Maximum-likelihood tree using partial nucleotide sequences from the COI gene. Clones from different continents are color coded: South Island, New Zealand (red), Asia (dark green), South America (blue), North America (black), Europe (pink), and Greenland (light green). The codes following each sample are accession numbers from GenBank or Sequence Read Archive. We used geographical location and quotation markers to describe clones without clear lineage identification (i.e., D. “pulicaria,” China).
