Redescription of "Terebellides kerguelensis" stat. nov. (Polychaeta: Trichobranchidae) from Antarctic and subantarctic waters
During the Spanish Antarctic expeditions “Bentart” 1994, 1995 and 2003, a number of trichobranchid (Annelida: Polychaeta) specimens were collected and identified initially as Terebellides stroemii kerguelensis McIntosh, 1885, the only known species of the genus widely recognised as valid in Antarcti...
