Subfamily Euchoreutinae Lyon, 1901 . Proc. U. S. Natl. Mus., 23 (1228):666.

COMMENTS: Based on crown structure of the molars, and characters of the mastoid region, Shenbrot (1992) proposed that Euchoreutinae is most closely related to Sicistinae . The results of Stein's (1990) study of limb musculature placed Euchoreutinae as a sister group of Zapodinae and Allactaginae . See comment under Dipodidae .
