Diagnosis. According to Ríos-Tamayo & Goloboff (2018) , males of Actinopus balcarce differ from those of A. goloboffi ( Ríos, 2014 , figs 6–8) and A. excavatus (Ríos-Tamayo & Goloboff, 2018, fig. 39 E–G) by having BTA well developed, PA porly developed ( Ríos-Tamayo & Goloboff, 2018 , fig. 38 D–F) and by the lower number of retrolateral thorns on tibia II ( Ríos-Tamayo & Goloboff, 2018 , fig. 38 B).

Actinopus excavatus Ríos-Tamayo & Goloboff, 2018 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). FIGURE 196. Actinopus jamari sp. nov. , male: A–F IBSP: A.
