ABSTRACT
Three forms of Mastomys (Rodentia, Muridae) originating from Senegal (2n = 32), Central African Republic (Bangui, 2n = 32) and Sudan (2n = 38) were compared after R-banding. The number of chromosomal rearrangements, inversions, translocations and fusions differentiating their karyotypes strengthens the hypothesis that they correspond to 3 distinct species. A phylogenetic scheme is proposed.
Keywords: cytogenetic; Mastomys.
