Dent's mona monkey (Cercopithecus denti) is an Old World monkey in the family Cercopithecidae found in Central Africa. Debate on whether it constituted a separate species or subspecies continued between zoologists, and it was previously classified as a subspecies of other monkeys by some of them. It was re-classified as a separate species in 2001. It is classified as Least Concern in the IUCN Red List.
Dent's mona monkey is an Old World monkey in the family Cercopithecidae. The species was described by English zoologist Oldfield Thomas in 1907. Debate on whether it constituted a separate species or subspecies continued between zoologists. While many zoologists classified it as a separate species, it was classified as a subspecies of other monkeys by mona monkey, Wolf's mona monkey, and crested mona monkey by some of them across the years. Further research was required to examine the various species of mona monkeys in the forests between the Lualaba and Lomani rivers. It was re-classified as a separate species in 2001.

Very likely
About 70% of wildlife watchers report a Dent’s Monkey sighting in Semuliki National Park on a given day, based on 10 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 2nd most-seen of the 7 mammals we can rate there. Over three days the chance rises to over 90%, if each day is a fresh chance.
January
In that month about 80% of wildlife watchers report a Dent’s Monkey in Semuliki National Park on a given day, against about 30% in October, the lowest month. That is one of Semuliki National Park's driest months, with about 5 mm of rain against 140 mm in May. March, May, August–September and December have too few records to rate.
Between 8 and 11 am
Across all the parks we cover, that three-hour window holds the most Dent’s Monkey sightings with a recorded time, and about 9 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
Yes
Of the 2 parks where we can rate Dent’s Monkey sightings, Semuliki National Park has the highest daily chance: about 70%. Next come Nyungwe National Park (Rwanda, about 40%).
Same genus: Cercopithecus
The closest relatives of the Dent’s Monkey that you can see in Semuliki National Park (genus Cercopithecus, Guenons) are Red-tailed Monkey (about 70%) and De Brazza’s Monkey (about 70%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Dent’s Monkey is recorded against all the mammals logged in Semuliki National Park (10 verified sightings from 2019 to 2026), calibrated against known sighting rates. Figures are rounded to the nearest 10% because citizen-science data supports honest approximations, not decimals, and months with records from fewer than five people show "—". How it works.
