==Taxonomy== The species composition of ''Tochuina'' was clarified in 2020 as a result of an integrative taxonomic study of the family Tritoniidae.<ref name=KM2020>Korshunova, T.; Martynov, A. (2020). [https://doi.org/10.1371/journal.pone.0242103 Consolidated data on the phylogeny and evolution of the family Tritoniidae (Gastropoda: Nudibranchia) contribute to genera reassessment and clarify the taxonomic status of the neuroscience models ''Tritonia'' and ''Tochuina''.] PLOS ONE. 15(11): e0242103.</ref> ''Tochuina'' differs from ''Tritonia'' in having a non-bilobed oral veil and the clade is supported by DNA phylogeny. An interesting finding was that the tritoniid genus ''Tochuina'' not only shows an intriguing morphological similarity to ''Doridoxa'' and ''Heterodoris'' but clusters close to these genera, which themselves cluster with the family Arminidae, in a molecular tree within the Dendronotoidea.<ref name=KM2020 />
