Diagnosis. The embolic disc and embolus of A. santanae   ( Figs 15 View FIGURE 15 A, 16A) are similar to those of A. duckei   , A. colombianus   , A. nigrigenu   sp. nov. ( Fig. 12 View FIGURE 12 C) and A. simplex   sp. nov. ( Fig. 14 View FIGURE 14 C): there are two dPED and the vPED is proximal and projects retrolaterally; also, the embolus is thicker and sickle-shaped ( Figs 15 View FIGURE 15 A, 16A). However, A. santanae   can be distinguished by the short RvTA with one tooth on the border ( Figs 15 View FIGURE 15 B, 16D), being slender and sinuous in A. duckei   and A. colombianus   , rounded with two teeth in A. nigrigenu   sp. nov. ( Fig. 12 View FIGURE 12 D) and finger-shaped in A. simplex   sp. nov. ( Fig 14 View FIGURE 14 D). The females of A. santanae   ( Fig. 16 View FIGURE 16 I), A. duckei   , A. bifidus   sp. nov. ( Fig. 21 View FIGURE 21 F) and A. simplex   sp. nov. ( Fig. 14 View 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 15 View 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 16 View FIGURE 16 B, 16D, 16F, 16H). Its shape varies from rectangular ( Figs 15 View FIGURE 15 B, 16D), or trapezoidal ( Figs 16 View FIGURE 16 B, 16H) to rounded ( Fig. 16 View FIGURE 16 F); the tegular lobe can be parallel to the longitudinal axis of the palp ( Figs 16 View FIGURE 16 A, 16C, 16E, 16G) or prolaterally curved ( Fig. 15 View FIGURE 15 A). The embolic disc has two ( Figs 15 View FIGURE 15 A, 16G) or three ( Figs 16 View FIGURE 16 A, 16C) distal processes. Epigyne ( Figs 15 View FIGURE 15 D, 15H, 15L, 15P, 16I –L): epigynal plate can have the posterior border without modifications ( Fig. 15 View FIGURE 15 D) or be expanded and bilobed ( Figs 15 View FIGURE 15 H, 15L, 15P); the copulatory duct is medium-sized ( Figs 16 View FIGURE 16 I, 16K, 16L) or very long ( Fig. 16 View FIGURE 16 J); the coupling pocket has different degrees of depth ( Figs 16 View FIGURE 16 I –L).
