This species is found in southeastern coastal Madagascar. 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. In Andohahela animals were observed at 1,500 m, but were absent at higher elevations (Feistner and Schmid 1999).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. The extent of occurrence (EOO) is estimated to be less than 14,370 km2.
Habitat and Ecology
An inhabitant of subtropical moist lowland and montane forest (up to 1,600 m). The species is believed to be cathemeral and lives in groups ranging from 4 to 7 individuals, sometimes with more than one breeding female. At Kalambatritra Special Reserve and Mandena, individuals exhibit latrine behaviour (repeated group defecation at specific sites); groups defecate in turn, with adults going first followed by juveniles. It is thought that this likely serves some communicatory function, possibly for demarcating territory (Eppley and Donati 2010).
Groups from Mandena have been observed to spend significant amounts of time on the ground, foraging terrestrially on various grass species (Poaceae spp.) within the forest, in open-canopy areas, and within swamp areas (Eppley and Donati 2009, Eppley et al. 2011). These flooded forest and marsh habitats appear to be important for the individuals populating the littoral coastal forest, with groups even observed in the reed marshes along the estuaries by Evahtra.
IUCN Red List Assessment
Red List Category
Red List Criteria
The principal threat is habitat loss due to slash and burn agriculture, illegal timber extraction, charcoal production, and for mining of titanium. Hunting is also a threat, with locals targeting this species as it appears to crop-raid often in agricultural areas.
This species is listed on Appendix I of CITES. This species is known to occur in three national parks (Andohahela, Andringitra and Midongy du Sud), three special reserves (Kalambatritra, Manombo and Pic d' Ivohibe), Tsitongambarika Protected Area, and in the Mandena Conservation Zone, east of Tolagnaro (Feistner and Schmid 1999, Rabarivola et al. 2007, P.C. Wright pers. comm.). As of 2010, this species was not being kept in captivity (I.J. Porton pers. comm.).
Southern lesser bamboo lemur
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. However, it is darker and redder than the eastern lesser bamboo lemur, with a shorter tail and different vocalizations. The type locality is Mandena, and it is believed to inhabit moist lowland and montane forests.
