Arborimus longicaudus (True 1890)

[Phenacomys] longicaudus True 1890, Proc. U. S. Natl. Mus ., 13: 303.

Type Locality: USA, Oregon, Coos Co., Marshfield.

Vernacular Names: Red Tree Vole.

Synonyms: Arborimus silvicola (A. B. Howell 1921) .

Distribution: Coastal area and Western Cascade Mtns, W Oregon (Verts and Carraway, 1998:Fig. 11-106), USA.

Conservation: IUCN – Lower Risk (lc).

Discussion: Although Howell (1926) recognized silvicola as a nominal species, subsequent research has favored its synonymy under A. longicaudus (Johnson, 1968), where it has been maintained as a subspecies (Hall, 1981; Johnson and George, 1991). Formerly included populations in California assigned to the new species A. pomo (see next account). See Hayes (1996, Mammalian Species, 532).
