Tayuva lilacina was originally posted at these websites as Discodoris lilacina, that is the name most authors used, though it is known under a variety of different names. I place it in the genus Tayuva according to:
Dayrat, B. 2010. A Monographic Revision of Basal Discodorid Sea Slugs (Mollusca: Gastropoda: Nudibranchia: Doridina). Proceedings of the California Academy of Sciences 61, suppl I: 1-403.
