SPECIES Peromyscus madrensis

Author:Merriam, 1898.
Citation:Proc. Biol. Soc. Wash., 12: 16.
Common Name:Tres Marías Deermouse
Type Locality:México, Nayarit, Tres Marías Isls, María Madre Isl.
Distribution:Tres Marías Isls, México.
Status:IUCN – Vulnerable.
Comments:P. boylii species group. Treated as a subspecies of P. boylii by Osgood (1909) but considered distinct by Carleton (1977) in a revision of boylii group forms in W México. Viewed as closely related to P. simulus by Carleton et al. (1982), but cladistically basal to most other boylii group species in trees generated from cytochrome b data (Tiemann-Boege et al., 2000). Perhaps extirpated on María Magdalena Isl, where Rattus rattus is now abundant (Carleton et al., 1982; Wilson, 1991).
