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 .
