Taxonomy

Radulinus was first proposed as a monospecific genus in 1890 by the American ichthyologist Charles Henry Gilbert^[1]when he described the slim sculpin (R. asprellus) from waters off the "northwestern U.S.A.".^[2] The 5th edition of Fishes of the World classifies the genus Artediellus within the subfamily Cottinae of the family Cottidae,^[3] however, other authors classify the genus within the subfamily Radulininae of the family Psychrolutidae.^[1]
