Maximum likelihood tree of the Co1 sequences of the Nordic Gymnocheta spp. and related Ernestiini. Numbers at nodes indicate posterior probabilities and scale bar the relative sequence divergence. BOLD progress ID given before the species name and sample ID as well as GenBank access number given after it. The DNA barcodes do not differ between the Nordic G. zhelochovtsevi and G. viridis (BOLD:ACA6555) but differ significantly from G. lucida (BOLD:ACF3891) and G. magna (BOLD:ACA9848).
