Laetmonice iocasica sp. nov., a new polychaete species (Annelida: Aphroditidae) from seamounts in the tropical Western Pacific, with remarks on L. producta Grube, 1877
Laetmonice Kinberg, 1856 is a remarkable genus characterized by having harpoon notochaetae in the polychaete family Aphroditidae. We describe a new species of Laetmonice, Laetmonice iocasica sp. nov., found from seamounts on the Caroline Ridge in the tropical Western Pacific. The new species is read...
