The methods of the traditional taxonomy will not be enough to satisfactorily describe the biodiversity on the planet before its extinction due to restrictions on the identification of species characterized by "taxonomic impediments". Alternatives such as integrative taxonomy that include molecular analyzes for species delimitation are proposed in order to enable the identification of biodiversity more quickly, including cryptic lineages. In this project we will address the taxonomy of the genus Eigenmannia. This genus is widely distributed in the neotropical region, occurring from Panama to northern Argentina. Currently, 20 species are recognized in the genus, and some studies indicate that the group may be more diverse than the one currently known. The lack of definition of valid species, especially those described in the 19th and early 20th centuries, maintains Eigenmannia with one of the most confusing taxonomies within the order. In addition to the taxonomic knowledge, the project also aims to investigate its phylogenetic relationships through a total evidence approach to solve questions about the delimitation of the genus as well as the phylogenetic relationships of its species.
