The Lucifer titi monkey (Cheracebus lucifer) is a species of titi, a type of New World monkey, from South America. It is found in Brazil, Colombia, Ecuador, and Peru. It was described as Callicebus lucifer in 1914. The Lucifer titi has previously been treated as part of C. torquatus, the collared titi.
This species occurs near the interfluve north of the Solimões and Napo Rivers, and south of the Japurá River. The Lucifer titi is found in lowland Colombian Amazonia up to about 500 m (1,600 ft) of altitude in Putumayo and probably about the same in Caquetá. Outside of Colombia this species extends from the Napo River northward to the Ecuadorian Amazon.
The pelage of this species is basically blackish but intermixed with many hairs on the back (extending to the top of the crown) and flanks with many reddish brown hairs, giving the animal a definite reddish appearance in the sunlight.
Robinson et al. also report a birth season of December to January for the species in Peru at 4ºS. Why this specific birth season should be chosen by the species in such widely divergent places both north and south of the equator with different... Wikipedia →

Possible
About 20% of wildlife watchers report a Lucifer Titi sighting in Amacayacu National Natural Park on a given day, based on 9 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 6th most-seen of the 9 mammals we can rate there. Over three days the chance rises to about 60%, and over a week to about 90%, if each day is a fresh chance.
February, May and August
In those months about 40% of wildlife watchers report a Lucifer Titi in Amacayacu National Natural Park on a given day, against under 5% in January and June–July, the lowest months.
Between 11 am and 2 pm
Across all the parks we cover, that three-hour window holds the most Lucifer Titi sightings with a recorded time, and about 8 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
2nd of 2
Of the 2 parks where we can rate Lucifer Titi sightings, Amacayacu National Natural Park ranks 2nd at about 20%. The best odds are in Cuyabeno Wildlife Reserve (Ecuador, about 40%).
Same order: Primates
The closest relatives of the Lucifer Titi that you can see in Amacayacu National Natural Park (order Primates) are Ecuadorian Squirrel Monkey (about 40%), Western Pygmy Marmoset (about 30%) and Common Woolly Monkey (about 20%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Lucifer Titi is recorded against all the mammals logged in Amacayacu National Natural Park (9 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.
