Bassaricyon beddardi Pocock, 1921 Bassaricyon medius siccatus Thomas, 1927 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.

[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 closest relative of the eastern lowland olingo is the western lowland species, B. medius, from which it diverged about 1.3 million years ago.
