Archaeoprepona is a genus of Neotropical charaxine butterflies in the family Nymphalidae, native to Mexico, Central America, northern South America, and the Caribbean. The underside of their wings is pale brownish, while the upperside is dark with a distinct bright blue band.

Taxonomy

Most taxa were described before Hans Fruhstorfer coined the genus Archaeoprepona in 1916, and were therefore originally placed in other genera. This includes the type species of the genus, Archaeoprepona demophon, first described as Papilio demophon by Carl Linnaeus. Even after the description of the genus Archaeoprepona, the members have commonly been included in Prepona instead. Species in the genus Archaeoprepona:
