Mystus nigriceps, the two-spot catfish, is a species of catfish of the family Bagridae. The species was available in aquarium circles without a scientific name until a connection was made to a description of Mystus micracanthus by the ichthyologist Bleeker, in 1846. The artist's impression at that time showed a catfish without any obvious markings, although another researcher in the early 1940s described it with two body spots. M. micracanthus is a junior synonym of M. nigriceps. In the wild it is found in Cambodia, Indonesia, Laos, Malaysia, Singapore and Thailand.
