Two new species of Orbiniidae (Annelida, Polychaeta) from the Condor Seamount, Azores, NE Atlantic Ocean

Two new species of Orbiniidae (Annelida, Polychaeta) from the Condor Seamount in the NE Atlantic Ocean off the Azores are described. The first, Berkeleyia condoriensis sp. nov., is the seventh species of the genus to be described and the first from the North Atlantic Ocean. The new species is from 1006 m on the southern flank of the Condor Seamount. The second species, Microrbinia hartmanae sp. nov., is only the second species of the genus to be described, both from the North Atlantic Ocean. Like the first, M. linea Hartman, 1965, the new species has a unique dorsal glandular organ on some specimens. These organs are believed to be male copulatory organs and are unique within the family. Microrbinia hartmanae sp. nov. is from 206 m on the summit of the seamount.
