Diagnosis. For A. nigritus , both sexes have a black head and mesosoma, a reddish orange metasoma, and the setae are black ( Figs. 2 b,c). The clypeus and frons is covered in sparse silver setae in the female, while the male only has silver setae present lateral to the antennal insertions; the clypeus of the male has black setae. Additionally, the female has three comb spines and the last metasomal tergum has stout spines, while the aedeagus of the male is slightly longer than the parapenial lobes and has expanded apical lobes ( Fig. 2 in Evans (1969)).

Distribution. West-central Argentina to Brazil.
