P. 101, Parque Nacional Iguazú, Misiones, Argentina, 13–15.ix.1992, P. Goloboff & C.

Diagnosis. Males of A. ramirezi (Ríos-Tamayo & Goloboff, 2018, fig. 32 D–F) differ from those of most species of the pinhao group by PA continuous to PI. They resemble those of A. ducke (Fig. 35 A–C), A. hirsutus (Fig. 38 A–C), A. cornelli (Fig. 62 A–C) and A. insignis (Ríos-Tamayo & Goloboff, 2018, fig. 45 B–D) by PA continuous to PAc. They differ from those of A. ducke (Fig. 35 A–C) and A. confusus (Fig. 44 A–C) by BTA placed ventrally on prolateral tegular surface. They resemble those ofs A. pinhao (Fig. 32 A–C) and A. hirsutus (Fig. 37 A–D) by hirsute legs, differing from A. pinhao by the absence of tegular swelling above PA and from A. hirsutus by BTA most pronounced, PA less pronounced and a serrated area developed, extending to the base of the embolus and arranged in three rows. Females differ from those of A. pampulha (Fig. 49 D) and A. candango (Fig. 54 D) by pore distribution reaching only 75% of the receptacles length; and from A. paraitinga by the absence of lateral swelling on receptacles.
