Biol. Soc. Wash., 17: 61 . Type Locality: México , Chihuahua , Colonia García. Vernacular Names: Chihuahuan Deermouse . Distribution: WC Chihuahua , México . Conservation: IUCN – Vulnerable. Discussion: Species group indeterminate. A distinctive species of enigmatic relationships: initially placed with the truei group ( Osgood, 1909 ) but provisionally reassigned to the boylii group by Hoffmeister (1951 ; also see Bradley and Schmidly, 1987 , and commentary by Anderson, 1972:348 ). Allozymic distance data weakly support the latter association (Bradley et al., 1996; Kilpatrick and Zimmerman, 1975 ; Schmidly et al., 1985 ), but mitochondrial DNA (cytochrome b ) interpretations of its kinship are inconclusive ( Tiemann-Boege et al., 2000 ).
