Peromyscus eva Thomas 1898

Peromyscus eva Thomas 1898, Ann. Mag. Nat. Hist., ser. 7, 1: 44.

Type Locality: México, Baja California Sur, San José del Cabo.

Vernacular Names: Southern Baja Deermouse.

Synonyms: Peromyscus carmeni Townsend 1912 .

Distribution: Most of Baja California Sur and Carmen Isl, México.

Conservation: IUCN – Lower Risk (lc).

Discussion: P. eremicus species group. Ranked by Osgood (1909) as a race of P. eremicus, but Lawlor (1971 b), noting morphological differences and sympatry of the two, resurrected P. eva as a species, including the population on nearby Isla Carmen as a subspecies (also see Hafner et al., 2001). Specific differentiation sustained by electrophoretic and gene-sequence analyses (Avise et al., 1974; Riddle et al., 2000a, c); sister species to P. fraterculus (Riddle et al., 2000 c), another member of the Baja California Peninsular Desert fauna (e.g., Hafner and Riddle, 1997; Riddle et al., 2000 a, b). See Alvarez-Castañeda and Cortés-Calva (2003, Mammalian Species, 738).
