|Scientific Name||Mystus cavasius (Hamilton, 1822)|
|Common Name||Gangetic Mystus|
|Type Locality||Gangetic provinces.|
|Synonym(s)||Bagrus cavasius, Hypselobagrus nigriceps, Macrones cavasius, Macrones nigriceps, Mystus mukherjii, Pimelodus cavasius|

|Etymology||The generic name is probably derived from the Latin mystax, meaning moustache, in reference to the long barbels. It was first used by Scopoli in 1777 making it a very old genus that has included many catfishes from throughout the world at one time or another. The specific epithet comes from the local name of the fish (kavasi).|
|Size||400mm or 15.7" SL. Find near, nearer or same sized spp.|
|Identification||Fishes of the genus Mystus Scopoli are small to medium-sized bagrid catfishes occurring in South Asia. Roberts (1994) recognized Mystus to have an elongate cranial fontanel reaching up to the base of the occipital process, long maxillary barbel, very long adipose fin, 11–30 gill rakers on the first gill arch and 37–46 total vertebrae, about equally divided between abdominal and caudal regions. He included only eight species under the genus. Mo (1991) characterized the genus to have a thin needle-like first infraorbital, twisted and thickened metapterygoid loosely attached to the quadrate by means of ligament or a small extent of cartilage. Jayaram & Sanyal (2003) and Ferraris (2007) respectively listed 44 and 33 species of Mystus as valid.
Maxillary barbels, in adults, extend posteriorly beyond the caudal fin base, but in young specimen, do not extend beyond the anal fin. Color is grayish with a more or less well-defined midlateral longitudinal stripe. A dark spot emphasized by a white or pale area along its ventral margin located just anterior to the first dorsal spine.
|Sexing||Males have an elongate genital papilla in front of the anal fin.|
|Distribution||Lowland rivers in most major basins of the Indian subcontinent (Pakistan, Nepal, India, Sri Lanka and Myanmar), including but not limited to the Indus, Brahmaputra-Ganges, Krishna, Cauvery, Irrawaddy, Salween and Tenasserim. Reports of this species from the Chao Phraya and Mekong basins, Malaysia, and Indonesia are based on misidentifications of M. albolineatus or M. singaringan. Occurs in Thailand, but only in the Salween basin.
