Abstract
The Archaeolaginae of North America, excluding Archaeolagus and Panolax, include the following genera and species: Hypolagus vetus, H. parviplicatus, H. gidleyi n. sp., H. fontinalis, H. tedfordi n. sp., H. furlongi, H. edensis, H. oregonensis, H. ringoldensis, H. regalis, H. voorhiesi n. sp., H. arizonensis, Lepoides lepoides n. gen. and sp., Pewelagus dawsonae, and ?Pewelagus mexicanus. ?Hypolagus apachensis is referred to the Leporinae. The genus Notolagus is referred to the Leporinae and Paranotolagus is tentatively referred to the Leporinae. Lepoides lepoides n. gen. and sp. is tentatively thought to be a jack rabbit ecomorph, while some species of Hypolagus possibly cottontail ecomorphs. The Archaeolaginae of North America became extinct by the end of the Blancan land mammal age (Pliocene).
