Hello Albert,
this nudi you have here is probably of the new species discovered this year called Janolus flavoanulatus. See what they say here about the difference with savinkini: the latter should have yellowish rhinophores with blue tips. I also include a link to areal savinkini. I have also corrected my own Janolus which I think were all flavoanulatus as well:

  Thanks, Marta for the info and update. Posted 5 years ago

The Janolus flavoanulatus

The specific name, flavoanulatus refers to the yellow subapical ring of the cerata (from the Latin words flavus, yellow and anulatus, ringed). The body and the cerata of Janolus flavoanulatus are translucent, the latter with a purple subapical ring merging towards the tip into bright blue, and a yellowish ring below the purple ring. The rhinophores are brown-reddish with white tips. The caruncle is pale yellowish/cream. There is a bluish margin to the foot, the 'tail' is blue.
