2 weeks ago I had the pleasure of being in the Jaguarland/La Moneda Reserve in Bolivia. There are quite a few tripreports of this place now on this website. I saw a lot of good stuff but one mammal had us puzzled. It seemed to resemble Agouti the closest, but it was much smaller and also moved differently. In my experience agouti’s tend to ‘hop’ while this one just ran straight with no hopping involved. The animal ran 2 times across the path and the second time I managed to get 2 (bad) pictures). I am hoping though that they might show enough of the animals distinctive shape that an ID would be possible. It seems to have a relatively large pointy head with a broad nose and distinctive ears. I would estimate it to be around 30cm.
I leafed through the ancient guide to the Neotropical Rainforest Mammals and only one type of mammal seemed to fit quite well which were the Agouchy’s. I could not find anything else that came close. The only problem is that neither one has seems to have been recorded in Bolivia with the closest one to the area a single record in Mato Grosso in Brazil of a Red Agoucy. Other records from southern Peru however were Green Agoucy (I found this info on this website: https://eol.org/pages/42028/maps). It could very well be that this species has been overlooked as it also seems to have been in Mato Grosso with a single very isolated record, but it would definitely stand out of course.
So I would appreciate any thoughts on the ID of this mammal!
