Taxonomy
This species was described under the name Hypselodoris fregona from the Caribbean Sea in 2013. Although Johnson & Gosliner transferred all eastern Pacific, Atlantic and Mediterranean species of Hypselodoris to the genus Felimare in 2012, the authors of this species argue against this decision.
