In Bolivia, a new cat species identified— first in over a century, Pg4

Key Highlights:

• A new wild cat species, Leopardus tilcayo, has been identified in Bolivia's Yungas forest.
• This discovery marks the first formal naming of a new living cat species in over a century.
• Researchers used genetic data to confirm its distinctness, publishing their findings in the journal Current Biology.
• The cat, locally known as Tilcayo, is smaller than an average domestic cat, measuring about 18 inches long and weighing around 1.4 kg.

Detailed Insights:

• The newly identified species belongs to a group known as tiger cats, found across much of South America.
• Its fur is light brown with irregularly shaped rosettes across its body, as described by Paola Nogales-Ascarrunz.
• Genetic analysis of 38 cat samples from various South American countries revealed that tiger cats comprise five genetically distinct species.
• The lineage of Leopardus tilcayo separated from other tiger cats approximately 1.4 million years ago.
• The Yungas forest is a mountainous region characterized by frequent cloud cover and high humidity.
• Limited information suggests its diet includes small rodents, and camera-trap evidence indicates it may be more active at night.

Scientific/Technical Concepts Involved:

• Cryptic species: Species that are morphologically similar and difficult to distinguish by appearance but are genetically distinct.
• Genetic data/analysis: The use of DNA sequencing and other molecular techniques to study evolutionary relationships and identify distinct species.
• Cloud forest: A type of tropical or subtropical moist forest characterized by persistent, frequent, or seasonal low-level cloud cover, often found in mountainous regions.
