Review of late Pleistocene and Holocene localities of insects from the North Western Siberia and the Urals

The paper generalizes the sub-fossil insect data from the 29 localities dated by the Late Pleistocene and Holocene, situated in the Northern part of West Siberia Plain and adjacent territories (the Urals and Bolshezemelskaya tundra). Based on the paleontological data, we try to reconstruct the development of entomofaunas during the Late Pleistocene and Holocene (130 thousand years ago). The dynamics of insect faunas corresponds to the main stages of development of the natural communities of this region, reconstructed on the basis of paleobotanical data. In particular, we described sub-fossil insect faunas with warm climate markers (such as ground beetles Trechus secalis ) for the Last (Eemian) interglacial period (130-115 thousand years ago). It is possible that some boreal beetle species ( Cychrus caraboides, Chlaenius costualtus ) changed their areas northwards in comparison with their modern distribution. Subsequent cooling (until the beginning of the Holocene, about 10 thousand years ago) caused the occurrence of cryophilic (arctic, tundra and subarctic) insects...
