New localities of Abax carinatus on Polish lowlands are presented. Although the species is usually considered as a montane one, we found it for the first time in three Polish lowland regions: the Pomeranian Lake District, Mazovian Lowland and Podlasie. In the light of these findings Abax carinatus should be considered simply a forest species rather than a montane one. From the perspective of Polish findings we also analyse the occurrence of Abax carinatus on lowlands in the neighbouring countries.
