New records of Glironia venusta and Didelphis albiventris (Didelphimorphia) from Peru. We report a new record of Glironia venusta from Peru. The new locality is the fifth record for the country, and the 18th for all of South America. Also, we extend the distribution of Didelphis albiventris to the Amazon Basin of northeastern Peru. The addition of these species to the biota of Iquitos reaffirm that this is one of the localities having the most species-rich marsupial fauna in the New World.

Noteworthy records of bats (Chiroptera) from Paraguay

, , , ,

Two years of extensive sampling in Paraguay, as well as the comparison of the newly collected material with specimens deposited in museums, revealed the presence of three previously unrecorded species of bats in Paraguay: Tonatia brasiliense, Chiroderma doriae, Natalus stramineus, and Histiotus macrotus. Additionally, exact localities documenting the presence of Diaemus youngi in Paraguay are documented for the first time. The sudden appearance and abundance of this species in Paraguay may be the result of increasing livestock activities in the area.

Importantes registros de murciélagos (Chiroptera) de Paraguay. Dos años de colecta intensiva de pequeños mamíferos en territorio paraguayo, así como la comparación del nuevo material con ejemplares de museo, ha permitido reconocer la presencia en Paraguay de tres especies de murciélagos no reportadas previamente: Tonatia brasiliense, Chiroderma doriae, Natalus stramineus e Histiotus macrotus. Asimismo, se documenta por primera vez de manera exacta la presencia de Diaemus youngi en Paraguay. La aparentemente súbita aparición y abundancia de esta especie en el Chaco paraguayo puede ser resultado del incremento en las actividades pecuarias en el área.
