Range Description

The Red-fronted Brown Lemur is found both in western and eastern Madagascar. In the west, it is known from the Tsiribihina River south at least to the Fiherenana River near Toliara. The limits of its distribution in eastern Madagascar are not as well defined, but it appears to occur from the Onive and Mangoro Rivers south to the Andringitra Massif, the southern limit of its range probably being the Manampatra River, which separates this subspecies from E. cinereiceps. South-east of the Andringitra Massif, there is a 60-km wide hybrid zone between E. rufifrons and E. cinereiceps at the Iantara River (headwaters of the Manampatrana) (Irwin et al. 2005). A small introduced population of Red-fronted Brown Lemurs (hybridized with E. collaris) also inhabits the Berenty Private Reserve in southern Madagascar. Ranges from sea level to 1,670 m.
