Five species of ground beetles are permanent inhabitants of the fumarola fields on Kunashir Island: Cicindela (Cicindela) sachalinensis A. Morawitz, 1862; Cylindera (Eugrapha) elisae (Motschulsky, 1859); Bembidion (Ocydromus) dolorosum (Motschulsky, 1860); B. (Peryphanes) sanatum Bates, 1883, and Poecilus (Poecilus) samurai (Lutshnik, 1916). These species respond differently to extreme conditions. In some species, the size is decreased (C. elisae, B. dolorosum), but is increased in P. samurai; in B. dolorosum, the pigmentation is decreased, while increased in others (C. sachalinensis, C. elisae, P. samurai). The degree of these variations depends neither on taxonomic relations nor the adaptation time. The areas of moderate thermal activity of Kunashir volcanoes could have served as refugia during the colder climatic periods. Based on data on the variability and barcoding of B. dolorosum, the following new synonymy is established: Bembidion (Ocydromus) dolorosum (Motschulsky, 1860) = Bembidion (Ocydromus) negrei Habu, 1958, syn. nov. = Bembidion (Peryphus) kuznetsovi Lafer, 2002, syn. nov.

Представлены итоги исследования Caraboidea Сихотэ-Алинского заповедника за 2015-2020 гг. Приведен список новых и редких видов жужелиц фауны заповедника, включающий 52 вида семейства Carabidae и 1 вид семейства Trachypachidae. Из них 1 вид (Bembidion asiaticum Jedlička, 1965) является новым для фауны Приморского края, 22 вида -новыми для фауны заповедника, а для 10 видов территория Сихотэ-Алинского заповедника является крайней точкой на известном ареале. В настоящее время фауна Сихотэ-Алинского заповедника насчитывает 221 вид надсемейства Caraboidea.

A revision of some Far Eastern Chlaenius species is presented. The following synonyms are proposed: Chlaenius circumductus A. Morawitz, 1862 = Chlaenius lineellus Motschulsky, 1859, syn. nov.; Chlaenius semipurpureus Motschulsky, 1865 = Chlaenius posticalis Motschulsky, 1854, syn. nov. Lectotypes of Chlaenius lineellus Motschulsky, 1859, Chlaenius semipurpureus Motschulsky, 1865 and Chlaenius hospes A. Morawitz, 1862, as well as the holotype of Chlaenius posticalis Motschulsky, 1854 are designated. Only one species of the subgenus Agostenus Fischer von Waldheim, 1829, viz. Chlaenius quadrisulcatus (Paykul, 1790), is shown to populate the Far Eastern islands of Sakhalin and Kunashir (Russia), and Hokkaido and Honshu (Japan), which is new to the fauna of the Kuril Archipelago.

Fumarole fields on the Kunashir Island are confined to the main mountain ranges formed by the Ruruy, Mendeleev and Golovnin volcanoes. Due to residual volcanism, their soil, water and air are enriched with sulfur compounds, the vegetation is strongly depressed and degraded, while the temperature of soil and subsoil air is markedly increased (Zharkov 2014). Only a few publications are specifically devoted to the fauna of fumarolic sites (Konakov 1956).Based on repeated collections in 2008 to 2018, a complex of ground beetles living in these particular conditions was revealed and studied.Among the approximately 170 species of ground beetles recorded from the Kunashir Island (Sundukov and Makarov 2016), only five appear to be permanent inhabitants of fumarole fields: Cicindela ( Cicindela) sachalinensis sachalinensis A. Mor., 1862, Cylindera (Eugrapha) elisae (Motsch., 1859), Bembidion (Ocydromus) dolorosum (Motsch., 1850), Bembidion (Peryphanes) cf. sanatum Bates, 1883 and Poecilus (Poecilus) samurai (Lutsh., 1916). Two species (C. sachalinensis and B. dolorosum) are found on all volcanoes studied, while the other species are narrowly localized. For example, C. elisae occurs on the Mendeleev and Ruruy volcanoes alone, B. cf. sanatum inhabits only the Mendeleev ‡ § ‡,|
