Etymology. The epithet refers to the country where the species was found. To be treated as a Latin adjective.

Diagnosis. Males of A. colombianus  sp. nov. are similar to those of A. duckei Galiano, 1967  by the shape of the retroventral tibial apophysis (RvTA), sperm duct (SD) and tegular lobe (TL). However, they can be distinguished by the slender and larger lateral embolic apophysis ( LEA), and cymbial careen, a bilobed process on the embolic disc (PED), and a shorter RTA ( Figs 3a –cView FIGURES 3, 20e –gView FIGURES 20).

Description. Male (holotype). Total length: 2.56. Carapace brown with two posterior dark brown marks, 1.37 long, 0.96 wide, 0.80 high ( Fig. 16cView FIGURES 16). OC dark brown with dark orange hairs, 0.59 long. Anterior eye row 0.97 wide and posterior 0.79 wide. Sternum yellow, 0.57 long, 0.42 wide. Labium yellow, 0.12 long, 0.16 wide. Chelicerae yellow with four tiny retromarginal teeth and one promarginal tooth. Palp yellow with femur and patella with white hairs, a curved retroventral tibial apophysis (RvTA), long tegular lobe, slender lateral embolic apophysis and embolus, pointed process on embolic disc (PED), embolic disc spur (EDS), and short RTA, and a large cymbial careen (CC) ( Figs 3a –dView FIGURES 3, 20e –gView FIGURES 20). Legs 4312, all yellow.
