Stegophilinae is a subfamily of catfishes (order Siluriformes) of the family Trichomycteridae.
It includes twelve genera, Acanthopoma, Apomatoceros, Haemomaster, Henonemus, Homodiaetus, Megalocentor, Ochmacanthus, Parastegophilus, Pareiodon, Pseudostegophilus, Schultzichthys, and Stegophilus.[1] A monophyletic group within 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 subfamily Stegophilinae is 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, and are considered parasites or semi-parasites, because of their peculiar habit of feeding on scales, mucus, or skin of other fishes.[2]
