Resum
Most biodiversity studies of eastern Pacific octocorals have focused on the tropical shallow waters from Mexico to Peru, and more recently, on those off Chile. The first description of a Chilean octocoral dates back to the H.M.S. Challenger expedition (1873–1876), and since then, only a few descriptions of new coral species have been published from this region. In addition, the taxonomic status of most gorgonians reported from the temperate Pacific coast of South America remains uncertain due to the loss of the original type material. In this study, we use morphological characters and nuclear and mitochondrial markers to re-evaluate the taxonomy of the Chilean gorgonians Phycogorgia fucata and Leptogorgia chilensis. Our findings support the monophyly of Chilean Leptogorgia, confirm that Leptogorgia chilensis from Chile is distinct from specimens identified as the same species in California, and reveal that P. fucata, despite its unique morphology, should be included in the genus Leptogorgia.
