Actinopus paranensis Mello-Leitão, 1920: 58 (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 A–C), A. emas (Fig. 121 A–C) and A. bocaina (Fig. 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 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 A–B).
MALE (Holotype, MNRJ 000002): 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). Without bristles between AME-clypeus. Rastellum protuberant, inverted V-shaped, hirsute, without spines apically (Fig. 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). 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 A–B). Patellae III and IV with spines on prolaterodorsal face (Fig. 114 A, C). Ventral scopula absent on tarsi I and II and occupying 100% of III and IV. Carapace, chelicerae, sternum, coxae, trochantera, femora, patellae tibiae reddish brown; metatarsi and tarsi yellowish brown and abdomen pale brown (Fig. 113 A).
