Table 1 Localities/distribution of species of Neacomys with chromosomal data available in literature and karyotyped specimens in the present study. (2n) diploid number, (FN) autosomal fundamental number. Numbers in parentheses refer to localities shown in Fig. 1. Brazilian (BR) states are Amapá (AP), Mato Grosso (MT), and Pará (PA). Species analyzed with chromosome painting in the present study are bolded in the leftmost column
