A new locality in Paraguay for the Black-tailed Marmoset, Mico melanurus (Geoffroy Saint-Hilaire, 1812) (Primates, Callitrichidae)

Abstract

Mico melanurus is an endangered primate in Paraguay, with most Paraguayan records in the vicinity of Agua Dulce (Defensores del Chaco National Park). We report the first well-documented locality outside of the Agua Dulce/ Linea 1 transect, representing the most northeastern record in Paraguay, as well as a new habitat for the species, transitional Pantanal-Cerrado. This note demonstrates the importance of monitoring areas which have been insufficiently studied for conservation purposes.
