In 2014, which of these mammal species was the last to be officially identified?

The olinguito is a mammal of the raccoon family that lives in high altitude forests in the Andes of western Colombia and Ecuador. The species name 'neblina' is Spanish for fog or mist, referring to the cloud forest habitat of the 'olinguito'. Its discovery was announced by the curator of mammals at the Smithsonian National Museum of Natural History in 2013.

In 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. DNA tests confirmed this new species although it was already displayed in museums and zoos, but misidentified prior to 2013. The animal had previously been confused with its taxonomic cousins, the olingos.

Its average weight is 900 grams (2 lb). Its body is approximately 355 mm (14.0 in) long, and its tail 335–424 mm (13.2–16.7 in) long. It is also much furrier and has a shorter tail and smaller ears than others that share its genus. The animal eats mainly fruits, insects and nectar. The olinguito is solitary, nocturnal and moderately reclusive. Olinguitos live primarily in trees and mostly produce a single offspring at a time.

The species is not considered to be immediately at risk, but it is estimated that over 40 percent of the animal's potential range has been deforested. As of now, no strict efforts are known to be in place in order to reduce habitat destruction.
