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 : 76

Oligoryzomys sp.

Karyotype: 2n = 68 and FN = 74 or 76. Chromosome complement: one large subtelocentric pair, four metacentric and submetacentric pairs of small sized, and 29 acrocentric pairs large to small decreasing in size. The sex chromosome was unknown as only a female was examined ( Gardner & Patton 1976, pp. 8, Fig. 3A ).
