Scientists have identified a tiny wild cat in Bolivia’s cloud forests as a previously unknown species, the first new living feline species formally described in more than a century.

Named Leopardus tilcayo, or “tilcayo” by local communities, the cat lives in the Yungas forest and is smaller than an average house cat, weighing about 1.4 kilograms.

DNA analysis of 38 tiger cats from across South America revealed that the group contains five genetically distinct species, with the Bolivian cat’s lineage separating from other tiger cats about 1.4 million years ago.

Researchers say little is known about its behavior, although evidence suggests it may eat small rodents and be most active at night, Al-Jazeera has reported.

The team also identified a new tiger cat subspecies in Peru’s Yungas, highlighting the region’s previously unrecognized feline diversity.
