Diagnosis. Males of Scytodes jurubatuba   n.sp. resemble those of S. bocaina   n.sp. ( Figs. 91–92 View FIGURES 86 – 93. 86 – 89 ) by the short and distally narrowed bulb. They are distinguished by the slightly bent bulb with distal region slender and concave ( Fig. 87 View FIGURES 86 – 93. 86 – 89 ) slightly shorter than the retrolateral sclerotized process ( Figs. 88–89 View FIGURES 86 – 93. 86 – 89 ).

Pedipalps orange. 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 View FIGURES 86 – 93. 86 – 89 ). 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.

Bulb 0.60 long, short and subdistally bent. Distal region slender and concave ( Fig. 87 View FIGURES 86 – 93. 86 – 89 ) with retrolateral, subdistal sclerotized process ( Figs. 88–89 View FIGURES 86 – 93. 86 – 89 ). Abdomen 1.7 long, 1.2 wide, covered with slender hairs.

Female unknown.
