| Abstract: | A genus and species of Antarctic benthic hydroids new to science, Mixoscyphus antarcticus gen. nov., sp. nov., is described and figured. Its systematic position amongst allied genera of the family Sertulariidae
is discussed. The studied material originates from the South Shetland Islands area (West Antarctica), which was collected
by several Spanish and US Antarctic expeditions. Mixoscyphus gen. nov. currently represents the only complete endemic genus of Antarctic benthic hydrozoans. A discussion of other genera
of benthic hydroids that are largely endemic to the Antarctic is also provided. |
