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 View FIGURE 72 A–C), A. itaqui ( Fig. 91 View FIGURE 91 A–C), A. mesa ( Fig. 97 View FIGURE 97 A–C) and A. caxiuana ( Fig. 100 View FIGURE 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 View FIGURE 67 A–C), A. rufipes , A. itaqui , A. caxiuana and A. utinga ( Fig. 103 View FIGURE 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 View FIGURE 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 View FIGURE 88 A–C). Females resemble those of A. itapitocai ( Fig. 83 D View FIGURE 83 ) 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 View FIGURE 88 )
