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).
