Eastern lowland olingo
The eastern lowland olingo (Bassaricyon alleni) is a species of olingo from South America, where it is known from the lowlands east of the Andes in Bolivia, Brazil, Colombia, Ecuador, Guyana, Peru and Venezuela.[1][3] It is the only olingo species found east of the Andes.[2] The Latin species name honors Joel Asaph Allen, the American zoologist who first described the genus Bassaricyon.[4]

Description
    
The eastern lowland olingo is smaller than the northern olingo, but larger than the recently described olinguito ("little olingo"), the most montane member of the genus.[2] It is larger than the western lowland olingo subspecies B. medius medius from west of the Andes, but about the same size as the B. m. orinomus subspecies from eastern Panama.[2] The pelage is slightly darker than the western species.[2]
It has a head-body length of 30 to 45 centimetres (12 to 18 in), with a tail length of 40 to 53 centimetres (16 to 21 in).[2] It weighs 1.1 to 1.5 kilograms (2.4 to 3.3 lb).[2]
Taxonomy
    
The closest relative of the eastern lowland olingo is the western lowland species, B. medius, from which it diverged about 1.3 million years ago.[2]
