Amanayara sp. C in Sperber (1999)

Etymology. The specific epithet refers to my mother, Helena Maria Ribeiro Pereira.

Type. Holotype, ♂, Brasil, MG, Viçosa , “Aeroporto”, 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) Ends of the expansion of pseudepiphallic median lobe pointing towards the apical region of the genitalia ( Fig. 16A and 16B View FIGURE 16 ); (ii) pseudepiphallic parameres extending in direction of genital distal portion ( Fig. 16A View FIGURE 16 ) e (iii) cleft extending on the center of pseudepiphallic sclerite, but not longer and with parallel lateral borders like A. ribasi sp. nov. ( Fig. 16B and 16C View FIGURE 16 ).

Description. Holotype, ♂, measurements (mm): BL 5,52; MID 0,67; LP 1,20; MWP 1,56; MLF 3,33; MLT 2,29. Head dark yellow, covered with long black bristles in the median region; presence of the 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 in the superior border, by one black spot, lateral ocelli with light brown inferior border; antennal scape enlarged and yellowish, like the antennal articles; gena dark yellow; clypeus dark yellow on the superior portion and whitish on the inferior; labrum light yellow on the superior portion and dark yellow on the inferior; mandibles coloration varying from dark yellow on the base, to light brown on the apex; maxillary palpi light yellow with whitish truncate apex. Pronotum dark yellow, covered with long black bristles, presence of the fine and short light brown hair covering all its extension; meso- and metanotum uniformly light yellow, 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 dark yellow, covered by fine hairs similar to those on head and pronotum; tergites light brown, covered by short light brown hairs; cercus light yellow; supra-anal plate light brown; subgenital plate dark yellow on center to light 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; hindtibia 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 is the longest internally, and the median one the longest externally. Male genitalia: Ends of the expansion of pseudepiphallic median lobe pointing towards the apical region of the genitalia ( Fig. 16A and 16B View FIGURE 16 ); cleft present on the center of pseudepiphallic sclerite ( Fig. 16B and 16C View FIGURE 16 ). End of ectophallic apodeme crossing the rami, when in lateral view ( Fig. 16C View FIGURE 16 ). Allotype, ♀, measurements (mm): BL 7,14; MID 0,87; LP 1,50; MWP 1,87; MLF 3,88; MLT 2,92; OL 2,43. Body shape very similar to male, showing only the following differences: meso and metanotum same male coloration, however showing a dark brown border more large on the lateral side of metanotum and anterior portion of mesonoto; ovipositor varying from light yellow on the base to dark brown on the distal portion ( Figs. 15C–D View FIGURE 15 and 16D View FIGURE 16 ).

Commentaries. One specimen showed coloration more dark than the holotype, like A. bernardesi sp. nov. (head dark brown and pronotum dark brown). However the general morphology of genitalia doesn’t show variation.

Measurements. Males (n=8, excluding holotype). BL 5,71–6,86 (6,26 ± 0,42); MID 0,67–0,73 (0,69 ± 0,02); LP 1,17–1,27 (1,19 ± 0,04); MWP 1,45–1,62 (1,51 ± 0,06); MLF 2,96–3,50 (3,21 ± 0,18); MLT 2,21– 2,38 (2,31 ± 0,05). Females (n=4, excluding allotypes). BL 7,14–7,43 (7,17 ± 0,29); MID 0,80–0,83 (0,83 ± 0,02); LP 1,33–1,45 (1,37 ± 0,06); MWP 1,73–1,77 (1,75 ± 0,02); MLF 3,75–3,92 (3,89 ± 0,08); MLT 2,63– 2,79 (2,75 ± 0,07); OL 2,23–2,43 (2,35 ± 0,08).
