Distribution: E Oregon and SW Idaho , south through Nevada and parts of Utah and W Colorado , USA , to EC Baja California Norte and NW Sonora , México . Conservation: IUCN – Lower Risk (lc). Discussion: P. crinitus species group. Revised by Osgood (1909) ; subspecific taxonomy updated by Hall and Hoffmeister (1942) . Initially placed in subgenus Haplomylomys ( Osgood, 1909 ) ; later transferred to subgenus Peromyscus ( Hooper and Musser, 1964 b ) . Karyotype viewed as primitive for the genus ( Greenbaum and Baker, 1978 ; Stangl and Baker, 1984 b ). Population on Isla San Luís Gonzaga ( pallidissimus ), N Sea of Cortez, genetically similar to mainland P. crinitus and retained as subspecies ( Hafner et al., 2001 ). A composite of at least two species, the status of long-tailed forms (e.g., disparilis and delgadilli ) in particular meriting reassessment. See Johnson and Armstrong (1987 , Mammalian Species, 287).
