Description: In a recent survey of populations of the Korean torrent catfish Liobagrus, a distinctive species was discovered from the Geum River and its tributaries flowing into the western coast of Korea, and here described as a new species, L. geumgangensis sp. nov. It is distinguishable from other congeners by a combination of the following characters: I, 8 pectoral fin-rays; 52–56 caudal-fin rays; a relatively short occiput to dorsal-fin origin distance (6.9–9.8% SL); a short pelvic-fin insertion to anal-fin origin distance (11.9–17.3% SL); a long dorsal-fin base (10.6–13.5% SL); 8–9 gill rakers; 5–8 serrations on the pectoral fin (Kim S-h, et al. 2023). Habitat: Liobagrus geumgangensis is restricted to some rivers flowing to the west coast of South Korea, Geum River and upper stream of Mangyeong River (Kim S-h, et al. 2023). Colouration: In life the body is generally brownish yellow, fading to light yellow on ventral surface, without any distinct markings. All barbels pale gray. All fins with similar colour to body, without deep yellow outer margins (Kim S-h, et al. 2023). Etymology: The species is named after the Geum River (Geumgang in Korean), the type locality.
