*It is the opinion of two of the authors of the species that it is likely the images above represent Aeolidia filomenae Kienberger, Carmona, Pola, Padula, Gosliner & Cervera, 2016.
Aeolidia filomenae Kienberger, Carmona, Pola, Padula, Gosliner & Cervera, 2016 has recently been separated from Aeolidia papillosa after a recent molecular study of the species.
I will endeavor to find specimens of Aeolidia filomenae and Aeolidia papillosa to photograph in detail. However, I am told that the only sure way of identifying each species is by sequencing, so these species could be extremely difficult to tell apart, especially in SW England as no material was sequenced in the recent study. It is therefore not known if we have Aeolidia filomenae or Aeolidia papillosa, or both here.
I personally feel that specimens from the SW should be recorded as Aeolidia papillosa untill more is known about both species or until more are sequenced. It is also possible that more cryptic species may be found within Aeolidia papillosa.
