Abstract： The Cerambycinae fauna of the Mongolian Plateau was investigated. A total of 69 species from 26 genera were recorded. The number of species in each genus was very different; Xylotrechus was the dominant genus, followed by Chlorophorus. Palaearctic species were the most abundant (60.87%) but widely-distributed species were also common (39.13%). The number and composition of species in each genus differed in Russia, Mongolia and China. The Palaearctic members of Xylotrechus were dominant in all three countries, Palaearctic members of Chlorophorus were dominant in Mongolia, and widely-distributed members of Chlorophorus were dominant in Russia and China. Hesperophanes heydeni Baeckm. was a new recorded species for China and four Mongolian Plateau species; Asias gobiensis Namkhaidorzh, Chlorophorus ubsanurensis Tsherepanov, Leptepania okunevi Shabliovsky, Xylotrechus pantherinus (Sav.) had not been previously recorded in China.
