Other material examined. BRAZIL. São Paulo: Santos [23°51'53.1"S; 46°18'15.7" W] (Vale do Rio Jurubatuba ), 43, March - December 2007, A.A. Nogueira et al. ( IBSP 92526; 92525; 92518; 92516); Bertioga [23°51' S; 46°08' W] (Trilha do Rio Itatinga), 13, July 2000, M.S.C. Morini ( IBSP 62357).

Etymology. The specific name is a noun in apposition that refers to the type locality of one of the paratypes.

Diagnosis. Males of Scytodes jurubatuba n.sp. resemble those of S. bocaina n.sp. ( Figs. 91–92 ) by the short and distally narrowed bulb. They are distinguished by the slightly bent bulb with distal region slender and concave ( Fig. 87 ) slightly shorter than the retrolateral sclerotized process ( Figs. 88–89 ).

Palpal tibiae with a dorsal and a prolateral longitudinal brown stripe. Labium pale yellow. Endites yellow with pale brown margins. Sternum yellow with orange margins and brown markings in front of each coxae. Legs orange. Femora I–IV with pair of ventral longitudinal brown stripes. Tibiae I–IV with brown extremities. Abdomen gray with black pattern ( Fig. 86 ). Total length 3.4. Carapace slightly domed, 1.7 long, 1.5 wide. Eye diameters: PME 0.14, ALE 0.14, PLE 0.14. Lateral eyes on a tubercle. Chelicerae with subapical hyaline keel and inconspicuous stridulatory ridges. Labium 0.12 long, 0.26 wide. Sternum 0.92 long, 0.80 wide. Leg measurements: I: femur 3.2, patella 0.5, tibia 3.5, metatarsus 4.3, tarsus 0.6, total 12.1; II: 2.5, 0.5, 2.3, 2.8, 0.5, 8.6; III: 1.5, 0.4, 1.4, 1.6, 0.5, 5.4; IV: 2.3, 0.5, 2.0, 2.4, 0.5, 7.7. Palpal femur with long and slender stridulatory pick on triangular and projected socket. Cymbium with pair of strong distal spines ( Fig. 87 ). Bulb 0.60 long, short and subdistally bent. Distal region slender and concave ( Fig. 87 ) with retrolateral, subdistal sclerotized process ( Figs. 88–89 ). Abdomen 1.7 long, 1.2 wide, covered with slender hairs.

Female unknown.
