See text Mangelia is a large genus of sea snails, marine gastropod mollusks in the family Mangeliidae.

Among the remaining accepted names a good number are still in doubt and are little known.

This genus was named Mangelia by Leach and accepted by Risso in 1826.

Later, some authors, such as Lovén in 1846, spelled it inadvertently as Mangilia, to honor the Italian malacologist Mangili Giuseppe (1767-1829).

[3][4] The genus Mangelia used to be defined by a multispiral protoconch, contrary to the genus Mangeliella Bucquoy, Dautzenberg & Dollfus, 1883 which was defined by a paucispiral protoconch.
