Aussereria insignis Holmberg, 1881: 171, pl. 1, fig. 2 (Holotype ♂, Provincia Bonaerensis, Chacabuco, Zárate, Buenos Aires, Argentina, ZMUC, not examined).

Actinopus insignis: Simon, 1892: 80; Ríos-Tamayo & Goloboff, 2018: 45, fig. 21 A–G; World Spider Catalog, 2020.

Diagnosis. Males of A. insignis resemble those of most species of the group pinhao by PA continuous to Pac and differ from those of A. pinhao (Fig. 32 A–C) by the lateral tegular swelling above PA in prolateral view, from A. paraitinga (Fig. 59 A–C) by serrated area at embolus base, from A. hirsutus (Fig. 38 A–C) and A. pinhao by the hirsute legs, and from A. hirsutus and A. cornelli (Fig. 62 A–C) by the PA continuous to PI. Females differ from those of A. pampulha (Fig. 49 D) and A. candango (Fig. 54 D) by the pore distribution reaching 75–100% of the receptacle length; and from A. paraitinga (Fig. 59 D) by the absence of lateral swellings on the receptacles, which are bilobed, with lateral lobes longer than inner lobes.

Description. See Ríos-Tamayo & Goloboff (2018: 45).

Distribution. ARGENTINA: BuenosAires,Córdoba, and Isla Martín Garcia. URUGUAY: Maldonado.
