I would definitely agree with David in that E. notaeus is not typically found within Uruguay, and has only been found in the extreme northwest border region of Uruguay where it has a common border with Brazil and Argentina. Definitely not found as far south as Buenos Aires. The most southern range extent of E. notaeus appears to be around the Parana River floodplain and wetlands area just south of Santa Fe, Argentina. This site appeared to be a little liberal with many of their range maps.
