New Wild Cat Species Discovered in Bolivia After a Century

It sounds like a scene from a nature‑documentary: a modest‑sized cat, no bigger than a domestic house feline, slinking through the misty understory of Bolivia’s Yungas cloud forest. Yet this little creature, with its light‑brown fur dotted in leopard‑like spots, is not a mystery any longer. After years of living unnoticed by science, it has finally been given a name – Leopardus tilcayo – and with that name comes a splash of excitement for anyone who loves wildlife.

The story began when a local family stumbled upon the cat in the forest and, after an ill‑fated attempt to keep it as a pet, handed it over to a nearby wildlife sanctuary. The sanctuary’s volunteers, including Bolivian biologist Paola Nogales‑Ascarrunz – a National Geographic explorer and co‑author of the study – were intrigued. “He’s tiny,” Nogales‑Ascarrunz recalled, noting that the male, now about ten years old, measures just 18 inches from head to the base of his tail and weighs a scant 1.4 kg.

What made this tiny tiger‑cat stand out wasn’t just its size. Its coat pattern, a mosaic of dark spots on a sandy background, seemed oddly familiar yet distinct from known South‑American felids. To get to the bottom of it, researchers turned to genetics. By sequencing the complete genomes of more than 30 cats collected from across Colombia, Peru, Brazil and museum specimens in the U.S. and Europe, they could place the mystery animal on the feline family tree.

The DNA tells a clear story: this cat split from its nearest relatives roughly 1.4 million years ago, forming its own branch. That divergence is enough to merit recognition as a separate species – the first time scientists have formally named a new living wild cat since the pampas cat was described in 1923.

Instead of honoring a researcher, the team chose to preserve the name already used by Andean cloud‑forest communities: “tilcayo.” The resulting scientific name, Leopardus tilcayo, pays homage to the local people who have known the cat’s existence long before anyone in the academic world did.

Panthera’s wild‑cat specialist, Wai‑Ming Wong, stressed that this isn’t a brand‑new discovery in the sense of an animal never seen before. “Local communities knew it existed; science just hadn’t recognized it as distinct,” he explained via email.

The finding also helps untangle a lingering puzzle about South America’s tiger cats. For decades, many researchers lumped several look‑alike cats into a single species because their coats look so similar. The new genetic evidence now points to at least five separate lineages – four already named and the newly christened tilcayo among them.

But the work is far from over. “We still don’t know how many there are,” Nogales‑Ascarrunz admits. The cat’s range is confirmed only in Bolivia’s Yungas forests, but its full distribution, diet, breeding habits and exact habitat preferences remain mysteries awaiting field studies.

Conservationists hope that the formal recognition of L. tilcayo will act as a shield for its fragile cloud‑forest home, which faces mounting pressures from deforestation and gold‑mining. “Biodiversity is disappearing fast; we need to act quickly,” says evolutionary biologist Jonas Lescroart, another co‑author.

So, while the world may still be getting used to the name Leopardus tilcayo, one thing is clear: even in a group as well‑studied as cats, nature still has a few secrets tucked away, waiting for the right set of eyes – and a little patience – to bring them into the light.
