Siluriformes (Catfishes) >
Pimelodidae (Long-whiskered catfishes)
Etymology: Pinirampus: Latin, pinna = fin + perhaps Old German, rampf = hook.
More on authors: Spix & Agassiz.
Issue
We have retained the younger name P. pirinampu (Spix & Agassiz) for purposes of stability, there has been virtually no use of P. barbancho since its original description, thus we treat it as a Nomen oblitum.
