Classification and phylogeny
Previously considered to be migadopines (before 1985), amarotypines are still often treated as forming a monophyletic subfamily MigadopinaeMigadopinae
Migadopinae is a subfamily of beetles in the family Carabidae, containing the following genera:* Amarotypus Bates, 1872 * Antarctonomus Chaudoir, 1861 * Aquilex Moret, 1990 * Calathosoma Jeannel, 1938 * Calyptogonia Sloane, 1920...
with Migadopini , but the phylogeny may be (Amarotypini, (Migadopini, Elaphrini)). Alternatively, Amarotypini may form a clade with Promecognathini, again unrelated to Migadopini , though this possible relationship has been disputed.
