Incan Caenolestid	Lestoros inca	southern Andes; moist habitats, in elfin and secondary forests, and Baccharis scrubs	appears to be nocturnal and terrestrial		least concern	this caenolestid has a relatively stronger cranium and shorter mandible, suggesting that it can feed on tougher material than can other shrew opossums
Long-nosed Caenolestid	Rhyncholestes raphanurus	occurs in temperate forests; prefers cool, moist areas; appears to live in burrows and fallen logs	appears to be nocturnal and terrestrial	lactating females have been reported in May as well as from Oct to March	near threatened	long, pointed snout, small eyes and ears, and one claw on a digit of each of the thin limbs; lacks a marsupium and has 7 nipples, unlike the 4 typical of other caenolestids; the tail helps in balancing the body during locomotion; its relatively shorter tail could imply lesser agility in comparison to other caenolestids, and moreover, the tail can be used to store fat, and is reportedly thickest during early winter

	Monito del Monte (Colocolo Opossum)	Dromiciops gliroides		Valdivian temperate rainforests of the southern Andes, living in thickets of mountain bamboo; dense, humid forests of highland Argentina and Chile, mainly living in trees, where it constructs spherical nests of water resistant colihue leaves	nocturnal; arboreal; torpor and uses mossy nests for protection from bad weather; hibernation; sole dispersal agent for the loranthacous mistletoe	well-formed, fur-lined marsupium containing 4 mammae; normally reproduce in the spring once a year; litter varies from 1-5, only 4 of which can be fed and survive; when young are mature enough to leave the pouch, approx. 5 months, they are nursed in a distinctive nest, then carried on the mother's back, and remain in association with her after weaning; both sexes reach sexual maturity after 2 years	near threatened	only extant species in the ancient order Microbiotheria

Order Diprotodontia

Suborder Vombatiformes

Common Name	Name	Map	Habitat	Behavior	Reproduction	Status	Traits
Northern Hairy-nosed Wombat	Lasiorhinus krefftii			nocturnal; digs networks of burrows, and known to share them with up to 10 individuals, equally divided by sex	slightly larger than the common wombat and able to breed somewhat faster, giving birth to 2 young every 3 years on average; young are usually born during the wet season, between Nov and April; young stay in pouch for 8-9 months, weaned at 12 months	critically endangered	one of the rarest land mammals; nose crucial to its survival because it has very poor eyesight, so it must detect its food in the dark through smell; the fat reserves and low metabolic rate of this species permit it to go without food for several days when food is scarce

Common Wombat	Vombatus ursinus		variety of habitats, rainforest, eucalyptus forest, woodland, alpine grassland, and coastal areas; adapted to farmland in some regions; higher mountainous areas northern of its distribution; each individual has an established range	often nocturnal; solitary and territorial; digs a tunnel system, with one entrance, and sometimes one exit also, and many can live in the same burrow	can breed every 2 years and produce a single offspring; gestation is about 20-30 days; young remain in pouch for 5 months, are weaned at around 12-15 months, and are usually independent by 18 months	least concern	distinguished from both hairy-nosed wombats by its bald nose
