Pimelodus maculatus Lacepede 1803
, 2018 Pimelodus maculatus. The diploid number of this species was also 56 chromosomes (24 m + 20 sm + 6 st + 6 a) (Fig. 1c). The AgNORs were located in the terminal region of the long arm of a pair of subtelocentric chromosomes 23 (Fig. 1c, box). C-banding revealed the existence of pale heterochromatin in the region of the telomeres of some chromosomes, with
