Description of Bradyetes paramatthei sp. nov. (Copepoda: Calanoida), a new aetideid species from the deep Pacific Ocean with notes on the genus Bradyetes
A new and rare aetideid species of the benthopelagic genus Bradyetes Farran, 1905 is described from female specimens collected near the seafloor from the abyss of the Pacific, Atlantic and Southern Oceans between 2000 and 2014. The new species, Bradyetes paramatthei sp. nov., is described from the K...
