Description: Sineuchiloglanis chishuiensis sp. nov. can be distinguished from its congeners by the combination of the following characters: eye enlarged, with diameter 6.8–9.1% of head length (HL); interorbital width 24.1–24.8% of HL; maxillary barbel length 67.1–84.4% of HL; caudal-peduncle depth 27.1–40.3% of caudal-peduncle length; dorsal-fin rays i, 51/2; anal-fin rays i, 41/2; caudal-fin rays i, 7+8, i; gill opening extending to the base of second to third pectoral-fin elements; tip of nasal barbel not reaching anterior orbital margin; pelvic-fin tip reaching or extending beyond anus; and the abdomen slightly convex in profile. Colouration: In fresh specimens, body green-yellow on dorsal surface. On venter, from snout to the pelvic-fin insertion milky white, after pelvic-fin green-yellow. Around the anus pale yellow. Pectoral-fin and pelvic-fin with pale yellow distal margins, lateral green-yellow and medial pale yellow. Dorsal-fin, adipose-fin, and anal-fin green-yellow with pale yellow distal margins. Caudal fin green-yellow with a small pale yellow patch and pale yellow distal margin. In alcohol-fixed specimens, body grey, ventral surface, and margins of fins milky white (Lv. et al 2026). Habitat: Inhabits rapids and riffles, with primarily rocky substrates (Lv. et al 2026). Aquarium Care: This species is sensitive to temperature and oxygen levels, so the water should be on the cool side and well-oxygenated, preferably with a moderate to strong current. Additional tank decor can be in the form of large driftwood and/or rocks. Etymology: The specific name chishuiensis: Derived from its type locality, Chishui River. Remarks: A new paper (2026) based on a revalidation of the Sineuchiloglanis genus.
