The giant mouse lemurs are members of the strepsirrhine primate genus Mirza. Two species have been formally described; the northern giant mouse lemur and Coquerel's giant mouse lemur. Like all other lemurs, they are native to Madagascar, where they are found in the western dry deciduous forests and further to the north in the Sambirano Valley and Sahamalaza Peninsula. First described in 1867 as a single species, they were grouped with mouse lemurs and dwarf lemurs. In 1870, British zoologist John Edward Gray assigned them to their own genus, Mirza. The classification was not widely accepted until the 1990s, which followed the revival of the genus by American paleoanthropologist Ian Tattersall in 1982. In 2005, the northern population was declared a new species, and in 2010, the World Wide Fund for Nature announced that a southwestern population might also be a new species.
The northern giant mouse lemur, or northern dwarf lemur, is a species of lemur discovered in 2005. They are part of the primate order, and classified in the family Cheirogaleidae. Previously, both populations of giant mouse lemurs were believed to belong to one species. The northern giant mouse lemurs are small nocturnal lemurs endemic to Madagascar. They weigh about 300 grams (11 oz), and have long, bushy tails and relatively small ears. Their large testicles are an indication of their promiscuous copulation system. These lemurs have been found to use communal sleeping nests including multiple males, which is an uncommon behaviour in lemurs.
The black lemur is a species of lemur from the family Lemuridae. Like all lemurs, it is endemic to Madagascar. Originally, the species was thought to have two subspecies, Eulemur macaco macaco and Eulemur macaco flavifrons, both of which were elevated to species status by Mittermeier et al. in 2008 to Eulemur macaco and Eulemur flavifrons respectively. The most startling difference between the two species is the eye colour; Eulemur flavifrons, the blue-eyed black lemur, has blue eyes, while Eulemur macaco, the black lemur, has brown or orange eyes, and also has ear tufts.

The Lavasoa dwarf lemur is a small, nocturnal strepsirrhine primate and a species of lemur that is endemic to three small, isolated patches of forest on the southern slopes of the Lavasoa Mountains in southern Madagascar. Fewer than 50 individuals are thought to exist. Its habitat lies in a transitional zone between three ecoregions: dry spiny bush, humid littoral forest, and humid forest. First collected in 2001 and thought to be a subpopulation of the furry-eared dwarf lemur (C. crossleyi), it was not formally described until 2013. It is one of six species of dwarf lemur, though the research that identified it also suggested the existence of many more new species.
The Sambirano region, also known as the Sambirano domain, is a biogeographic region of northwestern Madagascar. It has a distinctive lowland climate with year-round rain, differing from the rest of seasonally-dry western and northern Madagascar. The climate supports humid lowland rainforests, with greater similarity to those of eastern Madagascar than the dry deciduous forests characteristic of the Madagascar's western lowlands.
