Distribution of sibling species of the Praomys (Mastomys) natalensis group in Rhodesia (Mammalia: Rodentia)



The taxon Praomys (Mastomys) natalensis, the multimammate mouse, comprises at least two biological species in Rhodesia. Species-specific haemoglobin phenotypes which were previously documented for sympatric populations near Salisbury are shown to apply throughout Rhodesia. Several areas of sympatry were revealed which encompassed various habitats. No hybrids for diploid number or haemoglobin phenotype were found.
