Ramanantsoavana's woolly lemur (Avahi ramanantsoavanai), also known as Ramanantsoavana's avahi or the Manombo woolly lemur, is a species of woolly lemur native to southeastern Madagascar. It weighs about 1 kg. It was originally considered a subspecies of the southern woolly lemur (A. meridionalis), A. m. ramanantsoavana, but was elevated to a separate species in 2006 based on molecular, phenotypic and morphological data.
