  • First fossil record for the family Trichomycteridae (Teleostei: Siluriformes; Pliocene) inthe Monte Hermoso Formation, Argentina. Some fossil remains referable to the siluriform familyTrichomycteridae are described in this paper. These specimens exhibit a combination of characters that allow toinclude them within the subfamily Trichomycterinae. These elements consist on an opercular and interopercularof the same individual, collected in Lower-Middle Pliocene beds of the Monte Hermoso Formation, at the Farolade Monte Hermoso locality, Buenos Aires province, Argentina. This record constitutes the first fossil remainsreported for the family, and one of the few paleoichthyological records for the Monte Hermoso Formation.
