Phyllidiopsis sp. a

Sister taxon to Phyllidiopsis burni (supported by a bootstrap value of 100 in the 16S analysis) is a clade composed of six specimens which look very similar to P. krempfi . This clade, Phyllidiopsis sp. a (Fig. 7.3a–d), is characterised by black rhinophores with a pink to pale pink base, whereas P. krempfi (including the P. pipeki colour morphs) has rhinophores with black tips and posterior sides, but pink on the anterior faces. The boundary between the black rhinophore and the pink base runs diagonally in P. krempfi and not horizontally as in Phyllidiopsis sp. a (compare Fig. 7.1i–j vs. Fig. 7.3a–d). The rims of the rhinophores are angled and very low, with pustules on the posterior side. The narrow mantle edge is pink. The anal opening occurs on a white to pink tubercle. All six specimens of this clade were only collected in North Sulawesi (Lembeh Strait, Sangihe Island, and Bangka Island). Interestingly, molecular barcoding resulted only in 16S sequences and no CO1 sequence in all six specimens. Species delimitation tests based on the 16S data set clearly indicate this clade as a distinct species with a support value of 100 in the 16S tree ( Fig. S1 ). No chemical analyses were performed on any specimens of this clade.
