| History: |
|
|||
| Range Description: | This species is endemic to the island of Madagascar. The type specimen for this species was collected adjacent to Lac Ravelobe, from which its scientific name is derived. Based on morphological measurements, Zimmermann et al. (1997, 1998) concluded that two species of mouse lemur inhabited the forests of Ankarafantsika in north-western Madagascar, where M. ravelobensis is now known to occur sympatrically with M. murinus. It is also known from the Bongolava Classified Forest and Mariarano Classified Forest (Mittermeier et al. 2008). Sea-level to 500 m. |

| Population: | Common in Ankarafantsika. |
| Population Trend: |
Decreasing
|
| Habitat and Ecology: | This species inhabits dry deciduous lowland forest and can be observed even in degraded patches. It appears to prefer forests with a lower canopy height and more lianas than those inhabited by M. murinus, and also uses tree holes less often than that of other species. |
| Systems: | Terrestrial |
| Major Threat(s): | The major threat is habitat loss due to slash-and-burn agriculture and seasonal bushfires. The species also may be susceptible to predation from feral carnivores and invasive non-endemic carnivores. |
| Conservation Actions: | This species is listed on Appendix I of CITES. Ankarafantsika National Park is the only protected area in which it is confirmed to occur. No specimens are reported in captivity at this time (ISIS, 2007). Additional survey work is needed to determine the full extent of the species' range. Serious consideration should be given to establishing a protected area that includes the Mariarano Classified Forest. |
