The eastern lowland olingo (Bassaricyon alleni) is a species of olingo from South America, where it is known from the lowlands east of the Andes in Bolivia, Brazil, Colombia, Ecuador, Guyana, Peru and Venezuela. [1] [3] It is the only olingo species found east of the Andes. [2] The Latin species name honors Joel Asaph Allen, the American zoologist who first described the genus Bassaricyon. [4]

Description

The eastern lowland olingo is smaller than the northern olingo, but larger than the recently described olinguito ("little olingo"), the most montane member of the genus. [2] It is larger than the western lowland olingo subspecies B. medius medius from west of the Andes, but about the same size as the B. m. orinomus subspecies from eastern Panama. [2] The pelage is slightly darker than the western species. [2]

It has a head-body length of 30 to 45 centimetres (12 to 18 in), with a tail length of 40 to 53 centimetres (16 to 21 in). [2] It weighs 1.1 to 1.5 kilograms (2.4 to 3.3 lb). [2]

Taxonomy

The closest relative of the eastern lowland olingo is the western lowland species, B. medius, from which it diverged about 1.3 million years ago. [2]

Coatis, also known as coatimundis, are members of the family Procyonidae in the genera Nasua and Nasuella. They are diurnal mammals native to South America, Central America, Mexico, and the Southwestern United States. The name "coatimundi" comes from the Tupian languages of Brazil, where it means "lone coati". Locally in Belize, the coati is known as "quash".

<span class="mw-page-title-main">Procyonidae</span> Family of mammals

Procyonidae is a New World family of the order Carnivora. It includes the raccoons, ringtails, cacomistles, coatis, kinkajous, olingos, and olinguitos. Procyonids inhabit a wide range of environments and are generally omnivorous.

<i>Procyon</i> (genus) Genus of carnivores

Procyon is a genus of nocturnal mammals comprising three species commonly known as raccoons in the family Procyonidae. The most familiar species, the common raccoon, is often known simply as "the" raccoon, as the two other raccoon species in the genus are native only to the tropics and are less well known. Genetic studies have shown that the closest relatives of raccoons are the ring-tailed cats and cacomistles of genus Bassariscus, from which they diverged about 10 million years ago.

<span class="mw-page-title-main">Kinkajou</span> South American honeyeater (Potos flavus)

The kinkajou is a tropical rainforest mammal of the family Procyonidae related to olingos, coatis, raccoons, and the ringtail and cacomistle. It is the only member of the genus Potos and is also known as the "honey bear". Though kinkajous are arboreal, they are not closely related to any other tree-dwelling mammal group.

<span class="mw-page-title-main">Potto</span> Arboreal primate of west-central Africa

The pottos are three species of strepsirrhine primate in the genus Perodicticus of the family Lorisidae. In some English-speaking parts of Africa, they are called "softly-softlys".

<i>Bassariscus</i> Genus of carnivores

Bassariscus is a genus in the family Procyonidae. There are two extant species in the genus: the ringtail or ring-tailed cat and the cacomistle. Genetic studies have indicated that the closest relatives of Bassariscus are raccoons, from which they diverged about 10 million years ago in the Tortonian Age of the Miocene. The two lineages of Bassariscus are thought to have separated after only another two million years, making it the extant procyonid genus with the earliest diversification. Later diversification in the genus in the Pliocene and Pleistocene saw the emergence of two extinct species, Bassariscus casei and Bassariscus sonoitensis, respectively. Due to the more digitigrade stance of their legs compared to the plantigrade stance of other members of Procyonidae, some taxonomies place the genus as a separate family, Bassaricidae.. The name is a Greek word for fox ("bassaris") with a Latinized diminutive ending ("-iscus"). The genus was named by Elliott Coues in 1887, having previously been described by Lichtenstein in 1830 under the name Bassaris. Coues proposed the word "bassarisk" as the English term for animals in this genus. Its habitat includes semi-arid areas in the southwestern United States, the whole of Mexico, as well as moist tropical forests in Central America.

<i>Nasua</i> Genus of carnivores

Nasua is a genus of coatis of the family Procyonidae. Two additional species of coatis, commonly known as mountain coatis, are placed in the genus Nasuella.

<i>Nasuella</i> Genus of carnivores

Mountain coatis are two species of procyonid mammals from the genus Nasuella. Unlike the larger coatis from the genus Nasua, mountain coatis only weigh 1.0–1.5 kilograms (2.2–3.3 lb) and are endemic to the north Andean highlands in South America.

<i>Bassaricyon</i> Genus of carnivores

The genus Bassaricyon consists of small Neotropical procyonids, popularly known as olingos, cousins of the raccoon. They are native to the rainforests of Central and South America from Nicaragua to Peru. They are arboreal and nocturnal, and live at elevations from sea level to 2,750 m (9,020 ft). Olingos closely resemble another procyonid, the kinkajou, in morphology and habits, though they lack prehensile tails and extrudable tongues, have more extended muzzles, and possess anal scent glands. However, the two genera are not sisters. They also resemble galagos and certain lemurs.

<i>Nasuella olivacea</i> Species of carnivore

The western mountain coati or western dwarf coati is a small procyonid, found in cloud forest and páramo at altitudes of 1,300–4,250 metres (4,270–13,940 ft) in the Andes of Colombia and Ecuador. A population discovered in the Apurímac–Cuzco region of southern Peru has tentatively been identified as the western mountain coati, but may represent an undescribed taxon.

<span class="mw-page-title-main">Northern olingo</span> Species of carnivore

The northern olingo, also known as the bushy-tailed olingo or, simply, the olingo, is an arboreal (tree-dwelling) member of the raccoon family, Procyonidae, which also includes the coatimundis and kinkajou. Native to Central America, it was the first species of olingo to be scientifically described; while it is considered by some authors to be the only “true” olingo species, a review of the genus Bassaricyon had shown there to be a total of four species, two of those now being considered synonymous with the northern olingo. Its specific name honors William More Gabb (1839-1878), who found and collected the first specimen for western science.

The Cozumel coati, or Cozumel Island coati, is a coati from the Mexican island of Cozumel, in the Caribbean Sea. It is in the family Procyonidae, which also includes raccoons, olingos, and kinkajous.

<i>Nasuella meridensis</i> Species of carnivore

The eastern mountain coati or eastern dwarf coati is a small procyonid found in cloud forest and páramo at elevations of 2,000–4,000 m (6,600–13,100 ft) in the Andes of western Venezuela. Until 2009, it was included as a subspecies of the western mountain coati, but the eastern mountain coati is overall smaller, somewhat shorter-tailed on average, has markedly smaller teeth, a paler olive-brown pelage, and usually a dark mid-dorsal stripe on the back versus more rufescent or blackish, and usually without a dark mid-dorsal stripe in the western mountain coati. When the two were combined, they were classified as Data Deficient on the IUCN Red List but following the split the eastern mountain coati is considered endangered. A genetic analysis revealed that it should be regarded as a synonym of N. olivacea.
