Like several other mouse lemurs, like the brown mouse lemur (Microcebus rufus), it is a small primate that has a brown dorsal side and a whitish grey for its ventral side of the body. All lemurs live in Madagascar. This species was discovered in 1994.

The island of Madagascar is located off the southeastern coast of Africa. All species of lemur are indigenous to the island. The Golden brown mouse lemur is isolated in the forest reserve of Ankarafantsika National Park, a dry deciduous forest located in northwestern Madagascar. It shares the habitat with the gray mouse lemur (M. murinus), a sympatric species. Within the habitat that which both the golden brown lemur and gray mouse lemur live, they occupy two very different niches showing divergent regional distribution and different population density patterns. The golden brown mouse lemur prefers habitat areas in lower latitudes that are humid and in close proximity to water resources. Whereas the gray mouse lemur populations increase with altitude and are located in drier habitats away from water sources. The golden brown mouse lemur’s habitat is well dispersed among sexes and family groups, showing little sign of intra or interspecific competition among overlapping territories. which means they sleep during the day and search for food at night. According to National Geographic, golden brown mouse lemurs consume "insects, fruit, flowers, and other plants." They are known to be mostly frugivorous primates (primarily fruit eating), but they can be omnivorous as well. The brown mouse lemur is able to store "thirty five percent of their body weight" in the form of fat. This fat is stored in the lemur's hind legs and tail and is used for energy when food sources are scarce.

The golden brown mouse lemur has been categorized as a separate species based on morphology Its dorsal side is golden brown, and yellowish white ventrally. It has a white stripe running from the lower forehead to the muzzle. It weighs depending on the season, and is similar in appearance to the gray mouse lemur, though it has a longer, thinner tail. It is unable to store fat in its tail like other mouse lemurs. It travels through the forest by leaping, unlike the gray mouse lemur. It is a nocturnal species, and builds its nests in dense patches of vines or dead leaves.

According to Matthew Esser, "Sexual maturity is reached after one year of age." The brown mouse lemur also has an established mating ritual. A male will use "soft squeak calls and tail lashing" to signal the female. The female shows that she is willing to mate by "ano genital rubbing and mouth wiping." When the mating has ended, the female will making a threatening sound. Some of the males who are more dominant will have multiple mates. "Brown mouse lemurs mate between September and October." The offspring are usually born between November and December. There are usually one to three young for each litter; females are capable of having one to two litters each year. In the winter months following their birth, the males of the species leave the areas where they were born. Although deforestation seems to benefit the species in one specific location, the overall effects of deforestation lead to disruption in biodiversity, population density and dispersal and decreased genetic diversity. IUCN red list website states that, "The principal threat to this species is habitat loss due to slash and burn agriculture." They are also threatened by natural predators in their habitat. Some of the well known predators are "fossa (Cryptoprocta ferox), ring tailed mongoose (Galidia elegans), owls (Strigiformes), and Madagascar harrier hawk (Polyboroides radiatus)." Some say that brown mouse lemurs could be influential in spreading the seeds of plants and fruits they eat. As a result of deforestation they are at risk of extinction according to the Convention on International Trade in Endangered Species (CITES).
