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

Diagnosis. The male of A. jaboticatubas resembles those of A. pinhao ( Fig. 32 View FIGURE 32 A–C), A. hirsutus ( Fig. 38 View FIGURE 38 A–C), A. ducke ( Fig. 35 View FIGURE 35 A–C) and A. confusus ( Fig. 44 View FIGURE 44 A–C) by serrated area distal to PAc ( Fig. 41 View FIGURE 41 A–C); PA continuous to PAc ( Fig. 41 A View FIGURE 41 ), except in A. hirsutus . The male resembles those of A. pinhao , A. hirsutus and A. ducke by wider tegulum; with robust BTA, placed medially in relation to a middle longitudinal line ( Fig. 41 View FIGURE 41 A–C). They differ from those of A. pinhao ( Fig. 31 View FIGURE 31 A–D) and A. hirsutus ( Fig. 37 View FIGURE 37 A–D) by legs with few bristles, as in most part of the species of genus. The male differs from those of all other species of group by a combination of a wider tegulum with embolus thinner and delicate; PI bigger than other keels and bending over the PAc; and many cusps on retrolateral surface below embolar bases ( Fig. 41 C View FIGURE 41 ).

MALE (IBSP 113186): Total length 18.62; Carapace, long 7.37; wide 7.37. Carapace rounded. Anterior eye row slightly procurved, posterior row recurved ( Fig. 39 B View FIGURE 39 ). Without bristles between AME-clypeus. Without bristles between ALE–ALP and some short and weak bristles between posterior eyes-fovea and lateral eyesedge of carapace. Sternum with eight sigilla fused medially, two distal sigilla more fused than others ( Fig. 39 C View FIGURE 39 ). Rastellum protuberant, inverted V-shaped, hirsute, without spines apically ( Fig. 39 View FIGURE 39 E–F). Chelicerae with 15 denticles widespread along prolateral row of teeth. Prolateral row with six spaced megateeth. Retrolateral row with six megateeth and two denticles between the three basal megateeth ( Fig. 39 D View FIGURE 39 ). Patella and tibia III with distal crown of well-developed thorns, not interrupted in middle ( Fig. 40 View FIGURE 40 A–B). Patellae III and IV with spines on prolaterodorsal face ( Fig. 40 A, C View FIGURE 40 ). Tibia IV without spines on dorsal surface ( Fig. 40 D View FIGURE 40 ). Ventral pseudoscopulae occupying 70% of tarsus I, 80% 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 and tibiae reddish-brown; metatarsi and tarsi paler than other articles; tibia of palp yellow, paler than other articles; abdomen pale brown ( Fig. 39 A View FIGURE 39 ).
