Microtus umbrosus

Zempoaltépec Vole

Order: Rodentia
Family: Cricetidae


Conservation Status: Endangered.

The largest Mexican vole, the Zempoaltepec Vole, has very large hind feet; only the Tarabundi Vole's feet rival it. Zempoaltepec Voles are found in humid, dense forests, where they live in burrows and dig long tunnels in well-drained soil. Their range is very restricted; they have been found only in a small, semi-isolated mountain range. They are not closely related to any other Microtus, and no fossils of this species have been found.

Range: Total Length: 164-188 mm; Tail: 49-65 mm
