          Abstract

          In this study we analyze the composition of bat species of the Argentine Yungas, where 39 species have been recorded, number that indicates a high diversity of bats for the region compared with the total number of species in the country (66% of the species from Argentina). For comparative purposes we have incorporated in the analysis a revision of the species of the Bolivian Yungas. Since the mid-1970's, intensive field studies and surveys have been carried out in numerous localities of the Yungas in Argentina. The information obtained from personal collecting, plus the examination of museum specimens and literature records, allowed us to examine a total of 1682 specimens. One noctilionid, 12 phyllostomids, 13 vespertilionids, and 13 molossids were recorded in the area. For every species we include the specimens examined, additional records, distribution, reproduction and also provide additional comments related to the biology of the species observed by us during fieldwork studies. Biogeographical analyses were made considering the presence or absence of each species by degree of latitude along latitudinal gradients. The Yungas of Argentina was also compared with that of Bolivia and with other phytogeographic provinces, such as Chaco, Monte, Andean, and Paranaense regions, located at the same latitudinal range as the Yungas in Argentina.

          En el presente estudio se analiza la composición de especies de murciélagos de las Yungas de la Argentina, donde 39 especies han sido registradas, lo que indica una diversidad alta (66% de las especies de Argentina) comparada con el total de especies que habitan el país. A modo de comparación se ha analizado también las especies que habitan las Yungas de Bolivia. Desde mediados de los años '70 se han desarrollado estudios intensivos de campo a numerosas localidades de las Yungas en Argentina. A esta información se ha agregado la obtenida en colecciones científicas, con un total de 1682 ejemplares examinados, así como los registros de la literatura. Como resultado, se ha definido que las Yungas de Argentina contienen actualmente una especie de noctiliónido, 12 phyllostómidos, 13 vespertiliónidos y 13 molóssidos. Para cada especie se detallan los ejemplares examinados, registros adicionales, comentarios sobre diferentes aspectos de su biología, distribución, reproducción, y otros aspectos de interés observados durante el trabajo de campo. Se presenta un análisis de la biogeografía de las especies de las Yungas de Argentina, a lo largo de un gradiente latitudinal, comparada con las Yungas de Bolivia y también con otras unidades fitogeográficas de Argentina, como el Chaco, Monte, Puna, Región Andina y Paranaense.
