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

Diagnosis. Males of A. emas resemble those of A. paranensis ( Fig. 115 View FIGURE 115 A–C), A. pusillus ( Fig. 118 View FIGURE 118 A–C) and A. bocaina ( Fig. 124 View FIGURE 124 A–C) the PA continuous to PAc. They resemble males of all species of the group crassipes , except A. laventana ( Fig. 129 View FIGURE 129 A–C) and A. paranensis , by the BTA being placed medially on the prolateral tegular surface.They resemble males of all species of the crassipes group, except A. crassipes ( Fig. 107 View FIGURE 107 A–C), by the serrated area distal to the PAc, continuous to proximal area of PAc. They resemble males of A. dubiomaculatus ( Fig. 112 View FIGURE 112 A–C) and A. paranensis by the serrated area being parallel to PAc extension ( Fig. 121 View FIGURE 121 A–C). They resemble males of A. crassipes by the metatarsi and tarsi being paler than other articles. They differ from those of all other species of the group by PS not visible on dorsal view ( Fig. 121 B View FIGURE 121 ); two blue-purpleish dorsal scuta on abdomen, anterior scutum thinner than porterior scutum ( Fig. 119 A View FIGURE 119 ).

MALE (IBSP 108072): Total length 8; Carapace, long 3.875; wide 3.75. Carapace anterior part tapering and posterior part triangular. Eyes. Anterior eye row slightly procurved, posterior row recurved ( Fig. 119 B View FIGURE 119 ). With few short and weak bristles between AME-clypeus, between ALE–ALP, between posterior eyes-fovea and lateral eyes-edge of carapace. Sternum with eight sigilla fused medially, two distal sigilla more fused than others ( Fig. 119 C View FIGURE 119 ). Rastellum protuberant, inverted, digitiform, V-shaped, hirsute, with thorns on border of apex ( Fig. 119 View FIGURE 119 E–F). Chelicerae with two denticles along prolateral row of teeth. Prolateral row with nine megateeth. Retrolateral row with five megateeth ( Fig. 119 D View FIGURE 119 ). 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. 120 View FIGURE 120 A–B). Patellae III and IV with spines on prolaterodorsal face ( Fig. 120 A, C View FIGURE 120 ). Tibia IV without spines on dorsal surface ( Fig. 120 D View FIGURE 120 ). Ventral scopulae occupying 50% of tarsus I, 70% of II and 100% of III and IV. Scopula of tarsi I and II with setae spaced, forming diffuse group of bristles; On tarsi III and IV, compact, with 10% of metatarsus I and II filled by scopula. Carapace, chelicerae, sternum, coxae, trochantera, femora, patellae, tibiae, metatarsi and tarsi reddish brown; Abdomen pale bluish-brown ( Fig. 119 A View FIGURE 119 ).
