Biochemical-genetic evidence obtained by electrophoretic investigations to support reliability of the Black Sea goby fish group Ponticola nomenclature proposed by V. I. Pinchuk (1976, 1977, 1991): 5 species (Neogobius syrtnan, N. ratan, N. cephalargoides, N. platyrostris, N. kessleri) and 3 subspecies (N. p. platyrostris, N. p. eurycephalus, N. p. odessicus) names. In some species myogene polymorphism, in one case superoxiddismutase polymorphism have been found, explained by gene introgression as a result of occasional crossing.
