"resumo" => "The assemblage of species which have wide distribution and are related morphologically and phylogenetically is a complex of species. Species with old description and without recent taxonomic revision are candidates to be a complex of species. In 1840, the French zoologist Achille Valenciennes described the species Platystoma platyrhynchos, posteriorly, in 1862, Bleeker describe the monotypic genus Hemisorubim, designed Platystoma platyrhynchos as type species. Since then, more than 160 years have passed and Hemisorubim has not been taxonomically revised, and it has a wide distribution in the Neotropical region. In the present study, we used the species delimitation approach (ABGD, ASAP, bPTP, GMYC, mPTP) based on molecular data (Cytochrome oxidase subunit I) to investigate the number of species and the boundaries they comprise. The molecular results are represented by 42 sequences and 591 base pairs with a maximum intraspecific genetic distance of 5.13%. The species delimitation methods differentiate seven well-supported lineages corresponding to the Araguaia, Itaperucu, Marowijne, Madeira, Paraguay-Paraná, Upper Amazon, and Tapajós and Orinoco basins. These results provide a basis for future studies of systematic and evolution, as well as for the description of new species in the major Neotropical basins."
