 As this was realized, the brassy ringlets of the Alps and Pyrenees were united in "E. tyndarus", either as a superspecies or as a species.In recent times, this question has been restudied, including the DNA sequence data available nowadays.The view that only a single species of this non-migratory butterfly with restricted habitat preferences occurs in far-flung localities like the Sierra Nevada of southern Spain or the Julian Alps of Slovenia is generally considered obsolete.
