Abstract

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.
