Karyotype: 2n = 54 and FN = 66. Autosomal complement: seven metacentric and submetacentric pairs (three large and four small), and 19 acrocentric pairs (one large and the remaining medium to small). Sex chromosomes: X, a large subtelocentric; Y, was a medium acrocentric (Tavares et al. 2011, pp. 651, Fig. 4). The same diploid number was reported by Bonvicino et al. (2014, pp. 529, Fig. 10), but the authors reported a different fundamental number of 62 and 63, due to a presence of two small acrocentric pairs instead of two small submetacentrics, and due to a pericentric inversion involving one chromosome of a small autosome pair.
