Oecomys Thomas 1906

The genus Oecomys comprises at least 18 recognized species, O. auyantepui (Tate 1939) , O. bicolor (Tomes 1860) , O. catherinae (Thomas 1909) , O. cleberi (Locks 1981) , O. concolor (Wagner 1845) , O. flavicans (Thomas 1894) , O. franciscorum ( Pardiñas, Teta, Salazar-Bravo, Myers & Galliari 2016) , O. mamorae (Thomas 1906) , O. paricola (Thomas 1904) , O. phaeotis (Thomas 1901) , O. rex (Thomas 1910) , O. roberti (Thomas 1904) , O. rutilus (Anthony 1921) , O. speciosus (Allen & Chapman 1893) , O. superans (Thomas 1911) , O. sydandersoni (Carleton, Emmons & Musser 2009) , O. tapajinus (Thomas 1909) , and O. trinitatis (Allen & Chapman 1893) . These species were broadly distributed in lowland forested areas from Costa Rica southward to southern Bolivia and north-eastern Argentina ( Musser & Carleton 2005; Carleton & Musser 2015; Pardiñas et al. 2016; Rocha et al. 2017; Suárez-Villota et al. 2017). All cytogenetic data available for the genus was presented on Table 8, and the distribution of diploid and fundamental number of karyotyped specimens were presented on Fig. 12 and Fig. 13 .
