FAUNA COMPOSITION AND KNOWLEDGE ABOUT THE VARIEGATED MUD-LOVING BEETLES (COLEOPTERA: HETEROCERIDAE) OF RUSSIA

Zoogeographical features of 22 species ranges of variegate mud-loving beetles (Coleoptera: Heteroceridae), recorded from the territory of Russia are analyzed. All species are divided by the macroregions of Russia. Was eight types of species range is recognised, taking into account longitudinal and latitudinal characteristics. The fauna of Russia is allochthonous with the absence of endemism. The main “donor” of the Russian fauna is the Tethys desert-steppe region. The species richness of zonal faunas increases from north to south. From west to east (after the Ural), a significant decrease in the species richness of Heteroceridae is observed in Western Siberia, and its re-increase in Eastern Siberia and the Far East with the inclusion of East Tethysian and East Asian elements.
