Etymology. The specific name is a substantive honoring the candangos, the name given to the workers who constructed the city of Brasília, the type locality.

Diagnosis. Males of A. candango resemble those of A. pampulha ( Fig. 49 View FIGURE 49 A–C) and A. cornelli ( Fig. 62 View FIGURE 62 A–C) by the wide tegulum and by the short, flattened embolus. Share with A. cornelli the keel arrangement, which are equidistant. Males differ from those of all other species of the group pinhao by the delicate, small serrated area, present but inconspicuous; keels elongated on prolateral surface, almost reaching the base of PA ( Fig. 54 View FIGURE 54 A–C). Females differ from those of other species of the group by the absence of lobes on receptacles, with irregular edges; lateral swollen absent ( Fig. 54 D View FIGURE 54 ).

MALE (MZSP 22109): Total length 17.38; Carapace, long 6.12; wide 5.62. Carapace rounded. Anterior eye row slightly procurved, posterior row recurved ( Fig. 50 B View FIGURE 50 ). Only with marks of intersections of bristles on these interdistances: between AME-clypeus, between ALE–ALP and between posterior eyes-fovea and lateral eyes-edge of carapace. Sternum with eight sigilla fused medially ( Fig. 50 C View FIGURE 50 ). Rastellum inconspicuous, inverted V-shaped, hirsute, without spines apically ( Fig. 50 View FIGURE 50 E–F). Chelicerae with eight denticles along prolateral row of teeth. Prolateral row with five megateeth. Retrolateral row with five megateeth ( Fig. 50 D View FIGURE 50 ). Patella and tibia III with distal crown of well-developed thorns, not interrupted in middle ( Fig. 51 View FIGURE 51 A–B). Patellae III and IV with spines on prolaterodorsal face ( Fig. 51 A, C View FIGURE 51 ). Tibia IV without spines on dorsal surface ( Fig. 51 D View FIGURE 51 ).
