The external morphology of adult A. melanisans Oberthür, 1917 is described and illustrated. The results obtained were compared with other studies already published on the external morphology of Nymphalidae - Danainae: Brassolinae: Brassolini sensu CASAGRANDE (2004), Morphinae: Morphini sensu LAMAS (2004a), Ithomiinae and Charaxinae. A pattern for the morphological characterization of the genus is presented. It is the first detailed study of the morphology of a species of Acraeini, therefore contributing with information on characters useful for the phylogenetic analysis of the Neotropical species.
