About Oryzomys dimidiatus in brief
Oryzomys dimidiatus is a medium-sized rice rat. It is known from only three specimens, all collected in southeastern Nicaragua since 1904. The upperparts are gray-brown and the underparts aregrayish, not buffy as in O. couesi. The species may be semiaquatic, spending some time in the water. Its conservation status is currently assessed as “Least Concern”. It is now recognized as one of eight species in the genus OryZomys. It occurs with other species of mainly small-sized rodents, along with hundreds of other species, in the Central American region. It has been placed in the family Cricetidae along with the marsh rice rat and other small rodents of the family Oryzomyini in the subgenus Sigmodina.
It was placed in Nectomys upon its discovery, but was later classified in its ownsubgenus of Ory Zomys and recognized as closely related to other species now placed in Ory zomys, including the marsh Rice rat and Ory couesi, which occurs in the same region. The first known specimen was obtained by W. G. Palmer in 1904 and the next year, Oldfield Thomas of the British Museum of Natural History described this animal as the holotype of a new species he named NECTomysDimidiatus. In 2006, Marcelo Weksler and coworkers removed most of the species formerly place in Ories from the genus, because they are not related to the type species.
