Abstract: The Central European species of Dinax Malaise, 1945 (one species), Strongylogaster Dahlbom, 1835 (seven species) and Taxonus Hartig, 1837 (three species) are surveyed and briefly diagnosed. Strongylogaster baikalensis Naito, 1990 and Dinax ermak (Zhelochovtsev, 1968) are newly recorded species for the Czech Republic. The larvae of Strongylogaster baikalensis, Taxonus sticticus (Klug, 1817), Taxonus alboscutellatus Niezabitowski, 1899 and Dinax ermak are described and illustrated for the first time and new data on their biology are provided. Identification keys for the adults and larvae of the Central European species of Strongylogaster and Taxonus are given.
