The steppe specialist butterfly Proterebia afra (Lepidoptera: Nymphalidae: Satyrinae) inhabits both the continental Palaearctic steppe biome and southern mountain steppes, it occurs as a relic on the Balkan Peninsula. Based on molecular markers and species distribution modelling, we analysed its historical biogeography. In the assumed ancestral range (northern Iran and southern Caucasus), the populations form distinct units, which probably differentiated during downhill–uphill shifts during the Pleistocene glacial cycles. Populations north and east of the Caucasus Mountains form a single lineage, separated from the southern populations for the entire Plio-Pleistocene. This lineage retained a contiguous distribution during glacial maxima, documenting that this steppe species inhabited vast areas during glacial times. The Balkan populations are distinct, revealing in situ survival within glacial cycles. The connection between the south-eastern Balkans and the Black Sea surroundings could had been lost in relatively recent times, owing to human-induced changes in land use.
