( Figs 62View FIGURES 58–62, 67–68View FIGURES 63–68).

Variation. Males (n=2): total length 7.4–7.8; prosoma length: 3.4–3.8; femur I length: 3.0–3.4. Females (n = 2): total length: 9.9–10.6; prosoma length: 3.9–4.7; femur I length: 3.1–3.9.

Distribution. Known from western state of Pará ( Brazil), French Guiana and Trinidad ( Fig. 144View FIGURES 143–144).
