All specimens preserved in ethanol 80%.
Distribution. Brazil, state of Minas Gerais.
Diagnosis. This species can be distinguished from other Eidmanacris by the following characters: first 40 antenomeres dark brown, followed by whitish antenomeres; pseudepiphallic arm with a line of bristles on outer surface; apex of pseudepiphallic arm clavate; superior, inferior and internal projections reduced; PsP2 rounded outside, concave inside, with small spine pointed anteriorly in ventral view; dorsal projections of ectophallic invagination wide posteriorly, posterior margin concave; posterior apex of ectophallic fold surpassing apex of pseudepiphallic arms; copulatory papilla dorso-ventrally flattened, anterior third little wider in dorsal and ventral views, anterior border whitish.
Redescription. Head. Medium to light brown. Occiput light to medium brown, with maculae yellowish brown, band medium brown going from occiput to margin of each eye ( Fig. 30C View FIGURE 30 ); vertex with three almost no discernible lines vertical, light brown. Fastigium medium to dark brown, longer than wide, slightly narrowed at apex, narrower than scape; separated from vertex by straight line forming “v” ( Fig. 30C View FIGURE 30 ). Frons light to medium brown, with two lateral, dark bands below eyes ( Figs. 30A, C View FIGURE 30 ). Three ocelli present, well developed, lateral elliptical, central flattened at bottom ( Figs. 30A, B, C View FIGURE 30 ); eyes with unpigmented area on supero-internal angle ( Fig. 30C View FIGURE 30 ). Maxillary palpi light brown, joints 3 and 4 medium brown, very long, thin, joints 3–5 almost same-sized ( Fig. 30G View FIGURE 30 ), apex of joint 5 whitish, up-curved. Gena light brown ( Figs. 30A, B View FIGURE 30 ). Frontoclypeal suture medium brown, centrally dark. Clypeus whitish with central maculae light brown; labrum whitish, lower portion light brown. Mandible dark yellow, inner and lower margins dark. Antennal scape yellowish brown, inner surface dark brown ( Figs. 30A, B, C View FIGURE 30 ); about first 40 antenomeres dark brown, followed by whitish antenomeres.
Thorax. Pronotum DD medium brown, anterior third dark, wider than long, inflated, with sparse dark spots and maculae, divided by thin, light yellow sagittal line; DD cephalic margin slightly concave, caudal margin almost straight ( Fig. 30C View FIGURE 30 ); ventro cephalic angle rounded, margin light to medium brown, ventro caudal margin darker, gradually ascendant ( Fig. 30B View FIGURE 30 ).
Legs. FI and II yellowish, annulated with dark brown. TI and II light yellow, annulated with dark brown; TI with two same-sized apical spurs, TII with two inner apical spurs, one outer, smaller. FIII yellowish brown, several thin stripes medium brown on outer surface, apical third dark brown ( Fig. 30F View FIGURE 30 ). TIII medium to dark brown, apical third lighter; 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 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, elongated.
Abdomen. Sub-cylindrical, medium brown, marbled, divided by thin sagittal line light brown ( Fig. 30D View FIGURE 30 ).
Male. Large-sized body, general coloration medium brown, marbled. FWs medium brown, inner margin light brown, less sclerotized, rounded, apex connected to single vein medium brown that divides external part of FW as lateral field, posterior margin with tiny glandular thickening ( Figs. 30B, C View FIGURE 30 ); inner margins not touching each other; FWs covering metanotal gland area, posterior margin not surpassing posterior metanotum border ( Fig. 30C View FIGURE 30 ). Metanotal gland present, with anteromedian crest triangular, line of bristles vertically divided pointing out; lateral projections cylindrical, short, top rounded, near each other; posteriorly, long bristles pointing anteriorly ( Figs. 30H, I View FIGURE 30 ). Supra-anal plate dark brown, anterior margin slightly concave, posterior margin sub-straight; lateral-distal projection very short, similar E. larvaeformis , posteriorly with long setae ( Fig. 30J View FIGURE 30 ). Subgenital plate light brown, lateral borders dark, longer than wide, anterior margin sub straight, posterior margin somewhat rounded ( Fig. 30K View FIGURE 30 ).
Phallic complex ( Figs. 31A–C View FIGURE 31 ; 32A–C). Pseudepiphallus: base of pseudepiphallic sclerite weakly sclerotized, median part narrow; pseudepiphallic arms more sclerotized than base of pseudepiphallic sclerite, slender like in E. meridionalis , upcurved, slightly curved inwards in dorsal and ventral views, outer surface with line of bristles; apex of pseudepiphallic arm clavate; superior, internal and inferior projections very reduced; anterior projection of pseudepiphallic sclerite long and thin, anteriorly pointed in lateral view, surpassing base of pseudepiphallic sclerite; PsP2 well sclerotized, elongate, not surpassing posterior extremity of pseudepiphallic arms, curved inwards, rounded outwards, concave, with membranous sphere in the concavity; small spine anteriorly pointed in ventral view; articulated with sclerite A laterally; PsP1 short, wider than long in ventral view, pointed posteriorly in ventral view, inner surface well sclerotized. Ectophallic invagination: Ectophallic apodeme elongate, slightly upcurved, laterally flattened; ectophallic arc short, located posteriorly to base of pseudepiphallic sclerite; dorsal projection weakly sclerotized, elongate, curved inwards, reaching apex of PsP 2 in dorsal view; ventro-posterior projection sclerotized, not so elongate, curved outwards in ventral view. Endophallus: median-posterior projection of pseudepiphallic sclerite elongate, surpassing pseudepiphallic arms apex, apex wide in ventral view; lateralposterior lobes of endophallic sclerite somewhat short; endophallic apodeme elongate, upcurved in lateral view, anterior limit almost reaching ectophallic apodeme anterior margin.
Female. Larger than male, general coloration medium brown, marbled ( Fig. 30E View FIGURE 30 ). Supra-anal plate medium to dark brown, posterior lateral margins darker, posterior margin rounded with bristles ( Fig. 30L View FIGURE 30 ). Subgenital plate light brown, posterior margin concave, with small central concavity ( Fig. 30M View FIGURE 30 ). Ovipositor as in figs. 30N and 30O.
Copulatory papilla ( Figs 32D–F View FIGURE 32 ). Dorso-ventrally flattened, longer than wide, anterior third little wider in dorsal and ventral views, posterior margin concave, anterior borders unpigmented.
Remarks. This species was described based on a single female. Females of Eidmanacris do not provide as many informative characters for species delimitation as males do. Thus, with the description of the male we can properly re-define the species, and transfer it to Eidmanacris . This species has all the characters that are used in the diagnosis of Eidmanacris . The specimens described here were compared with the holotype, through photographs available in the Orthoptera Species File ( Cigliano et al., 2017).
