New Primate Species Discovered on Madagascar

A Malagasy-German research team has discovered a new primate species in the Sahafina Forest in eastern Madagascar, a forest that had not been studied before. The name of the new species is Gerp’s mouse lemur (Microcebus gerpi), chosen to honor the Malagasy research group GERP (Groupe d’Étude et de Recherche sur les Primates de Madagascar).
Several researchers of GERP visited the Sahafina Forest in 2008 and 2009 to create an inventory the local lemurs. They captured several mouse lemurs, measured them, took photos and small biopsies for genetic studies, and released them again. Proessor Ute Radespiel, Institute of Zoology of the University of Veterinary Medicine Hannover, analyzed the samples and the morphological dataset, and confirmed that the animals from the Sahafina Forest belong to an undescribed species of the small nocturnal mouse lemurs.
“We were quite surprised by these findings. The Sahafina Forest is only 50 km away from the Mantadia National Park in eastern Madagascar, which contains a different and much smaller species, the Goodman’s mouse lemur,” commented Professor Radespiel. In contrast, the Gerp’s mouse lemur belongs to the group of larger mouse lemurs, i.e. has a body mass of about 68g, and is therefore almost “a giant” compared to the Goodman’s mouse lemur (ca. 44g body mass).
The distribution of the Gerp’s mouse lemur is probably restricted to the remaining fragments of lowland evergreen rain forest of this region in eastern Madagascar. Continuing deforestation poses a serious threat for these animals. The researchers from Hanover/Germany and Madagascar published their discovery together in the journal Primates.
