Remarks: It is remarkable that both taxa H. giresunus and H. glacialis are said to occur side by side in two provinces ( Erzurum , Hakkâri ). Errors in older determinations cannot be completely ruled out here. To answer this question, females will have to be compared. Distribution: Has a disjunctive range in high mountain locations ( 1500–2100 m ) of the Pyrenees, Alps, the Balkans and Asia Minor . Turkey : Erzurum , Hakkâri ( Fig. 17 .II).
