The biogeographic history of the Southern Ocean (SO) fauna is complex and poorly studied, especially the areas of endemism. We reanalyzed the data of Marques & Pena Cantero (2010), along with other geographical records of endemic benthic hydroids below 45oS. A Parsimony Analysis of Endemicity (PAE) based on 5o latitude by 5o longitude matrix with 61 species resulted in eight areas of endemism. We discuss these results in the context of different hypotheses of the evolution of the SO fauna and previously proposed biogeography patterns.
