Lycaeninae, the coppers, are a subfamily of the gossamer-winged butterflies (Lycaenidae).

Consequently, the delimitation of the Lycaeninae is by no means definitely resolved; many genera await conformation of placement.

Regardless, it is today generally considered better to restrict the Lycaeninae to the immediate relatives of the type genus Lycaena, and one or two clades close to that group.

Finally, there are some genera of uncertain status as regards their systematics and taxonomic validity.

They might, if valid, be members of the monophyletic Lycaeninae, but this requires confirmation:
