Résumé : International audience
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 Ad,lie, 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.

Résumé : Seven new fish species have been found so far on the Pacific and Atlantic hydrothermal vents: the synaphobranchid Thermobiotes mytilogeiton; the zoarcid Thermarces cerberus and Pachycara thermophilum; the bythitid Bythites hollisi; the cyclopterid Careproctus hyaleius; one zoarcid fish; and one ophidiid fish. The characteristics of the 70 specimens collected, and their location in French and American museums, are listed. The results and observations made on vent fishes and fishes living around the periphery of the vents observed during recent dives (especially along the East Pacific Rise between 17 and 19 degrees S, the North Fiji Basin Rise and the Mid Atlantic Rise) are summarized. Previous literature on vent fishes is reviewed.
