The White-collared Brown Lemur (Eulemur albocollaris) is a medium-sized prosimian in the order Primates, a cathemeral species of lemur in the Lemuridae family. It is only found in southeastern Madagascar, from the Manampatrana River south to the Mananara River.
This species was formerly listed as a subspecies of the Common Brown Lemur (Eulemur_fulvus) until elevated in 2001 and accepted by the IUCN/SSC Conservation Breeding Specialist Group (CBSG) in 2002. However, recent genetic and field studies still support subspecies status.
In 2005, satellite imagery estimates showed approximately 700 km2 of total remaining habitat within its geographic range.
