Oryzomys dimidiatus Thomas 1905

Oryzomys dimidiatus Thomas 1905 , Ann. Mag. Nat. Hist., ser. 7, 15: 586.

Type Locality: Nicaragua, Zelaya Dept., Río Escondido, 7 mi (11 km) below Rama.

Vernacular Names: Nicaraguan Oryzomys.

Distribution: SE Nicaragua.

Conservation: IUCN – Lower Risk (nt).

Discussion: Described as a species of Nectomys and included therein as incertae sedis by Hershkovitz (1944). Later designated as the type species of Micronectomys , subgenus Oryzomys , by Hershkovitz (1948b), who afterwards (1970) acknowledged the taxon as a nomen nudum (also see Pine and Wetzel, 1975:653). Morphological features resemble those of the O. couesi-palustris complex (Hershkovitz, 1970), a relationship supported by Sánchez et al. (2001). Only two specimens known (see Jones and Engstrom, 1986).
