Type material. Holotype male from [05° 49’ S 37° 24’ W], Aldeia Yanomami , Alto Alegre, Rio Grande do Norte, Brazil, 20–30.iv.2005, C. Kirsch leg. ( IBSP 111837 View Materials ). GoogleMaps

Etymology. The specific name is a patronym in honor of Australian arachnologist Mark S. Harvey, who kindly received the first author at the Western Australian Museum, Perth.

Diagnosis. The male of A. harveyi resembles those of A. nattereri ( Fig. 67 View FIGURE 67 A–C), A. vilhena ( Fig. 75 View FIGURE 75 A–C), A. itapitocai ( Fig. 83 View FIGURE 83 A–C), A. xingu ( Fig. 94 View FIGURE 94 A–C) and A. utinga ( Fig. 103 View FIGURE 103 A–C) by BTA displaced dorsally in relation to a middle longitudinal line along the prolateral tegular surface ( Fig. 78 A View FIGURE 78 ); it differs from those of A. nattereri , A. vilhena , A. xingu and A. utinga by keels not overlapping in prolateral view ( Fig. 78 A View FIGURE 78 ) and from all other species of the group nattereri by the short, inconspicuous PA and PAc reaching only 10% of PI, as seen on dorsal view ( Fig. 78 View FIGURE 78 A–C).

MALE (IBSP 111837): Total length 12.25; Carapace, long 6.75; wide 6.25. Carapace rounded. Anterior eye row slightly procurved, posterior row recurved ( Fig. 76 B View FIGURE 76 ). With few short bristles between AME-clypeus, between ALE–ALP, between posterior eyes-fovea and lateral eyes-edge of carapace. Sternum with eight sigilla fused medially, two distal sigilla more fused than others ( Fig. 76 C View FIGURE 76 ). Rastellum protuberant, inverted Vshaped, hirsute, without spines apically ( Fig. 76 View FIGURE 76 E–F). Chelicerae with seven denticles along prolateral row of teeth. Prolateral row with six megateeth. Retrolateral row with six megateeth and two denticles between two medial teeth and two basal megateeth ( Fig. 76 D View FIGURE 76 ). Patella and tibia III with distal crown of well-developed thorns, not interrupted in middle ( Fig. 77 View FIGURE 77 A–B). Patellae III and IV with spines on prolaterodorsal face ( Fig. 77 A, C View FIGURE 77 ). Tibia IV without spines on dorsal surface ( Fig. 77 D View FIGURE 77 ). Ventral pseudoscopulae occupying 30% of tarsus 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, chelicerae, sternum, coxae, trochantera, femora, patellae, tibiae, metatarsi and tarsi reddish brown; Abdomen pale brown ( Fig. 76 A View FIGURE 76 ).
