For a long time it has been considered that the whitefin gudgeon Gobio albipinnatus is the species that inhabited Tisa and Latorica Rivers. On the other hand some researchers have discussed subspecific status of these populations, concluding that they should be classified as belonging to the subspecies G. albipinnatus vladykovi. During the last years taxonomy of the gudgeons has been profoundly modified. It has been established that the whitefin gudgeon belongs to the genus Romanogobio, which has been lifted from subgeneric to generic level. Also a number of former subspecies or other infrasubspecific taxa of the both genera, Gobio and Romanogobio, have been recognised as valid evolutionary species. Our latest investigation based on both traditional (i.e., morphological) and molecular methods pointed out that the “whitefin gudgeon” of Tisa and Latorica Rivers is in fact Romanogobio vladykovi (Fang, 1943). Our finding confirms previous classifications of these populations to the subspecies vladykovi, that is, to the Danube whitefin gudgeon. Species status was identified by direct sequencing of mitochondrial (control region) and nuclear (S7 protein) DNA. Also morphological data strongly support such identification, however variability found in Tisa and Latorica Rivers was greater than formerly known from the literature.
