Peromyscus yucatanicus J. A. Allen and Chapman 1897

Peromyscus yucatanicus J. A. Allen and Chapman 1897 , Bull. Am. Mus . Nat. Hist., 9: 8.

Type Locality: México, Yucatán, Chichén Itzá.

Vernacular Names: Yucatan Deermouse.

Synonyms: Peromyscus badius Osgood 1904 .

Distribution: N Yucatán Peninsula, México.

Conservation: IUCN – Lower Risk (lc).

Discussion: P. mexicanus species group. The notion that P. yucatanicus is most closely related to P. mexicanus (e.g., Hooper, 1968; Lawlor, 1965) has not found support from morphological information ( Carleton, 1973; Huckaby, 1980); the weak differentiation in chromosomes and allozymes offers little resolution of their level of kinship, as is true among mexicanus group species in general ( Rogers and Engstrom, 1992; Rogers et al., 1984; Smith et al., 1986). Huckaby (1980) followed Lawlor (1965) in treating P. yucatanicus as monotypic; Hall (1981) accepted Osgood’s (1909) subspecific arrangement. See Young and Jones (1983, Mammalian Species, 196).
