The Zambesiaca area includes Botswana, Caprivi (Namibia), Zambia, Malawi, Mozambique and Zimbabwe. One apodan and 113 anuran species are currently recognised in the area. The area does not constitute a distinctive zoogeographical unit; agglomerative classification suggests it includes a section of an East African lowland fauna, an adjoining upland (part Afromontane) complex, west of which is a mosaic of species clusters on the interior plateaux. This classification is tested by means of a transect. Virtually the whole area is included in the ranges of five species, while 24 species and sub­species are endemic, mostly localised on the eastern uplands. These uplands have the greatest species diversity (total of 79 species and subspecies), receiving subtraction margins of the eastern and the western plains faunas in addition to the upland complex. The eastern lowland carries the largest homo­geneous fauna of 38 species (including 2 subspecies). Relationships between species ranges and environmental patterning show complexities which at present are for the most part not clearly iden­tified and understood; temperature appears to be of particular underlying importance.
