Leopardus narinensis, also called the red tigrina, Nariño cat, and Galeras cat by the scientists who discovered it, is a putative species of small wild cat in the genus Leopardus . It was described in 2023, based on a single skin collected in 1989. [1]

Contents

Etymology

The specific epithet narinensis refers to the Nariño Department in southern Colombia, where the skin was collected. The proposed common names "Nariño cat" and "Galeras cat" also refer to where it was found (the Galeras volcano in the Nariño Department), while "red tigrina" refers to its markedly reddish coloring. [1]

Taxonomy and phylogeny

The skin was first collected in 1989 and donated to a Colombian national institute, which later transferred its biological collections to the Alexander von Humboldt Biological Resources Research Institute, where it remained classified as an ocelot skin until 2001, when Manuel Ruiz-García noticed it while searching for jaguar and puma specimens. He recognized it as being a different species and, when other authorities on South American cats could not identify it, spent the next two decades researching the skin. [2] The final paper was published in June of 2023. [1]

The red tigrina is classified as a member of the genus Leopardus , the small spotted cats of South America. [1]

A scientific paper published only two months later, in August 2023, considered the holotype of L. narinensis to be a specimen of L. tigrinus based on morphological comparison. [3]

Phylogeny

Genetic analyses indicate that the Nariño cat diverged from other Leopardus species about 1.3–1.0 million years ago. Both its nuclear and mitochondrial DNA are noted to be different from every known species of cat. In those genetic tests, it was consistently recovered as a sister taxon to the kodkod-Geoffroy's cat clade. [1] [2]

Characteristics

The Galeras cat is, like other tigrinas, a small spotted cat, but the base color of its fur is more reddish than in other tigrinas. The rosettes are black but with even more intensely red coloring on the inside. The top of the head and the dorsal crest are darker. The body is shorter and more robust, and the head is rounder and wider, the face flatter. The coat is denser and woollier. [1]

Distribution and habitat

The holotype and only specimen was collected from the páramo of the Galeras volcano in southern Colombia, 3,100 metres (10,200 ft) above sea level. The region has a high level of endemism due to isolation during the climatic changes at the end of the Pleistocene. [1] [2]

It has not been recorded by the camera traps that have been present in southern Colombia since 2018, and the species may already be nearly (or even totally) extinct. [1] [4]

<span class="mw-page-title-main">American lion</span> Extinct species of carnivore

Panthera atrox, better known as the American lion, also called the North American lion, or American cave lion, is an extinct pantherine cat. Panthera atrox lived in North America during the late Pleistocene epoch and the early Holocene epoch, from around 340,000 to 11,000 years ago. The species was initially described by American paleontologist Joseph Leidy in 1853 based on a fragmentary mandible (jawbone) from Mississippi; the species name ('atrox') means "savage" or "cruel". The status of the species is debated, with some mammalogists and paleontologists considering it a distinct species or a subspecies of Panthera leo, which contains living lions. However, novel genetic evidence has shown that it is instead a distinct species derived from the Eurasian cave or steppe lion, evolving after its geographic isolation in North America. Its fossils have been excavated from Alaska to Mexico. It was about 25% larger than the modern lion, making it one of the largest known felids.

It is a member of the genus Euryoryzomys, which was split off from Oryzomys in 2006. It was first described by Johann Andreas Wagner in 1848. It is found in southern Brazil, eastern Paraguay and northeastern Argentina. It is considered a large species in its genus, with a reddish-brown coat, long tail length, and large skull. It is a terrestrial rodent, spending its time foraging for seeds, fruits, and insects. It is listed by the IUCN as least concern, although studies have shown it to be influenced by anthropogenic disturbances. Predators consist of small members of the order Carnivora.

<span class="mw-page-title-main">Spotted green pigeon</span> Extinct species of bird

The spotted green pigeon or Liverpool pigeon is a species of pigeon which is most likely extinct. It was first mentioned and described in 1783 by John Latham, who had seen two specimens of unknown provenance and a drawing depicting the bird. The taxonomic relationships of the bird were long obscure, and early writers suggested many different possibilities, though the idea that it was related to the Nicobar pigeon prevailed, and it was therefore placed in the same genus, Caloenas. Today, the species is only known from a specimen kept in World Museum, Liverpool. Overlooked for much of the 20th century, it was recognised as a valid extinct species by the IUCN Red List only in 2008. It may have been native to an island somewhere in the South Pacific Ocean or the Indian Ocean, and it has been suggested that a bird referred to as titi by Tahitian islanders was this bird. In 2014, a genetic study confirmed it as a distinct species related to the Nicobar pigeon, and showed that the two were the closest relatives of the extinct dodo and Rodrigues solitaire.
