Amphilius is a genus of catfishes of the family Amphiliidae. Amphilius catfish have fairly lengthened bodies, with short, depressed, and broad heads. They have three pairs of fringed barbels. The eyes, small and located dorsally, are very distant from each other, and are without a free edge. The caudal fin is forked or emarginated. Unlike species of Paramphilius, the snout is greater than half of the snout length, the adipose fin is not confluent with the caudal fin in adult specimens, and the anal fin has seven or fewer branched rays.
