Original Paper


A new genus and species of deep-sea eelpout (Zoarcidae), Barbapellis pterygalces, is herein described from a single adult female specimen carrying eggs and measuring 204 mm in total length. It was collected on the eastern Antarctic continental slope, off Terre Adélie, at ca. 1,200 m depth, on muddy bottom. Barbapellis is placed in the subfamily Gymnelinae and can be distinguished from all other genera by morphological characters unusual in zoarcids as well as by molecular barcoding. The genus is characterized by the presence of a complex system of cephalic skin crests and flaps, especially well developed around the mouth. A new terminology is proposed for the eleven crests and sevenfolds described. The skin folds may be used for foraging on muddy sea bottoms. The genus is also characterized by large, flexible, and highly palmate pectoral fins. The designation of the new genus is discussed.

We thank the crew and participants of the cruises involved in the capture of the samples, and especially the chief scientists of the cruise of the Census of Antarctic Marine Life-Cooperative East Antarctic Marine Census project (CAML-CEAMARC). The CAML-CEAMARC cruises of R/V Aurora Australis and TS Umitaka maru (IPY project No. 53) were supported by the Australian Antarctic Division, the Japanese Science Foundation, the French polar institute IPEV (ICOTA and REVOLTA programs), the Centre National de la Recherche Scientifique, the Muséum national d’Histoire naturelle, and the Agence Nationale de la Recherche (White Project ANTFLOCKs USAR No. 07-BLAN-0213-01 directed by Guillaume Lecointre). This project is a contribution to the EBA-SCAR program. We thank William T. White for the English revision of the manuscript, Romain Causse for his help with the map, Guy Duhamel for bibliographic references, and Mélyne Hautecœur for X-rays.
