N2 - Kapuasia falaris, new species, is described from the Barito drainage on Borneo. It is distinguished from its only congener K. maculiceps in having a conspicuous colour pattern of 3–7 regular black bars on the flank, on a white background; in males, presence of a suborbital flap and vertical skin flanges on the dorsal surface of the pectoral fin between the branched rays; in males, pectoral axillary lobe cylindrical, with pointed posterior extremity, usually separate from skin of flank by a deep groove, often with a second similar lobe above the groove. The shape of this lobe is apparently unique among Southeast Asian species of nemacheilids, as well as the shape of the suborbital flap (globulous, at some distance below the eye, with a deep vertical groove from the flap to the eye). The strongly upwards curled pectoral fin, appearing with an almost vertical orientation in life, is apparently unique among Southeast Asian nemacheilids.
