Taxonomy
editDayrat (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.[1]
