Mangeliidae is currently a monophyletic family of small to medium-sized sea snails, marine gastropod mollusks in the superfamily Conoidea. Prior to 2011, both the subfamilies Mangeliinae and Oenopotinae had been placed in the family Conidae. In 2011, Bouchet, Kantor et al merged the two subfamilies into one taxon, which they elevated to the rank of family. This was based on anatomical characters and a dataset of molecular sequences of three gene fragments.
