Abstract

Abstract A remarkable new species, Pampasatyrus karri sp.n. is described from the upper valley of the river Pampas on the border of the departments of Apurímac and Ayacucho in the central Andes of Peru. It occurs in grassland puna on rocky slopes around 3500 m a.s.l. It is characterized by bright golden wing uppersides, a colour unique among the Satyrinae. It is only the third known Andean representatives of this, otherwise predominantly low to mid elevation genus associated with Brazilian and Argentinian pampa, and is most closely related, as indicated by COI data and male genitalia, to P. gorkyi found 200 km south-eastwards in Cuzco. Its discovery extends the northern range limit of the genus Pampasatyrus in the Andes.
