Fangfangia spinicleithralis, new genus, new species, is described from peat swamp forest habitats in Kalimantan Tengah, Borneo, Indonesia. It differs from all other cyprinids in having the anteroventral tip of the left cleithrum projecting into a strong anteriorly directed spine and a pointed posteriorly directed spine at the posteroventral aspect of each cleithrum. In addition, it can be diagnosed by the following characters: the base of the dorsal hemitrich of the first pectoral-fin ray with serrated margin, multicuspid pharyngeal teeth, ventrally directed lateral processes on vertebra 1, the high number of procurrent caudal-fin rays (14-18 dorsally, 11-15 ventrally), absence of scales with the exception of six or seven tubular lateral line ossicles, and the greatly elongated middle radials in the anal fin, which may reach half the length of proximal radials.
