Mustela haidarum

The Haida ermine was identified as a new species in 2021. It is a hybrid descendant between ancient Mustela erminea and Mustela richardsonii that started some 375,000 years ago, when the ice allowed the two species to come together. The population has established itself as a species in some islands on the Pacific Northwest of North America. This began It was previously just considered a variety of subspecies of short-tailed weasels.
The subspecies haidarum used to be known as Queen Charlotte Islands Stoat. Though since they're all subspecies anyways, I don't see what's wrong with the distinction. It's still the same animal. They're from the Haida Gwai archipelago. It is considered to belong to Canada. Celenda is the Prince of Wales Island Ermine, and seclusa is the Suemez Island ermine.
The Haida and Tlingit tribes were the ones who encountered these ermines the most. The Haida would have lived with the Haida ermine and the Suemez Island Ermine, while the Tlingit would have lived with the Prince of Wales Island Ermine. However, as they visited and traded with each other both would have encountered all of these animals.
