Taxonomy Large species of Elysia feeding on Bryopsis spp. were described from the tropical Pacific and placed in the synonymy of Elysia ornata (Swainson, 1840) by Jensen (1992). Both have a black band along the parapodial edge and a submarginal orange band similar to those of E. ornata. The first species, E. grandifolia (Kelaart, 1858), was described from Sri Lanka as having black and gold marginal lines along parapodia that fused with the tail (Kelaart 1858). The second species, E. marginata (Pease, 1871) was originally described from the Hawaiian Islands and subsequently from Tahiti as having a white band between the orange and black marginal bands (Pease 1871). Authorities subsequently debated whether E.grandifolia had denticulate teeth (Eliot 1904, 1908; O’Donoghue 1932). Both E. marginata and E. grandifolia were synonymized with E. ornata based on morphological comparisons between Pacific and Caribbean material (Ev. Marcus 1980; Heller & Thompson 1983; Jensen 1992).
Recent integrative taxonomic work revealed that the E. marginata-grandifolia complex contained four candidate species in Pacific, all distinct from each other and from E. ornata by (1) molecular sequence analyses of two genetic loci; (2) external features including color of rhinophores and marginal bands, folding of parapodia into siphonal openings, tail shape, and pattern of dorsal vessels; and (3) color and pattern of ECY (Krug et al. 2013). Elysia ornata is therefore restricted to the Caribbean, and some related Pacific species await formal description. [details]
