Diagnosis. Males of A. patagonia (Ríos-Tamayo & Goloboff, 2018, fig. 29 A–H) resembles A. osbournei (Fig. 133 C), A. dioi (Fig. 136 C) and all species of group goloboffi (Ríos, 2014, figs 1–12; Ríos-Tamayo & Goloboff, 2018, fig 38 A–G, 39 A–H, 40 A–D) by two basal and two proximal sigilla merged on the middle of portions basal and proximal of sternum. They differ from those of group goloboffi by absence of central depression on the middle of sternum. They resemble those of the two species of group goloboffi (Fig. 135 A–C, Fig. 138 A–C) by the position of BTA on the tegulum and three keels in prolateral view of the tegulum. Differs from A. osbournei and A. dioi by wider embolus and PA developed; differs from A. dioi by elongated shape of the copulatory bulb. The females differs from A. gerschiapelliarum (Ríos-Tamayo & Goloboff, 2018, fig. 19 C–D) by a smaller constriction below external lobes on each receptacle and by presence of pores on all the length of receptacles.
