Giant mouse lemur

The giant mouse lemurs (members of the genus Mirza) are a genus of strepsirrhine primates. Two species have been formally described; the northern giant mouse lemur (Mirza zaza) and Coquerel's giant mouse lemur (Mirza coquereli). 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.
