After the publication of this work [1] the following errors were brought to the authors’ attention: Figure 1 contained a misspelling of the species name Leporinus reinhardti, and Figures 2 and 3 contained mistakes that occurred during the editing process. The correct figures are given below.

thumbnailFigure 1. Giemsa-stained female karyotypes of Leporinus reinhardti (2n = 54) and Triportheus auritus (2n = 52), both with a ZZ/ZW sex chromosome system. The chromosomes of both species were arranged in descending order of size and the sex chromosomes were highlighted in boxes for the sake of clarity. Bar = 5 μm.

thumbnailFigure 2. Mitotic metaphase chromosomes of Leporinus reinhardti female, with a ZZ/ZW sex chromosome system hybridized with different repeated DNAs, including mono-, di- and trinucleotide microsatellites and an 18S rDNA gene as probes. Letters mark the W chromosomes. Bar = 5 μm.

thumbnailFigure 3. W chromosomes of Leporinus reinhardti (L) and Triporteus auritus (T) after C-banding and FISH with various repetitive DNA sequences. Note the huge accumulation of several classes of microsatellites in L. reinhardti and the lesser amount of this accumulation in T. auritus.

We regret any inconvenience that this inaccuracy may have caused.
