This is most likely an undescribed aeolid of the genus Cumanotus  Odhner, 1907, I label it Cumanotus sp. 01. It was identified by Dr. Richard C. Willan, let me quote:
"My guess is that this aeolid is an undescribed tropical species of Cumanotus. The points that match are:
Short yet broad body;
Long smooth rhinophores;
Enlarged front of foot with rounded anterior border;
Very long and slender cerata with uniformly narrow digestive diverticulum internally.
The family for Cumanotus is not resolved at present. Some workers place it in Flabellinidae, whilst others place it in its own family Cumanotidae."
I followed WoRMS and placed it in the family Flabellinidae  Bergh, 1889.
Species of the genus Cumanotus are usually found in temperate (cold) waters of
Northeastern Atlantic Ocean, Cumanotus beaumonti,
Mediterranean Sea, Cumanotus beaumonti,
Eastern Atlantic Ocean, Cumanotus beaumonti, Cumanotus cuenoti, or
Northeastern Pacific Ocean, Cumanotus fernaldi, Cumanotus sp.
Korshunova et al. (2017) place the genus Cumanotus  Odhner, 1907 in the family Cumanotidae  Odhner, 1907.
Korshunova, T.; Martynov, A.; Bakken, T.; Evertsen, J.; Fletcher, K.; Mudianta, W.; Saito, H.; Lundin, K.; Schrödl, M.; Picton, B. (2017). Polyphyly of the traditional family Flabellinidae affects a major group of Nudibranchia: aeolidacean taxonomic reassessment with descriptions of several new families, genera, and species (Mollusca, Gastropoda).
