Anisitsia Eigenmann [C. H.] & Kennedy [C. H.] in Eigenmann 1903:144 Fem. Anodus notatus Jardine in Schomburgk 1841. Type by original designation (also monotypic). •Synonym of Hemiodus Müller 1842 -- (Roberts 1974:432 [ref. 6872], Géry 1977:198 [ref. 1597], Langeani 1998:157 [ref. 23841], Langeani in Reis et al. 2003:97 [ref. 27061]).
