The Colombian forest mouse (Chilomys instans) is a species of rodent in the family Cricetidae. Some authorities consider it to be the only species in the genus Chilomys, while others accept Chilomys fumeus as being a valid species. Chilomys instans is found in Colombia, Ecuador, and Venezuela.
Description
Chilomys instans is very similar to Chilomys fumeus in size and appearance. Both are small sigmodontines, with a head-and-body length of 72 to 102 mm (2.8 to 4.0 in) and a tail length of 102 to 137 mm (4.0 to 5.4 in). The ears are medium-sized and clad in short hairs, and the body fur is woolly and short. The dorsal surface is dark grey to greyish-brown and the underparts are a similar colour. The hind feet are narrow and the slender tail is clad with short hairs, and often has a white tip. There are three pairs of mammary glands. The chief differences between the two species lies in the morphology of the skull.[2]
Status
The International Union for Conservation of Nature has rated this species as being of "least concern" on the basis that it has a wide distribution, is presumed to have a large population, occurs in several protected areas, and is not likely to be declining at a sufficient rate to qualify to be listed in a more-threatened category.[1]
