Karyotype: 2n = 60 and FN = 72. Autosomal complement: seven metacentric and submetacentric pairs medium to small decreasing in size, and 22 acrocentric pairs (three large and the remaining small). Sex chromosomes: X, a medium acrocentric; Y, a small acrocentric ( Kiblisky 1969, pp. 1339, Fig. 3 View FIGURE 3 ). Another karyotype with a different diploid and fundamental number was reported by Gardner & Patton (1976), 2n = 62 and FN = 74 or 76 (fundamental number comprises autosomal and sex chromosomes). Chromosome complement: five metacentric pairs (one large and four small), three subtelocentric pairs large to small decreasing in size, and 23 acrocentric pairs (one very large and the remaining small), the sex chromosome of this karyotype was unknown as only a female was examined. Baker et al. (1983) reported a diploid number of 60 and 64 for O. delicatus , and presented the G-banding for these karyotypes. These variation in diploid and fundamental number of O. delicatus occurs in different localities of Suriname and Venezuela ( Table 9). This karyotype was originally attributed to O. longicaudatus , variant 3, by Gardner & Patton (1976), but Weksler & Bonvicino (2015b) assigned it to O. delicatus .
