ARTICLE IN PRESS www.elsevier.de/mambio Original investigation The description of a new species of Myzopoda (Myzopodidae: Chiroptera) from western Madagascar By S.M. Goodman, F. Rakotondraparany and A. Kofoky Field Museum of Natural History, Chicago, USA and WWF, Antananarivo, De´partement de Biologie Animale, Universite´ d’Antananarivo, Antananarivo, Madagasikara Voakajy, Antananarivo, Madagascar Receipt of Ms. 6.2.2006 Acceptance of Ms. 2.8.2006 Abstract A new species of Myzopoda (Myzopodidae), an endemic family to Madagascar that was previously considered to be monospecific, is described. This new species, M. schliemanni, occurs in the dry western forests of the island and is notably different in pelage coloration, external measurements and cranial characters from M. aurita, the previously described species, from the humid eastern forests. Aspects of the biogeography of Myzopoda and its apparent close association with the plant Ravenala madagascariensis (Family Strelitziaceae) are discussed in light of possible speciation mechanisms that gave rise to eastern and western species. r 2006 Deutsche Gesellschaft fu¨r Sa¨ugetierkunde.

A considerable num- limits (e.g., Olson et al. 2004; Yoder et al. ber of new small mammal and primate 2005). The bat fauna of the island is no species have been described in recent years exception – until a decade ago these animals (Goodman et al. 2003), and numerous remained largely under studied and ongoing other mammals, known to taxonomists, surveys and taxonomic work have revealed await formal description. Much of this that they may be something on the order of recent information is based on renewed 30% richer in species than noted in the most interest in biological inventories of recent treatment of this group (Peterson et al. the remaining forested zones of the island 1995). As with other mammals, in certain and the associated systematic studies of cases new species of bats are immediately specimens obtained during these surveys.
