Callistege Hübner. The genus Callistege was synonymized with Euclidia Ochsenheimer by Goater et al. (2003), but retained as a subgenus. Callistege is reinstated as a separate genus. The three North American species were originally described in Euclidia, so the associations are Callistege intercalaris, comb. rev., C. diagonalis, comb. rev., and C. triangula, comb. rev.
