  • Conservation : Skelton, 1977 .
  • Current distribution known : occurs in three isolated river systems (the Sundays, Swartkops and Baakens) which discharge into Algoa Bay near Port Elizabeth. Remnant populations of this species are highly fragmented, persisting in only a few less degraded upland tributaries that have not been invaded by alien species .

  • Habitat / home range : inhabits relatively undisturbed clear water mountain streams with cobbles, pebbles and boulders as the predominant substratum. During the dry season, the streams recede into a series of isolated pools that are fed by groundwater. The species is thus adapted to the extreme fluctuations in flow, water temperature and water quality which are characteristic of these intermittent streams .
