Taxonomy

The genus Pudu was first erected by English naturalist John Edward Gray in 1850. Pudua was a Latinized version of the name proposed by Alfred Henry Garrod in 1877, but was ruled invalid. Pudus are classified in the New World deer subfamily Capreolinae within the deer family Cervidae. The term "pudú" itself is derived from the language of the Mapuche people of the Los Lagos Region of south-central Chile.
