【 摘 要 】

The ophiuroids collected during the Oceanographic Expedition PUCK (SONNE-156) in 2001, in the framework of the project "Interactions between productivity and environment along the Chilean continental shelf" were analyzed. Eight samples had ophiuroids; Fifteen species were distributed in the following families: Gorgonocephalidae (2), Asteronychidae (2), Ophiomyxidae (1), Ophiacanthidae (2), Ophiuridae (5), Amphiuridae (1), and Ophiolepididae (2). Four species were recorded for the first time from Chilean waters, i.e., Asteronyx loveni Müller & Troschel, Astrodia tenuispina Verrill, Ophiolimna bairdi (Lyman), and Ophiocten amitinum Lyman, and three are new, i.e., Ophiura (Ophiuroglypha) arntzi sp. nov., Amphiophiura gallardoi sp. nov., and Stegophiura wilhelmi sp. nov.
