Abstrakt:	The nucleotide sequences of mitochondrial genome fragments containing the genes coding for cytochrome oxidase subunit III (COIII) and 12S ribosomal RNA of common European viper and Nikolsky’s viper from various habitats (Saratov, Samara, and Penza oblasts; Chuvash Republic; and the Republic of Mordovia) were determined. According to the sequencing data, all samples clustered into two groups except for a number of individuals carrying single mutations in the genes in question. One group comprised V. nikolskii from Saratov oblast and the other, V. berus from the Chuvash Republic, Republic of Mordovia, and Samara and Penza oblasts. These results comply with the available data on the karyotypes of the studied vipers of this region. Further genetic studies of V. nikolskii and V. berus from various parts of this area are necessary. [ABSTRACT FROM AUTHOR]
