The Copionodontinae are a subfamily of catfishes (order Siluriformes) of the family Trichomycteridae. It includes two genera, Copionodon and Glaphyropoma.[3]
Copionodontines are remarkably primitive in body form, and lack many of the synapomorphies previously used to diagnose the family Trichomycteridae. Little doubt exists that the Copionodontinae form a monophyletic group, diagnosed by several unambiguous synapomorphies, including a unique dentition composed of spatulate teeth not seen anywhere else in the Trichomycteridae. A few characters also support the genera Copionodon and Glaphyropoma as monophyletic subunits.[3]
