Peromyscus pectoralis Osgood 1904

Peromyscus pectoralis Osgood 1904, Proc. Biol. Soc. Wash., 17: 59.

Type Locality: México, Querétaro, Jalpan.

Vernacular Names: White-ankled Deermouse.

Synonyms: Peromyscus collinus Hooper 1952; Peromyscus eremicoides Osgood 1904; Peromyscus laceianus Bailey 1906 .

Distribution: SE New Mexico and C Texas, USA, south along the Mexican Plateau and Cordillera Oriental to N Jalisco and Hidalgo, México.

Conservation: IUCN – Lower Risk (lc).

Discussion: Species group indeterminate. Although traditionally arranged as a member of the boylii species group (Carleton, 1989; Hooper, 1968; Osgood, 1909), a robust variety of other systematic data leaves the matter of its affinity as unresolved (e.g., Rogers et al., 1984; Sullivan and Kilpatrick, 1991; Tiemann-Boege et al., 2000). Revised by Schmidly (1972), who recognized three subspecies that correspond to patterns of genetic differentiation (Kilpatrick and Zimmerman, 1976); consanguinity of included populations nevertheless suspect (see Avise et al., 1974). See Schmidly (1974, Mammalian Species, 49).
