Type material. Holotype male from 18º 10’ 00.00” S 52º 45’ 00.00” W, Parque Nacional das Emas, Mineiros, Goiás, Brazil, ii.1999, F. Rodrigues leg. (IBSP 108072). Paratype: BRAZIL. Goiás: Mineiros, Parque Nacional da Emas, 18º 10’ 00.00” S 52º 45’ 00.00” W, 1♂, ii.1999, F. Rodrigues leg. (IBSP 108072).
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 A–C), A. pusillus (Fig. 118 A–C) and A. bocaina (Fig. 124 A–C) the PA continuous to PAc. They resemble males of all species of the group crassipes, except A. laventana (Fig. 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 A–C), by the serrated area distal to the PAc, continuous to proximal area of PAc. They resemble males of A. dubiomaculatus (Fig. 112 A–C) and A. paranensis by the serrated area being parallel to PAc extension (Fig. 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); two blue-purpleish dorsal scuta on abdomen, anterior scutum thinner than porterior scutum (Fig. 119 A).
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). 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). Rastellum protuberant, inverted, digitiform, V-shaped, hirsute, with thorns on border of apex (Fig. 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). 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 A–B). Patellae III and IV with spines on prolaterodorsal face (Fig. 120 A, C). Tibia IV without spines on dorsal surface (Fig. 120 D). 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).
