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 : 60

Oligoryzomys brendae

Karyotype: 2n = 58 and FN = 74. Autosomal complement: nine metacentric and submetacentric pairs (two large and remaining small), and 19 acrocentric pairs (one large and the remaining small). Sex chromosomes: X, a medium submetacentric; Y, a small acrocentric. G-banding was also performed ( Espinosa & Reig 1991, pp. 311, Fig. 3A ; Teta et al. 2013).
