Abstract

The examination of polychaete collections obtained during the Spanish Bentart 2006 expedition to the Bellingshausen Sea (Antarctica) revealed the presence of several sphaerodorid species. In this work, species belonging to the genera Sphaerodorum Örsted, 1843, Ephesiella Chamberlin, 1919, Clavodorum Hartman and Fauchald, 1971 and Sphaerephesia Fauchald, 1972 are reported including two new species belonging to Sphaerodorum and Sphaerephesia, respectively. A specimen identified as Ephesiella sp. might also represent a new species but, due to its poor state of preservation, a formal description is not possible yet. Furthermore, Sphaerodoropsis polypapillata Hartmann-Schröder and Rosenfeldt, 1988 is transferred to the genus Clavodorum Hartman and Fauchald, 1971 after examination of the type series and specimens obtained from the Bellingshausen Sea.

Notes

Acknowledgments

The authors wish to thank Dr. A. Brandt (Zoological Museum, Hamburg) for the loan of type series of Sphaerodoropsis polypapillata. Many thanks also to A. Castro and C. Sueiro (SAIN, Universidade da Coruña) and R. Barreiro (RIAIDT, Universidade de Santiago de Compostela, Spain) who assisted with the preparation of specimens and use of the SEM, to Y. Lucas for assisting with the preparation of the drawings and to J. García-Carracedo for the translation of several bibliographic references and the revision of the English version of the manuscript. The authors are also grateful to T. Bakken, B. Ebbe and D. Eibye-Jacobsen for their constructive comments on an earlier version of the manuscript. Special thanks to the crew of R/V Hespérides and all the colleagues which collaborated in the Bentart 2006 expedition and especially to Carles San Vicente (Generalitat de Catalunya) and Patrick Arnaud (Station Marine de Endoume, France) who collected the specimens from the Epibenthic Sledge samples. The Bentart expeditions were carried out under the auspices of the Spanish Government through the Ministry of Education and Science and were supported by the Spanish Antarctic Programme (CICYT) (REN 2001-1074/ANT and CGL2004-01856).
