The present paper is the final part of a study of the external morphology of Preponini, which compares the abdomen and genitalia of Archaeoprepona demophon demophon (Linnaeus, 1758), Archaeoprepona licomedes licomedes (Cramer, 1777) and Prepona pylene pylene Hewitson, [1854], through descriptions and illustrations. The results are compared with three other species, Prepona claudina annetta (Gray, 1832), Memphis moruus stheno Hübner, [1819] and Zaretis itys itylus (Westwood, 1850). The abdomen is commonly the most informative tagma for butterflies. In Charaxinae, this tagma supports diagnoses of both genera and species, besides providing a solid morphological base for recent molecular findings for Preponini.
