What is "monticolomys"

Monticolomys is a genus of rodents within the subfamily Nesomyinae of the family Nesomyidae, and is closely related to Macrotarsomys. The only species, Monticolomys koopmani, also known as the Malagasy mountain mouse or Koopman's montane voalavo, is found in the highlands of eastern Madagascar. A small mouse-like rodent, M. koopmani is dark brown on the upperparts and dark gray below. It has small, rounded, densely haired ears and broad feet with well-developed pads. The long tail lacks a tuft at the tip. The skull is delicate and lacks crests and ridges on its roof.

First collected in 1929, Monticolomys koopmani was not formally described until 1996, but it is now known to have a broad distribution. Active during the night, it occurs in both montane forest and human-disturbed grasslands and feeds on fruits and seeds. A scansorial animal, it climbs trees but also lives on the ground. Although habitat destruction may pose a threat, it is classified as " Least Concern" on the IUCN Red List.
