Neacomys Thomas 1900

The genus Neacomys comprises 11 species, N. dubosti ( Voss, Lunde & Simmons 2001) , N. guianae (Thomas 1905) , N. macedoruizi ( Sánchez-Vendizú, Pacheco & Vivas-Ruiz 2018) , N. minutus ( Patton, Silva & Malcolm 2000) , N. musseri ( Patton, Silva & Malcolm 2000) , N. paracou ( Voss, Lunde & Simmons 2001) , N. pictus (Goldman 1912) , N. rosalindae ( Sánchez-Vendizú, Pacheco & Vivas-Ruiz 2018) , N. spinosus (Thomas 1882) (that includes N. spinosus , N. amoenus amoenus (Thomas 1903) , and N. a. carceleni (Hershkovitz 1940)), N. tenuipes (Thomas 1900) , and N. vargasllosai ( Hurtado & Pacheco 2017) . These species occur throughout the Amazon Basin in Brazil, Colombia, Peru, Ecuador, Bolivia, Venezuela, Guyana, Suriname, and French Guiana, and west of the Andes from easternmost Panama to Ecuador and Venezuela. The genus has never been broadly revised and the most recent revisionary efforts were elaborated by Patton et al. (2000) and Voss et al. (2001; see also Prado & Percequillo 2013; Weksler & Bonvicino 2015a; Hurtado & Pacheco 2017; Sánchez-Vendizú et al. 2018) for western and eastern amazon localities, respectively. All cytogenetic data available for the genus was presented on Table 6, and the distribution of diploid and fundamental number of karyotyped specimens were presented on Fig. 7 .
