New Bolivian Cat Species Discovered

A small, spotted cat found in Bolivia sparked a scientific mystery that led to the proposal of a new species, Leopardus tilcayo. The animal was first noticed by biologist Paola Nogales-Ascarrunz in 2017 after a local man had taken the kitten home and cared for it for about a year. The cat’s compact face, rounded ears, long whiskers and bold leopard-like spots set it apart from ordinary housecats.

Nogales-Ascarrunz initially thought the cat was a Leopardus tigrinus, a small tiger-cat species common in Central and South America. In 2019 she compared photographs of the Bolivian cat with a reference tiger-cat image from Brazil and saw that the rosettes were noticeably larger. This prompted a genetic study with Eduardo Eizirik and Jonas Lescroart, which placed the animal as distinct enough to be a new species. The name Leopardus tilcayo comes from a traditional local name.

The discovery shows that even well-studied regions can still hide new species, and that other tilcayos may still be moving quietly in Bolivia’s misty Yungas forests.

Key takeaways

  • Leopardus tilcayo is a newly proposed species discovered in Bolivia.
  • The cat was first seen by biologist Paola Nogales-Ascarrunz in 2017.
  • Its larger rosettes and genetic data distinguished it from Leopardus tigrinus.
  • The species name derives from a local traditional name.
  • Other tilcayos may still exist in Bolivia’s Yungas forests.
