PRIMER REGISTRO DE Eumops nanus (CHIROPTERA: MOLOSSIDAE) EN OAXACA, MÉXICO

First record of Eumops nanus (Chiroptera: Molossidae) in Oaxaca, Mexico. We report the first record of Eumops nanus for the state of Oaxaca, in southern Mexico. This finding represents an extension on the distribution area for this species in Mexico. It is the first record of the Eumops genus for the Isthmus of Tehuantepec, increasing to 9 the number of Molossidae species in this region; and it is the second record in the Mexican Pacific slope after 40 years. This record is a result of searching for animal remains within a wind farm. Palabras clave: Istmo de Tehuantepec. Molossidae. Murcielago enano de bonete. Parque eolico.
