Type material. Holotype male from [25° 42’ 32.5764” S 51° 38’ 1.7988” W], Usina Hidroelétrica de Segredo , Pinh „o, Paraná, Brazil, R. Pinto-da-Rocha leg. ( MZSP 14718 View Materials ). GoogleMaps

Etymology. The specific name is a noun in apposition from the type locality name.

Diagnosis. Males of A. pinhao resemble those of A. hirsutus ( Fig. 37 View FIGURE 37 A–D) by the hirsute legs ( Figs 31 View FIGURE 31 A–D, 37 A–D) and those of A. ducke ( Fig. 35 View FIGURE 35 A–C), A. hirsutus ( Fig. 38 View FIGURE 38 A–C) and A. jaboticatubas ( Fig. 41 View FIGURE 41 A–C) by the wide tegulum with robust basal tegular apophysis, placed medially on prolateral tegular surface ( Figs 32 View FIGURE 32 A–C). They are readily recognized by the following combination of characters: serrated area positioned distal to PAc ( Fig. 32 A, B View FIGURE 32 ); PA continuous to PAc ( Fig. 32 A View FIGURE 32 ); PA conspicuous; BTA developed ( Fig. 32 View FIGURE 32 A–C). Additionally, they differ from those of all other species on the group pinhao by the proximal surface of BTA with a swelling ( Fig. 32 A View FIGURE 32 ).

MALE (MZSP 14718): Total length 13.27; Carapace, long 6.18; wide 6.83. Carapace anterior part tapering and slightly rounded. Anterior eye row procurved, posterior row recurved ( Fig. 30 B View FIGURE 30 ). Many bristles on ocular area, between AME-clypeus, between lateral eyes-edge of carapace, between lateral eyes and on interdistances PME–PME and PLE–PLE. Sternum with eight inconspicuous sigilla fused medially, two distal sigilla more fused than others ( Fig. 30 C View FIGURE 30 ). Rastellum protuberant, subtriangular, hirsute, without spines apically ( Fig. 30 View FIGURE 30 E–F). Denticles arranged in two rows along prolateral row of teeth. Retrolateral row decreasing in distal-proximal way, with two denticles on the edge of basal part ( Fig. 30 D View FIGURE 30 ). Patella and tibia III with distal crown of well-developed thorns, not interrupted in middle ( Fig. 31 View FIGURE 31 A–B). Patella III with spines on distal part of prolateral face. Patella III and IV with spines on prolaterodorsal face, and one spine dorsal ( Fig. 31 A, C View FIGURE 31 ). Tibia IV without spines on dorsal surface ( Fig. 31 D View FIGURE 31 ). Ventral pseudoscopulae for full of tarsi III and IV and 33% of metatarsi IV. Hirsute legs. Carapace and chelicerae dark reddish-brown; sternum and legs reddish-brown; Abdomen pale gray ( Fig. 30 A View FIGURE 30 ). Eyes: Diameters: PME 0.29, PLE 0.43, ALE 0.41, AME 0.34; MOQ: Length 1.2, front width 2.11, back width 0.96; Interdistances: PME–PME 1.8, PLE–PME 0.12, AME–AME 0.28, ALE–AME 0.75, ALE–PLE 0.54, AME–PME 0.68. Ocular area: OAL 5.03, OAW 3.7, and IF 4.92. Body: Clypeus: 0.26; Fovea: 3.09; Labium: long 1.83; wide 1.39; Chelicerae: long 3.98; wide 2.19; Sternum: long 4.18; wide 4.03. Abdomen: long 6.48; wide 5.48. Leg measurements: I: Fe 6.69/ Pa 2.56/ Ti 3.53/ Me 4.45/ Ta 3.01/ total 20.24. II: 6.55/ 2.79/ 4.3/ 5.01/ 3.06/ 21.71. III: 5.18/ 2.98/ 2.64/ 5.48/ 3.41/ 19.69.

Palp: BTA developed and placed medially on prolateral tegular surface, embolus with three keels (PAc, PS and PI) on dorsal and retrolateral faces. PAc on retrolateral face, continuous to distal part of embolus. PS inconspicuous on dorsal face ( Fig. 32 B View FIGURE 32 ). Serrated area poorly developed and distal to PAc, evident on three views, continuous to proximal part of PAc. Tegulum robust, with PA developed and proximal part of tegulum, above to PA with a swelling ( Fig. 32 View FIGURE 32 A–C).
