Voalavo antsahabensis
''Voalavo antsahabensis'', also known as the eastern voalavo, is a rodent in the family Nesomyidae which occurs in the Anjozorobe forest of eastern Madagascar. Although surveys before 2002 failed to record the species, it is common in some places. However, it is threatened by habitat loss because of slash-and-burn agriculture. The species was formally described in 2005 and is most closely related to the only other species of ''Voalavo'', ''Voalavo gymnocaudus'' from northern Madagascar.
The two species of ''Voalavo'' are only subtly different in morphology. With a body mass of 20.7 to 22.6 g (0.73 to 0.8 oz), ''V. antsahabensis'' is a small rodent. It has a longer tail than ''V. gymnocaudus'', as well as a longer rostrum (front part of the skull) and diastema (gap between the incisors and molars), but shorter molar rows. The two species also differ in details of the configuration of the palate.
==Taxonomy==
''Voalavo antsahabensis'' was first recorded in 2002,〔 when three individuals were captured in Madagascar's Anjozorobe forest. In 2005, the species was formally described by Steven Goodman and colleagues as ''Voalavo antsahabensis'', the second species in the genus ''Voalavo''. The only previously known species, ''Voalavo gymnocaudus'', occurs further to the north, in the Northern Highlands.〔Goodman et al., 2005, p. 863〕 The sequences of the cytochrome ''b'' gene differ by about 10% in these two species.〔Goodman et al., 2005, p. 871〕 The specific name, ''antsahabensis'', derives from the name of the village of Antsahabe, which is near the place where the holotype was found.〔Goodman et al., 2005, p. 870〕 The common name "Eastern Voalavo" has been used for this species.〔
