Hydrocynus lucius Cuvier, 1816 | in L sub Boulengerella lucius | Vari (1995)

Vari (1995): “ Boulengerella species have been cited from the Río de La Plata basin commencing with Holmberg

[1893]… It appears that Holmberg's record represents a misidentification, perhaps of an Acestrorhynchus species. ”
