The olinguito (/ˌoʊlɪŋˈɡiːtoʊ/ oh-lihn-GEE-toe;[1] Bassaricyon neblina), which is Spanish for "little olingo", is a mammal of the genus Bassaricyon in the family Procyonidae (the raccoon family) that lives in montane forests in the Andes of western Colombia and Ecuador.
Description
The olinguito is distinct from the other species within the genus, popularly known as "olingos", and also from the kinkajou (kinkajous resemble olingos, but are not closely related).[2][3] Its average weight is 900 grams (2 lb), making it the smallest procyonid.[1][4][5] The animal is an omnivorous frugivore[6] that eats mainly fruits (such as figs), but also insects and nectar resulting in feces the size of small blueberries.[5][7] The olinguito is thought to be solitary, nocturnal[6]: 29:30 and moderately reclusive. Olinguitos appear to be strictly arboreal.[3][6] They have a single pair of mammae, and probably produce a single offspring at a time.[3][5][6]
Distribution and habitat
Specimens of the species have been identified from the Andean cloud forest stretching from western Colombia to Ecuador.[5][8][9] Its discovery was announced on 15 August 2013[4][6] and confirmed in the wild.[3][4] The species is not considered to be immediately at risk,[4] but it is estimated that over 40 percent of the animal's potential range has been deforested.[4][7]
Discovery
Its discovery was announced on 15 August 2013 by Kristofer Helgen, the curator of mammals at the Smithsonian National Museum of Natural History, olingo expert Roland Kays of the North Carolina Museum of Natural Sciences and collaborators.[4][6][10][11][12] Helgen discovered specimens of the species in storage at Field Museum of Chicago and used DNA testing to confirm a new species.[5]
The researchers who identified the species were unable to discover any local names specific to it.[6]
The discovery was the first identification of a new mammal species of the order Carnivora[note 1][6] in the Americas in 35 years.[4][6] Olinguitos were regularly seen and even publicly exhibited decades before they were recognized as members of a new species. The animal had previously been confused with its taxonomic cousins, the olingos. One such example was Ringerl, an olinguito who lived in the National Zoo in Washington, D.C., for a year and also toured many other zoos.[6][13] Researchers unsuccessfully tried to breed her with olingos, not realizing she was a different species.[6] Ringerl died in 1976.[1]
Taxonomic evaluation
The olinguito is smaller than the other species in the genus Bassaricyon.[4] It is also much furrier, has a different tooth configuration, a shorter tail, and smaller ears.[13] The olinguito is found in the northern Andes at altitudes between 1500 to 2750 meters[3] above sea level, which is much higher than the habitats for other olingos.[7]
Based on morphological distinctions, four olinguito subspecies have been described: the nominate Bassaricyon neblina neblina, and B. n. osborni, B. n. hershkovitzi, and B. n. ruber.[3]
Comparison of DNA from two olinguito subspecies to other olingo and related species was carried out on the basis of genetic dissimilarity derived from Kimura modeling of differences in base-pair composition of mitochondrial cytochrome b. The genetic divergence between olinguitos and other olingos makes olinguitos a sister lineage to the rest of the genus, and is equivalent to differences between species which have been assigned to separate subgenera or genera.[3] This split apparently occurred about 3.5 million years ago, suggesting that the earliest diversification of the genus took place in northwestern South America shortly after the ancestors of olingos first invaded the continent from Central America as part of the Great American Interchange.[3]
Notes
- ^ The olinguito is omnivorous: not all carnivoran species are carnivores. (Further explanation may be found in the linked articles, including carnivoran diet specializations.)
