Reithrodontomys microdon(Rodentia: Cricetidae)

Abstract

AbstractReithrodontomys microdon Merriam, 1901 is a cricetid rodent commonly called the small-toothed harvest mouse. It is a small-bodied mouse with deep reddish-fulvous fur, a tail longer than the head–body length, and long, dark, and nearly naked ears. There are distinctive dark rings around the eyes. As 1 of 24 species of the genus Reithrodontomys and among the most arboreal, its populations inhabit cool moist forests of high mountains in isolated pockets across its geographic distribution in central Mexico, Oaxaca (Mexico), Chiapas (Mexico,) and west-central Guatemala. Reithrodontomys microdon is considered “Least Concern” (LC) by the International Union for Conservation of Nature (IUCN), mainly due to habitat loss caused by annual and perennial nontimber crops, as well as logging and wood harvesting.
