EtYmologY. Named after the Brazilian naturalist and zoological illustrator Dr. Frederico Lencioni Neto.

Diagnosis. Within Eidmanacris , E. lencionii n. sp. can be recognized by the following characters: male FWs short, triangular, yellow towards internal border, reaching the median first abdominal tergite; apex rounded connected to single vertical vein that divide external part of FW as a lateral field; apex of pseudepiphallic arms bifid, with bristles; lateral projection of the pseudepiphallic sclerite absent; ventral projection of pseudepiphallic arms short, curved; ectophallic arc broad, located posteriorly to the median part of pseudepiphallus; dorsal projections of ectophallic invagination short, sclerotized, clearly separated; ectophallic fold entirely membranous, and connected to the dorsal projections of the pseudepiphallic invagination.

Description. Male. Medium sized body, pubescent, general coloration medium brown, slightly marbled ( Fig. 1A View FIGURE 1 ). Head. Dark to medium brown, without maculae. Occiput and vertex medium brown, with yellowish maculae and a thin median line over the epicranial sutures area, with sparse bristles. Fastigium dark brown, mainly on its lateral part, longer than wide, narrower than scape. Three ocelli present, pre-eminent, the median largest ( Figs 1B View FIGURE 1 ); eye with unpigmented area on supero-internal angle ( Fig. 1E View FIGURE 1 ). Maxillary palpi long and thin ( Figs. 1B, D View FIGURE 1 ); joints 1 and 2 whitish, 3rd, 4th and 5th joints medium to light brown at apex ( Fig. 1D View FIGURE 1 ); apex of 5th joint slightly curved, light brown to whitish on distal portin ( Fig. 1D View FIGURE 1 ). In frontal view, frons light brown with a longitudinal medium brown stripe ( Fig. 1B View FIGURE 1 ). Gena light to medium brown; clypeus light brown, the central area medium brown, lower portin whitish ( Fig. 1D View FIGURE 1 ); labrum whitish, the apex light brown ( Fig. 1B View FIGURE 1 ). Antennal scape whitish ( Fig. 1B View FIGURE 1 ); antenomeres medium brown with interspersed light bands. Banding pattern as the figure 1C.

Thorax. Pronotum DD as long as wide, dark brown, slightly pubescent, divided by a thin, light brown vertical line; DD cephalic and caudal margin concave. Male FWs short, triangular, yellowish towards internal border, reaching the first abdominal tergite; apex rounded connected to single vertial vein that divide external part of FW as a lateral field ( Figs. 1F View FIGURE 1 ); internal margins not touch each other in apical half; metanotal structure present, composed of a cluster of bristles and two short lateral projectins ( Fig. 1J View FIGURE 1 , arrows).

Legs. FI and FII yellowish. TI and II dark brown annulated with yellowish brown; TI and II with 2 same-sized apical spurs. FIII light brown with several dark brown stripes and spots on inner face, apical part dark brown; outer face light brown with medium brown maculae and stripes, apical part medium brown; TIII medium brown annulated with light brown; TIII subapical spurs 4/4; serrulatin between and above subapical spurs, except between inner apical dorsal (iad) and fist subapical (is1); apical spurs 3/3, more developed on inner face; inner apical spurs ( Fig. 1G, H View FIGURE 1 ): median one longer (iam), dorsal sub-equal in length (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).

Abdomen. Dark brown, slightly pubescent, divided by longitudinal light yellow line ( Fig. 1A View FIGURE 1 ). Supra anal plate square, medium brown, darkening in the margins; anterior margin straight on median part, lateral margins constricted in median portion ( Fig. 1I View FIGURE 1 ); posterior margin straight with extended distal projections in the latero-distal margin. Subgenital plate triangular, longer than wide, pubescent, dark brown; anterior margin sub-straight; posterior margin with distal projections ( Fig. 1L View FIGURE 1 ).

Phallic complex. Pseudepiphallus sclerotized, curved inwards ( Figure 2A–C View FIGURE 2 ); pseudepiphallic arms sclerotized, straight ( Figs. 2A, B View FIGURE 2 ); apex of pseudepiphallic arms bifid, with bristles ( Fig. 2A View FIGURE 2 ); lateral projection absent; ventral projection of pseudepiphallic arms short, curved ( Fig. 1B View FIGURE 1 ). PsP2 curved and pointed, with membranous sphere ( Fig. 2A View FIGURE 2 ); PsP1 well developed, laterally connected with PsP2 ( Figs. 2B, C View FIGURE 2 ). Ecophallic invagination: ectophallic apodeme long ( Fig. 2A View FIGURE 2 ); ectophallic arc wide, located posteriorly to the median part of pseudepiphallus ( Fig. 2A View FIGURE 2 ); dorsal projections of ectophallic invagination short, sclerotized, clearly separated ( Fig. 2A View FIGURE 2 ); ectophallic fold entirely membranous; in dorsal view, apex located posteriorly to the PsP2 and pseudepiphallic arms, and connected to the dorsal projections of the pseudepiphallic invagination ( Figs. 2A, B View FIGURE 2 ); medio-posterior projection of the endophallic sclerite sclerotized ( Fig. 2B View FIGURE 2 ); endophallic apodeme well developed ( Fig. 2B View FIGURE 2 ).

Female. Larger than male, general coloration darker than male; maxillary palpi also darker than male ( Fig. 1M View FIGURE 1 ); supra anal plate yellowish brown, with anterior margin straight, lateral ones not constricted on median portion, and posterior margin rounded, with thick bristles ( Fig. 1K View FIGURE 1 ); subgenital plate small, posterior margin rounded ( Fig. 1N View FIGURE 1 ); ovipositor yellowish, as long as FIII and TIII ( Table 1).

Distribution. The only record of Eidmanacris in Brazilian caves is for the species E. alboannulata , which type –locality is the cave “Gruta da Toca”, Itirapina municipality, São Paulo State (Mesa & de Mello, 1985). Through identification of material from environmental licensing studies of different lithologies, and bibliography (e.g. Pinto da Rocha (1995)), the distribution of the genus is expanded to the North and Midwest regions of Brazil, reaching latitudes not recorded for Eidmanacris ( Fig. 4 View FIGURE 4 ). The known distribution for E. lencionii n. sp. is the region of Brumadinho municipality, Minas Gerais State. The sampled caves are located at the east border of the Quadrilatero Ferrifero karst area ( Fig. 3).
