Scientists have made a historic breakthrough in the South American cloud forests, identifying a new living feline species for the first time in more than a century.
The newly named wild cat, known locally as the tilcayo, has been officially classified as Leopardus tilcayo. Discovered in the lush, humid Yungas forest of Bolivia, this miniature predator is smaller than an average house cat, measuring just 46 centimetres long and weighing a mere 1.4 kilograms.
Unmasking a Cryptic Species
For decades, scientists grouped various wild felines across South America under the umbrella term "tiger cats." However, because these cats are "cryptic species"—meaning they look almost identical to the untrained eye—their distinct genetic identities remained hidden.
The breakthrough came when an international team of researchers analyzed DNA from 38 cats across South America. The genetic data revealed a staggering truth: tiger cats are actually five entirely distinct species.
According to evolutionary biologist Jonas Lescroart, the tilcayo's genetic lineage separated from other tiger cats roughly 1.4 million years ago, a massive temporal gap that firmly establishes it as a unique species.
A Shadowy Lifestyle
Because the species is so new to science, much of its lifestyle remains a mystery. Researchers studying the cat at the Senda Verde wildlife sanctuary—home to one of only two live individuals examined—have pieced together early clues:
-
Diet: Analysis of scat samples suggests they primarily hunt small rodents.
-
Activity: Camera-trap data indicates they are predominantly nocturnal.
-
Appearance: They sport a light brown coat adorned with irregular, distinct rosettes.
The study also identified another new subspecies in Peru’s Yungas region, named Leopardus tigrinus antisuyo.
Disappearing Before Discovery
While the discovery has thrilled the scientific community, it has also sparked urgent warnings. The Yungas mountain forest is one of Bolivia's most threatened ecosystems, facing intense pressure from deforestation, agriculture, mining, and human-caused wildfires.
Currently, the International Union for Conservation of Nature (IUCN) lists tiger cats broadly as "vulnerable." However, researchers fear that when the tilcayo is assessed on its own, its tiny population and fragmented habitat will instantly qualify it as endangered.
"There are many undiscovered species out there in the world," warned senior study author Eduardo Eizirik, "and they are at risk of disappearing before we even discover them."
