A new species of nectar-feeding tailless bat in the genus Anoura (Chiroptera: Phyllostomidae) is described from the highlands of the Colombian Andes and the independent mountain system of the Sierra Nevada de Santa Marta. Complete zygomatic arches, a relatively wide uropatagium, and wide first upper molars with poorly developed paracones are proposed as synapomorphies of the new species and A. geoffroyi geoffroyi. However, the two taxa are allopatrically distributed, and the new species is morphologically distinguished from A. g. geoffroyi by a smaller skull and body size, more massive and squared molars with wider hypoconal basins, smaller P4 that are not laterally compressed, reduced anterobasal cusps, and medial internal cusps that are enlarged. Based on morphological analysis the distributional ranges of A. geoffroyi subspecies were interpreted as follows: A. g. lasiopyga is restricted to Central America from Costa Rica north to Mexico; A. g. peruana is restricted to the mid to high elevations of the Andean system from Bolivia to Colombia; and A. g. geoffroyi is restricted to the mid and low elevations of eastern versant of the Andes from Brazil to northern South America, including the island of Trinidad. Further, the morphological affinities between A. g. apolinari and members of the A. geoffroyi complex support its current recognition as a junior synonym of A. g. peruana. Based on the morphological distinction observed between A. g. peruana and A. g. geoffroyi, including the absence of complete zygomatic arches, a more delicate rostrum, less massive molars, and overall darker coat coloration, as well as the ecological differentiation of the areas inhabited by these two taxa, we recommend the elevation of A. peruana to specific level.
