Actinopus excavatus Ríos-Tamayo & Goloboff, 2018: 76 , fig. 39 A–H, 40A–D, 46 (holotype ♂, [32º 16’ S 64º 37’ W], Calamuchita, Córdoba, Argentina, iii–iv.1958, Viana leg., MACN-Ar 36629; paratype ♀, [30º 06’ S 63º 55’ W], Cerro Colorado, Córdoba, Argentina, 20.ix.1959, March leg. MACN-Ar 19830, not examined); World Spider Catalog, 2020.

Diagnosis. According to Ríos-Tamayo & Goloboff (2018), males of A. excavatus can be distinguished from those of A. goloboffi by the thinner and slender bulb ( Ríos-Tamayo & Goloboff, 2018, fig. 39 E–G) and from those of A. balcarce by the poorly developed BTA, well-developed PA. Females present small subquadrate spermathecae with a small external apical lobe (Ríos-Tamayo & Goloboff, 2018, fig. 40 C).

Description. See Ríos-Tamayo & Goloboff (2018: 76).
