Comment from Nathalie Yonow on photo #12916
The black rhinophores point to not Phyllidiopsis, so I think this is rudmani with a few extra black bits centrally.

Comment from Richard Willan on photo #16595
This is a very important photo because it shows mating occurring between 2 different species of Phyllidiella – Phyllidiella rudmani (on top) and Phyllidiella lizae (below). This demonstrates cross-species mating does sometimes occur in phyllidiid nudibranchs. It has also been demonstrated in Chromodorididae (Risbecia spp.) and in Aglajidae bubble snails (Chelidonura spp.).

A juvenile individual.

Comment from Nathalie Yonow: Possibly. Normally in Phyllidiella rudmani the black lines do not meet in front of the rhinophores, but I can’t think of any other species except Phyllidiella krempfi, which has that distinctive line in front of the rhinophores. However, Phyllidiella krempfi usually has more black. The black frontal line and compound tubercles seem to me more like Phyllidiella krempfi but the all black rhinophores are NOT Phyllidiella krempfi.

By contrast, Phyllidiopsis pipeki is characterised by compound pustules and heavy black radial bars extending from the longitudinal lines to the margin.

A nice photo of a typical individual actively crawling.
