Comments.

Gyrophaena affinis is newly reported from AB based on barcoded material.

Sequenced Nearctic specimens from ON, AB, NB, and QC form a distinct barcode cluster, separate from all sequenced Palearctic specimens and divergent by 4.65%. This pattern is inconsistent with a species that is adventive in North America and we remove G. affinis from the list of adventive species in Canada. In comparing images between those of Nearctic specimens (Fig. 23B ) and those of Enushchenko and Semenov (2016) for Palaearctic specimens, there appear to be slight differences in the median lobe of the aedeagus in lateral view. In the Palaearctic illustration, the apex of the median lobe is more acute and its secondary lobe is evenly rounded at apex, while the Nearctic illustration shows a more rounded apex of the median lobe and knob-like apex of the secondary lobe (Fig. 23B ). More research is needed to determine the status of the Nearctic and Palaearctic populations, though the level of genetic divergence between discrete Nearctic and Palaearctic populations suggests that two sister species are involved.
