Abstract
- Among the African Murinae (Rodentia, Muridae), the Praomys complex, whose systematics has been studied by different approaches, has raised numerous taxonomic problems. Different taxa, namely Praomys, Mastomys , Myomys and Hylomyscus have been considered either as separate genera or subgenera of Praomys . In order to understand the relationships within the Praomys complex and to test the monophyly of the genus Praomys , a cladistic analysis was conducted, based on morpho-anatomical factors involving different species of Praomys , Mastomys , Myomys and Hylomyscus. The results indicate that the Praomys complex is monophyletic, as are the genera Hylomyscus , Mastomys and Myomys , whereas the genus Praomys appears paraphyletic. Indeed, a group of species including Praomys jacksoni was found to be more closely related to the genera Mastomys and Myomys than to a Praomys tullbergi -group. The biotopes and the distribution areas of the species were mapped on the phylogeny. It appears that the different clades each present a relative ecological cohesion and are arranged according to a gradient from closed to open habitats. From there, an evolutionary scenario is proposed for the emergence of the different clades and species of the genus Praomys sensu stricto. [ABSTRACT FROM AUTHOR]
