Dorsale stekels (totaal): 1; Dorsale zachte stralen (totaal): 6; Anale stekels 3; Anale zachte stralen: 8. Mouth is used as a sucking disc to hold its position in fast flowing waters. Gut length is less than standard length and the mandibular teeth are used to scrape invertebrates from stones.

Biologie     Verklarende woordenlijst (b.v. epibenthic)

Found in shallow rocky runs and riffles of clear rivers, at an altitude of 900-1200 m above sea level, and depths from 0.2 to 0.4 m (Ref. 52116). Feeds on invertebrates such as mayfly nymphs and caddis fly, blackfly or midge larvae grazed from rocks. Oviparous (Ref. 205). Breeds in summer (Ref. 7248). Distribution in southern Africa is restricted and may be threatened by alteration of its habitat (Ref. 52116).
