Interesting observations of beetles (Coleoptera) from Kaliningradskaya Oblast during 2018–2019, with supplementary pre-2018 data

Abstract

30 Coleoptera species are recorded from Kaliningradskaya Oblast, Russia. Ten species are reported for the first time, one of which, Leiopus femoratus, is expanding the areal from long distance, and two, Phaleria cadaverina and Trachys fragariae, from short range; four species, Lopheros rubens, Isorhipis marmottani, Ischnomera cyanea and Anaesthetis testacea, are probably aborigine with a cryptic habit of life, and three species, Suphrodytes figuratus, Hydrobius rottenbergii and Cotaster cf. cuneipennis, are newly named for the region as a result of recent generic revisions. Representatives of Typhaeus and Combocerus, previously known by sporadic records during the 19th century are recorded, and T. typhoeus, Ph. cadaverina and C. cf. cuneipennis are registered in the Baltic region on the northeastern limit of the areal.
