Red List Category & Criteria: Data Deficient 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 Data Deficient as the taxonomic and geographic limits of the species are now unclear, with resulting lack of clarity on population status. However, given known threats and clarity on the distribution range, the species may warrant listing as threatened in future.
History:
1994 Rare (Groombridge 1994)
1990 Rare (IUCN 1990)
1990 Rare (IUCN 1990)
1988 Insufficiently Known (IUCN Conservation Monitoring Centre 1988)
1986 Insufficiently Known (IUCN Conservation Monitoring Centre 1986)

Geographic Range [top]

Range Description: With the recent descriptions of several new species of Lepilemur from eastern Madagascar, the range of L. mustelinus has become unclear. Based on the interpretation of the distributions of Louis et al. (2006), this species now occurs north of the Mangoro and Onive Rivers (with M. betsileo apparently occurring to the south) north at least to the Onibe, and possibly further. Louis et al. (2006) assigned the sportive lemurs from Mananara-Nord, south of the Antainambalana River, to L. seali. In the past these have been attributed to L. mustelinus. The Maningory is here arbitrarily assigned as the limit between L. mustelinus and L. seali, but clearly this requires further investigation.

Population [top]

Population: Based on current understanding of the species' range, the taxon remains widespread and apparently common to uncommon throughout its eastern rain forest range.
Population Trend: Unknown

Habitat and Ecology [top]

Habitat and Ecology: An inhabitant of the eastern rainforests. Given the taxonomic confusion that exists between this species and other newly described species of Lepilemur, it is difficult to ascribe particular biological paramaters to one or the other forms with any certainty.
Systems: Terrestrial

Threats [top]

Major Threat(s): The major threat is likely to be habitat loss due to slash and burn agriculture. Hunting pressure in this region is high, and includes hunting with spears, and by chopping down trees known to have nest holes.

Conservation Actions [top]

Conservation Actions: This species is listed on Appendix I of CITES. It occurs in two national parks (Mantadia and Zahamena), two special reserves (Analamazaotra and Mangerivola), and two strict nature reserves (Betampona and Zahamena). Further work is now urgently needed to clarify the distribution and taxonomic limits of the recently described Lepilemur species.
