A Frequency distributions of inter and intraspecific similarities for beetle COI sequences (paired comparisons, percentage of bases/residuals that are identical for each comparison for cytochrome oxidase I (COI) sequences included in Figure 6B). B Identification of Cephaloleia kuprewiczae sp. n. and C. histrionica using cytochrome oxidase I (COI) sequences. Neighbor-joining tree includes bootstrap values (%) supporting species identifications. Filled circles represent DNA sequences obtained from adults. Empty circles represent DNA sequences obtained from larvae.
