SPECIES Rhipidomys nitela

Author:Thomas, 1901.
Citation:Ann. Mag. Nat. Hist., ser. 7, 8: 148.
Common Name:Guianan Rhipidomys
Type Locality:Guyana, Rupununi Dist., Kanuku Mountains, Kwaimatta, 240 ft (73 m).
Distribution:Amazonian lowlands in S Venezuela, Guianas, and NC Brazil. The reports of the species in Bolivia (Anderson, 1997) and Colombia (Tribe, 1996) cannot be confirmed, and the species appears to be confined to Amazonia east of the Rios Negro-Madeira as so far documented (see Voss et al., 2001).
Status:IUCN Lower Risk (lc).
Comments:R. leucodactylus section sensu Tribe (1996). Previously listed either as a race of R. venezuelae (Gyldenstolpe, 1932) or R. mastacalis (Cabrera, 1961), but distinct from true venezuelae in Venezuela (see Handley, 1976, who used the species name mastacalis) and from the mastacalis complex in EC Brazil (Tribe, 1996). Morphometric and chromosomal variation cautions that populations arranged as nitela represent a composite of two species (Tribe, 1996; Volobouev and Catzeflis, 2000); Andrades-Miranda et al. (2002a) considered the 2n = 48 and FN = 68 karyotype to represent R. nitela proper.
