abstract (from publication):
The area of La Plata River and Buenos Aires Delta in Argentina has records of at least three species of freshwater silversides (Odontesthes bonariensis, O. perugiae and O. retropinnis). Odontesthes humensis was originally described in 1953 by the Spanish ichthyologist Fernando de Buen from the Río Negro Basin in Uruguay. It was listed on several occasions as borderline species in Argentina but its presence could never be confirmed. The aim of this study is to confirm that Odontesthes humensis is present in argentine waters. The morphological characters of the specimens discussed in this work allow a clear taxonomic assignment.
