In this study,we present an assessment of the evolutionary history and phylogenetic relationships of asian mountain voles of the subgenus Aschizomys,genus Alticola,based on extensive sampling and phylogenetic analyses of data from mitochondrial and nuclear *** species of this subgenus are widespread in the mountain areas of north-eastern ***,both their distribution and taxonomic borders remained questionable for more than 100 *** study showed discordance in the phylogenetic patterns between nuclear and mtDNA *** found that mtDNA in *** is paraphyletic relative to ***,but nuclear markers demonstrated reciprocal *** to species distribution modeling,ranges of *** and *** experienced a secondary contact during the Last Glacial Maximum(approximately 22 kyr BP),and thus a hybridization event seems plausible during that *** tree analyses recovered a sister group relationship between the two species of the Aschizomys subgenus,with an estimated divergence date of around 0.8 *** results provided good support for currently recognized subspecies within both *** and *** based on mitochondrial and nuclear datasets.A new,yet undescribed form,supposedly of a subspecific status within ***,was found in the Bureinskiy Range in the Khabarovsk *** finding expands the current species distribution range further to the southeast.
