SUMMARY. Biochemical, genetic, cytometric and morphological analyses of spined loaches of the middle stream of Severskiy Donetz river revealed 3 bisexual species: Cobitis taenia s.l. (68 % of the sample); C. melanoleuca (11 %); Sabanejewia aurata (9 %) and 2 hybrid forms: triploid C. taenia(2)–sp. (9 %) and diploid C. taenia–melanoleuca (3 %). Distinctive features of genetic structure of polyploid hybrids C. taenia(2)–sp. as well as taxonomic identity of diploid C. taenia s.l. of Severskiy Donetz river were discussed in regard to the Dnieper population ones.
