Abstract

Some larval stages of the Amphionides reynaudii are identified, only representative of the Order Amphionidacea are registed for the first time for Chilean oceanic waters. The specimens were collected during the development of the cruises to the Chilean oceanic islands, in a transect between Caldera and Easter Island (spring 1999) and Juan Fernandez archipelago and Desventuradas Islands (spring 2000). The presence of this order of crustaceans in the waters of the southeastern Pacific ocean is discussed and an identification key for their recognition in the plankton samples is included.
