Genus Cuthona Alder & Hancock, 1855

Remarks. A phylogenetic review of the aeolid family Tergipedidae by Cella et al. (2016) found that this family was not monophyletic. In order to keep the monophyly of the group, the authors established a new classification uniting the Tergipedidae , Eubranchidae and Calmidae under the older family name Fionidae . Additionally, they reclassified many species to recover the phylogeny of the genera within this family. For instance, several species that before were classified as Cuthona , including many undescribed species, were found to be monophyletic within all the members of Tenellia and thus, transferred to the genus Tenellia . It is likely, therefore, that some of the species listed here as Cuthona are actually Tenellia .
