New Cloud-Forest Cat Species Sparks Conservation Focus in Bolivia
By Drooid · · How we work
Core Discovery
Scientists have formally described Leopardus tilcayo, a tiny spotted wild cat from Bolivia’s Yungas cloud forests, as a new living species—the first such designation in more than a century. The findings were published in *Current Biology* and are based on DNA analysis of 38 sampled tiger cats, including museum specimens. Genetic divergence suggests the Tilcayo lineage split from other tiger cats roughly 1.4 million years ago.
Background & Context
Tiger cats across South America were long treated as a single species. Decades-old genetic work hinted at hidden diversity, but the Bolivian population’s distinct morphology prompted researchers to investigate. Co-lead authors Jonas Lescroart (University of Antwerp) and Paola Nogales-Ascarrunz noted that the animal’s characteristics did not match descriptions based on Brazilian cats, leading to the hypothesis of a separate species.
Key Figures & Groups
- Paola Nogales-Ascarrunz – National Geographic Explorer, co-author.
- Jonas Lescroart – Evolutionary biologist, co-lead author.
- Marcelo Levy – Co-founder of Senda Verde Wildlife Sanctuary, caretaker of the captive individual.
- Eduardo Eizirik – Senior author, Pontifical Catholic University of Rio Grande do Sul.
- Senda Verde Wildlife Sanctuary – Private refuge near La Paz that houses the only known captive individual, nicknamed “Tigrino.”
Data & Statistics
- Size: 46 cm (18 in) from head to tail base.
- Weight: 1.4 kg (3 lb).
- Known live individuals: Two, one at Senda Verde.
- Diet evidence: Scat samples contain small rodents.
- Activity pattern: Camera-trap images suggest primarily nocturnal behavior.
Official Statements & Responses
The research team submitted their taxonomic findings to the IUCN, which currently lists tiger cats as two vulnerable species. A separate IUCN assessment is planned for the five genetically distinct lineages, including Leopardus tilcayo, which could be classified as endangered given its limited known population and the threatened status of the Yungas ecosystem. Marcelo Levy said the new species label has turned the animal into a “conservation ambassador,” raising public awareness of the need to protect Bolivia’s tropical forests.
On-the-Ground Reports
Visitors travel to Senda Verde hoping to glimpse “Tigrino.” The cat is highly stress-sensitive; caretakers keep him out of direct view, allowing only brief, supervised exposures. When the Associated Press visited, Tigrino emerged, sniffed the air, paced for a few minutes, and then retreated to foliage. The sanctuary’s growing visitor interest highlights the species’ fragility.
Conservation Implications
Researchers stress that the Yungas region faces mounting pressures from deforestation, agriculture, wildfires, and mining. Protecting remaining forest patches and restoring fire-damaged areas are urgent priorities. Eduardo Eizirik noted that showcasing a new cat species underscores how many undiscovered organisms remain at risk of disappearing before they are known.
Conflicting Reports & Gaps
Current knowledge is limited to the two examined live individuals and a modest set of camera-trap records. The authors 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.” Consequently, many aspects of the species’ ecology, population size, and distribution remain unknown.
