A review on the cytogenetics of the tribe Oryzomyini (Rodentia: Cricetidae: Sigmodontinae), with the description of new karyotypes Author Moreira, Camila Do Nascimento Author Ventura, Karen Author Percequillo, Alexandre Reis 0000-0001-9490-5457 cmoreirabio@gmail.com Author Yonenaga-Yassuda, Yatiyo text Zootaxa 2020 2020-11-06 4876 1 1 111 journal article 7983 10.11646/zootaxa.4876.1.1 4ee8b608-7c73-4980-9e86-3e3719e91c7f 1175-5326 4423612 190EC586-E14B-4AEF-A5EF-3DA401656159 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 ).
