Комплексы жесткокрылых из четвертичных отложений р. Кизиха - самые южные позднеплейстоценовые насекомые Западно-Сибирской равнины

Two sites with insect remains were found in an exposure on the bank of Kizikha river, in the Rubtsovskii District of the Altaiskii Krai of Russia, Kizikha-1 with radiocarbon age 13455±150 14C BP (SPb-1347), and Kizikha-2 with the age 26094±400 14C BP (SPb-1418). This period is coincides with Sartan stadial and Kargin interstadial (MIS 2 and MIS 3). This is the southernmost late Pleistocene insect bearing deposit found in West Siberia. The fragments in both sites are represented mainly by Coleoptera. Beetle fauna from the site Kizikha-1 is represented by 34 species from 9 families. The majority of fragments belong to weevils and ground beetles. 28 species from 8 families are found in Kizikha-2 site, the majority of fragments belong to Carabidae. 7 species found in the sites, Dyschiriodes rufimanus, Cymindis cf. rostowtzowi (Carabidae), Cidnopus cf. parallelus, Pristilophus punctatissimus (Elateridae), Hemitrichapion alexsandri (Brentidae), Paophilus albilaterus and Otiorhynchus sushkini (Curculionidae), are recorded in Pleistocene deposits for the first time. Sub-fossil insect assemblages of the two sites coincides with the late Pleistocene “Otiorhynchus-type” sub-fossil insect fauna from southeastern part of West-Siberian Plain (Zinovyev, 2011; Legalov et al., 2016) with characteristics as follows: dominance of steppe species, presence of halophile species, lack of forest species. Most of these species are absent in the contemporary regional fauna. The complex of eastern species and presence of endemics of Altai-Sayan Mountain system is also characteristic to the both studied sites. Specifics of the deposit assemblages in comparison with the other late Pleistocene fauna of West Siberian Plain is in high share of meadow species that could be explained by taphonomic condition of sedimentation or microclimatic conditions caused by close location to Altai mountains. Analysis of sub-fossil insect fragments showed that open landscapes with zonal steppe and sparse meadow vegetation near rivers and in depressions were typical for this area. In comparison to contemporary conditions climate was dry and cold, but Kizikha-2 (end of MIS 3) was formed in more mild climate conditions than Kizikha-1 (end of MIS 2). Results gained from Kizikha-1 and Kizikha-2 sites are complementing data on latitudinal-zonal distribution of beetles found in late Pleistocene deposits in West Siberian Plain

First records of sub-fossil insects from Quaternary deposits in the southeastern part of West Siberia, Russia

Data are presented on species composition in Bun'kovo taphocoenosis at the Chik River, Novosibirsk, Russia (55°03′46″ N, 82°29′50″ E) with conventional radiocarbon dating ca 11,550 ± 125 14C BP. The entomofauna complex is unique by species composition. 90 species of Coleoptera from 15 families, 4 species from 3 families of Hymenoptera (Pamphiliidae, Formicidae, Sphecidae) and pupae of Diptera are recorded. Amongst Coleoptera the most numerous is Curculionidae represented with 41 species, especially Otiorhynchus – 10 species and Stephanocleonus – 8 species, Carabidae – 21 species and Chrysomelidae – 7 species. Among the species recorded, Otiorhynchus karkaralensis (Curculionidae) predominates with 250 specimens present. 80% of the species are not known for this territory at the present time. Species typical of open landscapes such as boggy tundra, cold northern and warm southern steppes are included in the taphocoenosis. Forest species are rare, and humid thermophilic species are completely absent. The Bun'kovo taphocoenosis is closely related to entomofaunal complexes found in older deposits (28,000–24,000 BP) in central part of West Siberia and the Urals based on species composition, but differs in the abundance of Stephanocleonus. Similar-age taphocoenosis from central and northern parts of West Siberia are contrasted with Bun'kovo, highlighting the absence of xerophilic species. Based on the beetle species composition, cold and dry climate conditions (at least 4–5 C° cooler than present) and prevalence of dry tundra-steppe landscapes are re-constructed at Bun'kovo. This conclusion is reinforced by palynological data from nearby sites in the southern part of West Siberia. Analysis of modern distribution ranges of the species found in the taphocoenosis shows that species have shifted dramatically from the late Pleistocene to present time because of increasing warmth and humidity during the Holocene. The contemporary distributions include shifts to the north in meso-hygrophilous and mesophilous species, to the east or south in xerophilous species, and to northern, eastern or southern directions in hygrophilous species. © 2015 Elsevier Ltd and INQUAWe are grateful to S.
