Karyotype after C band. Ancistrus sp. “Currupira” has 2n=44 chromosomes and showed heterochromatin blocks mainly at centromeric regions and pair 13 (A), Ancistrus sp. “Pari” has 2n=42 chromosomes with heterochromatin blocks along centromeric regions and a big block in pair 15 (B) and Ancistrus sp. “Sangradouro” has 2n=42 chromosomes, a karyotype similar to Ancistrus sp. “Pari” but the big heterochromatin block is in pair 6 (C). Bar = 10 µm.
