Other material examined. Total: 1 male and 3 females, labeled: “ Santa Teresa, ES, Brasil, Estação Biológica Santa Lúcia, 19°57’56.0’’S 40°32’26.4’’W, 16–28.xi.2015, Redü, D.R. leg.” ( IBUSP) . 8 females labeled: “ Brasil, ES, Sta. Teresa, Reserva Sta. Lúcia, i-96, F. A.G. Mello—S. S. Nihei, leg ” ( UBTU). Specimens preserved in ethanol 80%.

Distribution. Brazil, state of Espírito Santo.

Diagnosis. This species can be distinguished from other Eidmanacris by the following characters: antenomeres dark brown on anterior half, whitish on posterior half; caudal margin of pronotum light brown, contrasting with DD; lateral-distal projections of Supra-anal plate parallel; apex of pseudepiphallic arm with superior projection pointed, posterior surface rounded in lateral view, small bristles anteriorly, internal projection with c.a. 5–7 small spines, inferior projection with c.a. 2–3small spines.

Redescription. Head. Reddish brown. Occiput reddish brown with central band light brown going from occiput to vertex, other two laterally, shorter; vertex reddish brown ( Fig. 18C ). Fastigium blackish, with two lines of bristles, longer than wide, separated from vertex by a line forming “v” ( Fig. 18C ). Frons light brown, central band dark brown, vertical, two below eyes ( Fig. 18A ). Three ocelli present, well developed, rounded ( Figs. 18A, B, C ). Eyes with unpigmented small area on supero-internal angle ( Fig. 18C ). Maxillary palpi medium brown, long, thin; joints 3 and 4 almost same-sized; joint 5 the longest ( Fig. 18G ), apex upcurved. Gena light brown, posterior margin with dark brown stripe in lateral view ( Figs. 18A, B ). Frontoclypeal suture dark yellow. Clypeus whitish, with two dark brown vertical bands; labrum whitish, lower portion light brown. Mandible light brown, inner margin dark brown. Antennal scape light brown, inner surface dark brown with row of bristles ( Figs. 18A, B, C ); antenomeres anterior half dark brown, posterior half whitish.

Thorax. Pronotum DD redidish brown, marbled, posterior margin light brown, wider than long, inflated, divided by thin vertical line; DD cephalic margin slightly concave, caudal margin almost straight. ( Fig. 18C ); ventro-cephalic angle light brown, rounded, ventro-caudal margin gradually ascendant ( Fig. 18B ).

Legs. FI and II yellowish brown, annulated with dark brown. TI and II yellowish brown, annulated with medium to dark brown; TI with two same-sized apical spurs, TII with two inner apical spurs and one outer, smaller. FIII yellowish brown, several thin stripes medium brown on outer surface, apical third reddish brown ( Fig. 18F ). TIII yellowish brown, annulated medium brown; 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>oa v). Basitarsi I, II and III yellowish.

Abdomen. Medium brown, sub-cylindrical, divided by sagittal, light brown line, posterior margin of tergite I with spots light brown ( Fig. 18D ).

Male. Large-sized body, general coloration in different shades of brown, with spots and macules. FWs medium brown, sub triangular, glandular thickening on inner and posterior borders, with bristles, inner and posterior margin yellowish brown; apex connected to single vertical vein that divides external part of FW as lateral field ( Figs. 18B, C ); inner margins not touching each other; FWs covering metanotal gland area, posterior margin surpassing metanotum ( Fig. 18C ). Metanotal gland present, anteromedian crest triangular with line of bristles; lateral projections short, top rounded; long bristles posteriorly on metanotum ( Figs. 18H, I ). Supra-anal plate light to medium brown, anterior margin sub-straight, posterior margin somewhat concave with long setae; lateral-distal projections short and parallel ( Fig. 18J ). Subgenital plate longer than wide, medium brown, median maculae greyish, anterior margin sub straight, posterior margin concave with invagination almost forming “v” ( Fig. 18K ). Phallic complex ( Figs. 19A–C ; 20A–C). Pseudepiphallus: base of pseudepiphallic sclerite not depressed; pseudepiphallic arms sclerotized, upcurved; apex of pseudepiphallic arm with bristles on outer surface, superior projection pointed, posterior surface rounded in lateral view, small bristles anteriorly, supero-internal projection with c.a. 5–7 small spines, inferior projection with c.a. 2–3 small spines; anterior projection of pseudepiphallic sclerite long, rounded, not surpassing apex of ectophallic apodeme, in dorsal view; PsP2 elongate, sub-straight, inclined outwards, well sclerotized, apex pointed in lateral view, with membranous sphere on inner surface, not surpassing posterior extremity of pseudepiphallic arms; sclerite A slightly sinuous, articulation visible with PsP 2 in dorsal view; PsP1 short, wider than long, posteriorly pointed in ventral view, posterior surface sclerotized; upcurved in lateral view. Ectophallic invagination: Ectophallic apodeme long, weakly sclerotized, laterally flattened in dorsal view, slightly upcurved in lateral view ectophallic arc short, located anteriorly to base of pseudepiphallic sclerite in dorsal and ventral views; dorsal projection short, slightly sclerotized; ventro-posterior projection elongate, apical third curved outwards.
