Notes from Brunckhorst,1993:
Phyllidiopsis pipeki Large and elongate, growing to 85mm. Bright pink colouration and consistently two black longitudinal lines only. The lines may be broken, and occasionally there can be a few black spots or rays extending to the mantle edge. The large tubercles, either single or compound have a steep pink base and a rounded white tip. They are sparsely scattered over dorsum. The rhinophores are pink with a black tip and a black line down posterior edge.
Two other species with similarly coloured rhinophores:
Phyllidiopsis krempfi, Large species characterised by predominantly pink coloration, and broad based multicompound tubercles with paler apices. Apart from two primary longitudinal black lines, other black lines of variable size occur irregularly. Rhinophores pink on anterior face and around base, black on apex and posterior face.
Phyllidiopsis fissuratus, which is also pink and black but is extremely tuberculate, with very tall compound and coalesced tubercles with deep black valleys between. It also has a translucent raised rim around the raised rhinophore pockets and a smooth tall raised pink anal papilla.
