A new housecat-sized feline species has been discovered in Brazil.
Oncillas are housecat-size felines found throughout much of South America, and are also known as little tiger cats, little spotted cats or tigrinas. But not all oncillas are the same: New research suggests that little tiger cats in northeastern Brazil belong to a different species from those elsewhere on the continent, although they look virtually identical.
Researchers analyzed the genetic material of oncillas in northeastern Brazil, and compared them with nearby populations in the south. They found that there was no flow of genes between the two populations of oncillas, and hasn’t been any for millennia, according to the study, published today (Nov. 27) in the journal Current Biology.
This, along with other genetic differences, led researchers to conclude the two populations do not interbreed and are in fact different species, said study co-author Eduardo Eizirik, a researcher at Pontifical Catholic University of Rio Grande do Sul in Brazil.
