Etymology. The specific name is a toponymic after Fazenda Bocaina, one of the localities in which paratypes were collected.

Diagnosis. Males of A. bocaina resemble those of A. paranensis ( Fig. 115 View FIGURE 115 A–C), A. pusillus ( Fig. 118 View FIGURE 118 A–C) and A. emas ( Fig. 121 View FIGURE 121 A–C) by PA continuous to PAc. They resemble those of all species of the group crassipes , except A. laventana ( Fig. 129 View FIGURE 129 A–C) and A. paranensis , by BTA placed medially on prolateral tegular surface. They resemble those of all species of group crassipes , except A. crassipes ( Fig. 107 View FIGURE 107 A–C), by the serrated area distal to PAc, continuous to proximal area of PAc. They resemble those of A. crassipes and A. emas by the lateral swelling above PA ( Fig. 124 View FIGURE 124 A–C). They resemble those of A. paranensis , A. pusillus and A. laventana by the palpal tibia paler than other articles. They resemble those of A. laventana by the presence of smooth roughness on basal labium and maxillae ( Fig. 122 C View FIGURE 122 ). They differ from those of all other species of the group by the quadrate cusps below PAc and along embolus on all views; tegular surface with several cusps imeddiately above embolar base on retrolateral view ( Fig. 124 View FIGURE 124 A–C).

MALE ( CAD 326): Total length 13.87; Carapace, long 5.5; wide 4.37. Carapace rounded. Anterior eye row slightly procurved, posterior row recurved ( Fig. 122 B View FIGURE 122 ). With one short bristles between AME-clypeus. With one bristle between ALE–ALP and few weak and short 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. 122 C View FIGURE 122 ). Rastellum protuberant, inverted V-shaped, hirsute, without spines apically ( Fig. 122 View FIGURE 122 E–F). Smooth roughness on basal labium and maxillae ( Fig. 122 C View FIGURE 122 ). Chelicerae with 15 denticles along prolateral row of teeth. Prolateral row with six megateeth and one basal teeth. Retrolateral row with six megateeth and one denticle between the second distal and third distal megateeth and to denticles between three basala ( Fig. 122 D View FIGURE 122 ). Patella and tibia III with distal crown of well-developed thorns, not interrupted in middle ( Fig. 123 View FIGURE 123 A–B). Patellae III and IV with spines on prolaterodorsal face ( Fig. 123 A, C View FIGURE 123 ). Tibia IV without spines on dorsal surface ( Fig. 123 D View FIGURE 123 ). Ventral pseudoscopulae occupying 40% of tarsus I, 60% 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 yellow; Abdomen pale brown ( Fig. 122 A View FIGURE 122 ).
