Abstract

Since 2007, the ArcticNet and CHOne programmes have allowed researchers, through oceanographic surveys on the ‘NGCC Amundsen’, to collect yearly benthic samples in the Canadian High Arctic. From the Beaufort Sea to the Bay of Baffin, more than 262 samples have been collected and analysed to provide essential data to explain patterns of biodiversity in the Canadian Arctic archipelago. Whereas common species are well known, other more rare species belonging to a few minute species groups, with debatable taxonomy, were set aside for further analyses. Focusing on Syllidae (Annelida, Polychaeta), we found and describe here Streptospinigera niuqtuut sp. nov. from muddy habitats of bathyal Arctic and continental slope beds of northern Atlantic coasts of United States between depths of 169 and 707 m. S. niuqtuut differs from congeneric species by unique dorsal simple chaetae of 1–5 chaetigers dorsally curved and distally rounded, with some sub-distal serration. This species may have frequently been reported from the region as Syllides longocirrata Ørsted 1845 but in fact are species of the genus Streptospinigera Kudenov 1983. We also transfer Streptosyllis templadoi San Martín 1984 to this genus and provide herein a key for the identification of all species of the genus.

Notes

Acknowledgments

The authors deeply appreciate the assistance and support of the crew of the Canadian Coast Guard icebreaker CCGS Amundsen and several other people for technical support during the fieldwork, especially V. Roy and A. Fontaine. We also thank H. Link for collecting and providing 2008 samples and people from the ‘Laboratoire d’Ecologie Benthique’ of ISMER (L. de Montety and L. Tréau de Coeli) for sorting and setting aside Syllid specimens. We kindly acknowledge A. Robar and P. Snelgrove for providing additional material from recent surveys in the Gulf of Maine (USA). We also thank C. Grant for her help in the preparation of the map of the S niuqtuut distribution, E. Rodríguez (SIDI, UAM) for help with the SEM pictures and T. Meziane, curator of the MNHN Polychaete collection. We are also grateful to J. Nogueira and two anonymous referees for their constructive comments about the first version of this manuscript and to C. McKindsey for improving the English. This study benefited from a 2-year secondment of first author at the ISMER/UQAR provided by the MNHN and was financially supported by ArcticNet, the Canadian Healthy Oceans Network (CHONe), the Natural Sciences and Engineering Research Council of Canada and Québec-Océan.
