SPECIES Peromyscus stephani

Author:Townsend, 1912.
Citation:Bull. Am. Mus. Nat. Hist., 31: 126.
Common Name:San Esteban Deermouse
Type Locality:México, Sonora, San Esteban Isl, 28°34'N, 113°21'W.
Distribution:Known only from Isla San Esteban.
Status:IUCN – Endangered.
Comments:P. boylii species group. Lawlor (1971a) demonstrated the boylii-like traits of P. stephani, which was previously classified in the subgenus Haplomylomys (Hooper, 1968), and favored its recognition as species. Electrophoretic investigations have sustained this affinity and status (Avise et al., 1974), but mitochondrial COIII gene sequences imply subspecific recognition within P. boylii (Hafner et al., 2001). In a denser taxonomic survey of boylii group forms, using the cytochrome b gene and including several subspecies of P. boylii sensu stricto, Tiemann-Boege et al. (2000) viewed P. stephani as sister taxon to the P. boylii-P. simulus clade and argued its status as species, an interpretation that best reflects the information sources so far consulted.
