Yunnanilus discoloris is a species of ray-finned fish, a stone loach, in the genus Yunnanilus. It is currently only in a single spring in the drainage basin of Lake Dianchi in Yunnan.
Yunnanilus discoloris is so named because of the sexual dimorphism this species shows. The specific name discoloris means differently coloured, it refers to the sexually dimorphic colour pattern. The males have a black longitudinal stripe on both flanks with a light blackish stripe of spots along its back while the female shows black spotting and blotching on both the back and the flanks.[3] It is a dwarf species which has a scaleless body and the origin of the dorsal fin is in halfway along the body.[4]
