Oryzomys intermedius (Leche, 1886) . Zool. Jahrb., 1:693.

TYPE LOCALITY: Brazil, Rio Grande do Sul, Taquara do Mundo Novo .

DISTRIBUTION: SE Brazil (Bahia to Rio Grande do Sul), E Paraguay, and NE Argentina (fide Massoia, 1975).

COMMENTS: Classified as a subspecies of O. capito by Cabrera (1961) although its distinction from laticeps (= O. capito) was earlier maintained by Moojen (1952). Gardner and Patton (1976) perceived the closer kinship of intermedius to O. nitidus and suggested their synonymy. Oryzomys intermedius, O. legatus, O. macconnelli, and O. nitidus form a closely-related complex whose interrelationships, specific stature, and distributions deserve investigation.
