Taxonomy [top]

Kingdom Phylum Class Order Family
ANIMALIA CHORDATA MAMMALIA PRIMATES LEMURIDAE

Scientific Name: Hapalemur meridionalis
Species Authority: Warter, Randrianasolo, Dutrillaux & Rumpler, 1987
Common Name/s:
English Rusty-gray Lesser Bamboo Lemur, Southern Grey Bamboo Lemur, Southern Lesser Bamboo Lemur
Taxonomic Notes: Although this species was not recognized as distinct by Groves (2001), who retained it as a subspecies of H. griseus, its distinct status is supported by cytogenetic and molecular data (Fausser et al. 2002).

Assessment Information [top]

Red List Category & Criteria: Vulnerable B1ab(iii,v) ver 3.1
Year Published: 2008
Date Assessed: 2008-06-30
Assessor/s: Andrainarivo, C., Andriaholinirina, V.N., Feistner, A., Felix, T., Ganzhorn, J., Garbutt, N., Golden, C., Konstant, B., Louis Jr., E., Meyers, D., Mittermeier, R.A., Perieras, A., Princee, F., Rabarivola, J.C., Rakotosamimanana, B., Rasamimanana, H., Ratsimbazafy, J., Raveloarinoro, G., Razafimanantsoa, A., Rumpler, Y., Schwitzer, C., Thalmann, U., Wilmé, L. & Wright, P.
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.

Geographic Range [top]

Range Description: 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).

Population Trend: Decreasing

Habitat and Ecology [top]

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).
Systems: Terrestrial

Threats [top]

Major Threat(s): 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 [top]

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.
