''A radical solution: The phylogeny of the nudibranch family Fionidae.''
PLoS ONE. 11(12): e0167800. Miller (2004) restricted the genus ''Cuthona'' Alder & Hancock, 1855 to the type species, ''C. nana'' (Alder & Hancock, 1842), and transferred to the genus ''Trinchesia'' the rest of the species previously included in ''Cuthona''. Miller has been followed by some authors, and has not been followed by others - and there is currently much instability on the extension and contents of these two genera. Cella et al., 2016 hypothesised that the genus ''Tenellia'' should include many former ''Cuthona'' and ''Trinchesia'' species, with others being placed in new genera. Until the species listed here are re-investigated they are left by WoRMS in the genus ''Trinchesia''. They also showed that the type taxon of ''Trinchesia'' is a species complex. The species were partly allocated to other genera as a result of another study, being placed in several smaller genera, ''
