The genus Gymnotus (Gymnotiformes) is a group of fishes with karyotypic plasticity, demonstrated by cytogenetic studies using whole chromosome probes of G. carapo (
GCA
, 2n = 42) that were obtained by flow-sorting from fibroblast cultures. In the present work we undertook comparative mapping of the karyotype of G. capanema (GCP, 2n = 34) with
GCA
, 2n = 42 painting probes. The results demonstrate that the karyotype of G. capanema is extensively rearranged when compared to G. carapo. From the 12 chromosome pairs of G. carapo that can be individually differentiated (GCA1-3, 6, 7, 9, 14, 16 and 18-21), only 4 pairs (GCA6, 7, 19, and 20) maintained conserved synteny in G. capanema. From these 4, GCA6 and GCA20 correspond to individual chromosomes (GCP8 and GCP15), while the other 2 share homology with parts of GCP1 and
GCP2
, respectively. The remaining GCP chromosomes showed more complex hybridization patterns with homologies to other
GCA
pairs. These results demonstrate that the level of reorganization in the genome of G. capanema is much greater than in
GCA
, 2n = 42 and in karyomorph
GCA
, 2n = 40 which was previously analyzed by chromosome painting.
