On Some Opisthobranchs from Florida

Eleven species of opisthobranchs from Florida are treated. Bosellia marcusi and Trapania dalva are species new for science. Cylindrobulla ulla Marcus, 1970, is the type-species of the new genus Ascobulla and new for North America. Ercolania funerea, Elysia ornata, E. clena, Discodoris mortenseni, Trinchesia perca, and Berghia verrucicornis are recorded from Florida. Doto chica is discussed. Several species have their names changed due to recent work of Baba and Hamatani, Habe, Tardy, Edmunds, and Marcus. These are “Acteon” punctostriatus, now Rictaxis punctostriatus, “Stiliger” funereus, now Ercolania funerea, “Catriona” perca, now Trinchesia perca, and Berghia “coerulea,” now B. verrucicornis.
