This little-known species is endemic to northeastern Madagascar. The species has been recorded in the Masoala Peninsula, Zahamena National Park, and Betampona Strict Nature Reserve. There are only four confirmed recent localities, including two individuals with aberrant coloration in reed beds of Lac Alaotra at around 800 m (J. Durbin pers. comm.). There were also historical records from the area surrounding Lac Alaotra. The known records in rainforest range in elevation from 200 to 650 m. The type locality is unknown. There are historical records from Mananara MAB Reserve (Albignac 1973). Despite substantial trapping efforts in eastern rainforest over the last 15 years above 600 m, the species has not been recorded in any new sites (S.M. Goodman pers. comm.).
