Although Hyphessobrycon is usually treated as a valid genus (Durbin in Eigenmann 1908, Eigenmann 1917, 1918, 1927, Gery 1977, Garcia-Alzate et al 2008a), it remains poorly defined and is polyphyletic. No modern hypothesis of phylogenetic relationships exists for all species of the genus, and the characters traditionally used to define species have not been analyzed in a phylogenetic perspective, often leading to misinterpretation of those characters.
Molecular methods also do not exclude false negative.Phylogenetic analysis based on mitochondrial gene sequences placed Haemoproteus as polyphyletic group in the same clade as Plasmodium [37].
