They found that the mole-ratsubfamilies (Spalacinae and Rhizomyinae) were the sister group to all other muroids, but they were unable to resolve the branching pattern, among most of the remaining subfamilies and speculated that robust resolution may never be achieved.
The only missing subfamilies are the rare or depauperate Lophiomyinae (maned rat), Platacanthomyinae (Malabar spiny mouse and blind tree mouse), Myospalacinae (fossorial zokors), and Mystromyinae (mouse-like hamster).
The revised definition of the Muridae is the most recent common ancestor of the Murinae, Deomyinae, and Gerbillinae and all of its descendants.
