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 Cerradomys goytaca 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.
