Scientists from Mainz and Antananarivo describe Lavasoa Dwarf Lemur as new primate species

The island of Madagascar harbors a unique biodiversity that evolved due to its long-lasting isolation from other land masses. Numerous plant and animal species are found solely on Madagascar. Lemurs, a subgroup of primates, are among the most prominent representatives of the island's unique fauna. They are found almost exclusively on Madagascar. The only exceptions are two species of the genus Eulemur that also live on the Comoros Islands, where they probably have been introduced by humans. Thanks to extensive field research over the past decades, numerous previously unknown lemur species have been discovered. Dwarf lemurs in turn received relatively little attention to date and the diversity within this genus is still not well known. Researchers of the universities of Mainz and Antananarivo have investigated lemur populations in southern Madagascar. Based on fieldwork and laboratory analyses, they now identified a previously unknown species of dwarf lemur. The findings of the research project have recently been published in the journal Molecular Phylogenetics and Evolution.

"Together with Malagasy scientists, we have been studying the diversity of lemurs for several years now," said Dr. Andreas Hapke of the Institute of Anthropology at Johannes Gutenberg University Mainz (JGU). "It is only now that we were able to determine that some of the animals examined represent a previously unknown species." The newly described Lavasoa Dwarf Lemur (Cheirogaleus lavasoensis) inhabits three isolated forest fragments in the extreme south of Madagascar. According to current knowledge, it does not occur outside this area. The exact population size is unknown. Preliminary estimates indicate that there are less than 50 individuals remaining. The Lavasoa Dwarf Lemur is thus rare and extremely endangered.

The lifestyle of dwarf lemurs makes them extremely difficult to study as these nocturnal forest dwellers often remain in the upper parts of the
