==Characteristics== Microryzomys species are small members of the rodent tribe Oryzomyini, weighing in the region of , and characterised by their long soft fur and tail longer than their head-and-body-length. They have small hind feet with six fleshy pads on the under surface, and with the fifth toe nearly as long as the middle three. The four pairs of mammae are arranged in the typical fashion for members of the tribe. At one time, this genus was considered to be a subgenus of Oryzomys, but Carleton and Musser (1989) raised it to full generic status on the basis of various anatomic details of skull and dentition and on certain morphological traits.
