Diagnosis. This species can be recognized by the punctate preepisternum; the dark green integument, mainly on frons; by the presence of a tuberculate projection on S1 of the females; and by the apically narrowed hind leg basitarsus on males, as in A. modica sp.nov. From that species it differs by the rugulose metapostnotum posterior surface and by the imbricate integument among punctures on mesoscutum and scutellum of females.

Distribution. A. tenax sp. nov. is known from Northeastern Brazil, in the states of Bahia, Paraíba and Pernambuco and southwards to Espírito Santo.
