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 Indoneisan name of the fish.

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.

Uniform dark grey body; the adipose fin much longer than the anal fin and contiguous with the dorsal fin; very long barbels, with the maxillary barbels reaching to or beyond the the caudal-fin base. Cranial fontanel extends to base of occipital process.
Sexing Males have an elongate genital papilla in front of the anal fin.
General Remarks Usually associated with slow-flowing, turbid waters and soft bottom. Feeds on insect larvae, zooplankton and small fishes. In the Mekong River drainage, it moves into the flooded riparian forests during periods of high water and returns to rivers during November and December.
