Type locality. Brazil, Rio de Janeiro State, Rio das Ostras municipality, distrito de Rocha Leão.
Type material. Holotype, allotype, 9 males paratypes, 3 female paratypes (MZSP); 2 male and 2 female paratypes (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. Non-type material: 14 juveniles.
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 PsP2; dorsal projections of ectophallic invagination (D.P.Ec.) short, sclerotized, clearly separated.

Dorsum pubescent, light to medium brown, with medium and dark brown maculae and spots (Fig. 7 C); Occiput light brown, with a medium brown band going from the occiput to the margin of each eye (Fig. 7 C); vertex medium to light brown, with dark small maculae; central yellowish line descending towards the fastigium absent (Figs. 7 A, C). Fastigium dark brown, light brown anteriorly, with a thick dark brown midline and two row of bristles (Fig. 7 C); longer than wide, slightly narrowed toward the apex, and narrower than scape, not separated from vertex by a transversal line forming a “v” (Fig. 7 C). Frons light brown, with a large, central yellowish to medium brown area (Fig. 7 A). Three large ocelli present (Figs. 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. (Fig. 7 C). Maxillary palpi medium brown, long, thin, specially the joints 3 to 5(Fig. 7 H); joints 3, 4 and 5 almost same-sized (Fig. 7 H); apical third of joint 5 curved, medium brown, apex whitish. 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 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 B). Frontoclypeal suture yellowish brown, medium brown in the center (Fig. 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 A). Mandible light brown, with internal margins dark brown. Antennal scape light brown, dark brown on inner face (Figs. 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 C); DD cephalic and caudal margins sub-straight (Fig. 7 C); LL ventro-cephalic angle slightly rounded, ventro-caudal margin gradually ascendant (Fig. 7 B). Male FWs medium brown, short, rounded, margins light brown (Fig. 7 C); covering metanotal gland area but not surpassing the metanotum (Figs. 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 C); glandular thickening absent. Metanotal gland present, but without cluster of bristles, composed of two short projections with rounded top (Figs. 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 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). Basitarsus I, II and III yellowish brown.
Abdomen. Sub-cylindrical, dark brown, pubescent, marbled, divided by a pale yellow thick sagittal line. Supra anal plate whitish, pubescent, with light brown maculae in the center; anterior margin slightly concave, lateral ones constricted on median portion, and extended distal projections; posterior margin straight (Fig. 7 I).
