Hemimyzon taitungensis

Hemimyzon taitungensis (common name: Taitung river loach,[2] in Chinese 臺東間爬岩鰍, 台東間吸鰍, or 石貼仔[2][3]) is a species of ray-finned fish in the family Balitoridae that is endemic to Taiwan.[2][3][4] It is a small (length 12 cm (4.7 in)) freshwater fish currently known only from running waters of the Central Mountain Range of Taiwan at high and middle elevations.[3] In contrast to H. formosanus, it appears to be a well-defined species with no signs of strong genetic structuring suggestive of cryptic species.[5]
