Viscacha
Viscachas or vizcachas are rodents of two genera (Lagidium and Lagostomus) in the family Chinchillidae. They are closely related to chinchillas, and look similar to rabbits. There are five extant species of viscacha:
Extant species
- Plains viscacha (Lagostomus maximus): Resident of the Pampas of Argentina, easily differentiated from other viscachas by black and gray mustache-like facial markings. This species lives colonially in warrens of ten to over one hundred. It is very vocal and emits alarm calls. The plains viscacha can strip grassland used to graze livestock; this caused ranchers to consider the rodent a pest species.
- Lagidium ahuacaense: a newly described species of mountain viscacha from the Ecuadorean Andes.[1]
- Northern viscacha (Lagidium peruanum): Native to the Peruvian Andes at those elevations between the tree line and the snow line. It is dorsally gray or brown in color, with a bushy tail and long, furry ears. This species lives in large colonies separated into individual family units, like an apartment complex. It eats a wide range of plant matter, settling for almost anything it can find growing in the harsh, rocky environment.
- Mountain viscacha (Lagidium viscacia): Also called southern viscacha, this species is similar to the northern viscacha, but its pelage is more red in color. It lives in similar habitat in the Andes.
- Wolffsohn's viscacha (Lagidium wolffsohni): Little is known about this species, as it is rarer than the other four viscachas.

Chinchillidae
The family Chinchillidae contains the chinchillas, viscachas, and their fossil relatives. They are restricted to southern and western South America, often in association with the Andes. They are large rodents, weighing from 800 g (28 oz) to 8 kg (18 lb), with strong hind legs and large ears. All species have thick, soft fur, which is considered valuable in some species.[2]
Classification
There are three extant and three fossil genera currently recognized.
- †Eoviscaccia incertae sedis
- Subfamily Chinchillinae
- Chinchilla - chinchillas
- Lagidium - mountain viscachas
- Subfamily Lagostominae
- Lagostomus - plains viscachas
- †Pliolagostomus
- †Prolagostomus
