ABSTRACTR. The article presents preliminary data on the ant fauna of the Chechen Republic (North-Eastern Caucasus), which currently includes 28 species, 15 genera, and 3 subfamilies. Formica caucasicola Seifert et Schultz, 2021 is reported as new to the fauna of Russia, and Tetramorium diomedeum Emery, 1908 is new to the fauna of both Russia and the Caucasus. Another species from the genus Lasius, currently identified only to genus level due to limited comparative material, is similar to Lasius schulzi Seifert, 1992. All species listed are recorded for the first time in the Chechen Republic.
KEY WORDS: ants, Formicidae, Chechen Republic, North-Eastern Caucasus, Russia.
