Issue
There has been confusion between G. dembeensis, G. johnstonii and G. hindii. G. johnstonii is a junior synonym of G. dembeensis, but G. hindii differs in having a fully scaled predorsum, belly and chest; it does, however, share two important meristic and morphometric features with G. dembeensis: high number of scales in lateral line and vent located away from anal fin (Ref. 81639).

Diagnosis: Garra dembeensis is distinguished from African congeners by the following combination of features: well-developed disc; between 0 and 4 predorsal scales anterior to dorsal fin; asquamate chest, belly and postpelvic region; intestine of medium length; ad moderately sized gas bladder (Ref. 58532).
Commonly found in rapid parts of rivers and also on wave-washed rocky shores of Lake Victoria (Ref. 4903). Adheres to stones in swift water (Ref. 28714). Feeds on epilithic algae and lithophilic insects (Ref. 12526), scraped from the surface of rocks (Ref. 4903).
