Calypsophontodes gen. nov. (Copepoda: Harpacticoida: Ancorabolidae), a New Genus of Laophontodinae, Including Remarks on Ancorabolid Phylogeny
Both sexes of Laophontodes macropodia Gee and Fleeger, 1986 (Ancorabolidae, Laophontodinae) are redescribed in detail based on type material from the South Orkney Islands and other material from King George Island (South Shetland Islands). The species is fixed as the type of a new genus Calypsophont...
