Actinopus ariasi Ríos-Tamayo & Goloboff, 2018: 31, fig. 12 A–G, 44 (holotype ♂, [26º 10’ S 58º 56’ W], Reserva “El Bagual”, Formosa, Argentina, xi.2001 – ii.2002, G. Scrocchi leg., MACN-Ar 36628; not examined); World Spider Catalog, 2020.

Diagnosis. Males of A. ariasi (Ríos-Tamayo & Goloboff, 2018, fig. 13 D–F) resemble those of A. itacolomi (Fig. 153 A–C), A. longipalpis (Fig. 156 A–C), A. cordobensis (Ríos-Tamayo & Goloboff, 2018, fig. 15 D–F) and A. coylei (Ríos-Tamayo & Goloboff, 2018, fig. 16 D–F), by the PA continuous to PAc. They differ from those of A. itacolomi, A. longipalpis and and A. pindapoy by slender bulb and from those of A. cordobensis and A. coylei by the absence of serrated area on the embolar base.
