Phyllidia sp. 3

Our two specimens grouped with one sequence extracted from GenBank (AF430363), an animal collected from 35 m depth in New Caledonia and assigned to P. ocellata by Valdés (2003). These three specimens form a distinct clade, confirmed by species delimitation tests, and form a sister clade to P. elegans / P. coelestis . One of our specimens, Phex15Bu1 (Fig. 4.3a), has the same pattern as Phyllidia sp. 3 in Gosliner et al. (2018): it has a bluish tinge with an irregular yellow mantle rim and two longitudinal black lines that are slightly wavey, a black curved U-shaped line in front of the rhinophores, and black marks on the dorsal midline. The tubercles are large, single, and round, not topped with yellow pigment: in fact, all tubercles are white in this species. The animal depicted in Gosliner et al. (2018) only differs in so far as the yellow parts appear more orange. Unfortunately, no photograph is available of our living second specimen, but the black pattern is similar. The clade is supported by a bootstrap value of 100 ( Fig. 13 ) and shows no intraspecific variability (Table S4). No chemical analyses were performed for specimens of this clade.
