Herein we comment on the location of 8 Argentinean type localities for 22 sigmodontine taxa (Cricetidae: Sigmodontinae). This study is based on information gathered from original publications, labels of type specimens, field catalogs and notes housed in museums, and historical records and maps. These localities (arranged in order of increasing latitude) are: Higuerilla (Province of Jujuy), Caraguatay and río Paranay (Province of Misiones), río de Oro (Province of Chaco), Otro Cerro (Province of Catamarca), “Norte de Entre Ríos” (Province of Entre Ríos), Isla Ella (Province of Buenos Aires), Neuquén, río Limay (Province of Neuquén), and Valle del Lago Blanco or Valle/Región Koslowsky (Province of Chubut). We clarify the geographic location, provide current names, and/or restrict these type localities. Finally, we also pose comments on the taxonomic significance of these actions.
