Valenciennes in Cuvier & Valenciennes, 1840
A. phrygiatus and A. rugispinis were both originally described by Achille Valenciennes in 1840 as Arius species, where they have been traditionally placed. They have also been classified in the genus Notarius. Since then, it has been recognized that these two species form a natural, monophyletic grouping and were suggested to represent a new, undescribed genus. The genus Amphiarius was finally erected for these two species in 2007.
- Amphiarius phrygiatus (Valenciennes, 1840) (Kukwari sea catfish)
- Amphiarius rugispinis (Valenciennes, 1840) (Softhead sea catfish)
Amphiarius are distinguished from all other ariids by the presence of accessory tooth plates that are small to moderate, roughly round, and laterally located.
Like other ariid catfishes, Amphiarius species are mouthbrooders.
Relationship to humans
Both species are caught and marketed for human consumption.
