The subfamily Deomyinae consists of four genera of mouse-like rodents. These were placed in the subfamilies Murinae and Dendromurinae until very recently. They are sometimes called Acomyinae, particularly in references that predate the discovery that the link rat, Deomys ferugineus, is part of the clade. Deomyinae is the older and more appropriate name.
Deomyines share no morphological characteristics that can be used to separate them from other muroids. Subtle aspects of the third upper molar have been suggested, though. This subfamily is united solely on the basis of shared genetic mutations. These conclusions have demonstrated good statistical support using nuclear and mitochondrial DNA, as well as DNA-DNA hybridization.
