Cytogenetical studies on Hoplias malabaricus, intensive in the last few years, have determined that it does not represent only 1 species, as it is classified, but a complex of species with 7 cytotypes , some of them living in a sympatric condition with no hybrids. In this study, for the first time, 3 cytotypes were found in sympatry and sintopy in the Upper Paraná River floodplain. Cyytotaxonomy and geographical aspects are discussed.
