Amazon Jaguar

Amazon Jaguar was proposed as a jaguar subspecies by Reginald Innes Pocock in 1939. before later research failed to find evidence for it. Pocock also mentioned other subspecies, such as Panthera onca peruviana, but eventually, due to a lack of evidence, he accepted that Panthera onca peruviana could be the same subspecies as Panthera onca onca. In other words, the taxonomic name "Panthera onca onca" referred to a geographic group, if not subspecies, of jaguars north and west of the Amazon River, and south of Central America, including some Colombian jaguars, which was believed to include another group of jaguars, that is Panthera onca centralis.
