title: Further studies of mitochondrial genome variability in Ponto-Caspian &lt;I&gt;Proterorhinus&lt;/I&gt; species (Actinopterygii: Perciformes: Gobiidae) and their taxonomic implications
abstract: Background. A new taxonomy of tubenose gobies of the genus Proterorhinus has been proposed recently. However, some of taxonomic hypotheses have not been confirmed by recent genetic studies or seem not to correspond with ecological features and genetic differentiation of these fishes. The aim of this paper was to test the new taxonomy through a phylogeographic analysis of the fish from 15 sites in Southern Ukraine and Russia, through analyzing the genotypes deposited in the GenBank and to define
