Etymology. The epithet is a noun in apposition that honors Sua, the goddess of sun (also known as Sue or Xué) in the Muisca mythology, indigenous people that inhabited the region where the species was found, in the central Andean highlands of the present-day Colombia's Eastern Range

Diagnosis. Males of A. sua sp. nov. are similar to those of A. mae  sp. nov. and A. quimbaya  sp. nov. by their RTA shapes, but can be distinguished from those by their combined presence of a RTA with the ventral lobe longer and pointed, and the presence of an embolar disc spur (EDS) ( Figs 12a –bView FIGURES 12, 22e –fView FIGURES 22). Females of A. sua sp. nov. are similar to those of A. mae  sp. nov., A. sie sp. nov. and A. somondoco  sp. nov. by the general disposition of the internal structures of the epigyne, but can be distinguished from those by their more anteriorly placed copulatory openings, longer copulatory ducts, anterior rounded spermathecae, and single rounded, medial pocket in the epigyne ( Figs 12c –dView FIGURES 12, 25c, 25iView FIGURES 25).

Description. Male (holotype). Total length: 2.77. Carapace dark brown with a dorsal lighter mark, 1.46 long, 1.02 wide, 0.77 high ( Fig. 18cView FIGURES 18). OC black, 0.75 long. Anterior eye row 1.15 wide and posterior 1.00 wide. Sternum brown, 0.60 long, 0.48 wide. Labium brown, 0.16 long, 0.19 wide. Chelicerae brown with four or five retromarginal and two promarginal teeth. Palp brown with rounded tegular lobe (TL), long embolic filament (EF), embolar disc spur present (EDS), bilobed RTA, with the ventral lobe long and finger-like ( Figs 12a –bView FIGURES 12, 22e –fView FIGURES 22). Legs 4312, all yellow, I darker in coloration, with femur I dark brown. Leg macrosetae: femur, I d 1 di; II –IV d 2 di, p 1 di; patella, III –IV r 1 me, tibia, I v 2-2 -2; II v 2-2 -2, p 1 di; III v 1 -0-1, p 1 pr, r 0-1-1; IV v 1 -0-1, p 0-1-1, r 1-1-1; metatarsus, I v 2-2; II v 2-2, p 1 di; III v 2 -0-1, p 1-0-2, r 1-0-2; IV v 1 -0-1, p 1-0-2, r 1-1-2. Abdomen creamcolored with a reticulated pattern of brown marks and spots ( Fig. 18cView FIGURES 18).

Female (paratype). Total length 2.89. Carapace brown with a posterior lighter stripe, 1.50 long, 1.12 wide, 0.72 high ( Fig. 18dView FIGURES 18). OC black, 0.82 long. Anterior eye row 1.14 wide and posterior 1.01 wide. Sternum brown, 0.60 long, 0.48 wide. Labium brown, 0.17 long, 0.22 wide. Chelicerae brown, with four retromarginal and two promarginal teeth. Legs 4312, all yellowish with brown marks. Leg macrosetae: femur, I –IV d 1 di; patellae, III –IV r 1 me; tibiae, I v 2-2 -2; II v 2-2 -2, p 1 di; III v 1 pr, p 1-0-1, r 1-0-1; IV v 1 pr, p 1-0-1, r 1-0-1; metatarsus, I v 2-2; II v 2-2, p 1 di; III v 2 -0-1, p 1-0-2, r 1-0-2; IV v 1 -0-1, p 1-0-2, r 1-1-2. Abdomen dark brown with dorsal creamcolored marks ( Fig. 18dView FIGURES 18). Epigyne ( Figs 12c –dView FIGURES 12, 25c, 25iView FIGURES 25) with anterior and medial copulatory openings, very long copulatory ducts, a posterior single medial pocket, anterior rounded spermathecae, and medial oval spermathecae.

Comments. The type material was collected in beating low vegetation and in Winkler traps in a secondary Andean forest, in the same locality with the type specimens of A. chie  sp. nov., so they are here considered to be sympatric.

Distribution. Colombia (Boyacá) ( Fig. 27View FIGURE 27). Known altitudinal distribution: 1152–1163 m.
