This appears very similar in colour to the Indo-West Pacific species Pleurobranchus albiguttatus and I previously labelled it as Pleurobranchus cf. albiguttatus on the Forum. I have now identified it as Pleurobranchus atlanticus, a species previously considered a synonym of Pleurobranchus areolatus. See Anne Dupont's message below where I discuss its identity in more detail.
Pleurobranchus evelinae Thompson, 1977 is also a synonym [see message.]
