A new estuarine bagrid catfish has been described from the Malay Peninsula.

Heok Hee Ng, a prolific and well-known catfish systematist working at the Fish Division of the University of Michigan's Museum of Zoology, named the new species of catfish as Mystus armiger in a paper in the latest issue of the journal Copeia.

Ng found Mystus armiger in the estuarine waters of the Kelantan River in the northeastern tip of the Malay Peninsula.

He claims that the new species looks like Mystus wolffii, as both species share a uniform colour pattern without dark markings, have long maxillary barbels which reach the base of the caudal fin, and have anal and adipose fins of roughtly equal length.

Mystus armiger, however, has a broader snout than wolffii, fewer large serrations on the stout pectoral spines and a smaller eye.
