Oryzomys legatus Thomas, 1925 . Ann. Mag. Nat. Hist., ser. 9, 15:577.

TYPE LOCALITY: Bolivia, Tarija Dept., Carapari, 1000 m .

DISTRIBUTION: E Andean slopes of SC Bolivia and NW Argentina.

COMMENTS: Considered conspecific with O. capito by Hershkovitz (1960) and Cabrera (1961). Gardner and Patton (1976) viewed legatus as a probable synonym of O. nitidus, to which it appears closely related. Retained here as a species following the study of Massoia (1975; also Mares et al., 1989b) and pending determination of its status with regard to O. nitidus and O. intermedius (see comments therein).
