Authority The first time the name was proposed was by M. Sars (1869), but this is a nomen nudum and unavailable because no description or illustration was provided. M. Sars died in 1869, and his work was continued by his son, G.O. Sars and the name was used again by him, this time with a proper description and illustration of both genus and species. This takes the authorship and date of the son according to the rules of the ICZN. [details]Unreviewed
