Abstract
Here, we present the first record of Eptesicus brasiliensis argentinus Thomas, 1920 for the province of Entre Ríos, Argentina. This subspecies was originally described as a full species (E. argentinus) based on its morphological features that clearly separate it from all other species of the genus. However, it was later treated as a subspecies of E. brasiliensis by Cabrera (1957), a treatment that was followed by all authors until today. Our record raises the number of bat species for the province of Entre Ríos to 21. This locality represents the fourth record for this subspecies in Argentina, after 35 years since the last known record was obtained. Its geographic range is extended by approximately 130 km to the south, which represents the southernmost known record for this subspecies, and a new ecoregion, the Espinal, is added to its distribution.
Highlights
Entre Ríos is one of the least studied provinces of Argentina regarding its bat fauna; its natural vegetation has been so strongly affected that, at present, it is highly fragmented due to agricultural development (De La Fuente and Suárez 2008, Calamari et al 2014)

In Argentina, 4 species of the genus Eptesicus Rafinesque, 1820 have been recorded: E. brasiliensis (Desmarest, 1819), E. chiriquinus Thomas, 1920, E. diminutus Osgood, 1915 and E. furinalis (d’Orbigny and Gervais, 1847); the last 2 species are known to have a wide distribution in the country, while E. chiriquinus and E. brasiliensis are restricted to just a few localities
Summary
Entre Ríos is one of the least studied provinces of Argentina regarding its bat fauna; its natural vegetation has been so strongly affected that, at present, it is highly fragmented due to agricultural development (De La Fuente and Suárez 2008, Calamari et al 2014). Argentinus was known to be restricted to only 3 localities in 2 provinces of Argentina (Romaña and Toranzos 1947, Massoia 1976, Barquez et al 1999): (1) Puente sobre el río Bermejo (26°20′ S, 059°21′ W) (San Martín Department, Chaco Province), (2) Estancia El Pilar, 2 km de Parada Tataré (29°08′ S, 059°15′ W) (Mercedes Department, Corrientes Province), and (3) Goya (29°00′ S, 058°19′ W) (Goya Department, Corrientes Province) (Fig. 1). Argentinus for the province of Entre Ríos, Argentina, which represents the fourth known locality for the distribution of the species in the country We here report E. b. argentinus for the province of Entre Ríos, Argentina, which represents the fourth known locality for the distribution of the species in the country
