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.

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).
