- Description: Whole-genome and museum-DNA evidence resolves the tiger-cat complex into five species, including the newly described Bolivian tilcayo and a new Peruvian subspecies—changing the conservation unit before population risk is even fully known.

Evidence

Peer-reviewed

Geography

South America; Bolivian and Peruvian Yungas are central to the newly described taxa

System

Neotropical cloud forests and other tiger-cat habitats

## WHAT THE EVIDENCE SAYS

A Current Biology study combined complete genomes from 38 Leopardus cats, including 26 individuals from the tiger-cat complex and historical museum material. The analysis supports five distinct tiger-cat species and describes Leopardus tilcayo from Bolivia plus a new L. tigrinus subspecies from the Peruvian Yungas. The result replaces a broad umbrella treatment with finer evolutionary units whose ranges and population sizes can differ sharply.

## WHY IT MATTERS / OUR READ

Taxonomy is operational conservation infrastructure: if several small lineages are managed under one broad species label, aggregate range and abundance can hide much narrower risks. The immediate management need is not a new intervention recipe but better lineage-specific range, population and threat data so Red List assessments and national priorities match biological units.

## CAVEATS / UNCERTAINTY

The genomic evidence is strong for lineage separation, but ecology, abundance and full distributions of the newly described taxa remain poorly known. Only a handful of live tilcayos are documented, so conservation status should not be inferred from the taxonomic result alone.
