Abstract. The invertebrate fauna of the "Balabana" and "Dolna Topchiya" managed nature reserves is studied, with particular consideration to the ground beetles. The area of study is interesting from a biological point of view, as the Tundzha River constitutes a corridor of penetration of southern and thermophilic elements. On the other hand, the specifics of the territory predetermine the presence of many typically forest and some mountain species, as well as a lot of inhabitants of open biotopes, in particular – steppe forms. During the study, altogether 2041 specimens of carabid beetles belonging to 88 species are captured, as well as 76 other invertebrate species, some of which are with a conservation significance – new, endemic, rare, protected or endangered. Forty-six carabid species are reported for the first time for the Sakar-Tundzha region. Ground beetles are characterized and classified according to their zoogeographical belonging and the life forms they refer to.
Key words: Carabidae, invertebrates, "Balabana", "Dolna Topchiya", Tundzha River, Bulgaria.
