The Southern Ocean harbours rich deep-sea ecosystems with local hotspots of benthic biodiversity. Still, many species, including deep-water octocorals, remain undescribed despite the fact that the exploration of the deep-sea has improved thanks to recent technological advances. In this context, a new species of golden gorgonian has been collected at 1407–1581 m depth during a recent cruise to Dronning Maud Land in the Eastern Weddell Sea. Currently, after recent changes in Chrysogorgia taxonomy, Chrysogorgia lunae sp. nov. (Octocorallia: Scleralcyonacea) is the only known representative of the genus in Antarctic waters. It corresponds to the "Squamosae typicae" and is characterized by a bushy colony with branching sequence of 2/5L and bell-shaped polyps. A molecular comparison with published sequences of Chrysogorgia species is provided based on a concatenated sequence of two mitochondrial genes, mtMutS and COI, as well as the 28S nuclear ribosomal gene. |
