A new primnoid genus (Anthozoa: Octocorallia) from the Southern Ocean
A new primnoid genus is here proposed based on the study of the type material of Primnoella gracilis Molander, 1929 and the abundant material collected during some recent Antarctic and Subantarctic cruises. The new genus, Arntzia, is compared with its closest primnoid genera, mainly Ainigmaptilon De...
