Mystus (commonly known as Tengra) is a genus of small to medium-sized bagrid catfishes that occur in South and Southeast Asia.[1]

Mystus is poorly diagnosed. Macrones had previously been used by earlier authors, but this generic name was preoccupied in Coleoptera.[2] Phylogenetic relationships within this genus are poorly understood, though it has been suggested that there are two major lineages.[3] It was confirmed in 2005 that this genus is paraphyletic.[3]

There are two fossil species assigned to this genus both from the early Tertiary of the Sanshui Basin in Guangdong, China:


There are currently 45 extant species in this genus:[4][5][6][7]
