Description

Four species of shell-less marine gastropods, col­lectively called "sea slugs", are newly recorded from outlets of estuarine systems, the Paranaguá estuarine complex and Guaratuba Bay, on the coast of Paraná state. These include a marine pulmonate slug, Onchidella indolens (Gould, 1852) (Eu­pulmonata: Systellommatophora: Onchidellidae); two species of sea hares, Bursatella leachii de Blainville, 1817 (Euthyneu­ra: Sacoglossa: Aplysiidae) and Elysia serca Er. Marcus, 1955 (Euthyneura: Sacoglossa: Plakobranchidae); and one species of nudibranch, Spurilla braziliana MacFarland, 1909 (Nudi­pleura: Aeolidiidae). Egg mass shapes of E. serca and B. leachii are newly described.
