Tapirus

Tapirus is a genus of tapir which contains the living tapir species. The Malayan tapir is usually included in Tapirus as well, although some authorities have moved it into its own genus, Acrocodia.^[2]

	South American tapir (also called the Brazilian tapir or lowland tapir)	Tapirus terrestris (Linnaeus, 1758)	Venezuela, Colombia, and the Guianas in the north to Brazil, Argentina, and Paraguay in the south, to Bolivia, Peru, and Ecuador in the West
	Mountain tapir (also called the woolly tapir)	Tapirus pinchaque (Roulin, 1829)	Eastern and Central Cordilleras mountains in Colombia, Ecuador, and the far north of Peru.

The Kabomani tapir was at one point recognized as another living member of the genus, but is now considered to be nested within T. terrestris.^[4][5]

Evolution

Tapirus first appeared in the Late Miocene in North America, with Tapirus webbi perhaps the oldest known fossil species.

Tapirus spread into South America and Eurasia during the Pliocene. It has been suggested that the tapirs that inhabited North America during the Late Pleistocene may be derived from a South American species that remigrated north, perhaps Tapirus cristatellus.^[6]

Tapirs suffered large-scale extinctions at the end of the Pleistocene, and went completely extinct north of southern Mexico.
