Actinopus paranensis Mello-Leitão, 1920: 58 View in CoL (holotype ♂, Paraná, Brazil, MNRJ 000002, examined); Bücherl, Timotheo & Lucas, 1971: 121, figs 3–4; World Spider Catalog, 2020.

Diagnosis. The male resembles males of A. pusillus ( Fig. 118 View FIGURE 118 A–C), A. emas ( Fig. 121 View FIGURE 121 A–C) and A. bocaina ( Fig. 124 View FIGURE 124 A–C) by the PA being continuous to the PAc. They resemble those of all species of the group crassipes , except A. crassipes , by the serrated area distal to PAc and continuous to proximal area of PAc ( Fig. 115 View FIGURE 115 A–C). It resembles those of A. pusillus and A. gerschiapelliarum by the palpal tibia, and tarsi paler than other articles. It resembles males of A. bocaina and A. laventana by the palpal tibia paler than other articles. It differs from males of all other species of the group by the absence of BTA ( Fig. 115 View FIGURE 115 A–B).

MALE (Holotype, MNRJ 000002 View Materials ): Total length 12.75; Carapace , long 6.25; wide 5.75. Carapace anterior part tapering, subquadrate. Eyes. Anterior row slightly procurved, posterior row recurved ( Fig. 113 B View FIGURE 113 ). Without bristles between AME-clypeus. Rastellum protuberant, inverted V-shaped, hirsute, without spines apically ( Fig. 113 View FIGURE 113 E–F). Chelicerae with denticles along prolateral row of teeth. Prolateral row with megateeth and teeth between megateeth. Retrolateral row with megateeth and one tooth between second and third basal megateeth ( Fig. 113 D View FIGURE 113 ). Patella and tibia III with distal crown of well developed thorns, interrupted in middle on patella III and not interrupted in middle on tibia III ( Fig. 114 View FIGURE 114 A–B). Patellae III and IV with spines on prolaterodorsal face ( Fig. 114 A, C View FIGURE 114 ). Ventral scopula absent on tarsi I and II and occupying 100% of III and IV.
