Concept Reference: Turgeon, J., R. Stoks, R.A. Thum, J.M. Brown, and M.A. PcPeek. 2005. Simultaneous Quaternary radiations of three damselfly clades across the holarctic. The American Naturalist 165(4): 78-107.
Concept Reference Code: A05TUR01EHUS
Name Used in Concept Reference: Enallagma annexum
Taxonomic Comments: This genus is in need of thorough taxonomic and phylogenetic study; some of the subgroups may deserve taxonomic recognition (Westfall and May, 1996). All new World populations of Enallagma cyathigerum now considered distinct from Old World populations; New World populations now placed under Enallagma annexum (still common name Northern Bluet), while Old World populations maintained under Enallagma cyathigerum (Turgeon et al., 2005).
