Type material. Holotype ( MZSP). Brasil, Goiás, Usina Elétrica de Serra da Mesa, Left margin of river Bagagem, 14 °01’S 48 ° 18 ’W, ix- 1995, G. Skuk leg. Specimen preserved in alcohol 80 %.

Etymology. Species named after Dr. Nelson Bernardi, retired professor from the Department of Zoology at Instituto de Biociências, Universidade Estadual Paulista ( UNESP, Botucatu campus), who introduced Silvio Nihei to the systematics discipline.

Diagnosis. Within the genus, E. bernardii   n. sp. can be recognized by the following characters: male FWs triangular, medium to dark brown, covering metanotal gland, the posterior margin surpassing the posterior margin of metanotum; internal margins clearly separated, apart from each other; glandular thickening present distally. Metanotal gland present, composed of cluster of bristles and two round-topped very short projections. Dorsal projection of the apex of pseudepiphallic arms large, rounded, with small bristles; ectophallic arc located anteriorly to the median part of pseudepiphallus; dorsal projections of ectophallic invagination (D.P.Ec.) weakly sclerotized, connected on the median part of the phallic complex, between the basis of PsP 2.

Description

Male. General coloration medium to reddish brown, marbled with dark spots ( Figs. 1 View FIGURE 1 B, C). Head. Dorsum pubescent, in several shades of brown, with dark brown maculae and spots ( Fig. 1 View FIGURE 1 C). Occiput yellowish, with sparse medium brown maculae, and a dark brown band going from the occiput to the margin of each eye ( Fig. 1 View FIGURE 1 C); vertex medium to dark brown, with dark small spots and maculae, and a central yellowish line descending towards the fastigium ( Figs. 1 View FIGURE 1 A, C). Fastigium dark brown, with lateral row of bristles; longer than wide, separated from vertex by a transversal line forming a “v” ( Fig. 1 View FIGURE 1 C). Frons medium to light brown, with a thick central, longitudinal dark brown stripe, with small dark brown spots ( Fig. 1 View FIGURE 1 A). Three large circular ocelli present ( Fig. 1 View FIGURE 1 A, C); eyes with an unpigmented small area on supero-internal angle ( Fig. 1 View FIGURE 1 C). Maxillary palpi medium brown, long, thin, specially the joints 3 to 5, distal portion whitish ( Fig. 1 View FIGURE 1 G); joints 3, 4 and 5 almost same-sized ( Fig. 1 View FIGURE 1 G); apical third of joint 5 curved, medium brown, apex whitish. In frontal view, gena dark brown, and a pair of a small, diagonal light brown stripes ( Fig. 1 View FIGURE 1 A); in lateral view, gena light brown, divided by a diagonal medium brown stripe that goes to the posterior part, and ascends toward the top of head, with several thick dark stripes ( Fig. 1 View FIGURE 1 B). Frontoclypeal suture light brown, dark to medium brown in the center ( Fig. 1 View FIGURE 1 A); upper portion of clypeus whitish, with a central semi-circular medium brown band, lower portion whitish; labrum whitish, lower portion greyish ( Fig. 1 View FIGURE 1 A). Mandible light brown, with internal margins dark brown. Antennal scape light brown, dark brown on inner face ( Figs. 1 View FIGURE 1 A –C); antenomeres medium brown with unpigmented bands of two antenomeres.

Thorax. Pronotum DD reddish brown, wider than long, slightly pubescent, divided by a thin light brown sagittal line ( Fig. 1 View FIGURE 1 C); DD cephalic and caudal margins sub-straight ( Fig 1 View FIGURE 1 C); LL ventro-cephalic angle rounded, ventro-caudal margin gradually ascendant ( Fig. 1 View FIGURE 1 B). Male FWs short, but longer than E. eliethae   n. sp., triangular, medium to dark brown, covering metanotal gland, and posterior margin surpassing the posterior margin of metanotum ( Fig. 1 View FIGURE 1 C); internal margins clearly separated ( Fig. 1 View FIGURE 1 C); glandular thickening present distally; posterior part of internal margin and apex pale yellow connected to single vertical vein that divide external part of FW as a lateral field ( Figs. 1 View FIGURE 1 B, C). Metanotal gland present, composed of cluster of bristles and two very short projections, with top rounded ( Figs. 1 View FIGURE 1 H, I).

Legs. FI and FII yellowish, annulated with dark brown. TI and TII light brown annulated with dark brown; TI with two same-sized apical spurs; TII with two inner apical spurs and one outer, smaller. FIII light brown, with medium brown maculae on inferior portion, and three bands of several thin, medium brown stripes on outer face, apical third medium brown ( Fig. 1 View FIGURE 1 D). TIII medium 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, reddish brown, marbled, divided by a thick, light brown sagittal line. Supra anal plate medium brown, posterior portion light brown, pubescent; anterior margin sub-straight, lateral ones constricted on median portion and extended distal projections; posterior margin straight ( Fig. 1 View FIGURE 1 F). Subgenital plate longer than wide, the central area light brown, anterior margin almost straight; posterior margin with distal projections ( Fig. 1 View FIGURE 1 E).

Male genitalia (2 A –C; 3 A –C). Pseudepiphallus: median part of pseudepiphallus sclerotized, large, central portion with an inverted-u-shaped invagination ( Figs. 2 View FIGURE 2 A, 3 A); pseudepiphallic arms sclerotized, straight, hard; apex bifid, divided in a dorsal and a ventral projection; dorsal projection of the apex large, rounded, with small bristles; ventral projection thin, elongate, pointed, its apex curved inwards ( Figs. 2 View FIGURE 2 A,B; 3 A,B); pseudepiphallic arms laterally flattened, slightly curved, with two tiny spines in the dorsal projection ( Figs. 2 View FIGURE 2 C, 3 C); lateral projection present ( Figs. 2 View FIGURE 2 C, 3 C); ventral projection of pseudepiphallic arms (V.P.Ps.) short, pointed ( Figs. 2 View FIGURE 2 C, 3 C). PsP 2 curved, pointed, with membranous sphere below apex ( Figs. 2 View FIGURE 2 A,B; 3 A,B). PsP 1 short, sclerotized, laterally curved and pointed ( Figs. 2 View FIGURE 2 B, 3 B). Ectophallic invagination: ectophallic apodeme short and robust, weakly sclerotized ( Figs. 2 View FIGURE 2 A, B; 3 A, B); ectophallic arc located anteriorly to the median part of pseudepiphallus ( Figs. 2 View FIGURE 2 A, 3 A); dorsal projections of ectophallic invagination (D.P.Ec.) weakly sclerotized, connected on the median part of the phallic complex, between the basis of PsP 2 ( Figs. 2 View FIGURE 2 A, 3 A); ectophallic fold entirely membranous; in dorsal view, apex of ectophallic fold anterior to PsP 2 and pseudepiphallic arms. Endophallus: latero-posterior projections of the endophallic sclerite very short ( Figs. 2 View FIGURE 2 A; 3 A, B); medio-posterior projection of the endophallic sclerite as for the genus (see Discussion), sclerotized; endophallic apodeme well developed, not surpassing the extremity of the ectophallic apodeme ( Figs. 2 View FIGURE 2 A; 3 A, B).
