Type material. Holotype male, allotype and 1 female paratype (MZSP). Holotype male and allotype labeled: “ Gruta G. VOZINHA, Dianópolis, TO, Brasil, 04–09.xii.2007, Andrade et al. col.”. 1 female paratype labeled: “ Gruta Onça, Dianópolis, Tocantins, Brasil, 04–09.xii.2007, Andrade et al. col.”. Specimens preserved in ethanol 80%.
Type locality. Brazil, state of Tocantins, municipality of Dianópolis.
Etymology. From Latin, scopul means “a small broom”, referring to the bristles of the metanotal gland.
Diagnosis. This species can be distinguished from other species of Eidmanacris by the following characters: two light brown, thin lines surrounding median ocellus; antennae dark brown, interspersed with whitish bands composed of three antenomeres, except the first band, composed of only one; pronotum posterior third dark brown; metanotal gland centrally inflated in lateral view, with two horizontal lines of long bristles, one directed anteriorly and the other posteriorly; abdominal tergites II and III with two dark spots; apex of pseudepiphallic arm with ventro-posterior hook, upcurved, with a curved line in lateral view; inner margin of PsP2 concave in dorsal view, apex pointed in lateral view; copulatory papilla thin in lateral view.
Description. Head. Medium brown. Occiput light to medium brown with band dark brown going from occiput to margin of each eye; vertex medium brown, with central line light brown, vertical, until fastigium (Fig. 40C). Band dark brown, lateral, from occiput to clypeus passing through eye in lateral view. Fastigium medium to dark brown, almost without bristles, longer than wide, separated from vertex by transverse furrow forming “v”, two lines light brown, thin, surrounding median ocellus (Fig. 40C). Frons light to medium brown, with central band dark brown, vertical (Fig. 40A). Three ocelli present, well developed, lateral ones rounded, central flattened at bottom (Figs. 40A, B, C). Eyes with unpigmented small area on supero-inner angle (Fig. 40C). Maxillary palpi light brown, long and thin, distal portion of joints whitish; joints 3, 4 and 5 almost same-sized (Fig. 40G); apex of joint 5 upcurved. Gena light brown, posterior margin with stripe dark brown in lateral view (Figs. 40A, B). Frontoclypeal suture dark yellow. Clypeus whitish, with two vertical bands dark brown; labrum whitish, lower portion light brown. Mandible light brown, inner and lower margins dark brown. Antennal scape light to medium brown, inner surface darker with row of bristles (Figs. 40A, B, C); antennae dark brown interspersed by whitish bands composed of three antenomeres, excepting the first band, with only one.
Thorax. Pronotum DD medium brown, posterior third dark brown, wider than long, inflated, divided by line dark brown, thin, vertical; cephalic margin slightly concave, caudal margin almost straight (Fig. 40C); ventrocephalic angle rounded, ventro-caudal margin dark brown, gradually ascendant (Fig. 40B).
Legs. FI and II yellowish brown, annulated with dark brown. TI and II light to medium brown, annulated with medium to dark brown; TI with two same-sized apical spurs, TII with two inner apical spurs, one outer, smaller. FIII yellowish brown, with several stripes medium brown, thin, on outer surface, apical third dark brown (Fig. 40F). TIII dark yellow, apical third lighter; sub apical spurs 4/4, with serrulation above and between subapical spurs; apical spurs 3/3, more developed on inner surface; inner apical spurs: median longer (iam), dorsal somewhat shorter (iad), ventral smallest (iav) (iam>iad>iav); outer apical spurs: median one longer (oam), dorsal (oad) little longer than ventral (oav) (oam>oad>oav). Basitarsi I, II and III yellow.
Abdomen. Sub-cylindrical, medium brown, posteriorly dark, posterior tergites narrower in dorsal view, divided by sagittal line light brown, with dark brown punctuations, tergites II and III with two dark maculae each (Fig. 40D).
Male. Large-sized body, general coloration in different shades of brown. FWs dark brown, inner and posterior margin medium brown, relatively long, triangular, glandular thickening absent, apex connected to single vertical vein that divides external part of FW as lateral field (Figs. 40B, C); inner margins not touching each other, covering metanotal gland area, posterior margin surpassing metanotum (Fig. 40C). Metanotal gland present, anteromedian crest triangular, reduced; apparently lateral projections absent, central region somewhat inflated in lateral view, with two horizontal lines of long bristles, one directed anteriorly, other one posteriorly (Figs. 40H, I). Supra-anal plate dark brown, centrally light brown, anterior margin sub-straight, posterior margin somewhat concave; lateraldistal projection very long like in E. alboannulata, apex light brown with long setae (Fig. 40J). Subgenital plate longer than wide, light brown, with anterior maculae dark brown, anterior margin sub straight, posterior margin concave with invagination almost forming “v” (Fig. 40K).
Phallic complex (Figs. 41A–C; 42A–C). Pseudepiphallus: base of pseudepiphallic sclerite depressed on median part; pseudepiphallic arms sclerotized, upcurved, hard; apex with bristles on outer surface, superior and internal projections reduced, spine-like; inferior projection hook-shaped, upcurved, with line of bristles on curvature in lateral view; dorsal border of apex of pseudepiphallic arm sub-concave; lateral projection short, tip pointed in lateral view; anterior projection of pseudepiphallic sclerite short, anteriorly pointed, not surpassing median part of pseudepiphallus in dorsal view; PsP2 short, curved inwards, well sclerotized, inner margin concave in dorsal view, apex pointed in lateral view, with membranous sphere on inner surface, not surpassing posterior extremity of pseudepiphallic arms; sclerite A anteriorly curved inwards and articulated with PsP 2 in dorsal view; PsP1 short, wider than long, inclined in ventral view, inner surface more sclerotized than outer; elongate and upcurved in lateral view. Ectophallic invagination: Ectophallic apodeme somewhat long, weakly sclerotized, anteriorly robust, dorso-ventrally flattened in lateral view; ectophallic arc short, located below base of pseudepiphallic sclerite in dorsal and ventral views; dorsal projection elongate, well sclerotized, fused, posterior border concave, not surpassing PsP2 posteriorly in dorsal view; ventro-posterior projection elongate, apical third curved inwards. Endophallus: median-posterior projection of endophallic sclerite elongate, not surpassing PsP2 apex; lateral-posterior lobes of endophallic sclerite somewhat short; endophallic apodeme well developed, somewhat long, upcurved in lateral view, limits not surpassing ectophallic apodeme.
Female. Larger than male, general coloration medium brown (Fig. 40E). Supra-anal plate yellowish brown, posterior margin medium to dark brown, somewhat rounded with long bristles (Fig. 40L). Subgenital plate yellowish brown, lateral and posterior borders dark brown, posterior margin with central concavity (Fig. 40M). Ovipositor as in figs. 40N and 40O.
Copulatory papilla (Figs. 42D–F). Little longer than wide, dorso-ventrally thin in lateral view, posterior margin rounded in dorsal and ventral views.
