abstract (from publication):
The history of red-eyed Moenkhausia in Argentina dates back to 1937 when Meinken mentioned M. sanctaefilomenae for the first time based on specimens received from Corrientes. Meinken’s lot still exists in the ichthyological collection in Berlin and based on this material and preserved specimens from other collection we can confirm that from the species group of the red-eyed Moenkhausia so far only M. australis and M. forestii have been collected in Argentina, while the records of M. sanctaefilomenae must be considered erroneous.
