Etymology. The specific name is a noun in apposition from the type locality name, Ipióca, Maceió and a famous strong drink called “ypióca” from the same region of Brazil.

Diagnosis: Males of A. ipioca resemble those of A. caxiuana , A. nattereri and A. itaqui by the palpal tibia being paler than other articles and those of A. rufipes ( Fig. 72 A–C), A. itaqui ( Fig. 91 A–C), A. mesa ( Fig. 97 A–C) and A. caxiuana ( Fig. 100 A–C) by the BTA placed medially on prolateral tegular surface; and those of A. rufipes , A. mesa and A. caxiuana by the developed PA, contiguous to PAc in prolateral view; they resemble those of A. nattereri ( Fig. 67 A–C), A. rufipes , A. itaqui , A. caxiuana and A. utinga ( Fig. 103 A–C) by the palpal tibia being paler than other articles; and differ from those of A. nattereri , A. vilhena , A. harveyi ( Fig. 78 A–C), A. mesa and A. utinga by the inconspicuous serrated area, represented by few cusps, and from all species of the group by the rounded tegulum, as seen on dorsal view; PI sinuous in prolateral view; tegulum with a swelling above PA, visible on prolateral and retrolateral views; and surface of embolus lowest than surface of tegulum on retrolateral view ( Fig. 88 A–C). Females resemble those of A. itapitocai ( Fig. 83 D) by the bilobed receptacles, with outer lobe higher than inner lobe, but males differ from those of the pore distribution reaching 75% of each receptacle apices, and by the bulbous receptacles ( Fig. 88 D)
