Thollon's red colobus (Piliocolobus tholloni), also known as the Tshuapa red colobus,[3] is a species of red colobus monkey from the Democratic Republic of the Congo and lower Republic of the Congo.

It is found south of Congo River and west of Lomami River.

[1] It had once been considered a subspecies of the P. badius.

It was recognised as a distinct species by Dandelot in 1974, and this was followed by Groves in 2001, while others have suggested it should be considered a subspecies of P.
