( Figs 139–142 View Figs 131–142 , 151–155 View Figs 143–155 , 254 View Figs 241–256 )

Etymology. This species is named after the Minas Gerais State of Brazil where it was collected.

Type material. Holotype – male, BRAZIL: Minas Gerais State [“ Minas Geraës ”], 1897, “ex coll. Fruhstorfer ”, “104-98”.

Description. Male (holotype). General appearance more or less similar to that of A. (S.) propinqua sp. nov. and A. (S.) fruhstorferi sp. nov. However, following characteristic features developed: body colouration with dense redish dots on pronotum, six short and narrow whitish longitudinal stripes on pronotal disc along its lateral edges, dorsal tegminal field coloured as in A. (S.) fruhstorferi sp. nov., rest tegminal part having yellowish anal border and one row of blackish cells near it as well as blackish line along proximal third of lateral edge of dorsal field; upper tubercle of head rostrum slightly shorter than in these congeners (barely projected before lower tubercle); pronotum slightly lower than in these species and with barely concave anterior half of ventral edge of each lateral lobe ( Fig. 139 View Figs 131–142 ); tegmina almost as in A. (S.) fruhstorferi sp. nov. in shape but with costal area having cellular venation and one longitudinal pseudovein, with RS distinctly longer and having more parallel branches and narrower area between them ( Fig. 140 View Figs 131–142 ), and with stridulatory apparatus as in Figs 140 and 141 View Figs 131–142 ; structure of hind wings as in Fig. 142 View Figs 131–142 ; last abdominal tergite as in A. (S.) propinqua sp. nov. but without any posteromedian lobe ( Fig. 151 View Figs 143–155 ); epiproct located behind this tergite, rather large, almost triangularly oval (with narrowly rounded apex), and directed downwards; cerci somewhat longer, having three branches on each cercus and almost concave medial surface between these three branches (lateral branch longest, curved medially in distal half and having characteristic small dorsal projection near middle of its length; dorsomedial branch spine-like, directed upwards/medially, and located near base of cercus; ventromedial branch shortest, almost finger-like, directed downwards/medially, and located also not far from cercal base; Figs 151–153 View Figs 143–155 , 254 View Figs 241–256 ); genital plate distinctly shorter than in A. (S.) propinqua sp. nov. and A. (S.) fruhstorferi sp. nov. but more or less similar to that of these congeners in general shape ( Figs 152, 153 View Figs 143–155 ); genitalia with unpaired and asymmetrical sclerite very small and lacking teeth ( Figs 154, 155 View Figs 143–155 ).

Female unknown.

Length (mm). Body 20.5; body with wings 38.0; pronotum 4.8; tegmina 29.0; hind femora 19.0.

Comparison. The new species is similar to A. (A.) lanceolata and A. (A.) macricula sp. nov. in the general appearance, long tegminal RS and characteristic structure of Sc branches, but it is distinguished from these species as well as from A. (S.) propinqua sp. nov. and A. (S.) fruhstorferi sp. nov. by the absence of any posteromedian lobe on the male last tergite posterior edge, and from the two latter congeners, by the unpaired sclerite of male genitalia much smaller.
