Thollon’s Red Colobus Characteristics

The Thollon’s red colobus[1] (Piliocolobus tholloni), also called the Tshuapa red colobus, is native to the Democratic Republic of the Congo and the Lower Republic of the Congo.

  • It is located west of the Lomami River and south of the Congo River. It was once thought to be a subspecies of Piliocolobus badius.
  • It was recognized as a separate species by Dandelot in 1974, followed by Groves in 2001. Others have suggested it be considered a subspecies of Piliocolobus rufomitratus.
  • Thollon’s red colobus reaches a head-to-body length of 450-670 mm (18-26 in) with a tail of 520-800 mm (20-31 in) and weighs 5-11 kg (11-24 lb).
  • It has a red or brown head and limbs and a black, slate gray, or dark brown upper part. It does not have long tufts of hair or fringes on its tail.
  • Compared to other Colobus monkeys, the nostrils are V-shaped, the fingers are long, and the big toe is short.
