Abrocomidae Miller and Gidley 1918

Abrocomidae Miller and Gidley 1918, J. Wash. Acad. Sci., 8 (13): 447.

Genera: 2 genera with 10 species:

Genus Abrocoma Waterhouse 1837 (8 species with 2 subspecies)

Genus Cuscomys Emmons 1999 (2 species)

Discussion: The phylogenetic affinity of Abrocoma has been problematic; Ellerman (1940) placed within the family Echimyidae, Landry (1957) within the family Octodontidae whereas Patterson and Wood (1982) assigned familial status. Glanz and Anderson (1990) suggested a sister relationship between Abrocomidae and Chinchillidae . Molecular data (Gallardo and Kirsch, 2001; Honeycutt et al., 2003; Huchon and Douzery, 2001) and allozyme data (Köhler et al., 2000) support familial status within the superfamily Octodontoidea and most suggest a basal position for the Abrocomidae .
