Rationale (Changed due to Same category and criteria)

This species is widespread and considered to be relatively common. At present, there are no known substantial threats so it is considered Least Concern.

Distribution

Endemic to sub-Saharan Africa, from West Africa (e.g. Senegal, Guinea) eastwards to Sudan and southwards to South Africa, but absent in Gabon and peripheral to the Congo basin of Democratic Republic of the Congo (Hughes 1985). Widespread in the southern Africa, including South Africa, Eswatini (Swaziland), Mozambique, Zimbabwe, Botswana and Namibia. In South Africa, it occurs in four disjunct populations a) the Eastern Cape Province, b) in KwaZulu-Natal, Mpumalanga, Gauteng, Limpopo, North-West provinces, c) western margin of the Northern Cape Province, and d) eastern margin of the Northern Cape Province and into Northwest Province (Bates et al. 2014, Engelbrecht 2017).
