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
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
