Abstract

A new species of Andalgalomys is described from the Monte Desert-Chacoan thorn-scrub region of Argentina. This genus previously was known in Argentina only near Andalgala, Catamarca Province, from a single isolated valley; specimens of the new species are the first documentation of the genus outside the province. Specimens from localities in Catamarca and San Luis provinces are reported. The distribution of the genus is extended southward ca. 500 km. The diploid number of chromosomes is 60.
