Fionidae is a family of sea slugs, aeolid nudibranchs, marine gastropod molluscs in the superfamily Fionoidea.[1]
Taxonomic history
[edit]This family was expanded to include Tergipedidae, Eubranchidae and Calmidae as a result of a molecular phylogenetics study.[2] This was reversed in 2017 with further DNA evidence and a re-interpretation of genus and family characteristics.[3]
Genera
[edit]According to Korshunova et al. (2025), genera within the family Fionidae include[4]:
- Fiona Alder & Hancock [in Forbes & Hanley], 1853
- Tergiposacca Cella, Carmona, Ekimova, Chichvarkhin, Schepetov & Gosliner, 2016
Other genera not mentioned in Korshunova et al. (2025) include[1]:
- Zatteria Eliot, 1902
