Material examined. Holotype of Platytropius yunnanensis: YU 8040066, 220 mm SL, Yunnan: Longyang District (=Baoshan County): Daojie Township, main stream of the Nu-jiang; Paratype of Platytropius yunnanensis: YU 8040127, 232 mm SL, collected with the holotype of Platytropius yunnanensis . Holotype of Clupisoma nujiangense: KIZ 200310118, 200 mm SL, Yunnan: Longling County: Mengnuo Township: Sanjiangkou, main stream of the Nu-jiang; Paratypes of Platytropius yunnanensis: KIZ 200310117, KIZ 200310119–120, KIZ 200310125–127, 6 ex., 203.7–241.7 mm SL, collected with the holotype of Clupisoma nujiangense .
Diagnosis. Morphometric and meristic data are shown in Tables 1 and 2. Clupisoma yunnanense is distinguished from its congeners occurring in China by the following combination of characters: palatal tooth patch consists of slender oblique bands that extends nearly to midline, clearly interrupted and not connected to each other (vs. crescent-shaped bands that extend to midline and almost connect to each other); lateral mental barbels short, not extending to ventroposterior margin of operculum (vs. extending to pectoral-fin origin or to anal-fin origin); pelvic fin short, only extending to anal-fin origin (vs. extending beyond anal-fin origin).
Distribution. The lower of Nu-jiang, belonging to the upper Salween River basin (Fig. 2).
