Scientists have identified a previously unknown tiger cat species in Bolivia, marking the first new living feline species formally described in more than a century. Named Leopardus tilcayo, the small spotted cat lives in the cloud-covered Yungas forests on the eastern slopes of the Andes. Genetic analysis showed that the animal is distinct from other tiger cats and separated from related lineages about 1.4 million years ago.The research also identified a new tiger cat subspecies in Peru, adding to the known diversity of South American wildlife. Scientists say the discovery highlights both the biodiversity of Latin America and the conservation challenges facing the Yungas ecosystem.Why Is This Tiger Cat Important?The discovery is significant because tiger cats were long treated as a single species, although genetic research had suggested greater diversity. Researchers analysed DNA from 38 cats from several South American countries, including museum specimens, and found five distinct tiger cat species. The findings were published in Current Biology.The new species is scientifically named Leopardus tilcayo.It lives in Bolivia's Yungas cloud forest.The cat is about 46 centimetres long and weighs around 1.4 kilograms.Genetic evidence places its separation from related tiger cats at about 1.4 million years ago.A separate tiger cat subspecies was also identified in Peru's Yungas region.Discovery In Bolivia’s Yungas ForestThe Tilcayo is a small, light-brown wild cat with irregular dark rosettes across its body. It is smaller than an average domestic cat and has been observed in the mountainous Yungas forest, a biodiversity-rich area where the Andes meet the Amazon region. Local communities had already used the name “Tilcayo” for the animal.Researchers first became interested in one animal after its appearance did not match existing descriptions of known tiger cats. The cat had previously been mistaken for a domestic animal and was later taken to a wildlife refuge. Further genetic testing helped establish that it represented a previously unrecognised species rather than a known tiger cat population.Genetic Research Changes ClassificationThe research provides a clearer picture of South America's tiger cats, which are considered cryptic species because their physical differences can be difficult to identify. DNA analysis of 38 specimens helped researchers separate the group into five genetically distinct species, including the newly described Bolivian cat.Scientists currently have limited information about Leopardus tilcayo. Camera-trap observations suggest it may be more active at night, while remains found in scat indicate that small rodents could be part of its diet. Researchers have shared their findings with the International Union for Conservation of Nature as conservation assessments of the newly separated lineages are considered.Key HighlightsLeopardus tilcayo is the newly described Bolivian tiger cat.The species was found in the Yungas cloud forests.Scientists used genetic analysis to confirm its distinct identity.Its lineage separated from related tiger cats about 1.4 million years ago.Researchers also identified a new tiger cat subspecies in Peru.Habitat loss, including deforestation and mining, creates conservation concerns in the region.ConclusionThe identification of Leopardus tilcayo shows that significant discoveries remain possible even among relatively well-studied groups of mammals. The Bolivian tiger cat had been known locally, but modern genetic research was needed to establish its scientific status. Researchers now need more information about its population, behaviour and habitat requirements. Protecting the Yungas forests could also become increasingly important as scientists reassess the conservation needs of individual tiger cat species.Disclaimer: This article is provided for news and knowledge purposes only.
