Abstract
Rasbora lacrimula, new species, is distinguished from all other species of the genus by having very small tubercles forming a kind of granulated ‘crest’ along the dorsal midline posterior to the dorsal fin, continued onto the upper edge of the caudal fin, and a colour pattern with a faint narrow midlateral stripe ending in longitudinally orientated, teardrop-shaped blotch. It is presently known only from the Mahakam drainage in Kalimantan Timur, Borneo, Indonesia.
