This rodent is known from Ankarana Special Reserve in northern Madagascar. Study specimens came from forest with limestone pinnacles and were trapped on the ground and in vines and trees. Whether specimens from nearby reserves belong to the same species remains unresolved.
The soft, fine dorsal fur is dark brown at the base and medium buff at the tips. The back has a dark agouti appearance, with a darker midline band; the underside varies from nearly white to gray.
All study specimens came from forest on the Ankarana Massif. The species was found in both dry deciduous and disturbed forest, often around limestone pinnacles; traps caught it on the ground, in vines, and on fallen trees. The authors describe it as a forest-dweller that mainly uses climbing surfaces.
An extinction-risk assessment has not been added yet.
