After the publication of our article, we detected some inconsistencies in figures and figure captions. The nominal species Astyanax altiparanae was recently recognized as a new junior synonym of Astyanax lacustris Lütken, 1875. Thus, we corrected this issue in all figures. Captions of figure 3, 5 and 6 were also incorrect. Corrected figures and captions are as follows:

Figure 1.

Karyotypes of parental individuals analyzed: A. lacustris (3m+6sm+7st+9a), H. anisitsi (5m+1sm+10st+9a), A. fasciatus (5m+6sm+6st+7a) and A. schubarti (5m+5sm+5st+3a). Scale bar: 5µm.

Figure 2.

Karyotypes of hybrid products of the genus Astyanax: A. lacustris × H. anisitsi (8m+7sm+17st+18a), A. lacustris × A. fasciatus (8m+7sm+17st+18a) and A. lacustris × A. schubarti (8m+11sm+12st+12a), respectively. Scale bar: 5µm.

Figure 3.

Heterochromatic markers obtained by C-banding on metaphase plates of A. lacustris (a, d, g), A. fasciatus (b), A. schubarti (e), H. anisitsi (h) and hybrids A. lacustris × A. fasciatus (c), A. lacustris x A. schubarti (f) and A. lacustris × H. anisitsi (i) after C-banding. The arrows indicate heterochromatic blocks. The chromosomes number of A. lacustris and H. anisitsi hybrid is 2N = 51, the metaphase plate of A. lacustris and H. anisitsi hybrid (i) contains a heterochromatic chromosome (arrowhead). Scale bar: 5µm.

Figure 4.

FISH with probes 5S (green) and 18S (red). The results are labeled as: A. lacustris (a, d, g), A. schubarti (b), hybrid A. lacustris × A. schubarti (c), A. fasciatus (e), hybrid A. lacustris × A. fasciatus (f), H. anisitsi (h), and hybrid A. lacustris × H. anisitsi (i). The arrows indicate chromosomes inherited from A. lacustris, and the arrowheads indicate chromosomes inherited from the other respective parents. Scale bar: 5µm.
