Type material: Holotype: male from Serra de São José, Feira de Santana, Bahia, Brazil, 12º08’S, 39º01’W, 22.VIII.2009 – 09.VIII.2010, G. da S.C. Ferreira (IBSP 160759). Paratype: 1 male and 1 female, same data as holotype, IBSP 160766, 160763.

Additional material examined. BRAZIL: Bahia: 11 males and 1 female, Feira de Santana, Serra de São José, 22.VIII.2009 – 09.VIII.2010, G. da S.C. Ferreira (IBSP 160760–160762, 160764–160765, 160767–160771, UEFS).

Etymology. The specific epithet is a Latin combination in apposition and refers to the long ventral spines on front legs.

Diagnosis. This species is similar to S. lunatus sp. nov. by having long spines on front legs, a reduced embolus in the male palp and four spermathecae in the epigyne, but can be distinguished from that species by the stouter embolus in the male palp (see Figs 24, 28) and by having a longer duct connecting the secondary and the primary spermathecae in the epigyne (see Figs 27, 31, 32–33).

Description. Male holotype: Total length: 3.10. Carapace dark brown, 1.60 long, 1.10 wide, 0.70 high (Figs 34, 53–54). Ocular quadrangle 0.85 long. Anterior eye row 1.15 wide and posterior 1.00 wide. Chelicera dark brown. Labium and sternum dark brown. Endite dark brown, slightly projected laterally. Palp dark brown, with a short RTA, tegulum projected proximally and with a distal bump, and short, distal embolus (Figs 28–29). Legs 4132, dark brown, except for metatarsi II–IV and tarsi I–IV yellow. Length of femur: I 1.02, II 0.77, III 0.97, IV 0.92; patella + tibia: I 1.20, II 0.87, III 1.00, IV 1.05; metatarsus + tarsus: I 0.85, II 0.77, III 1.00, IV 1.12. Spination as in S. lunatus sp. nov. Abdomen as in S. lunatus sp. nov. Spinnerets light brown.

Female (paratype IBSP 160763): Total length: 3.20. Carapace dark brown, 1.55 long, 1.10 wide, 0.75 high (Fig. 35). Ocular quadrangle 0.77 long. Anterior eye row 1.10 wide and posterior 1.00 wide. Chelicera light brown. Endite, labium and sternum light brown. Palpal femur dark brown, rest light brown. Legs 4312; femora dark brown and patellae yellow with dark brown borders; tibia I yellow with dark brown prolateral and retrolateral sides; II–IV yellow with dark brown rings proximally and distally; metatarsi and tarsi yellow. Length of femur: I 0.87, II 0.75, III 0.80, IV 0.87; patella + tibia: I 1.07, II 0.82, III 0.95, IV 1.00; metatarsus + tarsus: I 0.75, II 0.70, III 0.95, IV 1.15. Spination as in S. lunatus sp. nov. Abdomen dark gray (Fig. 35). Epigyne with anterior, semicircular copulation opening (for a better understanding of this complex epigyne, epigynal structures mentioned here refer to only one of the sides); a short copulation duct leads to a bifurcation, in which scent glands open; to the ventral side of the bifurcation, there is an elliptical secondary spermatheca; to the dorsal side, there is a sinuous duct leading to the primary spermatheca; pores of nutritive glands are present on the wall of the primary spermatheca, beside which the fertilization duct arises (Figs 30–31, 33). Spinnerets dark brown.

Variation. Carapace length: 1.26–1.70 (males, n=13), 1.60–1.70 (females, n=2). Some specimens have a more complex abdominal pattern, such as that of the paratype (Fig. 34)

Distribution. Known only from the State of Bahia, Brazil.

Biological note. The specimens were collected from the ground using pitfall traps.
