M. nana, M. bricenii, M. chunyi,  and M. rufina are found in forest and high-altitude grassland (M. nana in Atlantic forest; the remaining species in Andean cloud forest, elfin forest and páramo). They are medium to small in size, and the pelage is reddish. In most, a part of the legs and the upper part of the head are blackish or dark gray, but in M. chunyi, the foreparts and neck are also blackish or dark gray.
