Oligoryzomys longicaudatus (Bennett, 1832) . Proc. Zool. Soc. Lond., 1832:2.

TYPE LOCALITY: Chile, Valparaiso Prov. (as suggested by Osgood, 1943:143) .

DISTRIBUTION: NC to S Andes, approximately to 50°S latitude, of Chile and Argentina.

SYNONYMS: agilis , amblyrrhynchus, araucanus, commutatus, coppingeri, diminutivus, dumetorum, exiguus , glaphyrus, macrocercus , melaenus, melanizon, mizurus, nigribarbis, pernix, peteroanus, philippii, saltator .

COMMENTS: Formerly encompassed most Andean populations of Oligoryzomys (see Cabrera, 1961). Morphometric variation among Chilean populations investigated by Gallardo and Palma (1990), who placed philippii in full synonymy with O. longicaudatus and removed magellanicus to specific status. Relationships and level of divergence from allopatric forms like O. destructor and O. nigripes warrant study (see Carleton and Musser, 1989). Attribution of numerous Philippi (1900) epithets follows Osgood (1943).
