Peromyscus ochraventer Baker 1951

Peromyscus ochraventer Baker 1951, Univ. Kansas Mus . Nat. Hist. Misc. Publ., 5: 213.

Type Locality: México, Tamaulipas, El Carrizo, 70 km (by highway) S Ciudad Victoria and 6 km W Panamerican Highway, 2800 ft (853 m).

Vernacular Names: El Carrizo Deermouse.

Distribution: Moist forests of S Tamaulipas and adjacent San Luis Potosí, México.

Conservation: IUCN – Lower Risk (lc).

Discussion: Species group indeterminate. Revised by Huckaby (1980) as part of the mexicanus species group ( sensu Hooper, 1968), an assignment not supported by allozymic analyses (Rogers and Engstrom, 1992). Departs from conservative karyotypic pattern exhibited by species of the mexicanus group (Robbins and Baker, 1981; Smith et al., 1986). Provisionally assigned to the furvus species group by Carleton (1989), but this association too is questioned by cytochrome b data, which indicate P. ochraventer to be strongly divergent genetically from both P. furvus and mexicanus group species ( P. mexicanus, P. melanocarpus) (Harris et al., 2000).
