Hylaeamys Weksler, Percequillo & Voss 2006
The genus Hylaeamys comprises seven species, namely H. acritus (Emmons & Patton 2005), H. megacephalus (Fischer 1814), H. oniscus (Thomas 1904), H. perenensis (Allen 1901), H. seuanezi (Weksler, Geise & Cerqueira 1999), H. tatei (Musser, Carleton, Gardner & Brothers 1998), and H. yunganus (Thomas 1902) . These species were distributed in moist forests of cis-Andean tropical and subtropical lowlands and foothills from Venezuela and the Guianas southward throughout Amazonia and the Atlantic rainforest to Paraguay and northern Argentina (Weksler et al. 2006; Brennand et al. 2013; Percequillo 2015d). All cytogenetic data available for the genus was presented on Table 5, and the distribution of diploid and fundamental number of karyotyped specimens were presented on Fig. 6.
