''Cottocomephorus'' was first proposed as a monospecific genus in 1900 by the French ichthyologist Jacques Pellegrin when he described ''Cottocomephorus megalops'' as a new species.<ref name = CofF/> The genus was classified in the family Cottocomephoridae; however, the 5th edition of ''Fishes of the World'' classifies the genus within the subfamily Cottinae of the family Cottidae, studies having found that the genera formerly included in the Cottocomephoridae were a clade arising from the genus ''Cottus''.<ref name = Nelson5>{{cite book |title=Fishes of the World |edition=5th |author1=J.
