A new data on the fauna of Coleoptera of the Lower Volga and the Middle Don regions (Volgograd and Astrakhan Regions, Kalmykia) are given on the basis of author's research during 2014-2019. Taphoxenus goliath Faldermann, 1836 (Carabidae) is recorded for the fauna of Russia for the first time. Three species, Acinopus picipes Olivier, 1795, Dinodes decipiens (Dufour, 1820) (Carabidae), Agrilus planipennis Fairmaire, 1888 (Buprestidae) (an invasive species, which is included in the list of quarantine objects of Russia) are listed for the Lower Volga region for the first time. Acinopus laevigatus Ménétriés, 1832 is firstly listed for the Lower Volga and the Middle Don regions, and Oedesis caucasicus (Dejean, 1831) is the first record for the Middle Don (within Volgograd Region). Harpalus hospes Sturm, 1818 is a rare species, which was known from the Lower Volga region only on one specimen and was collected here the second time. Upis ceramboides (Linnaeus, 1758) (Tenebrionidae) was found in the most southern part of the range (the first record for Volgograd Region).
