Tayuva lilacina is a pale brown species decorated with irregular darker blotches. The notum is covered with small papillae that vary in length. The branchia are cream, frosted with white. Lines of patches on each side of the notum are often darker than the rest. It is characterised by its ability to autotomise large sections of the mantle as described by many authors.
Tayuva lilacina was posted on 29 August 2003 at these websites as Discodoris lilacina, that is the name most authors used, though it is known under a variety of different names.
Dayrat (2010 moved it into the genus Tayuva  Er. Marcus & Ev. Marcus, 1967.
This species is very similar to Sebadoris fragilis (Alder & Hancock, 1864) [Doris] which is also known under a variety of different names. Externally they differ by their sizes, Tayuva lilacina is usually much smaller, seldom larger than 4 cm, Sebadoris fragilis grows up to 12 cm, Dayrat (2010) writes "If preseved specimens measure more than 60 mm they have little chance to be part of lilacina". Both species are very variable and/or part of a species complex.
