Freshwater nemerteans of the genus Prostoma have been frequently documented across the Russian Empire, the USSR, and the Russian Federation, but no genetically confirmed records have been made. A fragment of the cytochrome oxidase I (COI) gene was obtained from a specimen collected in the Moscow region, confirming its affiliation with the cosmopolitan species Prostoma clepsinoides Dugès, 1828. The specimen belongs to the same haplotype as the sample from Italy (KU840284.1). Currently available genetic data do not yet allow us to determine the original range of P. clepsinoides.
