Distribution. Brazil, state of São Paulo.

Diagnosis. This species can be distinguished from other Eidmanacris  by the following characters: frons with maculae dark brown below antennal scape in frontal view; antenomeres medium brown with whitish bands composed of c.a. 5 antenomeres, intersected by a single, whitish antenomere; lateral-posterior projections of Supra-anal plate greyish; superior, supero-internal and infero-internal projections of apex of pseudepiphallic arm reduced to a spine, inferior projection hook-shaped, with bristles on inner surface, upcurved, ventral projection curved inwards with bristles; posterior half of dorsal projection of ectophallic invagination thinner than anterior, posterior margin straight.

Redescription. Head. Medium to reddish brown. Occiput pilose, with central maculae light brown, band light brown going from occiput to margin of each eye; vertex medium brown with three vertical lines light brown in dorsal view ( Fig. 27CView FIGURE 27). Fastigium medium to dark brown, with two rows of bristles, slightly longer than wide, narrowed toward apex, separated from vertex by line forming “v” ( Fig. 27CView FIGURE 27). Frons light brown, with three bands dark brown, vertical, two below eyes, one above clypeus; maculae dark brown below antennal scape, in frontal view ( Figs. 27A, BView FIGURE 27). Three ocelli present, well developed, forming isosceles triangle, central one flattened at bottom, lateral ones elliptical ( Figs. 27A, B, CView FIGURE 27). Eyes with an unpigmented small area on supero-internal angle ( Fig. 27CView FIGURE 27). Maxillary palpi, long, thin, pilose, medium brown, distal portion of joints whitish; joints 3, 4 and 5 almost same-sized ( Fig. 27GView FIGURE 27); apex of joint 5 upcurved. Gena light brown, posterior margin dark brown, line dark brown, vertical, connecting to inferior margin of eye in lateral view ( Fig. 27BView FIGURE 27). Frontoclypeal suture dark yellow, clypeus light brown with central band dark brown in upper margin, in frontal view; labrum whitish, lower portion light brown. Mandible light brown, with inner margin dark brown. Antennal scape light brown, inner margin dark brown ( Fig. 27AView FIGURE 27); antenomeres medium brown with whitish bands composed of c.a. 5 antenomeres, intersected by one antenomere whitish.

Thorax. Pronotum DD reddish brown, wider than long, with sparse dark spots and maculae, slightly pubescent, inflated, divided by very tiny light brown sagittal line ( Fig. 27CView FIGURE 27); DD cephalic margin slightly concave, caudal margin sub straight ( Fig. 27CView FIGURE 27); lateral lobes dark brown, ventro-cephalic angle rounded, lighter than DD, ventrocaudal margin gradually ascendant ( Fig. 27BView FIGURE 27).

Legs. FI and II yellowish brown, annulated with dark brown. TI and II yellowish brown, TI with two samesized apical spurs; TII with two inner apical spurs, one outer, smaller. FIII yellowish brown, with thin stripes medium to dark brown on outer surface, dorsal margin and apical third dark brown ( Fig. 27FView FIGURE 27). TIII yellowish brown; subapical spurs 4/4, with serrulation above and between subapical spurs; apical spurs 3/3, more developed on inner surface: median (iam) longer than dorsal (iad), ventral smallest (iav) (iam>iad>iav); outer apical spurs: median one longer (oam), dorsal sub-equal in length (oad), ventral smaller (oav) (oam>oad>oav). Basitarsi I, II and III dark yellow.

Abdomen. Cylindrical in dorsal view, medium to dark brown, with spots and maculae, divided by a light brown thin sagittal line ( Fig. 27DView FIGURE 27).

Male. Large-sized body, general coloration reddish brown, with dark spots and maculae. FWs medium to dark brown, elongate, triangular, inner margin medium brown; posterior part of inner margin and apex whitish, connected to single vein that divides external part of FW as lateral field, glandular thickening present distally ( Fig. 27CView FIGURE 27); inner margins not touching each other, covering metanotal gland, surpassing metanotum posterior border ( Figs. 27B, CView FIGURE 27). Metanotal gland present, anteromedian crest forming inverted triangle with cluster of bristles; lateral projections short, conical, parallel ( Figs. 27H, IView FIGURE 27), posterior portion of metanotum pubescent.
