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 : 47

Nesoryzomys narboroughi

Karyotype: 2n = 32 and FN = 50. Autosomal complement: eight metacentric and submetacentric pairs large to medium decreasing in size, two subtelocentric pairs (one large and one medium), and five acrocentric pairs (one medium and four small). Sex chromosomes: X, a medium acrocentric; Y, a small acrocentric ( Gardner & Patton 1976, pp. 10, Fig. 4C ).
