Micromys

Micromys is a genus of small rodents in the subfamily Murinae. The genus contains two living species: the widespread Eurasian harvest mouse (Micromys minutus) of much of Europe and Asia; and the more restricted Indochinese harvest mouse (Micromys erythrotis) of Vietnam, southern China, and perhaps nearby regions. Fossils of Micromys date back to the Late Miocene and include at least 10 extinct species, which form several lineages.

== Taxonomy == Micromys is not closely related to any other murine genus, which has made elucidating its phylogenetic relationships difficult. Previously, it was placed in a distinct murine clade also containing Hapalomys, Chiropodomys, and Vandeleuria, but studies have since found this clade to be polyphyletic, and instead found Micromys to belong to a division of its own that forms a sister group to the tribe Rattini, which contains the true rats among many other genera. It has been debated over whether Micromys belongs in its own tribe (Micromyini) or is a basal member of the Rattini, but the American Society of Mammalogists presently classifies it in Rattini.
