New wild cat species discovered - with only one known living member

A spotted wildcat from Bolivia’s Yungas forest has been confirmed as a new species, Leopardus tilcayo, after DNA analysis showed it does not belong to any previously known tiger‑cat lineage. The discovery centers on a single ten‑year‑old individual, nicknamed “Tigrino,” housed at a Bolivian rescue sanctuary; the cat was first rescued as a presumed domestic kitten before its unusual markings and behavior prompted further investigation. Lead researcher Paola Nogales‑Ascarrunz of Universidad Mayor de San Andrés, who noticed the animal’s distinct appearance while volunteering, collaborated with international scientists to sequence its genome and compare it with museum specimens, ultimately establishing the cat as the sole confirmed living member of a previously unrecognized species.

The finding expands the recognized diversity of South‑American tiger cats from three to five species, underscoring how little is known about these small, elusive felines that range from Costa Rica to Argentina. Geneticist Eduardo Eizirik explained that the lack of museum records and photographs had allowed the species to remain hidden, while co‑author Caroline Sartor emphasized that accurate taxonomy is essential for conservation planning. Tiger cats are already classified as vulnerable due to deforestation, habitat fragmentation and illegal hunting, and the new species had been omitted from prior threat assessments, highlighting a gap in protection measures for a group that receives far less public attention than larger felids.

The broader implications extend to the entire Felidae family, which currently lists 41 recognized species; the addition of Leopardus tilcayo raises that count to at least 44. Experts such as Andrew Kitchener note that the taxonomic confusion surrounding tiger cats stems from their similar spot patterns and scarce specimens, making genetic tools vital for disentangling their relationships. The discovery is expected to stimulate further field surveys in under‑studied regions, potentially revealing more undiscovered populations and informing strategies to safeguard these cats before they disappear.
