description
The same karyotype was reported by Pereira & Geise (2007). The authors reported a different fundamental number of 66 due to the presence of one small metacentric pair instead of an acrocentric one. Furthermore, they reported a specimen with 2 n = 51, with one large acrocentric chromosome without homologous and one more pair of small acrocentric chromosomes. The basic diploid number of 2 n = 50 was also reported by Percequillo et al. (2008), who also reported a different fundamental number of 62 due to a presence of one small acrocentric pair instead of a metacentric one, these authors also found a fundamental number of 63 in one male and one female, due to a pericentric inversion involving one chromosome of a medium autosome pair. Another difference was related with the size of Y chromosome smaller on these samples. These variation in diploid and fundamental number of C. vivoi occurs sympatrically on specimens collected in Bahia and Minas Gerais, states of Brazil (Table 2, Fig. 2).
