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

Diagnosis. Males of Scytodes chopim n.sp. are distinguished from those of the remaining Neotropical Scytodes by the palp with prolaterally concave distal region ( Fig. 113 ) and retrolateral dorsal hyaline keel ( Fig. 114–115 ). The females are distinguished by the slightly oval and medially fused hyaline pockets with very narrow lateral sclerotized areas ( Fig. 117 ).

Description. Male (Holotype, IBSP 21347). Carapace orange with dark brown pattern as shown on Fig. 112 . Chelicerae orange with median longitudinal brown stripe. Pedipalps pale yellow with brown prolateral and dorsal stains. Labium orange with pale brown base. Endites pale yellow. Sternum cream colored with brown markings in front of each coxae. Legs pale yellow. Femora I–IV with ventral pair of longitudinal black stripes. Tibiae I–IV with median transversal black band. Abdomen gray. Posterior half with black pattern ( Fig. 112 ). Total length 4.0. Carapace slightly domed, 2.3 long, 1.9 wide. Eye diameters: PME 0.14, ALE 0.12, PLE 0.12. Lateral eyes on a tubercle. Chelicerae with subapical hyaline keel and inconspicuous stridulatory ridges. Labium 0.12 long, 0.22 wide. Sternum 1.2 long, 0.9 wide. Leg measurements: I: femur 5.4, patella 0.5, tibia 5.9, metatarsus 7.2, tarsus 0.8, total 19.8; II: 3.8, 0.5, 3.9, 4.6, 0.6, 13.4; III: 1.8, 0.5, 2.2, 2.6, 0.5, 7.6; IV: 3.6, 0.5, 3.3, 3.9, 0.7, 12.0. Palpal femur with stridulatory pick long and slender on slightly triangular and projected socket. Cymbium with a strong distal spine ( Fig. 113 ). Bulb 0.64 long, slightly bent and medially narrowed. Distal region with retrolateral-dorsal hyaline keel and short sclerotized process ( Figs. 114–115 ). Abdomen 1.7 long, 1.5 wide, covered with short slender hairs.

Female (Paratype, IBSP 9798) Coloration pattern as in male. Total length 4.8. Carapace slightly domed, 2.4 long, 2.1 wide. Eye diameters: PME 0.12, ALE 0.12, PLE 0.14. Lateral eyes on a tubercle. Chelicerae as in male. Labium 0.18 long, 0.28 wide. Sternum 1.28 long, 0.90 wide. Leg measurements: I: femur 3.5, patella 0.6, tibia 3.6, metatarsus 4.6, tarsus 0.7, total 13.0; II: 2.7, 0.6, 2.3, 2.7, 0.5, 8.8; III: 1.8, 0.6, 1.5, 1.9, 0.6, 6.4; IV: 2.6, 0.6, 2.5, 2.8, 0.6, 9.1. Palpal femur as in male. Epigynum with ridged positioning ridges separated from each other by 2–3 times their width ( Fig. 116 ). Vulva with small and rounded spermathecae, with narrow stalks, adjacent to slightly oval and medially fused hyaline pockets and very narrow lateral sclerotized areas ( Fig. 117 ). Abdomen 2.4 long, 2.0 wide, as in male.

Variation. Ten males: total length 3.0–4.2; carapace 1.7–2.3; femur I 3.6–5.8; bulb 0.46–0.66. Ten females: total length 3.8–5.9; carapace 1.9–2.5; femur I 2.1–3.9.
