Campos et al., col.”. Male paratype labeled: “Bonito, MS, Brasil, x.2002, Pitfall, C.A. Reinis et al. ” Specimens preserved in ethanol 80%.

Type locality. Brazil, state of Mato Grosso do Sul, municipality of Aquidauana. 

Etymology. Named after the French orthopterist, Dr. Laure Desutter-Grandcolas.

Diagnosis. This species can be distinguished from other Eidmanacris  by the following characters: metanotal gland with lateral projections inflated, fused medially; Supra-anal plate with antero-lateral borders reddish; apex of pseudepiphallic arm with superior projection, posterior margin convex with line of bristles dorsally, central invagination forming inferior hook-shaped, upcurved projection; in dorsal view, inner border with internal projection reduced, spine-like; in ventral view, ventral projection short; PsP2 inflated, anteriorly convoluted, ventrally pointed.

Description. Head. Light and dark brown, dorsum pubescent. Occiput dark brown, with light brown band going from occiput to margin of each eye; vertex dark to medium brown, with three light brown lines, vertical, crossed by two horizontal lines in dorsal view. Fastigium dark brown, longer than wide, slightly narrowed toward apex, narrower than scape, with two rows of bristles, separated from vertex by thick transverse line forming “v” ( Fig. 49CView FIGURE 49). Frons light brown, with diagonal band dark brown below eye; centrally two inverted dark brown triangles, one below other, dorsal larger ( Fig. 49AView FIGURE 49). Three ocelli present, well developed, lateral elliptical, central flattened at bottom ( Figs. 49A, B, CView FIGURE 49). Eyes with unpigmented area on supero-internal angle ( Fig. 49CView FIGURE 49). Maxillary palpi joints 1 and 2 whitish, joints 3 to 5 medium brown, long, joint 5 the longest, apex lighter, upcurved ( Fig. 49GView FIGURE 49). Gena light brown, with a band medium brown forming “v” in lateral view ( Fig. 49BView FIGURE 49). Frontoclypeal suture dark yellow. Clypeus whitish with two vertical bands dark brown, central; labrum whitish, lower portion yellowish brown ( Fig. 49AView FIGURE 49). Mandible light brown, inner margin dark brown. Antennal scape light brown, inner surface dark brown with row of bristles ( Figs. 49A, B, CView FIGURE 49); antennae dark brown with white bands of two antenomeres and increasing in number until antennae end, one antenomere white separating bands.

Thorax. Pronotum DD dark brown, posterior border lighter, wider than long, inflated, divided by thin vertical line medium brown; DD cephalic margin slightly concave, caudal margin almost straight ( Fig. 49CView FIGURE 49); ventrocephalic angle lighter, rounded, ventro-caudal margin gradually ascendant ( Fig. 49BView FIGURE 49).

Legs. FI and II light brown, annulated with dark brown. TI and II medium brown, annulated with dark brown; TI with two same-sized apical spurs, TII with two inner apical spurs, one outer, smaller. Basitarsi I and II first half light brown, apical half dark brown. FIII light brown, two dorsal bands of several medium brown thin stripes on outer surface, apical third dark brown ( Fig. 49FView FIGURE 49). TIII anterior surface dark yellow, posterior surface medium brown; subapical spurs 4/4, serrulation above and between subapical spurs; apical spurs 3/3, more developed on inner surface; inner apical spurs: median one longer (iam), dorsal somewhat shorter (iam), ventral smaller (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 anteriorly light yellow, posteriorly medium brown.

Abdomen. Dark brown, marbled and punctuated, slightly pubescent, sub-cylindrical, divided by sagittal line light brown, tergite II with two dark maculae ( Fig. 49DView FIGURE 49).

Male. Large-sized body, general coloration dark brown, marbled. FWs dark brown, relatively long, triangular, apex connected to single vertical vein that divides external part of FW as lateral field, glandular thickening absent, margins medium brown ( Figs. 49B, CView FIGURE 49); inner margins touching each other, covering metanotal gland, surpassing metanotum posterior border ( Fig. 49CView FIGURE 49). Metanotal gland present, with anteromedian crest triangular, reduced, line of bristles pointing posteriorly touching lateral projections; lateral projections yellowish, anterior portion whitish, inflated, upcurved, inner margins touching each other ( Figs. 49H, IView FIGURE 49). Supra-anal plate light brown, antero-lateral borders reddish, anterior margin slightly concave, posterior margin sub-straight, lateral-distal projection greyish, elongate, long bristles on posterior border ( Fig. 49JView FIGURE 49). Subgenital plate longer than wide, light brown, posterior margin dark brown; anterior margin sub straight, posterior margin concave with central invagination rounded in ventral view ( Fig. 49KView FIGURE 49).

Phallic cOmPlex ( Figs. 50A –CView FIGURE 50; 51A –C). Pseudepiphallus: base of pseudepiphallic sclerite centrally thin; pseudepiphallic arms sclerotized, hard, upcurved almost forming 90° angle; apex of pseudepiphallic arm with bristles on outer surface; in lateral view, dorsal margin sub-straight, with superior projection, posterior margin convex with line of bristles dorsally, invagination in central part forming inferior projection hook-shaped, upcurved; in dorsal view, inner border with supero-internal projection reduced, spine-like; in ventral view, ventral projections short (like E. cOrumbatai  , but regressed), curved inwards, apex rounded with hard bristles; lateral projection somewhat long, tip pointed; anterior projection of pseudepiphallic sclerite short, anteriorly rounded, not surpassing base of pseudepiphallic sclerite in lateral and ventral view; PsP2 elongate, sclerotized, inflated, anteriorly convoluted, ventrally pointed in lateral view, with membranous sphere on concavity, not surpassing posterior extremity of pseudepiphallic arms; sclerite A straight, inclined inwards, flattened, visible articulation with PsP2; PsP1 well sclerotized, in lateral view: elongate, upcurved. Ectophallic invagination: ectophallic apodeme somewhat long, robust; ectophallic arc short located anteriorly to base of pseudepiphallic sclerite; dorsal projections elongate, fused, posterior margin concave, not surpassing PsP 2 in dorsal view; ventro-posterior projections elongate, posterior third curved inwards. Endophallus: median-posterior projection of endophallic sclerite elongate, not surpassing PsP2 apex; lateral-posterior lobes of endophallic sclerite long; endophallic apodeme well-developed not surpassing ectophallic apodeme.
