Pimelodus maculatus View in CoL . The diploid number of this species was also 56 chromosomes (24 m + 20 sm + 6 st + 6 a) ( Fig. 1c View Fig ). The AgNORs were located in the terminal region of the long arm of a pair of subtelocentric chromosomes 23 ( Fig. 1c View Fig , box). C-banding revealed the existence of pale heterochromatin in the region of the telomeres of some chromosomes, with more conspicuous heterochromatin being found in the telomeric region of the short arm (pair 6) and long arm (pairs 17, 22, 23 and 24), in both telomeres (pair 8) and the pericentromeric region of the short arm (pairs 1 and 25) and in long arm in pair 21 ( Fig. 2c View Fig ). The 18S rDNA and 5S rDNA showed syntenic sites in the terminal region of the long arm of a pair of subtelocentric chromosomes (23), which corresponds to the AgNORs ( Fig. 3c View Fig ).
