The maned wolf, <I>Chrysocyon brachyurus</I>, is a vulnerable species of the Canidae family inhabiting tall grass savannas and grasslands of central South America. Few ecological and genetical studies have been conducted on this canid. From a cytogenetic viewpoint, the karyotype of <I>C. brachyurus</I> is closely similar to that of the domestic dog (<I>Canis familiaris</I>) although both species differ each other in the diploid number and fundamental number (2n=76 and FN=78; 2n=78 and FN=80, respectively). In the present study, different chromosome banding methods (G, C, Ag-NOR and base-specific fluorochrome staining) were used for a better chromosome characterization of <I>C. brachyurus</I>. Additionally, some aspects of the chromosome evolution of Canidae were also discussed.
