Distribution range of the three alpine Coenonympha species: C. gardetta, C. macromma, and C. darwiniana. The range of the fourth species, C. arcania (everywhere in Europe at low elevation, including the valleys of the Alps) is not shown. Stars: location of contact zones C. arcania/C. macromma in Chaillol, C. arcania/C. gardetta in Vaujany and Aoste, C. arcania/C. darwiniana in Locarno, C. gardetta/C. darwiniana in Bellwald, and C. gardetta/C. macromma in Vars. Diamonds: locations of allopatric populations: C. arcania (dark red), C. gardetta (blue‐green), C. macromma (orange), and C. darwiniana (pale yellow)
