Summary. – The variable hinged terrapin, Pelusios rhodesianus (Family Pelomedusidae), is a moderate-sized species that inhabits weedy shallow dams and backwaters from Lake Victoria south to KwaZulu-Natal, South Africa. The populations in the main part of the species’ range seem to be in good shape and the construction of storage dams provides additional suitable habitats for P. rhodesianus. However, some of the peripheral southern populations in South Africa (KwaZulu-Natal) are threatened or extinct.

Distribution. – Angola, Botswana, Burundi, Congo (DRC), Mozambique, Namibia, Rwanda, South Africa, Tanzania, Uganda, Zambia, Zimbabwe. Central and Eastern Africa from Congo in the northwest to Lake Victoria region in the northeast, south to eastern South Africa.

Synonymy. – Pelusios nigricans rhodesianus Hewitt 1927, Pelusios subniger rhodesianus, Pelusios rhodesianus, Pelusios castaneus rhodesianus, Pelusios rhodesianus rhodesianus.

Subspecies. – None recognized. Morphology suggests possible north-south geographic variation.

Status. – IUCN 2007 Red List: Least Concern (LR/lc) (assessed 1996, needs updating); CITES: Not Listed.

Distribution:

Distribution of Pelusios rhodesianus in Africa. Red points = museum and literature occurrence records based on Iverson (1992) plus more recent and authors’ data; green shading =  projected distribution based on GIS-defined hydrologic unit compartments (HUCs) constructed around verified localities and then adding HUCs that connect known point localities in the same watershed or physiographic region, and similar habitats and elevations as verified HUCs (Buhlmann et al., unpubl. data), and adjusted based on authors’ data.
