Figs 12 ̄14, Map 1

Type material. Male holotype ( AMNH) from Colombia, Ovalle leg. ( Poorly preserved, dehydrated, abdomen missing, legs broken).

Etymology. The specific name refers to a music stile typical from Colombia, the cúmbia .

Diagnosis. Males of E. cumbia n. sp. resemble those of E. ravidus , E. itamaraju and E. nancyae n. sp. ( Figs 58 ¯60; Bonaldo 1994: figs 65, 70) by the flattened embolus, with distal prolateral process, but differ by the long MA, with the apex unfolded and prolaterally oriented, and by the RTA with dorsal prong shorter than the ventral prong ( Figs 12 , 14).

Description. Male (Holotype). Colour in ethanol, dried specimen: carapace brownish red, thoracic groove brownish, chelicerae brownish red. Endites, labium and sternum brownish red. Legs orange. Chelicerae with 3 promarginal teeth, the second the largest, the last a denticle, and 4 retromarginal teeth, the first a denticle, separated by twice their width from second, second to fourth separated by their width. Tarsi I–II with moderate scopulae, tarsi III–IV and metatarsi III–IV with dense scopulae. Carapace 6.2 long, 4.9 wide. Eye diameters: AME 0.37, ALE 0.33, PME 0.24, PLE 0.31. Eye interdistances: AME–AME 0.28, AME–ALE 0.33, PME–PME 0.46, PME–PLE 0.68, AME–PME 0.32, ALE–PLE 0.15, clypeus AME 0.24, clypeus ALE 0.28. Leg and palp measurements: palp 6.7 (2.4, 1.0, 1.0, -, 2.3); leg I 20.12 (5.2, 2.5, 5.0, 5.4, 2.5); leg II 19.7 (5.3, 2.4, 4.7, 5.1, 2.2); leg III 15.08 (4.4, 2.0, 3.6, 4.1, 1.7); leg IV 19.9 (5.5, 2.2, 4.5, 5.6, 2.1).

II—femur d 0, p 0-0-d1, r 0; tibia d 0, p 0, r 0, v 0-p1-0; metatarsus d 0, p 0, r 0, v 0. III—femur d 1-1-0, p 0-0-d1, r 0; tibia d 0, p 1-1, r 0-1, v 0-p1-0; metatarsus d p1r1-p1r1-p1r1, p 0-0-1, r 0-0-1, v 2-2 -1.

Palp: Tibia slender, two-thirds the cymbium length; RTA large, bifid, divided at base, C-shaped; MA apically placed, apex unfolded, directed prolaterally, median prong absent; conductor hyaline; embolus inserted sub-basally, not fused to tegulum, flattened, with apical prolateral process ( Figs 12 ̄14).
