Hypergastromyzon eubranchus sp.nov. is described from the Lupar basin of Sarawak, Malaysian Borneo. It differs from the only other known species of Hypergastromyzon, H. humilis, from the Kapuas basin of western Borneo, in having a very large gill opening instead of a greatly reduced one, 23-25 instead of 28-30 branched pectoral fin rays, and pelvic fins incompletely rather than completely united to each other posteriorly.
