The Stegophilinae, the parasitic catfishes, is a subfamily of freshwater ray-finned fishes belonging to the family Trichomycteridae, the pencil and parasitic catfishes. 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.[4]
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.[5] Eight of the genera are distributed in Venezuela.[4]
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.[4]
