Hamearis lucina, the Duke of Burgundy, the only member of the genus Hamearis, is a European butterfly in the family Riodinidae. For many years, it was known as the "Duke of Burgundy fritillary", because the adult's chequered pattern is strongly reminiscent of "true" fritillaries of the family Nymphalidae.

Nemeobiinae is a subfamily of Riodinidae, the metalmark family. The subfamily's members consist entirely of Old World members of the Riodinid family. Recent revisions to the subfamily have begun to include members located within the New World as well, however, the subfamily continues to encompass the entirety of the Old World Riodinids.
