Amanayara sp. A in Sperber (1999)

Etymology. The specific epithet refers to Walbercy Ribas, marketing and creator of "O grilo feliz" ("The Happy Cricket"). In the story of Walbercy, The Happy Cricket is an inhabitant of the Amazon Forest that differs from the other animals in being wise, protective and a very talented musician.

Type. Holotype, ♂, Brasil, MG, Viçosa , Mata do Paraíso, 24.ii.1996 (Sperber, C.F. leg.).

Diagnosis. This species may be distinguished from the other species of Amanayara by the following combination of characteristics: (i) pseudepiphallic median lobe long, narrow and curved in its distal portion ( Fig. 13A and 13B View FIGURE 13 ); (ii) distal expansion of median lobe as large as long, when in lateral view ( Fig. 13C View FIGURE 13 ); (iii) cleft longer than wide, with parallel lateral borders in the center of the pseudepiphallic sclerite ( Fig. 13B and 13C View FIGURE 13 ); (iv) ectophallic apodeme, when in lateral view, not crossing the rami ( Fig. 13C View FIGURE 13 ).

Description. Holotype. ♂, measurements (mm): BL 7,62; MID 0,83; LP 1,38; MWP 1,85; MLF 4,00; MLT 2,88. Head light to dark brown, covered with long black bristles in median region; presence of fine and short light brown hairs covering all its extension; black eyes occupying more than 50 percent of the head, when in lateral view; three ocelli present, central ocellus surrounded by one black spot, lateral occeli partially surrounded, on their internal border, by one black spot each; antennal scape enlarged and light yellow, like antennal articles; gena dark yellow; clypeus light brown on the superior portion and whitish on the inferior; labrum whitish on superior portion and light brown on inferior; mandibles coloration varying from light yellow on base, to dark brown on apex; maxillary palpi light yellow with whitish truncate apex. Pronotum light brown, covered by long black bristles, presence of fine and short light brown hairs covering all its extension; meso- and metanotum whitish to light yellow on central portion, with dark brown, narrow border, covered by hairs; forewings vestigial, hidden under pronotum; row of long bristles present on anterior and posterior pronotum border. Abdominal sternites light to dark brown, covered by fine hairs, similar to those on head and pronotum; tergites strongly dark brown, covered by short light brown hairs; cercus light yellow; supra-anal plate light brown; subgenital plate light brown on center, to dark brown on lateral border, row of long and fine light brown bristles on its final portion. Fore and middle legs light yellow, covered by fine light brown hairs; femurs and tibiae with long black bristles; fore tibiae with two apical spurs on ventral face, one spur longer than the other; tympanum absent on the fore tibiae; middle tibiae with two apical spurs of the same size. Hind legs with femur light yellow on the inferior side, to dark yellow on superior side; hindtibiae with three dorsal spurs on external face and four dorsal spurs on internal face, being the uppermost and the inferior one glandular; three apical spurs are present on internal and three on external face, being the superior one the longest internally, and the median one the longest externally. Male genitalia: Pseudepiphallic median lobe long, narrow and curved on distal portion ( Fig. 13A and 13B View FIGURE 13 ); distal expansion of median lobe as large as long, when in lateral view ( Fig. 13C View FIGURE 13 ); cleft longer than wide, with parallel lateral borders in the center of the pseudepiphallic sclerite ( Fig. 13B and 13C View FIGURE 13 ); ectophallic apodeme, when in lateral view, not crossing the rami ( Fig. 13C View FIGURE 13 ); rami not curved ( Fig. 13C View FIGURE 13 ). Allotype, ♀, measurements (mm): BL 8,10; MID 1,00; LP 1,43; MWP 1,89; MLF 4,21; MLT 3,04; OL 2,47. Body shape very similar to male, showing only the following differences: abdomen dark brown to black; ovipositor with whitish band extending from the base to the median region, turning to dark brown on the distal portion ( Figs. 12A–D View FIGURE 12 and 13D View FIGURE 13 ).
