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 A–C) and A. cornelli ( Fig. 62 A–C) by the wide tegulum and by the short, flattened embolus. They also share with A. paraitinga ( Fig. 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 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 ).

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