Current SSAR Comments:
See comments under A. boreas. This taxon is nested in the A. boreas group and the entire group is in need of a comprehensive revision to determine species boundaries. Key studies, e.g., Goebel et al. (2009, Molecular Phylogenetics and Evolution. 50: 209–225), Gordon et al. (2017, Zootaxa 4290: 123–139) indicate that the taxon may be nested within A. boreas sensu lato.
