ResumoFlying lemurs, or colugos, are among the most enigmatic mammals. They have the most extensive gliding membrane of any volant mammal (Figure 1A), allowing them to traverse distances up to 136 meters [1Lim N.T.-L. Colugo: The Flying Lemur of South-east Asia. Draco Publishing and Distribution, Singapore2007Google Scholar]. Current taxonomy recognizes just two colugo species, each assigned to a unique genus: the Sunda colugo (Galeopterus variegatus) and the Philippine colugo (Cynocephalus volans) [2Stafford B.J. Order Dermoptera.in: Wilson D.E. Reeder D.M. 3rd Edition. Mammal Species of the World. Volume 1. The John Hopkins University Press, Baltimore2005: 110Google Scholar]. Because the evolutionary history of colugos is poorly known we undertook the first study to examine genetic variation in the broadly distributed Sunda colugo. Our results, combined with morphological data, provide compelling evidence that mainland, Javan, and Bornean colugo subspecies may be better recognized as distinct species, potentially tripling species diversity in the genus Galeopterus.
