Popis:	Four sympatric forms of the genus Garra (Cyprinidae) differring in external morphology are reported from the middle reaches of the Sore River belonging to the White Nile system in southwestern Ethiopia. Additionaly, two Garra specimens exhibiting unusual morphology are reported from the same river. One of them posseses ‘rubber lips’, a morphological modification previously unknown for the genus, another exhibits the morphological characters indicating its predatory feeding habits. The reasons to consider the forms of Garra from the Sore River as a presumptive species flock are briefly discussed.
