Nasuella

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.[1][2]

Genetics and taxonomy

Genetic evidence indicates that the genus Nasua is only monophyletic if it also includes the mountain coatis. Based on cytochrome b sequences, Nasua nasua is the sister taxon to a clade consisting of Nasua narica plus both species of Nasuella.[3]

Until recently only a single species with three subspecies was recognized.[4] In 2009 this species was split into two species, the eastern mountain coati (N. meridensis) from Venezuela, and the western mountain coati (N. olivacea, with subspecies quitensis) from Colombia and Ecuador.[3]

Range and description

Externally, the two species of mountain coatis are quite similar, 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).[3] Both are found in cloud forest and páramo; at altitudes of 2,000–4,000 metres (6,600–13,100 ft) for the eastern mountain coati, and 1,300–4,250 metres (4,270–13,940 ft) for the western mountain coati.[3]

A population discovered in southern Peru (more than 1,000 km or 620 mi south of the previous distribution limit) has tentatively been identified as the western mountain coati, but may represent an undescribed taxon.[5]

Rare and little known

They are very poorly known, and the "combined species" (when only one species was recognized) has been classified as data deficient by the IUCN.[2] Their behavior largely appears to resemble that of the better-known Nasua coatis, although the mountain coatis feed less on fruit.[1][6]

Unlike the Nasua coatis, mountain coatis are very rare in captivity. Among ISIS registered institutions, only three zoos (all in the USA) reported that they had mountain coatis in early 2011,[7] but at least one of these appears to be a case of misidentification.[8] A mountain coati that was confiscated from poachers is kept at Bioparque la Reserva in Cota, Colombia.[8]

Bassaricyon

The genus Bassaricyon consists of small Neotropical procyonids, popularly known as olingos . 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. Olingos closely resemble the kinkajou in morphology and habits, though they lack prehensile tails and extrudable tongues, have more extended muzzles, and possess anal scent glands. They also resemble galagos and certain lemurs, which are primates.

Genetic studies have shown that the closest relatives of the olingos are actually the coatis; the divergence between the two groups is estimated to have occurred about 10.2 million years (Ma) ago during the Tortonian age, while kinkajous split off from the other extant procyonids about 22.6 Ma ago during the Aquitanian age. The similarities between kinkajous and olingos are thus an example of parallel evolution.

Bassariscus

Bassariscus is a genus in the family Procyonidae. There are two species in the genus: the ring-tailed cat or ringtail (B. astutus) and the cacomistle (B. sumichrasti). Genetic studies have indicated that the closest relatives of Bassariscus are raccoons, from which they diverged about 10 million years ago. 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.

The name is a Greek word for fox ("bassaris") with a Latinized diminutive ending ("-iscus"). The genus was first described by Elliott Coues in 1887. He 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.

Cacomistle

The cacomistle, Bassariscus sumichrasti, is a nocturnal, arboreal and omnivorous member of the carnivoran family Procyonidae. Its preferred habitats are wet, tropical, evergreen woodlands and mountain forests, though seasonally it will venture into drier deciduous forests.

Nowhere in its range (from southern Mexico to western Panama) is B. sumichrasti common. This is especially true in Costa Rica, where it inhabits only a very small area. It is completely dependent on forest habitat, making it particularly susceptible to deforestation.

The term cacomistle is from the Nahuatl language (tlahcomiztli) and means "half cat" or "half mountain lion"; it is sometimes also used to refer to the ringtail, Bassariscus astutus, a similar species that inhabits arid northern Mexico and the American Southwest.

Coati

Coatis, also known as the coatimundis (), are members of the raccoon family (Procyonidae) in the genera Nasua and Nasuella. They are diurnal mammals native to South America, Central America, and southwestern North America. The name coatimundi is purportedly derived from the Tupian languages of Brazil.The coati is also known in English as the hog-nosed coon.

Dwarf coati

Dwarf coati can refer to several species:

Cozumel Island coati (Nasua narica nelsoni) – from Cozumel Island, Mexico.

Eastern mountain coati (Nasuella meridensis) – from the Andes in Venezuela.

Western mountain coati (Nasuella olivacea) – from the Andes in Colombia and Ecuador.

Eastern lowland olingo

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. It is the only olingo species found east of the Andes. The Latin species name honors Joel Asaph Allen, the American zoologist who first described the genus Bassaricyon.

