Justification: Widespread in upper catchments from the Incomati River, South Africa north into the Limpopo River in southern Zimbabwe. In suitable habitats it is usually abundant. In parts of its range around Johannesburg and Pretoria in South Africa it seems to have become extinct including its type locality presumably due to varied pollution and flow modifications from industries and human settlements. Despite threats and local extinctions the species does not qualify for endangered categories. |

Geographic Range [top]
| Range Description: | Incomati River system in Swaziland north to the Limpopo system. Possibly present in the northern Limpopo tributaries in southern Zimbabwe. However, many northern museum records for this species appear to be incorrect. |

Habitat and Ecology [top]
| Habitat and Ecology: | Typically occurs in riffle habitats, bases of water falls in fast flowing often shallow water. |
| Systems: | Freshwater |
Threats [top]
| Major Threat(s): | Degradation of habitats is the major threat and the species has disappeared from its type locality around Pretoria, South Africa. Threats are however, localised around major settlements and the species is widely distributed. |
Conservation Actions [top]
| Conservation Actions: | Improved conservation of aquatic habitats through river health programmes and conservancies is perhaps the best way to improve the conservation of these species. |
