DNA Barcode.

BOLDBIN: BOLD:AAD7664 (BIN merge with several other species, see Fig. 25). See Suppl. material 1: Table S1 for GenBank accession numbers.

Remark.

DNA barcodes for D. segnis material from Canada and Greenland were very similar to several of the seven species found in the BOLD:AAD7664BIN merge (Fig. 25) and in some cases, identical to those of D. setibasis . However, both sexes of D. segnis can easily be distinguished from all other species in this BIN by the presence of a haired anepimeron. We would therefore not recommend using COI to discriminate specimens of D. segnis from those of other species in this BIN.
