Etymology. The specific name is a noun in apposition from the type locality name.

Diagnosis. Males of A. ducke resemble those of A. pinhao ( Fig. 32 View FIGURE 32 A–C), A. hirsutus ( Fig. 38 View FIGURE 38 A–C), A. jaboticatubas ( Fig. 41 View FIGURE 41 A–C) and A. confusus ( Fig. 44 View FIGURE 44 A–C) by the serrated area distal to PAc ( Fig. 32 View FIGURE 32 A–B); PA continuous to PAc ( Fig. 35 View FIGURE 35 A–C), except in A. hirsutus ( Fig. 38 View FIGURE 38 A–C). They resemble A. paranensis ( Fig. 115 View FIGURE 115 A–C), A. hirsutus and A. jaboticatubas by the wider tegulum with robust BTA, placed medially on prolateral tegular surface ( Fig. 35 View FIGURE 35 A–C). Males differ from those of A. pinhao and A. hirsutus by legs with few bristles and from all other species of the group by the presence of slots above PI, on prolateral tegular surface and pigmentation spots above PA on retrolateral view ( Fig. 35 View FIGURE 35 A–C).

MALE (MCN 24987): Total length 19.25; Carapace, long 8.375; wide 7.5. Carapace rounded. Anterior eye row slightly procurved, posterior row recurved almost without interdistance AME–ALE ( Fig. 33 B View FIGURE 33 ). With short bristles between AME-clypeus. With one long bristle between ALE–ALP and many short and weak 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. 33 C View FIGURE 33 ). Rastellum protuberant, inverted V-shaped, hirsute, without spines apically ( Fig. 33 View FIGURE 33 E–F). Chelicerae with six denticles along prolateral row of teeth. Prolateral row with five megateeth. Retrolateral row with five megateeth and two denticles between three basal megateeth ( Fig. 34 D View FIGURE 34 ). Patella and tibia III with distal crown of well-developed thorns, not interrupted in middle ( Fig. 34 View FIGURE 34 A–B). Patella IV with spines on prolaterodorsal face ( Fig. 34 C View FIGURE 34 ). Tibia IV without spines on dorsal surface ( Fig. 34 D View FIGURE 34 ). Ventral pseudoscopulae occupying 20% of tarsus I, 50% 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 paler than other articles; Abdomen pale brown ( Fig. 33A View FIGURE 33 ).
