Taxonomy
Dayrat (2010) places ''Discodoris lilacina''
(Gould, 1852) in the genus ''Tayuva''
Marcus & Marcus, 1967 (type species by original designation: ''Tayuva ketos''
Marcus & Marcus, 1967, from Pacific coast of Mexico) on the basis of a synapomorphy “a muscular wall in the distal portion of the reproductive system”. ''Discodoris lilacina'' in the current sense (e.g. Valdés, 2002) is indicated as “Tayuva lilacina of tropical Indo-West Pacific”, and several worldwide species currently recognized as valid are subsumed: ''Tayuva ketos'' as “Tayuva lilacina of Panamic Eastern Pacific” (contra Valdés, 2002 who holds ''Tayuva'' as a synonym of ''Discodoris'' and ''Discodoris ketos''
(Marcus & Marcus, 1967) as a valid species); ''Peltodoris hummelincki''
Marcus & Marcus, 1963 as “Tayuva lilacina of the Caribbean Sea”; ''Discodoris maculosa''
Bergh, 1884 as “Tayuva lilacina of the Mediterranean and Eastern European Atlantic”. Dayrat nevertheless acknowledges (p. 78) that “The name ''T. lilacina'', as used here, likely refers to a species complex”. Alternatively these could be treated as valid species under ''Discodoris'', following Valdés' (2002) view.
