Lesser Grisons, Galictis cuja
I visited Argentina for an hour or two in 2009, when I popped over the border from Brazil at the Iguazu Falls, and saw many Brazilian Cavies and Coatis plus some Brown Capuchins. I visited again, for a week of work and mammals, in June 2017 and spent a weekend in Entre Ríos province. And I was back in September 2018 to spend 3 days on the Valdes Peninsula.
