Specimens were first collected in December 2003, and its discovery was announced in 2013 along with the Anosy mouse lemur (Microcebus tanosi).

At the time, he captured three mouse lemurs at Marohita Forest in the Toamasina Province of eastern Madagascar, near the village of Marolambo.

These were prepared as biological specimens, including skins, skulls, and tissue samples, with the required permits from the government of Madagascar.

Its species name, marohita, refers to the forest in which it was found and means "many views" in the Malagasy language.

[6] The back coat of the Marohita mouse lemur is rufous and has a mid-dorsal stripe that is difficult to discern.

[7] Due to extensive habitat degradation within Marohita Forest between 2003 and 2012, the International Union for Conservation of Nature (IUCN) evaluated the Marohita mouse lemur as Endangered at a workshop for the IUCN Red List held at Madagascar's capital, Antananarivo, in July 2012, nearly a year prior to the publication of its formal description.
