Zygodontomys sp. 2

Karyotype: 2n = 82 and FN = 94. Autosomal complement: seven biarmed pairs (two large and five medium to small pairs), and 33 medium to small acrocentric pairs decreasing in size. Sex chromosomes: X, a large submetacentric; Y, a small submetacentric ( Bonvicino et al. 2003, pp. 124, Fig. 2A ; Bonvicino et al. 2009).

Unnamed generic taxon, currently named Handleyomys

These species its provisional position as a member alfaroi group because no new genus to encompass these taxa has yet been described, alfaroi (Allen 1891) , chapmani (Thomas 1898), melanotis (Thomas 1893) , rhabdops (Merriam 1901), rostratus (Merriam 1901), and saturatior (Merriam 1901) (Weksler 2015a).
