Fionoidea is a superfamily of nudibranchs, shell-less marine gastropod molluscs or sea slugs, in the suborder Aeolidacea. The families within Fionoidea were shown to be monophyletic on DNA evidence and a re-interpretation of family characteristics was provided.
Families
In 2017, Bouchet and colleagues listed the following families inside Fionoidea:
- Family Calmidae Iredale & O’Donoghue, 1923
- Family Cuthonellidae M. C. Miller, 1977
- Family Cuthonidae Odhner, 1934
- Family Eubranchidae Odhner, 1934
- Family Fionidae Gray, 1857
- Family Lomanotidae Bergh, 1890
- Family Pinufiidae Er. Marcus & Ev. Marcus, 1960
- Family Tergipedidae Bergh, 1889
- Family Trinchesiidae F. Nordsieck, 1972
2025 revision
