Fig. 2 Neighbour-joining phenogram calculated with the program PHYLIP ver. 3.5.c. (Felsenstein 1993), based on Nei's (1972) genetic distances for all samples analysed. The tree topology assigned the samples into the following six main clusters (from left to right): Erebia tyndarus (Central Alps), Erebia c. neleus (Balkans and Retezat), Erebia ottomana (Balkans), Erebia c. cassioides (eastern Alps with Apennines), Erebia c. arvernensis (western Alps, Pyrenees, Massif Central and Passo Maghen located in the south-eastern Alps) and Erebia nivalis (eastern Alps). Bootstrap values calculated with 1000 permutations are given for values exceeding 50 % probability
