[email protected] Abstract. A systematic analysis of the geographic variation of both valve shape and wing pattern reveals that the subspecies ofErebia euryale can be clustered into three groups, characterised by their valve shape. The adyte-group comprises the Alpine ssp. adyte and the Apenninian brutiorum, the euryale-group in- cludes the Alpine subspecies isarica and ocellaris, and all remaining extra- Alpine occurrences. The third group (kunz/-group), not recognised hitherto, is confined to a restricted, entirely Italian, part of the south- ern Alps. It comprises two subspecies: ssp. pseudoadyte (ssp. n.), hardly distinguishable from ssp. adyte by its wing pattern, and ssp. kunzi, strongly melanistic and even exceeding ssp. ocellaris in this respect. The ssp. pseudoadyte territory is surrounded by the valleys of the rivers Adda, Rio Trafoi and Adige, and ssp. kunzi inhabits the eastern Venetian pre-Alps, the Feltre Alps and the Pale di San Martino. The interven- ing region (the western Venetian pre-Alps, the Cima d'Asta group and the Lagorai chain) is inhabited by intermediate populations.
