Type locality. Brazil, Rio de Janeiro State, Rio das Ostras municipality, distrito de Rocha Leão.
Type material. Holotype, allotype, 2 males paratypes (MZSP); 1 male paratype (Departamento de Zoologia, Instituto de Biociências, Universidade Estadual Paulista, Botucatu). Brasil, Rio de Janeiro, Rio das Ostras, distrito de Rocha Leão, 22 Km from Casemiro de Abreu, i-1996, F. A. G. Mello & S. S. Nihei leg. All specimens preserved in alcohol 80%.
Material Examined. Holotype, allotype, paratypes.
Etymology. Named after Dra. Elieth F. S. Cruz, retired professor and herpetologist from the Department of Zoology at Instituto de Biociências, Universidade Estadual Paulista (UNESP, Botucatu campus).
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 PsP2; dorsal projections of ectophallic invagination (D.P.Ec.) short, sclerotized, clearly separated.

Fastigium dark brown, with two row of bristles (Fig. 10 C); longer than wide, slightly narrowed toward the apex, and narrower than scape, separated from vertex by a thick transversal line forming a “v” (Fig. 10 C). Frons reddish to medium brown, with a large, central yellowish to dark brown area (Fig. 10 A). Three large ocelli present (Figs. 10 A, C); eyes with an unpigmented area on supero-internal angle (Fig. 10 C). Maxillary palpi medium brown, long, thin, specially the joints 3 to 5(Fig. 10 H); joints 3, 4 and 5 almost same-sized (Fig. 10 H); apical third of joint 5 curved, medium brown, apex whitish. In frontal view, gena dark brown, and a pair of a well visible diagonal medium brown stripe (Fig. 10 A); in lateral view, gena light brown, divided by a diagonal dark brown stripe that goes to the posterior part, and ascends toward the top of head, with several thick dark stripes (Fig. 10 B). Frontoclypeal suture yellowish brown (Fig. 10 A); upper portion of clypeus dark brown, with a pair of light brown maculae, lower portion greysh; labrum greyish (Fig. 10 A). Mandible light brown, with internal margins dark brown. Antennal scape light brown, dark brown on inner face (Figs. 10 A,C); antenomeres medium brown, the anterior portion of the antenna with single shite antenomeres and posterior portion with large unpigmented bands, composed by over 30 antenomeres.
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. 10 C); DD cephalic margin sub-straight, caudal margin slightly concave (Fig. 10 C); ventro-cephalic angle slightly rounded, ventrocaudal margin gradually ascendant (Fig. 10 B). Male FWs dark brown, short, but longer than in E. simoesi n. sp., rounded, margins light brown (Fig. 10 C); covering metanotal gland area and surpassing the metanotum (Figs. 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. 10 C); glandular thickening absent. Metanotal gland present, with a cluster of bristles and two short projections with rounded top (Figs. 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. 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). Basitarsus I, II and III yellowish brown.
Abdomen. Sub-cylindrical, dark brown, pubescent, marbled, divided by a thick pale yellow thick sagittal line. Supra anal plate light brown, medium brown in the center and the distal projections, pubescent (Fig. 10 I); anterior margin sub-straight, lateral ones constricted on median portion, and extended distal projections; posterior margin straight (Fig. 10 I). Subgenital plate longer than wide, pubescent, light brown in the center and medium brown at the borders; anterior margin slightly concave; posterior margin with short, rounded distal projections (Fig. 10 K).
