Biol. Soc. Wash., 14: 125 . Type Locality: USA , California , Humboldt Co., Humboldt Bay, redwood forest near Arcata. Vernacular Names: White-footed Vole . Distribution: Pacific coastal zone south of Columbia River, from W Oregon to extreme NW California , USA . Conservation: IUCN – Data Deficient. Discussion: More generalized terrestrial form and habits have suggested a closer relationship to Phenacomys intermedius (e.g., Hall, 1981 , placed albipes and intermedius together in subgenus Phenacomys ). Johnson and Maser (1982) enumerated character states that instead support closer congruence of albipes with species of Arborimus . However, see Repenning and Grady (1988) , who diagnosed the subgenus Paraphenacomys of Phenacomys to contain albipes , which they viewed as more distantly related to the sister species intermedius and longicaudus ; Paraphenacomys is known by fossil forms from the late Pliocene of North America and Beringian Asia ( Repenning and Grady, 1988 ; Repenning et al., 1987). See Verts and Carraway (1995 , Mammalian Species, 494).
