LUTZ, M. Ayelen; DIAZ, M. Mónica; MERINO, Mariano L  and  JENSEN, Roberto F. Las especies del género Myotis (Chiroptera: Vespertilionidae) en el Bajo Delta del Paraná y la Pampa Ondulada, Argentina . Mastozool. neotrop. [online]. 2016, vol.23, n.2, pp.455-465. ISSN 0327-9383.

The genus Myotis is distributed worldwide, except at the poles. It includes more than 100 species, 12 of which are present in Argentina. Knowledge about the bats of this genus is sparse in large areas of Argentina, including the Rolling Pampa and Lower Delta of the Parana River. Here, we present a study about the species of Myotis collected in three locations: two at Islas del Ibicuy department (Entre Ríos province), and one at Parque Costero del Sur (Buenos Aires province). Morphometric data and characteristics of the collected specimens are described, providing information on intraspecific variability of each species collected in the area. We collected 51 specimens belonging to 5 species of this genus: M. albescens, M. dinellii, M. levis, M. ruber and M. riparius. The latter is recorded for first time in the provinces of Entre Ríos and Buenos Aires.
