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.Johnson R. F & Gosliner T. M. (2012). "Traditional taxonomic groupings mask evolutionary history: A molecular phylogeny and new classification of the chromodorid nudibranchs". PLoS One 7: e33479.
Distribution This species was described from Pointe sur baie de Baille Argent, Guadeloupe, . Distribution of Felimare fregona includes Venezuela, Puerto Rico, Virgin Islands, Curaçao, Guadeloupe and Panama.
