Mammals of the Valle del Cuna Piru Reserve, Misiones, Argentina. Here we present the results of surveys conducted at the Reserva Privada de Usos Multiples Valle del Cuna Piru (Misiones, Argentina) with the objective to assess the diversity of mammals in this area. The study area is placed at the middle part of the course of arroyo Cuna Piru, near Aristobulo del Valle, where phytogeographical com- munities of Selvas Mixtas and Campos districts intermix, both belonging to the Upper Parana Atlantic Forest. Nine field works allowed us to register 58 native and three exotic species, included in 24 families and 10 orders. The richnest recorded families were Cricetidae (11 species) and Didelphidae (7 species); the bats were under-represented due to methodological samping bias. Typical species of open environments from southern Misiones and northern Corrientes, such as Cavia aperea, Lutreolina crassicaudata, and Necromys lasiurus, were recorded only in cultivated fields and fragmented patches of natural grasslands. We propose that Myrmecophaga tridactyla and Pteronura brasiliensis should be considered as extirpated from this area. The mammals constitute an important food resource for local aboriginal groups that inhabit the reserve (Mbya communities),
