Etymology. The specific name is a noun in apposition from the name of a natural reserve at Campus da Pampulha, Universidade Federal de Minas Gerais, from where most of the specimens described below were collected.

Diagnosis. Males of A. pampulha   resemble those of A. candango   ( Fig. 54 View FIGURE 54 A–C) and A. cornelli   ( Fig. 62 View FIGURE 62 A–C) by the wide tegulum and by the short, flattened embolus. They also share with A. paraitinga   ( Fig. 59 View FIGURE 59 A–C) an extension of the embolar serrated area with many cusps below the embolar base, visible in retrolateral view. Males differ from those of all other species of the group pinhao   by an elongated PI, which course reflects the PAc course, along entire length of embolus on dorsal surface ( Fig. 49 View FIGURE 49 A–C). Females differ from those of other species of the group by the presence of two or three similarly elongated lobes on each receptacle ( Fig. 49 D View FIGURE 49 ).

Sternum with eight sigilla fused medially ( Fig. 45 C View FIGURE 45 ). Rastellum protuberant, inverted Vshaped, hirsute, without spines apically ( Fig. 45 View FIGURE 45 E–F).
