This species occurs only in southeastern Madagascar in a thin strip of tropical moist lowland forest (sea level to 900 m) that runs from the Andringitra Massif south to the Mananara River. Two isolated populations of this species occurs in the Manombo Special Reserve and in Mahabo Forest south of Farafangana; a small coastal plain population may also occur at Vohipaho, south of the Mananara River, although genetic analyses are needed to confirm whether this is E. cinereiceps or E. collaris. Recent analyses of Landsat imagery estimate that total habitat remaining within this species’ range is less than 700 km2 (Irwin et al. 2005). South-east of the Andringitra Massif, there is a 45 km wide hybrid zone between E. rufifrons and E. cinereiceps, centred at the headwaters of the Manampatrana.
