The paper reports the results of a study of ground beetles of the Lesser Kuril Chain for 2012-2022. The total number of Carabidae on the islands is 80 species from 33 genera and 18 tribes. Among them 76 species are known from Shikotan, 28 from Polonsky, 24 from Yuri, 26 from Tanfiliev, 7 from Anuchin and 1 from Zeleny. Of these, 2 taxa ( Carabus opaculus kurosawai Breuning, 1957 and Badister lacertosus sasajii Morita, 2001) were indicated for the first time for the fauna of Russia; 4 species ( Carabus tuberculosus Dejean, 1829, Bembidion lucillum Bates, 1883, Agonum gracile Sturm, 1824 and Amara ussuriensis Lutshnik, 1935) for the first time for the fauna of the Lesser Kuril Chain; 1 species a first for Shikotan Island; 15 species a first for Tanfiliev Island; 1 species is a first for Anuchin Island. The paper also discusses the features of current fauna of ground beetles of the Lesser Kuril Chain. It is noted that the following historical events played a major role in its formation: a) the absence of volcanic activity in the Pleistocene-Holocene time; b) cooling of the Earth’s climate during the Pleistocene era; c) warming in the Holocene climatic optimum about 8-5 thousand years ago; d) anthropogenic influence, most clearly manifested in the late 20th/ early 21st century.
