Actinopus reycali Ríos-Tamayo & Goloboff, 2018

Actinopus reycali Ríos-Tamayo & Goloboff, 2018: figs 6 A–G, 7 A–E (holotype ♂, [24º 42’ S 64º 37’ W], Parque Nacional “El Rey”, Salta, Argentina, 10.xi.1976, M. Rumboll leg., MACN-Ar 36518; paratype ♀, same locality of holotype, i.1981, Grosso & P. Goloboff leg., MACN-Ar 36519; not examined); World Spider Catalog, 2020.

Diagnosis. Males of A. reycali (Ríos-Tamayo & Goloboff, 2018, fig. 6 D–F) resemble those of A. harveyi (Fig. 78 A–C), A. itapitocai (Fig. 83 A–C), A. itaqui (Fig. 91 A–C), A. xingu (Fig. 94 A–C), A. caxiuana (Fig. 100 A–C) and A. utinga (Fig. 103 A–C) by the general shape of the copulatory bulb, but males differ from those of the more elongated copulatory bulb. They differ from those of A. utinga by the embolus being thinner and PA continuous to PAc. In the disposition of keels, the copulatory bulb resembles A. rufipes (Fig. 72 A–C), A. harveyi and A. utinga, but males differ from those of PA not continuous to PI. Males resemble those of all other species of the group nattereri, except A. nattereri (Fig. 67 A–C), A. vilhena (Fig. 75 A–C), A. harveyi, A. itapitocai (Fig. 83 A–C), A. xingu and A. utinga by BTA located medially on width of tegulum.

Description. See Ríos-Tamayo & Goloboff (2018: 17).

Actinopus septemtrionalis Ríos-Tamayo & Goloboff, 2018

Actinopus septemtrionalis Ríos-Tamayo & Goloboff, 2018: figs 8 A–I, 9 A–E, 43 (holotype ♂, [26º 36’ S 65º 12’ W], El Cadillal, Tucumán, Argentina, 25.v.1983, P. Goloboff leg., MACN-Ar 36501; paratype ♀, same data as holotype, MACN-Ar 36052; not examined); World Spider Catalog, 2020.

Diagnosis. Males of A. septemtrionalis (Ríos-Tamayo & Goloboff, 2018, fig. 8 G–I) resemble A. clavero (Ríos-Tamayo & Goloboff, 2018, fig. 4 E–G) by the elongated shape of the copulatory bulb, but males differ by the more developed PA, PA continuous to PAc and a wider angle of embolar curvature. Females of A. septemtrionalis (Ríos-Tamayo & Goloboff, 2018, fig. 9 D–E) have unilobate receptacles and differ from those of all other species by having the receptacles much more longer than wide (two or more times).

Description. See Ríos-Tamayo & Goloboff (2018: 21).

Distribution. ARGENTINA: Salta, Tucumán, Catarmarca and Formosa.
