Taxonomy
The species composition of Tochuina was clarified in 2020 as a result of an integrative taxonomic study of the family Tritoniidae.[3] 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.[3]

Species within the genus Tochuina include:
- Tochuina gigantea (Bergh, 1904)
