Quick Summary

Scientists have identified a new species of wild cat called "tilcayo" in Bolivia's cloud forests, marking the first discovery of a living feline species in over 100 years. The tilcayo measures 46cm long and weighs about 1.4kg, with distinct light brown fur featuring irregular rosettes. Researchers used DNA analysis from samples across South America to confirm that tiger cats actually consist of five genetically distinct species, including the newly identified Leopardus tilcayo and a new subspecies in Peru's Yungas forest named Leopardus tigrinus antisuyo.
