Type material. Holotype male, allotype, 5 males paratypes and 4 females paratypes (MZSP); 2 males paratypes and 2 females paratypes ( UBTU). Labeled : “ Gruta Casa de Pedra, Pq. Nacional da Chapada dos Guimarães, Brasil, MT, Chapada dos Guimarães, 15°6’34’’S / 55°35’51’’W, 10–13/xii/2014, L. D. Campos et al. col. ” Specimens preserved in ethanol 80%.

Type locality. Brazil, state of Mato Grosso, municipality of Chapada dos Guimarães.

Etymology. From latin, neo means “new”. Named due to the similar coloration with E. marmorata .

Diagnosis. This species can be distinguished from other Eidmanacris by the following characters: dark brown interspersed with whitish bands, first band with only one antenomere, other bands increasing in the number of antenomeres; apex of pseudepiphallic arm dorsally truncate in lateral view, superior and inferior projections hook shaped, upcurved, supero-internal and inferior projections reduced like spines in dorsal view; PsP2 curved inwards, posterior margin pointed, very sclerotized; dorsal projection of ectophallic invagination well sclerotized, elongate, posterior third thin, posterior margin with small central concavity.

Description. Head. Light brown, marbled, dorsum pubescent, with dark spots. Occiput centrally light brown, laterally dark brown, with band light brown going from occiput to margin of each eye ( Fig. 46C ); vertex light brown, with anterior maculae dark.

In frontal view, frons light brown, with central triangle dark brown, four lateral bands dark brown, two vertical below eyes, two diagonal below scapes ( Fig. 46A ). Three ocelli present, well developed, lateral rounded, central flattened at bottom ( Figs. 46A, B, C ); eyes with unpigmented area on supero-internal angle ( Fig. 46C ).

Legs. FI and II light brown, annulated with dark brown. TI and II light to medium brown, annulated with dark brown; TI with two same-sized apical spurs, TII with two inner apical spurs, one outer, smaller.

Male. Large-sized body, different shades of brown, marbled, with dark spots and maculae. FWs dark brown, relatively long, triangular, apex connected to single vein that divides external part of FW as lateral field, antero-internal margin yellowish brown, postero-internal margin with glandular thickening ( Figs. 46B, C ); inner margins touching each other, covering metanotal gland area, posterior margin reaching posterior metanotum border ( Fig. 46C ). Metanotal gland present, with anteromedian crest triangular, thin line of long bristles on lateral part; lateral projections short, conical, tip rounded; posteriorly with bristles ( Figs. 46H, I ). Supra-anal plate light brown, centrally medium to dark brown, anterior margin sub-straight, posterior margin somewhat concave; antero-lateral borders dark brown, lateral-distal projection medium brown, elongate, with long setae ( Fig. 46J ).
