Etymology: Eigenmannia: From Eigenmann, 1910, researcher of faunistic studies (Ref. 45335); dutrai: Named for Guilherme M. Dutra, for his contribution to the field of ichthyology, in particular to the taxonomy of Eigenmannia.
Eponymy: Professor Dr Carl Henry Eigenmann (1863–1927) was a German-born American ichthyologist.
