Dixus clypeatus (P. Rossi, 1790) (Coleoptera, Carabidae) – a new species and genus for the fauna of the western region of Ukraine // Proc. of the State Nat. Hist. Mus. - Lviv, 2025. - 41. - P. 163-172 DOI: https://doi.org/10.36885/nzdpm.2025.41.163-172 Key words: Dixus, Coleoptera, Carabidae, biodiversity, invasion, fauna, monitoring None of thes pecies of the genus Dixus Billberg, 1820 (Coleoptera, Carabidae) had previously been reported from the western region of Ukraine or the Ukrainian Carpathians. The first discovery of Dixus clypeatus Rossi, 1790 by T.P. Yanytsky (28 June 2025, Sheshory) and the second by Bohdan Fedorchak (14 August 2025, Bohorodchany) indicate the spread of the species in the Precarpathian region. Apparently, the species migrates from the south-east along the Pre-Carpathian highlands. Considering that two finds of the species were registered in 2025, it is quite likely that it is more widespread in the north-eastern foothills of the Ukrainian Carpathians, and possibly in the Prut-Dnister highland region. Only time will tell whether Dixus clypeatus Rossi, 1790 will become an invasive species, but considering that species of the genus are characterised as megathermophiles and xerophiles, as well as regional climatic, landscape features and vegetation, it is most likely that the species will settle in the most optimal local habitats for it. A key element in the control and eradication of invasive species is their monitoring or an Early Detection and Rapid Response (EDRR) system, which should be considered as a fundamental principle of effective and cost-efficient strategies for combating invasive species.
