Species delimitation and phylogeny of Doto (Nudibranchia: Dotidae) from the Northeast Atlantic, with a discussion on food specialization

The nudibranch genus Doto is taxonomically problematic in particular, and some species are described on the notion of strict monophagy. Here we perform delimitation NE Atlantic species, as well placing them phylogenetically, using two markers: mitochondrial COI nuclear H3. We also study morphology including radular ultrastructure review food specificity. Specimens were first divided into potential ABDG both markers, these groups used input for analyses BPP, performed with markers combined H3 only. delimit 11 eight respectively. With exception one which only was available, differences found D. fragilis, split three when included lumped hystrix nested within groups. that specimens from Sweden seemingly close to maculata external have identical sequences coronata. Analysis preferences involved contradicts monophagy Doto.
