Etymology. The specific name is a Latin adjective meaning hairy, referring to the hirsute legs, a very notable and uncommon character in Actinopus .

Diagnosis. Males of A. hirsutus differ from those of all other species of Actinopus , except A. pinhao ( Fig. 31 View FIGURE 31 A–D), by the hirsute legs. They also resemble A. pinhao ( Fig. 32 View FIGURE 32 A–C), A. ducke ( Fig. 35 View FIGURE 35 A–C), A. jaboticatubas ( Fig. 41 View FIGURE 41 A–C) and A. confusus ( Fig. 44 View FIGURE 44 A–C) by the serrated area distal to PAc ( Fig. 38 View FIGURE 38 A–C); they resemble those of A. pinhao , A. ducke and A. jaboticatubas by the wide tegulum with robust BTA, placed medially on the prolateral tegular surface ( Fig. 38 A View FIGURE 38 ). They differ from all other species of the group pinhao by the PA continuous to PI ( Fig. 38 A View FIGURE 38 ).

MALE (MCN): Total length 17.12; Carapace, long 6.87; wide 6.75. Carapace rounded. Anterior eye row slightly procurved, posterior row recurved ( Fig. 36 B View FIGURE 36 ). With many short bristles between AME-clypeus. With one long bristle between ALE–ALP and many short and weak bristles between posterior eyes-fovea and lateral eyes-edge of carapace. Sternum with eight sigilla fused medially, two distal sigilla more fused than others ( Fig. 36 C View FIGURE 36 ). Rastellum protuberant, inverted V-shaped, hirsute, without spines apically ( Fig. 36 View FIGURE 36 E–F). Chelicerae with 14 denticles along Prolateral row and five along retrolateral row of teeth. Prolateral row with five megateeth. Retrolateral row with six megateeth ( Fig. 36 D View FIGURE 36 ). Patella and tibia III with distal crown of well-developed thorns, not interrupted in middle ( Fig. 37 View FIGURE 37 A–B). Patellae III and IV with spines on prolaterodorsal face ( Fig. 37 A, C View FIGURE 37 ). Tibia IV without spines on dorsal surface ( Fig. 37 D View FIGURE 37 ). Ventral pseudoscopulae occupying 30% of tarsus I, 50% of II, 100% of III and IV and 20% of metatarsus IV. Pseudoscopula of tarsi I and II and metatarsus IV with setae spaced, forming diffuse group of bristles; on tarsi III and IV, compact. Hirsute legs ( Fig. 37 View FIGURE 37 A–D). Carapace, chelicerae, sternum, coxae, trochantera, femora, patellae, tibiae, metatarsi and tarsi reddish brown; tibia of palp paler than other articles; abdomen pale brown ( Fig. 36 A View FIGURE 36 ).
