Leopardus tilcayo: First New Wild Cat Species Discovered in Over a Century
Published · Updated
Cited: National Geographic, PBS, FOX Weather
TL;DR
4 million years ago.
Why now
The discovery was published in Current Biology on September 17, 2026, and highlights how modern genomics is uncovering hidden biodiversity even in well-studied animal groups.
Agree / conflict
While the discovery is widely celebrated, it also raises concerns: the newly recognized species likely has a smaller population than previously assumed, making it more vulnerable to deforestation and mining in Bolivia's Yungas forests.
Takeaway
This finding reminds us that nature still holds surprises—and that protecting habitats is urgent, especially for species we've only just met.
For the first time in over a century, scientists have formally described a new living wild cat species. The tiny, spotted feline, named Leopardus tilcayo, was discovered hiding in plain sight at a wildlife sanctuary in Bolivia. This breakthrough not only adds a branch to the cat family tree but also reshapes our understanding of South America's tiger cats.
The story of Leopardus tilcayo began in 2016 when a Bolivian man found a tiny spotted kitten on a roadside. Believing it to be a domestic cat, he raised it for a year before realizing its wild nature and turning it over to the Senda Verde wildlife sanctuary. Biologist Paola Nogales-Ascarrunz, a National Geographic Explorer, was called to examine the 'weird cat' and immediately noticed its unusually small size, short rounded ears, and large rosettes.
FAQ
How was Leopardus tilcayo discovered?
A man found the cat as a kitten on a road in Bolivia in 2016. He kept it for a year before giving it to a wildlife sanctuary. Biologist Paola Nogales-Ascarrunz recognized it as unusual and later led genetic studies confirming it as a new species.
Why is this discovery significant?
It is the first new living wild cat species formally described in more than 100 years. It also reveals that the tiger cat group contains at least five distinct species, not one, which has major implications for conservation.
Where does Leopardus tilcayo live?
So far, it has only been confirmed in Bolivia's Yungas forest ecoregion on the eastern slope of the Andes. Its full range is still unknown.
What does the name 'tilcayo' mean?
The name comes from local Bolivian communities who have used the word for generations. It does not appear to have a specific meaning in Spanish or Quechua.
How does this affect conservation?
Recognizing multiple species instead of one means each has a smaller population and range, increasing their vulnerability. Conservation efforts must now be reassessed for each distinct tiger cat species.
