Lista preliminar de los mamíferos (Mammalia: Theria) del departamento de Nariño, Colombia

Due to its high number of ecosystems and wide altitudinal gradient, the department of Cauca in southwestern Colombia, encloses a great part of the Colombian mammal diversity. In spite of its richness, the mammalian fauna from Cauca has been poorly studied. In order to synthesize the information on mammals from this Department, we present a checklist of 220 mammalian species that occupy the continental and marine area of Cauca, representing 45 % of mammals reported as present or potentially present in Colombia. The present work was based on national mammal collections, international museums databases, and bibliographic information. Although this work represents the most comprehensive effort in documenting the mammalian fauna of the department of Cauca, future research is necessary to increase our knowledge on the mammals of Cauca and to implement more adequate conservation policies.

Mammalia, Chiroptera, Anoura fistulata Muchhala, Mena-V & Albuja-V, 2005: distribution extension

Anoura fistulata Muchhala, Mena-V & Albuja-V, 2005 is among the rarest species of phyllostomid nectarivorous bats in Colombia, currently documented from one specimen collected on the eastern versant of the Colombian Andes in Llorente, Department of Nariño (0°490.00 N, 77°150.00 W) (Mantilla-Meluk and Baker 2008). Anoura fistulata was originally described from the Provincia Zamora Chinchipe, Condor Mirador (03°3808 S, 78°2322 W), at an elevation of 1,750 m above sea level, on the eastern side of the Andes, in Ecuador. Anoura fistulata represents one of the largest forms within the A. caudifer complex (A. aequatoris (Lönnberg, 1921), A. cadenai Mantilla-Meluk & Baker, 2006, A. caudifer (É. Geoffroy St.-Hilaire, 1818), A. fistulata, and A. luismanueli Molinari, 1994), which is composed by small-sized species with complete zygomata and well-developed uropatagium. Among Anoura species, A. fistulata is characterized by extreme morphological adaptations to nectarivory (Muchhala 2006). We report three additional records of A. fistulata for Colombia, one of them representing a geographic extension of the species by almost five degrees of latitude north of the currently northernmost known record of the species.
