Specimens preserved in ethanol 80%. Distribution. Brazil , state of São Paulo . Diagnosis. This species can be distinguished from other Eidmanacris by the following characters: antenomeres medium brown, with whitish band composed of about 5 antenomeres, increasing in number toward tip of antenna; posterior portion of metanotum very pubescent; anterior half of basitarsi light brown, posterior half dark brown; lateral-posterior projections of Supra-anal plate longer than posterior margin; inferior projection of apex of pseudepiphallic arm hook-shaped, curved inwards. Redescription. Head. Medium to dark brown. Occiput with central maculae light brown, light brown band going from occiput to margin of each eye; vertex medium to dark brown, with three light brown longitudinal lines, in dorsal view ( Fig. 9C ). Fastigium medium to dark brown, with two rows of bristles, slightly longer than wide, narrowed toward apex, separated from vertex by line forming a “V” ( Fig. 9C ). Frons light brown, with three dark brown longitudinal bands, two below eyes and antennal scape and another above clypeus ( Figs. 9A, B ). Three ocelli present, well developed, forming isosceles triangle, central one flattened at bottom, lateral one elliptical ( Figs. 9A, B, C ). Eyes with unpigmented small area on supero-internal angle ( Fig. 9C ). Maxillary palpi long and thin, slightly pilose, medium brown, distal portion of joints white; joints 3, 4 and 5 almost same-sized ( Fig. 9H ); apex of joint 5 upcurved. Gena light brown, posterior margin medium to dark brown in lateral view ( Fig. 9B ). Frontoclypeal suture yellowish brown to pale yellow; clypeus light brown, with dark brown central band in upper margin, in frontal view; labrum whitish, lower portion light brown. Mandible light brown, inner margin dark brown. Antennal scape light brown, inner margin dark brown ( Fig. 9A ); antenomeres medium brown with whitish band composed of c.a. 5 antenomeres, increasing in number toward the end of antennae. Thorax. Pronotum DD wider than long, dark brown, with sparse dark spots and maculae, slightly pubescent, inflated, divided by very tiny light brown sagittal line ( Fig. 9C ); DD cephalic margin slightly concave, caudal margin sub straight ( Fig. 9C ); ventro-cephalic angle rounded, lighter than DD, ventro-caudal margin gradually ascendant ( Fig. 9B ). Legs. FI and II yellowish brown to light yellow, annulated with dark brown. TI and II yellowish brown, TI with two same-sized apical spurs; TII with two inner apical spurs and one outer, smaller. FIII yellowish brown, with medium brown thin stripes on outer surface, apical third medium brown ( Fig. 9D ). 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 anterior half light brown, posterior half medium to dark brown. Abdomen. Fusiform in dorsal view, medium to dark brown, divided by light brown sagittal line. FIGURE 9.
