Identification, taxonomy, and variation. Cliff Ferris (pers. comm.) stated this subspecies may be a redecoration of the form known as S. hesperis nikias (which has since been synonymized under S. hesperis electa by Scott et al. 1998). Adult wingspan is on average 60 mm.

Forms of this subspecies may have been referred to as Speyeria hesperis [ atlantis ] electa (Edwards) [= Argynnis Cornelia Edwards ], S. hesperis [ atlantis ] nikias (Hermann) , or Speyeria hesperis [ atlantis ] hesperis (Edwards) in the past. See the synonymies for these taxa.
