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).
