Diagnosis. This species can be distinguished from other Eidmanacris by the following characters: antennae medium brown, with isolated whitish antenomeres; lateral-anterior region of DD with dark brown spots; subgenital plate two times longer than wide; male phallic complex singular, very elongated; inferior projection of apex of pseudepiphallic arm truncate in lateral view; ectophallic apodeme c.a. three times longer than pseudepiphallic sclerite; median-posterior projection of endophallic sclerite c.a. four times longer than pseudepiphallic sclerite; endophallic apodeme as long as wide, laterally flattened.
Redescription. Head. Dark brown. Occiput and vertex medium to dark brown, with three vertical lines light brown in dorsal view, band light brown going from occiput to margin of each eye; vertex light to medium brown (Fig. 36C). Fastigium dark brown, apically dark, with two rows of bristles, slightly longer than wide, slightly narrowed toward apex, separated from vertex by a horizontal line light brown (Fig. 36C). Frons light brown, with three vertical bands dark brown, two below eyes, one above clypeus (Figs. 36A, B). Three ocelli present, well developed, rounded, forming isosceles triangle (Figs. 36A, B, C). Eyes without unpigmented small area on superointernal angle (Fig. 36C). Maxillary palpi, long, thin, pilose, light brown, distal portion of joints whitish; joints 3, 4 and 5 almost same-sized (Fig. 36G); apex of joint 5 upcurved. Gena light brown; in lateral view, posterior margin medium to dark brown (Fig. 36B). Frontoclypeal suture dark yellow; clypeus light brown, lateral dark, with medium brown band on upper margin; labrum whitish, lower portion light brown. Mandible dark brown, light brown maculae on lower margin. Antennal scape light brown, internal margin medium brown (Fig. 36A); antennae medium brown, interspersed by some isolated whitish antenomeres.
Thorax. Pronotum DD wider than long, reddish to medium, with sparse dark spots and maculae, pubescent, inflated, divided by a light brown sagittal line, lateral-anterior region with dark brown spots (Fig. 36C); DD cephalic margin sub-straight, caudal margin slightly concave (Fig. 36C); lateral lobes darker than DD, ventrocephalic angle rounded, ventro-caudal margin gradually ascendant (Fig. 36B).
Legs. FI and II yellowish brown, annulated with dark brown. TI and II yellowish brown, annulated with medium brown; TI with two same-sized apical spurs, TII with two inner apical spurs, one outer, smaller. FIII light yellow, with thin stripes outer surface medium brown, apical third dark brown (Fig. 36F). TIII medium brown; sub apical spurs 4/4, with serrulation above and between subapical spurs, base of spines yellowish; apical spurs 3/3, more developed on inner surface: dorsal (iad) longer than median (iam), ventral smallest (iav) (iad>iam>iav); outer apical spurs: dorsal one longer (oad), median smaller (oam), ventral smallest (oav) (oad>oam>oav). Basitarsi I, II and III yellow.
Abdomen. Cylindrical in dorsal view, medium brown, with dark brown spots, divided by light brown median band (Fig. 36D).
Male. Large sized body, general coloration medium to reddish brown, with dark brown spots and maculae. FWs medium brown, very short, not surpassing metanotum anterior border, without visible veins, inner margins not touching each other, metanotal gland absent (Figs. 36B, C). Supra-anal plate light brown, centrally yellowish, slightly pubescent; anterior margin slightly concave, lateral-posterior projections elongate, longer than posterior margin of supra anal plate, with long bristles; posterior margin sub-straight (Fig. 36H). Subgenital plate two times longer than wide, with lateral pubescence, medium brown; anterior margin almost straight, posterior margin rounded (Fig. 36I).
Phallic complex (Figs. 37A, B; 38A–C; 39A–C). Pseudepiphallus: central portion of base of pseudepiphallic sclerite narrow than lateral portions in dorsal view; pseudepiphallic arms sclerotized, hard, slightly upcurved in lateral view; apex of pseudepiphallic arm with few bristles on outer surface, curved inwards forming a 90° angle; superior projection with tiny bristles, inferior projection truncate in lateral view; anterior projection of pseudepiphallic sclerite present, elongate, surpassing base of pseudepiphallic sclerite, apically pointed; PsP2 hardly sclerotized, elongate, thin, not surpassing posterior extremity of pseudepiphallic arms in dorsal view, curved downwards, apex pointed in lateral view, without membranous sphere on inner surface; sclerite A connected with base of pseudepiphallic, straight, visible articulation with PsP2; PsP1 short, posterior margin rounded, inner surface concave in ventral view. Ectophallic invagination: ectophallic apodeme c.a. three times longer than pseudepiphallic sclerite, thin; ectophallic arc located posteriorly base of pseudepiphallic sclerite in dorsal view; dorsal projections not visible; ectophallic fold membranous, apex surpassing pseudepiphallic arms, sub-apical lateral lobes. Endophallus: median-posterior projection c.a. four times longer than pseudepiphallic sclerite; lateralposterior lobes of endophallic sclerite short; endophallic apodeme as long as wide, laterally flattened, surpassing apex of ectophallic apodeme.
Female. Larger than male, general coloration similar (Fig. 36E). Supra-anal plate light brown, anterior margin concave, posterior margin slightly rounded, darker, with bristles (Fig. 36J).
