Oligoryzomys destructor (Tschudi, 1844)

Moreira, Camila Do Nascimento, Ventura, Karen, Percequillo, Alexandre Reis & Yonenaga-Yassuda, Yatiyo, 2020, A review on the cytogenetics of the tribe Oryzomyini (Rodentia: Cricetidae: Sigmodontinae), with the description of new karyotypes, Zootaxa 4876 (1), pp. 1-111 : 61

Oligoryzomys destructor

Karyotype: 2n = 60 and FN = 76. Autosomal complement: nine metacentric and submetacentric pairs (two large and seven medium to small), and 20 acrocentric pairs (one large and the remaining small). Sex chromosomes: X, a large submetacentric; Y, a medium metacentric ( Gardner & Patton 1976, pp. 8, Fig. 3D ). This karyotype was referred as belonging to O. destructor by Weksler & Bonvicino (2015b). However, according to Hurtado & D’Elía (2019b), the authors taken these values arbitrary from Gardner & Patton (1976), whom described at least three karyotypes for specimens from localities in the current known distribution of O. destructor . Consequently, such specimens should be revised in order to confirm the karyotype of this species ( Hurtado & D’Elía 2019b).
