Nasuella olivacea
Template:Short description Template:Speciesbox
The western mountain coati or western dwarf coati (Nasuella olivacea) is a small procyonid, found in cloud forest and páramo at altitudes of Script error: No such module "convert". in the Andes of Colombia and Ecuador.[1] A population discovered in the Apurímac–Cuzco region of southern Peru (more than Script error: No such module "convert". south of the previous distribution limit) has tentatively been identified as the western mountain coati, but may represent an undescribed taxon.[2]
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).[1] 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.[3] After a genetic analysis in 2020, the American Society of Mammalogists currently considers N. meridensis a synonym of N. olivacea.[4]
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.[1] The former is known from Colombia and the latter from Ecuador, but the exact distribution limit between the two is not known.[1]
