First New Cat Species Discovered in 100 Years: Leopardus tilcayo
Published · Updated
Cited: National Geographic, BBC, FOX Weather
TL;DR
Scientists have confirmed a new species of wild cat, Leopardus tilcayo, from Bolivia — the first new felid in over 100 years.
Why now
The discovery, published in September 2026, reshapes the cat family tree and underscores how modern genomics can reveal hidden biodiversity even in well-studied groups.
Agree / conflict
Experts agree that small wild cats have long been understudied and that this finding likely opens the door to more discoveries in Africa and Asia.
Takeaway
This tiny spotted cat is a reminder that we still have much to learn about Earth’s species, and that every creature needs a closer look.
More than a decade ago, a Bolivian man found a tiny spotted kitten on a forest road and raised it as a pet. When the animal proved too wild to keep, it was taken to a sanctuary where biologist Paola Nogales-Ascarrunz recognized something unusual. What followed was a genetic detective story that would reveal a completely new species of cat.
The finding has forced scientists to rethink the entire tiger cat group. Where once there were three species, there are now five. Even more surprising, the same study hints that the margay, a small spotted cat ranging from Mexico to Argentina, may actually be four separate species.
FAQ
How is Leopardus tilcayo different from other tiger cats?
It is physically smaller (about 3 pounds, 18 inches long), has larger rosettes, a shorter face, and rounder ears. Genetically, it diverged from other tiger cats about 1.4 million years ago.
Where does this new cat live?
Only known from Bolivia’s Yungas forest ecoregion, on the eastern slopes of the Andes. Its exact population size is unknown.
Why was it not discovered earlier?
Small wild cats look very similar, and there were few museum specimens. The cat was often mistaken for the northern tiger cat or margay. Advanced genomic analysis was needed to confirm its unique status.
What does this mean for cat taxonomy?
The official list of living cat species (Felidae) is expected to grow from 41 to at least 44 or 45, with further splits likely in the future.
Is the new species endangered?
Conservation status has not yet been assessed, but like other tiger cats, it is likely threatened by deforestation and habitat loss. The discovery stresses the need for localized conservation efforts.
