This species is endemic to the island of Madagascar and is the southernmost of the bamboo lemurs. The type locality is the forestry station of Mandena, located approximately 10 km north of Tolagnaro in far southern Madagascar (Warter and Tattersall 1994). The precise range is a little unclear, but it ranges at least from Andohahela north to the Mananara River. Rabarivola et al. (2007) noted that an animal from Atsimo appeared to be a heterozygote between this species and H. griseus. Upper elevation limit unclear as animals from 1,600 m on the Andringitra Massif are now either H. meridionalis or hybrids between H. griseus and H. meridionalis).
