Scelidotheriinae is a subfamily of extinct ground sloths within the order Pilosa, suborder Folivora and family Mylodontidae, related to the other extinct mylodontid subfamilies, Lestodontinae and Mylodontinae. The only extant families of the suborder Folivora are Bradypodidae and Megalonychidae. Erected as the family Scelidotheriidae by Ameghino in 1889, the taxon was demoted to a subfamily by Gaudin in 1995.[1][2]

Together with the rest of Mylodontidae and the engimatic Pseudoprepotherium, the scelidotheriines form the superfamily Mylodontoidea. Chubutherium is an ancestral and very plesiomorphic member of this subfamily and does not belong to the main group of closely related genera.
