Rationale
(Changed due to Same category and criteria)
This is a widespread species with no known major threats and it is unlikely to be declining fast enough to qualify for listing in a threatened category. It is therefore assessed as Least Concern.
Distribution
This species has been recorded from South Africa to Kenya and Uganda. A female record from the Democratic Republic of Congo might also be this species. In southern Africa, this species is widespread in rivers, except for in the arid southwest (Kalahari and Namibia) and the Cape.
Destruction of gallery forest, groundwater abstraction and pollution are threats to this species overall. In South Africa, natural catastrophes appear synergistic with urbanisation in northern KwaZulu-Natal, and invasive alien trees may also be a threat alongside water extraction for agricultural purposes (Samways 2006).
Uses and trade
This species is not used.
Conservation
In South Africa, further searches for this species are needed, especially in the Waterberg and in KwaZulu-Natal, where it has not been recorded since 1960 (Samways 2006). Monitoring of the Sabie River population is also required (Samways 2006). No information is available on conservation measures in place or planned elsewhere in its range.
