Diagnosis. The female of E. frijoles  sp. nov. resembles those of E. nesiotes Chamberlin, 1925  by the shape of the middle field (MF) of the epigynum and by the short and curved spermathecae ( Silva et al. 2008, p. 82, figs 18, 19), but can be distinguished by a smooth middle field of epigynum without excavations ( Fig. 14View FIGURES 12 – 17) and by the conspicuous copulatory openings (CO) ( Fig. 14View FIGURES 12 – 17).
