Arborimus albipes (Merriam, 1901) . Proc. Biol. Soc. Washington, 14: 125.

TYPE LOCALITY: USA, California, Humboldt Co., Humboldt Bay, redwood forest near Arcata .

DISTRIBUTION: Pacific coastal zone south of Columbia River, from W Oregon to extreme NW California, USA.

COMMENTS: 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 .
