Diagnosis. Males of A. tarsalis differ from those of all species, except A. castelo (Fig. 12 A–C), by the copulatory bulb without BTA and by the robust embolar base, inserted basally at a right angle (90°); the embolar apex is flattened and expanded, arrow-shaped in dorsal view. They differ from those of A. castelo by PAc inconspicuous at prolateral surface, embolus shorter, tegulum wider than in A. castelo and PA more conspicuous (Fig. 9 A–C, see Miglio et al., 2012, figs 1–12).
