ORDER LAGOMORPHA Brandt, 1855

Mammalogists previously united Lagomorpha with Rodentia as a single order (Carleton & Musser 2005). These two orders were frequently considered as a single cohort ( Glires; Landry 1999) that diverged into two orders at the Cretaceous-Paleogene boundary (Huchon et al. 2002).

The order Lagomorpha in Korea contains two families, two genera and three species. Lagomorphs in the Family Ochotonidae only inhabit extreme northern Korea (southern limit is Mt. Myohyang), whereas, members of the Leporidae commonly occur throughout the Korean Peninsula.
