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 A–C), A. pusillus (Fig. 118 A–C) and A. emas (Fig. 121 A–C) by PA continuous to PAc. They resemble those of all species of the group crassipes, except A. laventana (Fig. 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 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 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). 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 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). 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). Rastellum protuberant, inverted V-shaped, hirsute, without spines apically (Fig. 122 E–F). Smooth roughness on basal labium and maxillae (Fig. 122 C). 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). Patella and tibia III with distal crown of well-developed thorns, not interrupted in middle (Fig. 123 A–B). Patellae III and IV with spines on prolaterodorsal face (Fig. 123 A, C). Tibia IV without spines on dorsal surface (Fig. 123 D). 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).
