Abstract – New report on Sturnira aratathomasi diet and some notes on its distribution in Colombia . The natural history and distribution of many bat species is still unknown, especially for those restricted to mountain environments. A genus with most of its species found in the Andes is Sturnira, been Sturnira aratathomasi the largest in the genus but also a species whose biology and ecology is poorly known. Here we report for the first time, a fruit consumed by this species and we review its distribution. A study of the bat assemblage was carried out in a humid montane forest in the Central Andes of Colombia and fecal samples were collected to compare them with a plant reference built for this study. Five individuals of Sturnira aratathomasi were captured and two fecal samples were collected with seeds from Solanum sycophanta Dunal 1852, a tree found in mature and early secondary forests. This finding corroborates the strong association between the genus Sturnira and the Solanaceae family. A literary review of the species was carried out and geographical coordinates were obtained, plotted afterwards on geographical information system map of South America and Colombia. The distribution of Sturnira aratathomasi , with an emphasis in Colombia, confirms that it is restricted to habitats over 1650m and associated to Andean forests. Comments on other reports are made.
