Bullockia Cambeva Eremophilus Hatcheria Ituglanis Rhizosomichthys Scleronema Silvinichthys Trichomycterus The Trichomycterinae are a subfamily of catfishes (order Siluriformes) of the family Trichomycteridae.

It includes six genera, Bullockia, Hatcheria, Rhizosomichthys, and Eremophilus, all monotypic, Silvinichthys with seven species, and Trichomycterus, with over 170 species.

The former five genera are diagnosed by putatively apomorphic characters, whereas Trichomycterus is defined by the lack of those specializations and is likely not monophyletic.

[1] Species of Trichomycterinae dwell in headwaters and small, cold clear water streams running over stony beds.

Due to the patchy distribution of their habitats, trichomycterines generally have restricted geographic distributions, thus display a high level of endemism.
