Abstract: New argentinean localities for some sigmodontine rodents (Rodentia, Cricetidae). On the basis of trapping and analyses of owl pellets, we report new Argentinean recording localities for 25 sigmodontine species. These records include the first Argentinean mentions for Akodon boliviensis, Akodon cf. A. varius, and Necromys amoenus. We also present records that extend the known distribution of Akodon budini, A. sylvanus, A. toba, Necromys cf. N. lasiurus, Calomys musculinus, Loxodontomys micropus, Phyllotis osilae, P. xanthopygus, and Tapecomys wolffsohni. Finally, we report additional localities for A. illuteus, A. longipilis, Chelemys macronyx, Notiomys edwardsii, Necromys lactens, Bibimys chacoensis, Holochilus chacarius, Oecomys sp., Oryzomys angouya, O. legatus, Reithrodon auritus, Rhipidomys austrinus, and Euneomys mordax. Taken as a whole, the records presented here suggest that much work remains to be done in order to have an adequate picture of the diversity and distribution of Argentinean sigmodontines.
