This tree-dwelling mouse has a white belly and a very long tufted tail. It is nocturnal and is recorded in eastern African forests and thickets.
Its upper fur is dull olive-gray and its belly is sharply white. The tail is longer than the head and body, with a tuft at the tip.
It is nocturnal and arboreal. In Malawi, breeding is reported during the wet season (November–April), with litters of two to five.
