Phylogenetic results by Händeler et al. (2009) indicate that the Caribbean "Bosellia marcusi" described by Eveline Agnes du Bois-Reymond Marcus (1972) is a derived species of Elysia. Morphological examination indicates that the parapodia of "B. marcusi" have secondarily fused over the dorsum, producing a superficial similarity with Bosellia. Bosellia marcusi Marcus, 1972 is a synonym for Elysia marcusi (Marcus, 1972).
