Chaetodipus rudinoris (D. G. Elliot, 1903) |
Riddle et al. (2000) examined phylogenetic relationships within Chaetodipus baileyi and concluded that populations west of the Colorado River and Sea of Cortez should be recognized as a distinct species, Chaetodipus rudinoris.
Description
From Ceballos (ed., 2014): "Chaetodipus rudinoris is one of the largest species in the genus... The tail is longer than the length of head and body, and the tail is conspicuously crested. The ears are large. The pelage is smooth and it has bristles. Dorsal coloration varies from yellowish-gray to buffy ochre or pale buffy (Hall, 1981; Paulson, 1988)."

External measurements
Length measurements are in millimeters (mm) and weight measurements are in grams (g), unless stated otherwise. If available, the sample size (n=) is provided. If a range is not provided and n= is not given, then the listed measurement represents an average.

Similar species
From Ceballos (ed., 2014): "It can be distinguished from other species by its soft pelage that lacks bristles, large size, and dorsal coloration (Hall, 1981). Within the genus, C. rudinoris and C. baileyi are only surpassed in size by C. hispidus (Williams et al., 1993)."
