'''Viscacha''' or '''vizcacha''' ({{IPAc-en|UK|v|ɪ|ˈ|s|k|æ|tʃ|ə}}, {{IPAc-en|US|v|ɪ|ˈ|s|k|ɑː|tʃ|ə}}) are rodents of two genera (''[[Lagidium]]'' and ''[[Lagostomus]]'') in the family [[Chinchillidae]]. They are native to South America and [[convergent evolution|convergently]] resemble [[rabbits]].<ref>{{cite web|last1=Nosowitz|first1=Dan|title=Mystery Animal Contest: Who Is This Fuzzy Sniffler?|url=https://www.popsci.com/science/article/2013-04/mystery-animal-contest-who-fuzzy-sniffler|website=Popsci|date=18 April 2013 |publisher=Popular Science|access-date=15 April 2018|language=en}}</ref>
The five [[Extant taxon|extant]] species of viscacha are: *The [[Plains viscacha]] (''Lagostomus maximus''), a resident of the [[Pampa]]s of [[Argentina]], is easily differentiated from other viscachas by black and gray mustache-like facial markings. This species lives colonially in [[Warren (burrow)|warren]]s of 10 to over 100. It is very vocal and emits alarm calls. The plains viscacha can strip grassland used to graze livestock; this has caused ranchers to consider the rodent a pest species. *''[[Lagidium ahuacaense]]'' is a newly described species of mountain viscacha from the Ecuadorian Andes.<ref>{{cite journal |last1=Ledesma |first1=K.
