Rationale
(Changed due to Same category and criteria)
This is a widespread species with no known major widespread 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 Kenya to Cameroon and south to South Africa. In southern Africa, this species is recorded as P. brunneus and it is known from rivers in all countries (Zambezi, Okavango, Limpopo and Kunene River basins), except for Lesotho and Swaziland. There are only a few records from South Africa.
The major threats to this species are habitat loss through drainage and deforestation of swampy habitats caused by agriculture and wood extraction, as well as water pollution.
Uses and trade
This species is not used.
Conservation
No conservation measures are known but research into the population size and range, biology and ecology, habitat status and threats, and monitoring of the population trend would be valuable.
