The ranges of eight species [Fallenia fasciata (Fabricius, 1805), Neorhynchocephalus tauscheri (Fischer, 1812), Nemestrinus caucasicus (Fischer, 1806), N. bombiformis Portschinsky, 1892, N. brandti (Bequaert, 1938), N. laetus obscuripennis (Portschinsky, 1887), N. reticulatus Latreille, 1802, and Trichopsidea costata (Loew, 1875)] from Eastern Europe and the Caucasus are discussed. With the exception of Nemestrinus caucasicus, the other species are rare in the territory studied; their latest findings are referred to the late nineteenth and early twentieth centuries. These species should be considered as endangered species and included into the Red Data Books of the corresponding regions. N. obscuripennis (Portschinsky, 1887) is regarded as a Caucasian-Anatolian subspecies of N. laetus (Loew, 1873) basing on the study of lecto-and paratypes of the former. A key for identification of the genera and species considered is given.
