New Tiger-Cat Species Unveiled in Bolivia’s Cloud Forests
By Drooid · · How we work
Core Event
Scientists have formally described Leopardus tilcayo, a tiny spotted wild cat from Bolivia’s Yungas cloud forest, as a new living feline species. The discovery was published in *Current Biology* (online September 17, 2026) and announced publicly on September 18, 2026. It is the first new wild-cat species named since the Uruguayan pampas cat in 1923.
Background & Context
The animal entered scientific attention when a local man rescued a kitten in 2016 and handed it to the Senda Verde Wildlife Sanctuary in 2017. Biologist Paola Nogales-Ascarrunz noted the coat pattern did not match known tiger-cat descriptions. DNA work led by Nogales-Ascarrunz with geneticist Eduardo Eizirik and evolutionary biologist Jonas Lescroart compared whole genomes from 38 Leopardus specimens—including eight museum samples—from across South America. The analysis revealed five genetically distinct lineages within the tiger-cat complex, one of which is the newly named Leopardus tilcayo.
Data & Statistics
- Size: head-body length ? 46 cm; tail ? 25 cm; weight ? 1.4 kg.
- Genetic divergence: split from other tiger cats about 1.4 million years ago.
- Sample set: genomes of 38 individuals plus DNA from eight historic specimens.
- Known individuals: only two live specimens have been examined—a ~10-year-old male (“Tigrino”) in captivity and a female released after rescue.
Why It Matters / Impact
Reclassifying tiger cats into five species reshapes conservation priorities. Each lineage now occupies a more restricted range, requiring separate population assessments. The Yungas forest, threatened by deforestation, mining, agriculture and wildfires, is the sole confirmed habitat for L. tilcayo. Researchers warn the species could be classified as endangered once evaluated by the IUCN.
Official Statements & Responses
Researchers emphasized that the discovery shows how much biodiversity remains undocumented. Nogales-Ascarrunz called the find “a remarkable event” and highlighted the need to protect the Yungas forests. Sanctuary co-founder Marcelo Levy said the cat has become an “ambassador for conservation.” The authors have submitted their findings to the IUCN for a separate assessment of each tiger-cat lineage.
On-the-Ground Reports
When AP reporters visited the sanctuary, the male cat emerged briefly, sniffed the air and retreated to foliage, illustrating its stress-prone nature. Staff keep the animal out of public view to minimize disturbance.
Conflicting Reports & Gaps
*Population size, exact distribution, and ecological habits remain unknown.* Only two individuals have been studied directly, and camera-trap records are limited. Researchers acknowledge that “our information at this moment is limited to the two live individuals that we examined, and a small number of camera-trap records” (Lescroart).
Verbatim Quotes
- “Its fur is light brown ... with irregularly shaped rosettes across its body,” — Paola Nogales-Ascarrunz
- “We never expected this ?Bolivian tiger cat to be a separate species, and no one had ever proposed it as a different animal, subspecies or otherwise,” — Jonas Lescroart
- “Showing the general public that even in a flagship group such as cats ... there are still new species to be discovered may transmit an important message,” — Eduardo Eizirik
What’s Next
The team is installing additional camera traps across the Yungas to locate more individuals and map the species’ range. They plan to submit a formal IUCN assessment for Leopardus tilcayo and its Peruvian counterpart, Leopardus tigrinus antisuyo, and continue genomic work to identify other cryptic cat species in South America.
