( Figs. 12E–H , 14 , 19B , 20 )

Amanayara sp. B in Sperber (1999)

Etymology. The specific epithet refers to the ex-president of republic of Brazil (11/15/1922 until 11/15/1926), Arthur da Silva Bernardes, born in Viçosa (MG), and founder of the Escola Superior de Agricultura e Veterinária—ESAV, that later came to be know as the Universidade Federal de Viçosa—UFV.

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 show a convex dorsal border ( Fig. 14B ); (ii) ectophallic apodeme extending towards dorsal portion of genitalia, but not crossing the rami ( Fig. 14C ); (iii) rami curved towards genitalia dorsal side ( Fig. 14C ).

Description. Holotype. ♂, measurements (mm): BL 7,43; MID 0,83; LP 1,38; MWP 1,71; MLF 3,92; MLT 2,88. Head dark brown, covered with long black bristles in the 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 partially surrounded, on the superior border, by black one spot, lateral ocelli partially surrounded, on the internal border, by one black spot each; antennal scape enlarged and dark yellow, like the antennal articles; gena dark yellow; clypeus light brown on the superior portion and whitish on the inferior; labrum whitish on the superior portion and light brown on the inferior; mandibles coloration varying from dark yellow on the base to dark brown on the apex; maxillary palpi light yellow with whitish truncate apex. Pronotum dark brown, covered by long black bristles, presence of the fine and short light brown hairs covering all its extension; meso- and metanotum uniformly light yellow on the 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 brown, covered by fine hairs, similar to those on head and pronotum; tergites dark brown, covered by short light brown hairs; cercus dark yellow; supra-anal plate dark yellow; 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; 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 the longest internally, and the median one the longest externally. Male genitalia: Expansion of pseudepiphallic median lobe pointing towards the center of the genitalia ( Fig. 14A ); pseudepiphallic median lobe show a convex dorsal border ( Fig. 14B ); pseudepiphallic sclerite without cleft on the center ( Fig. 14A and 14B ); ectophallic apodeme extending towards dorsal portion of genitalia, but not crossing the rami ( Fig. 14C ); rami curved towards genitalia dorsal side ( Fig. 14C ). Allotype, ♀, measurements (mm): BL 7,52; MID 0,90; LP 1,47; MWP 1,81; MLF 4,38; MLT 2,96; OL 2,50. Body shape very similar to male, showing only the following differences: cercus dark yellow; abdominal sternites softly divided on three vertical bands, varying from light yellow on the center to dark yellow on the border; abdomen dorsally more light that the head and pronotum, showing all tergites dark yellow, with anterior portion varying from light brown on the tergite 1 to dark on the tergites 2–8. Ovipositor with dark yellow band extending from the base to the median region, turning to dark brown on the distal portion ( Figs. 12E–H and 14D ).

Commentaries. Some specimens have a less body size that holotype and allotype, showing head, pronotum and abdomen dark brown with reduced size of genitalia. However the general morphology isn’t different enough for to classify as a new specie, so we consider how intraspecific variations.

Measurements. Males (n=6, excluding holotype). BL 6,29–7,62 (7,00 ± 0,48); MID 0,8–0,83 (0,82 ± 0,02); LP 1,22–1,30 (1,26 ± 0,03); MWP 1,66–1,79 (1,69 ± 0,05); MLF 3,50–3,83 (3,69 ± 0,13); MLT 2,46– 2,83 (2,67 ± 0,12). Females (n=6, excluding allotype). BL 7,05–7,60 (7,44 ± 0,24); MID 0,83 (0,83 ± 0,00); LP 1,32–1,45 (1,38 ± 0,05); MWP 1,40–1,89 (1,83 ± 0,06); MLF 3,92–4,00 (3,93 ± 0,07); MLT 2,75–2,88 (2,83 ± 0,04); OL 2,47–2,63 (2,54 ± 0,06).
