Etymology. The specific name refers to Floresta Nacional de Caxiuan„, Portel, Pará, Brazil ( Map 5 View MAP 5 ).
Diagnosis. Males of A. caxiuana resemble those of A. vilhena ( Fig. 73 A View FIGURE 73 ), A. itapitocai ( Fig. 79 A View FIGURE 79 ), A. itaqui ( Fig. 89 A View FIGURE 89 ) and A. nattereri ( Figs 63 A View FIGURE 63 , 67 E View FIGURE 67 ) by the bluishgray coloration on dorsal surface of abdomen ( Fig. 98 A View FIGURE 98 ); they resemble A. nattereri , A. ipioca and A. itaqui by the palpal tibia being paler than other articles; they resemble those of A. ipioca ( Fig. 88 View FIGURE 88 A–C), A. rufipes ( Fig. 72 View FIGURE 72 A–C), A. itaqui ( Fig. 37 View FIGURE 37 A–C) and A. mesa ( Fig. 97 View FIGURE 97 A–C) by BTA placed medially on prolateral tegular surface ( Fig. 100 A View FIGURE 100 ) and differ from those of other species in the group nattereri , except A. itaqui , by PS in a horizontal line along the prolateral tegular surface, with a larger keel surface. They differ from those of A. itaqui by a larger spacing between PS–PI and PI being less developed and longer than PS in dorsal view ( Fig. 100 View FIGURE 100 A–C).
MALE (MPEG 2538): Total length 15; Carapace, long 7.62; wide 6.87. Carapace rounded. Anterior eye row slightly procurved, posterior row recurved ( Fig. 98 B View FIGURE 98 ). With few and weak short bristles between AMEclypeus, between ALE–ALP, between posterior eyesfovea and lateral eyes-edge of carapace. Sternum with 10 sigilla fused medially, two anterior and two posterior sigilla more fused than others ( Fig. 98 C View FIGURE 98 ). Rastellum protuberant, inverted V-shaped, hirsute, without spines apically ( Fig. 98 E, F View FIGURE 98 ). Chelicerae with seven denticles along prolateral row of teeth. Prolateral row with seven megateeth. Retrolateral row with six megateeth and one denticle between two basal megateeth ( Fig. 98 D View FIGURE 98 ). 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 ( Fig. 99 A, B View FIGURE 99 ). Patellae III and IV with spines on prolaterodorsal face ( Fig. 99 A, C View FIGURE 99 ). Tibia IV without spines on dorsal surface ( Fig. 99 D View FIGURE 99 ). 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 reddish brown; abdomen bluish-dark-gray ( Fig. 98 A View FIGURE 98 ).
