Diagnosis. The embolic disc and embolus of A. santanae  ( Figs 15View FIGURE 15 A, 16A) are similar to those of A. duckei  , A. colombianus  , A. nigrigenu  sp. nov. ( Fig. 12View FIGURE 12 C) and A. simplex  sp. nov. ( Fig. 14View FIGURE 14 C): there are two dPED and the vPED is proximal and projects retrolaterally; also, the embolus is thicker and sickle-shaped ( Figs 15View FIGURE 15 A, 16A). However, A. santanae  can be distinguished by the short RvTA with one tooth on the border ( Figs 15View FIGURE 15 B, 16D), being slender and sinuous in A. duckei  and A. colombianus  , rounded with two teeth in A. nigrigenu  sp. nov. ( Fig. 12View FIGURE 12 D) and finger-shaped in A. simplex  sp. nov. ( Fig 14View FIGURE 14 D). The females of A. santanae  ( Fig. 16View FIGURE 16 I), A. duckei  , A. bifidus  sp. nov. ( Fig. 21View FIGURE 21 F) and A. simplex  sp. nov. ( Fig. 14View FIGURE 14 F) have rounded secondary spermathecae near the copulatory openings. Among these species, A. santanae  is closer to A. duckei  in having large secondary spermathecae (twice the girth of the copulatory duct) that are separated at least by one diameter and dorsal coupling pocket near the border of the epigyne, but can be distinguished in having a deeper pocket (shallow pocket near the border in A. duckei  ).

Description. See Galiano (1967).

Variation. Palp ( Figs 15View FIGURE 15 A –C, 15E –G, 15I –K, 15M –O, 16A –H): RvTA is generally short with one tooth on the superior border and with a serrated ventral border ( Figs 16View FIGURE 16 B, 16D, 16F, 16H). Its shape varies from rectangular ( Figs 15View FIGURE 15 B, 16D), or trapezoidal ( Figs 16View FIGURE 16 B, 16H) to rounded ( Fig. 16View FIGURE 16 F); the tegular lobe can be parallel to the longitudinal axis of the palp ( Figs 16View FIGURE 16 A, 16C, 16E, 16G) or prolaterally curved ( Fig. 15View FIGURE 15 A). The embolic disc has two ( Figs 15View FIGURE 15 A, 16G) or three ( Figs 16View FIGURE 16 A, 16C) distal processes. Epigyne ( Figs 15View FIGURE 15 D, 15H, 15L, 15P, 16I –L): epigynal plate can have the posterior border without modifications ( Fig. 15View FIGURE 15 D) or be expanded and bilobed ( Figs 15View FIGURE 15 H, 15L, 15P); the copulatory duct is medium-sized ( Figs 16View FIGURE 16 I, 16K, 16L) or very long ( Fig. 16View FIGURE 16 J); the coupling pocket has different degrees of depth ( Figs 16View FIGURE 16 I –L).

Distribution. States of Amapá and Pará ( Brazil) ( Fig. 30View FIGURE 30).
