中文摘要：
对蒙古高原天牛亚科昆虫种类组成及区系进行初步分析，已记载共26属69种，各属所包含的天牛种类数量差异很大，以Xylotrechus为优势属，Chlorophorus次之，且在俄、蒙、中三国，各属的种类组成、数量也有差异；在种的组成中,以古北种所占比例最大，为60.87%，广布种也占有相当比例为39.13%。Xylotrechus在俄、蒙、中三国均以古北种占优势，而Chlorophorus在蒙古国以古北种占优势，在俄、中两国以广布种占优势。柽柳漠天牛Hesperophanes heydeni Baeckm.为中国新记录种。中国无分布记录的蒙古高原天牛亚科昆虫有4种:戈壁鞍背天牛Asias gobiensis Namhaidorzh、乌布苏虎天牛Chlorophorus ubsanurensis Tsherepanov、蒙瘦尾鞘天牛Leptepania okunevi Shabliovsky、阿木尔脊虎天牛Xylotrechus pantherinus (Sav.)。
英文摘要： 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.
