is locally common within its range and much of its distribution occurs in protected nature reserves. However, the species is a habitat specialist (fresh water stream beds with intermittent flow) at above 1000 m and is only known from an area less than 500 km2. We therefore assess this species to be Rare under the South African Red list categories and criteria (EOO, AOO;
