Description:

Largely blue, with a relatively narrow black humeral stripe, it is virtually identical to the less common Boreal Bluet.  The postocular spots are large and rounded-triangular, narrowly separated from a thin occipital bar.  Can be distinguished from Familiar Bluet by the large postocular spots and the shorter cerci.  Can be told from the Hagen's/Marsh complex by the size and shape of the postocular spots and possibly by the nearly all black S10.

Recently split from the Palearctic E. cyathegerum.
