Forewing ( Fig. 26A–D View FIGURE 26 ) reddish brown on anterior half, becoming black towards apex; with one or two transverse narrow ivory stripes ( Fig. 26A, B View FIGURE 26 ): one on anterior half of wing, transcommissural, not reaching costal margin; and another (absent in some specimens) restricted to corium, reaching costal margin, aligned to clavus apex ( Fig. 26C, D View FIGURE 26 ). Other characters as in males above.

Male terminalia. Base of connective arms ( Fig. 25E View FIGURE 25 ) with a V-shaped dorsal rim. Style ( Fig. 25E View FIGURE 25 ) with apodeme wide and long, 0.9 times as long as apophysis length; inner lobe subquadrate; apical portion not extending to connective apex. Aedeagal shaft ( Fig. 25F View FIGURE 25 ), in lateral view, with preapical dorsal spiniform process extending dorsally slightly beyond dorsal margin of lateral projections. Other characters as in A. amazonica sp. nov.

Female terminalia. Abdominal sternite VII ( Fig. 26E View FIGURE 26 ), in ventral view, with posterior margin with a pair of digitiform projections on median third, area between projections concave, not projected posteriorly.

Etymology. The specific epithet ‘ colombiana ’ is an adjective and refers to the country where the types of this species were found, Colombia.

Remarks. One male and one female specimen ( Figs. 25A, B View FIGURE 25 , 26A, B View FIGURE 26 ) of A. colombiana sp. nov. were classified as conspecific in the species delimitation analyses ( Fig. 2 View FIGURE 2 ). These results indicate that the species is sexually dimorphic in color pattern. As part of A. horvathi s.l., the males of this species are difficult to distinguish from other species within the complex. However, A. colombiana sp. nov. has some unique morphological characters that can be used for its differentiation, such as the pronotum ( Fig. 25A View FIGURE 25 ) anterolateral ivory-colored maculae, which are very small and inconspicuous dorsally, and the style ( Fig. 25E View FIGURE 25 ) with the inner lobe subquadrate.
