Resumen

We present a revision of distribution of Micronycteris schmidtorum in Northern South America reporting fourteen new localities of the species for Colombia and Ecuador on both sides of the Andes. We present the first records of the species for Ecuador, the first record for the biogeographic region of El Chocó, and fill the gap in Amazonian localities between Peru, Venezuela and Colombia. Finally, we determine morphometric variation of the species: Colombian specimens are larger than other Central and South American specimens and specimens of French Guiana are the smallest. We found size differentiation between cis- and trans-Andean populations in Colombia and Ecuador, apparently mediated by the Andes Cordillera.
