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).

MALE (UFMG 5389): Total length 18.12; Carapace, long 8.62; wide 8.12. Carapace anterior part tapering. Anterior eye row slightly procurved, posterior row recurved (Fig. 45 B). With few short bristles between AME-clypeus. With few short and weak bristles between ALE-ALP and between posterior eyes-fovea and lateral eyes-edge of carapace. Sternum with eight sigilla fused medially (Fig. 45 C). Rastellum protuberant, inverted Vshaped, hirsute, without spines apically (Fig. 45 E–F). Chelicerae with 23 denticles along prolateral row of teeth. Prolateral row with five megateeth. Retrolateral row with five megateeth and two denticles between the three basal megateeth (Fig. 45 D). Patella and tibia III with distal crown of well-developed thorns, on patella III interrupted in middle and on tibia III not interrupted in middle (Fig. 46 A–B). Patellae III and IV with spines on prolaterodorsal face (Fig. 46 A–C). Tibia IV without spines on dorsal surface (Fig. 46 D).
