Actinopus palmar Ríos-Tamayo & Goloboff, 2018: 81 View in CoL View Cited Treatment , fig. 26 A–G, 45 (holotype ♂, [31º 51’ S 58º 19’ W], Parque Nacional “El Palmar”, Entre Ríos, 12–16.ii.1980, P. Grosso and P. Goloboff leg., MACN-Ar 198206, examined); World Spider Catalog, 2020.

Diagnosis. Males of Actinopus palmar differ from those of all other species of the group cucutaensis by the narrow ATP base, copulatory bulb with three prolateral keels in prolaterodorsal view and ATP with a big serrated area ( Fig. 189 View FIGURE 189 A–C). Additionally, they differ from those of all other species of Actinopus , except A. crassipes , A. dubiomaculatus , A. pusillus , A. emas , A. bocaina , A. laventana and A. gerschiapelliarum , by the distal leg articles being paler than proximal leg articles and the palp.

MALE (MACN 19826): Total length 8.62; Carapace, long 4.3; wide 3.6. Carapace anterior part tapering. Eyes. Anterior row slightly procurved, posterior row recurved ( Fig. 187 B View FIGURE 187 ). One bristle between AME-clypeus and also ALE–PLE. Sternum with eight sigilla near center and two distal sigilla very fused to each other ( Fig. 187 C View FIGURE 187 ). Rastellum protuberant, inverted V-shaped, hirsute, with many spines on apex ( Fig. 189 View FIGURE 189 D–E). Chelicerae with denticles along Prolateral row ( Fig. 187 D View FIGURE 187 ). Patella and tibia III with distal crown of well-developed thorns ( Fig. 188 View FIGURE 188 A–B).Patellae III and IV with spines on prolaterodorsal face ( Fig. 188 A, C View FIGURE 188 ). Patella IV without spines dorsally ( Fig. 188 D View FIGURE 188 ). Ventral pseudoscopulae occupying 30% of tarsi I, 50% of II and 100% of III and IV. Pseudoscopula of tarsi I and II with setae spaced, forming diffuse group of bristles; On tarsi III and IV, compact. Carapace and Chelicerae reddish brown, sternum yellowish brown, coxae, trochantera, femora and patellae reddish brown, tibiae, metatarsi and tarsi yellowish brown, abdomen pale gray ( Fig. 187 A View FIGURE 187 ).
