Geothermal springs are known to harbor unusual assemblages of dragonflies and damselflies worldwide. A review of original records and the body of available literature revealed that 27 Odonata species were recorded from hot springs in Russia so far and that the successful larval development in geothermal environments was discovered for 17 species. Among them, four species exclusively inhabit hot springs, i.e. Mnais costalis, Anotogaster sieboldii, Orthetrum melania (Kunashir Island), and O. albistylum (Eastern Siberia). In Russia, these southern species are unable to develop beyond geothermally heated water bodies due to cold climate, and they exist as local geothermal populations there. Here, we report on several novel records of Odonata species from geothermal springs in eastern Russia. Four species were recorded on the Kunashir Island (Kurile Archipelago): Mnais costalis (adults), Anotogaster sieboldii (adults and larvae), Orthetrum melania (adults), and Sympetrum pedemontanum elatum (adults and larvae). Two species were found in the Kamchatka Peninsula, i.e. Libellula quadrimaculata (freshly emerged imago and exuvia) and Aeshna juncea (larvae). To explain the origin of isolated geothermal populations of Odonata, three alternative hypotheses can be proposed as follows: (1) pre-glacial relicts; (2) mid-Holocene relicts (since the Holocene Climate Optimum); and (3) recent (late Holocene) populations founded by long-distance dispersal events. These scenarios are yet to be tested by means of a molecular approach.
