Amphiliids are small (the largest species reach to about 200 mm SL) benthic riverine catfishes with a wide range of body form from soft-bodied to slender, firm-bodied and highly streamlined forms, some with bony plates along the body.

Doumeine amphiliids are mostly slender and streamlined, well adapted to living in fast flowing currents. Their axial skeleton is progressively modified in the different species forming, in most genera, linear series of bony ridges or ‘plates’ along the body.
