Etymology: Apteronotus: Greek, apteros = without wings / (in this cases, fins) + Greek, noton = back (Ref. 45335); ferrarisi: Named for Carl J. Ferraris Jr. for his contirbutions to tropical freshwater fishes worldwide (Ref. 93867).
Issue
The report of Apteronotus sp. from the Tocuyo-Yaracuy region is presumably based on A. ferrarisi, which is the only member of the genus known to occur in those basins (Ref. 93867).
