Subfamily Rhizomyinae Winge, 1887 . E Museo Lundii, 1:109.

SYNONYMS: Tachyoryctinae.

COMMENTS: Diagnosed and reviewed by Carleton and Musser (1984) and Flynn (1990), who also summarized relationships of extant and extinct genera in form of a cladogram. Flynn treated the group as a separate family and utilized Tachyoryctinae for Tachyoryctes and Rhizomyinae for Rhizomys and Cannomys; in our scheme these two groups would be treated as tribes.
