The sacoglossan Elysia sp. 23 is not yet identified or still undescribed, I call it Elysia sp. 23 to distinguish it from other species of Elysia, until I know its name.
Elysia sp. 23 is caracterized by its translucent whitish-gray body, head and rhinophores. There is an opaque white line on each rhinophore. The parapodia are mottled dark gray-green/black with a distinctive black margin and a thin opaque white submarginal line.
This species is as Elysia sp. 1 in Gosliner et al. (2015) at page 83. Very similar specimens or the same species are often found at Bali, Indonesia, they differ by orange tips of the rhinophores.
