Abstract
The infraorder Zoarcales (Cottoidei), or eelpouts, includes about 400 species of coldwater fishes concentrated mainly in the North Pacific. To date, the molecular phylogenetic methods in combination with morphological data have significantly contributed to understanding the taxonomic composition of this group and made it possible to confirm/refute validity of some families of obscure origin. In spite of the growing amount of new data on taxonomy and evolution of eelpouts, a consideration of the original and independent data is obviously needed to verify the existing knowledge of this taxon. In this study, which is based on concatenated matrix of Co-1 and Cyt-b mitochondrial genes, as well as relying on the samples from seven families and 45 species of eelpouts, we have reconstructed the phylogeny, which is generally consistent with previous inferences. Despite the resolution of the original data matrix is low, we have demonstrated the monophyletic origin of the families Zoarcidae and Anarhichadidae, as well as Neozoarcidae, previously related to Stichaeidae and recently revised Eulophiidae. The polyphyletic patterns amongst some subfamilies in Stichaeidae have been confirmed, whereas Opisthocentrinae and Pholidae seem to constitute a valid family-level taxon. Our results provide new opportunities with respect to taxonomic relationships in the complex and diverse group of eelpouts, whose part in the tree of life is not covered by recently flourishing multilocus phylogeny of teleost fishes. In light of the data obtained, the necessity of more unified and reproducible approaches to resolve the issues of evolution and taxonomy of such a complex group as Zoarcales becomes more evident.
