Abstract

A new genus and species of zoarcid fish, Gosztonyia antarctica, is described on the basis of four specimens collected from the Bellingshausen Sea, Antarctic Ocean, at a depth of 615 m. Gosztonyia is placed in the subfamily Lycodinae and can be distinguished from all other zoarcid genera by the following combination of characters: seven branchiostegal rays, interdigitating ceratohyal–epihyal articulation, palatal arch reduced, posterior hyomandibular ramus longer than anterior, cranium narrowed, supratemporal commisure and occipital pores absent. A new species, Gosztonyia antarctica, is described and the relationships of the new genus are discussed.
