 Abstract
 Kapuasia, new genus, is created to accommodate ‘Nemacheilus’ maculiceps, from the Kapuas drainage on Borneo. It is distinguished by the presence of a large suprapectoral flap above the pectoral fin, and its unique lip morphology. The lower lip has a continuous anterior edge, and its median part has 8–10 ridges on each side, radiating at the anterior extremity, across the whole lip, resulting in a crenulated inner edge of the lip. 

Key words. Cobitoidei, Nemacheilidae, Schistura, Borneo, stone loach
