Type material. Holotype male from 1° 25’ 29.38” S 48° 26’ 16.86” W, Parque Ambiental de Belém (Utinga), Belém, Pará, Brazil, ii.2010, G. H. F. Azevedo et al. leg. ( UFMG 9918 View Materials ). GoogleMaps
Etymology. The specific name is a noun in apposition from the type locality name, Utinga.
Diagnosis. Males of A. utinga resemble those of A. nattereri ( Fig. 67 View FIGURE 67 A–C), A. vilhena ( Fig. 75 View FIGURE 75 A–C), A. harveyi ( Fig. 78 View FIGURE 78 A–C), A. itapitocai ( Fig. 83 View FIGURE 83 A–C), and A. xingu ( Fig. 94 View FIGURE 94 A–C) by the BTA displaced dorsally on the prolateral tegular surface ( Fig. 103 A View FIGURE 103 ); they resemble those of A. rufipes ( Fig. 72 View FIGURE 72 A–C), A. nattereri ( Fig. 88 View FIGURE 88 A–C), A. itaqui ( Fig. 91 View FIGURE 91 A–C), A. mesa ( Fig. 97 View FIGURE 97 A–C) and A. caxiuana ( Fig. 100 View FIGURE 100 A–C) by the well-developed PA, rebordered. They differ from those of other species in the group nattereri by the palpal tibia and cymbium being paler than other articles; the PI prominent, almost reaching the border of embolus on dorsal view, and longer than other keels ( Fig. 103 View FIGURE 103 A–C).
MALE (UFMG 9918): Total length 11.87; Carapace, long 5.37; wide 5.12. Carapace rounded. Anterior eye row slightly procurved, posterior row recurved ( Fig. 101 B View FIGURE 101 ). With row of short bristles on clypeus border. Without bristles 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. 101 C View FIGURE 101 ). Rastellum protuberant, inverted Vshaped, hirsute, without spines apically ( Fig. 101 View FIGURE 101 E–F). Chelicerae with eight denticles along prolateral row of teeth. Prolateral row with six megateeth. Retrolateral row with five megateeth ( Fig. 101 D View FIGURE 101 ). Patella and tibia III with distal crown of well-developed thorns, on patella III interrupted in middle and on tibia III not interrupted in middle and recurved ( Fig. 102 View FIGURE 102 A–B). Patellae III and IV with spines on prolaterodorsal face ( Fig. 102 A, C View FIGURE 102 ). Tibia IV without spines on dorsal surface ( Fig. 102 D View FIGURE 102 ). Ventral pseudoscopulae occupying 50% of tarsus I, 70% 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 dark brown; tibia of palp and cymbium paler than other articles.
