This species has a very restricted range in north-eastern Madagascar that includes the humid forest belt extending from Maroantsetra to the Andapa Basin and the Marojejy Massif, but the precise limits of its distribution are unknown. Marojejy National Park represents the northern limit of its known distribution and the forests of Makira and the Antainambalana River are currently regarded as the southern limit. They are patchily distributed and occur at low densities. It is most commonly encountered at elevations between 700 and 1,875 m asl (Patel et al. 2007; Mittermeier et al. 2008).
