This paper presents morphological data for Brazilian specimens of two sacoglossan species (Elysia subornata and Oxynoe antillarum), including color photos of living animals, scanning electronic microscope pictures of radula and penis morphology. Elysia subornata is characterized mainly by its papillose body and a very elongated renopericardial ridge. The variation found in body color and tooth morphology, as well as the wide geographical distribution attributed to this species, may be indicative of a species complex. Oxynoe antillarum is a light green species covered by small white dots which resembles Oxynoe azuropunctata, but in the latter the patches of the body are larger and more conspicuous. The material studied herein represents the first record of the order Sacoglossa in the state of Rio de Janeiro, Brazil.
