Abstract： The DNA barcoding technique has recently been the subject of considerable interest in taxonomy and has been widely applied to the molecular systematics of the Coleoptera. This paper summarizes the Coleopteran COI gene sequence and the application of DNA barcoding in species’ identification, discovery of cryptic and new species and phylogenetic analysis of the Coleoptera. Progress in DNA barcode technology and problems in DNA barcode standardization are discussed.
