Actinopus ariasi Ríos-Tamayo & Goloboff, 2018

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.

Description. See Ríos-Tamayo & Goloboff (2018: 31).

Distribution. ARGENTINA: Formosa.
