Hemimyzon taitungensis (common name: Taitung river loach, in Chinese èºæ±éÂÂç¬岩é°Â, å°æ±éÂÂå¸é°Â, or ç³貼ä»Â) is a species of ray-finned fish in the family Balitoridae that is endemic to Taiwan. It is a small (length ) freshwater fish currently known only from running waters of the Central Mountain Range of Taiwan at high and middle elevations. In contrast to H. formosanus, it appears to be a well-defined species with no signs of strong genetic structuring suggestive of cryptic species.
