Goodman's mouse lemur (Microcebus lehilahytsara) is a species of mouse lemur from the region near Andasibe in eastern Madagascar. It is thought to have diverged from other mouse lemurs in the region about 2 million years ago. The species is named in honor of primatologist Steven M. Goodman. "Lehilahytsara" is a combination of the Malagasy words which mean "good" and "man". The finding was presented August 10, 2005, along with the discovery of the northern giant mouse lemur (Mirza zaza) as a separate species.
