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 ).