Guadeloupe raccoon

The Guadeloupe raccoon (Procyon lotor minor) is a common raccoon endemic on the two main islands Basse-Terre Island and Grande-Terre of Guadeloupe in the Lesser Antilles.

Kinkajou

The kinkajou ( KING-kə-joo) (Potos flavus) 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" (a name that it shares with the sun bear). Kinkajous are arboreal, a lifestyle they evolved independently; they are not closely related to any other tree-dwelling mammal group (e.g. primates, some mustelids, etc).

Native to Central America and South America, this mostly frugivorous mammal is not an endangered species, though it is seldom seen by people because of its strict nocturnal habits. However, they are hunted for the pet trade, for their fur (to make wallets and horse saddles) and for their meat. The species has been included in Appendix III of CITES by Honduras, which means that exports from Honduras require an export permit and exports from other countries require a certificate of origin or re-export. They may live up to 40 years in captivity.

Lutrogale

Lutrogale is a genus of otters, with only one extant species—the smooth-coated otter.

Nasua

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.

Nasuella meridensis

The eastern mountain coati or eastern dwarf coati (Nasuella meridensis) is a small procyonid found in cloud forest and páramo at altitudes of 2,000–4,000 metres (6,600–13,100 ft) in the Andes of western Venezuela. Until 2009, it was usually 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 rated as Data Deficient by the IUCN, but following the split the eastern mountain coati is considered endangered.

Nasuella olivacea

The western mountain coati or western dwarf coati (Nasuella olivacea) 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 (more than 1,000 km or 620 mi south of the previous distribution limit) has tentatively been identified as the western mountain coati, but may represent an undescribed taxon.Until 2009, the western mountain coati (then simply known as the mountain coati) usually included the eastern mountain coati as a subspecies, but that species 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 rated as Data Deficient by the IUCN, but following the split the western mountain coati is considered Near Threatened.There are two subspecies of the western mountain coati: N. o. olivacea and the slightly smaller and darker N. o. quitensis with less distinct rings on the tail. The former is known from Colombia and the latter from Ecuador, but the exact distribution limit between the two is not known.

Northern olingo

The northern olingo (Bassaricyon gabbii), also known as the bushy-tailed olingo or as simply the olingo (due to it being the most commonly seen of the species), is a tree-dwelling member of the family Procyonidae, which also includes raccoons. It was the first species of olingo to be described, and while it is considered by some authors to be the only genuine olingo species, a recent review of the Bassaricyon genus has shown that there are a total of four olingo species, although two of the former species should now be considered as a part of this species. Its scientific name honors William More Gabb, who collected the first specimen. It is native to Central America.

Olinguito

The olinguito , Bassaricyon neblina, is a mammal of the raccoon family Procyonidae that lives in montane forests in the Andes of western Colombia and Ecuador. The species was described as new in 2013. The species name neblina is Spanish for fog or mist, referring to the cloud forest habitat of the olinguito.On 22 May 2014 the International Institute for Species Exploration declared the olinguito as one of the "Top 10 New Species of 2014" among species discovered in 2013. It is the first new carnivoran mammal described in the Western Hemisphere in 35 years.

Procyon (genus)

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 (P. lotor), is often known simply as "the" raccoon, as the two other raccoon species in the genus are native only to the tropics and 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.

Procyonidae

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

South American coati

The South American coati or ring-tailed coati (Nasua nasua) is a species of coati and a member of the raccoon family (Procyonidae), from tropical and subtropical South America. In Brazilian Portuguese, it is known as quati. An adult generally weighs 2–7.2 kg (4.4–15.9 lb) and is 85–113 cm (33–44 in) long, with half of that being its tail. Its color is highly variable and the rings on the tail may be only somewhat visible, but its distinguishing characteristic is that it lacks the largely white snout (or "nose") of its northern relative, the white-nosed coati.

Western lowland olingo

The western lowland olingo (Bassaricyon medius) is a species of olingo from Central and South America, where it is known from Panama and from Colombia and Ecuador west of the Andes.

White-nosed coati

The white-nosed coati (Nasua narica), also known as the coatimundi (), is a species of coati and a member of the family Procyonidae (raccoons and their relatives). Local Spanish names for the species include pizote, antoon, and tejón, depending upon the region. It weighs about 4–6 kg (8.8–13.2 lb). However, males are much larger than females: small females can weigh as little as 2.5 kg (5.5 lb), while large males can weigh as much as 12.2 kg (27 lb). On average, the nose-to-tail length of the species is about 110 cm (3.6 ft) with about half of that being the tail length.
