ABSTRACT. A new river shark, Glyphis fowlerae sp. nov., is described from 14 type specimens from Malaysian Borneo, including 13 specimens collected in freshwater from the vicinity of Kampung Abai in the lower reaches of the Kinabatangan River, Sabah. Glyphis fowlerae differs from other members of the genus
by a combination of vertebral counts, dentition, coloration and morphology, particularly in the comparative heights of the dorsal fins. A second, rarely collected species of Glyphis from Sarawak (Malaysian Borneo) is also compared (based on colour images) to the new species and its status discussed. One of the syntypes
of Glyphis gangeticus, described from India, is designated as a lectotype for that species.
