Silky pocket mouse Perognathus flavus, copyright Bob Beatson.

Belongs within: Heteromyidae.

The Perognathinae, pocket mice, are two genera Perognathus and Chaetodipus (sometimes united in a single genus) of small mouse-like heteromyid rodents found in arid regions of western North America. Their relationship is supported by biochemical data (Hafner & Hafner 1983).
