abstract (from publication):
Brachyhypopomus bombilla, B. draco and B. gauderio are recorded for the first time in freshwaters of Argentina. These species were collected in the Río Paraná basin at the Iberá Wetlands and Pre-Delta National Park. Brachyhypopomus bombilla, B. draco and B. gauderio can be sympatric and syntopic in Pre-Delta National Park, whereas B. bombilla and B. gauderio occupy the same environments in the Iberá Wetlands. Some records of B. brevirostris for Argentina are misidentifications of B. gauderio, whereas others could correspond to one of these three species.
