Mystus wolffii • Bagridae • Cat-eLog

Cat-eLog Data Sheet
Scientific Name	**Mystus wolffii** (Bleeker, 1851)
Common Name(s)	None
Type Locality	Bandjarmasin, Borneo, Indonesia.
Synonym(s)	Bagrus wolffii, Hypselobagrus wolffii, Macrones wolffii, Mystus armiger
Pronunciation	miss tuss
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.
Species Information
Size	200mm (7.9") 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. Nasal barbels longer than head; maxillary barbels reaching to caudal fin;
Sexing	Males have an elongate genital papilla in front of the anal fin.
