Exploring the diversity of the deep sea—four new species of the amphipod genus Oedicerina described using morphological and molecular methods
Abstract Collections of the amphipod genus Oedicerina were obtained during six expeditions devoted to the study of deep-sea environments of the Pacific Ocean. The material revealed four species new to science. Two species (Oedicerina henricisp. nov. and Oedicerina teresae sp. nov.) were found at aby...
