We studied the historical biogeography of a group of butterflies in the Holarctic region belonging to the genus Coenonympha (Nymphalidae: Satyrinae: Coenonymphina), based on a phylogenetic hypothesis estimated from three genes. The genus is distributed mainly in the Palaearctic region, with two species extending into the Nearctic region. The tree is generally well supported and shows that Coenonympha is paraphyletic with respect to Lyela (syn.n.) and Triphysa (syn.n.), and we hence synonymize the latter two with Coenonympha. Within Coenonympha we identify three species groups, the tullia, glycerion and hero groups. The North American tullia exemplars are not sister to the Eurasian ones. A diva analysis indicates that the ancestor of the group was present in the Central Palaearctic or Central Palaeartic + Western Palaearctic or Central Palaearctic + Eastern Palaearctic. We conclude that the most likely origin of extant members of Coenonympha was in the Central Asian mountains. The tullia and hero groups started diverging in Europe following dispersal into the region. There have been two independent colonizations into Africa. The drying up of the Mediterranean during the Messinian period probably played an important role, allowing colonization into the Mediterranean islands and Africa.
