Wilson & Reeder, eds. (2005): Comments: Proposed as a subfamily by Patton and Reig (1989:76). This subfamily includes the Oligocene fossil forms, and the most primitive living genera of South American echimyids. Included in the Heteropsomyinae by McKenna and Bell (1997). Molecular data (Leite and Patton, 2002) suggest that the genera Clyomys and Euryzygomatomys are allied with the myocastorids and capromyids and that this subfamily is not a monophyletic unit
