ABSTRACT: The redescription of Gonocerca muraenolepisi Paruchin et Ljadov, 1979 was made on the specimens collected from Muraenolepis marmorata Gьnther, 1880 (Gadiformes), caught in the Ross Sea, and on extant paratypes — one of which was designated as neotype — is given in this paper. Phylogenetic relations of G. muraenolepisi were inferred by Bayesian analysis of partial sequences from 28S rDNA. Molecular data are not consistent with the traditional point of view about the position of the genus Gonocerca Manter, 1925, and subfamily Gonocercinae that are based on this genus in the family Derogenidae. Also, molecular data does not support the presence of the genus Hemipera Nicoll 1913, in the subfamily Gonocercinae. The taxonomical position and species lists of representatives of the Gonocercinae need further revision.
