abstract (from publication):
During 2015, we collected several specimens of a cichlid tentatively assigned to Geophagus in Yacyretá reservoir in the Paraná river basin (Argentina). By means of morphological and molecular evidence, we identified these specimens as Geophagus sveni, a species known from middle portion of the Tocantins River. Here we report the presence of the genus Geophagus (sensu stricto) in Argentina for the first time.
