New and unpublished data about Bulgarian ground beetles from the tribes Pterostichini, Sphodrini and Platynini (Coleoptera, Carabidae)

Bulgarian ground beetle (Coleoptera, Carabidae) fauna is relatively well studied but there are still many species and regions in the country which are not well researched. The present study aims at complementing the data about the distribution of the carabids from the tribes Pterostichini, Sphodrini, and Platynini, containing many diverse, interesting, and endemic species. It gives new records for 67 species and 23 zoogeographical regions in Bulgaria. The material was collected in the period from 1926 to 2021 through different sampling methods. Twenty-three species are recorded for the first time in different regions. Six species are reported for the second time in the regions where they were currently collected. Thirty-one species have not been reported for more than 20 years in Eastern and Middle Stara Planina Mts., Kraishte region, Boboshevo-Simitli valley, Sandanski-Petrich valley, Lyulin Mts., Vitosha Mts., Rila Mts., Pirin Mts., Slavyanka Mts., Thracian Lowland, and Sakar-Tundzha region. New altitude ranges are established for six of the species. The results contribute to the knowledge of the Bulgarian carabid fauna. Currently, 56 species of Pterostichini, 23 species of Sphodrini, and 36 species of Platynini are known from Bulgaria.
