Perognathinae Coues 1875

Perognathinae Coues 1875, Proc. Acad. Nat. Sci. Philadelphia, 27: 277.

Synonyms: Perognathidinae Coues 1875 .

Genera: 2 genera with 26 species:

Genus Chaetodipus Merriam 1889 (17 species with 82 subspecies)

Genus Perognathus Wied-Neuwied 1839 (9 species with 63 subspecies)

Discussion: Subfamily name emended by Wood (1935); originally given by Coues as Perognathidinae. Wood (1935:89), Hafner (1978), and Hall (1981) included Microdipodops in the subfamily, a course not followed by Hafner and Hafner (1983), Wahlert (1985, 1988), Ryan (1989 a), and Williams et al. (1993). Williams et al. (1993:121) provide a key to the genera.
