Hoplerythrinus unitaeniatus is a species of economic importance, widely distributed in the Brazilian territory. Many studies have reported the karyotypic variation that occurs in the species, which forms two groups according to the diploid number, one with 2n = 52 and the other with 2n = 48. In this work, three populations of H. unitaeniatus from different hydrographic basins were cytogenetically analyzed. The diploid number found was 2n = 48 for all populations, however, differences in karyotypic formula and fundamental number and heterochromatin distribution were also observed. Ag-NORs were multiple, GC-rich and when applied FISH with 18S rDNA bright signals in six chromosomes were observed. Data from this study confirm the occurrence of interpopulation variability in H. unitaeniatus. The basal number and the possible divergence among the different cytotypes analyzed for this species to date, as well as the forward the proposal of biogeographic and tectonic history for the continental margin are discussed.
