The dark spiny tree-rat (Echimys saturnus) is a species of
rodent in the family
Echimyidae.[2] It is a rarely encountered and nocturnal species, found in eastern
Ecuador and central
Peru.[3][4]
Compared to Echimys chrysurus, the main diagnostic
character state of this Echimys species is the mostly black dorsal part of the head and body. In addition, E. saturnus can be distinguished from Echimys vieirai by possessing a venter spotted with white while it is uniformly grayish brown in the latter species.[5]
