Etymology. The specific name is a noun in apposition and refers to the type locality of the holotype.

Diagnosis. Males of Scytodes bonito   n.sp. are distinguished from those of the remaining Neotropical Scytodes   by the palp with a retrolateral, serrated, laminar projection ( Figs. 64–65 View FIGURES 62 – 73. 62 – 67 ). The females are distinguished by the round spermathecae on long and curved stalks and fused hyaline pockets, with lateral sclerotized areas ( Fig. 67 View FIGURES 62 – 73. 62 – 67 ).

Pedipalps pale yellow with lateral brown markings. Labium and endites pale yellow. Sternum pale yellow with black markings in front of each coxae. Legs pale yellow. Femora I –IV with pair of longitudinal ventral black stripes. Patellae, tibiae and metatarsi distally black. Abdomen gray with dark gray pattern ( Fig. 62 View FIGURES 62 – 73. 62 – 67 ).

Bulb 0.86 long, very slightly curved medially. Distal region concave ( Figs. 63–65 View FIGURES 62 – 73. 62 – 67 ) with retrolateral hyaline keel, serrated, laminar projection and sclerotized process ( Figs. 64–65 View FIGURES 62 – 73. 62 – 67 ). Abdomen 1.8 long, 1.2 wide, covered with slender hairs.

Female (Paratype, IBSP 92455). Coloration pattern as in male. Total length 4.8. Carapace domed, 2.5 long, 1.9 wide. Eye diameters: PME 0.14, ALE 0.16, PLE 0.16. Lateral eyes on a tubercle.

Leg measurements: I: femur 3.7, patella 0.6, tibia 3.0, metatarsus 4.3, tarsus 0.7, total 12.3; II: 2.6, 0.5, 2.6, 3.1, 0.5, 9.3; III: 1.9, 0.5, 1.5, 2.0, 0.5, 6.4; IV: 2.6, 0.5, 2.5, 2.6, 0.7, 8.9. Palpal femur as in male. Epigynum with narrow, slightly curved positioning ridges and narrow foveas separated from each other by more than ten times their width ( Fig. 66 View FIGURES 62 – 73. 62 – 67 ). Vulva with round spermathecae on long and curved stalks and fused hyaline pockets, with lateral sclerotized areas ( Fig. 67 View FIGURES 62 – 73. 62 – 67 ). Abdomen 2.4 long, 1.9 wide, as in male.
