Ein Schwanzwurzelfleck ist bei beiden Formen vorhanden und war nie ein Merkmal zur Differenzierung der nun als valide Arten betrachteten Taxa. Unrelated obligate phytophages have also converged on a similar body shape that is distinct from sympatric congeneric herbivores. Although significant methodological advances have occurred for molecular evaluation, they are still modestly applied to the study of neotropical fish genera, in which Hypostomus is included. This standard is not always adapted, such as in French Guiana subjected to high natural background Hg levels and intensive illegal gold mining.
