Type locality. Brazil, Goiás State, “Usina Elétrica de Serra da Mesa, left margin of river Bagagem. 14°01’S, 48°18’W.
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 PsP2.
Description
Male. General coloration medium to reddish brown, marbled with dark spots (Figs. 1 B, C). Head. Dorsum pubescent, in several shades of brown, with dark brown maculae and spots (Fig. 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 C); vertex medium to dark brown, with dark small spots and maculae, and a central yellowish line descending towards the fastigium (Figs. 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 C). Frons medium to light brown, with a thick central, longitudinal dark brown stripe, with small dark brown spots (Fig. 1 A). Three large circular ocelli present (Fig. 1 A, C); eyes with an unpigmented small area on supero-internal angle (Fig. 1 C). Maxillary palpi medium brown, long, thin, specially the joints 3 to 5, distal portion whitish (Fig. 1 G); joints 3, 4 and 5 almost same-sized (Fig. 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 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 B). Frontoclypeal suture light brown, dark to medium brown in the center (Fig. 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 A). Mandible light brown, with internal margins dark brown. Antennal scape light brown, dark brown on inner face (Figs. 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 C); DD cephalic and caudal margins sub-straight (Fig 1 C); LL ventro-cephalic angle rounded, ventro-caudal margin gradually ascendant (Fig. 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 C); internal margins clearly separated (Fig. 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 B, C). Metanotal gland present, composed of cluster of bristles and two very short projections, with top rounded (Figs. 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 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 F). Subgenital plate longer than wide, the central area light brown, anterior margin almost straight; posterior margin with distal projections (Fig. 1 E).
Male genitalia (2A–C; 3A–C). Pseudepiphallus: median part of pseudepiphallus sclerotized, large, central portion with an inverted-u-shaped invagination (Figs. 2 A, 3A); 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 A,B; 3A,B); pseudepiphallic arms laterally flattened, slightly curved, with two tiny spines in the dorsal projection (Figs. 2 C, 3C); lateral projection present (Figs. 2 C, 3C); ventral projection of pseudepiphallic arms (V.P.Ps.) short, pointed (Figs. 2 C, 3C). PsP2 curved, pointed, with membranous sphere below apex (Figs. 2 A,B; 3A,B). PsP1 short, sclerotized, laterally curved and pointed (Figs. 2 B, 3B). Ectophallic invagination: ectophallic apodeme short and robust, weakly sclerotized (Figs. 2 A, B; 3A, B); ectophallic arc located anteriorly to the median part of pseudepiphallus (Figs. 2 A, 3A); dorsal projections of ectophallic invagination (D.P.Ec.) weakly sclerotized, connected on the median part of the phallic complex, between the basis of PsP2 (Figs. 2 A, 3A); ectophallic fold entirely membranous; in dorsal view, apex of ectophallic fold anterior to PsP2 and pseudepiphallic arms. Endophallus: latero-posterior projections of the endophallic sclerite very short (Figs. 2 A; 3A, 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 A; 3A, B).
