Description: A new torrent catfish species, Liobagrus chengduensis sp. nov., is described from the Xihe River, a tributary of the Minjiang River, Qionglai City, Chengdu City, Sichuan Province, China. It can be distinguished from all other congeneric species by a unique combination of the following characters: 3–4 serrations on posterior edge of pectoral-fin spine; anal fin with 15–16 rays; upper jaw obviously shorter than lower jaw; caudal fin rounded, with 42–44 rays; vertebral column with 36–37 post-Weberian elements; anus close to pelvic-fin insertion; adipose fin posteriorly continuous with caudal fin, with marked incision at confluence. Habitat: The new species is nocturnal and benthic and inhabits the bottom of upstream running waters with pebble substrates, together with L. aff. kingi and L. pseudostyani, while L. marginatus inhabits in the main stream of the Minjiang River (Zhong-Guang Chen et al. 2022). Colouration: Body generally brownish yellow; all fins lacking well-defined light-colored margins, with color fading towards edge (Zhong-Guang Chen et al. 2022). Etymology: The species is named after Chengdu City, its type locality. The proposed English common name is Chengdu Torrent Catfish.
