Etymology. The specific name, a Latin adjective meaning confounded, was inspired by the type locality name, Serra das Confusıes, which stands for Confusion Mountains.

Diagnosis. Males of A. confusus resemble those of A. jaboticatubas ( Fig. 41 View FIGURE 41 A–C) by the serrated area distal to PAc ( Fig. 44 View FIGURE 44 A–C); PA developed and continuous to PAc ( Fig. 44 A, C View FIGURE 44 ); thin embolus and BTA placed medially on prolateral tegular surface ( Fig. 44 A View FIGURE 44 ). Males differ from those of A. pinhao ( Fig. 32 View FIGURE 32 A–C) and A. jaboticatubas ( Fig. 41 View FIGURE 41 A–C) by the long PS on dorsal view ( Fig. 44 B View FIGURE 44 ) and from all other species of the group pinhao by the short keels prolateral view and tegular region with keels, with a basal swelling above PAc in prolateral view ( Fig. 44 A View FIGURE 44 ).

MALE (CHNUFPI 234): Total length 19.37; Carapace, long 7.25; wide 7.25. Carapace rounded. Anterior eye row slightly procurved, posterior row recurved ( Fig. 42 B View FIGURE 42 ). Without bristles between AMEclypeus. With one short bristle between ALE–ALP and without bristles between posterior eyes-fovea and lateral eyes-edge of carapace. Sternum with eight sigilla fused medially, two distal sigilla more fused than others ( Fig. 42 C View FIGURE 42 ). Rastellum protuberant, inverted V-shaped, hirsute, without spines apically ( Fig. 42 View FIGURE 42 E–F). Chelicerae with 14 denticles along prolateral row of teeth. Prolateral row with six megateeth. Retrolateral row with six megateeth and one denticle in middle of row ( Fig. 42 D View FIGURE 42 ). 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. 43 View FIGURE 43 A–B). Patellae III and IV with spines on prolaterodorsal face ( Fig. 43 A, C View FIGURE 43 ). Tibia IV without spines on dorsal surface ( Fig. 43 D View FIGURE 43 ). Ventral pseudoscopulae occupying 50% of tarsus I, 70% of II and 100% of III and IV. Pseudoscopula of tarsi I and II with setae spaced, forming diffuse group of bristles; on tarsi III and IV, compact. Carapace, chelicerae, sternum, coxae, trochantera, femora, patellae, tibiae, metatarsi and tarsi reddish brown; tibia of palp yellowish-brown, paler than other articles.
