Type locality. Brazil, Espirito Santo State, Santa Teresa municipality, Reserva Santa Lúcia.

Type material. Holotype, allotype, 3 male paratypes, 3 female paratypes ( MZSP); 1 male, 1 female paratypes (Departamento de Zoologia, Instituto de Biociências, Universidade Estadual Paulista, Botucatu). Brazil, Espírito Santo State, Santa Teresa municipality, Reserva Santa Lúcia, i- 1996, F. A. G. Mello & S. S. Nihei leg. All specimens preserved in alcohol 80 %.

Material Examined. Holotype, allotype, paratypes. Non-type material: 1 juvenile.

Etymology. Named after Dr. Nelson Papavero, one of the greatest entomologists and systematists from Brazil.

Diagnosis. Within the genus, E. papaveroi   n. sp. can be recognized by the following characters: male FWs medium to dark brown, short, triangular, covering metanotal gland area but not surpassing the metanotum; internal margins touching each other at anterior half, the apex separated. Metanotal gland absent, presence of two dark brown rounded depressions in the metanotal gland area. Pseudepiphallic arms sclerotized, short (not surpassing the PsP 2), hard, straight, apex up-curved; apex of pseudepilhallic arm simple (non-bifid), with very small bristles, jagged; ectophallic arc located posteriorly to the median part of pseudepiphallus; dorsal projections of ectophallic invagination (D.P.Ec.) sclerotized, clearly separated, elongated, and curved inwards, reaching the PsP 2.

Male. General coloration medium brown, marbled with dark spots and maculae. Head. Dorsum pubescent, in several shades of brown, with medium and dark brown maculae and spots ( Fig. 4 View FIGURE 4 C); Occiput yellowish, with medium brown maculae, and a dark brown band going from the occiput to the margin of each eye ( Fig. 4 View FIGURE 4 C); vertex medium to light brown, with dark small spots, and a small, central yellowish line descending towards the fastigium ( Figs. 4 View FIGURE 4 A, C). Fastigium medium brown, with two row of bristles; longer than wide, slightly narrowed toward the apex, and narrower than scape ( Fig. 4 View FIGURE 4 C) separated from vertex by a transversal line forming a “v” ( Fig. 4 View FIGURE 4 C). Frons light brown, with a large, central dark brown stripe ( Fig. 4 View FIGURE 4 A). Three large circular ocelli present ( Figs. 4 View FIGURE 4 A, C); eyes with an unpigmented small area on supero-internal angle ( Fig. 4 View FIGURE 4 C). Maxillary palpi light brown, long, thin, specially the joints 3 to 5, distal portion whitish ( Fig. 4 View FIGURE 4 H); joints 3, 4 and 5 almost same-sized ( Fig. 4 View FIGURE 4 H); apical third of joint 5 curved, medium brown, apex whitish. In frontal view, gena dark brown, and a pair of a very thin diagonal light brown stripes ( Fig. 4 View FIGURE 4 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. 4 View FIGURE 4 B). Frontoclypeal suture light brown, dark brown in the center ( Fig. 4 View FIGURE 4 A); upper portion of clypeus whitish, with a central semi-circular medium brown band, lower portion whitish; labrum whitish, lower portion greyish ( Fig. 4 View FIGURE 4 A). Mandible light brown, with internal margins dark brown. Antennal scape light brown, dark brown on inner face ( Figs. 4 View FIGURE 4 A –D); antenomeres medium brown with unpigmented isolated antenomeres.

Thorax. Pronotum DD as long as wide, medium to dark brown, with sparse dark spots and maculae, slightly pubescent, divided by medium brown sagittal line ( Fig. 4 View FIGURE 4 C); DD cephalic margin slightly concave and caudal margin sub-straight ( Fig. 4 View FIGURE 4 C); LL ventro-cephalic angle rounded, ventro-caudal margin gradually ascendant ( Fig. 4 View FIGURE 4 B). Male FWs medium to dark brown, shorter than E. bernardii   n. sp., E. simoesi   n. sp., and E. eliethae   n. sp., triangular, covering metanotal gland area but not surpassing the metanotum ( Figs. 4 View FIGURE 4 B, C); posterior part of internal margin and apex whitish connected to a single vein that divides the external part of FW as a lateral field; internal margins touching each other at anterior half, the apex separated ( Fig. 4 View FIGURE 4 C); glandular thickening present distally. Presence of two dark brown rounded depressions in the metanotal gland area; metanotal gland, including the bristles and projections, absent ( Figs. 4 View FIGURE 4 F, G).

Legs. FI and FII dark yellow, annulated with dark brown. TI and TII dark yellow annulated with medium brown; TI with two same-sized apical spurs; TII with two inner apical spurs and one outer, smaller. FIII light brown, with medium brown thin stripes on outer face, dorsal part and apical third medium brown ( Fig. 4 View FIGURE 4 D). TIII medium 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 hardly visible pale yellow 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 very short distal projections; posterior margin centrally convex, resembling an open “w” ( Fig. 4 View FIGURE 4 I).
