Peromyscus madrensis Merriam 1898

Peromyscus madrensis Merriam 1898 , Proc. Biol. Soc. Wash., 12: 16.

Type Locality: México, Nayarit, Tres Marías Isls, María Madre Isl.

Vernacular Names: Tres Marias Deermouse.

Distribution: Tres Marías Isls, México.

Conservation: IUCN – Vulnerable.

Discussion: 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).
