A review of the ground beetle fauna (Coleoptera: Carabidae) of the Tambov Region

Based on published sources and original data, an annotated checklist of ground beetles of the Tambov Region was compiled, comprising 250 species belonging to 57 genera. The highest species richness was recorded in the genera Amara (30 species), Harpalus (29), Bembidion (25), Pterostichus (16), Agonum (15), Carabus (14), and Ophonus (8). The ground beetle fauna of the Tambov Region is typical of the central part of European Russia. The proportion of species shared with the fauna of the Tambov Region in neighboring regional faunas increases from north to south and ranges from 76.2% to 83.2%. High faunal similarity is observed for the Voronezh and Saratov Regions, which border the Tambov Region to the south, as well as for the Lipetsk Region, located at the same latitude. In regions situated further north, the proportion of shared species gradually decreases. Four species were identified as dominant; three of them – Carabus granulatus Linnaeus, 1758, Harpalus rufipes (De Geer, 1774), and Pterostichus melanarius (Illiger, 1798) – are eurybionts with wide geographic distributions and high ecological tolerance, occurring across a broad range of habitats.
