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

Description. Male (holotype). General appearance somewhat similar to that of A. (S.) propinqua sp. nov. ( Figs 135 View Figs 131–142 , 253 View Figs 241–256 ) but with following differences: tegmina clearly narrower ( Fig. 136 View Figs 131–142 ), with dorsal field light brown to yellowish but having transparent region of mirror, and with stridulatory apparatus as in Figs 136 and 137 View Figs 131–142 ; hind wings with venation as in Fig. 138 View Figs 131–142 ; last abdominal tergite shorter (almost as other abdominal tergites in length) but with dorsal part even shorter (its anteromedian edge distinctly concave), posteromedian lobe also very short and curved downwards as well as having barely concave posterior edge and a pair of small (not deep) notches around this lobe ( Figs 147, 149 View Figs 143–155 ); epiproct larger, with almost angular apex and slightly concave median part ( Figs 147, 149 View Figs 143–155 ); cerci with dorsolateral and ventromedial branches somewhat shorter than in A. (S.) propinqua sp. nov. and different in shape (first branch with strong apical lateral hook directed medially, and with acute-angled medial projection clearly shorter than above-mentioned hook; second branch also not curved but almost cup-like, i.e. roundly widened and strongly concave dorsolaterally, and with small apical hook directed more or less laterally; Figs 147–149 View Figs 143–155 ); genital plate with posterolateral lobules somewhat wider and dorsoventrally flattened, and with apical notch having sinuate edges ( Fig. 148 View Figs 143–155 ); genitalia with unpaired and asymmetrical sclerite lacking teeth as well as narrower than in A. (S.) propinqua sp. nov. ( Fig. 150 View Figs 143–155 ).

Female unknown.

Length (mm). Body 21.0; body with wings 37.0; pronotum 5.1; tegmina 32.0; hind femora 18.0.

Comparison. The new species differs from A. (S.) propinqua sp. nov. in the features listed above. From A. (A.) lanceolata and A. (A.) macricula , A. (S.) fruhstorferi sp. nov. is distinguished by the characters given in the key to Abrodiaeta subgenera.
