Diagnosis. Within the genus, E. eliethae  n. sp. can be recognized by the following characters: male FWs dark brown, broadly rounded, margins light brown; covering metanotal gland area and surpassing the metanotum; secondary veins well visible, medium brown; internal margins touching each other only at anterior half, slightly overlapping; glandular thickening absent. Metanotal gland present, with a cluster of bristles and two short projections with rounded top. Apex of pseudepilhallic arms with two dorsal, and a ventral projection; dorsal projections of the apex pointed, one curved inwards, other up-curved; ventral projection thin, elongate, pointed, almost straight; ectophallic arc located posteriorly to the median part of pseudepiphallus, near the PsP 2; dorsal projections of ectophallic invagination (D.P.Ec.) short, sclerotized, clearly separated.

Thorax. Pronotum DD wider than long, dark bworn, with sparse dark spots and maculae, slightly pubescent, divided by a distinct light brown sagittal line, and another four light brown, thick lines ( Fig. 10View FIGURE 10 C); DD cephalic margin sub-straight, caudal margin slightly concave ( Fig. 10View FIGURE 10 C); ventro-cephalic angle slightly rounded, ventrocaudal margin gradually ascendant ( Fig. 10View FIGURE 10 B). Male FWs dark brown, short, but longer than in E. simoesi  n. sp., rounded, margins light brown ( Fig. 10View FIGURE 10 C); covering metanotal gland area and surpassing the metanotum ( Figs. 10View FIGURE 10 B, C); posterior part of internal margin and apex medium brown connected to a single vein that divides the external part of FW as a lateral field; secondary veins well visible, medium brown; internal margins touching each other only at anterior half, slightly overlapping ( Fig. 10View FIGURE 10 C); glandular thickening absent. Metanotal gland present, with a cluster of bristles and two short projections with rounded top ( Figs. 10View FIGURE 10 F, G).

Legs. FI and FII yellowish brown, annulated with medium brown. TI and TII yellowish brown annulated with medium brown; TI with two same-sized apical spurs; TII with two inner apical spurs and one outer, smaller. FIII yellowish brown, with medium brown maculae on inferior portion, and three bands of several thin, diagonal, medium brown stripes on outer face, apical third medium brown, annulated ( Fig. 10View FIGURE 10 D). TIII medium to dark brown, the apical third yellowish brown; subapical spurs 4 / 4, with serrulation between and above subapical spurs; apical spurs 3 / 3, more developed on inner face; inner apical spurs: dorsal one longer (iad), median shorter than dorsal (iam), ventral smallest (iav) (iad>iam>iav); outer apical spurs: median one longer (oam), dorsal (oad) and ventral (oav) almost same-sized (oam>oad>oav).
