title: [Supraspecies relationships in the subfamily (Rodentia, Cricetidae, Arvicolinae): unexpexted result of nuclear genes analysis].
abstract: Phylogenetic analysis of supraspecies relationships in one of the most young and species rich group of myomorph rodents - subfamily Arvicolinae was carried out on the base of two nuclear genes. Results have shown that mole-voles - Ellobiusini, steppe voles - (Lagurini) and grey voles (Arvicolini) are sister groups. This divergence is the most late, third wave of radiation within the family. The sister clade to this group is the tribe of red-back voles - Myodini (=Clethrionomini) - "second radiation". The order of divergence for earliest radiation remains still unresolved (Ondatrini, Prometheomyini, Dicrostonychini, Lemmini). New data on the close relationships of mole voles, grey voles and steppe voles are unexpected one and contradict to the conventional views. The latter ideas on the significant ancientry and separation of Ellobiusini from all other voles is based on extreme simplicity of their rooted molars and very peculiar structure of the skull and postcranial skeleton. However, many of these characters most likely indicate on significant degree of adaptation to the subterranean life and have no phylogenetic signal.
