Figures 7 , 9 , 10F , 11A

Types. Female holotype ( MNHNSD 09.1617 ) from Parque Nacional Armando Bermúdez (19°03'59.79"N– 71°02'5.70"W), 1790 m, Valle de Bao , Province Santiago, Dominican Republic, 11–12.VII.2015, C. Suriel, C. Marte & G. de los Santos. Paratypes: two females ( MNHNSD 09.1618 and MNHNSD 09.1619 ), same data as holotype .

Etymology. The specific name is a patronym in honor of the American arachnologist Elizabeth B. Bryant.

Diagnosis. Females resemble those of S. armasi sp. n. by having an atrial hood projected ( Figs 6D , 7A ), but can be distinguished by having it smaller and heavily sclerotized, covering only part of anterior edges of epigynal posterior plates ( Fig. 7 D–E).

Description. Male: Unknown. Female (holotype MNHNSD 09.1617): carapace orange, with gray paramedian bands ( Fig. 10F ). Chelicerae red brown with its inner distal part orange. Labium, endites and sternum dark orange. Palp orange, claw with three teeth. Legs orange with metatarsus and tarsus dark orange. Abdomen dorsally gray with white spots ( Fig. 10F ), ventrally yellow. Total length 11.6, carapace length 5.4, width 3.8. Eye diameters: AME 0.16, ALE 0.18, PME 0.20, PLE 0.20. Chelicerae 2.2 long, with 3 promarginal and 2 retromarginal teeth. Leg femur length: I—3.9; II—3.8; III—3.3; IV—4.4. Palp: claw with three teeth ( Fig. 7C ); spination: patella p1; tibia p2-1-0, d0-1-1; tarsus v0-0-2, p2-1-0, r1-1-0, d0-1-0. Leg spination: I—tibia v2-2-2, p0, r0, d0, metatarsus v2-2-0, p0, r0, d0; II—tibia v1-1-2, p0, r0, d0, metatarsus v2-2-0, p0, r0, d0; III—tibia v1-2-1, p0-1-1, r1-1-0, d1-1-0, metatarsus v2-2-1, p1-1-1, r1-1-0, d2-2-2; IV—tibia v2-1-2, p1-1-0, r1-1-0, d0, metatarsus v2-2-2, p1-1-0, r1-1-1, d2-2-2. Epigynum: atrial hood projected, small and heavily sclerotized, just covering part of anterior edges of epigynal posterior plates ( Fig. 7 D–E); primary spermathecae coiled; secondary spermathecae projected internally; fertilization ducts smaller than spermathecae and C-shaped copulatory ducts ( Fig. 7 A–B).

Distribution. Known only from the highland savanna found in the type locality ( Fig. 9 ).
