The Stegophilinae are a subfamily of catfishes (order Siluriformes) of the family Trichomycteridae. It includes 12 genera: Acanthopoma, Apomatoceros, Haemomaster, Henonemus, Homodiaetus, Megalocentor, Ochmacanthus, Parastegophilus, Pareiodon, Pseudostegophilus, Schultzichthys, and Stegophilus.[1] A monophyletic group within the Stegophilinae is supported by two characteristics of the lateral line, including Acanthopoma, Henonemus, Megalocentor, Pareiodon, Parastegophilus, and Pseudostegophilus. Acanthopoma and Henonemus have a sister group relationship.[2]

The Stegophilinae are widely distributed in the main South American river basins, including the Amazon, Orinoco, São Francisco, Paraná-Paraguay, and those of southern Brazil.[3] Eight of the genera are distributed in Venezuela.[2]

Stegophilines are sometimes considered candirú, so are considered parasites or semiparasites, because of their peculiar habit of feeding on scales, mucus, or skin of other fishes.[2]
