Abstract
Seven shallow-water colonial ascidians of the order Aplousobranchia, including three new species, are identified in the material collected by SCUBA divers off the coast of Central Chile. Three species including Aplidium falclandicum, A. fuegiense and Didemnum studeri were known previously from Subantarctic and South Chile. The range of one species, Distaplia arnbackae n. sp., extends to south to Guaitecas Islands, and the rest three species (Aplidium peruvianum, Aplidiopsis chilensis n. sp. and Eudistoma clivosum n. sp.) are not known from more southern localities and may represent a northern component.References
