In the Magellan region, Ascidiacea appear to be a dominant invertebrate group at depths from 5 – 20 m. Most of the present collection, made by scuba divers in the Strait of Magellan, have a geographic range limited to Patagonia, the Falkland Islands, South Georgia, the South Shetland Islands and north of the Antarctic Peninsula. The exceptions are two circumpolar species: Distaplia cylindrica (Lesson, 1830) and Didemnum studeri Hartmeyer, 1911. One new species is described.
