No full textTransandinomys Weksler, Percequillo & Voss 2006 The genus Transandinomys comprises two species, T. bolivaris (Allen 1901), and T. talamacae (Allen 1891). Both occur in tropical lowland and premontane trans-Andean rain forests from north-eastern Nicaragua throughout much of Costa Rica and Panama to Colombia, western Ecuador, and northern Venezuela (Musser et al. 1998; Weksler et al. 2006). All cytogenetic data available for the genus was presented on Table 10.

Drymoreomys Percequillo, Weksler & Costa 2011
No full textDrymoreomys Percequillo, Weksler & Costa 2011 Monotypic genus represented by D. albimaculatus (Percequillo, Weksler & Costa 2011), all known specimens were from the eastern slopes of the Serra do Mar, in the coastal Brazilian Atlantic Rainforest from Rio de Janeiro to Santa Catarina states (Percequillo et al. 2011; Delciellos et al. 2015). Karyotype: 2n = 62 and FN = 62. Autosomal complement: one small metacentric pair, and 29 acrocentric pairs large to small decreasing in size. Sex chromosomes: X, a large submetacentric; Y, a large submetacentric slightly smaller than the X (Suárez-Villota et al. 2013, pp. 68, Fig. 1; Delciellos et al. 2015). C-banding metaphases exhibited pericentromeric constitutive heterochromatic blocks on all autosomes and on the long arm of Y. G-banding was also performed. FISH with telomeric sequences revealed signals at the ends of all chromosomes, and additional telomeric sequences were found on the pericentromeric region of both X and Y chromosomes (Suárez-Villota et al. 2013).Published as part of 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, pp. 1-111 in Zootaxa 4876 (1) on page 13, DOI: 10.11646/zootaxa.4876.1.1, http://zenodo.org/record/442361
