Etymology. Named after Dr. Marcello G. Simões, paleontologist from the Department of Zoology at Instituto de Biociências, Universidade Estadual Paulista ( UNESP, Botucatu campus).

Diagnosis. Within the genus, E. simoesi   n. sp. can be recognized by the following characters: male FWs medium brown, short, rounded, margins light brown; covering metanotal gland area but not surpassing the metanotum. Metanotal gland present, but without cluster of bristles, composed of two short projections with rounded top. Apex of pseudepiphallic arms bifid, divided in two dorsal, and a ventral projection, with bristles; dorsal projections of the apex pointed, 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.

Three large ocelli present ( Figs. 7 View FIGURE 7 A, C); eyes with an unpigmented area on supero-internal angle, this area larger than in E. bernardii   n. sp. and E. papaveroi   n. sp.

In frontal view, gena dark brown, with several small light brown spots, and a pair of a well visible diagonal light brown stripes ( Fig. 7 View FIGURE 7 A); in lateral view, gena light brown, almost 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. 7 View FIGURE 7 B). Frontoclypeal suture yellowish brown, medium brown in the center ( Fig. 7 View FIGURE 7 A); upper portion of clypeus whitish, with a central semi-circular medium brown band, lower portion whitish; labrum whitish, lower portion greyish ( Fig. 7 View FIGURE 7 A). Mandible light brown, with internal margins dark brown. Antennal scape light brown, dark brown on inner face ( Figs. 7 View FIGURE 7 A,C); antenomeres medium brown, the first three unpigmented bands composed by 2– 3 whitish antenomeres, followed by a long whitish band composed by over 30 antenomeres, the remaining medium brown.

Thorax. Pronotum DD wider than long, light to medium brown, with sparse dark spots and maculae, slightly pubescent, divided by a distinct light brown sagittal line, and another four light brown, thick lines ( Fig. 7 View FIGURE 7 C); DD cephalic and caudal margins sub-straight ( Fig. 7 View FIGURE 7 C); LL ventro-cephalic angle slightly rounded, ventro-caudal margin gradually ascendant ( Fig. 7 View FIGURE 7 B). Male FWs medium brown, short, rounded, margins light brown ( Fig. 7 View FIGURE 7 C); covering metanotal gland area but not surpassing the metanotum ( Figs. 7 View FIGURE 7 B, C); posterior part of internal margin and apex light brown connected to a single vein that divides the external part of FW as a lateral field; internal margins touching each other only at anterior third ( Fig. 7 View FIGURE 7 C); glandular thickening absent. Metanotal gland present, but without cluster of bristles, composed of two short projections with rounded top ( Figs. 7 View FIGURE 7 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 ( Fig. 7 View FIGURE 7 D). TIII medium to dark brown, the apical third pale yellow; 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).
