Diagnosis. Males of E. madre  resemble those of E. paredesi  n. sp. and E. marquesae  by the MA with a long, retrolaterally directed median prong ( Figs 1View FIGURES 1, 27View FIGURES 27) but can be distinguished from the former by the presence of an embolar prolateral process and from the later by that process being inserted sub-apically ( Figs 23View FIGURES 23, 24). Females share with those of E. marquesae  the relatively small epigynal anterior projections, presenting a semi-circular sclerotized area at its inner margin, and posterior plates projected anteriorly over the median field ( Fig. 52View FIGURES 52; Bonaldo 1994: fig. 80). They differ by the larger semi-circular sclerotized area on the anterior projections, which are projected over the posterior plates ( Bonaldo 1994: fig. 79).

Description. Male ( MPEG 21927). Colour in ethanol: carapace brownish red, cephalic region darker, thoracic groove mark reddish. Chelicerae, endites and labium brownish red. Sternum orange with brown margins. Legs yellow. Chelicerae with 4 promarginal teeth, the third the largest, the first a denticle; and 4 closely placed retromarginal teeth. Tarsi III –IV with dense scopulae, metatarsi III –IV with moderate scopulae. Total length 10.1. Carapace 5.0 long, 3.8 wide. Eye diameters: AME 0.28, ALE 0.27, PME 0.24, PLE 0.26. Eye interdistances: AME –AME 0.29, AME –ALE 0.31, PME –PME 0.40, PME –PLE 0.55, AME –PME 0.30, ALE –PLE 0.10, clypeus AME 0.17, clypeus ALE 0.17. Leg and palp measurements: palp 5.4 (2.0, 0.6, 1.2, -, 1.6); leg I missing; leg II missing; leg III 13.4 (3.7, 1.6, 3.0, 3.6, 1.5); leg IV 19.6 (4.8, 1.9, 3.9, 5.0, 1.7). Spination: palp femur: d 0-1-1; tibia p 2-0. Leg. I absent. II—absent. III—femur d 1-1-0, p 0-d1-d1, r 0-d1-d2; tibia d 0, p 2-1, r 1-1, v 2-2 -2; metatarsus d p1r1-p1r1-p1r1, p 0-0-1, r 0-0-1, v 2-2 -1. IV—femur d 1-1-0, p 0-d1-d1, r 0-0-d1; tibia d 0, p 1-1, r 1- 1, v 2-2 -2; metatarsus d p1r1-p1r1-p1r1, p 0-0-1, r 0-0-1, v 2-2 -1. Palp: tibia thin, long, almost the same length of cymbium; RTA excavated, projected retrolaterally. Tegular process absent; MA apically placed, median prong large; conductor hyaline. Embolus inserted sub-basally; embolus long, thin, base rounded, prolateral process hyaline, apices hook-shaped ( Figs 23View FIGURES 23 ̄25).

Female. Described by Bonaldo (1994: 129). Complementary description: vulva composed by large primary spermathecae with short fertilization ducts; secondary spermathecae inconspicuous (Fig. 26).
