Figure 4: The Bayesian tree of intercepted cerambycids based on COI barcodes.

Genera are displayed in different colors. Letters in parentheses denote subfamilies: Le: Lepturinae; S: Spondylidinae; La: Lamiinae; C: Cerambycinae. Novel DNA barcodes are highlighted in red. Inconclusive specimens are shown in grey. Note that the specimens of Arhopalus that were intercepted in the present study comprise two divergent groups, clustering with Spondylidinae and Cerambycinae. Chrysomelidae (Chrysomela populi and Cryptocephalus distinguendus) was used as the outgroup.
