Figs 63–67 View FIGURE 63 View FIGURE 64 View FIGURE 65 View FIGURE 66 View FIGURE 67 , Map 5 View MAP 5

Pachyloscelis nattereri Doleschall   in Ausserer, 1871: 139 (holotype ♀, Rio Negro , Amazonas, Brazil, NWMW, not located).

Actinopus nattereri: F. O. Pickard-Cambridge, 1896: 730   ; World Spider Catalog, 2020.

Note. The material examined was attributed to A. nattereri   by the size and disposition of the eyes and by the congruent geographical distribution. The provenance of the material here studied is coincident with the route traveled by the collector of the type specimen, Johann Natterer ( Papavero, 1971).

Diagnosis. Males of A. nattereri   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. caxiuana   ( Fig. 98 A View FIGURE 98 ) by the bluishgray coloration of the dorsum of abdomen ( Figs 63 A View FIGURE 63 , 67 E View FIGURE 67 ); further resemble those of A. caxiuana   , A. ipioca   and A. itaqui   by the tibia of palp paler than other articles; they resemble those of those of 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), 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 prolateral tegular surface ( Fig. 67 A View FIGURE 67 ); they resemble those of A. vilhena   , A. xingu   and A. utinga   by keels, as seen in prolateral view, very closed to each other ( Fig. 67 A View FIGURE 67 ). They differ from those of all other species of the nattereri   group by the overlapping keels; tegulum subquadrate; and by a slightly swelling on prolateral PS, visible on dorsal view ( Fig. 67 View FIGURE 67 A–C). Females resemble A. rufipes   by the unilobed receptacles and those of A. ipioca   by the pore distribution reaching nearly 60% of receptacle surface; they differ from those of all species of the group by the rounded, divergent receptacles ( Fig. 67 D View FIGURE 67 ).
