Bathylutichthys

Bathylutichthys, the Antarctic sculpins, is a genus of marine ray-finned fishes in the family Psychrolutidae. These fishes are found in the Southern Ocean.

==Taxonomy== Bathylutichthys was first proposed as a monospecific genus in 1990 by the Russian ichthyologists Arkady Vladimirovich Balushkin and Olga Stepanovna Voskoboinikova when they described Bathylutichthys taranetzi from off South Georgia. A second species, Bathylutichthys balushkini was described by Voskoboinikova from the Meteor Shoal in the southeastern Atlantic. The 5th edition of Fishes of the World classified the genus in the monotypic family Bathylutichthyidae, but other authorities place the genus in the subfamily Psychrolutinae in the family Psychrolutidae. Phylogenetically the taxon has been argued to be intermediate between the Psychrolutidae and the two families making up the superfamily Cyclopteroidea, meaning that those two families would not be supported as a superfamily within the Cottoidei. Presently, ''Eschmeyer's Catalog of Fishes places it in the Psychrolutidae.
