It can be easily distinguished by the smaller size and the black, metallic integuments, ( A. atra sp. nov. is black, but not metallic; A. povilaensis sp. nov. is yellowish; A. transversa sp. nov. is reddish). Genitalia are also clearly distinguishable ( Figs 8C, G , 9E , 10A , 11B, F, L, P ). Median lobe of aedeagus ( Fig. 8G ) in ventral view laterally parallel; apex subtriangular, slightly rounded, with generally elongate median tooth; ventral surface with a shallow median depression at apical third; in lateral view median lobe clearly and regularly curved in basal ¾s and straight in apical ¼; dorsal ligula short – from apical third to apical part of median lobe of aedeagus –, wide, apically thinner. Spermatheca ( Fig. 11F ) with pyriform basal part; collum moderately elongate, about twice as long as apical part; ductus elongate, thickset, apically inserted.
