The thick forests of Bolivia harbor a fauna as rich as it is cryptic. Recently, researchers described a new feline species living there, marking the first such discovery in more than a century for these animals.<\/strong><\/p>\n

Pocket Tigers<\/strong><\/h2>\n

The American feline genus Leopardus encompasses several small cats, among them the ocelot, the margay, and the tiger cats<\/strong>. The wild nature of their habitats and the nocturnal lifestyles of these creatures have long made identification and classification difficult, and for a long time they were regarded as a single species, named Leopardus tigrinus<\/em> and listed as vulnerable by the International Union for Conservation of Nature.<\/p>\n

It wasn\u2019t until the early 2010s that genetic sequencing of these cat-sized predators, observed across a large portion of South and Central America, was carried out. While their local names and subtle physical differences had hinted at diversity for a long time, this process led to the recognition of the Southern tiger cat (L. guttulus<\/em>), L. emiliae<\/em>, and the nebulous tiger cat (L. pardinoides<\/em>) in addition to L. tigrinus tigrinus<\/em>.<\/p>\n

In a study published in the journal Current Biology<\/em>, Eduardo Eizirik of the Pontifical Catholic University of Porto Alegre and colleagues analyzed the complete genomes of 38 representatives of the genus Leopardus<\/em>, including 26 tiger cats spanning the entire known distribution, which extends from Costa Rica to the Andean regions as well as the tropical forests of eastern South America.<\/p>\n

These new sequences led to the identification of a fifth distinct species, evolving in the Bolivian Yungas on the eastern flank of the range. Measuring between 42 and 50 centimeters in length and weighing about 1.5 to 2 kilograms, Leopardus tilcayo<\/em> diverged from the lineage that includes L. tigrinus<\/em> tigrinus<\/em> and L. pardinoides<\/em> roughly 1.4 million years ago.<\/p>\n

The team also found that Peru\u2019s forests harbor a new subspecies, named L. tigrinus antisuyo<\/em>. Like L. tilcayo<\/em>, it displays the tiger-cat morphology, but with fur coloring and patterns that are noticeably different.<\/p>\n

The density of South American forest environments and the numerous natural barriers that separate them suggest that other feline species remain to be discovered. A better understanding of tiger-cat diversity will, in turn, help guide conservation efforts, as their ancestral habitats are increasingly threatened by agricultural expansion.<\/p>\n

Previously, researchers had resolved longstanding mysteries about the evolution of felines.<\/p>\n
