Over the period of 1991-2012 a total of 1,415 adult specimens of longhorn beetles were collected during 54 field trips to the territory of the Đerdap National Park (eastern Serbia). Most specimens were caught at Tekija, in the vicinity of the village of Miroč (Mt. Miroč), Donji Milanovac, and Kazan - Ploče, while a somewhat lower number was registered at sites in Kladovo, Golubac, Liškovac, Dobra, and Mt. Miroč (with no precise sublocality). The specimens were mostly collected by hand and entomological net, but a significant number of specimens were collected by wine and pitfall traps, a mercury-containing light bulb, and rearing. Several different sites were investigated in the studied area, including meadows, forest clearings, dense deciduous forest, numerous woodpiles, and cut trunks of deciduous trees. Altogether 104 species and 43 subspecies from 55 genera, 31 tribes, and six subfamilies of longhorn beetles were found to inhabit the investigated locality. The highest number of species and subspecies is registered within the subfamilies Cerambycinae (40 species and 16 subspecies), Lepturinae (32 species and 15 subspecies), and Lamiinae (27 species and 11 subspecies). One longhorn beetle species is cited as new for eastern Serbia. Data from eastern Serbia are recorded for seven species for the second time. Twenty-nine cerambycid species are recognized as rare in Serbia. A single subspecies is Balkan endemic. Thirty-six species are recorded for the first time for the Đerdap National Park. Seven species and two subspecies are protected both nationally and internationally. The cerambycids of eastern Serbia have been insufficiently studied until now and additional investigations are necessary in the area studied
