Species limits and distribution of the malagasy carnivoran genus eupleres (Family Eupleridae)

摘要

A review was conducted of members of the endemic Malagasy carnivoran genus Eupleres (family Eupleridae) based on published and unpublished records and museum specimens. Classically, one species has been recognized in this poorly known genus - E. goudotii, divided into two geographical forms with non-overlapping distributions: E. g. goudotii distributed in the mesic forests of the east and E. g. major found in the dry areas of the northwest. Drawing on external and craniodental comparisons, we demonstrate that these two forms are highly distinctive morphologically and can be readily distinguished from each another. Furthermore, there is some evidence that they both can occur on the slopes of Montagne d'Ambre in the far north of the island. On this basis, we recognize these taxa as distinct species, E. goudotii and E. major.
