 Genus Eolagurus

Phylogenetic evidence based on mtDNA supports the water voles of the genus Arvicola not in fact belonging to the tribe Arvicolini, but rather forming a sister group to the Lagurini. Based on the study, the Lagurini and Arvicola together form a sister group to a clade comprising Hyperacrius and the rest of the Arvicolini. References
