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 : 46

Nephelomys auriventer

Karyotype: 2n = 70 and FN = 84. Autosomal complement: eight medium to small metacentric and submetacentric pairs, and 26 acrocentric pairs large to small decreasing in size. However, if the largest autosomal pair was considered as a subtelocentric, the FN would be 86. Sex chromosomes: X, a medium metacentric; Y, a small submetacentric ( Gardner & Patton 1976, pp. 4, Fig. 1D ).
