Source-derived summary

The brown mouse lemur (Microcebus rufus) is a small primate, and like the other mouse lemurs can only be found on the island of Madagascar. They are known also as the rufous mouse lemur, eastern rufous mouse lemur, red mouse lemur, or russet mouse lemur. Its dorsal side is brown or reddish-brown, while ventrally it is a whitish-grey.

The mouse lemurs are among the shortest-lived of primates. The brown mouse lemur has a lifespan of 6–8 years in the wild, although it averages 12 years under human care.

It can be found in rainforests in eastern Madagascar. It is a solitary and nocturnal creature.

Taxonomy

Étienne Geoffroy Saint-Hilaire described this species in 1836 when he described the genus Microcebus, and is sometimes incorrectly cited as the author of this species, but he neglected to assign it a specific epithet. René Lesson would later give the animal a proper taxonomic name as Microcebus rufus. Wilson & Reeder's 2005 mammal checklist Mammal Species of the World recognized Geoffroy as the correct taxonomic authority despite the lack of a taxonomic name.

Editorial summary

The public source identifies “Brown mouse lemur” as species of mammal. This brief keeps that definition visible, then builds a research path around Brown, mouse and lemur.

Editorial reviewUseful for establishing the present vocabulary of the subject while preserving a route back to the evidence on which that vocabulary rests. The current lead gives the account dated anchors—1836, 2005—that can be checked directly. The selected authority fields contribute no independent date. Its value is orientation rather than verdict, with Brown, mouse and lemur providing the first useful test.
Editorial analysis

Why this record matters

A short description can identify a subject without explaining its stakes. For “Brown mouse lemur”, the useful work is to connect “species of mammal” to the records capable of establishing context and consequence.

Evidence profile

The date and method of observation matter as much as the stated conclusion, especially where classification or consensus has changed. The source revision retrieved here is dated May 31, 2026. The linked authority identifier is Q901158. None of the 0 selected statements returned an explicit reference. The first chronological checks are 1836 and 2005.

Critical limits

Scientific names, classifications and consensus can change while older terminology persists in catalogues and historical literature. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.

How to read it

Check terminology, classification and the date of the cited evidence. Scientific names and technical consensus can change while older records retain historical value.
