In a March 2020 article in the Zoological Journal of the Linnean Society, the authors provide a wide suite of evidence for splitting the pampas cat complex five ways.
Whether you agree with them or not I suppose depends how splitty you are versus how lumpy (and in turn often that has to do with how many you have already seen yourself), but it’s convincing enough for me to post the range maps here.
Based on their data, I made a map up that has the authors’ info and abstract, plus proposed Latin names and ranges. This has been talked about in some cat forums but I have not seen it here yet.
