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).

Habitat and Ecology
The behaviour and ecology of this species are poorly known. It was first found in degraded littoral forests dominated by Ravenala madagascariensis and Pandanus spp., which at the most contained only patchy stands of bamboo. It is believed to be diurnal and to live in relatively small groups (Mutschler and Tan 2003).

Reviewer/s
Mittermeier, R.A. & Rylands, A.B. (Primate Red List Authority)

Justification
Listed as Vulnerable as the species has a distribution range of less than 20,000 km², is severely fragmented, and there is continuing decline in the area and quality of habitat within the range of the species coupled with a decline in the number of mature individuals due to hunting.

Threats

Major Threats
The principal threat is habitat loss due to slash-and-burn agriculture (for growing Cannabis), illegal timber extraction, charcoal production, and for mining of titanium. Hunting is also a threat.

Conservation Actions
This species is listed on Appendix I of CITES. This species is reported to occur in two national parks (Andohahela and Midongy du Sud); this is also probably the species in Kalambatritra. Additional survey work is needed to establish the precise range of this species (especially relative to H. griseus to the north) and obtain additional info on biology and ecology.

Southern lesser bamboo lemur

Learn more about this article

The southern lesser bamboo lemur (Hapalemur meridionalis), also known as the southern bamboo lemur, rusty-gray bamboo lemur, and southern gentle lemur, is species of bamboo lemur endemic to southern Madagascar near Tôlanaro. It was originally proposed as a subspecies of the eastern lesser bamboo lemur and is of similar size.[3] However, it is darker and redder than the eastern lesser bamboo lemur, with a shorter tail and different vocalizations.[3] The type locality is Mandena, and it is believed to inhabit moist lowland and montane forests.[3]

The southern lesser bamboo lemur is further supported as a separate species by recent mitochondrial DNA research.[4]
