This species is listed as data deficient in view of continuing uncertainties as to its extent of occurrence, status and ecological requirements. Its forest habitat is receding due to subsistence agriculture, timber extraction, charcoal manufacture, invasive spread of eucalyptus, livestock grazing and expanding human settlements. It occurs in the Réserve Spéciale d’Analamazaotra (Glaw and Vences 2008).
