Bibimys labiosus Winge, 1887 (Mammalia: Rodentia: Sigmodontinae): New records in Paraná state, southern Brazil, and update of the known geographic distribution

Abstract

Bibimys is a genus still poorly known in its basic aspects, such as systematics, natural history and geographic distribution. In Brazil, only Bibimys labiosus is recorded, with occasional records spread in time and space. This paper presents four new localities of the species in Araucaria Forest, Parana state, extending its distribution 150 km southwards. Additionally, a map of the known distribution of the species in Brazil and in Araucaria Forest is provided. The records point toward the lack of knowledge about basic aspects of the small nonflying mammal fauna in the plateau regions of Brazil.
