title: The spermatozoa structure peculiarities of the subgenus Sumeriomys (Rodentia, Arvicolinae, Microtus)
abstract: Owing to distinct differences in size and shape in different taxa, spermatozoa can be of a high diagnostic value. The functional and evolutionary nature of such diversity is poorly understood. The purpose of the study was to summarize the data on the differences in sperm design and linear parameters between the subgenera Sumeriomys and Microtus (the genus Microtus) and to carry out the same comparison between the "socialis" and "guentheri" groups of species within the subgenus Sumeriomys.
