Discussion: Phenacomyine (see remarks under Phenacomys ). Described as a subgenus of Phenacomys and conventionally recognized as such or as a complete synonym ( Carleton and Musser, 1984; Hall, 1981; Howell, 1926). Evidence for generic stature marshalled by Johnson (1968, 1973), but opinion on the validity of this rank has vacillated in recent systematic works (yes, as per George, 1999, Jones et al., 1997, and Musser and Carleton, 1993; no, as per McKenna and Bell, 1997, Repenning and Grady, 1988, and Verts and Carraway, 1998). Whether Arborimus is most closely related to Phenacomys or to some other arvicoline has not been cladistically substantiated with sampling that includes problematic species like albipes and other archaic arvicolines; the methodologies and critical information bases are here, but an informative sampling design must be assembled. Specific and subspecific classification basically set forth by Howell (1926) and Hall and Cockrum (1953), as part of Phenacomys , and by Johnson and George (1991).
