ABSTRACT: Redescription and phylogenetic position of the Silvan Mouse Akodon sylvanus (Rodentia: Cricetidae: Sigmodontinae). Recent field work conducted near the type locality of Akodon sylvanus provided new specimens of this poorly known form. In this paper we provide a phylogenetic hypothesis that for the first time includes A. sylvanus. Phylogenetic and morphologic analyses show that A. sylvanus represents a valid biological species, different from A. azarae and A. pervalens, two taxa at times considered as part of the same biological species that A. sylvanus. Furthermore, our analysis suggest that A.Akodon sylvanus (Rodentia: Cricetidae: Sigmodontinae).

Furthermore, our analysis suggest that A.A. sylvanus. Furthermore, our analysis suggest that A. sylvanus belong to the A. boliviensis species group. We present an emended diagnosis ofbelong to the A. boliviensis species group. We present an emended diagnosis of A. sylvanus, which includes morphological (quanti- and qualitative analyses) and molecular (cyt b sequences) data. Finally, we summarize its known distribution, adding several new recording localities in the Argentinean provinces of Jujuy and Salta, and provide data on its natural history., which includes morphological (quanti- and qualitative analyses) and molecular (cyt b sequences) data.
