- Аннотация: We examined a cranial morphometric data set consisting of 186 specimens from the entire distribution range of Ochotona pallasii sensu lato and O. argentata, as well as 67 complete sequences of the COI gene and 28 sequences of the MGF and PRKCI introns from these and closely allied species. Our results show that the two allopatric morphologically similar taxa composing O. pallasii sensu lato – from Mongolia and adjacent territories and Kazakhstan – are paraphyletic relative to O. argentata. Genetic distances between these three taxa are larger than the intraspecific variation known for the subgenus Pika, in which the species under consideration belong; these distances are even larger than the interspecific differences among closely related species such as O. hyperborea, O. mantchurica and O. hoffmanni. Thus, the three focal taxa are recognized here as distinct species. Inspection of the type specimen of O. pallasii indicated that this specimen was not collected in Kazakhstan, has previously been theorized. The most probable place of the holotype’s origin is Russian south-eastern Altai (Chuyskaya Steppe); whatever its exact origin, it definitively originates from the ‘Mongolian’ taxon. Based on this evidence, the senior synonym for the Kazakh pika is O. opaca Argyropulo, 1930. Thus, we propose to recognize three separate species in the O. pallasii species group: O. pallasii (Mongolia and adjacent territories), O. opaca (eastern Kazakhstan) and O. argentata (Helan Shan Range, China).
