Distribution of Promops davisoni Thomas, 1921 (Chiroptera: Molossidae) in Peru with a new record and southward range extension

Promops davisoni  is a poorly known insectivorous bat represented by fewer than two dozen specimens in collections. These species are endemic from the Andean western slopes of Ecuador and Peru where it is known from the Mongoya River, province of Manabi, central Ecuador to the Santuario Nacional Lagunas de Mejia, Arequipa department, southwestern Peru. We report a new record of P. davisoni  from Pampa Alta, Tacna department, Peru. This new specimen documents a 125 km range extension and the southernmost record of P. davisoni  from Peru.
